Answer:
The volume of the triangular prism is <em>51</em><em>.</em><em>84</em><em> </em><em>cm</em><em>^</em><em>3</em>.
Step-by-step explanation:
The formula of the volume of a prism is:
V = Ah
where:
V = Volume of prism
A = Area of uniform cross-section or base of prism
h = Height of prism = 6 cm
We can substitute the information given in the problem into this formula.
To find A, we need to find the area of the triangular base.
A = bh / 2
where:
b = Base of triangle = 5.4 cm
h = Perpendicular height of triangle = 3.2 cm
We can substitute the information given in the problem into this formula.
A = ( 5.4 × 3.2 ) / 2
A = 17.28 / 2
A = 8.64 cm^2
Substitute the value of A into the original volume of a prism formula with the other information given in the problem.
V = Ah
V = ( 8.64 ) ( 6 )
V = 51.84 cm^3
Answer:
markup price = $25.31
retail price = $59.06
Step-by-step explanation:
Markup price is 75% OF 33.75
Retail price is original price (33.75) PLUS the markup price (to be found)
Firstly, converting a percentage to a decimal is simple. We simply divide by 100. So:
75% = 75/100 = 0.75
Now, to find markup, we multiply:
33.75 * 0.75 = $25.31
Now, the retail price is SUM of original and markup, that would be:
retail price = 33.75 + 25.31 = $59.06
Thus,
markup price = $25.31
retail price = $59.06
Answer: 15 ft
Step-by-step explanation: shadow / height
8.4/6=1.4
21/1.4=15
Answer:
275 is the amount SPENT per month for rent. Since you are decreasing that amount from your savings, it is represented with a negative sign.
The formula is: y = mx + b where
- m is the rate --> -275 per month
- b is the fixed rate --> 3500 savings
If you think about it logically - You have 3500 and spend $275 per month
1st month: 3500 - 275 = 3225
2nd month: 3225 - 275 = 2950
3rd month: 2950 - 275 = 2675
4th month: 2675 - 275 = 2400
5th month: 2400 - 275 = 2125
6th month: 2125 - 275 = 1850
It is easier to write it as an equation where x is the number of months and y is the balance for that month.
y = -275x + 3500
To check if the point (6, 1850) is on the line, input x = 6 and y = 1850
y = -275x + 3500
1850 = -275(6) + 3500
1850 = -1650 + 3500
1850 = 1850
Since it makes a true statement, (6, 1850) is a point on the line.
The angles would be 38.85, 51.19, and 90. I attached a picture showing the steps.
