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

Answer:

Step-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]

We have the final answer as

Answer:

[tex]y = \frac{x}{36}[/tex]

Step-by-step explanation:

Given

Length of string = x inches

Required

Determine the length in yards

Represent the equivalent length with y

Such that

[tex]y = x\ inches[/tex]

Divide x by 36 to get equivalent in yards

[tex]y = \frac{1}{36} * x[/tex]

[tex]y = \frac{x}{36}[/tex]

Hence, the equivalent in yards is [tex]\frac{x}{36}[/tex]

The expression should be [tex]x \div 36[/tex]

Here we need to divide x by 36 so that the equivalent in yards could come

[tex]=\frac{1}{36} \times x\\\\ = \frac{x}{36} [/tex]

First you do whats in the parentheses

So it will look like this

14a+16=86 now you want to get 14a by itself so -16 from 86

then you get 14a=70

now divide 14a from 70 and your answer is 5

Answer:

Use the distance formula to determine the distance between two points.

Exact Form:

4 √ 10

The distance between points (-8, 5) and (4, 9) is 4√10.

A coordinate plane is a plane in which a set of two number lines are represented, horizontal line is called x-axis and vertical line is called y-axis.

The given points are,

P(-8, 5) and Q(4, 9)

To find the distance between points P(-8, 5) and Q(4, 9),

Use formula,

The distance between two points A(x₁, y₁) and B(x₂, y₂)

Distance[tex]AB =\sqrt{(x_2-x_1)^2+ (y_2-y_1)^2}[/tex]

Distance between P(-8, 5) and Q(4, 9),

[tex]PQ = \sqrt{(4+8)^2 + (9-5)^2}\\\\PQ = \sqrt{12^2+4^2}\\\\ PQ = \sqrt{144 + 16}\\\\PQ = \sqrt 160\\\\PQ = 4\sqrt10\\[/tex]

The distance between points P(-8, 5) and Q(4, 9) is 4√10.

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

Step-by-step explanation:

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.

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.

Answer:

False.

Step-by-step explanation:

This is false.

When we carry out the operation -7 + 9, this equals 2.

When we carry out the operation -9 + 7, this equals -2.

Therefore, this is false because of the Commutative Property. It states that

a + b = b + a. Therefore, the equation is only true if both a terms would be negative. It can also apply for b terms.

Answer: The equation is false.

Step-by-step explanation:

So we have this equation here:

-7 + 9 = -9 +7

This equation may look like the Commutative Property, but be CAREFUL! It is NOT the Commutative Property because the Commutative Property has the same numbers, not different numbers.

Here is an example of the Commutative Property:

7 - 8 = -8 + 7

5 + 6 = 6 + 5

Did you notice that if there is a negative sign, when it switches (or commutes) the number keeps the negative sign?

Well if this is the case, then let's apply it to this problem.

-7 + 9 = -9 + 7

-7 and 7 are two different numbers, as are -9 and 9

So it is not the same thing as:

-7 + 9 = 9 - 7

Notice that 7 keeps the negative sign.

Even if we solve this problem, it is false.

-7 + 9 = -9 + 7

2 = -2 is not a equality! 2 and -2 are NOT the same.

Therefore, the equation is false!

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.

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.

-3q - 10

Step-by-step explanation:

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.
