Answer 1

Answer:

1. 540 cm^3

2. 448 cm^3

Step-by-step explanation:

1. Volume of rectangular prism is height times width times length, hwl, or

18*7.5*4 = 540, 540 cm^3

2. Volume of triangular prism is surface area of base times length

the length is 14 cm, and the base is the triangle, The area of a triangle is half of the base times the height, 1/2b * h. The base of this triangle is 8 cm, and the height is also 8 cm, 1/2(8) * 8 = 4*8 = 32, 32 times the length of the triangle is 32*14 = 448 cm^3

yards. What is the area of the city park around the playground?

Answers

Answer:

wouldn't the answer be 10800 yards

Step-by-step explanation:

because the formula of the area of a rectangle is l x w. so 90 x 120 is 10800

I think it’s 10800 yards because 90 x 120 is 10800 but I’m not sure tho

Below is the graph of equation y=-lx-2l+2. Use this graph to find all values of x such that

a. y>0
b.y<0
c. y=0

THIS IS AN RSM promblem Please Help

Answers

The graph is a linear function defined by several pairs of coordinates, and the computation for x and y values is as follows.

Graph equation

y=−|x−2|+2

When x=0

then

y=−|0−2|+2

y=−|−2|+2

y=−2+2

y=0

When x=1

then

y=−|1−2|+2

y=−|−1|+2

y=−1+2

y=1

When x=2

then

y=−|2−2|+2

y=−|0|+2

y=−0+2

y=2

When x=3

then

y=−|3−2|+2

y=−|1|+2

y=−1+2

y=1

When x=4

then

y=−|4−2|+2

y=−|2|+2

y=−2+2

y=0

When x=5

then

y=−|5−2|+2

y=−|3|+2

y=−3+2

y=-1

Hence, the value of (x, y) are as follows

y=0 x=0

y=1 x=1

y=2 x=2

y=1 x=3

y=0 x=4

y=-1 x=5

What is the area of a parallelogram?

The area of a parallelogram = base × height = b h.

We can easily divide this irregular figure into a right-angle triangle and a parallelogram.

Hence, A = one-half b × h and A=b + h; two formulas will be required to find the area of this irregular figure.

Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?

Answers

Answer:

The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed

Step-by-step explanation:

Answer:

The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.
