Answer:
Step-by-step explanation:
So, formula to be used is:
Average area of cross section is = volume/distance between plates.
Volume = 4343/22 = 197.4 square feet.
Answer:
80.67 hours
Step-by-step explanation:
Data provided in the question:
The number of weekly hours worked :
78 85 82 79 77 82 81 82 81 81 82 78
total number of observations = 12
Now,
Mean = (Sum of all the data values) ÷ (Total number of data values)
or
Mean = ( 78 + 85 + 82 + 79 + 77 + 82 + 81 + 82 + 81 + 81 + 82 + 78 ) ÷ 12
or
Mean = 968 ÷ 12
or Mean = 80.67 hours

Answer:
<u>The measure of the arc CD = 64°</u>
Step-by-step explanation:
It is required to find the measure of the arc CD in degrees.
So, as shown at the graph
BE and AD are are diameters of circle P
And ∠APE is a right angle ⇒ ∠APE = 90°
So, BE⊥AD
And so, ∠BPE = 90° ⇒(1)
But it is given: ∠BPE = (33k-9)° ⇒(2)
From (1) and (2)
∴ 33k - 9 = 90
∴ 33k = 90 + 9 = 99
∴ k = 99/33 = 3
The measure of the arc CD = ∠CPD = 20k + 4
By substitution with k
<u>∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°</u>
Answer:
0.16 gallons of paint are used on each piece of furniture.
The answer lies between the whole numbers 0 and 1.
Step-by-step explanation:
we know that
Four gallons of paint are used to paint 20 chairs and 5 small tables.
if each chair and table used the same amount of paint
then
sum the total pieces of furniture
20+5=25 pieces
Find the unit rate
Divide the total gallons of paint used by the total pieces

therefore
0.16 gallons of paint are used on each piece of furniture.
The answer lies between the whole numbers 0 and 1.
