Answer:

The perimeter of rectangle is [tex]18\ cm[/tex]

Step-by-step explanation:

Let

x------> the length of rectangle

y----> the width of rectangle

we know that

The area of the constructed figure is equal to

[tex]A=xy+2x^{2} +2y^{2}\\A=120\ cm^{2}[/tex]

so

[tex]120=xy+2x^{2} +2y^{2}[/tex] -----> equation A

[tex]x=y+5[/tex] -----> equation B

substitute equation B in equation A

[tex]120=y(y+5)+2(y+5)^{2} +2y^{2}\\120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\5y^{2}+25y+50-120=0\\5y^{2}+25y-70=0[/tex]

using a graphing calculator to resolve the quadratic equation

the solution is

[tex]y=2\ cm[/tex]

Find the value of x

[tex]x=2+5=7\ cm[/tex]

Find the perimeter of rectangle

The perimeter of rectangle is equal to

-3 + 1 = -2

8 + 2 = 10

-2/10 = -1/5

Answer = -1/5

The slope of the line through the points (2, 1) and (8, 3) is calculated using the slope formula and is -1/5.

To find the slope of a line passing through two points, you will need to use the slope formula, which is:

(change in y) / (change in x)or (y2 - y1) / (x2 - x1).

For the points given (–2, –1) and (8, –3), you would calculate the slope as follows:

Slope (m) = (-3 - (-1)) / (8 - (-2)) = (-3 + 1) / (8 + 2) = (-2) / (10) = -1/5.

So, the slope of the line through the points (–2, –1) and (8, –3) is -1/5.

Answer:

9cos(46x) + 9cos(12x)

Step-by-step explanation:

18cos(29x)cos(17x)

According to Product-Sum identities

cos(α)cos(β)= (1/2)[cos(α+β)+cos(α-β)]

Putting α=29x and  β=17x in Product-Sum identity we get

= 18×(1/2)[cos(29x+17x)+cos(29x-1`7x)]

Dividing 18 by 2 we get 9

= 9[cos(46x)+cos(12x)]

Multiplying 9 with both the terms we get

= 9cos(46x)+9cos(12x)

Prediction for the number of unsuccessful rolls is 15.

There is [tex]\frac{1}{6}[/tex] chance of rolling number 6 on the cube. If we want to find out what is the prediction for rolling number 6 in 18 rolls, we need to multiply [tex]6*\frac{1}{6}[/tex] which is 3. So if we roll a cube 18 times, we will probably got number 6 three times. When we subtract 3 from 18 (18-3), we get 15. That is the answer to your question.

Answer:

Don't take my word for it but I think it would be 55% chance. I'm Probably wrong.

Step-by-step explanation:

Answer:

9% or 0.09

Step-by-step explanation:

Given, chance of land having oil is 45%. Which is 0.45

So, chance of land NOT having oil is  percent. Which is 0.55

Given, kit's accuracy rate of finding oil as 80%. Which is 0.80

So, kit's accuracy rate of NOT finding oil is   percent. Which is 0.20

These 2 events are INDEPENDENT, which means that the probability of one event occurring does not affect the probability of another event occuring.

The formula, if we let the two evens be A and B, is:

P(A and B)=P(A) * P(B)

Now, "the probability that the land has oil (event A)AND the test predicts that there is no oil (event B)" will be:

P(A and B) = P(A) * P(B)

Hence, the probability is 0.09 or 9%

n < 18

Step-by-step explanation:

The condition you are looking for is that

                                         94 + 4.50n < 175

Subtract 94 from each side     4.50n < 81

Divide each side by 4.50                 n < 18

The number of devices must be fewer than 18 for the new plan to cost less than the current plan.

The diagram is a graph of the inequality 94 + 4.50n < 175. Any value of n less than 18 (that is, in the pink zone and not on the vertical dashed line) will satisfy the inequality.

Answer:

Step-by-step explanation:

"For each nickel, she has one dime"

That means she has the same number of nickels and dimes.

"for each dime she has one quarter"

That means she has the same number of quarters and dimes.

She has the same number of each coin.

Let's say she has x coins of each type.

The nickels are worth 0.05x; the dimes are worth 0.10x. The quarters are worth 0.25x. Altogether, the coins are worth

0.05x + 0.10x + 0.25x

We are told her coins are worth $1.20, so we set those two amounts equal and solve for x.

0.05x + 0.10x + 0.25x = 1.20

0.40x = 1.20

x = 1.20/0.40

x = 3

She has 3 coins of each type. Since there are 3 types of coins, she has 9 coins.

Dawn has a total of 9 coins, which include 3 nickels, 3 dimes, and 3 quarters.

The subject of this question is a math problem involving counting coins. In this scenario, dawn has a total of $1.20 in nickels, dimes, and quarters. And the number of nickels, dimes and quarters are equal since for every nickel Dawn has, she also has a dime and a quarter.

