The second solid is a parallelepiped.

The volume of a parallelepiped is the area of the base times the height (the perpendicular distance from the base to the top face).

Given that the second solid has the same base of the cube and the same height, then the volumes of two solids are the same.

Answer: 1000 cubic feet.

Answer:  1000 ft³.

Step-by-step explanation:

Since, The volume of a cube = ( side )³

⇒ 1000 = (side)³ ⇒ side = 10

Hence, the side of the given cube = 10 feet

Since, the base of a cube = square having side 10 feet.

When we tilted the cube by 2 units,

Then, the base of the new solid = Rhombus having height 10 meters and base 10 feet,

Since, the square and rhombus are lying in the same base ( Shown in diagram)

Area of rhombus (Base of new solid) = Area of square having side 10 feet = 100 ft²

Since, the height of new solid is also 10 feet. the volume of new solid = Area of its base × height

=  10 × 100

= 1000 ft

The graphs of two linear equations ax + by = c and bx - ay = c, where a, b, c are all not equal to zero.
marin [14]
Let us find the slopes of the two lines

ax+by=c, slope m1 = -a/b

bx-ay=c, slope m2 = b/a

m1*m2 = (-a/b)(b/a) = -1

Therefore the two lines are perpendicular so the answer is D

Each 7th grader brings $5 for charity, while each 8th grader brings in $8. The total collected is $1380. There are 10 more 8th g
Scilla [17]

Answer:

7th graders- 100 students

8th graders- 110 students

Step-by-step explanation:

Let the number of 8th graders be represented by x and 7th graders be represented by y

<u>Equation based on number</u>

There difference between 8th and 7th graders is 10 hence equation becomes

x-y=10

<u>Equation based on contribution</u>

While x contribute each $8 and y contribute each $5, the total contribution is $1380 hence the equation becomes

8x+5y=1380

<u>Combining equations</u>

Having the two simultaneous equations which are

x-y=10

8x+5y=1380

Solving the equations.

5x-5y=50

8x+5y=1380

------------------

13x=1430

x=1430/13=110

Therefore, 8th graders are 110. Since the 8th graders were 10 more than 7th graders, the 7th graders will be 110-10=100 students

To solve this system of equations by elimination, what operation could be used to eliminate the x-variable and find the value of
babymother [125]

Answer:

The value of y is y=\frac{42}{17}

Step-by-step explanation:

we have

4x+3y=6 -----> equation A

18x+5y=6 -----> equation B

To eliminate the x-variable and find the value of y Multiply the equation A by -18/4 both sides or multiply the equation B by -4/18 both sides

I choice

Multiply the equation A by -18/4 both sides

(-18/4)[4x+3y]=6*(-18/4)

-18x-13.5y=-27 ------> equation C

Adds equation B and equation C

18x+5y=6\\-18x-13.5y=-27\\-------\\5y-13.5y=6-27\\-8.5y=-21\\\\ y=\frac{42}{17}
