What is proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
We are Given:
Giovanni can read 210 words per minute and, books contain 540 pages
So, she can read the portion of book
=210/540
= 21/54 per minutes
= 21/54 x 60
= 23.3 pages in one hour
and in 3 hours she can read
= 23.3 x 3
= 70 pages in 3 hours

7. Add or subtract the following polynomials:
a. 5x^2 + 3y^3 - 4x^2 =
b. y^3 + 2y^3 - 8 + 2 =
c. 9 - 3x - 4x + 2x - 12 =
d. -6t + 4t^2 - 6 + 7t - 4t^2 =
Step-by-step explanation:
you will see, this is totally easy. so, once you understand that principle, I am sure you will agree with me that this costs more time putting it in here than just doing it yourself in the future.
you need to consider for addition and subtraction every variable combined with an exponent a different thing, a fruit for example.
you know exactly what to do, when you are being asked to add 3 apples to 2 apples, right ?
or, when are are asked to add 4 apples and 2 pears to 3 apples and 2 pears.
in the first case we simply get 5 (2+3) apples.
in the second case we get 7 (3+4) apples and 4 (2+2) pears.
and nothing else happens here.
we could call x² apples, y² pears, y³ plums, x kiwis, t strawberries, t² raspberries. and the constants could be another fruit or grams of sugar.
now, we simply combine the "fruits" that belong together. there is nothing more to this.
5x² + 3y³ - 4x² = x² - 3y³ (because 5-4 for x²)
y³ + 2y³ - 8 + 2 = 3y³ - 6 (1+2 for y³ and -8+2 constant)
9 - 3x - 4x + 2x - 12 = -5x - 3
-6t + 4t² - 6 + 7t - 4t² = t - 6 (4-4 for t², -6+7 for t)
can some one help please?

Answer:
24x - 16
Step-by-step explanation
What we're doing here is factorisation
To factorise a number, you need to multiply the number outside of the bracket (in this case -4) by both of the inside numbers (-6x and 4).
First,
-4 x -6x
-4 x -6x = 24 , The x also needs to be kept- coming from the -6x, so the answer would be 24x.
You may think that because there are minuses involved, the answer would be -24x but you need to remember the rule that 2 negatives make a positive!
Next,
Multipying the outside number by the second inside again:
-4 x 4 = -16
Alongside the rule that two negatives make a postive, another rule is that one negative and one positive always result in a negative.
Finally,
Connect both of these answers
24x - 16 is the answer!
(The minus/negative symbol in the final answer is because the second multipication turned out negative, if the second number was positive, the answer would be 24x + 16.)

How do you solve 42 = 7/6x
Please help me and explain so I can do this on my own.
Answer:
I'm just trying to help so I don't know if it's correct
42 = 7/6x
you are going to multiply by 6x on both sides then you'll get and cancel the 6x on the right side of the problem
6x × 42 = 7
then you are going to divide by 42 on both sides and cancel the 42 on the left side of the equation, so you'll get 6x = 7/42
next simplify the equation
6x = 1/6
then you will try to get X by itself by dividing by 6 on both sides of the equation
so you'll get X = 1/6 ÷ 6
then you'll flip the second number and you'll get 1/6 then multiply so X will be equal to 1/36
hope you understand
Name the Solid.
What is the VOLUME of the solid?
Round to the nearest tenth if necessary.
Answer:
Rectangular Prism
V= 891 m^2
Step-by-step explanation:
The volume is the base (9x9) times the height (11).
Answer:
The answer should be 891m
Step-by-step explanation:
You multiply the Width, Length, and Height ( 9 x 9 x 11)
which would give you 891m.

A community swimming pool is a rectangular prism that is 30 feet long, 12 feet wide, and 5 feet deep. The wading pool is half as long, half as deep, and the same width as the larger pool.
How many times greater is the volume of the swimming pool than the volume of the wading pool?
Enter your answer as a number, like this: 42
HELLLLPPPP PLEASEEEEEE
Answer:
The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.
Step-by-step explanation:
By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:
Community swimming pool
[tex]V_{c} = l\cdot w\cdot h (1)[/tex]
Wading pool
[tex]V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w (2)[/tex]
Where:
l – Length of the swimming pool, measured in feet.
h – Depth of the swimming pool, measured in feet.
w – Width of the swimming pool, measured in feet.
[tex]V_{c}[/tex] – Volume of the community swimming pool, measured in cubic feet.
[tex]V_{w}[/tex] – Volume of the wading swimming pool, measured in cubic feet.
The ratio of the volume of the community swimming pool to the volume of the wadling pool is:
[tex]\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w} (3)[/tex]
[tex]\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }[/tex]
[tex]\frac{V_{c}}{V_{w}} = 4[/tex]
The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.
