If a bat and ball costs $1:10
And the bat costs $1 more than the ball
How much does the ball cost?

Answers

x = bat, y = ball

x + y = 1.10
x = y + 1

y + 1 + y = 1.10
2y + 1 = 1.10
2y = 1.10 - 1
2y = 0.10
y = 0.10/2
y = 0.05 <=== the ball

x = y + 1
x = 0.05 + 1
x = 1.05 <== the bat

Rory is staying in a cabin on a hill 300 feet above sea level. She walks down the hill to the water’s edge. The equation of her average change in elevation over time is e = 300 – 10t, where t is the time in minutes since she left the cabin, and e is her elevation with regard to sea level. Which values are viable points, and what are their values in the table relating t and e?

Answers

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)

125 students have volunteered to be on the prom committee. 2 of those students will be randomly chosen to win free tickets to the prom. How many different ways can the winners be chosen?

Answers

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.

Which simplified fraction is equal to 0.17 (7 repeating)

Answers

So here, I would first multiply 0.17777.... (Assume that that's x) by 10, then you get

10x = 1.777777...

And then subtract x from 10x and then you get 1.6.

So that means that 

10x - x = 9x

and 1.7777... - 0.17777... = 1.6

So now to solve for x, divide both sides by 9

To get 1.6/9 = x

Or 16/90 = x

Or 8/45 = x

(That explanation made no sense)

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]

Karoline needs to jog 30.5 miles over the next 7 days to train for a race. She plans to jog 4.25 miles each day. Use the drop-down menus to complete the statements about her race training.Karoline will jog a total of ______ miles over the next 7 days. Therefore, she will jog______ miles than needed.

Answers

If she plans to jog 4.25 miles each day then 4.25 * 7 would equal 29.75. This is the first answer.
In order to get the second answer, we need to subtract 30.5 (What she needs to jog) over 29.75 (how much she is planned to job over the next 7 days). So 30.5 - 29.75 = 0.75

Problem:

Solve:
5z+7=32

Please SHOW ALL YOUR WORK! (P.S. please show your work clearly, because I will need it for other problems! Thanks!)

Answers

5z+7=32
5z+7-7=32-7
5z/5=25/5
z=5
5z + 7 = 32

1) You have to try to get z by itself, so that means isolating 7 and 5.

5z + 7 = 32
5z - 7   -  7
----------------
5z       = 25

2) Whatever you do to one side, you do to the other. So you subtracted 7 to 7 to isolate 7, and you would subtract 7 to 32 as well. And that will leave you with  5z = 25.

3) Whenever there are a number and a variable next to it, it symbolizes multiplication. (5 x z = 5z) So in order to isolate 5z without taking away your variable, you would have to divide 5 from 5, and also 25.

5z          = 25
__            ___
5                 5
____________
z            =  5

____________________________________________________________
So, the steps are to write the equation out.
Combine any like terms, if there is any. (Ex.  5x + 3 + 52x + 39 {you can combine 5x and 52x because they are like terms, meaning they are alike. Other words are simplifying. (57x) :)}[and you can combine 3 and 39 since they are alike too. (42)])
Then, you add/subtract ON BOTH SIDES!
And after that, you finish it off by multiplying/dividing ON BOTH SIDES.

And how you know if you subtract or add is that if it is positive or negative.
Ex. +5 ( you would subtract in order to get it to zero. So -5)
Ex. -5 ( you would add in order to get is to zero. so +5)

And how you know it's multiplication or division.
Ex. 5x (5 * x = 5x, so you would divide by 5 to get zero, and divide 5 ON BOTH SIDES)
Ex.  \frac{x}{5} [/tex] ( you would have to multiply 5 from top and bottom and ON BOTH SIDES)

The National Safe Kids Campaign and Bell Sports sponsored a study that surveyed 8,159 children ages 5 to 14 who were riding bicycles. Approximately 2/5 of the children were wearing helmets, and of those, only 13/20 were wearing the helmets correctly. About how many of the children were wearing helmets correctly?

Answers

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.

-√17 belongs in only one number set: irrational.
Final answer:

The number -√17 is an irrational number and is part of the set of real numbers.

Explanation:

The number -√17 belongs to the set of real numbers. However, because this number is the square root of a positive number (17) and is multiplied by negative sign, it is not a rational number, but rather an irrational number.

It is part of the real numbers because the set of real numbers includes all numbers that can be plotted on a number line, including integers, rational numbers (numbers that can be expressed as a quotient of two integers), and irrational numbers (numbers that cannot be expressed as a quotient of two integers).

It is specifically an irrational number because the square root of 17 is a non-repeating, non-terminating decimal, and when we multiply this by a negative sign, the numerical value itself does not change, only its direction on the number line.
