Answer:

A = 90.25π

r = 9.5

A = 90.25π

Mashcka [7]

Answer:

A; ?; Line 3

Step-by-step explanation:

Question 1:

-30 divided by -6 is 5.

The negatives cancel each other out.

And 30 divided by 6 is simply 5.

Question 2:

$62\div(3+9)$

Do the operation inside the parenthesis first:

$62\div12$

Divide. 12 does not go into 62 evenly. 12 times 5 is 60, so the answer is 5 remainder 2:

$62\div12=5\text { R}2$

Or in fractions:

$31/6$

(Was there a typo? From what you've given me, the correct answer is not listed.)

Question 3:

So we have to following steps:

$\text{Line 1: } 21+35\div7+6(2)\\\text{Line 2: }21+5+6(2)\\\text{Line 3: }21+11(2)\\\text{Line 4: }21+22\\\text{Line 5: }43$

The mistake is in Line 3. Danny cannot just combine 5+6(2) into 11(2). Instead, he should multiply 6(2) and then add. Thus, the correct solution is:

$\text{Line 1: } 21+35\div7+6(2)\\\text{Line 2: }21+5+6(2)\\\text{Line 3: }21+5+12\\\text{Line 4: }26+12\\\text{Line 5: }38$

Answer:

A. △BDC∼△EDA

Step-by-step explanation:

Corresponding angles are:

∠A ≅ ∠C
∠D ≅ ∠D
∠B ≅ ∠E

Use same order of corresponding vertices in the name of triangles.

Choices are:

△BDC∼△EDA, correct
△BCD∼△EDA, incorrect should be △BCD∼△EAD
△EAD∼△BDC, incorrect should be △EAD∼△BCD
