A customer pays $7.14 for oranges and $5.16 for pears. How many pounds of fruit does the
customer buy?
Answer:
10 pounds
Step-by-step explanation:
Weight of oranges bought = $7.14 ÷ $1.19
= 6 pounds
Weight of pears bought = $5.16 ÷ $1.29
= 4 pounds
Total weight of fruits bought = 6 + 4
= 10 pounds

If you add two to twice a number, the result is twelve. What is the number?
The unknown number will be 5 if we add two to twice a number, the result is twelve.
Let the unknown number be x.
Then the twice of the known number be 2x.
According to the given question.
If we add two to twice a unknown number, the result is twelve.
So, from the given scenario we can say that
2 + 2x = 12
Now we have a linear equation in one variable 2 + 2x = 12 and we have to solve it for x which gives us the unknown number.
Therefore,
2 + 2x = 12
⇒ 2x = 12 - 2 (subtracting 2 from both the sides)
⇒ 2x = 10
⇒ x = 10/2
⇒ x = 5
Hence, the unknown number will be 5 if we add two to twice a number, the result is twelve.

Given that line CD is a perpendicular bisector of triangle ABC, if side AB has a length of 6 and side AC has a length of 12 what is the length of side CD? Write your answer to the
nearest hundredth ie 179.50.
Using the Pythagorean Theorem, the length of CD, to the nearest hundredth, is: 11.62.
How to Apply the Pythagorean Theorem?The measure of the longest side of a right triangle when squared will be equal to the sum of the squares of the other smaller sides of the right triangle.
Given the following:
Side AB = 6
Side AC = 12
Based on the perpendicular bisector theorem, AD = 1/2(AB) = 1/2(6) = 3.
Using the Pythagorean theorem, we have:
Length of CD = √(AC² - AD²)
Length of CD = √(12² - 3²)
Length of CD = √(144 - 9)
Length of CD = 11.62
Thus, using the Pythagorean Theorem, the length of CD, to the nearest hundredth, is: 11.62.

Answer:
the two prime factors is (113) (97)
Step-by-step explanation:
The computation of the two prime factors is is shown below:
The given expression is
105^2 - 8^2
Here we used the formula i.e.
a^2 - b^2 = (a + b) (a - b)
where,
a = 105
b = 8
Now
= (105 + 8) (105 - 8)
= (113) (97)
Hence, the two prime factors in descending order is (113) (97)

Yancey Smith works part-time as a sales assistant. Last week
he earned $240.00. This week he earned $325.00. Yancey is
single and claims 2 allowances. Using the percentage method,
how much more will be withheld this week for federal
income tax?
The required amount to be held this week for federal tax is $12.75.
Here,
Last week's earnings = $240
Difference with marked amount = $240 - $195 = $45
This comes under type 2
So tax = 14 + 15% of 45
tax = 14.40 + 6.75
tax = $21.15
This week's earnings = $325
The difference with marked amount = $325 - $195 = 130
Tax = 14 + 15% of 130
Tax = 14.40 + 19.5
Tax = 33.9
the amount held this week = 33.9 - 21.15
= $12.75
Thus, the required amount to be held this week for federal tax is $12.75.

What is defined as the compound events?A compound event is one that includes more than one sample point.
Compound events are slightly more complicated than simple events. Such events involve the possibility of multiple events occurring concurrently.The probabilities of the both events are multiplied to find compound events.For the given question, we must multiply the probability of selecting a green marble and going to roll an even number.
The total marbles contained in the jar are;
10 red marbles, 8 green marbles, 5 blue marbles, and 6 white marblesThe formula for probability is;
P(event) = favourable outcome/total outcome
There are six sides to a die/number cube. Each has a 1/6 chance of happening.
There are three even numbers in this situation. The probability of an even number is:
P(even) = 3/6 = 1/2
The probability of selecting the green marble;
P (green marble) = 8/29
We must now determine the likelihood of both events occurring. So multiply both probabilities to get the following answer:
8/29 × 1/2 = 4/29
The probability of selecting a green marble as well as rolling an even number are 4/29.

Suppose that fund-raisers at a university call recent graduates to request donations for campus outreach programs. They report the following information for last year's graduates.
Size of donation $0 $10 $25 $50
Proportion of call 0.40 0.30 0.25 0.05
Three attempts were made to contact each graduate. A donation of $0 was recorded both for those who were contacted but who declined to make a donation and for those who were not reached in three attempts. Consider the variable
x = amount
of donation for the population of last year's graduates of this university.
(a) Write a few sentences describing what you think you might see if the value of x was observed for each of 1000 graduates.
You would expect roughly of the graduates to donate nothing, roughly to donate $10, roughly to donate $25, and roughly to donate $50. The frequencies would be close to, but not exactly, these values. The four frequencies would add to .
