7 in 7.8 is 100 times greater than 7 in 23.97.
What is place value ?As the name suggests place value is where the digit is being placed in decimal number system.
We can multiply both these numbers by 100 in that way we'll get rid of the decimal and it doesn't effect our answer.
Now 7.8 and 23.97 multiplied by 100 becomes 780 and 2397.
We can observe that 7 in 780 is in hundreds place and 7 in 2397 is in ones place.
∴ If we divide (100/1) = 100.
So, it is 100 times greater.

The difference between two numbers is 69. Four times the smaller is equal to 3 more than the larger. What are the numbers?
smaller number = y
larger number = x
x - y = 69
4y = x + 3
you can solve this using substitution
x = 69 + y
(isolating one of the variables)
4y = 69 + y + 3
(substituting 69 + y for x into the other equation)
4y = 72 + y
3y = 72
y = 24
(simplify)
x - 24 = 69
x = 93
(substituting 24 into one of the original equations)
solve the quadratic equation
Make sure the equations equal 0

You want to put a 2 inch thick layer of topsoil for a new 20 ft by 24 ft garden. The dirt store sells by the cubic yards. How many cubic yards will you need to order? The store only sells in increments of 1/4 cubic yards.
3.0 CUBIC YARDS I WILL NEED TO ORDER TO PUT A 2 INCH THICK LAYER OF TOPSOIL
HOW TO FIND VOLUME OF SOIL ?As a result, the problem gives you the volume of the space you are trying to fill with soil ( 20ft by 24ft by 2 in). Let's measure everything in feet first, and then we can measure the volume in yards. You may acquire a volume of approximately (rounding to two decimal places)80.00 cubic feet by converting 2 inches to feet, or 2/12. Then, to obtain your volume, multiply that by 20 times 24. Since there are 3 feet in 1 yard, we divide this volume in yards by 3, giving us 3.0 cubic yards. You will need 3.0 cubic yards if the business only sells in 1/4 cubic yard increments.
CALCULATIONV = (20')(24')(2'/12)
V = 80f[tex]t^{3}[/tex]
1 [tex]yd^{3}[/tex] = 27 [tex]ft3[/tex]
80[tex]ft3[/tex] / 27[tex]ft3[/tex] ≈ 3.0

283,000 newspaper copies will be distributed among the 13 cities evenly.
How is simple division calculation done?Out of the four basic mathematical operations, division is frequently regarded as the most challenging. Once we fully comprehend the procedure and guidelines, we can use a calculator without error to perform increasingly challenging calculations.
We can divide or "share" numbers using division to arrive at an answer. Take 10 ÷ 2 as an example. How would we arrive at the solution? (ten divided by two). This is equivalent to "sharing" 10 candies between 2 kids. The total quantity of candies that each child receives must be the same. The solution in this instance is 5.
No. of newspaper circulated a day = 3,679,000
No. of cities to be distributes among = 13
No. of newspaper a city will receive = 3,679,000/ 13

Which two inequalities can be used to find the solution to this absolute value inequality?
The two inequalities that can be used to find the solution are x-1 < 3 and x-1 > -3.
The given inequality is 3 + 2|x-1| < 9.
The absolute value |x-1| can be (x-1) or -(x-1).
We need to solve this inequality for this two cases.
So first if |x-1| = (x-1), then,
3 + 2|x-1| < 9
⇒ 3 + 2(x-1) < 9
⇒ 2(x-1) < 6
⇒ x-1 < 3
⇒ x < 4 is the solution.
Now if |x-1| = -(x-1), then,
3 + 2|x-1| < 9
⇒ 3 - 2(x-1) < 9
⇒ -2(x-1) < 6
⇒ -(x-1) < 3
⇒ x-1 > -3 [When multiplied with (-1), the inequality reverses]
⇒ x > -2 is the solution.
Going through these steps, we can conclude that the two inequalities that can be used to find the solution to the absolute value inequality,
3 + 2|x-1| < 9 are x-1 < 3 and x-1 > -3.

The solution of the given inequality |x - 7| + 8 < 11 is 4 < x < 10.
What is meant by the term inequality?In mathematics, an inequality is an interaction between two expressions as well as values which are not equitable to each other. Inequality results from a lack of balance.
Rule 1: Once inequalities are linked, they can be crossed. As a result, if an is greater than b and b is greater than c, a will indeed be greater than c as well.If a > b > c, a > c, we can skip b and get to the relationship between a and c directly.Rule 2: When you swap the values, this same sign reverses.If p > q, then q < pIf p < q, then q > pAs per the given relation;
|x - 7| + 8 < 11
Subtract both side by -8.
|x - 7| + 8 - 8 < 11 - 8
|x - 7| < 3
Removing modulus will give the relation as;
- 3 < x - 7 < 3
Add 7 on both side.
- 3 + 7 < x - 7 + 7 < 3 + 7

15. The weight of a trout varies jointly as its length and the square of its girth. One angler
caught a trout that weighed 10.5 pounds and measured 26 inches long with an 18-inch
girth. Find the weight of a trout that is 22 inches long with a 15-inch girth. (Girth is the
distance around the body of a fish.)
The weight of the trout is 6.17 pounds.
How to find the weight of the trout?
We know that the weight of a trout varies jointly as its length and the square of its girth.
If W is the weight, x is the length and y is the girth, then:
W = k*x*y^2
Where k is a constant.
We know that one trout with:
x = 26 in
y = 18in
Has a weight of 10.5, then we can write:
10.5 = k*(26)*(18)^2 = k*8,424
Solving for k we get:
10.5/8,424 = k
Then the equation is:
W = (10.5/8,424)*x*y^2
Now, our trout has:
x = 22 in
y = 15 in
Then the weight is:
W = (10.5/8,424)*22*15^2 = 6.17
The weight of the trout is 6.17 pounds.

A standard mortgage payment means paying back your loan amount and any interest that the bank stated at the time of giving the loan.
It can also include taxes and insurance with your monthly mortgage rate, but this can be calculated separately.
The equation takes into account your total loan payment with the monthly interest rate and the length of time you have to pay off your loan that is the time period. It gives you a fixed monthly mortgage rate.
