Answer:
-15/16
Step-by-step explanation:
The sum of a geometric series with first term a1 is ...
S = a1/(1 -r)
Then the common ratio (r) is ...
r = 1 -a1/S
For the given values, the ratio is ...
r = 1 - 124/64 = -15/16
The common ratio is -15/16.

Here, (w) is the width, (h) is the height and (l) is the length of the prism.
Becca is painting a birdhouse. The shape of the birdhouse is similar to rectangular prism with dimensions as, height of 13cm, a width of 5 cm, and a length of 8cm.
Now Becca wants to paint this house using 1 coat. As this paint has to be cover each surface of the house. Thus the amount of total paint should be equal to the surface area of the house.
Here, the dimensions of house is as, height of 13cm, a width of 5 cm, and a length of 8cm. Therefore the surface area of it is,
[tex]SA=2(5\times8+13\times8+13\times5)\\SA=418\rm cm^2[/tex]
Hence, the amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².

Mary bought more than 72 pencils to distribute to children at an orphanage. She packs these pencils in gift boxes.
If she packs 4 pencils each into x gift boxes, the inequality that represents this situation is
.
The simplified form of the inequality is
Answer:
4x≥=72
Step-by-step explanation:
1. Particularly, we have:
Given:
X: number of gift boxes
2. We then have to write the inequation that models the problem:
"Mary bought more than 72 pencils"
"She packs 4 pencils each into x gift boxes"
Finally we have:
4x≥=72, for the inequality that represent this situation.
When Simplfying (simplified form):
= x≥72/4
= x≥18
Answer:
4x > 72
x > 18

8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13

find the value of x and please show how
Answer:
x = 12°
Step-by-step explanation:
The sum of angles in a triangle is 180°.
So,
39° + 53° + 4° + 7x = 180°
Add all the numbers on the left up.
96° + 7x = 180°
Subtract 96 from both sides.
7x = 84°
x = 12°
Hope this helps!
Answer: x= 12
Step-by-step explanation:
Triangle angle sum theorem says that the interior angles of a triangle sum to 180 degrees. Set the sum of all of these angles equal to 180 to solve. 39+53+ (4+7x) = 180. Combine like terms. 96 +7x = 180. Subtract 96 from both sides. 7x = 84. Divide both sides by 7. X = 12
PLEASE HELP QUICKLY!!
Answer:
79
Step-by-step explanation:
Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.
