P=2(L+W)
100≥P

L is 4 times W
L=4W
sub 4W for L

100≥2(4W+W)
100≥2(5W)
100≥10W
divide both sides by 10
10≥W

the greatest possible width is 10cm

You are riding the swings at a fair. What are the coordinates of your location after a rotation of 180°?

nekit [7.7K]

Answer:

(6, -3)

Step-by-step explanation:

The actual coordinates are x = -6 and y = 3

If we rotate 180 degrees and the center of rotation is at (0,0), all we need to do is invert the signal of each axis, that is, we invert the sign of the original x-coordinate and invert the signal of the original y-coordinate.

So the final x-coordinate is - (-6) = 6

And the final y-coordinate is - (3) = -3

So the coordinates will be (6, -3).

Solise is planting 24 bushes and 16 trees in equal rows. She wants all the rows to be exactly the same with no plants left over.

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━

Since Solise want to plant both trees and bushes in the same number of rows, you need to find the common factor.

Since the question is asking what the greatest number of rows she can plant, you have to find the greatest common factor.

The greatest common factor of 24 and 16 is 8.

You can plant 24 bushes in 8 rows (meaning you can divide it by 8), and 16 trees in 8 rows (meaning you can divide it by 8). Since the greatest number you can divide them both by is 8, the GCF of 24 and 16 is 8.

So the greatest number of rows Solise can plant is 8 rows.

Marcus ate half of a pizza on Monday night. He then ate one third of the remaining pizza on Tuesday. Which of the following expr

Strike441 [17]

<em><u>Option E</u></em>

<em><u>The expression show how much pizza Marcus ate in total is:</u></em>

$Total = \frac{1}{2} + \frac{1}{3} \times \frac{1}{2}$

<em><u>Solution:</u></em>

Given that,

Marcus ate half of a pizza on Monday night

He then ate one third of the remaining pizza on Tuesday

Therefore,

$Monday\ night = \frac{1}{2}\\$

Remaining is given as:

$Remaining = 1 - \frac{1}{2} = \frac{1}{2}$

He then ate one third of the remaining pizza on Tuesday

Therefore,

$Tuesday = \frac{1}{3} \times \frac{1}{2}$

<em><u>Thus expressions show how much pizza Marcus ate in total is:</u></em>

Total = monday night + tuesday

$Total = \frac{1}{2} + \frac{1}{3} \times \frac{1}{2}$

Thus Option E is correct
