A ramp is 11 ft high as shown below. How long is the ramp to the nearest foot?
Answers
Answer:
Length of the ramp is 79 ft.
Step-by-step explanation:
From the picture attached,
Height of the ramp = 11 ft
Angle between the elevated ramp and the horizontal base = 8°
By applying sine rule in the given triangle,
sin(8°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{11}{x}[/tex]
x = [tex]\frac{11}{\text{sin}(8)}[/tex]
x = 79.03 ft
x ≈ 79 ft
Therefore, length of the ramp is 79 ft.

x= the slope so the slope would be 1/1 which means you go up one over one to the right and down one over the the left and the slope would continue going until there is no more space left of the graph.

−7x − 2y = −13
x − 2y = 11
use the substitution method to find x and y
Answers
Answer:
x=3
y=−4
Step-by-step explanation:
Add 2y to both sides of the equation.
x=11+2y
−7x−2y=−13
Replace all occurrences of x with 11+2y in each equation.
−77−16y=−13
x=11+2y
and then you just connect the dots

What is the expected average of rolling a single die
Answers
Answer:
Mathwords: Expected Value. A quantity equal to the average result of an experiment after a large number of trials. For example, if a fair 6-sided die is rolled, the expected value of the number rolled is 3.5. This is a correct interpretation even though it is impossible to roll a 3.5 on a 6-sided die.
Step-by-step explanation:
hope it helps
Answer:
When you roll a fair die you have an equal chance of getting each of the six numbers 1 to 6. The expected value of your die roll, however, is 3.5.

is it true that the sum of two repeating decimal is always repeating decimal
Answers
Answer:
no. it isn't necessary.
Step-by-step explanation:
there are some cases where adding two repeating decimals results in a sum which does not have a repeating decimal. For example,
1 over 3
+
2 over 3
=
3 over 3
=1
. Thus, the sum of two repeating decimals is not always a repeating decimal.

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.
Answers
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.

Answer:
y-intercept is (0, -2) and asymptote of y = -2.5
Step-by-step explanation:
If you substitute 0 in for x and simplify, then you will have the y-intercept
y = [tex]\frac{1}{2} (7)^{0} - 2.5 = \frac{1}{2} (1) - 2.5 = \frac{1}{2} - 2.5 = -2[/tex]
The y-intercept is (0, -2)
If the -2.5 were not there, then the graph would have an asymptote at y = 0 or the x-axis
The -2.5 moves the graph down 2.5 units so that y = -2.5 is the asymptote
Therefore, the first answer is correct
