If all the books on a shelf with fewer than 45 books were put into piles of five books each, no books would remain. If the same book were put into piles of seven books each, two books would remain. What is the greatest number of books that could be on the shelf?
Answers
Answer:
Hence the greatest number of books that could be on the shelf is 30.
Step-by-step explanation:
Step 1:-
Here the given number of books is m,
m < 45.
If they are arranged into piles of five books, each no books would remain.
m is divisible by 5.
The last digit of m would be 5 or 0.
The same number of books, when arranged with piles of 7 books each, two books remain.
m-2 is divisible by 7.
Step 2:-
The last digit of m is 5 or 0.
m-2 will have the last digit 3 or 8.
Multiples of 7 are 7,14,21,28,35, 42;
among which only number 28 has the last digit 8 or 3.
m - 2 = 28
m = 30
The greatest number of books that could be on the shelf is 30.

tan = opposite/adjacent.
From, The given diagram, With respect to the reference unknown angle,
the opposite side is 4 units and the hypotenuse is 16 units.
We know, sin = opposite/hypotenuse.
Therefore, sinФ = 4/16.

[tex]\frac{3}{4} x \frac{8}{3} =2[/tex]
2
Step-by-step explanation:
3/4 x 2 2/3 =
Convert 2 2/3 into a improper fraction!
Step 1. Multiply denominator by whole number.
2 2/3 = 3 • 2
Step 2. Add the numerator to the expression!
2 2/3 = 3 • 2 + 2
Step 3. Add the denominator after the expression.
2 2/3 = 3 • 2 + 2 / 3
Step 4. Solve
2 2/3 = 6 + 2 / 3
2 2/3 = 8 / 3
______________________________
Now instead of using 2 2/3 we are going to use 8/3!
Then we can start multiplying the two fractions (3/4 x 8/3)
Step 1. Multiply the numerator by numerator over denominator by denominator!
3/4 x 8/3 = 3 • 8/4 • 3
Step 2. Solve
3/4 x 8/3 = 24/12
Simplify 24/12
24/12 = 2
An amount of 960.00 was contributed equally by 80 students. If 714.00 was contributed equally by 68 girls and the remains was contributed equally by the boys,how much did each (A) girl contribute ( B)boy contribute
Answers
Answer:
Amount each girl contributed = 10.5
Amount each boy contributed = 16.83
Step-by-step explanation:
Total amount contributed = 916.00
Total student who contributed = 80
Number of girls = 68
Number of boys = 80 - 68
= 12
Amount contributed by 68 girls = 714.00
Amount each girl contributed = 714.00 / 68
= 10.5
Amount each girl contributed = 10.50
Amount contributed by boys = Total amount contributed - Amount contributed by 68 girls
= 916.00 - 714.00
= 202.00
Amount each boy contributed = 202.00/12
= 16.83
Amount each boy contributed = 16.83

The ordered pair are (-5/3, 0) and (0, 5)
Given the equation y = 3x + 5
To get the ordered pair of the equation, we will find the x and y-intercept
The x-intercept of the equation occur at y = 0
0 = 3x + 5
-3x = 5
x = -5/3
Hence the ordered pair of the solution is (-5/3, 0)
The y-intercept of the equation occur at x = 0
y = 3(0) + 5
y = 0 + 5
y = 5
Hence the ordered pair of the solution is (0, 5)

25) A father is twice as old as his son. The sum oth of the ages is 99 years. Find their ages.
Answers
Answer:
If the son’s age is x, the father’s age is 2x.
If the son’s age is x, the father’s age is 2x.Ten years ago:
If the son’s age is x, the father’s age is 2x.Ten years ago:(x - 10) + (2x - 10) = 52
If the son’s age is x, the father’s age is 2x.Ten years ago:(x - 10) + (2x - 10) = 523x + 20 = 52
If the son’s age is x, the father’s age is 2x.Ten years ago:(x - 10) + (2x - 10) = 523x + 20 = 523x = 72
If the son’s age is x, the father’s age is 2x.Ten years ago:(x - 10) + (2x - 10) = 523x + 20 = 523x = 72x = 24
If the son’s age is x, the father’s age is 2x.Ten years ago:(x - 10) + (2x - 10) = 523x + 20 = 523x = 72x = 242x = 48
If the son’s age is x, the father’s age is 2x.Ten years ago:(x - 10) + (2x - 10) = 523x + 20 = 523x = 72x = 242x = 48So the son’s age is 24 and the father’s is 48. Ten years ago, they were 14 and 38, which adds up to 52.

Answers
Answer:
x=[tex]\frac{y+1}{7}[/tex]
Step-by-step explanation:
Hi there!
We want to make x the subject of the formula, which means to solve the formula for x
Here is the given formula:
y=7x-1
Our ultimate goal is to isolate x onto one side
Start by subtracting 7x from both sides
y-7x=-1
Subtract y from both sides to remove it from the left side
-7x=-y-1
Divide both sides by 7
x=[tex]\frac{-y-1}{-7}[/tex]
Simplify (factor -1 out of the numerator and denominator, then cancel it out)
x=[tex]\frac{-1(y+1)}{(-1)(7)}[/tex]
x=[tex]\frac{y+1}{7}[/tex]
Hope this helps!
Answer:
x = 1/7(y+1)
or
x = 1/7 y + 1/7
Step-by-step explanation:
y= 7x-1
Solve for x
Add 1 to each side
y+1 = 7x-1+1
y+1 = 7x
Divide each side by 7
1/7(y+1) = 7x/7
1/7y + 1/7 =x

This is a right triangle trig problem. The height of the tree is the height of the triangle, and the length of the wire is the hypotenuse of the triangle. Using Pythagorean's Theorem, we can find the length of the base, which is how far he must secure the bottom of the wire from the base of the tree.

Sarah has saved $150. She wants to double the amount she saves each month. As an incentive, Sarah's grandma says if she saves that amount, she will give her an additional $50 each month. What is the recursive sequence formula and first term for Sarah’s savings
Answers
A recursive relation is a relation that defines the terms in a sequence with the previous terms.
Here, the recursive relation will be:
[tex]A_n = 2*A_{n - 1} + $50[/tex]
A₁ = $150.
We know that:
Sarah has saved $150 at the moment.
She wants to double the amount that she saves each month, so the next month she needs to save 2*$150 = $300
And if she saves the $300, then her grandma will give her another $50.
Then, if the previous month Sarah saved A, then the next month she will get the double of A plus $50, which is:
2*A + $50
Then the recursive relation is just:
[tex]A_n = 2*A_{n - 1} + $50[/tex]
Where Aₙ is the amount that she saves in the n-th month, and the first term of the sequence is the initial amount that she saved, so we have:
A₁ = $150.
