Answer:
Not if you want it to be a positive number. You can but it will be a negative.

Answer:
14 days
Step-by-step explanation:
18 seconds on day 1
44-18=26
26/2=13 days
Day 1 +13 Additional days=14 days
We see that the area is 159 3/8 and the length is 18 3/4.
Because the area is the length*width, to find the width, we must divide the area by the length.
Think of it this way:
Divide l on both sides:
And w is what we're looking for.
So, divide 159 3/8 by 18 3/4.
You should get that the width is 8.5 feet :)
Silvia has to score a 101 to get an average of 90 for all four tests.
Explanation: 90=(86+81+92+x)/4
360=259+x
101=x
Answer:
152 squared cm
Step-by-step explanation:
You divide the figure into 2 shapes. A triangular pyramid, and a rectangular prism. Find the surface are of each, and add them together.
Triangular pyramid
1. Find surface area of one triangle and multiply by 4, since there are four of the congruent triangles.
5(height) times 4(base of triangle) divided by 2
You get 10, then multiply 10 by 4, because there are 4 congruent triangles.
Figure 1 = 40 cm2
Rectangular Prism
4 times 4 = 16 (base surface area)
6 times 4 = 24 (area of one side)
24 times 4 = 96 (surface area of all 4 sides)
96(surface area of all 4 sides) + 16(surface area of base) = 112
40(surface area of pyramid) + 112(surface area of prism) = 152 cm2
