One Pound Of Grapes Costs $1.55. Which Equation Correctly Shows A Pair Of Equivalent Ratios That Can

Answers

Answer 1
1.55 / 1 = x / 3.5....$ 1.55 to 1 lb = $ x to 3.5 lbs

first one <==

it could have also been : 1 / 1.55 = 3.5 / x...but that is not an answer choice
Answer 2

Answer:

A

Step-by-step explanation:

One pound of grapes costs $1.55. To find the amount x of 3.5 pounds of grapes we would have to multiply 1.55 by 3.5. This would give us the amount x we would have to pay for them.

If we examine the 4 equivalent radios shown in the pictures, we will see that the first one correctly shows this equivalency.

[tex]\frac{1.55}{1} = \frac{x}{3.5}[/tex]

The other 3 pictures show radios that would give us x = 3.5 / 1.55 (second and third) or x = 1.55 / 3.5 (fourth picture).

Therefore, the correct answer would be a)

Answers

The answer to this question is A.)

Answer:

Step-by-step explanation:

They have 30 gallons of paint and for each hour that passes, they use 3 gallons of paint. Therefore, we can express that as a function:

y = -3x + 30

where y = gallons left

and x = hours passed

Therefore, the end points are (0, 30) and (10, 0)

Using our function when 0 hours has passed:

y = -3(0) + 30

y = 30

Therefore one endpoint is when x = 0 y = 30 or (0,30)

Using our function when 10 hours has passed:

y = -3(10) + 30

y = -30 + 30

y = 0

Therefore one endpoint is when x = 10 y = 0 or (10, 0)

The modulo of the expressions are computed as follows: (a+a) mod 7 = 4, (a+b) mod 7 = 0, (3a) mod 7 = 6, and (2b) mod 7 = 3.

Explanation:

I'm sorry, but I'm afraid there might have been some confusion in your input. If you wanted the remainders of different expressions when divided by 7, here are the steps:

Given that a mod 7 = 2 and b mod 7 = 5, you can use modular arithmetic to compute the modulo of expressions including a and b:

(a+a) mod 7 = 2a mod 7. Since a mod 7 = 2, then 2a mod 7 = 4 mod 7.(a+b) mod 7 = 2+5 mod 7 = 7 mod 7 = 0.(3a) mod 7 = 6 mod 7.(2b) mod 7 = 10 mod 7 = 3.

Find the largest number δ such that if |x − 1| < δ, then |5x − 5| < ε, where ε = 0.1. δ ≤ repeat and determine δ with ε = 0.01.

Answers

[tex]|5x-5|=5|x-1|<\varepsilon\implies|x-1|<\dfrac\varepsilon5=\delta[/tex]

So for [tex]\varepsilon=0.1[/tex], we get [tex]\delta=50[/tex]; for [tex]\varepsilon=0.01[/tex], we get [tex]\delta=500[/tex].

Hi, here we want to "finish" a delta-epsilon proof.

We will find that the maximum delta is: δ = 0.02

We just want to find the value of δ such that:

[tex]|x - 1| < \delta[/tex]

Implies that:

[tex]|5x - 5| < \epsilon[/tex]

Well, let's start with the second expression:

[tex]|5x - 5| < \epsilon[/tex]

We can take the 5 out of the absolute value:

[tex]5*|x - 1| < \epsilon[/tex]

Now we can divide both sides by 5:

[tex]|x - 1| < \epsilon/5[/tex]

Now, if you look at the above expression, in the left side we have the same thing as in the delta inequality.

So for now we have:

[tex]|x - 1| < \epsilon/5[/tex]

[tex]|x - 1| < \delta[/tex]

From this is easy to conclude that the maximum value that delta can take is:

δ = ε/5

And we know that ε = 0.1, then we have:

δ = 0.1/5 = 0.02

δ = 0.02

The maximum value that delta can take is 0.02

Then we need to repeat it for ε = 0.01, so we get:

δ = 0.01/5 = 0.002

δ = 0.002

there are 2 more than 3 times as many parrots as finches at the pet store, if there's a total of 18 parrots and finches, how many are parrots and how many are finches

Answers

Final answer:

To solve this problem, you can set up a system of equations. There are 4 finches and 14 parrots.

