Answer:
the area is 110. the formula for a trapezoid is <em>A</em><em>=</em><em> </em><em>a</em><em>+</em><em>b</em><em>/</em><em>2</em><em> </em><em>×</em><em> </em><em>h</em><em>.</em><em> </em>
<em>A</em><em>=</em><em> </em><em>a</em><em>+</em><em>b</em><em>/</em><em>2</em><em> </em><em>×</em><em>h</em><em>=</em><em> </em><em>A</em><em>=</em><em> </em><em>9</em><em>+</em><em>1</em><em>3</em><em>/</em><em>2</em><em>×</em><em>1</em><em>0</em><em>=</em><em>1</em><em>1</em><em>0</em>

Find out How many minutes in a year which is 525600 then divide that by 3,000,000 which makes 5.7077 so rounded is 6.
Answer:
B= (-1, 7)
Step-by-step explanation:
Midpoint formula is X1 plus X2, then divided by 2. So, because the midpoint is given you work backwards. So for the x value do (-3 + x) divided by 2 equals -2 and solve for x and you do the same thing for the Y value
Answer:
c + d = 400
0.2c + 0.5d = 156
Step-by-step explanation:
Let
c = number of liters of 20% acid solution
d = number of liters of 50% acid solution.
c + d = 400 (1)
0.2c + 0.5d = 400(0.39)
0.2c + 0.5d = 156 (2)
From (1)
c = 400 - d
Substitute c = 400 - d into (2)
0.2c + 0.5d = 156 (2)
0.2(400 - d) + 0.5d = 156
80 - 0.2d + 0.5d = 156
- 0.2d + 0.5d = 156 - 80
0.3d = 76
d = 76/0.3
d = 253.33 liters
Substitute d = 253.33 into (1)
c + d = 400
c + 253.33 = 400
c = 400 - 253.33
c = 146.67 liters
