Builders are covering a wall that is 4 meters tall and 7 meters wide with bricks. They will cover the entire wall except for a s

marin [14]

Answer:

24 m^2

Step-by-step explanation:

There are two areas to consider here: first, the area of the wall, and second, the area of the window. We answer this question by finding these two areas and subtracting the area of the window from the area of the wall.

Wall area: (4 m)(7 m) = 28 m^2

Window area: (2 m)(2 m) = 4 m^2

Net area of wall, to be covered in brick:

28 m^2 - 4 m^2 = 24 m^2

3/5 with an exponent of 4

nordsb [41]

Step-by-step explanation:

$\text{If is}\ \dfrac{3}{5}^4,\ \text{then}\ \dfrac{3}{5}^4=\dfrac{3\cdot3\cdot3\cdot3}{5}=\dfrac{81}{5}=16\dfrac{1}{5}\\\\\text{If is}\ \left(\dfrac{3}{5}\right)^4=\left(\dfrac{3}{5}\right)\left(\dfrac{3}{5}\right)\left(\dfrac{3}{5}\right)\left(\dfrac{3}{5}\right)=\dfrac{3\cdot3\cdot3\cdot3}{5\cdot5\cdot5\cdot5}=\dfrac{81}{625}$

Lisa’s age is 4 years older than three times sammy’s Age. Lisa is 28 years old let s represent sammy’s Age

mel-nik [20]

Answer:

Sammy is 8 years old

Step-by-step explanation:

3s + 4 = 28 is the equation you need to use you have to get s on its own to find Sammy's age

3s + 4 = 28 subtract 4 from both sides

3s = 24 divide both sides by 3

s = 8 Sammy is 8 years old

Find the measures of two angles, one positive and one negative, that are coterminal with <img src="https://tex.z-dn.net/?f=%5Cfr

aleksandrvk [35]

Answer:

a. 11/5 pi; -9/5 pi

Step-by-step explanation:

Coterminal angles are those which have a common terminal side. For example 30° is coterminal with −330° and 390° (see figure).

From the example we can see that the following expressions must be fulfilled:

positive angle - reference angle = 360°

reference angle - negative angle = 360°

where positive angle is 390°, reference angle is 30° and negative angle is -330°. In this problem reference angle is pi/5. Also, we have to change 360° for its equivalent in radians, i. e., 2 pi. So,

positive angle - pi/5 = 2 pi

positive angle = 2 pi + pi/5

positive angle = 11/5 pi

pi/5 - negative angle = 2 pi

negative angle = pi/5 - 2 pi

negative angle = -9/5 pi
