8. A pyramid has a volume of 8 cubic feet. The height is 2 feet. The base is rectangular. Give possible dimensions for the lengt

jeka57 [31]

Answer:

base = 12 ft²

The base could be 3 ft x 4 ft, 6 ft x 2 ft, etc. (any numbers multiplied together = 12)

Step-by-step explanation:

volume = 1/3bh

8 = 1/3b(2)

multiply both sides of the equation by 3:

24 = 2b

b = 12 ft²

On the scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is

baherus [9]

Answer:

$I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

Step-by-step explanation:

Let I represent inches and F represent feet.

We have been given that on he scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is 16 feet.

We will use proportions to solve our given problem as:

$\frac{\text{Length on scale}}{\text{Actual length}}=\frac{6}{16}$

$\frac{I}{F}=\frac{6}{16}$

Now, let us solve for $I$ .

$I=\frac{6}{16}\cdot F$

$I=\frac{3}{8}\cdot F$

Now, let us solve our equation for F.

$I\cdot\frac{8}{3}=\frac{8}{3}\cdot\frac{3}{8}\cdot F$

$\frac{8}{3}\cdot I= F$

$F = \frac{8}{3}\cdot I$

Therefore, our required equations would be $I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

Which is the solution to the system of equations?

Answer:

D. (-1, 3/2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

Brackets

Exponents

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality

<u>Algebra I</u>

Coordinates (x, y)
Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define System</u>

4x + 2y = -1

3x + 4y = 3

<u>Step 2: Rewrite System</u>

4x + 2y = -1

[Multiplication Property of Equality] Multiply -2 on both sides: -2(4x + 2y) = 2
[Distributive Property] Distribute -2 on both sides: -8x - 4y = 2

<u>Step 3: Redefine Systems</u>

-8x - 4y = 2

3x + 4y = 3

<u>Step 4: Solve for </u><em><u>x</u></em>

Combine equations: -5x = 5
[Division Property of Equality] Divide -5 on both sides: x = -1

<u>Step 5: Solve for </u><em><u>y</u></em>

Substitute in <em>x</em> [Original Equation]: 3(-1) + 4y = 3
Multiply: -3 + 4y = 3
[Addition Property of Equality] Add 3 on both sides: 4y = 6
[Division Property of Equality] Divide 4 on both sides: y = 3/2
