Answer:

Hello! answer: 12

Step-by-step explanation:

Assuming this is the Pythagorean theorem we would usually solve for c but c is already found so we have to work backwards so... 15 × 15 = 225

9 × 9 = 81 225 - 81 = 144 √144 = 12 therefore 12 is the answer Hope that helps!

Where did you get this question?

The number of cookies left, if Matt has 5 Cookies and Linn eats 3 of the cookies, is 2.

The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

Given:

The total number of cookies, t = 5,

The number of cookies Linn eats, n = 3,

Calculate the number of cookies left by using subtraction as shown below,

The number of left cookies = Total number of cookies - The number of cookies Linn eats

The number of left cookies = t - n

The number of left cookies = 5 - 3

The number of left cookies = 2

Thus, the number of cookies left is 2.

The correct option is option B that is [tex]\frac{-9}{10}[/tex] is the same number as Callie has written to show the change in volume.

What is a fraction ?

A fraction is used to represent a portion or component of a whole. The numerator and denominator are its two parts.

It is given that Callie wrote a number to show the change in volume of a water cooler after practice which is :

= [tex]\frac{-9}{10}[/tex]

Let's check from the given options which is the correct one.

A)

- [tex]\frac{9}{-10}[/tex]

if we multiply and divide by -1 then we find that the given fraction is equal to :

= [tex]\frac{9}{10}[/tex]

This is not equal to what Callie has written.

B)

[tex]\frac{-9}{10}[/tex] is the same number as Callie has written to show the change in volume. So , this is a correct option.

C)

[tex]\frac{-9}{-10}[/tex] will be equal to [tex]\frac{9}{10}[/tex]. This is because there is negative sign in both numerator and denominator of the fraction , and they will get cancelled. So, this option is not correct.

D)

[tex]\frac{9}{10}[/tex] is not equal to [tex]\frac{-9}{10}[/tex]. To equal both we need to multiply [tex]\frac{9}{10}[/tex] by -1. Thus this option is also not correct.

Therefore , the correct option is option B that is [tex]\frac{-9}{10}[/tex] is the same number as Callie has written to show the change in volume.

Step-by-step explanation:

Answer:

D) y-7=-6/11(x+7)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(1-7)/(4-(-7))

m=-6/(4+7)

m=-6/11

y-y1=m(x-x1)

y-7=-6/11(x-(-7))

y-7=-6/11(x+7)

y=-6/11x-42/11+7

y=-6/11x-42/11+77/11

y=-6/11x+35/11

Answer:

81/792 or 9/88 or 10.2%

Step-by-step explanation:

Possibility: nCr(12,5) = 792
Red: nCr(3,2) = 3
Blue, Green, White: nCr(3,1) = 3

3 * 3 * 3 * 3 = 81

81/792 simplified is 9/88 percentage is 10.22%

The probability that Jamal will catch 2 red balls and 1 ball of each of the other colors is 0.1025.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lies in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The total numbers of balls are 12.

Each color has 3 balls.

If total 12 balls are tossed, the number of ways of catching 5 of them is,

¹²C₅ = 792

The number of ways of catching 2 red balls out of 3 is ³C₂ = 3

The number of ways of catching 1 green ball out of 3 is ³C₁ = 3

The number of ways of catching 1 blue ball out of 3 is ³C₁ = 3

The number of ways of catching 1 white ball out of 3 is ³C₁ = 3

Thus, the probability as per the question is given as follows,

(3 × 3 × 3 × 3)/792

= 81/792

= 0.1025

Hence, the probability of catching 2 red balls and 1 ball of each of the other colors is 0.1025.

Answer:

10 feet

Step-by-step explanation:

Salvador has a rug in his bedroom with perimeter of 36 feet, the length of the rug is 8 feet what is the width of the rug?

The rug is shaped as a rectangle

The formula for the Perimeter of a rectangle = 2L + 2W

Perimeter = 36 feet

Length = 8 feet

Hence

36 = 2(8) + 2W

36 = 16 + 2W

2W = 36 - 16

2W = 20

W = 20/2

W = 10 feet

Therefore, the Width of the rug is 10 feet

Answer:

500π m^3

Step-by-step explanation:

The question is not complete

Cylinders are described with dimensions as

Diameter and Height

Say the diameter is

D= 10m

and Height is

H=20

Hence the radius is

R= D/2= 10/2= 5 m

Therefore the volume is gotten as

V= πr^2h

V= π*5^2* 20

V=  π*25*20

V= 500π m^3

Hence the volume is  500π m^3

Answer:

O $225.00

Step-by-step explanation:

Given that

The one of the flight was 350 miles

And, its residual is 105

The regression line is y = 102.50 + 0.65x

where

y denotes the expected fare

And, x denotes the distance

We need to find out the fair of the flight

So,

y = 102.50 + 0.65 (350)

= 330.00

Now the fare is

= 330 - 105

= 225

Answer:

(C) 225 Is correct.

Predicted cost - residual = answer

y= 102.50 + .65(35)

330 - 105 = 225

Answer:

B. (2x + 10)(2x + 9)

Step-by-step explanation:

Length (L) of the garden and walkway = x + 10 + x = (2x + 10) ft

Width (W) of the garden and walkway = x + 9 + x = (2x + 9)

Area of the garden and walkway = area of rectangle = L*W

= (2x + 10)(2x + 9)

The polynomial representing the total area of the garden and walkway = (2x + 10)(2x + 9)

Let x = 10 in

y = 10 in

z = 9 in
