Answer:
Lengths of the sides (there are 3 sides in an equilateral triangle) of the base of prism is5.72cm each.
Step-by-step explanation:
As the base of triangular prism is equilateral:
∴ Area of base = (√ 3 / 4)× (side)²
According to question:
height of prism = height (side) of base
Volume of prism = 81 cm³,
∴ Volume of prism = Area of base x height
⇒ 81 cm³ = (√ 3 / 4)× (side)² × height ∵ side = height
⇒ 81 cm³ = (√ 3 / 4)× (side)³
⇒ 81 × (4/√3) cm³ = side³
⇒ ∛(81 × (4/√3) cm = side
⇒ side = 5.72cm
Hello from MrBillDoesMath!
Answer:
21
Discussion:
f(x) = 3x2 - 2x + 5
Substitute x = -2 in f(x) above to get
f(-2) =
3 (-2)^2 - 2(-2) + 5 = => (-2)^2 = (-2) * (-2) = +4, -2(-2) + + 4
3*4 + 4 + 5 =
12 + 4 + 5 =
21
Thank you,
MrB
y=-2x+8
y=1/2x
y=-3/4x-1
y=x+5
please show work step by step for each.
1. The equations in this example are already set equal to "y". Identify the slope and y-intercept in each equation. Remember: y = mx + b, where m = slope and b = y-intercept.
y = 2x + 1
slope = 2
y-intercept = 1
y = -x + 7
slope = -1
y-intercept = 7
2. Graph the lines.
This example used the slope-intercept method of graphing straight lines.
The b-value tells you where the line crosses the y-axis.
The slope, m, tells you the rise over the run.
If you need help graphing lines, see Graphing Linear Equations.
Find the intersection point (where the lines cross).
These lines cross at the point (2,5).
This means the solution to this system is:
Solution: x = 2 and y = 5.

3. CHECK: Substitute x = 2 and y = 5 into BOTH of the original equations. If your solutions are correct, both equations will be true!
y = 2x + 1
5 = 2(2) + 1
5 = 5 (check)
y = -x + 7
5 = -(2) + 7
5 = 5 (check)
So, we need to do the distance she travelled (21 miles) divided by the rate at which she travelled (4 hours). Therefore, because 21 divided by 4 is 5.25, she biked at a speed of 5.25 mph (Miles per hour). So, if she bikes 5.25 miles every hour we can divide 42 by 5.25 to get the time it would take her to travel 42 miles. Now, 42 divided by 5.25 equals 8, so that means for Shelly to bike 42 miles at her average speed of 5.25 mph, it would take her 8 hours.
Answer:
5.25 mph , for 42 mile she would ride around 8 hours
Step-by-step explanation:
you need to divide the 21 miles by the 4 hours to find how many miles Shelly rode for one hour and that will be your answer ( 5.25 mph)
Answer:
Step-by-step explanation:
Dividing by 0.2 is the same as multiplying by 5. Check your calculator if you don't believe me.
