i need help with subtracting,multiplying,dividing,and adding fractions.

Adding fractions

To add two fractions, you have to make sure that the numbers in the denominator are the same.

For the fractions

[tex]\frac{1}{2}+\frac{2}{5}[/tex]The denominators are different, you have to look for a common factor between 2 and 5, the quickest way is to multiply them, you know that 10 is both a multiple of 2 and of 5.

Multiply 1/2 by 5 to obtain the equivalent expressed in tenths and multiply 2/5 by 2 to obtain the equivalent fraction in tenths

[tex]\frac{1}{2}\cdot5=\frac{5}{10}[/tex][tex]\frac{2}{5}\cdot2=\frac{4}{10}[/tex]Now that both fractions have the same denominator you can add them

[tex]\frac{5}{10}+\frac{4}{10}=\frac{5+4}{10}=\frac{9}{10}[/tex]Subtracting Fractions

You must apply the same procedure when subtracting two different fractions. First find a common factor so that the denominator is the same for both fractions:

[tex]\frac{1}{2}-\frac{1}{5}[/tex]As before, the common factor is 10, so the equivalent fractions will be:

[tex]\frac{5}{10}-\frac{4}{10}=\frac{5-4}{10}=\frac{1}{10}[/tex]Dividing fractions

To divide two fractions you have to do the following steps.

1- Invert the fraction that corresponds to the denominator of the division, i.e. the one you want to divide for (the second one).

This is called a reciprocal fraction.

2-Multiply the first fraction, the one you want to divide by the reciprocal fraction.

3-If possible, simplify the result.

1-Invert the denominator of the division

[tex]\frac{2}{5}=\frac{5}{2}[/tex]2-Multiply the denominator by the reciprocal fraction

[tex]\frac{1}{2}\cdot\frac{5}{2}=\text{ }\frac{1\cdot5}{2\cdot2}=\frac{5}{4}[/tex]1/2 divided by 2/5 equals 5/4

Sam ran 63,756 feet in 70 minutes. What is Sam's rate in

miles per hour? (There are 5,280 feet in one mile.)

Step 1: What is Sam's rate as stated?

The Sam's rate is 10.35 **miles per hours**.

**What is miles per hour?**

In mathematics,** miles per hour** is the unit for the speed measurement. It is used for the calculation of the speed of the train or people or any another objects. It can be calculated by dividing the distance with time.

According to the question, the given data states that the Sam ran 63,756 feet in 70 minutes.

Distance = 63,756 feet and Time = 70 minutes

And the given conversion is: 5280 feet = 1 miles

Therefore, Sam's rate or speed in **miles per hour** is as written below:

Speed = Distance/Time

Speed = (63,756/70) x (1/5280) x 60 = 10.35 **miles per hours**

Hence, the Sam's rate is 10.35 **miles per hours.**

A microwave is placed on top of two boxes. One box is 3 feet 5 inches tall, the other box is 2 feet 8 inches tall, and the microwave is 3 feet 10 inches tall. How tall are they combined? Write your answer in feet and inches. Use a number less than 12 for inches.

The combined **length** is 9 feet 11 inches

**What is length?**

Distance is measured by **length**. **Length** is a quantity having the dimension distance in the International System of Quantities. Most measuring systems use a base unit for** length** from which all other units are derived. The metre is the basic unit of **length** in the International System of Units (SI). The greatest extended dimension of a stationary item is typically believed to be its **length**. This is not always the case, as it may depend on the location of the item. Height, sometimes known as vertical** length** or vertical extent, and width, breadth, or depth are all words used to describe the **length** of a stationary object. When **length** is the greatest dimension, width or breadth generally relate to a lesser dimension.

Given, **length** of a box = 3 feet 5 inches

**length **of another box = 2 feet 8 inches

**length** of microwave = 3 feet 10 inches

Total **length** = 3 feet 5 inches + 2 feet 8 inches + 3 feet 10 inches

A wireless company offers two cell phone plans. For the month of September Plan A charges $35 plus $0.25 per minute for calls. Plan B charges$20 plus $0.50 per minute for calls. ?

EXPLANATION

Let's see the facts:

Plan A --> $35 + $0.25/minute

Plan B --> $20 + $0.5/minute

Let's call "x" to the number of minutes that a person could talk.

Here we have two equations as follows:

(1) 35 + 0.25x

(2) 20 + 0.5x

Where x represents the number of minutes a person talks on the phone.

We need to equal both equations in order to obtain the same cost.

