Answer:
B) 171 units^2
Step-by-step explanation:
The area is given by the formula ...
A = 1/2(b1 +b2)h
Filling in the given base and height values, we find the area to be ...
A = 1/2(23 +15)(9) = (19)(9) = 171 . . . square units

You can select the correct answer choice simply on the basis of "reasonableness." If this were a 9×15 rectangle, its area would be 9×15 = 135 square units, more than 85.5. You know its area is less than a 9×23 rectangle, so is less than 9×23 = 207 square units. Only one answer choice is a value between 135 and 207.

Multiplication by 9 is not so hard. It is multiplication by 10-1:
15×9 = 15×(10 -1) = 150 -15 = 135
1 1/2 divided by 1/2 = 3
So each cup would be 3
So therefore you would multiply by 3 I believe idk and then you will get 9
So 9 cups would fill the container
The answer b= 2h
the angle opposite to its base is a
so sina = b/2h= b/b=1
the answer is <span>b) 1</span>

The correct question is:
Using the digits 1 to 9 at most one time each place a digit in each box to create an equation where x is a negative value solve your equation to prove your answer.
__x + __ = __
Answer:
1. 9x + 8 = 1
2. 7x + 6 = 2
3. 5x + 4 = 3
Step-by-step explanation:
1. 9x + 8 = 1
Subtract 8 from both sides
9x = 1 - 8
9x = -7
Divide both sides by 9
x = -7/9
2. 7x + 6 = 2
Subtract 6 from both sides
7x = 2 - 6
7x = -4
Divide both sides by 7
x = -4/7
3. 5x + 4 = 3
Subtract 4 from both sides
5x = 3 - 4
5x = -1
Divide both sides by 5
x = -1/5
