Answer:
60
Step-by-step explanation:
The answer is 60 because the equation u = 26 tells us u is 26
So we can plug in 26 into u + 34
It should look like this 26 + 34 and it equals 60

A=2piR
so 144pi=2piR
solve and you get R=72
so D= 144 ft
Answer:
The probability of selecting a black card or a 6 = 7/13
Step-by-step explanation:
In this question we have given two events. When two events can not occur at the same time,it is known as mutually exclusive event.
According to the question we need to find out the probability of black card or 6. So we can write it as:
P(black card or 6):
The probability of selecting a black card = 26/52
The probability of selecting a 6 = 4/52
And the probability of selecting both = 2/52.
So we will apply the formula of compound probability:
P(black card or 6)=P(black card)+P(6)-P(black card and 6)
Now substitute the values:
P(black card or 6)= 26/52+4/52-2/52
P(black card or 6)=26+4-2/52
P(black card or 6)=30-2/52
P(black card or 6)=28/52
P(black card or 6)=7/13.
Hence the probability of selecting a black card or a 6 = 7/13 ....
The expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x
<h3>How to determine the
expression represents the
number of packages of
mulch that will be needed to cover both rounded ends?</h3>
The given parameters are:
Area covered = 300 square feet
Number of ends = 2
So, the total surface area is:
Total surface area = Area covered * Number of ends
This gives
Total surface area = 300 * 2
Total surface area = 600 square feet
Let the area covered by each package of mulch be x.
So, the number of mulch is
Number = Area covered/area covered by each
This gives
Number = 600/x
Hence, the expression represents the number of packages of mulch that will be needed to cover both rounded ends is 600/x
