Angle FEG is similar to triangle IHJ. Find the value of X.

Mathematics

Oliga [24]3 years ago

Answer:

x = 14.8

Step-by-step explanation:

As these triangles are similar, every side and angle corresponds and this is key to calculating this equation.

First, look at the side that is labeled x + 8 and find the corresponding side on the other triangle. Write this out as a fraction as shown below. Now find two corresponding sides that are both marked (the base lines) and write them out as a fraction as well (note that which ever triangle you are solving for, it's numbers will go on the top of the fraction)

\frac{x + 8}{36} = \frac{38}{60}

We want to get the x by its self and at the moment it is divided by 36. To remove the 36, we need to multiply both sides of the equation by 36

36 x \frac{x + 8}{36} = \frac{38}{60} x 36

This cancels out both the 36s on the left leaving us with

x + 8 = \frac{38}{60} x 36

all that needs to happen now is to remove the +8 so we are just left with x. to do this, just subtract 8 from both sides and we are left with

x = \frac{38}{60} x 36 - 8

calculate 38 ÷ 60 x 36 - 8 = 14.8

∴ x = 14.8

I hope this was helpful and not too long :-)

Hi there! :)

<h2>20%</h2><h2></h2>

To solve, we can simply divide and multiply by 100 to solve for the percentage:

5 / 25     = 5 ÷ 25 = 1/5 or 0.20

Multiply the decimal by 100 to solve for the percentage:

0.20 × 100 = 20%

WHUR Radio uses 1/5 of its of its 10 hours of daytime broadcast for commercial and 1/2 for music. How much is left for news?
Nataly [62]

Answer: 3 hours

Step-by-step explanation:

From the question, we are informed that WHUR Radio uses 1/5 of its of its 10 hours of daytime broadcast for commercial and 1/2 for music.

Hours used for commercial:

= 1/5 × 10

= 2 hours

Hours used for music:

= 1/2 × 10

= 5 hours

Hours left for news will be:

= 10 hours - 2 hours - 5 hours

= 3 hours

1 1/3 divided by 2 5/6
victus00 [196]
The answer is 8/17 because you have to change the fractions to improper fractions then change the division sign to a multiplication sign. Then change the second fraction by flipping the two numbers then multiply and reduce.

A flower shop acquired 80 new customers last year. Costs in the marketing and sales areas were the following:
icang [17]

Using proportions, it is found that the Customer Acquisition Cost was of $1,215.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

In this problem, the customer acquisition cost is the spending in sales divided by the number of customers added.

80 customers were added, considering costs of 1200 + 9000 + 87000 = $97,200, hence:

97200/80 = $1,215.
