Liz is using the distributive property to evaluate the expression 27 (36) by using friendlier numbers. Her work is shown below.

Liz’s Work


27(36)
Step 1
27 (3 + 12)
Step 2
27 (3) + 27 (12)
Step 3
81 + 324
Step 4
405

What was the first error that Liz made?
Step 1 should have been 27(6 + 30).
Step 2 should have been 27(3) + 12.
Step 3 should have been 27(30)(12).
Step 4 should have been 16,244.

“ Triangle A has side lengths 3,4 and 5 . Triangle B has side lengths 6,7 and 8 “

“1. Explain how you know that triangle B is not similar to triangle A”
“2. Give possible side lengths for triangle B so that it is similar to triangle A”

Answers

Answer/Step-by-step explanation:

A. Given that ∆A has side lengths 3, 4, and 5, that corresponds to the side lengths 6, 7, and 8 of ∆B, both ∆s can only be similar to each other if the ratios of their corresponding side lengths are equal.

Thus:

[tex] \frac{3}{6} [/tex] ≠ [tex] \frac{4}{7} [/tex] ≠ [tex] \frac{5}{8} [/tex] .

✅The ratio of their corresponding side lengths is not equal, therefore, triangle B is not similar to triangle A.

B. To get the possible side lengths for triangle B to make it similar to triangle A, simply multiply each side length of triangle A by a scale factor.

Let's use a scale factor of 2.

3 × 2 = 6

4 × 2 = 8

5 × 2 = 10.

✅Possible side lengths for triangle B that will make it similar to triangle A are: 6, 8, and 10.

since there are 5,280 feet in one mile and 3.3 feet in one meter how many meters per second are equivalent to 50 miles per hour

Answers

Given:

1 mile = 5280 feet

1 meter = 3.3 feet

convert 60 miles per hour to meters per second

60 miles to meters

60 miles x 5280ft x 1meter = (60*5280m)/3.3 = 316800m/3.3

                 1 mile    3.3ft

= 96,000 meters

1 hour to seconds

1 hour x 60 minutes x 60 seconds =   1 * 60 * 60sec = 3600 seconds

               1 hour            1 minute

unit rate: meters per second

96000 meters ÷ 3600 seconds = 26 2400/3600

simplify 26 2400/3600 ⇒ 26 2/3 meters per second

2400 ÷ 1200 = 2

3600 ÷ 1200 = 3

The measure of the supplement of ∠BAC is (18x+22) degrees. The measure of the complement of ∠BAC is (9x-5) degrees. Determine m∠BAC.

Answers

Answer:

∠ABC = 32°

Step-by-step explanation:

We know that the two angles are termed as supplementary when their angle measures add up to 180 degrees.

Given that the measure of the supplement of ∠BAC is (18x+22) degrees.

so

∠ABC +  (18x + 22)° =180°

∠ABC +  18x  =180°-22°

∠ABC +  18x  =158°

∠ABC = 158° - 18x ----[Equation A]

We know that the two angles are termed as complementary when their angle measures add up to 90 degrees.

Given that the measure of the complement of ∠BAC is (9x-5) degrees.

so

∠ABC +  (9x-5)° =90°

∠ABC +  9x  =90°+5°

∠ABC +  9x  =95°

∠ABC = 95° - 9x ----[Equation B]

Equating [Equation A] and [Equation B]

158° - 18x = 95° - 9x

-18x+9x = 95° - 158°

-9x = -63

divide both sides by -9

x = 7

Now, substituting the value x=7 in the [Equation A]

∠ABC = 158° - 18(7)

          = 158° - 126°

          = 32°

Thus,

∠ABC = 32°
