Answer:
150
Step-by-step explanation:
The ratio is 3:5, so you can make this equation:
[tex]3x+5x=240[/tex], because for any integer x, the ratio will stay the same.
solve that:
[tex]3x+5x=240\\8x=240\\x=30[/tex]
We're not down yet!
we need to find 5x, not x.
[tex]5*30=150[/tex]
There are 150 non-fiction books in the library.
check!
150+90=240
The are 150 non-fiction books are in the library.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
The ratio of fiction to non-fiction books at school library is 3 to 5.
Total books = 240
So, the number of non fiction books
= 240 x 5/8
= 30 x5
= 150
Hence, there are 150 non fiction book.

What is the equation of the line that passes through the point (2,0) and has a slope of 5/2 ?
Answer:
y = [tex]\frac{5}{2}[/tex] x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{5}{2}[/tex] , thus
y = [tex]\frac{5}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, 0) into the partial equation
0 = 5 + c ⇒ c = 0 - 5
y = [tex]\frac{5}{2}[/tex] x - 5 ← equation of line
The equation of the line is the way of represent the line by the given point in the coordinate plane and the its slope.. Thus the equation of the line with point (2,0) and slope 5/2 is,
[tex]y=\dfrac{5}{2} x-2[/tex]
Given information;
The point of the line through which the line passes are (2,0).
The slope of the line is 5/2.
Equation of the lineThe equation of the line is the way of represent the line by the given point in the coordinate plane and the its slope.
The standard form of the equation of the line for point and slope can be given as,
[tex](y-y_1)=m(x-x_1)[/tex]
Put the values,
[tex](y-0)=\dfrac{5}{2} (x-2)[/tex]
Solve it further;
[tex]y=\dfrac{5}{2} x-2[/tex]

PLEASE HELP, #30 and #40 !! DUE SOON
Answer:
38. x = 60
40. x = 10
Step-by-step explanation:
38.
The segment labeled 30 connects the midpoints of two sides of a triangle, so it is parallel and half the length of the third side.
x = 2 * 30 = 60
40.
Look at the big outer triangle.
Its left side has length x. It is made up of two segments that are congruent.
The right side of the big triangle is made up of two segments that are congruent and are also congruent to the segments of the left side. That makes the left and right sides of the big triangle congruent. This is an isosceles triangle, so its base angles are congruent. The left base angle measures 60, so the right base angle also measures 60. That means the top angle also measures 60. This triangle is isosceles and equilateral.
Since the segment measuring 5 has endpoints that are midpoints of two sides of a triangle, it is parallel to the third side and half its length.
The bottom side of the triangle measures 2 * 5 = 10. Since the triangle is equilateral, then x = 10.

Someone plz help. I added a screenshot shot below
Answer:
Juan's Plan
y = .25x+12.95
where y is cost and x is minutes
Tiffany's Plan
y = .15x+14.95
where y is cost and x is minutes
...
Set the cost equal and find where x is the same for both.
.25x+12.95 = .15x+14.95
Group x variables to one side of the equation
.25x + 12.95 - 12.95 - .15x = .15x - .15x + 14.95 - 12.95
.25x - .15x = 14.95 - 12.95
.1x = 2
x=20 minutes

Mary-Ann has $28, which is 2 1 3 as much money as Lola has. How much money does Lola have? find the number
Answer:
Lola has $12
Step-by-step explanation:
To find how much money Lola has, we need to divide $28 by 2 1/3:
28 ÷ 2[tex]\frac{1}{3}[/tex] = [tex]\frac{28}{1}[/tex] × [tex]\frac{3}{7}[/tex] = [tex]\frac{12}{1}[/tex] = 12
Hope this helps! :)
Answer:
$12
Step-by-step explanation:
Lola has x.
Mary-Ann has 2 1/3 times what Lola has. Mary-Ann has $28
2 1/3 * x = 28
Change 2 1/3 into a fraction.
(7/3)x = 28
Multiply both sides by the reciprocal of 7/3 which is 3/7.
(3/7) * (7/3)x = (3/7) * 28
x = 12
Answer: Lola has $12.
Which point lies on the graph of the finite sequence shown? 5,-1,6, 0, 7, 1,8 O (-1,2) (0,5) (5, 1) (6, 1)
Answer: (6,1)
Step-by-step explanation:
A point which lies on the graph of the finite sequence is,
⇒ (6, 1)
Given that;
A sequence is,
⇒ 5, -1, 6, 0, 7, 1, 8
Now, You have to look at the first coordinate (x -Axis) then go over that many times in the sequence and if that number is matched with the y-axis, then you got it.
Hence, Look at your numbers then go to (6, 1) go over 6 and if you land on 1 then that's the answer.
Thus, A point which lies on the graph of the finite sequence is,
⇒ (6, 1)

24. Seven tenths of a number plus 14 is less than forty-nine.
Answer:
50. ☺️☺️
Step-by-step explanation:
I'm going to assume you need this inequality solved.
First, write it as numbers, not words.
7/10n + 14 < 49
where "n" is the unknown number.
Second, if I were you, I'd change that fraction into a decimal, as it'll make life easier later on.
7/10 = 0.7
Now, solve it like you would any other equation.
0.7n + 14 < 49
0.7n +14 - 14 < 49 - 14
0.7n < 35
0.7n ÷ 0.7 < 35 ÷ 0.7
n < 50
The answer is n < 50
Answer: 50
Step-by-step explanation:
49 - 14 = 35
35/7 = 5
10 x 5 = 50
Since, 35 is Seven tenths of a number, One tenth is 5 and there are ten tenths, One tenth which is 5 times ten since there are ten tenths equals to 50 (5 x 10 = 50).
a team of divers assembles at an elevation of -10 ft relative to the surface of the water. Then the team dives at a rate of the water. Then the team dives at a rate of -50ft/min. Write a rule that represents the teams depth d as a function of time t. What is the team's depth after 3 minutes?
Answer: The team will be 160 feet below sea level after 3 minutes.
Step-by-step explanation:
If the team is at -10 ft relative to sea level then it means that they are 10 feet below sea level, and if they also going -50 ft per minute, it also means that they are still going below sea level.
The rule will be, d= -50t -10
If t is the time, input 3 minutes into the equation for t and solve for d to find their depth.
d= -50(3) - 10
d= -150 - 10
d= -160
