Answer:
Total = 800 books
Step-by-step explanation:
It is given that,
In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.
There if the library has 240 non-fiction books.
Let non fiction books are 3x and fiction books are 7x.
ATQ,
3x=240
x=80
Fiction books = 7x = 7(80) = 560
Total no of books = fiction books + non-fiction books
= 240 + 560
=800
Hence, the total no of books are 800.
3[ 2(10-5) +5(6-5) ] =
The answer is 45 (explained down at the image).
Answer:
45
Step-by-step explanation:
What you wanna do is just simplify the equation as much as possible:
First, the inner parenthesis:
2(10-5)=20-10=10
5(6-5)=30-25=5
And then we have:
3(10+5)=
Just simplify! :)
30+15=45

One of the zookeepers solved to find Bernard's speed
when he is, healthy using the equation:
x - 41.5 = 13.5.
The other Zookeeper said that to solve for Bernard's
speed when he is healthy, they must use the equation:
41.5 + 13.5 = x.
Which zookeeper is correct? Explain.
Answer:
Well both zookeepers are correct but the second zookeepers answer was more accurate.
Step-by-step explanation:
The first zookeeper gave the equation :
[tex]x - 41.5 = 13.5[/tex]
So , In order to find Benards speed which is denoted as x , we would still have to collect like terms to isolate x.
The second zookeeper gave the equation :
[tex]41.5 + 13.5 = x[/tex]
In this equation the zookeeper had already isolated x so, only simple addition was needed to find Bernard's speed.
This equation is easier to solve.

A toy Jeep is 12 1/2 inches long, while an actual jeep measures 18 3/4feet long What is the value of the ratio of the length of the toy jeep to the length of the actual jeep? What does the ratio mean in this situation?
Answer:
1:18
Step-by-step explanation:
Given that,
Length of a toy jeep = 12 1/2 inches = 25/2 inches
Length of an actual jeep = 18 3/4 feet = 75/4 feet
1 foot = 12 inches
75/4 feet = 225 inches
We need to find the ratio of the length of the toy jeep to the length of the actual jeep.
[tex]R=\dfrac{\dfrac{25}{2}}{225}\\\\=\dfrac{1}{18}[/tex]
So, the required ratio is 1:18.

You are painting your room. You mix 1/4 cup of red paint for every 1/2 cup of paint.
A.If you need to make 3 gallons of purple paint, how much red paint will you add?
B. How much blue paint would you need?
C. Make a ratio table to show the amounts of red and blue paint that can be added to make different amounts of purple paint.
Answer:
a- 2/5 + 1/4=.65 mixture of red and blue paint
(2/5) / .65 X 1.625=1 gallon of red paint
(1/4) / .65 X 1.625=5/8 gllaons of blue paint, because
1 + 5/8=1 5/8 gallons of purple paint.
b-1/10 + 2/5 + 1/4=.75 mixture of white, red and blue paint
(1/10) / .75 X 3/8= 1/20 gallons of white paint
(2/5) / .75 X 3/8=1/5 gallons of red paint
(1/4) / .75 X 3/8=1/8 gallons of blue paint, because
1/20 + 1/5 + 1/8=3/8 gallons of lighter purple paint.

PLSSSS SOMEONE HELP MEEE IM STUCK the question is below
Answer:
x=8, y=73/3
Step-by-step explanation:
they ask to solve by substitution so from second equation find y
4x-3y= -41 isolate y
4x+41 = 3y divide both sides by 3
(4x+41)/3= y substitute this y in the first equation
5x+2y = -34
5x+2(4x+41)/3 = -34 distribute and find the common denominator
3*5x+(8x+82)/3 = -34
15x+8x+82=-34*3 cross multiply
23x = -102-82
x=-184/23=8
y=(4*8+41)/3=73/3 is about 24.333..

An unbiased dice with faces marked 1, 2, 3, 4, 5 and 6 is rolled four times. Out of four face values obtained, the probability that the minimum value is not less than 2 and the maximum value is not
greater than 5 is:
a) 1/81 b) 80/81
c) 16/81 d) 65/81
Solution with some explanation
Step-by-step explanation:
Let us intepret this condition in our context:
"...that the minimum value is not less than 2 and the maximum value is not greater than 5"
This means that when we roll the dice, we do not want 1 or 6 to appear. Instead we wish for 2/3/4/5 to appear.
The probability of getting these four sides out of six in a roll is 4/6, or 2/3.
We have to roll this dice 4 times. Hence we raise the probability to a power of 4:
Total probability = (2/3)⁴
= (2)⁴ / (3)⁴
= 16/81. (C)

Answer:
1 =80
2 =100
3 =80
4 =100
6 = 100
7 =80
8 =100
Step-by-step explanation: since 5 and 7 are the same, if u slide the bottom up to the top, 1 and 3 would be the same as 5 and 7
2,4,6,and 8 are 180-80 which equals 100
Answer:
1, 3, 5, 7 = 80°
2, 4, 6, 8 = 100°
Step-by-step explanation:
1, 3, 5, and 7 are congruent to each other
2, 4, 6 and 8 are congruent to each other
1 + 2 + 3 + 4 = 360°
80° + x + 80° + x = 360°
160° + 2x = 360°
2x = 360° - 160°
2x/2 = 200°
x = 100°

Which of the following system of inequalities is the graph below?
HELP ME PLEASE !!!
Answer:
2nd answer choice
Step-by-step explanation:
First, you see which inequalities are represented in the graph. When doing this, I just temporarily the signs to equal signs so just basically ignore the inequalities. Then, when you find the ones with the right numbers, you can worry about the inequalities. Remember that greater than is always the side where the y values increase and less than is always where the numbers on the y axis decrease. Also, pay attention to the equal than sign. If it has a line under the sign, the line has to be solid while if there is no line, then it is dashed. In this problem, The first equation represents the dashed line and the second is the solid line.
Dan invests £8200 into his bank account he receives 2% per year compound interest how much will Dan have after 7 years ?
================================================
Work Shown:
A = P*(1+r/n)^(n*t)
A = 8200*(1+0.02/1)^(1*7)
A = 9419.2224747241
A = 9419.22
Note: I assumed the bank is using annual compounding. The instructions didn't mention it, so that's why I went with n = 1. If your teacher or textbook mention otherwise, say monthly compounding, then you'll change n to n = 12. I would ask for clarification.
