Answer:
The length of the rectangle is 30 feet.
Step-by-step explanation:
Because the equation for area is length times width, you would have to set the two equations to seventy and multiply them.
<em> (x+5) (x+2) = 70</em>
<em> </em><em>2x + 10 = 70</em>
Then, you would have to subtract ten from both sides, cancelling it from the left side.
<em> 2x = 60</em>
<em />
Then do the opposite and divide sixty by two, therefore getting a length of thirty feet.
Interest = 500 x .03 x 4
I = 60
Closing Balance = 500 (p) + 60 (1)
Closing Balance = 560
Answer:
The area of the tablecloth showing is approximately 45.55 square feet
Step-by-step explanation:
The diameter of the dinner table, D = 8 feet
The diameter of each plate, d = 1 feet
The number of people at the dinner table = 6 people
The number of plates = 6 plates
The area of the table cloth, A₁ = π·D²/4
∴ A₁ = π × 8²/4
The area covered by the 6 plates, A₂ = 6·π·d²/4
A₂ = 6 × π × 1²/4
Let 'A' represent the area of the tablecloth showing when the table is set for six people, we have;
A = A₁ - A₂
∴ A = π × 8²/4 - 6 × π × 1²/4 ≈ 45.55 ft.²
The area of the tablecloth showing when the table is set for six people, A ≈ 45.55 ft.²
<h3>Question:</h3>
2x-5y=-28 find the value of y when x equals -19
<h3>Answer:</h3>
Y = - 2
<h3>Step-by-step explanation:</h3>
First you plug in -19 where x is 2(-19)-5y = -28
Remove parentheses -2 · 19-5y= -28
Multiply -2 by 19 -38-5y= -28
Add 38 to both sides -5y = 10
Divide both sides by -5 [tex]\frac{-5y}{-5} =\frac{10}{-5}[/tex
you will get -2 which is the answer.
