Answer:

529.41

Step-by-step explanation:

From the above question, we are to find the Principal

The formula to find the Principal (Initial amount invested) is =

P = A / (1 + rt)

Where

A = Amount paid after t years. = 720

r = rate of interest = 6% = 0.06

t = time in years = 6

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

P = 720 / ( 1 + (0.06 × 6)) = 529.41176470588

Approximately

P = 529.41

Given:

About 3/5th of the registered voters participated in 2016 election.

California has 25 million registered voters.

To find:

The number of registered voters who participated in 2016 election.

Solution:

We have,

Total number of registered voters = 25 million

According to the question,

[tex]\text{Registered voters who participated}=\dfrac{3}{5}\times \text{Total number of registered voters}[/tex]

Now,

[tex]\text{Registered voters who participated}=\dfrac{3}{5}\times 25[/tex]

[tex]\text{Registered voters who participated}=3\times 5[/tex]

[tex]\text{Registered voters who participated}=15[/tex]

Therefore, there are 15 millions of registered voters who participated in 2016 election.

Answer:

C. 1/4

Step-by-step explanation:

Since John has given 2/3 of his pencils to Roy, he has 1/3 of the total left. To find 1/4 of 1/3, multiply the numbers. 1/4(1/3) = 1/12. This means that he gave 1/12 of the beginning total to Maria. 2/3 can also be written as 8/12, and 1 can be written as 12/12. 12/12 - 8/12 = 4/12, and then 4/12 - 1/12 = 3/12. 3/12 can be simplified into 1/4

Answer:

John's remaining pencils in term of p = p/4

Hence, option 'c' is true.

Step-by-step explanation:

Let 'p' be the total number of pencils

Given that John gives 2/3 of his pencils = 2/3 of p

                                                                   = 2/3 × p

                                                                    = 2/3 p

Pencils left:

[tex]p-\frac{2}{3}p[/tex]

Factor out common term p

[tex]p-\frac{2}{3}p=p\left(1-\frac{2}{3}\right)[/tex]

           [tex]=\frac{1}{3}p[/tex]

           [tex]=\frac{p}{3}[/tex]

Pencils John gave to Maria = 1/4 × p/3 = p/12

The remaining Pencils in terms of 'p' = [tex]\frac{p}{3}-\frac{p}{12}[/tex]

                                                              [tex]=\frac{3p}{12}[/tex]

                                                              [tex]=\frac{p}{4}[/tex]

Thus, John's remaining pencils in term of p = p/4

Hence, option 'c' is true.

Multiplying fractions

Ok, here's an example:

5/10 x 3/10

The numerator is the number on top. The denominator is the number on the bottom.

You multiply the numerators together to get 15.

Then, you multiply the denominators together to get 100.

Once you have 15/100, you would simplify it to get 3/20.

Dividing Fractions

Here's an example:

5/10 divided by 3/10

This is a little different.

Remember this: Keep, change, flip or KCF

So, keep the first fraction 5/10.

Flip the division sign into a multiplication sign.

Then, flip the 3/10 into 10/3

Right now we have 5/10 x 10/3

Now, use what you've learned from multiplying fraction and multiply the numerators together, than the denominators together.

So, you get 50/30.

Then you can simplify it into 5/3.

Three dressers are placed side by side. One dresser is 3 feet 9 inches wide, another is 3 feet 3 inches wide, and the third is 5 feet 11 inches wide. How wide are they combined? Write your answer in feet and inches. Use a number less than for inches

Answer:

12 feet 11 inches

Step-by-step explanation:

To solve the above question, we would have to add up all the width of thee dressers together.

Hence:

3 feet 9 inches + 3 feet 3 inches + 5 feet 11 inches

= (3 feet + 3 feet + 5 feet) + (9 inches + 3 inches + 11 inches)

= 11 feet +( 23 inches)

Note that

12 inches = 1 feet

Hence:

11 feet (23 inches/12 inches)

11 feet (1 feet + 11 inches)

= 12 feet 11 inches.

Therefore, the width of the 3 dressers combined = 12 feet 11 inches

Answer:

k = 3.5

Step-by-step explanation:

The equation representing a proportional relationship is

y = kx ← k is the constant of proportion

Divide both sides by x , then

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

Using the point (1, 3.5 ), then

k = [tex]\frac{3.5}{1}[/tex] = 3.5

The constant of proportionality [tex](\(\frac{y}{x}\))[/tex] for the given proportional relationship is 3.5.

To find the constant of proportionality [tex](\(\frac{y}{x}\))[/tex], we can use the two given points (0, 0) and (1, 3.5) on the graph, which represent the proportional relationship between x and y.

The constant of proportionality [tex](\(\frac{y}{x}\))[/tex] is the ratio of y-coordinates to x-coordinates for any pair of corresponding points in a proportional relationship.

Let's calculate it using the points (0, 0) and (1, 3.5):

[tex]\(\frac{y}{x} = \frac{3.5}{1} = 3.5\)[/tex]

So, the constant of proportionality is 3.5.

The container holds 4.5 cups of yogurt

Step-by-step explanation:

Here, given the number of ounces of yogurt in a container, we want to calculate the number of cups the container can hold

Mathematically, we need a conversion factor

1 cup contains 8 ounces

but here

x cups contains 36 ounces

8 * x= 36 * 1

8x = 36

x = 36/8

x = 4.5

Answer:

Step-by-step explanation:

2160 = 2a * 3b * 5

2160/5 =2a*3b

432=6*a*b

432/6 = a*b

72 = a * b

72 = 8 * 9

a=8

b=9

The number 2160 can be expressed as 2a x 3b x 5 , where a = 8 and b = 9

Given data:

To find the values of a and b in the expression 2^a * 3^b * 5,

2160 = 2a * 3b * 5

Divide by 5 on both sides:

2160/5 =2a*3b

432=6*a*b

Divide by 6 on both sides:

432/6 = a*b

72 = a * b

The values of a and b can be determined as:

72 = 8 * 9

a = 8

b = 9

Hence, in the expression 2a x 3b x 5 = 2160, the value of a is 8 and the value of b is 9.

Answer:

6.50

Step-by-step explanation:

To start off, note that 6 1/2 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.

6 = Whole number

1 = Numerator

2 = Denominator

To get 6 1/2 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.

Here are the detailed math steps we use to convert 6 1/2 mixed number to decimal form:

Step 1: Multiply the whole number by the denominator:

6 × 2 = 12

Step 2: Add the product you got in Step 1 to the numerator:

12 + 1 = 13

Step 3: Divide the sum from Step 2 by the denominator:

13 ÷ 2 = 6.5

That's it! The answer to 6 1/2 in decimal form is displayed below:
