A math book consists of two sections: arithmetic and geometry in the ratio 5:3. How much of each type of content will be needed to make a book of 480 pages?
Answer:
As the ratio is 5:3, it totals 8 parts. I would do 480 divided by 8 to get the number of pages per part, then multiply that number into the ratio.
480 / 8 = 60
The value of each part being 60 put into the ratio 5:3 = 60x5 : 60x3
Which gives your answer.

Answer:
x = 7
Step-by-step explanation:
Given
4(5x - 2) = 2(9x + 3) ← distribute parenthesis on both sides
20x - 8 = 18x + 6 ( subtract 18x from both sides )
2x - 8 = 6 ( add 8 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7

Answer:
560 +32x
Step-by-step explanation:
There are a number of ways the area can be subdivided. In order to minimize the number of expressions involving x, we choose to divide it this way:
Create a rectangle 52 yd by 40 yd that encloses the figure along with the empty space above the left side of the figure.
Subtract a rectangle whose dimensions are (40-x) by (52 -20) in the upper left corner of the previous rectangle.
Subtract a rectangle whose dimensions are 10 by 24 in the center of the figure.
Then the total area of the parking lot is ...
52·40 -(40-x)(32) -10·24 = 2080 -1280 +32x -240 = 560 +32x
The area of the parking lot is 560+32x square yards.

What is the measure of the remaining angle?
Enter the correct answer in the box.
Answer:
30+45+x=180(sum of all angles of triangle is equal to 180 degree)
75+x=180
x=180-75
x=105
The measure of the third interior angle is 105°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We also know that the sum of all the interior angles of a triangle is 180°.
Given, Two angles of a triangle have measures of 30° and 45°, assuming the third angle to be x.
∴ 30° + 45° + x = 180°.
x + 75° = 180°.
x = 180° - 75°.
x = 105°.
So, the measure of the third angle is 105°.

The second of three numbers is 11
less than the first. The third number is
5 less than the second. If the first
number is twice as large as the third,
find the three numbers.
Answer:The sum of three numbers is 112.
a+b+c=112
The second number is 5 times the first.
b=5a
so a+5a+c=112
6a+c=112
The third number is 20 less than the second. What is the second number?
c=5a-20
6a+5a-20=112
11a-20+20=112+20
11a/11=132/11
a=12

The record of an athlete shows that she scores 0.82 of the points she attempts to make. What is the probability that she makes her first point on attempt number 4?
Answer:
The probability is 0.00478224
Step-by-step explanation:
Probability of scoring an attempt is 0.82
Probability of not is 1-0.82 = 0.18
So making the first point in attempt number 4 means that she failed the first three
So we have the probability as;
0.18 * 0.18 * 0.18 * 0.82 = 0.00478224

Kristi gets $10 a week from her parents if she washes the dishes after dinner every night. Kristi has saved up $30 over the last few weeks from her allowance. She wants to continue saving her allowance until she has enough money to buy the $70 bike she saw at the store last week. Assuming Kristi receives her allowance every week, write an equation that shows how many more weeks Kristi has to save her allowance to buy the bike, where w is the number of weeks.
Answer:
4
Step-by-step explanation:
70=10w+30
70 is the total she needs for the bike, 10 is the total amount of dollars she gets per week, w is the total numbers of weeks she worked, and 30 is the total amount of money she already has.

A recursive formula for the sequence 18, 9, 4.5, ... is
Answer:
Hope this image helps answer your question
and mark brainliest please.
The recursive formula is aₙ= aₙ₋₁ /2 for n > 1.
What is Recursive Formula?A recursive formula is a formula used to describe a sequence of numbers, where each term in the sequence is defined in terms of the preceding term(s). In other words, it is a formula that uses one or more of the previous terms in the sequence to generate the next term.
The recursive formula for a sequence gives a way to find any term of the sequence using the previous term(s).
To find the recursive formula for the sequence 18, 9, 4.5, ..., we need to look at how each term is related to the previous term.
We can see that each term is half of the previous term, so the recursive formula is:
a₁ = 18 (the first term is given)
aₙ= aₙ₋₁ /2 for n > 1
This means that to find the nth term of the sequence, we divide the (n-1)th term by 2. For example:
a_2 = a_1/2 = 18/2 = 9
a_3 = a_2/2 = 9/2 = 4.5
a_4 = a_3/2 = 4.5/2 = 2.25
and so on.
