Ahmed found the volume of a cone having both a height and a diameter of 6 centimeters. His work is shown below.What was Ahmed’s first error?
In Step 1, the radius should be found by multiplying the diameter by 2.
In Step 2, the formula 2pi r should be used to find the area of the circle.
In Step 3, the resulting area should be in terms of pi
In Step 4, the units of the resulting volume should be cm^2

Answers

Answer 1
Answer:

Whenever we are given with the diameter of any such figure ,

to find the radius , we divide the diameter by 2.

We know that

Diameter = 2 * radius

or

Radius = Diameter /2

,

In the question it says the in first step that

the radius should be found by multiplying the diameter by 2

, this is the first error

It should be that

the radius should be found by dividing the diameter by 2

Ed can run 10 miles in 2 hours at a steady rate . how many hours will it take him to run 30 miles ?

Answers

Answer:


Step-by-step explanation:

It should take six hours.

Ten times three would make thirty, doing the same to the number of hours[2 hours] we multiply it by three which leaves us with six miles.

Ed runs thirty miles in six hours.

Answer:

6 hours

10 miles takes 2 hours

so 30 miles will take 6 hours


Solve for L: S=2WL+2LH+2WH

Answers

Answer:

Step-by-step explanation:

S = 2WL + 2LH + 2WH

S - 2WH = 2WL + 2LH

S - 2WH = L(2W + 2H)

(S - 2WH) / (2W + 2H) = L <===

Select all functions that have a y-intercept of (0,5).f(x)=7(b)^x-2
f(x)=-3(b)^x-5
f(x)=5(b)^x-1
f(x)=-5(b)^x+10
f(x)=2(b)^x+5

Answers

Answer:

f(x)=7(b)^(x)-2

f(x)=-5(b)^(x)+10

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

Verify each case

case 1) we have

f(x)=7(b)^(x)-2

so

For x=0

f(0)=7(b)^(0)-2

f(0)=7(1)-2=5

therefore

The function has a y-intercept of (0,5)

case 2) we have

f(x)=3(b)^(x)-5

so

For x=0

f(0)=3(b)^(0)-5

f(0)=3(1)-5=-2

therefore

The function does not have a y-intercept of (0,5)

case 3) we have

f(x)=5(b)^(x)-1

so

For x=0

f(0)=5(b)^(0)-1

f(0)=5(1)-1=4

therefore

The function does not have a y-intercept of (0,5)

case 4) we have

f(x)=-5(b)^(x)+10

so

For x=0

f(0)=-5(b)^(0)+10

f(0)=-5(1)+10=5

therefore

The function has a y-intercept of (0,5)

case 5) we have

f(x)=2(b)^(x)+5

so

For x=0

f(0)=2(b)^(0)+5

f(0)=2(1)+5=7

therefore

The function does not have a y-intercept of (0,5)

Answers

y=dependent variable
x=independent variable.

y=number of T-shirt
x=number of tickets.

The function would be:
y=x/15

Therefore:
T-shirt= dependent variable.
tickets=independent variable.
