1. use the formula for the area of a trapezoid A=h ( b1+b2/2 ) where A is area, b1 and b2 are the length of the bases and h is the height, to answer the question. how many square feet of grass are there on a trapezoid field with a height of 75 ft based of 125 ft and 81 ft ?
a. 725 ft^2 **
b. 1025 ft^2
c. 7725 ft^2
d. 15,450 ft^2
2. order the following numbers from least to greatest; 2/5 , 0.7 , 9/2 , root 16
a. 0.7 , 9/2 , 2/5 , root 16
b. 2/5 , 0.7 , 9/2 , root 16
c. 0.7 , 2/5 , 9/2 , root 16 **
d. 2/5 , 0.7 , root 16 , 9/2
can you explain to me how to do this i don’t understand
Follow the directions in the first one.
1. To find the area of the trapezoid field, we can use the formula A = h * (b1 + b2) / 2, where A represents the area, b1 and b2 are the lengths of the bases, and h is the height.
In this case, we are given that the height (h) is 75 ft, the first base (b1) is 125 ft, and the second base (b2) is 81 ft. Plugging these values into the formula, we get:
A = 75 * (125 + 81) / 2
A = 75 * 206 / 2
A = 15,450 / 2
A = 7,725 ft^2
Therefore, the answer is c. 7725 ft^2.
2. To order the numbers from least to greatest, we can compare them. Let's consider the given numbers:
2/5, 0.7, 9/2, √16
First, we simplify the numbers and convert any fractions or radicals if possible:
2/5 = 0.4
√16 = 4 (since the square root of 16 is 4)
Now, let's order the numbers:
0.4, 0.7, 4, 9/2
Comparing these numbers, we see that 0.4 is the least, followed by 0.7, 4, and 9/2.
Therefore, the answer is c. 0.7, 2/5, 9/2, √16.
1. (a) is off by a factor of about 10. Better check again how you did it.
2.
2/4 = 0.4
9/2 = 4.5
