Answer:
Option A (2197 cm³)
Step-by-step explanation:
For a cube with length of each side "a" , it's
Total Surface Area = 6a² Volume = a³_____________________________________________
According to the question ,
Total Surface Area = 1014 cm²
Let the length of each side of cube be 'a'.
Using the formula ,
[tex]6a^{2} =1014[/tex]
[tex]=> a^{2} =\frac{1014}{6} = 169[/tex]
[tex]=> a = \sqrt{169} = +13 \: or -13[/tex]
But length can't be negative . So , length of each side = 13 cm
∴ Volume of cube = 13³ = 2197 cm³
What is the value of y in the solution to the following system of equations?
5x - 3y = -11
2x - 5y = -14 (1 point)
O-1
OO
1
2
Answer:
Option D is the correct answer.
Step-by-step explanation:
The equations are:
5x - 3y = -11 Eqn 1
2x - 6y = -14 Eqn 2
We have to find the value of y so we will eliminate x.
Multiplying Eqn 1 by 2
2(5x-3y=-11)
10x-6y=-22 Eqn 3
Multiplying Eqn 2 by 5
5(2x-6y=-14)
10x-30y=-70 Eqn 4
Subtracting Eqn 4 from Eqn 3
(10x-6y)-(10x-30y)= -22-(-70)
10x-6y-10x+30y = -22 + 70
24y = 48
[tex]\frac{24y}{24}=\frac{48}{24}\\y=2[/tex]
Therefore,
Option D is the correct answer.

The restaurant sold coffee and tea during the breakfast shift. The number of cups of tea they sold was 6 more than 1/3 of the number of cups of coffee sold. If the total cups of coffee and tea sold was 70, how many cups of each were sold?
Answer:
cups of tea = 22
cups of coffee = 48
Step-by-step explanation:
c = coffee
t (tea) = 6 + 1/3c
t + c = 70
c + 6 + 1/3c = 70
4/3c + 6 = 70
4/3c = 64
4c = 192
c = 48
t = 70 - 48 = 22
The width of a rectangle is 4y - 8.5 feet and the length is 8.5y + 10 feet. Find the perimeter of the rectangle.
Answer:
P = 25y + 3
Step-by-step explanation:
Draw out the figure. You should know that 2(width+length) = Perimeter.
Therefore, when you plug everything in, your expression should look like this:
2(12.5y+1.5) = P
In the end, since you don’t have any other information about y, your final answer would be 25y + 3 = P.

Patty wants a triangle garden in her backyard for all of her vegetables. She
is going to use three pieces of fencing that measure 7 feet, 10 feet, and 8
feet. Will her garden be in the shape of a right triangle? Why or why not?
Answer:
Step-by-step explanation:
the hypothenuse is the largest side in the right triangle
we have 2 side, 7,8
in a right triangle, c^2= a^2+b^2
where c is the hypothenuse
c^2=49+64=113
c=sqrt113=aprox 10.6
so, the answer is no if it has to be exactly 10 ft the hypotenuse

The area of a rectangular dining room is 16 square meters. The perimeter is 16 meters. What are the dimensions of the dining room?
Answer:
4
Step-by-step explanation:
The area is 16, and you know that it's 2 sides u need to multiply
The perimeter is 16, and you know that you need to add up all the sides
So....
A = b * h
A = 4 * 4
A = 16 CORRECT
And....
P = S + S + S + S ( s = sides)
P = 4 + 4 + 4 + 4
P = 16 CORRECT