35 + 0.25x = 20 + 0.5x

Now, we need to solve this equality as shown as follows:

-Subtracting -35 to both sides:

35 + 0.25x -35 = 20 + 0.5x -35

-Adding similar terms:

0.25x = 0.5x - 15

-Subtracting -0.5x to both sides:

0.25x - 0.5x = -15

-Adding similar terms:

-0.25x = -15

-Dividing both sides by -0.25:

x = -15/-0.25

-Simplifying:

x= 60 minutes

**So, when a person talks for ****60 minutes**** the cost of both plans is the same.**

Which of the following ratios does NOT represent a proportional relationship?

**ANSWER**

D 3/4 = 8/6

**EXPLANATION**

For the ratios to be proportional, the fraction on the left hand side must be equivalent to the one on the right hand side.

So, for each of them, we will **check if the values are the same.**

a) 3/4 = 6/8

Simplifying 6/8 by dividing numerator and denominator by 2 yields:

3/4 = 3/4

**The ratio is proportional.**

b) 3/6 = 4/8

Simplifying both sides yields:

1/2 = 1/2

**The ratio is proportional.**

c) 4/3 = 8/6

Simplifying 8/6 by dividing numerator and denominator by 2 yields:

4/3 = 4/3

**The ratio is proportional.**

d) 3/4 = 8/6

Simplifying 8/6 by dividing numerator and denominator by 2 yields:

3/4 = 4/3

Because the two fractions are not equal, **the ratio is not proportional.**

**The answer is D.**

Given data:

Population Mean = 346

Standard Deviation = 72

Expected Value of e(x) = population mean =** 346**

Sample Size = 216

In this case, if many random samples of 216 are taken, then the mean of the sample mean numbers per week is 346. **(Option C)**

To solve for the variance of x or var(x), we follow the formula below:

[tex]var(x)=\frac{\sigma^2}{n}=\frac{(s\tan darddeviation)^2}{\text{sample size}}[/tex]In this case, the given standard deviation is 72 and the sample size is 216. Therefore, we have:

[tex]var(x)=\frac{72^2}{216}=\frac{5184}{216}=24[/tex]One of the properties of the Sampling Distribution of the Mean is that the sampling distribution of the mean is **approximately normally distributed** so long as the sample size is 30 or higher. **Our sample mean here is 346 with a sample standard deviation of √24 or 4.899.**

How likely is it to observe a sample mean number of sags per week that exceeds 390?

For this one, we have this formula to use:

[tex]z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt[]{n}}}[/tex]Our bar "x" is 390. The "myu" symbol is our population mean which is 346. This σ symbol is the population standard deviation 72 and n is our sample size = 216.

[tex]z=\frac{390-346}{\frac{72}{\sqrt[]{216}}}=\frac{44}{2\sqrt[]{6}}=8.98[/tex]Under a normal curve, the areas defined are between z = -3.5 to z = +3.5. Since our z should exceed > 8.98 and thus far greater than +3.5, then we can say that the probability of having a sample mean that exceeds 390 is** zero.**

An archer releases an arrow with an initial velocity of 24 feet per second at a height of 16 feet. The path the arrow takes can be modeled using the function f(x)=−16x2+24x+16, where f(x) represents the height, in feet, of the arrow and x represents the time the arrow travels in seconds. How many seconds until the arrow hits the ground? Round your answer to the nearest hundredth if necessary. Do not include units in your answer.

**Answer:**

18.25

**Step-by-step explanation:**

From the **quadratic equation **given, the** time **it will take till the arrow hits the ground is 22.75 seconds

To determine when the arrow hits the ground, we need to find the value of x when the height, f(x), is equal to 0. In other words, we need to solve the equation:

To solve this **quadratic equation**, we can use the** quadratic formula**:

x = (-b ± √(b² - 4ac)) / (2a),

where a, b, and c are the coefficients of the quadratic equation

In this case, a = -16, b = 24, and c = 16. Substituting these values into the quadratic formula:

x = (-(24) ± √((24)² - 4(-16)(16))) / (2(-16)).

Simplifying further:

x = (-24 ± √(576 + 1024)) / (-32),

x = (-24 ± √(1600)) / (-32),

x = (-24 ± 40) / (-32).

x = -101/4 or x = 101/4

Since x≠ negative;

x = 101/4 = 22.75 seconds

what % less 60 is 51

To find the percent we are looking for we can use the rule of three:

[tex]\begin{gathered} 60\rightarrow100 \\ 51\rightarrow x \end{gathered}[/tex]then:

[tex]\begin{gathered} x=\frac{51\cdot100}{60} \\ x=85 \end{gathered}[/tex]This means that 51 is 85% of 60.

**Therefore 51 is 15% less than 60.**
