Answer:
ANSWER BELOW
Step-by-step explanation:
If the door is 9 x 2 ft (18 sq ft):
12 x 18 = 216 sq ft. (Front face including the door)
216 sq ft - 18 sq ft = 198 (Front face not including the roof or door)
For the roof, the formula is h b/2:
So if the height is 4 and the base is 18, the area of the roof is 36.
To find the total area, you must add the area of the front face and the roof (without the door).
198 + 36 = 234 sq ft

Answer: 248 miles</h3>
======================================================
Work Shown:
1 hr, 30 min = 1 hr + 30/60 hr
1 hr, 30 min = 1 hr + 0.5 hr
1 hr, 30 min = 1.5 hr
The driver travels 93 miles in 1.5 hours, so his speed is
rate = distance/time
r = d/t
r = 93/1.5
r = 62 mph
In four hours, he travels
d = r*t
d = 62*4
d = 248 miles
---------------
An alternative method is shown below
(93 miles)/(1.5 hrs) = (x miles)/(4 hours)
93/1.5 = x/4
93*4 = 1.5*x ..... cross multiply
372 = 1.5x
1.5x = 372
x = 372/1.5
x = 248
Answer:
4. A
5. B
Step-by-step explanation:
4. I'll solve question four first:
The two marked points on the line are (-2, -3)&(2, 5). Using the formula to find slope(y2-y1/x2-x1), substitute in the points.
5--3/2--2 or 8/4;simplified to 2/1 or 2.
Now use point-slope form: y-y1 = m(x-x1)
y--3 = 2(x--2): Substitute in the values of y1, m, and x1.
y+3 = 2x + 4: Distribute.
y = 2x + 1: Subtract three from both sides.
5. Do the same for question 5.
The first point is (-4, 2), the second point is (4, -1).
-1-2/4--4; -3/8.
Now use point-slope form:
y-2 = -3/8x -12/8: Substitute in the values of x1, y1, m, and distribute the slope to the parentheses.
y = -3/8x + 1/2
