Answer:
RS = 47 units
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
3x + 5 = [tex]\frac{1}{2}[/tex] ( 2x + 15 + 6x - 37)
3x + 5 = [tex]\frac{1}{2}[/tex] (8x - 22) = 4x - 11 ( subtract 4x from both sides )
- x + 5 = - 11 ( subtract 5 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
Thus
RS = 2x + 15 = 2(16) + 15 = 32 + 15 = 47

Mr. JB has a rectangular lot that measures 550 meters by 550 km. What is the area of the land in square meter. He i selling the whole lot for 206,250,000 pesos how much is the price per square meter?
Answers
9514 1404 393
Answer:
15/22 peso/m^2 ≈ 0.68182 peso/m^2
Step-by-step explanation:
The area is the product of the dimensions. 1 km = 1000 m.
A = (550 m)(550·1000 m) = 302,500,000 m^2
The price per square meter is ...
206,250,000/302,500,000 peso/m^2
= 15/22 peso/m^2 ≈ 0.68182 peso/m^2
what value of x makes this statement true?
3x=2x+12
A) 2
B) 5
C) 6
D) 12
Answers
Answer:
The value of x = 12, makes the statement [tex]3x=2x+12[/tex] true
Option D is correct option.
Step-by-step explanation:
What value of x makes this statement true?
[tex]3x=2x+12[/tex]
We need to solve the equation to find value of x
[tex]3x=2x+12[/tex]
Subtract 2x on both sides
[tex]3x-2x=2x+12-2x\\x=12[/tex]
So, the value of x is: x=12
So, The value of x = 12, makes the statement [tex]3x=2x+12[/tex] true
Option D is correct option.

A linear function follows a constant rate of change Here we see x moves by 4 units and that y decreases by 4 units then suddenly changes to 6 units hence 13 Is Not A functionFor 12, it is a function because it follows a consistent rate of change which is x or one unit of change.Answer:
12) The function is linear.

Distributive Property
3x+6=2x+14
Isolate the variable
3x+6-6=2x+14-6 which is 3x=2x+8

A family prepares an emergency kit for their home. The kit contains 63 gallons of drinking water. The family's daily drinking water needs are 3 1/2 gallons for the adults and 1 3/4 gallons for the children. For how many days would this emergency water supply last the family

Step-by-step explanation:
Total gallons of the family's drinking water needs = gallons consumed by children + gallons consumed by adults
3[tex]\frac{1}{2}[/tex] + 1[tex]\frac{3}{4}[/tex] =
Converting to decimals
3.5 + 1.75 = 5.25 = 5[tex]\frac{1}{4}[/tex]
If there are 63 gallons, the water supply would last for :
63 / 5.25 =12 days

The perimeter of the base of a square pyramid is 40 feet. The slant height of the pyramid is 12 feet. Find the surface area of the pyramid.
SHOW WORK
Answers
9514 1404 393
Answer:
340 ft^2
Step-by-step explanation:
The length of one side is 1/4 of the perimeter, so is 10 ft.
The area of the base is the square of the length of the side:
base area = (10 ft)^2 = 100 ft^2
__
The lateral area is the area of four triangles, each with a base of 10 ft and a height of 12 ft.
lateral area = 4(1/2)(10 ft)(12 ft) = 240 ft^2
__
The total surface area is the sum of the base area and the lateral area:
surface area = base area + lateral area
surface area = (100 ft^2) +(240 ft^2) = 340 ft^2
