I would choose a because when you put in the calculator 9 divided by 40 you get 0.225.

I would choose E) because 15 divided by 64 is about 0.23, which is the closest to 0.25

Answer: 2.5, 17.5

Step-by-step explanation: I'm kinda confused at what those big blue things with numbers are... but im guessing that's just used to indicate the missing values. So 10/4 = 2.5, meaning the ration is 2.5 pounds per week. So 1 week is 2.5 pounds, and 7 weeks is 2.5*7 = 17.5

For ΔABC, ∠A = 3x - 8, ∠B = 5x - 6, and ∠C = 4x + 2. If ΔABC undergoes a dilation by a scale factor of 1/2 to create ΔA'B'C' wit
Snezhnost [94]

Answer:

D. ∠B = ∠B' = 74° and ∠C = ∠C' = 66°

Step-by-step explanation:

Given,

\angle A=3x-8\\\angle B=5x-6\\\angle C=4x+2

We know,sum of all 3 angles of a triangle is 180°

Doing so ,

\angle A+\angle B+\angle C=180\\3x-8+5x-6+4x+2=180

Simplifying all like terms,

12x-12=180\\12x-12+12=180+12\\12x=192

Dividing both side by 12

x=\frac{192}{12}

x=16

Now we plug this in each angles and find their exact values.

\angle A=3x-8=(3\times16)-8=48-8=40°

\angle B=5x-6=(5\times16)-6=80-6 =74°

\angle C=4x+2 = (4\times16)+2=64+2=66°

Now substituting the x=16 in angles of dilated triangle.

\angle A'=(2\times16)+8=32+8= 40°

\angle B'=90-16=74°

\angle C'=(5\times16)-14=80-14=66°

We see that all the corresponding angles are equal and as far as the options are concerned only option (D) matches.
