The two triangles (ABC and ADE) can be shown to be similar (which I'll do below). Their corresponding parts are also similar.
Step One
Prove Similarity.
A is common to both triangles Construction
<ABC = <ADE Given as right angles.

By the AA Theorem both triangles are similar.

Step Two
Find x

AD is to AB as DE is to x
AD = 3 + 4 = 7
AB = 3
DE = 6
7 / 3 = 6/x Cross multiply
7x = 3 * 6
7x = 18 Divide by 7
x = 18/7
x = 2.571 <<<<< answer

A container has peppermint gum and spearmint gum. There are 40 pieces of peppermint gum in the container and the ratio of pepper

Anit [1.1K]

Answer:

16 pieces of spearmint gum

Step-by-step explanation:

For every five pieces of peppermint gum, there are 2 pieces of spearmint gum.

First, divide the total number of peppermint gum by 5:

40/5 = 8

Multiply this number by 2 (pieces of spearmint) to get the number of spearmint gum pieces:

8 x 2 = 16

Proof:

Ratio is 40 : 16, dividing this by 8 will reduce the ratio to 5:2

Which representation has a constant of variation of -2.5

Neporo4naja [7]

Answer:

See explanation

Step-by-step explanation:

The constant of variation is found using the slope formula:

$\frac{y_2-y_1}{x_2-x_1}$

The given relation is

X : -2 , -3, -4, -5

Y : -5, -7.5,-10,-12.5

We can use any two ordered pair to find the constant of variation.

Using (-2,-5) and (-3,-7.5), we have

$m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5$

The constant of variation is 2.5

We need to repeat this for all the options to identify the one with -2.5 as slope.

unfortunately, you did not provide the remaining options.
