Answer:

x = 82.35

Step-by-step explanation:

42/51 = x/100

cross multiply, then you get

42*100 = 51*x

4200/51 = 51x/51

x = 82.35

Solve (x + 2 < 5) ∩ (x - 7 > -6).

garri49 [273]

Let $A=x+2\lt5, B=x-7\gt6$ .

Simplifying both you get $A=x\lt3,B=x\gt1$ .

The set conjunction is $A\cap B=1\lt x\lt3$ .

So the answer is B.

Hope this helps.

A rate that describes how much smaller or larger the scale drawing is than then real object

Tems11 [23]

I'm not sure what is being asked here, but a rate that describes how much smaller or larger the scale drawing is than the real object would be a ratio such as 1in:25ft

Mrs. Sloan draws two figures on the board.

Trava [24]

A dilated shape will either be enlarged or compressed.

<em>Allen did not make any mistake, and the scale factor is 3.</em>

The dimension of the smaller rectangle (figure Z) is:

3 units by 4 units

The corresponding dimension of the bigger rectangle (figure Z') is:

9 units by 12 units

The scale factor (k) is calculated by dividing the dimensions of Z' by Z.

So, we have:

$k = \frac{9}{3}$

$k = 3$

$k = \frac{12}{4}$

$k = 3$

Notice that both values of k are the same (i.e. 3)

This means that the scale factor is 3

Also figure Z and Z' share the same center of origin at point X

This means that the center of dilation from Z to Z' is X

Hence,

Allen made no mistake, and she is correct about the scale factor.
