it takes 63 minutes for four people to paint nine walls how many minutes does it take seven people to paint four walls?

joja [24]

Answer:

16 minutes

Step-by-step explanation:

If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes

Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person

When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall

4 min per wall for 4 walls then total time will be 4*4=16 minutes

Ms. Perry bought a plant and is tracking the height of the plant each week. If y represents the height of the plant, in inches,

VMariaS [17]

Answer:

When Ms. Perry bought the plant, its height was 5 inches. The plant grew at the rate of 2.5 inches per week.

Step-by-step explanation:

The rate of change, or slope, represents the rate at which the height of the plant increased per week.

Use the points (2 , 10) and (4 , 15) from the table to calculate the rate of change, also known as the slope.

y2 - y1 = 15 inches-10 inches

x2 - x1 4 weeks-2 weeks

2.5 inches/1 week or 2.5 inches per week

So, the rate of change is 2.5 inches per week.

Now, find the y-intercept, b, by using the equation y = mx + b, where m is the slope of the line represented by the given table of values and (x , y) is any point on the line.

Substitute m = 2.5 and (x , y) = (2 , 10) in the above equation to find out the initial height of the plant.

y=mx+b

10=2.5 (2) + b

5=b or b=5

So, the initial height of the plant was 5 inches.

Therefore, the situation represented by the table is when Ms. Perry bought the plant, its height was 5 inches. The plant grew at the rate of 2.5 inches per week.

This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find th

NISA [10]

Answer:

The volume of the triangular prism: 59.2 $ft^{3}$

The value of the concrete used is: 16*4 = $64

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo

My answer:

As we know that, the formula to find out the volume of the triangular prism is:

V = $\frac{1}{2} a*b*h$ when h is the height and a&b are the length of the two square edges. So we have:
