Michelle can run 5.44 miles in 68 minutes. What is Michelle's average speed, in miles per minute ?
Phoenix [80]
5.44 miles ... 68 minutes
x miles = ? ... 1 minute

If you would like to know how many miles can Michelle run in 1 minute, you can calculate this using the following steps:

5.44 * 1 = 68 * x
5.44 = 68 * x      /68
x = 5.44 / 68
x = 2 / 25 = 0.08 mile

Result: Michelle can run 0.08 mile in 1 minute.

nikklg [1K]

Answer:

  • \frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}

Step-by-step explanation:

<u>Given</u>

  • \frac{5}{3}xz^a*bx^cy^dz^2 = 15x^7z^{10}

<u>Simplify</u>

  • \frac{5}{3}b*x^{1+c}z^{a+2}y^d = 15x^7z^{10}y^0

Compare left and right sides and

<u>Find b:</u>

  • <u />\frac{5}{3} b = 15 ⇒ b = 15*3/5 = 9

<u>Find c:</u>

  • 1 + c = 7 ⇒ c = 7 - 1 = 6

<u>Find a:</u>

  • a + 2 = 10 ⇒ a = 10 - 2 = 8

<u>Find d:</u>

  • d = 0

<u>Solution is:</u>

  • \frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}

Find the area of the polygon.
Salsk061 [2.6K]

Answer:

174 ft²

Step-by-step explanation:

The polygon cam be decomposed into two rectangles.

The area of the polygon = rectangle A + rectangle B

Area of rectangle A = L* W

L = 18 ft

W = 9 ft

Area of rectangle A = 18*9 = 162 ft²

Area of rectangle B = L* W

L = 20 - 18 = 2 ft

W = 6 ft

Area of rectangle A = 2*6 = 12 ft²

✔️Area of the polygon = 162 + 12 = 174 ft²

You have 3 apples, 4 pears, 7 oranges, and 14 bananas. Your friend gives you 5 times that amount. Your other friend gives you 75
yuradex [85]

Answer:

6384

Step-by-step explanation:

Since the question is only talking about fruit, I'm going to ignore which type and add the fruits together.

3+4+7+14=7+7+14=14*2=28

I have 28 fruits, and my friend give me 5 times that, so my friend gives me 5*28, or 140 fruits. So in all, I have 140 plus my original 28, or 168 all together

Then, my other friend gives me 75 times more. Wow. I don't think I've seen this many fruits all in one place, but this is the world of math, so who cares?

75*168=(70*168)+(5*168)=7000+4200+560+500+300+40=11760+840=

12600 fruits that your friend gives you. In addition to the 168 that you had before. Pardon my french, but why the ...

12600+168=12768 fruits at the height of your fruity domination.

Then, your friend takes half

12768/2=6384 fruits.
