Liza is driving to her sister's house 360 miles away. After 4 hours, Liza is 2/3 of the way there.   How many more hours  does Liza have to drive?

Answer:

Liza need to drive 2 more hours to reach her sister house

Solution:

Given that Liza is driving to her sister's house 360 miles away

So total distance = 360 miles

After 4 hours, Liza is 2/3 of the way there.

[tex]\frac{2}{3} r d \text { of total distance }=\frac{2}{3} \times 360=240[/tex]

So Liza has covered 240 miles in 4 hours

Let us find the speed

The relation between distance and speed is given as:

[tex]speed = \frac{distance}{time}[/tex]

[tex]speed = \frac{240}{4} = 60[/tex]

Thus speed = 60 miles per hour

Assuming speed is same throughout the journey, let us calculate the time taken to complete remaining distance

Remaining distance = 360 - 240 = 120 miles

Now distance = 120 miles and speed = 60 miles per hour

[tex]time taken = \frac{distance}{speed}\\\\time taken = \frac{120}{60} = 2[/tex]

Thus Liza need to drive 2 more hours to reach her sister house

Answer:

Step-by-step explanation:

The vertex is of the form (h, k).  The general equation of a quadratic in vertex form is

[tex]y=(x-h)^2+k[/tex]

where h is the x coordinate of the vertex and k is the y coordinate of the vertex.  The important thing to remember is that the "x -" part of the formula is constant, it doesn't change.  So if our expression inside the parenthesis is

(x + 3), it is understood to be (x - (-3)) which indicates movement to the left.  The "+ k" part is not taken literally.  If we have a + 2 at the end of our equation we are moving up 2; if we have a -1 at the end, we are moving down 1.  Our vertex then is located at (-3, -1)

The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

[tex]y = -4x+9[/tex]

Step-by-step explanation:

Given equation of line is:

[tex]4y=x-8[/tex]

We have to convert the given line in slope-intercept form to find the slope of the line

So,

Dividing both sides by 4

[tex]\frac{4y}{4} =\frac{x-8}{4}\\y = \frac{1}{4}x-\frac{8}{4}\\y = \frac{1}{4}x-2[/tex]

Let m1 be the slope of given line

Then

[tex]m_1 = \frac{1}{4}\\[/tex]

Let m2 be the slope of line perpendicular to given line

As we know that produt of slopes of two perpendicular lines is -1

[tex]m_1.m_2 = -1\\\frac{1}{4} . m_2 = -1\\m_2 = -1*4\\m_2 = -4[/tex]

The slope intercept form of line is given by:

[tex]y = m_2x+b[/tex]

Putting the value of slope

[tex]y = -4x+b[/tex]

to find the value of b, putting (3,-3) in equation

[tex]-3 = (-4)(3) + b\\-3 = -12 +b\\b = -3+12\\b = 9[/tex]

Putting the value of b in the equation

[tex]y = -4x+9[/tex]

Hence,

The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

[tex]y = -4x+9[/tex]

Therefore, the equation of the line in function notation is f(x) = -4x + 9.

Answer: Option B.

Step-by-step explanation:

For this exercise it is important to remember that, by definition, a relation is a function if and only if each input value has an unique output value.

The input values are the values of the variable "x" and the output values are the values of the variable "y".

You can observe in the table shown in the picture, that the input value -2 has two different output values:

[tex]x=-2,y=3\\\\x=-2,y=-13[/tex]

Notice that the input vale -1 has two different output values too:

[tex]x=-1,y=-1\\\\x=-1,y=-9[/tex]

Therefore, based on this, you can conclude that the information given in the table is a relation but not a function.

