The length of a rectangle is two times
its width. If the perimeter of the
rectangle is 150 in, what is the length of
the rectangle?
Answer:
length=50
width=25
step-by-step explanation:
=length=2x
=width=x
=perimeter 2(l+b)
=2(2x+x)×150
=2x+x=150÷2
=2x+x=75
=3x=75
=x=75÷3
=25
=length=25×2=50
=width=25

Answer:
Prism A: 264; Prism B: 265.125
Step-by-step explanation:
✔️Surface area of the triangular prism = base area + Perimeter*Height of prism
Base area = ½*bh
b = 6 cm
h = 8 cm
Base area = ½*6*8 = 24 cm²
Perimeter of base = 6 + 8 + 10 = 24 cm
Height of prism = 10 cm
Surface area of the triangular prism = 24 + 24*10 = 264 cm²
✔️Surface area of rectangular prism = 2(LW + LH + HW)
L = 5.25 cm
W = 5.25 cm
H = 10 cm
Surface area of rectangular prism = 2(5.25*5.25 + 5.25*10 + 10*5.25)
= 265.125

After school Rayah skateboards at a constant rate from her house to her friend's house 1.8 miles away. It takes her 12 minutes to get there. Which 2 variable equation represents this situation?
Answer:
Step-by-step explanation:
Given that:
Distance to friends's house = 1.8 miles
Time taken = 12 minutes
Since the rate is constant :
The rate Is related to distance and time :
The two variable equation which represents the equation is :
Speed = Distance / time
The water of a tank is initially 24 feet, and it is being
drained at a rate of 3 feet per day. The equation below
expresses the water level, y, in feet, in terms of the number
of days, x, since the tank began draining.
y = 24 - 3x

equation because it represents the moment when the tank
will be empty. Which of the following is the x-intercept of
the equation above?
Answer:

15x-8-3x=16 pls help
Answer:
x=2
Step-by-step explanation:
Combine like terms, add 8 to both sides of the equation, simplify, divide both sides by the same term, simplify
Answer:
x = 2
Step-by-step explanation:
1. Combine like terms
15x - 8 - 3x = 16
1 2 − 8 = 1 6
2. Add 8 to both sides of the equation
1 2 − 8 = 1 6
+8 +8
3. Simplify
12x = 24
12x/12 = 24/12
x = 2

Answer:
x = -8
Step-by-step explanation:
9/4 = (x-10)/x
Cross multiplying,
9x = 4(x - 10)
9x = 4x - 40
9x - 4x = -40
5x = -40
x = -40/5
x = -8

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2
Answer:
-11/10 (fraction) or -1.1 (decimal)
Step-by-step explanation:
The slope formula is m=(y2-y1)/(x2-x1)
x1 = 7
x2 = -3
y1 = -7
y2 = 4
So, it’s: (4 - (-7))/(-3-7)
= (4+7)/(-3-7)
= (11)/(-10)
= -11/10 or -1.1

Answer:
3. P = 48 units A = 116 units²
Step-by-step explanation:
A = 12 x 12
= 144
Now we can subtract the missing areas. 4 x 4 = 16 and 6 x 2 = 12.
144 - 16 - 12
= 116 units²
P = 12 + 12 + 12 + 12
= 48 units
The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost
Answer:
100 bicycle
Step-by-step explanation:
Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.
x is the number of bikes
To minimize the cost, dC/dx = 0
dC/dx = 10x - 1000
Since dC/dx = 0
0 = 10x - 1000
-10x = -1000
x = 1000/10
x = 100
Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

A water tank already contains 56 gallons of water in Baxter begins to fill it. water flows into the tank at a rate of 8 gallons per minute. write a linear equation to model this situation. Find the volume of the water in the sink 5 minutes after Baxter begins filling the tank.
Answer:
Equation: y = 8x + 56
After 5 minutes, the volume of the water was 96 gallons
Step-by-step explanation:
Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.
Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.
There are already 56 gallons of water in the tank, so b will be 56.
Plug in these values into the equation:
y = 8x + 56
So, the linear equation is y = 8x + 56
Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:
y = 8x + 56
y = 8(5) + 56
y = 40 + 56
y = 96
So, after 5 minutes, the volume of the water was 96 gallons
