we conclude that the height of the triangle measures 12 centimeters.

<h3>How to find the height of the triangle?</h3>

We know that the area of a triangle is given by the formula:

A = b*h/2

We can solve that equation for h, so we get:

h = 2*A/b

Now, we know that the area is 90cm^2, and the base measures 15 cm, replacing these two values we can get:

h = 2*(90cm^2)/15cm =  12cm

In this way, we conclude that the height of the triangle measures 12 centimeters.

Vanessa earns a base salary of $400 every week with an additional 5% commission on everything she sells. Vanessa sold $1850 wort
lys-0071 [83]

Answer:

$492.50

Step-by-step explanation:

To start off, we already know that Vanessa makes at least $400 every week. What we don't know is how much Vanessa makes from her 5% commission on what she sells.

To solve for that, we need to find what 5% of $1,850 is. This can be done by multiplying $1,850 by 5%. Remember, we need to change 5% into its decimal form (5% -> \frac{5}{100} -> 0.05).

$1,850 x 0.05 = $92.5

This means that Vanessa made $92.5 off of commissions last week. The last step is to add her base salary of $400 to her commission sales and we get our final answer.

$400 + $92.5 = $492.50

Vanessa's total pay last week was $492.50

Directions: Solve the following by multiplying by the inverse of the fractional coefficient. 1. \frac{2}{5} t = 20 2. \frac{7}{8
coldgirl [10]

The answer of the following options are as 50, 64, 36, 40, 100, 9, 12, 12 100, 27, 150 42, 50 72, 28.3.

<h3>How to interpret the fraction?</h3>

Suppose the fraction is proper (the numerator is smaller than the denominator).

Let it be

\dfrac{a}{b}

Then, we can interpret it as:

a parts out of b parts of a thing.

1. \dfrac{2}{5} t = 20\\\\t = 20 \times \dfrac{5}{2}\\\\t= 50

2. \frac{7}{8} p = 56\\\\p = 56 \times \frac{8}{7} \\\\ p= 64

3. \frac{5}{6} x = 30 \\\\x = 30 \times \frac{6}{5}  = 36

4. \frac{1}{2} x = 20\\\\x = 20 \times 2 = 40

5. \frac{3}{5} s = 60\\\\s = 60 \times \frac{5}{3} = 100

6. \frac{1}{3} t = 3 \\\\t = 3\times 3 = 9

7. \frac{3}{4} x = 9\\\\x = 12

8. \frac{11}{12} x = 11\\\\x = 11 \times 12/11 = 12

9. \frac{8}{10} t = 80\\\\t = 80 \times 10/8 = 100

10. \frac{p}{3} = 9 \\\\p = 9 \times 3 = 27

11. \frac{n}{5} = 30\\\\n = 30 \times 5 = 150

12. \frac{6a}{7} = 36 \\\\a = 36 \times 7/6 = 42

13. \frac{1}{2} t + 3 = 28\\\\t = (28 - 3)2 = 50

14. \frac{1}{6} r = 12\\\\r = 12\times 6 = 72

15. \frac{11}{12} b = 32\\ \\b = 32 \times 11/12 = 29.33
