Answer:
For 130 non-fiction books, the number of fiction books can be from 270 to 278.
Step-by-step explanation:
Given that, there are 5 non-fiction books for every 9 fiction books.
Observe that, if the number of fiction books is less than 9, than there will be no no-fiction books.
So, there are 5 non-fiction books for every 9 to (9+8) fiction books
So, by elementary method, there will be 5n non-fiction books for every 9n+8 fiction books, where n is a natural number.
Or, if the number of non-fiction books is 5n, then the number of fiction books will be ranging from 9n to (9n+8).
For, 150 non-fiction books, 5n=150 or n=150/5=30.
Hence, the number of fiction books can be from 9n to (9n+8).
=9x30 to (9x30+8)
=270 to 278.
Hence, for 130 non-fiction books, the number of fiction books can be from 270 to 278.
Explain the difference between a two-variable equation graph and a two-variable inequality graph. Give an example of an equation
Answer:
What makes graphing linear inequalities in two variables different from graphing linear equations in two variables?
The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.

Which of the following statements cannot be assumed from the diagram?
Answer:
Option (2)
Step-by-step explanation:
Option (1).
Points A, B and D are collinear.
True. (On plane S)
Option (2).
Points A, B, C and E are coplanar.
False.
(Points A, B and D are on plane S and points C and E are on plane R)
Option (3).
BE intersects line 'n' at point B.
True.
Option (4).
CB ⊥ AD
(CB lies on plane R and AD lies on perpendicular plane S).
Option (5).
Line 'm' ⊥ plane R.
True.
(Line m is on plane S which is perpendicular to plane R).
Option (6).
Plane R intersects plane S at line n.
True.
Plane R and Plane S are perpendicular and the point of intersection is line 'n'.
Therefore, Option (2) is incorrect.
2. Find the equation of a line parallel to y=6x-4 and through point (-2,14)
Answer: y=6x+26
Step-by-step explanation:
To find the equation of a line parallel to the given equation, the slope must stay the same. Parallel lines NEVER touch or cross. Therefore, the slope MUST be the same. All we have to do is plug the given point into the equation to find the y-intercept.
14=6(-2)+b [multiply]
14=-12+b [add both sides by 12]
b=26
Now, we know that the equation of y=6x+26.

This is what came to me when I saw this question, sorry if it’s wrong :((
Answer:
A: 0 B: 20
Step-by-step explanation:
If the zookeepers used 30 fruits on monkey A, they would only have 20 left to use on monkey B. Same for the veggies. If they used all 70 on monkey B, there wouldn't be any left to give to monkey A.

How many miles are equivalent to 800 meters? Round answer to the nearest hundredth.
0 0.50 miles
1.29 miles
2.62 miles
4.97 miles
Answer:
0.50 mi
Step-by-step explanation:
There are about 1600 meters in a mile*, so 800 meters would be ...
(800 m)/(1600 m/mi) = 0.50 mi
__
* The exact conversion is 1 mile = 1609.344 meters

How many seconds are in 5 years?
how do you find a slope from a table??
Answer:
Pick any point that has x and y together.
For example, 3 4
2 7
1 6
Here the two points which you will be picking is either 3 and 4, or 2 and 7 or 1 and 6.
Once you pick, use the formula: rise/run (which means y/x)
Using the same example above, let's just say that you picked 1 and 6. (remember the first column always represents x values whereas the second column always represent y values). You get the slope by 6/1 = 6.
Hope that helped!!

Joshua and his children went into a grocery store and will buy bananas and peaches.
Each banana costs $0.70 and each peach costs $2. Joshua has a total of $25 to spend
on bananas and peaches. Write an inequality that would represent the possible values
for the number of bananas purchased, b, and the number of peaches purchased, p.
Answer:
[tex]0.7b+2p \leq 25[/tex]
Step-by-step explanation:
So, we know that each banana costs $0.70 and each peach costs $2. So, the total when purchasing b bananas and p peaches can be written as the expression:
[tex]0.7b+2p[/tex]
Where b represents the amount of bananas purchases and p represents the amount of peaches purchases.
Joshua has at maximum $25 to spend. The total cannot exceed $25. In other words, the total of the above expression must be less than 25. So, our inequality will be:
[tex]0.7b+2p<25[/tex]
However, it is also possible for Joshua to spend exactly $25. So, we also need an equal sign. Therefore, our final inequality will be:
[tex]0.7b+2p \leq 25[/tex]
In words, this means that the total cost depending on the number of bananas and peaches Joshua buys must be less than or equal to 25.
And we're done!
16x2
16 to the 2nd power
If you are asking 16x2 then it's 32 .-.
16 to the 2nd power is 256
Answer:
32 and 16 to the second power is 256
Step-by-step explanation:
When you multiply a number to any power the power number is how many times you multiply the other number by itself for instance 16 to the second power is 16x16 if it were to the third then it would be 16x16x16

Step-by-step explanation:
3 10 in . = 7 8 mi . what is the unit rate
Answer: (3/10) in = (7/8) mi
1 in = (7/8) mi ÷ (3/10)
= 7/8 * (10/3) = 70/24
1 in = (70/24) mi
It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.

-6(y + 15) = -3y + 6, what is y?
Answer: 28
Step-by-step explanation:
-6 times y and 15= -6y +90
-6y + 90= -3y + 6 ( 90 -6=84)
-6y + 84= -3y ( -3y + 6 = 3y)
84=3y (84 divided by 3=28)
Y=28
