Answer:
50 + 25 = 75
50 - 25 = 25
The numbers are 50 and 25
Step-by-step explanation:
The sum of two numbers is 25 and their difference is 75. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 25. In other words, x plus y equals 25 and can be written as equation A:
x + y = 75
The difference between x and y is 75. In other words, x minus y equals 75 and can be written as equation B:
x - y = 75
Now solve equation B for x to get the revised equation B:
x - y = 25
x = 25 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 75
25 + y + y = 75
25 + 2y = 75
2y = 50
y = 25
Now we know y is 25. Which means that we can substitute y for 25 in equation A and solve for x:
x + y = 75
x + 25 = 75
X = 50
Therefore,
Sum: 50 + 25 = 75
Difference: 50 - 25 = 25

A car tire has a radius of 10.4 inches. What distance will the tire travel after 20 rotations?
Answer:
Distance traveled after 20 rotations = 1306.24 inches
Step-by-step explanation:
r = 10.4 inches
Distance traveled in one rotation = Circumference of the car tire
Circumference of the car tire = 2πr
= 2 * 3.14 * 10.4
= 65.312 inches
Distance traveled after 20 rotations = 65.312 * 20
= 1306.24 inches

In a case whereby In 1950, a U.S. population model was y = 151. (1.013)^t-1950 million people, where t is the year, the model predict the U.S. population would be 288 million in the year 2000.
What is population model ?Population models are mechanical theories that link alterations in population structure and density to responses at the individual level (life history features in eco-evolutionary theory or vital rates in demographic theory).
The model was given as y=151x(1.013)^t-1950
where the future time t = 2000
Then we can substitute the given year 2000 as the value of 't'
then we will have y=[151x(1.013)^(2000-1950)] = 288 million

Use the midpoint formula to solve the following: a segment ab has endpoints at a(2,9) and b(6,6) determine the coordinates of the midpoint leave your answer as (x,y) with space after the comma.
Solution
For this case the midpoint formula is given by:
\(M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\)For this case we have x1= 2, y1= 9 and x2= 6, y2=6

Given
In a recent year, the total sales at Restaurant A were $475,000 more than at Restaurant B. Total sales at the two stores were $550,000,000.
Let sales of one store be x
Equation,
475000 + x + x = 550,000,000
2x = 550,000,000 - 475000
2x = 549525000
x = 274762500
Sales of one store = $274762500
Sales of other store

Assume the required reserve ratio is 30 percent. All figures are in billions. If the commercial banking system actually loans the maximum amount it is able to lend, excess reserves will be reduced to
If the commercial banking system actually lends out the maximum amount it is able to lend, the excess reserves will be reduced to zero. This is because there will be no excess reserves held by the commercial banking system after lending out $9 billion.
Given that the required reserve ratio is 30 percent and all figures are in billions, the following table shows the total reserves, excess reserves, and required reserves:
Required reserve ratio 30% Checkable deposits $140Billion Reserves required (30% of checkable deposits)$42Billion Reserves held $51Billion Excess reserves held $9Billion Loans outstanding $109Billion Total Securities $100Billion Total Property $10Billion Total Assets $260Billion Stock shares $130Billion Total liabilities $130Billion Net worth (total assets - total liabilities) $130Billion.
Therefore, the total reserves held is $51 billion, and the reserves required is 30% of $140 billion, which is $42 billion.
This implies that the excess reserves are $9 billion.The maximum amount the commercial banking system can lend out is $51 billion minus $42 billion, which is $9 billion.
This indicates that if the commercial banking system actually lends out the maximum amount it is able to lend, the excess reserves will be reduced to zero. This is because there will be no excess reserves held by the commercial banking system after lending out $9 billion.

