Lines A and B parallel lines cut by the transversal c. If the measure of angle 5 is 123, what is the measure of angle 1?
Jet001 [13]
123. angle 1 would be the same as angle 5, seeing as the lines are parallel. 5&1 are both on top on lines A & B AND on the same side of transversal

The volume of a paper weight in the shape of a square pyramid is 48 cm3. Find the measure of one side of the base, if the height
Ulleksa [173]

The measure of one side of the base = 4 cm

Formula for the volume of a square pyramid V=\frac{1}{3}\times a^2h

The area of the base of the pyramid = 16 cm²

Length of the side of the base of the pyramid = 4 cm

Solution:

Given data:

Volume of a square pyramid = 48 cm³

Height of the square pyramid = 9 cm

Formula for the volume of a square pyramid:

$V=\frac{1}{3}\times a^2h, where a is one side of the base and h is height.

Substitute volume and height in the formula,

$48=\frac{1}{3}\times a^2\times9

$48=a^2\times 3

Divide by 3 on both sides of the equation,

$16=a^2 – – – – (1)

Taking square root on both sides of the equation, we get

a = 4

One side of the base = 4 cm

Area of the base = side × side

It is already found in equation (1),

Area of the base = 16 cm²

Length of the side of the base of the pyramid = 4 cm.

HELP TIMED QUESTION !!!!<br> Simplify (5x^3y)^2(-2x^5y^1)
Liono4ka [1.6K]

Answer:

 ( -5•2x8y)

Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "^-1" was replaced by "^(-1)".

Equation at the end of step 1

 ((5•(x3))•(y2))•(0-(2x5•y(-1)))

Equation at the end of step

 (5x3 • y2) •  -2x5y(-1)

Multiplying exponential expressions :

3.1    x3 multiplied by x5 = x(3 + 5) = x8

Multiplying exponential expressions :

3.2    y2 multiplied by y(-1) = y(2 + (-1)) = y1 = y
