Natalija [7]

Answer:

Step-by-step explanation:

1. Use the Pythagorean theorom: a^2+b^2=c^2.

C is the missing side here, which is the hypotenuse of the triangle. The other two sides and be put into the equation either way. Doesn't matter the order.

15^2 + 36^2 =c^2

2. Evaluate 15^2 and 36^2 and add the results.

15^2 = 225

36^2 = 1,296

225+1,296= 1,521

3. Take the square root of the answer.

√1521 = 39

Eric’s average income for the first 4 months of the year is $1,450.25, what must be his

Mandarinka [93]

Answer:

$1946

Step-by-step explanation:

Eric’s average income for the first 4 months of the year is $1,450.25

Therefore, his total earning in the first four months

= 4 X $1,450.25

=$5,801

Let the average income for the remaining 8 months= x

Then:

$\text{Eric's Yearly Average Income}=\dfrac{5801+8x}{12} \\1,780.75=\dfrac{5801+8x}{12} \\$Cross multiply\\12*1,780.75=5801+8x\\21369=5801+8x\\8x=21369-5801\\8x=15568\\Divide both sides by 8\\x=\$1946$
