(24 points) Need some help please !

Answer:

15/8

Step-by-step explanation:

Literally find the common denomiator. That's the first step for any of these computational fraction problems.

Here are the following denomiators: 4,8,3,6. You notice that 24 is a multiple of all the numbers. Thus, our common denomiator is 24. Next we change each fraction based on our new denomiator

3/4 = 18/24

5/8 = 15/24

2/3 = 16/24

1/6 = 4/24

Now we do basic computation

18/24 + 15/24 + 16/24 - 4/24 = 45/24 = 15/8

Answer:

Step-by-step explanation:

Plug the point (-1,20) into the equation.

20 = a|-1|+7

13 = a|-1|

13 = a ⋅ 1

a= 13

:::::

(1,20) is another point on the graph.

Answer:

a = 22

Step-by-step explanation:

To find a, divide each side by 1/2, or multiply by the reciprocal:

1/2a = 11

a = 22

So, a = 22

Answer:

a = 22

because when isolate a you move 1/2 over with 11, and when you do that insted of multyplying 1/2 times a you divide 1/2 by 11

Answer:

c and d

Step-by-step explanation:

Answer:

4.5%

Step-by-step explanation:

We know she made 21/22. That means she miss 1 so subtract 21 from 22. We get 1. then divide 22 by 1. So the equation is

[tex] \frac{1}{22} [/tex]

which is about 0.454. Then multiply by 100 to get the percent which is 4.54. Round to nearest tenth and we get 4.5%

Answer:4/12

Step-by-step explanation:

Answer:

Set 1    Yes

Set 2    No

Set 3 and Set 4   ???

Step-by-step explanation:

Use the converse of the Pythagorean theorem.   Square the lengths and see if 2 results add up to the third result.

So, Set 1

[tex]10^{2} = 100 \\26^{2} = 676\\24^{2} = 576[/tex]       100 + 576 = 676  Therefore we have a right triangle

Set 2

[tex]4^{2} = 16\\2^{2} = 4\\6^{2} = 36[/tex]

16 + 4 ≠  36   Therefore we do NOT have a right triangle

I will let you do Set 3 and Set 4.  OK?

set 1 is the answer ............................................................

Answer:Median = Mid value of Set of observation

If number of observation is odd, suppose n

Median =  th term

If number of observation is even , then

Median = Mean of two middle observation i.e

Data set : 17, 20, 30, 28, 18

Data arranged in ascending order: 17,18,20,28,30

Let one data =x

Number of observation is even.

Given, Median = 24

As , when number of observation is even , median is mean of two mid values.

Median=→→→ getting the median.

So, x must be greater than 30.

The correct option satisfying the above condition is Option (D) 34.

Step-by-step explanation:

Answer:

A. The missing number is 11

Step-by-step explanation:

The highest number in the set is 30 and the lowest is 12, this makes the range 18.

30 is supposted to be there to make the range what the problem says it is: 12.

20 and 25 could be there because no matter what, as long as 30 is the greatest number, 20 and 25 don't effect the range AT ALL.

If 11 was in the number sequence, the lowest number would be 11, making the range 19, (30-11=19) which is not what the teacher is saying the range is.

So in short, A. The missing number is 11 is the correct answer.

Step-by-step explanation:

exponents first

2*2*2

10+8*2

10+16

26

Answer: 26

Step-by-step explanation:

First you do 2 to the power of three and that is 8.

Then 8 * 2 = 16

Finally 16 + 10 = 26

Answer:

5

Step-by-step explanation:

First divide by 10 on both sides:

-20/-4

-4 divided by -20 is 5

Thus 5 is the answer

Answer:

Bill by $85

Step-by-step explanation:

Bill :  Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. The total initial amount of the money given  is then subtracted from the resulting value.

Compounded annually for 6 years at 9 % interest Bill would have $8385.50.

Joe : Simple interest at 11% a year The formula we'll use for this is the simple interest formula.

P is the principal amount, $5000.00.

r is the interest rate, 11% per year, or in decimal form, 11/100=0.11.

t is the time involved, 6year(s) time periods.

So, t is 6year time periods.

To find the simple interest, we multiply 5000 × 11 × 6  = 3300

Usually now, the interest is added onto the principal to figure some new amount after 6 year(s),

or 5000.00 + 3300.00 = 8300.00

As you can see Bill has more by $85.

Step-by-step explanation:

Given

[tex]Sum = 3\frac{1}{3}[/tex]

Required

Determine the fraction used

Since options, were not given. I'll answer on a general term

Assume, Austin used 2 fractions (a and b)

Such that:

[tex]a + b = 3\frac{1}{3}[/tex]

Also:

Assume that:

[tex]a = \frac{2}{3}[/tex]

Note that this could be any fraction, but I chose to use 2/

Make b the subject in [tex]a + b = 3\frac{1}{3}[/tex]

[tex]b = 3\frac{1}{3} - a[/tex]

[tex]b = 3\frac{1}{3} - \frac{2}{3}[/tex]

[tex]b = \frac{10}{3} - \frac{2}{3}[/tex]

Take LCM

[tex]b = \frac{10-2}{3}[/tex]

[tex]b = \frac{8}{3}[/tex]

[tex]b = 2\frac{2}{3}[/tex]

So, the fractions are:

[tex]a = \frac{2}{3}[/tex] and [tex]b = 2\frac{2}{3}[/tex]
