Answer:
3a by 4a
Step-by-step explanation:
For dimensions L and W, the area and perimeter are ...
A = LW = 12a^2
P = 2(L+W) = 14a
Using the second equation, we can find L:
L +W = 7a . . . . . divide by 2
L = 7a -W
Substituting into the area formula gives the quadratic ...
(7a -W)(W) = 12a^2
W^2 -7aW +12a^2 = 0 . . . . arrange in standard form
(W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)
Then we have the two solutions ...
W = 3a, L = 4a
W = 4a, L = 3a
The rectangle dimensions are 3a by 4a.

Find the slope.
Find the y-intercept
Write the equation (y=mx+b)
At Philip’s Phones you can get a new cell phone plan for $45 a month plus $30 activation fee.
9514 1404 393
Answer:
slope: 45y-intercept: 30equation: y = 45x + 30Step-by-step explanation:
The slope is the cost per month. (A slope is often expressed as a ratio: dollars per month, in this case.) The slope is 45.
The y-intercept is the value that obtains when the number of months (in this case) is zero. It is the activation fee, 30. The y-intercept is 30.
__
The equation in slope-intercept form is ...
y = mx + b . . . . . where m is the slope and b is the y-intercept
Using the above numbers, the equation is ...
y = 45x + 30

The sides of the base of a right square pyramid and its slant height are tripled. What is the surface area of the larger pyramid divided by the surface area of the smaller pyramid? A. 3 B. 6 C. 9 D. 12
Answer:
Step-by-step explanation:
If the base length and slant height are multiplied by 3, the surface area is multiplied by 3² = 9
A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches. 2 triangular sides have a base of 10 inches and height of 5.6 inches. 2 triangular sides have a base of 5 inches and height of 7.1 inches.
Answer:
Answer:
a) The base of the rectangular pyramid shown has an area of
60 square inches
b) A triangular face with a base of 10 inches has an area of 28 square inches.
c) A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) The total surface area of the pyramid is 151.5 square inches.
Step-by-step explanation:
a) Solving for question a, we were given the following parameters
A rectangular pyramid. The rectangular base has a length of 10 inches and a width of 6 inches
The formula used to calculate the rectangular base of a rectangular pyramid =
Length × Width
Where :
Length = 10 inches
Width = 6 inches
Rectangular base = 10 inches × 6 inches
= 60 inches²
Hence, the base of the rectangular pyramid shown has an area of 60 square inches
b) Solving for question b, we have the following values given:
2 triangular sides have a base of 10 inches and height of 5.6 inches.
First step would be to solve for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (10 inches × 5.6 inches) ÷ 2
= 56inches² ÷ 2
= 28 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 28 inches².
A triangular face with a base of 10 inches has an area of 28 square inches.
c) Solving for question c, the following parameters are given:
2 triangular sides have a base of 5 inches and height of 7.1 inches.
We would be to solving for one triangular side first.
The area of the one triangular side = (Base × Height) ÷ 2
= (5 inches × 7.1 inches) ÷ 2
= 35.5 inches² ÷ 2
= 17.75 inches²
Therefore, for the 2 triangular sides, since they have the same base and height, the other side as well would be 17.75 inches².
A triangular face with a base of 5 inches has an area of 17.75 square inches.
d) Solving for d, it is important to note that, a rectangular pyramid has 5 faces and they are: The rectangular base and 4 triangular faces
The formula for the total surface area of the rectangular pyramid is given as
Total Surface Area of the rectangular pyramid = Rectangular Base + Area of Triangular Side A + Area of Triangular Side B + Area of Triangular Side C + Area of Triangular Side D + Area of Triangular Side E
Total Surface Area of the Rectangular Pyramid = 60 inches² + 28 inches² + 28 inches² + 17.75 inches² + 17.75 inches²
Total surface Area of the Rectangular pyramid = 151.5 inches²
The total surface area of the pyramid is 151.5 square inches.

1. The cross section of an A-frame cottage is an isosceles triangle. If the
slope of one of the sides is 1.8 and it is 19 feet high at the peak, what angle
does the side make with the horizontal? What is the width of the cottage?
Answer:
21.12
Step-by-step explanation:
To solve this, it's best to use Cartesian planes. So we draw it in the Cartesian planes. From the question, we have {0, 19} and also {1.8, 0}.
If x = -1.8 and x = +1.8, then
1.8 = (19 - 0) / (0 - x)
1.8 = 19 / -x
x = -19 / 1.8
x = -10.56
Since we're having it in 2 quadrants then, we have 10.56 + 10.56 = 21.12 to be our width of the cottage
Pizza by the Pan sold 4 dozen pizzas in the afternoon. That night, they sold 2.5 times as many pizzas as they did during the afternoon. How many pizzas did they sell in all that day?
Answer:
they sold 14 pizzas all day.
Step-by-step explanation:
4 x 2 = 8
0.5 means half of what they sold in the afternoon
4 ÷ 2 = 2
now add them both together to get the number of pizzas they sold at night.
8 + 2 = 10
now add the afternoon and night together
10 + 4 = 14
answer: 14 pizzas

A small plant manufactures riding lawn mowers. The plant has fixed costs of GHC48,000 per day and a variable cost of GHC1,400 per unit produced. The mowers are sold for GHC1,800 each. The cost and revenue functions are in that order and , where is the total number of mowers produced and sold each day. How many units must be manufactured and sold each day for the company to break even?
Answer:
120
Step-by-step explanation:
The break-even point is the point where revenue =cost
48,000+ 1400x = 1800x
48000=400x
X=48000/400
X=120
Equilibrium quantity is 120 mowers

Two soccer balls are simultaneously kicked on parallel paths, from 15 feet apart on level ground. After 0.1 second, the balls are again 15 feet apart. 15 ft Must the two soccer balls have traveled the same distance in the first 0.1 second after they were kicked? If so, which theorem or definition can you use to show this? HELP QUICK WORTH 100 POINTS
Answer:
They do not have to always be 15 feet apart
Step-by-step explanation:
Becuase if they were kicked by different
people, then they might have different forces behind them and one could travel farther.
