If the mean of A and B is 20 , the mean of B and C and the mean of A,B and C us 18 . What is the mwan of A and C
Answer:
the mean of A and C is 10
Step-by-step explanation:
Given that
The mean of A and B is 20
The mean of B and C is 24
And, the mean of A, B and C is 18
We need to find out the mean of A and C
Since the mean of A and B is 20
So, a + b = 20 × 2
= 40
Likewise for B and C it is 48
And, for A, B and C, it is 54
So,
a + b = 40
b + c = 48
a + b + c = 54
So if we put the value of b + c in the above equation
a + 48 = 54
a = 6
b = 34
c = 14
Now the mean of the A and C is
= (6 + 14) ÷ 2
= 10
Hence, the mean of A and C is 10

A school has an aquarium in each room. Each aquarium has 2 catfish for every 3 angelfish. How many fish are in an aquarium that has 6 catfish?
Answer:
15
Step-by-step explanation:
2:3 ratio
if there is 2 catfish in a tank, in order to reach 6 catfish, we need 3 tanks
therefore, 3*3=9, 9 is the amount of angel fish
6+9=15
In circle J with m \angle HJK= 50m∠HJK=50 and HJ=16HJ=16 units, find the length of arc HK. Round to the nearest hundredth.
Answer:
13.96
Step-by-step explanation:
length of an arc = theta/360 * 2πr
Given
m<HJK = 50
HJ = 16units
Required
length of arc HK
arc HK = 50/360 * 2(3.14)(16)
arc HK = 5/36 * 100.48
arc HK = 502.4/36
arcHK = 13.96
hence the length of arcHK to nearest hundredth is 13.96

Answer:
h = 3 cm
Step-by-step explanation:
The volume (V) of a rectangular prism is calculated as
V = Ah ( A is the area of the base and h the height )
Here V = 36 and A = 6 × 2 = 12 cm² , then
12h = 36 ( divide both sides by 12 )
h = 3
Answer: 3 cm
Step-by-step explanation:
The formula to solve the volume of a rectangular prism is V = l x w x h
Where V is volume, l is length, w is width, and h is height
Givens are, Volume = 36 cm3
length = 6 cm
width = 2 cm
Now, we will plug in the numbers to the formula
36 cm3 = 6cm x 2cm x h
36 cm3 = 12 cm2 x h
divide 12cm2 on both sides
36cm3/12cm3 = h
h = 3cm

To solve the equation 34x=15, Abby multiplied both sides by ¾ and got a solution of x=1114. Explain the error that Abby made and then find the correct value of x.
Answer:
x = 20
Step-by-step explanation:
3/4x = 15
Abby's calculation:
3/4x = 15
Multiply both sides by 3/4
x = 1114
Abby's error was multiplying both sides by 3/4 instead of dividing both sides by 3/4 to get the value of x
Correct calculation:
3/4x = 15
Divide both sides by 3/4
3/4x ÷ 3/4 = 15 ÷ 3/4
x = 15 × 4/3
x = 60/3
x = 20
Check:
3/4x = 15
3/4*20
= (3*20) / 4
= 60/4
= 15
3/4*20 = 15

Rose uses 8.3 pints of white paint and blue paint to paint her bedroom walls. 3 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer: Rose used 2.075 pints of blue paint for her bedroom walls
Step-by-step explanation:
Amount of white and blue paint used for bedroom walls=8.3 pints
Amount of white paint used =3/4 x8.3 pints =6.225 pints
Amount of blue paint used = Amount of white and blue paint used for bedroom walls-Amount of white paint used
8.3 pints - 6.225 pints=2.075 pints
