Erika read 90 pages in 2 and half hours. At the same time, how many hours would it take her to read 225 pages?
Answer:
6.25 hours
Step-by-step explanation:
pages per hour
pages/hour
90/2.5 = 36
36 pages per hour
225 / 36 = 6.25 hours
Answer:
6.25 hours
Step-by-step explanation:
2 and half hours = 2.5 hours
Proportions:
90 pages ⇔ 2.5 hours
225 pages ⇔ E hours
E = 225*2.5/90
E = 6.25 hours
6.25 hours = 6 and 1 quarter hours

A company is designing a new cylindrical water
bottle. The volume of the bottle will be 134 cm3.
The height of the water bottle is 7.1 cm. What is
the radius of the water bottle? Use 3.14 for i.
The radius of the water bottle is about
cm. (Round to the nearest tenth as needed.)
Answer:
Cylinder Volume = PI * radius^2 * height
Radius = Square Root [Volume / (PI * height)]
Radius = Square Root [ 134 / (3.14 * 7.1)]
Radius = 2.45103
Radius = 2.45

Solve 4x- c = k for x.
A. x = k-c/4
B. x = 4(k-c)
C. x- k+c/4
D. x = 4 (k+c)
Answer:
A
Step-by-step explanation:
You would first add c to the side that k is on and then divide k+c by 4 because it is 4x which means they are being multiplied together so you have to divide to get them apart.
Answer:
C. x= k+c/4Step-by-step explanation:
[tex]4x- c = k[/tex]
Move -c to the right side and change its sign
[tex]4x = k+c\\[/tex]
Divide both sides of the equation by 4
[tex]\frac{4x }{4} = \frac{k+c}{4}\\ \\x = \frac{k+c }{4}[/tex]

What is an algebraic expression for 32 more than a number n
Answer:
n + 32
Step-by-step explanation:
More than indicates you are adding. 32 more than n is shown by the expression n + 32.
The algebraic expression for 32 more than a number n is 32 + n where n is the real number.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
32 more than a number n
Here n is the real number.
As we know,
The linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.
If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.
The expression can be written mathematically,
32 more than a number n = 32 + n
Thus, the algebraic expression for 32 more than a number n is 32 + n where n is the real number.

what is the distance between the points (4,-2) and ( -1, 10)
Answer:
The answer is 13 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question
The points are (4,-2) and ( -1, 10)
The distance between them is
[tex]d = \sqrt{ ({4 + 1})^{2} + ({ - 2 - 10})^{2} } \\ = \sqrt{ {5}^{2} + ({ - 12})^{2} } \\ = \sqrt{25 + 144} \\ = \sqrt{169} [/tex]

Hey, there!!
Let's simply work with it,
60° + 2x° + (2x+12)° = 180° { being a linear pair}.
or, 72° + 4x = 180°
4x = 180° - 70°
[tex]x = \frac{108}{4} [/tex]
Therefore, the value of x is 27°.
Now,
2x° = (2×27)°= 54°
(2x+12)° = 2×27°+12°= 66°.
(x+2)= 27+ 2= 29°
Now, The left angle is 27°.
Therefore, The answer is option A.

An Internet service provider offers a plan that allows a subscriber to download 2 GB or less of content per month. Define a variable for the amount downloaded. Identify the inequality and the graph that represents the content that can be downloaded.
Answer: Choice C
[tex]0 \le d \le 2[/tex]
Graph with filled in circles at d = 0 and d = 2, shading in between
==========================================
Explanation:
d = amount downloaded in gigabytes
The smallest amount is d = 0. We cannot download a negative amount of data, so this is why d = 0 is the smallest.
The largest amount allowed is d = 2. This is the cap that the ISP has set up.
So basically d can be anything between d = 0 and d = 2, including both endpoints. This means [tex]0 \le d \le 2[/tex]
We use filled in circles for both endpoints to show to the reader "include these endpoints". Shading is done in between to show the entire solution set of possible d values. For instance d = 1 is in that region so it is possible to have this solution. Something like d = 4 is outside the region and not possible.

Which angles are linear pairs? Check all that apply.
Answer: A & C & D
Step-by-step explanation:
The Angles which are in linear pairs are,
∠SRT and ∠TRV,
∠VRW and ∠WRS,
∠VRU and ∠URS.
What are linear angles?When two lines meet at a single point, they form a linear pair of angles. After the intersection of the two lines, the angles are said to be linear if they are adjacent to one another. A linear pair's angles always add up to 180 degrees. Additional angles are another name for these angles. The angles with a common vertex are called the adjacent angles.
Given the figure and finding linear pair of angles,
The property of linear pair of angles says that the sum of two angles is 180⁰.
A: ∠SRT + ∠TRV = 180⁰
pair is linear
B: ∠SRT + ∠TRU > 180⁰
pair is nonlinear
C: ∠VRW + ∠WRS = 180⁰
pair is linear
D: ∠VRW + ∠URS = 180⁰
par is linear
E: ∠URW + ∠WRS < 180⁰
pair is nonlinear
Hence the linear pairs are (∠SRT and ∠TRV), (∠VRW and ∠WRS), and (∠VRW and ∠URS).

What is greater 1 4/6 or 1 14/21
They’re the same.
Give them common denominators by looking at their least common multiples. 6 and 21 are the denominators and they have to be the same to compare. Their least common multiple is 42.
So 1 4/6 will turn into 1 28/42. I know this because their least common multiple is 42. So I multiplied the 6 by 7 to get 42 as the denominator and you must also multiply the numerator by 6.
1 14/21 will need to be multiplied by 2 to get a denominator of 42. It will turn into 1 28/42. Both simplify down to 1 2/3.
Answer:
The are the same.
Step-by-step explanation:
Because both begin with a 1, ignore that for now.
You have 4/6 and 14/21. Do your best to reduce each. Think about a number that can go into each.
Start with 4/6. They are both even numbers, so 2. 4/2 = 2 and 6/2 = 3
so 4/6 can be reduced to 2/3.
14/21 is trickier, one is odd and the other is even, so no even number will work. 3 can't go in to 14, or 5, but 7 can, and cool! 7 can go in to 21 as well!
14/7 = 2 21/7 = 3 so 14/21 can be reduced to 2/3!
You can also use a common denominator, but you need a calculator for this problem. To solve that way you would take 4/6 and multiply by 21/21 and you would multiply 14/21 by 6/6, this way you'll end up with 126 on the bottom, and you'll see you get 84 on the top.
[tex]\frac{4}{6} * \frac{21}{21} = \frac{84}{124}[/tex]
[tex]\frac{14}{21} * \frac{6}{6} = \frac{84}{124}[/tex]
This is much harder without a calculator. Always try and reduce first, because if you end up having to find a common denominator, it will be smaller and more manageable.
