WILL GIVE BRAINLIEST George is building a fence around a rectangular dog run. He is using his house as one side of the run. The area of the dog run will be 240 square feet. The length of the run is 30 feet, and the width is (30 minus x) feet. The diagram below shows his plan. Recall the formulas for area and perimeter: A = lw and P = 2l + 2w. A rectangle labeled Dog run has a length of 30 feet and width of (30 minus x) feet. How many feet of fencing will George need for the dog run? 22 feet 68 feet 76 feet 82 feet

Answer:

20 should expect to get lizard treats

Step-by-step explanation:

There are 4+10+6 treats = 20 treats

10 out of the 20 are lizard treats

10/20 = 1/2

There are 40 people

1/2 * 40 = 20

20 should expect to get lizard treats

Hey there! :)

Answer:

m∠QPR = 25°.

Step-by-step explanation:

Given:

m∠QPS = 40°

m∠RPS = 8x + 7°

m∠QPR = 9x + 16°

m∠QPS = m∠RPS + m∠QPR, therefore:

40° = 8x + 7° + 9x + 16°

Combine like terms:

40° = 17x + 23°

Subtract 23° from both sides:

17° = 17x°

Divide both sides by 17:

x = 1°

If m∠QPR = 9x + 16°, substitute in 1 for 'x':

9(1) + 16 = 9 + 16 = 25°.

We need to find the value of x.

If R is on the interior of of <QPS, then m<QPR + m<RPS = m<QPS.

Now substitute the measures into the equation.

9x + 16 + 8x + 7 = 40.

Now combine like terms to get 17x + 23 = 40.

Now subtract 23 form both sides to get 17x = 17.

Now divide both sides by 17 to find that x = 1.

Now to find m<QPR which measures 9x + 16°, we can substitute in a 1.

So we have 9(1) + 16 which is 25.

So m<QPR is 25°.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

To most closely estimate the difference, I would round 62,980 to the nearest thousand, so it will be 63,000. That is because when rounding, 63,000 is large enough so that adding will be easy, and 62,980 is relatively close to 63,000.

I would round 49,625 to the nearest thousand, since it would make the subtraction easier and 49,625 is only 375 units away from 50,000.

63,000 - 50,000 = about 13,000.

Answer:

Step-by-step explanation:

Slope intercept form :  y - y1 = m(x -x1)

m = 3/2

(x1, y1) = (6, 1)

[tex]y - 1 = \frac{3}{2}(x - 6)\\\\y -1 = \frac{3}{2}*x -\frac{3}{2}*6\\\\y-1=\frac{3}{2}x-3*3\\\\y-1=\frac{3}{2}x-9\\\\y=\frac{3}{2}x-9+1\\\\y=\frac{3}{2}x -8[/tex]

Answer:

y=3/2 x  -8

Step-by-step explanation:

The slope should be in front of the x and the y intercept should be right after the x to create the slope intercept form. I used a graphing calculator which continued the line of 6,1 with a slope of 3/2 and then got

y=3/2x-8

Answer: Choice A

Step-by-step explanation:

She can only buy 3 pizzas. 14 times 3 is 42. 42 plus 7.50 is 49.50. Another 14 dollars would be over. So 24 SLICES she can afford.

Here, we are required to identify the inequality that describes Jacque's pizza purchase scenario and also the largest number of slices that Jacque can afford

Choice 1 which is ;

Choice 1 which is ;7.50 + 14 P < 60Jacque can afford to buy 30slices of pizza

First,

The inequality which describes the scenario is :

Choice 1 which is ;

And to determine the largest number of slices that Jacque can afford, we have to solve for P first.

However, the question requires that we determine how many slices she can afford to buy,

Jacque can afford to buy 3.75 × 8 slices of pizza.

Jacque can afford to buy 30slices of pizza

AX=2 BY=5 CZ=3

Step-by-step explanation:

Lets call AX (x). Once you do so, one can tell that AZ=5-x. CZ is also 5-x. BX is also x. Therefore you can say that BY=7-x which makes CY 7-x. Now for side YZ, CZ is 5-x and CY is 7-x.

