A radio station is giving away a $100 bill to every 30th caller and movie tickets to every 10th caller. If there are 120 callers, how many callers will get both the $100 and the movie tickets?

Answers

Answer:

4 callers

Step-by-step explanation:

Because 10 is a factor of 30, we don't have to worry about it. Every 30th caller will get both rewards. 120/30=4 so the answer is 4.

The area of Joe's square yard is 196 square meters. Since his house is on one side of the yard, Joe only needs to fence the other three sides of the yard. How many meters of fencing does Joe need to enclose his yard? (Number answer only, no units.)

Answers

Answer:

Step-by-step explanation:

So are is length times width,

since we are dealing with a square, then the length and the width are congruent

so we can say that, for this case:

a = length * length

hence

196 = length^2

14 = length

and

14 = width

since only 3 sides of this square are needed, one only has to multiply the length by 3

14 * 3

=42

so only 42 meters of fencing are needed

was is 0.788888 8 is the number that is recoring HELP ME

Answers

0.78 can be written as the fraction 71/90 after simplifying by dividing both the numerator and denominator by the greatest common divisor, which is 0.1.

To rewrite the repeating decimal 0.78 as a simplified fraction, we can use the concept of geometric series.

Let x = 0.78

Multiply both sides by 10 to shift the decimal point:

10x = 7.88

Subtract the original equation from the multiplied equation to eliminate the repeating part:

10x - x = 7.88 - 0.78

This simplifies to:

9x = 7.1

Now, divide both sides of the equation by 9 to isolate x:

x = 7.1/9

To express the fraction in simplest form, we can find the greatest common divisor (GCD) of the numerator and denominator, and then divide both by the GCD:

GCD(7.1, 9) = 0.1

Dividing both the numerator and denominator by 0.1 yields:

7.1/9 ÷ 0.1/0.1 = 71/90

Therefore, the repeating decimal 0.78 is equivalent to the simplified fraction 71/90.

a large water bottle holds 32 fluid ounces which is 0.946353 liter. round this decimal to the nearest thousandth. explain how you rounded the decimal

Answers

Answer:

0.946 liter

Step-by-step explanation:

Here, we are told to round 0.946353 to the nearest thousandth.

The nearest thousandth is simply the third value after the decimal point.

Now to successfully round this number, we need to consider the number after this number. If the number is less than 5, then we round it up as zero and add to the thousandth digit.

in the case where the fourth number is higher than or equal to 5, we turn it to 1 and add it to the thousandth number

In the case of this question however, we can see that the number is less than 5, so we can only round to 0 and this does not affect the thousandth digit .

Aleka and Helene both opened savings accounts that earn 2.5% interest a year. Aleka puts $2,500 into her account. Helene put $1,500 into her account and also saves $200 cash a year. x = number of years Aleka: f(x) = 2500(1.025)x Helene: g(x) = 1500(1.025)x + 200x Which function represents the difference, h(x) = f(x) – g(x), between the value of Aleka's and Helene's total savings after x years? h(x) = –1000(1.025)x + 200x h(x) = 1000(1.025)x + 200x h(x) = 1000(1.025)x – 200x h(x) = 4000(1.025)x + 200x

Answers

Given:

Amount in Aleka and Helene accounts represented by the following function:

Aleka: [tex]f(x) = 2500(1.025)^x[/tex]

Helene: [tex]g(x) = 1500(1.025)^x + 200x[/tex]

To find:

The function represents the difference, [tex]h(x) = f(x) -g(x)[/tex], between the value of Aleka's and Helene's total savings after x years.

Solution:

We have,

[tex]f(x) = 2500(1.025)^x[/tex]

[tex]g(x) = 1500(1.025)^x + 200x[/tex]

Now,

[tex]h(x) = f(x)-g(x)[/tex]

[tex]h(x) = 2500(1.025)^x-[1500(1.025)^x + 200x][/tex]

[tex]h(x) = 2500(1.025)^x-1500(1.025)^x - 200x[/tex]

[tex]h(x) = 1000(1.025)^x - 200x[/tex]

Therefore, the correct option is C.

the high school graduating class of 2000 was 260 people. 5 years later it was 320 people. by 2010 the class rose to 400 people. in what 5 year period. did the high school graduating class experience the greatest experience of change

Answers

answer:

the question is confusing but the answer is 2010

step-by-step explanation:

because in the year 2000 it was

260

then increased by

over 5 years making the next class

320

then in 2010 it was

400

and 320 + what is 400?

so the answer is:

2010

In the year 2010 the high school graduating class experience the greatest experience of change.

What is subtraction?

Finding the difference between two numbers is done using the subtraction technique. The size of a group of things decreases if any of the objects are removed.

For instance, at your birthday celebration, you purchased 9 cupcakes, of which your friends consumed 7. There are only 2 cupcakes remaining for you now. Nine minus seven equals two, which may be represented as the subtraction expression 9 - 7 = 2. (9 - 7) = 2 is the result of subtracting 7 from 9.

According to the question, the given values are :

There are 260 people in the graduating class in 2000, then it increased by 60.

5 years later the people class in the class was 320.

Then in the year 2010, it was 400.

So, the difference between 400 and 320 is 80.

Hence, this concludes that the greatest change will occur in 2010.

simplify: 5x-(2x+y)

help

Answers

Answer:

3x-y

Step-by-step explanation:

Answer:

Simplifying

5x(2x + y) = 0

(2x * 5x + y * 5x) = 0

Reorder the terms:

(5xy + 10x2) = 0

Solving

5xy + 10x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '5x'.

5x(y + 2x) = 0

Ignore the factor 5.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve:

Simplifying

x = 0

Solving

x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying

x = 0

Subproblem 2

Set the factor '(y + 2x)' equal to zero and attempt to solve:

Simplifying

y + 2x = 0

Reorder the terms:

2x + y = 0

Solving

2x + y = 0

Move all terms containing x to the left, all other terms to the right.

Add '-1y' to each side of the equation.

2x + y + -1y = 0 + -1y

Combine like terms: y + -1y = 0

2x + 0 = 0 + -1y

2x = 0 + -1y

Remove the zero:

2x = -1y

Divide each side by '2'.

x = -0.5y

Simplifying

x = -0.5y

Solution

x = {0, -0.5y}

Find the value of this triangle!

Answers

From what I understand, we need to find x, y, and z.

We can easily find x by knowing a triangle has 180°.

Add 72+86=158 and then subtract 180-158 which gets you 22.

Now we have x=22°.

To find y, we first must find z. We can find z using the vertical angles theorem. This means x and z and the same, so z=22°.

Now, we can now find y by adding 70 and 22 = 92.

Subtract 180-92=88°.

All values have been found!

x=22°

y=88°

z=22°
