help please! I just want to actually get my homework done
Answer:
72/b = h
Step-by-step explanation:
plug in known values
A = 1/2 (bh)
36 = 1/2 (bh)
goal is to isolate the variable h (height)
multiply both sides by 2 to cancel out 1/2
36 × 2 = 1/2 × 2 (bh)
72 = bh
divide both sides by b (base)
72/b = bh ÷ b
72/b = h
i dont see the value for base given so this would be the final answer as far as i know

Answer:
B = 1/243
Step-by-step explanation:
Suppose you want to know how fast you traveled from the park to the library. As you moved, your speed varied from second to second. Therefore, in order to describe your speed, you must describe the average speed of the entire trip. Average speed is one reason. It is the distance an object moves divided by the time it takes to travel that distance. If you covered the 1 km distance to the library in 15 min, or 0.25 h, your average speed was 1 km / 0.25 h or 4 km / h.
Step-by-step explanation:
In order to describe speed of an object, we must describe the average speed of the entire trip. It is equal to the distance moved divided by time taken.
If a person covers a distance of 1 km to the library in 15 minutes, we can find its average speed.
Firstly, we convert 15 minutes to hour, 15 min = 0.25 hours
Now, using formula of speed = distance/time
[tex]v=\dfrac{1\ km}{0.25\ h}\\\\v=4\ km/h[/tex]
It means that the average speed of the person is 4 km/h. Hence, the given statement is true.
To determine the _____________, measure the distance around the outside of a closed shape such as a square.

Completely factor the following polynomial: 8x^3−125
Answer:
(2x-5)(4x^2+10x+25)
Explanation:
Factoring difference of cubes (a3−b3): (a−b)(a2+ab+b2)
Here, a is 2x because the cube root of 8 is 2 and the cube root of x3 is x, b is 5 because the cube root of 125 is 5.
Plug the numbers in:
(2x−5)((2x)2+2x⋅5+52)
(2x−5)(22x2+10x+25)
(2x−5)(4x2+10x+25)
Answer:
8x^3 can also be written as [tex](2x)^{3}[/tex].
-125 can also be written as [tex]-5^{3}[/tex].
Factoring the polynomial:
[tex](2x)^3+(-5)^3[/tex]

what is the missing x for 2x + 65 = 180
Answer:
x=115/2
Step-by-step explanation:
Answer:
x = 57.5
Step-by-step explanation:
Step 1: Write equation
2x + 65 = 180
Step 2: Solve for x
Subtract 65 on both sides: 2x = 115Divide both sides by 2: x = 115/2Divide: x = 57.5Step 3: Check
Plug in x to verify it's a solution.
2(115/2) + 65 = 180
115 + 65 = 180
180 = 180
Need help urgently with this geometry question
=======================================================
Explanation:
The angles (2x+24) and x are same side interior angles. Same side interior angles are supplementary when we have parallel lines.
(2x+24) + (x) = 180
2x+24+x = 180
3x+24 = 180
3x = 180-24
3x = 156
x = 156/3
x = 52
Lilly starts hiking along a trail at 3 miles per hour. Dave starts hiking the same trail from the same starting point at 3.5 miles per hour. If lilly walked 2 miles before Dave started hiking , will he catch up to her ? write a equation
Given:
Lilly starts hiking along a trail at 3 miles per hour.
Dave starts hiking the same trail from the same starting point at 3.5 miles per hour.
lilly walked 2 miles before Dave started hiking.
To find:
Whether he will catch up to her and write an equation.
Step-by-step explanation:
Let the number of hours when both are hiking be h.
lilly walked 2 miles before Dave started hiking at 3 miles per hour.
Lilly hiking = 2+3h
Dave starts hiking the same trail from the same starting point at 3.5 miles per hour.
Dave hiking = 3.5 h
He will catch her if hiking distance of both are equal.
[tex]2+3h=3.5h[/tex]
Subtract 3h from both sides.
[tex]2=3.5h-3h[/tex]
[tex]2=0.5h[/tex]
Divide both sides by 0.5.
[tex]\dfrac{2}{0.5}=h[/tex]
[tex]4=h[/tex]
Therefore, Dave will catch her after 4 hours.
Dave will catch up Lilly after 4 hours.
Since Lilly starts hiking along a trail at 3 miles per hour, and Dave starts hiking the same trail from the same starting point at 3.5 miles per hour, if Lilly walked 2 miles before Dave started hiking, to determine when he will have catch up to her the following calculation must be performed:
The initial distance between the two must be divided by the difference between their speeds. 2 / (3.5 - 3) = X 2 / 0.5 = X 4 = X
Therefore, Dave will catch up Lilly after 4 hours.

Point N is on line segment MO. Given NO = 2x– 3, MO = 3x + 5, and
MN = 2x + 3, determine the numerical length of MO.
Answer:
The numerical length of MO is 20 units
Step-by-step explanation:
Let us solve the question
∵ Point N is on line segment MO
→ That means point N divides segment MO into two parts MN and NO
∴ MO = MN + NO
∵ MO = 2x + 5
∵ MN = 2x + 3
∵ NO = 2x - 3
→ Substitute them in the equation above
∴ 3x + 5 = (2x + 3) + (2x - 3)
→ Add the like terms in the right side
∵ 3x + 5 = (2x + 2x) + (3 - 3)
∴ 3x + 5 = 4x + 0
∴ 3x + 5 = 4x
→ Subtract 3x from both sides
∵ 3x - 3x + 5 = 4x - 3x
∴ 5 = x
∴ The value of x is 5
→ To find MO substitute x by 5 in its expression
∵ MO = 3x + 5
∴ MO = 3(5) + 5
∴ MO = 15 + 5
∴ MO = 20 units
The numerical length of MO is 20 units

C =
Answer:
c = 208.8
Step-by-step explanation:
a. [tex]\frac{c}{7.2} =29[/tex] To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.
b. [tex]\frac{c}{7.2} =29[/tex] You need to move the 7.2 to the other side. So, multiply both sides by 7.2, because it's being divided, so multiplying will cancel it out.
c: [tex]c = 29 * 7.2[/tex] Then, multiply 7.2 by 29. (The * symbol means multiply)
d. c. = 208.8 The answer is 208.8, which is rounded to the tenths place.

If A=1/2 h (b1 +b2) is the formula for the area of a trapezoid, find the height of the trapezoid that has an area of 78 in ^2 and base lengths 5 in and 8 in.
Answer:
A. 12in
Step-by-step explanation:
Given parameters:
Area of trapezoid = 78in²
Base lengths = 5in and 8in
Unknown:
Height of the trapezoid = ?
Solution:
A = [tex]\frac{1}{2}[/tex] (b₁ + b₂)h
b₁ and b₂ are 5in and 8in respectively.
Input the parameters and solve for h;
78 = [tex]\frac{1}{2}[/tex] (5 + 8)h
Multiply both sides by 2;
156 = 13h
h = 12in
The height of the trapezoid is 12in
