One of the ancient stone pyramids in Egypt has a square base that measures 140 m on each side. The height is 96 m. What is the v

miv72 [106K]

Volume of a pyramid = $\frac{1}{3}*base*height$

Given base is = 140 m

Given height is = 96 m

Volume = $\frac{1}{3}\times140\times96=4480$

Hence, volume of pyramid is 4480 m³

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 4, 29) and (x₂, y₂ ) = (0, 28) ← 2 ordered pairs from the table

m = $\frac{28-29}{0+4}$ = - $\frac{1}{4}$

The line crosses the y- axis at (0, 28 ) ⇒ c = 28

y = - $\frac{1}{4}$ x + 28 ← equation of line → D

Anvisha [2.4K]

Answer:

Step-by-step explanation:

Step 1:

0.5x - 3 = 2 - 0.75x Equation

Step 2:

1.25x - 3 = 2 Add 0.75x on both sides

Step 3:

1.25x = 5 Add 3 on both sides

Step 4:

5 ÷ 1.25 Divide

Step 5:

x = 4 Solution to x

Step 6:

2 × 4 Multiply to find answer of 2x

Answer:

2x = 8
