What is the ratio of fiction books to nonfiction books on the shelf?
5:4
5:1
4:1
I don't know.
Answer:4:1 just taking to test as soon as you
Step-by-step explanation:
The ratio of fiction books to nonfiction books on the shelf is, 4
What is the ratio?A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.
Given that,
Ellie has 20 books on her shelf
Four of these books are nonfiction
The rest are fiction
The ratio of fiction books to nonfiction books on the shelf = ?
The number of fiction books = ?
The number of fiction books = 20 - 4
= 16
Ratio = fiction/nonfiction
= 16/4
= 4
Hence, the ratio is 4

-60°
O 1287 yd?
2567 yd?
O (64/3) + yd
O (128/2) + yd?
Answer:
A
Step-by-step explanation:
The lateral surface area is given by pi*r*l, we can use trigonometry to find l. 8*sqrt(3)/l=sin(60), l=16 and r is given by tan(60)=8*sqrt(3)/r, r=8. The lateral surface area is 16*8*pi=128*pi

a. A 6 foot high fence casts a 7 foot shadow.
Standing beside the fence is a tree that casts a
31.5 foot shadow. How tall is the tree?
Answer:
height of tree is 27 ft
Step-by-step explanation:
The corresponding parts of the problem are in proportion
let h be the height of the tree , then
[tex]\frac{6}{h}[/tex] = [tex]\frac{7}{31.5}[/tex] ( cross- multiply )
7h = 189 ( divide both sides by 7 )
h = 27
Height of tree is 27 feet

Answer:
y= 0.8
Step-by-step explanation
4(3−y) = 6−2(1−3y)
12−4y = 6−2(1−3y)
12−4y = 6−2+6y
12−4y = 4+6y

Ratio: the ratio of men to women working for a company is 4 to 3. If there are 196 employees in total, how many are women?
Answer:
84 women
Step-by-step explanation:
Using Algebra, we can apply the ratio of men and women, 4 and 3, in a format that can be used in an equation.
4x = men and the unknown variable that will solve the amount of men
3x = women and the unknown variable that will solve the amount of women
Now, we will use the other provided piece which is the total amount of employees, and we will put together an equation!
4x + 3x = 196
We will use this equation to solve for X by the process of addition and division.
4x + 3x = 196
7x = 196
196 ÷ 7 = 28
x = 28
Now we will use this variable and apply it for x to find the number of women.
3 x 28 = 84 women!
Checking the answer:
4 x 28 = 112 men
84 + 112 = 196
Therefore, this answer checks out.
89-x=213 what's the answer?
Answer:
x = -124
Step-by-step explanation:
89-x=213
Subtract 89 from each side
89-x -89=213-89
-x = 124
Multiply each side by -1
x = -124
Step-by-step explanation:
89-x=213
89-213=x
x= -124

convert into like fraction and arrange in ascending order
a)7/8 and 9/10
b) 1/2, 3/4,6/8
Answer:
a) 35/40, 36/40
b) 4/8, 6/8, 6/8
Step-by-step explanation:
In order to convert into like fractions, we must find a common denominator for both.
This just means finding the LCM of the existing denominators.
To find the LCM, list the prime factorization of each number, and multiply each factor together the maximum amount of times it appears in one factor.
Then figure out what you need to multiply the existing denominator by to get the common denominator, and multiply that number to the numerator as well.
Note that multiplying a fraction by x/x won't change the value because x/x is equal to 1.
If this sounds confusing- don't worry- it'll become more clear in the work below.
a) 7/8 and 9/10
Start by finding the LCM of 8 and 10
Prime factorization:
8- 2*2*2
10- 2*5
Multiple: 2*2*2*2*5
However, 2 appears in 10 once and 8 three times.
So we can cross out one "2" since the maximum amount of times it appears is three times, not four.
Hence the LCM is 2*2*2*5=40
40 will be the common denominator.
To get to 40 from 8, you need to multiply it by 5.
So we can do:
7/8*5/5=35/40
Repeat with the second fraction.
To get to 40 from 10, you need to multiply it by 4.
So we can do:
9/10*4/4=36/40
36/40>35/40
Therefore, the ascending order would be
35/40, 36/40 or 7/8, 9/10
b) 1/2, 3/4, 6,8
Start by finding the LCM of 2, 4 and 8.
Prime Factorization:
2: 2
4: 2*2
8: 2*2*2
Since 2 appears a maximum of 3 times in one number the LCM is:
2*2*2=8
So our common denominator will be 8.
To get to 8 from 2, you need to multiply it by 4.
1/2*4/4=4/8
To get to 8 from 4, you need to multiply it by 2.
3/4*2/2=6/8
The last fraction is already good.
6/8
Hence, the ascending order would be:
4/8, 6/8, 6/8 or 1/2, 3/4, 6/8

if A is a subset and equal to B then B'-A' is equal to
Answer:
A-B
Step-by-step explanation:
It doesn't say A=B... But just that A is a subset of B.
Anyways, why not try an example to help reveal the answer.
Let the universe set, U, be U={1,2,3,4,5,6}.
Let B={1,2,3,4} and A={1,3,5}
First choice would become A'={2,4,6}
Second choice would become B'={5,6}
Third choice would become A-B={5}
Fourth choice is just { }
B'-A'={5}
The only choice matching is A-B