Answer:

Step-by-step explanation:

Curved surface Area = 2πrh

Area of its bases = 2πr²

6* Area of its bases = 4 * Curved surface Area

6 * 2πr² = 4 *2πrh

r²  / r = 4 * 2* π*12 / 6 * 2 * π   { substituting h =12 cm}

r = 4*2

r = 8 cm

Curved surface Area = 2πrh

= 2 * 3.14 * 12 * 8

= 602.88 Sq. cm

Answer:

603.42

Step-by-step explanation:

Curved Surface Area = 2πrh sq.cm

Area of the base = πr² sq. cm

Sum area of the base = πr² + πr² = 2πr² sq.cm

                               A.T.Q

4(2πrh) = 6x2πr²

8πrh = 12πr²

2h = 3r

r = 8 cm

Curved Surface Area = 2πrh

Final answer:

To find the third angle of a triangle, add the two known angles and subtract from 180 degrees. In this case, the third angle measures 90 degrees since the sum of the two given angles is 90 degrees.

Explanation:

When determining the measure of the third angle in a triangle, we utilize the fundamental property that the sum of all angles in a triangle equals to 180 degrees. Given that two of the angles measure 18° and 72°, we can find the third angle by subtracting the sum of these two angles from 180°.

The calculation is as follows:

Therefore, the measure of the third angle in the triangle is 90 degrees.

A photographer stands 60 yards from the base of a lighthouse and observes that the angle between the  ground and the top of the lighthouse is 41° How tall is the lighthouse?

Answer:

The height of lighthouse is 52.2 yards

Solution:

Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the  ground and the top of the lighthouse is 41 degree

The diagram is attached below

Consider a right angled triangle ABC

AB is the height of the lighthouse

BC is the distance between the base of a lighthouse and Photographer

As per given, BC = 60 yards

Angle between the  ground and the top of the lighthouse is 41 degree

Angle ACB = 41 degree

To find: height of lighthouse i.e AB = ?

We know that,

[tex]tan(\angle ACB) = \frac{Perpendicular}{Base}[/tex]

Here Base is BC and perpendicular is AB

[tex]\tan 41^{\circ}=\frac{A B}{B C}[/tex]

Substituting the values,

[tex]\begin{aligned}&\tan 41^{\circ}=\frac{A B}{60}\\\\&0.8692=\frac{A B}{60}\\\\&A B=0.8692 \times 60=52.157 \approx 52.2\end{aligned}[/tex]

Thus the height of lighthouse is 52.2 yards

16 hours and 20 minutes.

Step-by-step explanation:

Please consider the complete question.

Rita's family is moving to Grand Junction to Dallas, which is 980 miles. The moving van averages 60 miles each hour. About how many hours does the van take to reach Dallas?

To find the time taken by van to reach Dallas, we will divide total distance by speed.

[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]

[tex]\text{Time taken to reach Dallas}=\frac{980\text{ Miles}}{60\frac{\text{ Miles}}{\text{Hour}}}[/tex]

[tex]\text{Time taken to reach Dallas}=\frac{980\text{ Miles}}{60}\times \frac{\text{ Hour}}{\text{Miles}}[/tex]

[tex]\text{Time taken to reach Dallas}=\frac{98}{6}\text{ Hour}[/tex]

[tex]\text{Time taken to reach Dallas}=16.3333\text{ Hour}[/tex]

Let us convert 0.3333 hours into minutes by multiplying 0.3333 by 60.

[tex]0.3333\times 60=19.998\approx 20[/tex]

Therefore, it will take 16 hours and 20 minutes for the van to reach Dallas.

Final answer:

To calculate the time it takes for the van to reach Dallas, divide the distance from Grand Junction to Dallas by the average speed of the van.

Explanation:

To calculate the time it takes for the van to reach Dallas, we need to divide the distance from Grand Junction to Dallas by the average speed of the van.

