This is true

Step-by-step explanation:

10x1 is 10. 10x10 is 100. but if u did 100x10 you would add the amount of zeros total. which would be 1000. so 400x10 is 4000

Find a set of parametric equations for the line of intersection of the planes x-3y+6z=4 5x+y-z=4
Inessa05 [86]

Answer:

Step-by-step explanation:

Two equations of planes are given.

We have to find the equation of the line which is formed by intersection of these two planes in parametric form

x-3y+6z=4 \\5x+y-z=4

Let us eliminate one variable

Multiply I equation by 5 and subtract II from 5 * I

5x-15y+30z=20 \\5x+y-z=4

-16y+31z=16 \\

16y+16 = 31z

Or y+1 =\frac{31z}{16}

Consider II equation

5x+y-z=4

5x+\frac{31z}{16}-1 -z=4\\5x+\frac{15z}{16}=5\\x=\frac{3z-16}{16}

Let z=z

x = \frac{3z-16}{16} and y = \frac{31z}{16}-1

Can any one pleasssssseeee help me with algebra home work? I need help on A, B, and C

By looking at this scatter plot you can see that 2 people bowled above their average, 1 person bowled the same number for their average and their highest score (this person bowled 200 as their highest score as well as their average), and the biggest difference between someones high score and their average is one person has 200 for their bowling average, but only 175 for their high score. Everyone else's high scores and averages are about the same.

Mjhs is refinishing a basketball court and decided to paint everything shown below blue. How many square feet will be painted bl
SashulF [63]

Answer:

<h2>Mjhs needs 189.25 square feet of blue paint, approximately.</h2>

Step-by-step explanation:

As you can observe in the image attached, the basketball court is a composite figure formed by a rectangle and half of a circle.

The rectangle has dimensions of 10 feet by 15 feet. The circle has a diameter of 10 feet.

The expression of this composite area would be

A= w \times l + \frac{\pi (\frac{l}{2} )^{2} }{2}

Where w = 15 \ ft and l = 10 \ ft. Replacing these values, we have

A= 15 \times 10 + \frac{3.14 (\frac{10}{2} )^{2} }{2}\\ A=150 + \frac{3.14 \times 25}{2}=150+39.25 \\ A \approx 189.25 \ ft^{2}

Therefore, Mjhs needs 189.25 square feet of blue paint, approximately.
