Answer:
315
Step-by-step explanation:
No. of girls be g
No. of boys be b
g= 180
g/b = 4/3
b = 3g/4
b= 3(180/4)
b= 3*45
b= 135
.
Find b+g
= 135 + 180
= 315
<h3>Answer:</h3>
$34,500
<h3>Explanation:</h3>
23% of $150,000 = 0.23×$150,000 = $34,500
_____
<em>Comment on percentages</em>
The % symbol is a shorthand way to write /100. Thus 23% = 23/100 = 0.23. (Both the fraction and the decimal are pronounced "twenty-three hundredths.")
The liters in the tank when it is filled to a height of 3.70 is 5,580 liters
The liters that needs to be added to 100% capacity is 480 liters
<h3>What is the volume?</h3>
A right circular cone is a three dimensional object has a flat circular base that tapers to a vertex. The volume of a right circular cone is the amount of space in the right circular cone.
Volume of a cone = 1/3(πr²h)
Where:
- π = pi = 3.14
- r = radius
- h = height
Volume of the right circular cone when its filled to a height of 3.70 = 1/3 x 3.14 x 3.70 x 1.20² = 5.58 m³
5.58 x 1000 = 5,580 liters
Volume of the right circular cone when it is full = 1/3 x 3.14 x 4 x 1.20² = 6.03 m³
6.03 x 1000 = 6030 liters
Liters that needs to be added to 100% capacity = 6030 liters - 5,580 liters = 480 liters

Answer:
12 feet and 6inches ..................
Answer:
Step-by-step explanation:
We need to find the value of the below expression i.e.
when a = 2 and b = 1.
So,
Put a = 2 and b = 1 in the above expression. So,
Hence, the value of the expression is equal to 3.
