Answer: h=12.8in
a Base edge 15 in
V Volume 960 in³
Using the formula
V=a2h
3
Solving for h
h=3V
a2=3·960
152=12.8in
Step-by-step explanation:
Answer:
2-58
Step-by-step explanation:
total angles sum in a triangle= 180
180 = 68+ 54 + x
x= 180-(68+54)
x=180-122
x=58
Answer: There are 33 dimes and 17 quarters in my pocket.
Step-by-step explanation:
Step 1: To assign and label the variables.
Suppose,
The number of dimes= x
The number of quarters= y
Step 2: To write the system of equations.
Equation related to the total coins:
x + y = 50 equation 1
Equation related to the total value of the coins:
0.10x + 0.25y = 9.95 equation 2
Step 3: To solve the system of equations.
Multiply equation 1 by 0.10 and then subtract it from equation 2 to eliminate the variable, x.
0.10x + 0.25y – (0.10x + 0.10y)= 9.95 – 5
0.15y = 4.95
y= 33
So, x=50 - 33= 17
Step 4: Therefore, there are 33 dimes and 17 quarters in my pocket.

Answer:</h3>
<h3>C. In x = -7 </h3>
<h3>
Step-by-step explanation:</h3>
<h3>13 + Inx = 6</h3>
<h3>1. Subtract 13 from both sides</h3>
13 + Inx - 13 = 6 -13
<h3>2. Simplify </h3>
= In x = -7
<h3>Solution : </h3>
<h3>= In x = -7</h3>
