Answer:

x=7

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

Triangles JKL and MNP are similar by AA Similarity Theorem

so

Remember that

If two figures are similar then the ratio of its corresponding sides is proportional

so

\frac{JK}{MN}=\frac{JL}{MP}

substitute the given values

\frac{25}{30}=\frac{20}{4x-4}

solve for x

Simplify

4x-4=\frac{30}{25}(20)

4x-4=24

4x=24+4

4x=28

x=7

Ankit deposits $800 in an account that earns 6% yearly interest compounded monthly. How much will the account be worth
Aleks [24]

Answer:

the compounded monthly formula is

total = principal * ( 1 + (rate / 12)) ^ 12*2 years

total = $800.00 * (1  + .06 / 12) ^ 24

total = $800.00 * (1.005) ^ 24

total = $800.00 * 1.1271597762

total = $901.7278209643

total = 901.73 (rounded)

A car dealership has SUVs and sedans in a ration of 5:9. How many sedans does the car dealership have if there are 140 SUVs
Elza [17]

To solve this, all you need to do is compare the ratio to the amount of SUVS there are.

5/9 (SUVs to sedans)

140/? (SUVs to sedans)

140 ÷ 5 = 28

9 x 28 = 252

140/252

There are 252 sedans in the car dealership! :D
