A fraction is a way to describe a part of a whole. The fraction of an hour for which Ruby studied is (1/2).

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Given that Jamal spent 1 1/2 hours studying for his science test, while Ruby studied for 1/3 the amount of time that Jamal studied. Therefore, we can write,

[tex]\rm \text{Time for which Ruby studied} = 1\dfrac12 \times \dfrac13\\\\\text{Time for which Ruby studied} = \dfrac32 \times \dfrac13 = \dfrac12\ hours[/tex]

Hence, the fraction of an hour for which Ruby studied is (1/2).

Answer:

$ 129.34 will be the total payment made after two months if she made no initial payment

Step-by-step explanation:

annual interest rate = 15.9 %

initial charge = $126

to get the annual interest paid = 15.9% of $126

                                                  = 0.159 * $126 = $20.03

monthly interest paid would be = annual interest  / 12 months

                                                    = 20.03 / 12 = $1.67

hence in 2 months Rita will pay = initial charge + monthly interest * 2

                                                    = $126 + $ 1.67 *2 = $ 126 + $3.34

                                                    = $ 129 .34

Interest rates are always given an annual interest rate.

Answer:

The length of Mai's bike ride was 2.1 times the length of Noah's ride.

Step-by-step explanation:

Mai biked 5 1/4 miles today

So he biked, in miles:

[tex]5 + \frac{1}{4} = \frac{5*4 + 1}{4} = \frac{20+1}{4} = \frac{21}{4}[/tex]

Noah biked 2 1/2 miles.

So, in miles, he biked:

[tex]2 + \frac{1}{2} = \frac{2*2 + 1}{2} = \frac{4+1}{2} = \frac{5}{2}[/tex]

How many times the length of Noah’s bike ride was Mai’s bike ride?

We divide the Mai distance by Noah's distance. In a division of fractions, we multiply the numerator by the inverse of the denominator. So

[tex]\frac{\frac{21}{4}}{\frac{5}{2}} = \frac{21}{4} \times {2}{5} = \frac{21*1}{2*5} = \frac{21}{10} = 2.1[/tex]

The length of Mai's bike ride was 2.1 times the length of Noah's ride.

Step-by-step explanation:

Given:

The scale on a map is 1:25000.

To find:

How many km on the ground is represented by 6cm on the map?

Solution:

Let x be the km on the ground.

We know that,

1 km = 1000 m

1 m = 100 cm

So,

1 km = 100,000 cm

x km = 100,000x cm

The scale on a map is 1:25000. It means the ratio of map and ground is equal to 1:25000.

[tex]\dfrac{1}{25000}=\dfrac{6}{100,000x}[/tex]

[tex]\dfrac{100,000x}{25000}=6[/tex]

[tex]4x=6[/tex]

[tex]x=\dfrac{6}{4}[/tex]

[tex]x=1.5[/tex]

Therefore, 1.5 km on the ground is represented by 6cm on the map.

The percentage of regular grade gasoline sells for between $3.35 and $3.55 per gallon is 64%

The percentage of regular grade gasoline sells for between $3.35 and $3.65 per gallon is 81.5%

The percentage of regular grade gasoline sells for less than $3.55 per gallon is 84%

Given :

Mean retail price is $3.45

Standard deviation is 0.10

Empirical rule states that 99.7% of data is observed in normal distribution that lies within 3 standard deviations.

68% of data lies under 1 standard deviation

95% lies under 2 standard deviations

99.7% lies under 3 standard deviations

there are 3 standard deviations on the left and right of mean . The graph is attached below

Mean is 3.45. standard deviation is 0.1

3.45+0.1=3.55

3.45-0.1=3.35

So 3.35  and 3.55 lies under first standard deviation

The percentage between $3.35 and $3.55 is 68%

3.45 +0.1+0.1=3.65

3.35 lies on 1 standard deviation on left and 2 deviations on the right of mean

So , 34+34+13.5=81.5%

The percentage between $3.35 and $3.65 is 81.5%

For gasoline sells for less than 3.55 , there are 3 standard deviation on the left of mean and 1 standard deviation on the right

0.15+2.35+13.5+34+34=84%

Step-by-step explanation: Part A:

3x−6y=−12;x−2y=−8

Rewrite equations:

x−2y=−8;3x−6y=−12

Step: Solvex−2y=−8for x:

x−2y=−8

x−2y+2y=−8+2y(Add 2y to both sides)

x=2y−8

Step: Substitute2y−8forxin3x−6y=−12:

3x−6y=−12

3(2y−8)−6y=−12

−24=−12(Simplify both sides of the equation)
