Answer:

base is 5

Step-by-step explanation:

the reason is 5 is because the formula of the parallelogram is base times height

since they gave us the area which is 20 and we have the height we have to do the opposite of multiplying which is divide so we divide 20 with 4 which gave is 5 as our base and to check 4 times 5 is 20 so its correct

Three numbers are in the ratio 1:2:3 and the sum of their cubes is 4500. Find the numbers​
kolbaska11 [484]
Let the numbers be 1k, 2k , and 3k respectively
Since the sum of their cubes is 4500,
(1k)³+(2k)³+(3k)³=4500
--> k³(36)= 4500
--> k = 5


Hence, the numbers are: 5,10 and 15 respectively

What is the rate of return when 35 shares of Stock A, purchased for $20/share, are sold for $815? The commission on the sale is
wariber [46]

Cost price:-

\\ \sf\longmapsto 35\times 20

\\ \sf\longmapsto 700

  • Commision=$6
  • Total sold price=815+6=823$

Now

Return=823-700=123

Rate of return

\\ \sf\longmapsto \dfrac{123}{700}\times 100

\\ \sf\longmapsto \dfrac{123}{7}

\\ \sf\longmapsto 17.5\%

PLEASE SHOW YOUR WORK!!!<br><br><br><br><br><br> Solve for y: 3^3 + 14 y- (25y - 13) = y + 7y - 9y
Marina86 [1]
<h2 /><h2>⟹</h2>

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

3^3+14*y-(25*y-13)-(y+7*y-9*y)=0

Equation at the end of step 1

((3³ + 14y) - (25y - 13)) - -y = 0

Pull out like factors :

40 - 10y = -10 • (y - 4)

Equation at the end of step3:

-10 • (y - 4) = 0

STEP4:

Equations which are never true:

Solve : -10 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

Solve : y-4 = 0

Add 4 to both sides of the equation :

y = 4

<h2>y = 4</h2>
