The answer to your question is distance = 3500000 km

Step-by-step explanation:

Data

Scale 1 : 500000

7 cm

Process

1.- To solve this problem use direct proportions or rule of three.

1 : 500 000 :: 7 : x

2.- Multiply the middle numbers and the result divide it by the edge.

x = (7 x 500000) / 1

Simplification

x = 3500000 km

The area (A) of a circle with a radius of r is given by the formula and its diameter (d) is given by . Arrange the equations in

ella [17]

Answer:

see explanation

Step-by-step explanation:

A = πr² ← r is the radius and r = $\frac{1}{2}$ d ← d is the diameter

Hence

π ( $\frac{1}{2}$ d)² = A, that is

$\frac{d^2\pi }{4}$ = A ( multiply both sides by 4 )

d²π = 4A ( divide both sides by π )

d² = $\frac{4A}{\pi }$ ( take the square root of both sides )

d = $\sqrt{\frac{4A}{\pi } }$

Peter works at Silly's and makes $33.19 an hour. He also collects a 5.3% commission on final weekly sales. Last month, he worked

Romashka-Z-Leto [24]

Answer:

$10,318.62

Step-by-step explanation:

We have been given that works at Silly's and makes $33.19 an hour. He also collects a 5.3% commission on final weekly sales. If he works over 40 hours during any week, he earns double his hourly wage.

Peter's hourly charges during 1st and 2nd week would be $33.19 and hourly charges during 3rd and 4th week would be 2 times $33.19.

First of all, we will find total hourly income as:

$\text{Total hourly income}=\$33.19(30+40)+2\times \$33.19(49+55)$

$\text{Total hourly income}=\$33.19(70)+\$66.38(104)$

$\text{Total hourly income}=\$2323.3+\$6903.52$

$\text{Total hourly income}=\$9226.82$

Now, we will find income from commission on sales as:

$\text{Income from commission on sales}=\frac{5.3}{100}(4500+5500+3800+6800)$

$\text{Income from commission on sales}=0.053(20600)$

$\text{Income from commission on sales}=1091.8$

Peter's total earnings is the last month: $\$9226.82+\$1091.8=\$10,318.62$

Therefore, Peter's total earnings in last month was $10,318.62.

The table represents the start of the division of 8x^4+2x^3-7x^2+3x-2 by the indicated divisor. Find the quotient.

zloy xaker [14]

Answer: 2x² + x - 2 (the first option)

Explanation:

1) Question: divide 8x⁴+2x³-7x²+3x-2 by 4x² - x + 1

2) First term of the quotient

 8x⁴ + 2x³ - 7x² + 3x - 2 | 4x² - x + 1
 ---------------------
-8x⁴ + 2x³ - 2x² 2x²
----------------------------------
 4x³ - 9x² + 3x - 2

3) Second term of the quotient:

 8x⁴ + 2x³ - 7x² + 3x - 2 | 4x² - x + 1
 ---------------------
-8x⁴ + 2x³ - 2x² 2x² + x
----------------------------------
 4x³ - 9x² + 3x - 2
 -4x³ + x² - x
 ----------------------------
 - 8x² + 2x - 2

4) third term of the quotient:

 8x⁴ + 2x³ - 7x² + 3x - 2 | 4x² - x + 1
 ---------------------
-8x⁴ + 2x³ - 2x² 2x² + x - 2
----------------------------------
 4x³ - 9x² + 3x - 2
 -4x³ + x² - x
 ----------------------------
 - 8x² + 2x - 2
 8x² - 2x + 2
 -------------------------
 0

5) Conclusion: since the remainder is 0, the division is exact and the quotient is 2x² + x - 2

You can verify the answer by multiplying the quotient obtained by the divisor. The result has to be the dividend.

Answer:

B or $12.50

Step-by-step explanation:

To get the answer, you have to solve x from the equation 4.5x = 56.25

To solve, you have to divide 4.5 from each side, making the equation look like,

x = 12.5

Hope this helps!!
