Answer:
P = 2( l + b )
=>130 = 2 (l + 30)
=>130 = 2l + 2*60
=> 130 = 2l + 60
=> 130 - 60 = 2l
=> 70 = 2l
=> 70/2 = l
=> 35 = l
Length = 35cm
Area = l * b
=> A = 35 * 30
=> A = 1050
Therefore area = 1050[tex]cm^{2}[/tex]

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

At what rate is Riya applying mulch in m 3 m 2 m 2 m 3 start fraction, start text, m, end text, cubed, divided by, start text, m, end text, squared, end fraction?
Answer:
0.25m³
Step-by-step explanation:
If Riya is applying mulch to her garden. She applies it at a rate of 250,000 cm³ for every m², to know how much she is applying in m³ for every m², we will make use of the conversion formula:
100cm = 1m
1cm = 1/100m
1cm = 0.01m
250,000cm³ = 250,000 × 1cm×1cm×1cm
250,000cm³ = 250,000×0.01×0.01×0.01
= 250,000×0.000001
= 0.25m³
Hence Riya is applying at 0.25m³ per m²
Answer:
0.25m³ / m²
Step-by-step explanation:
Given that:
Rate of application = 250,000 cm³ of mulch per m²
The rate of application in m³ per m² can be calculated thus :
Converting 250,000 cm³ to m³
1cm = 1/100 = 0.01m = 1 * 10^-2 m
Hence
1cm³ = (1 * 10^-2 m)³ = 1 × 10^-6 m³
Hence,
250,000cm³ = (250,000 * 10^-6)m³ = 0.25m³
Hence, rate of application in m³ / m² equals
0.25m³ / m²
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.

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.

At this rate,how much would Gianna earn for 8 hours of work? Show work to justify your answer.
At this rate, how long would Gianna have to work to earn $60? Show work to justify your answer.
150 ÷ 20 = 7.5 minutes per 1 mile

Answer: x=15/19 =0.789
Step-by-step explanation: -12*x+1-(7*x-14)=0

Subtract 15 from both sides of the equation :
-19x = -15
Multiply both sides of the equation by (-1) : 19x = 15

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.

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