Explanation:

To solve this problem, we can set up a system of equations based on the given information. Let's assume that the number of finches is 'x'. According to the problem, there are 2 more than 3 times as many parrots as finches. This can be written as:

Parrots = 3x + 2

Since the total number of parrots and finches is 18, we can set up another equation:

Parrots + Finches = 18

Substituting the first equation into the second equation, we get:

(3x + 2) + x = 18

Combining like terms, we have:

4x + 2 = 18

Subtracting 2 from both sides, we get:

4x = 16

Dividing both sides by 4, we find that:

x = 4

So, there are 4 finches and 3(4) + 2 = 14 parrots.

An investment firm recommends that a client invest in bonds rated AAA, A, and B. The average yield on AAA bonds is 4%, on A bonds 6%, and on B bonds 11%. The client wants to invest twice as much in AAA bonds as in B bonds. How much should be invested in each type of bond under the following conditions?
A.  The total investment is $26,000, and the investor wants an annual return of $1,620 on the three investments.
B.  The values in part A are changed to $38,000 and $2,360, respectively
A.  The client should invest $(?) in AAA bonds, $(?)in A bonds, and $(?)in B bonds.

Answers

Part A.

1) Variables:

X: amount invested in AAA bonds

Y: amount invested in A bonds

Z: amount invested in B bonds.

2) Return:

4%* X + 6% * Y + 11% * Z = 1620

3) Investment:

 X + Y + Z = 26,000

4) Ratio between AAA and B bonds.

X = 2*Z

5) Solution of the system of equations:

Replace X with 2Z in the two first equations:

2Z * 4% + Y * 6% + Z * 11% = 1620

=> 0.08Z + 0.06Y + 0.11Z = 1620

=> 0.19Z + 0.06Y = 1620

2Z + Y + Z = 26,000

=> 3Z + Y = 26,000 => Y = 26,000 - 3Z

Replace Y with 26,000 - 3Z

0.19Z + 0.06(26,000 - 3Z) = 1620

0.19Z + 1560 - 0.18Z = 1620

0.01Z = 1620 - 1560

0.01Z = 60

Z = 60 / 0.01 = 6000

=> X = 2*6000 = 12,000

=> Y = 26,000 - 12,000 - 6,000 = 8,000

Answer: 12,000 in bonds AAA, 8,000 in bonds A, and 6000 in bonds B.

Part B.

2) Return:

0.04X + 0.06 Y + 0.11Z = 2360

3) Investment:

 X + Y + Z = 38,000

4) Ratio between AAA and B bonds.

X = 2Z

5) Solution of the system of equations:

Replace X with 2Z in the two first equations:

=> 0.08Z + 0.06Y + 0.11Z = 2360

=> 0.19Z + 0.06Y = 2360

2Z + Y + Z = 38,000

=> 3Z + Y = 38,000 => Y = 38,000 - 3Z

Replace Y with 38,000 - 3Z

0.19Z + 0.06(38,000 - 3Z) = 2360

0.19Z + 2280 - 0.18Z = 2360

0.01Z = 2360 - 2280

0.01Z = 80

Z = 80 / 0.01 = 8000

=> X = 2*8000 = 16,000

=> Y = 38,000 - 16,000 - 8000 = 14,000

Answer: 16,000 in AAA bonds, 14,000 in A bonds, and 8,000 in B  bonds.

We multiple 0.4 divided by 0.02, by 100 over 100. We can do this because 100 over 100 is still technically 1. We are just making the terms simpler and easier to understand.

0.4 100 40
--------- x --------- = -------
0.02 100 2

Now that we know (0.4/0.02) equals (40/2), we can solve the equation easily.
40 divided by 2 equals 20.

