Please help! Triangle ABC is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. Which statement describes the properties of triangles ABC and A''B''C'' after the transformations?A) ∠C and ∠C'' are congruent after both the translation and the dilation.
B) ∠C and ∠C'' are congruent after the dilation, but not after the translation.
C) segment AC and segment A double prime C double prime are congruent after both the translation and the dilation.
D) segment AC and segment A double prime C double prime are congruent after the dilation, but not after the translation.

Answers

Answer:

Step-by-step explanation:

1) Translated figures are congruent ones, so $\bigtriangleup ABC\cong \bigtriangleup A'B'C'$ , one unit to the right and one up in comparison to $\bigtriangleup ABC\cong \bigtriangleup ABC$ .

2)Since $\bigtriangleup A''B''C''$ was dilated with a scale factor of two then It's a similar figure to $\bigtriangleup ABC$ . Similar figures have congruent angles and different sizes.

Hence, ∠C≅∠C"

Which expressions result in a negative number? Choose all answers that are correct. A. –84 ÷ 21 B. C. –7.3 – (–4.3) D. –4.2 • (–3.5)

Answers

A and B, when dividing the two numbers for A, the answer is negative 4. And as for B, the answer comes out to negative 3 I believe.

A and B. Because -84:21= -4 and (-and -=+) so -7.3+4.3=-3

Find the volume of the composite figure. please!

Answers

the volume is 300 inches cubed, first I split the figure into three, the volume=L×W×H, for the first box I did 4×4×5=80, the second box I did 6×6×5=180, the third box I did 2×4×5=40, therefore 80+180+40=300 therefore the answer being 300 inches cubed

Put these in order starting from the smallest.The first one is done for you.
0.72
0.799

Answers

Answer:

Step-by-step explanation:

You'll find it easier to do this problem if you'd first rewrite the numbers so that they're all in the same numerical format:

A: 3/4 = 0.75

B: 0.72 = 0.72

C: 4/5 = 0.80

D: 0.799 = 0.799

E: 9/10 = 0.90

Now it's easy to see that B: 0.72 is the smallest of the 5 numbers and that 0.90 is the largest.

Arranged in ascending order, we have 0.72, 0.75, 0.799, 0.80, 0.90
