Answer:
132 m².
Step-by-step explanation:
What's the surface area of each lateral face of this pyramid?
Each lateral face of this pyramid is a triangle, with
- a height of 8 meters
- on a base 6 meters.
The base of this pyramid is a square. As a result, all four lateral sides are congruent. The area of each of these triangle is thus
.
The base of this pyramid is a square. The length of a side of this square is 6 meters. The area of the base will be
.
Put the five faces together to get the total surface area of this square pyramid:
.
Theoretically, each letter should have the same probability of occurring since there are 15 of each. There are 5 letters that can be drawn, so there is a total of 75 balls, and each letter has a probability
of being drawn.
This means one would expect a theoretical frequency of
, i.e. any given letter should get drawn 250 times, which means the answer is D.

1. The formula for calculate the area of a rectangle, is:
A=LxW
A is the area of the rectangle
L is the length of the rectangle.
W is the widht of the rectangle
2. You have that:
-The<span> rectangular Corn Hole area has a width of 5 feet and a length of 10 feet, so:
L1=10 feet
W1=5 feet
- When</span> a uniform amount is added to each side (x), the area is increased to 84 feet². Then, you have a different length (L2) and a different width (W2):
3. The new length is:<span>
L2=L1+x+x
L2=L1+2x
L2=10+2x
4. The new width is:
W2=W1+x+x
W2=W1+2x
W2=5+2x
5. The new area is:
A2=84 feet</span>²<span>
6. Then, you have:
A=LxW
84</span>=(10+2x)(<span>5+2x)
7. When you apply the distributive property, you obtain a quadratic equation:
4x</span>²+30x-34=0
<span>
8. You can solve with by applyin the quadratic formula:
x=(-b±√(b^2-4ac))/2a
a=4
b=30
c=-34
9. Then, the answer is:
x=1 feet

Answer:
It's C
Step-by-step explanation:
Your graph should be this one, with both lines solid because, the X line, or red, has to be at least -1 or higher, and the Y line, or the blue, has to be +4 or higher
