Answer:

$56.70

Step-by-step explanation:

The cost plus markup is found by multiplying $45 by 1.40:  $63.

With the 10% price reduction, the sale price is 0.90($63) = $56.70.

Regarding 1.40:  the '1' results in the full price to the manager plus the '0.40' markup.

photoshop1234 [79]
\frac{k}{13} = \frac{0.6}{0.5} equals k = 15.6

First,
simplify \frac{0.6}{0.5} to 1.2. Your problem should look like: \frac{k}{13} = 1.2
Second, multiply both sides by 13. Your problem should look like: k = 15.6, which is the answer.

The height of Atlas V rocket used for space lifts was 205 feet. What is the height of a model of Atlas V rocket if the scale fac
KengaRu [80]

Answer: 6.4 feet

Step-by-step explanation:

Height of Atlas V rocket = 205 feet

Ratio of the model = 1:32 = 1/32

Model / Real = 1/32

Since Real height = 205, we put it into the equation and this will be:

Model / Real = 1/32

Model / 205 = 1/32

Model × 32 = 205 × 1

Model = 205/32

Model = 6.4 feet

The height of the model is 6.4 feet.

Vladimir [108]

Answer:

30° =  m∠GFH

Step-by-step explanation:

Since ∠EFH and ∠GFH are complementary, the sum of their measures i 90.

Let x = m∠GFH

2x = m∠EFH

m∠GFH + m∠EFH = 90

x + 2x = 90

3x = 90

x = 30° =  m∠GFH

Solve the equation for a.
katrin [286]

Answer:

a= \frac{k}{9b+4}

Step-by-step explanation:

In this question, you would solve for "a".

Solve:

K = 4a + 9ab

Since we have our "a" on the same side, we can factor it out from the variables:

K = a(9b + 4)

To get "a" by itself, we would have to divide both sides by 9b + 4:

K/9b+ 4 = a

Your answer would be K/9b+ 4 = a

It would look like this: a= \frac{k}{9b+4}