The distance from Grand Junction to Dallas is not provided in the question, so we cannot calculate the exact time taken. However, if we are given the distance, we can use the formula:

Time = Distance / Speed

For example, if the distance is 300 miles, and the van's average speed is 60 miles per hour, then the time taken would be:

Time = 300 / 60 = 5 hours

Solutions are -10 and 26

Step-by-step explanation:

( - the abolute sign I'm using

( x - 8 ) + 2 = 20

( x - 8 ) = 18

x - 8 = 18 (postive case)

x - 8 + 8 = 18 + 8

x = 26

( x - 8 ) = 18

x - 8 = -18 (negative case)

x - 8 + 8 = -18 + 8

x = -10

Both Henry and Colin have a ratio of 4, so Colin gets the same amount as Henry, so we know Colin has 56.

Brian's ratio is 5, so for every 4 Colin gets, brian gets 5 ( 1 more).

Divide Colin's quantity by 4 :

56/4 = 14

Brain gets 14 more.

The graph of y = x is transformed by a reflection about the x-axis, a horizontal translation to the left by 2 units, and a vertical translation upward by 3 units to produce the graph of y = -(x + 2)^2 + 3.

The given equation is y = -(x + 2)^2 + 3, and we need to describe the transformations of the graph of y = x that will produce this graph.

The first transformation is the reflection about the x-axis, which is indicated by the negative sign in front of the original equation. This flips the graph upside down.

The second transformation is the horizontal translation to the left by 2 units, which is indicated by the addition of 2 inside the parentheses. This shifts the graph 2 units to the left.

The third transformation is the vertical translation upward by 3 units, which is indicated by the addition of 3 to the entire equation. This moves the graph 3 units up.

The question asks for equivalent expressions to 3-8/3-4. After clarifying and simplifying the expression, we determined that the equivalent expressions are 3-12 (A) and 13/12 (F).

The question is asking us to determine which expressions are equivalent to 3−83−4. First, let's clarify this expression. The symbols − and − can stand for subtraction or negative signs, making the expression ambiguous. However, we can interpret this as a subtraction problem with mixed numbers, which would be processed as 3 minus 8 thirds minus 4. Converting the mixed numbers to improper fractions, we get: 3−(8/3)−4 which simplifies to (9/3)−(8/3)−(12/3). This simplifies to 1/3−(12/3), or 1/3− 4, which then further simplifies to −(⅔).

When we look for equivalent expressions, we have the following options:

You would require the table with the number of males and females who prefer either pink or yellow lemonade at the state fair.

                      Pink Lemonade         Yellow Lemonade       TOTAL

Male                    156                                104                          260

Female                  72                               48                          120

TOTAL                 228                               152                         380

P(pink lemonade | female) = 72 / (48 + 72) = 72 / 120 = 0.6

P(pink lemonade) = (156 + 72) / (156 + 72 + 104 + 48) = 228 / 380 = 0.6

Therefore, The event "prefers pink lemonade" and "female" are independent because P(pink lemonade | female) = P(pink lemonade) = 0.6

Answer:

P(pink lemonade | female) = P(pink lemonade) = 0.6.

The question is incomplete. Here is the complete question:

The height of a wooden pole, h, is equal to 15 feet. A taut wire is stretched from a point on the ground to the top of the pole. The  distance from the base of the pole to this point on the ground, b. is equal to 8 feet. What is the length of the wire?

Answer:

Length of wire = 17 feet

Step-by-step explanation:

Given:

The height of the wooden pole is, [tex]h=15\ ft[/tex]

The distance from the base of the pole to this point on the ground is, [tex]b=8\ ft[/tex]

Let the length of the wire be 'l'.

Now, consider the triangle formed by the pole, the base, and the wire. The length of the wire is the slant length and hence the hypotenuse of the triangle.

Using Pythagorean theorem, we can find the hypotenuse.

[tex](Hypotenuse)^2=(height)^2+(base)^2\\l^2=h^2+b^2[/tex]

Plug in the given values and solve for 'l'. This gives,

[tex]l^2=15^2+8^2\\\\l^2=225+64\\\\l^2=289\\\\l=\sqrt{289}\\\\l=\pm17[/tex]

As length can never be negative, we ignore the negative result.

Therefore, the length of the wire is 17 feet.
