Sarah walks to school, 1.5 miles in 30 minutes. what is the snswer to this
nevsk [136]

Answer: 3 mi/h

Step-by-step explanation:

Here we have to find the speed V at which Sarah walks to school, knowing the distance d she has walked and the time t she expends.

So, in this case we can use the following equation:

V=\frac{d}{t}

Where:

d=1.5 mi

t=30 min \frac{1 h}{60 min}=0.5 h

Solving:

V=\frac{1.5 mi}{0.5 h}

V=3 mi/h This is Sarah's speed

Given ABC = DEF and the perimeter of DEF =38, find BC
ddd [48]

Answer: BC = 15

Step-by-step explanation:

Since the triangles are congruent, that means they are the same. So side AB = side EF. Since we know side FD is 15, that means side BC= 15

A and B are similar solid cylinders base area of A : base area of B = 9 : 25
fomenos

Answer:

Two figures are similar if the figures have the same shape but different sizes.

Then if we have two figures X and X'

Such that one dimension of X is D, the correspondent dimension on X' will be:

D' = k*D

Such that k is the scale factor that relates the figures.

1:k

Because all the dimensions will be rescaled by the same scale factor k, we can conclude that any surface on X will be related to the same surface in X' by:

S' = k^2*S

then the ratio of the surfaces is:

1:k^2

While the relation between the volumes will be:

V' = k^3*V

Here the ratio is:

1:k^3

Ok, in this case we have two cylinders

We know that the ratio between the base area ( a surface) is:

9:25

a) We want to find the ratio: curved surface area of A : curved surface area of B

Because again we have a surface area, the ratio should be exactly the same as before, 9:25

b) height of A : height of B

In this case, we have a single dimension.

Because in the rescaling of a surface we need to use k^2, then we can conclude that the ratios:

9:25

is related to k^2

Then the ratio, in this case, is given by applying the square root to both sides of the previous ratio, so we get:

√9:√25

3:5

This is the ratio of the heights.

Also from this we could get the value of k, that is the right value when we leave the left value equal to 1, we can get that if we divide both sides by 3.

(3/3):(5/3)

1:(5/3)

Then:

k = 5/3