Now, the value of a nickel is $0.05, a dime is $0.10 and a quarter is $0.25. So, the total value of a nickel, a dime and a quarter is $0.40. Therefore, since the total amount of money she has is $1.20, we divide that amount by the total value of each group of coins: $1.20 / $0.40 gives us 3.

So Dawn has 3 nickels, 3 dimes, and 3 quarters, for a total of 9 coins.

Answer:

The volume of the dirt in the flowerbed is [tex]1,056\ in^{3}[/tex]

Step-by-step explanation:

we know that

To find the volume of the dirt in the flowerbed, multiply the long by the width by the depth

so

[tex]V=(22)(8)(6)=1,056\ in^{3}[/tex]

Final answer:

To calculate the volume of dirt in a rectangular flowerbed with dimensions of 22 inches by 8 inches by 6 inches, use the formula Volume = length × width × height, resulting in 1056 cubic inches.

Explanation:

The question asks for the volume of dirt a rectangular flowerbed can hold. To find the volume, we use the formula Volume = length × width × height. Given the dimensions are 22 inches (length) by 8 inches (width) by 6 inches (height), we calculate the volume as:

Volume = 22 in. × 8 in. × 6 in. = 1056 cubic inches. Therefore, the volume of the dirt in the flowerbed is 1056 cubic inches.

Check the picture below.

the idea being, the winding path is made out of semi-circles, each semi-circle has a diameter of 3, as you see there in the picture.

now, if we could just take two semi-circles, we'd have a full circle, with a diameter of 3, so from all 4 semi-circles we can actually get two full circles, as you see there, and the circumference of those two full circles, is the length of the winding path.

[tex]\bf \textit{circumference of a circle}\\\\ C=\pi d~~ \begin{cases} d=diameter\\[-0.5em] \hrulefill\\ d=3 \end{cases}\implies C=3\pi \qquad \stackrel{\textit{two circles added together}}{3\pi +3\pi \implies 6\pi ~~\approx~~18.85}[/tex]

Answer:

The arc length of the partial circle is [tex]6\pi\ units[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

In this problem we have a 3/4 of a circle

so

the circumference is equal to

[tex]C=(\frac{3}{4})2\pi r[/tex]

[tex]C=\frac{3}{2}\pi r[/tex]

we have

[tex]r=4\ units[/tex]

substitute

[tex]C=\frac{3}{2}\pi (4)[/tex]

[tex]C=6\pi\ units[/tex]

Answer:

[tex]x^2-9[/tex]

Step-by-step explanation:

We are given the following expression and we are to divide it:

[tex] \frac { x ^ 4 - x ^ 2 - 6 } { x ^ { 2 } + 8 } [/tex]

We divide the first term [tex]x^4[/tex] by [tex]x^{2}+8[/tex] and get [tex]x^{2}[/tex] in the quotient so then we are left with [tex]-9x^{2} -6[/tex].

Further [tex]-9x^{2} -6[/tex] is divided by [tex]x^{2}+8[/tex] to get [tex]-9[/tex] in the quotient and we are left with 66 as the remainder.

So we get the quotient [tex]x^2-9[/tex] and remainder [tex]66[/tex].

Equation: [tex]600=\frac{20b)}{2}[/tex]

Base: 60 feet.

Step-by-step explanation:

The formula for calculate the area of a triangle is:

[tex]A=\frac{bh}{2}[/tex]

Where:

A: is the area of the triangle.

b: is the base of the triangle.

h: is the heigth of the triangle.

Knowing the area of the triangle and its height, you can write the equation:

[tex]600=\frac{20b}{2}[/tex]

Where b is the base in feet of the A-frame house.

To solve it:

Multiply both sides of the equation by 2.

Divide both sides of the equation by 20.

Then:

[tex](2)(600)=(\frac{20b}{2})(2)\\\\1200=20b\\\\\frac{1200}{20}=\frac{20b}{20}\\\\60=b[/tex]

The base of the A-frame house is 60 feet.

The number √1/√49 is a rational number.

Given a number √1/√49.

Here the numerator and the denominator includes the square root.

We can see that both the numbers inside the square root is a perfect square.

So the number can actually be written in the integer form.

So,

√1/√49 = 1/7, since 7² = 49

Now rational numbers are numbers which can be written in the form of p/q where p and q are integers with q not equal to 0.

Here the number can be written as 1/7, where 1 and 7 are integers.

Hence it is rational.

The second spot to the right of the decimal is the hundredths place. Ex. .00

The third spot to the right of the decimal is the thousandths place. Ex. .000

Since you are trying to round to the nearest hundredth you look at the thousandths place. If it is 5 or higher you round up. If it is under 5 you round down.
