Base = 5 * 12 = 60 in^2

Height = 4 in

Perimeter is the sum of all straight

Perimeter = 20 + 16 + 48

Perimeter = 84 in

Perimeter of base = 12 * 2 + 5 * 2 = 34

there are 5 times as many yellow labs as terriers in the dog park. if there are a totsl of 18 dogs , how many dogs are terriers?
PSYCHO15rus [73]
So,

There are 5 times as many yellow labs (call them y) as terriers (call them t).
5t = y

There are 18 dogs total.
t + y = 18

Substitute 5t for y in the second equation.
t + 5t = 18
6t = 18

Divide both sides by 6.
t = 3

There are three terriers and 15 yellow labs.

So the system of equations would be:
5t = y
t + y = 18

As for the model, you can have a circle represent the number of terriers.  Since there are 5 times as many yellow labs as terriers, you will have to have five more circles.  Adding them up, you will have 6 of the circles, or 6 times circle.  The total is 18, so 6 of the circles is 18.  6 times what is 18?  3.  Therefore the circle, and therefore the number of terriers, is 3.

If a spherical ball is enlarged so that its surface area is 9 times greater than its original surface area, then the original ra
luda_lava [24]
The surface area of a sphere is A = 4 \pi r^{2} and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0. 

For example, let us assign values.
Let A=90

A= 90*9 = 810

90 = 4 \pi   r^{2} 

    and    810 = 4 \pi  r ^{2}

the first r is 2.68 and the second r is 8.03

then, \frac{8.03}{2.68} = 2.99626  or rounded off to 3.

Answer:

{2, 4, 6}

Step-by-step explanation:

the domain is the interval or set of valid x (input) values.

the range is the interval or set of valid y (result) values.

just use the x values in the functional definition and collect the results. these are the range.

x = -1

y = 2×-1 + 4 = 2

x = 0

y = 2×0 + 4 = 4

x = 1

y = 2×1 + 4 = 6
