Answer:

[tex]\frac{8}{45}[/tex]

Step-by-step explanation:

We are given that

[tex]0.1\bar 7[/tex]

We have to find the value in fraction of given rational number

Let x=[tex]0.1\bar 7[/tex]

Multiply on both side by 10 then we get

[tex]10 x=1.77...[/tex]

[tex]10x=1.6+0.1\bar 7[/tex]

Substitute the value then we get

[tex]10x=1.6+x[/tex]

[tex]10x-x=1.6[/tex]

[tex]9x=1.6[/tex]

[tex]x=\frac{1.6}{9}[/tex]

[tex]x=\frac{16}{90}[/tex]

[tex]x=\frac{8}{45}[/tex]

Hence, the fraction =[tex]\frac{8}{45}[/tex]

we know that

The number [tex]9.125*10^{10}[/tex] is equal to

[tex]9.125*10^{10}=9.125*(10,000,000,000)=91,250,000,000[/tex]

therefore

the answer is

The number in standard form is equal to

[tex]91,250,000,000[/tex]

The improper fraction of the given expression is [tex]\frac{44}{9}[/tex].

A fraction with a numerator greater than or equal to the denominator is said to be improper. The denominator is the lower number, and the numerator is the top number. When you have wholeness or more than one whole, you can have improper fractions. Here are a few instances of incorrect fractions:

7/5 18/18 100/13

We can see the number of pieces we have in the numerator and the number of parts we are dividing by in the denominator. In the case of an improper fraction, like the first one mentioned above, there are seven parts, each of which is a fifth of the whole.

The improper fraction of [tex]4 \frac{8}{9}[/tex]  [tex]=[/tex] [tex]\frac{(9*4)+8}{9}[/tex]  

                                               [tex]=[/tex] [tex]\frac{36+8}{9}[/tex]

                                               [tex]=[/tex] [tex]\frac{44}{9}[/tex]

Hence, the improper fraction of the [tex]4 \frac{8}{9}[/tex] is [tex]\frac{44}{9}[/tex] .

To find the volume of a paperweight given its mass of 50g and density of 2.5g/cm³, you can use the formula Volume = Mass/Density. After substituting the given values into the formula the result is 20 cm³.

The question is asking to find the volume of a paperweight given its mass and density. The formula used to find the volume when mass and density are given is: Volume = Mass/Density. Given that your paperweight has a mass of 50g and a density of 2.5g/cm³, you can use this formula to find volume.

First, substitute the values into the formula:

Volume = 50g / 2.5g/cm³

This calculation gives you a volume of 20 cm³. So, your paperweight takes up 20 cubic centimeters of space.

Final answer:

To find the number of children wearing helmets correctly, multiply 2/5 by 8,159 to get the number of children wearing helmets, then multiply that result by 13/20 to get the number of children wearing helmets correctly, which is approximately 2,134.

Explanation:

The student's question involves mathematical computations to determine how many children were wearing helmets correctly out of a surveyed group. The data provided indicates that 2/5 of the 8,159 children were wearing helmets, and out of those, 13/20 were wearing the helmets correctly. To calculate the exact number of children wearing helmets correctly, we should perform the following steps:

Calculate the number of children wearing helmets: (2/5) × 8,159 = 3,263.6, which we can round down to 3,263 children, since we cannot have a fraction of a child.

Calculate the number of children wearing helmets correctly: (13/20) × 3,263 = 2,134.95, which we can round down to 2,134 children wearing helmets correctly.

Therefore, approximately 2,134 children were wearing helmets correctly.

Rory's change in elevation over time is described by the equation e = 300 - 10t. Viable points are (0, 300), (10, 200), (20, 100), and (30, 0) feet, indicating that she reaches sea level after 30 minutes.

Understanding Rory's Change in Elevation:

Rory is walking down a hill from a cabin that is 300 feet above sea level. The equation describing her elevation over time is given by e = 300 - 10t, where e represents elevation regarding sea level, and t is the time in minutes since she started her journey.

Calculating Elevation Points:

To determine the viable points, we'll plug in different values of t into the equation to get corresponding values of e:

When t = 0,
e = 300 - 10(0) = 300 feet

When t = 10,
e = 300 - 10(10) = 200 feet

When t = 20,
e = 300 - 10(20) = 100 feet

When t = 30,
e = 300 - 10(30) = 0 feet

These values suggest that at t = 30 minutes, Rory reaches sea level.

Creating a Table:

The viable points and their corresponding values of e can be summarized in the following table:

(t = 0, e = 300 feet)

(t = 10, e = 200 feet)

(t = 20, e = 100 feet)

(t = 30, e = 0 feet)

Final answer:

There are 7,750 different ways the two winners can be chosen from the 125 students volunteering for the prom committee, calculated using the combination formula C(n, k) = n! / (k!(n-k)!).

Explanation:

To determine how many different ways the two winners can be chosen from the 125 students, we need to use the concept of combinations, because the order in which we choose the winners doesn't matter. The formula for combinations is given by:

C(n, k) = n! / (k!(n-k)!)

where:

n represents the total number of items,

k represents the number of items to choose.

For this situation:

n = 125 (total students),
k = 2 (winners to choose).

Therefore,

C(125, 2) = 125! / (2!(125-2)!)

= 125! / (2! * 123!)

= 125 * 124 / (2 * 1)

= 7750

So, there are 7,750 different ways the winners can be chosen to win free tickets to the prom.

Step-by-step explanation:

To find -115 + (-35), simply add the two numbers as if they were positive, then add a negative sign, resulting in -150. It can be written as a fraction in simplest form as -150/1.

The operation in this question is addition. You are adding two negative numbers.

To add two negative numbers, simply add the numbers as though they were positive, then add a negative sign to the result. So, in this case, you would add 115 and 35 to get 150, then add a negative sign to your answer, resulting in -150.

This can be written as a fraction in simplest form as -150/1. It's also important to note that any number over 1 is simply the number itself, so -150/1 is essentially just -150.
