Answer: 615 ft²
<u>Step-by-step explanation:</u>
There are 4 walls - <em>assume that the floor and ceiling are not being painted.</em>
2 walls are 17 ft by 9 ft ⇒ 2(17)(9) = 306 ft²
The other 2 walls are 18 ft by 9 ft ⇒ 2(18)(9) = 324 ft²
1 window is 3.75 ft by 4 ft ⇒ 1(3.75)(4) = 15 ft²
2 walls + other 2 walls - 1 window ⇒ 306 + 324 - 15 = 615 ft²
Answer:
The mean is 28.3 or 28
I added it all and then divided it by how many different numbers there were.
1,545•.6=927 so 927 vanilla ice creams were sold
1 to left gives (x -1)^2
vertical stretch makes it 5(x - 1)^2
reflection in axis changes the sign to - :-
equation of new function is f(x) = -5(x - 1)^2
Answer:
3. 37
4. 59
5. 79
Step-by-step explanation:
All the angles of the triangle add up to 180°
3. 180-(31+112) = 37°
4. (4x-18)+(8x+7)+(5x+4) = 180
17x-7 = 180
17x = 187
x =11
we have found the x now we need to input it to find m∠z
5x+4
=5×11+4
=59°
5. A straight angle is 180° so if the outside angle is 129 the inside one will be 51°
(2x-3)+(x+9)+51 = 180
3x+57 = 180
3x = 123
x = 41
Now we need to find m∠L
2x-3
= 2×41-3
= 79°
