find 3 numbers in GP whose sum is 28 and product is 512
Answer:
4,8 and 16Let the three numbers be a,ar, ar^2 ,
where r is the common ratio.
⇒a+ar+ar^2 =28 and a^3 r^3 =512
⇒ar=8⇒a+ar^2 =20
⇒8r^2 −20r+8=0
⇒r=2,r= 1/2
If r=2,a=4
Therefore, the three numbers are 4,8,16.

A school club wants to collect at least 500 canned goods for a school food drive. The club has already collected 30 canned goods.
If 10 club members each collect the same number of canned goods, which inequality and graph represent the minimum number of canned goods, n, each club member must collect for the club to meet the goal? (HOW DID YOU GET YOUR ANSWER, PLEASE SHOW ME YOUR WORK!!)
A. 10n+30<500
B. 10n+30≥500
C. 30n+10≤500
D. 30n+10>500
Answer:
The correct answer is 10n ≥ 470.
Step-by-step explanation:
Since, the school club wants to collect at least 500 canned goods, then we know that they don't want to collect any less: they must collet 500 or more canned goods.
They already collected 30 canned goods, therefore we can subtract this quantity from out goal.
500 - 30 = 470
Since there are 10 club members, the number of members multiplied by "n" the minimum amount of canned goods that they can collect, will equal the total amount of canned goods that they need.

1. Find the equation of the line that passes through the point
(2,12) and is parallel to the equation below.
y = 40 - 1
A. y = 43 – 20
B.y = 45 + 4
C. y = + 14
D.y = x + 10
Answer:
None of the above ? （the equation should be y=12）
Step-by-step explanation:
the line parallel to line y=40-1=39 means it's a horizontal line. Which means it's y coordinate is also a constant. Since it pass through （2,12）,it means the constant of y is 12.

Diego and Jada are both trying to write an expression with fewer terms that is equivalent to
7a+5b−3a+4b
Jada thinks 10a+1b is equivalent to the original expression.
Diego thinks 4a+9b is equivalent to the original expression.
Substitute your own values for “a” and “b” and determine if the expressions are equivalent. Show your work in the space provided.
Answer:
Diego's answer 4b+9b is correct:)
Step-by-step explanation:
Our first step is to combine like terms.
Causing you to combine 7a and -3a which gives you 4a because 7-3=4
Next, you would combine 5b and 4b which gives you 9b because 5+4=9
After you have combined like terms you would have your simplified equation 4b+9b causing Diego's answer to be correct!
Hope this helps!

The length of a rectangle is 13 centimeters less than its width. What are the dimensions of the rectangle if its area is 140 square centimeters?
Answer:
Dimensions = 7 cm by 20 cm.
Step-by-step explanation:
Let the length and width of the rectangle be L & W respectively.
Given the following data;
Area of rectangle = 140 cm²
L = W - 13
To find the dimensions of the rectangle;
The area of rectangle = L * W
Substituting into the above formula, we have;
140 = L * W
140 = (W - 13) * W
140 = W² - 13W
W² - 13W - 140 = 0
Solving the quadratic equation using factorization method;
Factors are -20 and 7
W² - 20W + 7W - 140 = 0
W(W - 20) + 7(W - 20) = 0
(W - 20)(W + 7) = 0
W - 20 = 0
W = 20
W + 7 = 0
W = -7
Thus, W = 20 or -7
But the width has to be positive, W = 20 centimeters.
Next, to find the length of rectangle
L = W - 13
L = 20 - 13
L = 7 centimeters.

Last week at the park Haeather ran 4 miles in 48 minutes when she runs her next race she Hope's to improve her time by 2 minutes per mile
Last week at the park what was haeather rate of speed in miles per hour
Answer:
Haeather ran at a speed of 5 miles per hour.
Step-by-step explanation:
Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:
48/4 = 12
Thus, Haeather ran 1 mile every 12 minutes.
60/12 = 5
1 x 5 = 5
Therefore, Haeather ran at a speed of 5 miles per hour.

What is the total interior measure of the polygon?
And what’s the value of x?
Answer:
x =196°
Step-by-step explanation:
The polygon is 5 sided, therefore, total interior angles of a pentagon is:
(n - 2) 180
(5 - 2) 180
(3) 180
540°
96° + 112° + 102° + 84° + x° = 540°
394° + x = 540°
Collect like terms
x = 540° - 394°
x = 196°

Answer:
= 20 square units
Step-by-step explanation:
First we calculate the obvious square without the extra points. The side length of the square is four; therefore, the area of the square is 16 square units. The points are each 1 square unit as they split the squares down the midde. In total, 16 + 4(1) = 20.
