Answer 2
Answer ↓

please view explanation

Calculations ↓

The definition of a fraction is a part of a whole .

If a whole is  divided into equal parts, these equal parts are called fractions.

Fractions are written like this :

\(\boxed{\\\begin{minipage}{4cm}fractions\\$\displaystyle\frac{x\xrightarrow{numerator}}{y\xrightarrow{denominator}} \\ \end{minipage}}\)

 Where

y = the number of total parts

x = the number of parts taken

Now, it doesn't necessarily have to be a pizza or a cake.

Suppose your companion Danette has 32 pencils. Out of them, 8 pencils are red.

What fraction of the pencils is red?

Total number of pencils = 32 (denominator)

Number of red pencils = 8 (numerator)

So the fraction of red pencils is :

\(\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{8}{32} \\ \end{minipage}}\)

If the numerator and denominator are divisible by the same number, then we can reduce the fraction :

\(\boxed{\\\begin{minipage}{4cm}Danette's\:pencils \\ $\displaystyle\frac{1}{4} $\\ \end{minipage}}\)

As a young girl, Tiana enjoyed watching her father make things in his woodworking shop. Now that she's grown up, Tiana builds wooden furniture for a living. Her most popular product is a cedar porch swing. There is a proportional relationship between the time (in days) Tiana spends making porch swings, x, and the number of swings she builds, y.

The equation that models this relationship is y=0.6x.
At this rate, how many swings can Tiana build in 20 days?

Answers

Answer: Tiana can build 12 swings in 20 days

Step-by-step explanation:

We know the equation:

y=0.6x

We can replace the variables.

y=0.6 x 20     (here, im using the x as a multiplication sign)

Now we calculate...

y=12

If it starts at 7 and there are 8 lines going to the number 8, then each line represents 1/8 of the distance between 7 and 8, or 1/8 of a unit. If it stops at the third line, then it has traveled 3/8 of a unit. Therefore, the number it represents is 7 + 3/8, or 7.375.

Answer:

X=54

Step-by-step explanation:

There are multiple steps to find this problem:

So in a triangle, the opposite inverse angles are congruent,

meaning <LQM and <PLQ are congruent so <LQM is also 70 degrees

a triangle = 180 degrees, therefore, triangle QLM can be solved by adding

54 and 70 to find the measure of the 3rd angle

54+70= 124, then 180 (because its the total amount of the triangle) - 124= 56

Then, we know that <QLM and <PQL are congruent angles as they are opposite inverse angles.

So, <PQL also equals 56 degrees

Then to find the 3rd angle of the triangle PLQ you can add 56 and 70 to find the 3rd angle

56+70= 126, Then 180 - 126= 54

So, X=54

Bob's Gift Shop sold 800 cards for Mother's Day. One salesman, Maya, sold 10% of the cards sold for Mother's

Answers

Answer: 80

Step-by-step explanation:

100% - 90% = 10% > 0.1

800 / 0.1 = 80

80 Cards = 10% | 800 x 0.9 = 800, + 80 = 880

The answer is 80 because 10% of 800 is 80

Use a number line to order the numbers from least to greatest.

Answers

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

9/4=2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Jamie buys 3 snacks and 2 bottles of juice. Each snack costs $0.75, and each bottle of juice costs j dollars. The total cost of the snacks and bottles of juice is $6.75. Which of the following equations could be used to find the cost of a bottle of juice, in dollars?

Answers

Answer:

2.25+2j=6.75

That is the answer I got

Answer is 3(.75) + 2j = $6.75 is the equation

Step by step

Since you didn’t give options I will give you my equation.

3 snacks * .75 + 2 juice * x unknown $ = 6.75

3(.75) + 2j = $6.75 is the equation

Solve

2.25 + 2j = 6.75

Subtract 2.25 from both sides to isolate j

2.25 - 2.25 + 2j = 6.75 - 2.25

2j = 4.50

Divide both sides by 2 to solve for j

j = $2.25

A certain star is 4.6 x 10^2 light years from the Earth. One light year is about 5.9 x 10^12 miles. How far from the earth​ (in miles) is the​ star? Has to be answered in scientific notation

Answers

Answer:

2.537 x 10¹⁵ miles

Step-by-step explanation:

We are given the following:

1 light year = 5.9 x 10¹² miles

Distance of the star = 4.3 x 10² light years

To get this we just convert the distance of the star in light years into miles.

We cancel out the light years and then we are left with:

In dealing with scientific notation, when we multiply them we can treat the coefficients and exponents of 10 separately.

Coefficients:

4.3 x 5.9 = 25.37

Exponents of 10:

10² x 10¹² = 10⁽²⁺¹²⁾=10¹⁴

Then we combine them again to form a scientific notation:

25.37 x 10¹⁴

But since the standard in writing a scientific notation, the coefficient needs to be a number from 1-9, we need to move the decimal. When we move the decimal to the right or left, we change the exponent of the power of 10. Since we will move it once to the left, we add 1.

The answer will then be:

2.537 x 10¹⁵ miles
