Answer:

16 degrees

Step-by-step explanation:

let the angle be 'x'

so, we can equate the given statements as:

6x - 21 = 4x + 11

6x - 4x = 11 + 21

2x = 32

x = 32/2 = 16 degrees

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet.

igomit [66]

Percentage error $=\frac{error}{actual measurement} \times 100$
Here error = 16 - 15.4 = 0.6
Therefore, percentage error $=\frac{0.6}{15.4} \times 100=0.039 \times 100$
=3.9%

The roof of a barn rises vertically 2.5 meters through the horizontal distance of 10 meters. What is the pitch (slope) of the ro

Lesechka [4]

Answer:

The pitch (slope) of the roof is $0.25$ or $25\%$

Step-by-step explanation:

we know that

The formula to calculate the slope is equal to

$m=\frac{y2-y1}{x2-x1}$

where

In this problem we have

${y2-y1}=2.5\ m$ -----> is the vertical distance (rises)

${x2-x1}=10\ m$ -----> is the horizontal distance (run)

substitute the values

$m=\frac{2.5}{10}=0.25$

convert to percentage form

$0.25*100=25\%$