5-x+7-x=8

solving that you get x=2

AX=2

BY=7-x=5

CZ=5-x=3

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

Given

Shape: Parallelogram PQRS

[tex]PQ = x^2 - 10[/tex]

[tex]SR = 3x[/tex]

Required

Find all possible values of x

Every parallelogram have parallel and equal opposite sides;

From the given parameters, one can easily deduce that PQ and SR are opposite sides;

This implies that

[tex]PQ = SR[/tex]

Substitute values of PQ and SR

[tex]x^2 - 10 = 3x[/tex]

Subtract 3x from both sides

[tex]x^2 - 10 -3x = 3x - 3x[/tex]

[tex]x^2 - 10 -3x = 0[/tex]

Rearrange

[tex]x^2 -3x- 10 = 0[/tex]

Now, we have a quadratic equation;

Expand the above expression

[tex]x^2 +2x-5x- 10 = 0[/tex]

Factorize

[tex]x(x+2)-5(x+2) = 0[/tex]

[tex](x-5)(x+2) = 0[/tex]

[tex]x - 5 = 0[/tex]   or    [tex]x + 2 = 0[/tex]

Solve for x in both cases

[tex]x = 5[/tex] or [tex]x = -2[/tex]

But x can't be negative;

So, the possible value of x is

[tex]x = 5[/tex]

Step-by-step explanation:

This is a function since no value gives two different outputs

The domain is (m,n,p,q) since it's the values that we input in the function

=============================================

Work Shown:

a = 3 is the first term

r = 2 is the common ratio

Sn = a*(1-r^n)/(1-r) ... sum of the first n terms

S8 = 3*(1-2^8)/(1-2) ... sum of the first 8 terms

S8 = 3*(-255)/(-1)

S8 = 765

----------

We can generate the first 8 terms to get 3, 6, 12, 24, 48, 96, 192, 384. Each new term is found by multiplying the previous one by 2.

Then add them up to get 3+6+12+24+48+96+192+384 = 765. We get the same result.

Answer:

1/8

Step-by-step explanation:

ok so before i start i wanna say that this is gonna get confusing.....

Since the pizza is a whole quantity let us take it as 1.

Harry ate half of the pizza therefore the fraction that Harry ate = 1/2 of 1

= 1/2 × 1 = 1/2

Therefore fraction Harry ate = 1/2

Fraction of pizza left = 1 - 1/2 (LCM = 2)

= 1/2

Jacqueline ate 1/2 of what was left.

So, Fraction of pizza Jacqueline ate = 1/2 × 1/2 = 1/4

Therefore fraction of pizza left after both Harry and Jacqueline ate =

1 - (1/2 +1/4) = 1 - 3/4 (LCM = 4) = 1/4

Therfore fraction of pizza left = 1/4

Stanley ate 1/2 of what was left.

So, fraction of pizza Stanley ate = 1/2 × 1/4 = 1/8

Therefore, fraction of pizza left after all three of them ate =

1 - (1/2 + 1/4 + 1/8) = 1 - 7/8 (LCM = 8) = 1/8

I hope this helps .......i know this is rlly confusing but i dont know how else to put it : )

Answer: z score is -19

Work Shown:

x = 22 is the raw score

mu = 60 is the mean

sigma = 2 is the standard deviation

z = (x-mu)/sigma = formula to find z scores

z = (22 - 60)/2

z = -38/2

z = -19

The z score of -19 means we are 19 standard deviations below the mean. Anything beyond 3 standard deviations is often considered unusual/rare as most of the data in the normal distribution is within 3 standard deviations (approximately 99.7% of the distribution)

13 miles x 5 miles = 65 square miles

Area of smaller rectangle on bottom:

3 miles x 7 miles = 21 square miles

65 + 21 = 86 square miles

Answer:

The answer is 86 square miles

To answer this, just do the quotient of the first one over the second one, and use the rules for quotient of exponential expressions of the same base:

[tex]\frac{6\,\,\,10^{-2}}{2\,\,\,10^{-8}} =\frac{6}{2} \,\frac{10^{-2}}{10^{-8}} =3\,\,\,10^{-2+8}=3\,\,\,10^6=3000000[/tex]

Answer:

1,788

Step-by-step explanation:

You calculate the volume of the cylinder minus the volume of the cube

[tex]volume = (\pi*r^2*height) - (width*lenght*height)\\ volume = (\pi*10^2*6) - (4*4*6) [yards]\\volume = 1,788[/tex]

The volume of solid in cubic yards is 1,788 cubic yards

What is the Volume of a Rectangle?

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

The radius of the solid = 10 yards

The height of the solid = 6 yards

The length of the box = 4 yards

The width of the box = 4 yards

Now ,

The volume of the solid = Volume of the cylinder - Volume of box

And ,

The Volume of cylinder = π x r² x h

The Volume of box = length x width x height

So , substituting the values in the equation , we get

Volume of Cylinder = π x r² x h

                                = ( 22/7 ) x 10 x 10 x 6

                                = ( 22/7 ) x 600

                                = 1884.95 yards³

Volume of the box = length x width x height

                               = 4 x 4 x 6

                               = 96 yards³

Therefore ,

The volume of the solid = Volume of Cylinder - Volume of the box

The volume of the solid = 1884 yards³ - 96 yards³

                                        = 1788 yards³

Hence , the volume of the solid is 1788 cubic yards