Answer: 20

Final answer:

To divide 0.4 by 0.02, transform the division problem into 40 divided by 2 by moving the decimal places to the right, resulting in the answer 20.

Explanation:

To solve the division of two decimal numbers, 0.4 divided by 0.02, you can follow these steps:

First, count the number of decimal places in the divisor (0.02), which is 2.Move the decimal place in both the divisor and the dividend to the right by the same number of places, turning 0.02 into 2 and 0.4 into 40.Now divide the transformed dividend (40) by the transformed divisor (2).

The division now looks like 40 ÷ 2, which equals 20.

So, 0.4 divided by 0.02 equals 20. This method allows us to divide decimal numbers by converting them into whole numbers, simplifying the calculation.

m∠X’Y’Z’ = 2 × m∠XYZ

Answers

It is fine that you did not include the measure of angle XYZ in your posting.

This question is testing your knowledge of the four types of transformations.
1) Translations - an item is "slid" to a new location.
2) Reflections - an item is "flipped" (usually over the x-axis or y-axis)
3) Rotations - an item is rotated, usually around the origin (the point (0,0) is the center of most rotations, especially in high school math).
4) Dilations - an item is enlarged or reduced by a certain ratio.

It the first three, the image after the transformation is congruent to the pre-image.  It has the same size and shape.  It is simply flipped, rotated, slid...

But... in the fourth, dilation, the image now has a different size.  It is still, however the same shape.

In geometry terms, after the first three transformations, the image is still "congruent" to the pre-image.  After dilation, the image is "similar" but not "congruent."

So... all that to say that when you rotate an angle around the origin, the measure of the angle doesn't change.

So the first choice is correct.  The measure of the image of the angle is the same as the measure of the angle.

The bacteria population will be 40,960 in 11 hours

Answer:

1)

t=5 hours.

2)

40960 cells.

Step-by-step explanation:

A scientist studying bacteria begins with 20 cells.

The bacteria population doubles every hour.

Let P(t) determines the population of the bacteria in 't' hours.

Hence, by the given information our function P(t) is modeled as:

[tex]P(t)=20\times 2^t[/tex]

Now, we have to find the value of 't' such that:

P(t)>500

i.e.

[tex]20\times 2^t>500\\\\\\2^t>\dfrac{500}{20}\\\\2^t>25[/tex]

on taking logarithmic function on both side we get:

[tex]t\log 2>\log 25\\\\t>\dfrac{\log 25}{\log 2}\\\\t>4.64[/tex]

i.e. after 5 hours the population of the bacteria will exceed 500.

Now we have to find the value of function P(t) when t=11.

i.e.

[tex]P(11)=20\times 2^{11}\\\\P(11)=20\times 2048\\\\P(11)=40960[/tex]

Hence , the population of bacteria after 11 hours is:

Sun is the brightest object in the sky of the Earth. It is a giant spherical star, composed of hot plasma that is located at the center of the Solar System. The diameter of the Sun is about 1.391 million km.

Mars, also known as the Red Planet, is one of the four terrestrial planets. It is the fourth planet of the Solar System. It is the second-smallest planet having diameter of about 6,779 km.

Now, diameter of Mars ÷ diameter of the Sun ≈ 6,779 km ÷ 1391000 km ≈ 1 ÷ 200

⇒ diameter of Mars ≈ (1 ÷ 200) × diameter of the Sun

Therefore, the diameter of Mars is approximately 1/200 of the diameter of the Sun.

if the smaller of two consecutive intergers is subtracted from two times the larger then the result is 17 . find the intergers

Answers

Two consecutive integers (x) and (x+1)
2 (x+1) - (x) = 17
2x + 2 - x = 17
x + 2= 17
x + 2 - 2 = 17 - 2
x=15
and x + 1 = 15 + 1 = 16

15, 16 are your numbers.
