Answer:
- n + q = 25
- 0.05n + 0.25q = 4.05
Step-by-step explanation:
<em>Two equations</em> are required to represent this problem as posed.
1. An equation for the number of coins:
n + q = 25
2. An equation for the value of the coins:
0.05n + 0.25q = 4.05
Answer:
B
Step-by-step explanation:
|15-12|/4 = 3/4
|(-21+9)/8| = |-12/8| = 12/8 = 3/2 (Simply)
3/4 - 3/2 = -3/4
So the answer is B.
Answer:
4 ducks
12 chickens
Step-by-step explanation:
Ducks to Chicken (ducks : chicken) ratio
= 1 : 3
Ducks to Chicken ratio, if chickens = 12
= ? : 12
1 : 3 = ? : 12
Find the scale factor of the ratios by dividing the number of chickens to the ratio of chickens.
12 ÷ 3 = 4
To find the number of ducks, multiply the ratio of ducks by the scale factor.
1 X 4 = 4
Therefore, there are 4 ducks and 12 chickens on the farm.
Ratios can also be written like fractions. Use this to check the answer:
1/3 = 4/12
4/12 can be reduced by dividing both the top and the bottom by 4.
4/4 = 1 Same as original ratio top
12/4 = 3 Same as original ratio bottom
Answer:
678.24 in³
Step-by-step explanation:
radius r = 6 in
height h = 6 in
volume V = 678.24 in³
lateral surface area L = 226.08 in²
top surface area T = 113.04 in²
base surface area B = 113.04 in²
total surface area A = 452.16 in²
In Terms of Pi π
volume V = 216 π in³
lateral surface area L = 72 π in²
top surface area T = 36 π in²
base surface area B = 36 π in²
total surface area A = 144 π in²
Agenda: r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.1415926535898
√ = square root
Calculate volume of a cylinder:
V = πr²h
There is no way to know unless you were given a row number or number of seats in a row