When an object is weighed on a scale, the number displayed may vary from the object’s actual weight by at most 0.4 pounds. The scale says the object weighs 125.8 pounds. Part A: Write an absolute value inequality that describes the range of the actual weight of the object. Use the variable w to represent the actual weight of the object. Part B: Solve the absolute value inequality for w. Express your answer as a compound inequality.
The compound inequality that represents the range of the actual weight of the object is 125.4 ≤ w ≤ 126.2.
Part A: The absolute value inequality that describes the range of the actual weight of the object is:
|w - 125.8| ≤ 0.4
Part B: To solve the absolute value inequality, we can break it down into two separate inequalities:
w - 125.8 ≤ 0.4 and - (w - 125.8) ≤ 0.4
Solving the first inequality:
w - 125.8 ≤ 0.4
Add 125.8 to both sides:
w ≤ 126.2
Solving the second inequality:
-(w - 125.8) ≤ 0.4
Multiply by -1 and distribute the negative sign:
-w + 125.8 ≤ 0.4
Subtract 125.8 from both sides:
-w ≤ -125.4
Divide by -1 (note that the inequality direction flips):
w ≥ 125.4
Combining the solutions, we have:
125.4 ≤ w ≤ 126.2
The object is 125.4 ≤ w ≤ 126.2.

A coin is about to be tossed 50 times. Determine the probability the 8th heads occurs on the 12th toss
Answer:
0.0806
Step-by-step explanation:
From the given information:
Number of toss = 50
The probability of having a head = 1/2 = 0.5
The Probability of 8th head occur on 12th toss can be computed as :
Pr(8th head occur on 12th toss) = Pr(7 heads in 11 toss) × P(8th head on 12th toss)
Pr(8th head occur on 12th toss) = C(11,7) × 0.5⁷ × (1 - 0.5)⁴ * 0.5
Pr(8th head occur on 12th toss) = \(\dfrac{11!}{7!(11-7)!}\) × 0.5⁷ × (1 - 0.5)⁴ × 0.5
Pr(8th head occur on 12th toss) = 0.0806
Answer:
The probability of 8th heads,
That is occurred on 12th toss.
Step-by-step explanation:
A coin is tossed 50 times.
There are two possible outcomes of occurring a head or tail.
Probability of occurring head = no.of head/ possible outcomes
= 1/2
Total number of tossing a coin= 50 times
Probability of 8th heads occurs on 12th toss:
12C8 (1/2)8 (1/2)9 (1/2)10 (1/2)11 (1/2)12
= 12C8 (1/2)8+9+10+11+12
= 12C8 (1/2)50
= 12C8 / 250
= 495 / 1125899906842624

Would you rather have a cup of ice cream that hold last a volume of 21.21 inches or a cone that has a radius of 1.5 inches and height of 3 inches?
Answer:
I will prefer the cone having volume 21.21 cubic inches.
Step-by-step explanation:
A cup of ice cream holds ice cream = 21.21 cubic inches
Since volume of a cone = Capacity of the cone to hold the ice cream
Volume of an another cone having radius (r) = 1.5 inches and height (h) = 3 inches will be,
V = \(\frac{1}{3}(\pi)(r^{2} )(h)\)
= \(\frac{1}{3}(\pi )(1.5)^{2}(3)\)
= 7.069
≈ 7.07 cubic inches
Since the volume of the second cone is less than the first cone, I will prefer the first cone with volume = 21.21 inches³
Given that a+b = 10 and a square - b square = 40 find the value of a-b
Answer:
the value of a - b is 4.
Step-by-step explanation:
We have been given the following two equations:
a + b = 10 ------------(1)
a² - b² = 40 -------(2)
We can factor the left-hand side of equation (2) using the difference of squares identity:
(a + b)(a - b) = 40
Substituting equation (1) into this equation, we get:
10(a - b) = 40
Dividing both sides by 10, we get:
a - b = 4
Therefore, the value of a - b is 4.
Step-by-step explanation:
if I understand this correctly :
a + b = 10
a² - b² = 40
(a² - b²) = (a + b)(a - b) = 40
10(a - b) = 40
(a - b) = 4

24.5%
35%
38%
Answer:
24.5%
Step-by-step explanation:
Given
P(Off-Campus) = 0.30
P(Part-Time Job | Off-Campus) = 0.62
P(Part-Time Job | On-Campus) = 0.65
Inferred
P(On-Campus) = 0.70
P(No Part-Time Job | Off-Campus) = 0.38
P(No Part-Time Job | On-Campus) = 0.35
Calculation
P(No Part-Time Job | On-Campus) = P(No Part-Time Job ∩ On-Campus)/P(On-Campus)
0.35 = P(No Part-Time Job ∩ On-Campus)/0.70
0.245 = P(No Part-Time Job ∩ On-Campus)
Therefore, 24.5% of students that live on campus do not have a part-time job.
