what fraction part remains uncovered if 3 rectangles are covered
use the image below to help you visualize the problem.
I shaded in 3 rectangles and there are 25 rectangles in all. pls help thanks

Answers

Answer 1
At the beginning, you begin with one whole that's been split into 25 pieces, or 25ths. Before you cover any of them up, you still have all 25, so you have 25 25ths, or, as a fraction, [tex] \frac{25}{25} [/tex]. Next, you take away 3 of those 25ths, or [tex] \frac{3}{25} [/tex], which leaves you with [tex] \frac{25-3}{25} [/tex], or [tex] \frac{22}{25} [/tex].

What is 8 ÷ 9 equal I don't get it when my couculator says 0.99999888888888888???!!!

Answers

  "8 ÷ 9 = 8/9" ;  (as a fraction).

Using a calculator:  "8÷9 =                                         "0.88888888888...." ;   or; there may be a value such as:
__________________________________

"0.8888888888888889" ; There may be a "9" at the end;  that is; the calculator may round the value at the end.  
_______________________________________
I suggest recalculating the value on your calcutator.

Please sure to "clear" your calculator.  Usually this can be done by pressing the [AC] button ;  & then.  the [C] or [CE] button.

Then, try:  "8 ÷ 9" again.  You should get value similar to the correct answer; such as: 
______________________
       "0.88888888888" ; 

or:  "0.8888888888888889" .
______________________
Otherwise, there is a possibility that the calculator itself is damaged or broken (e.g. got "stepped on" or "heavy objects" were placed; and the "calculator buttons"/other internal parts of the calculator were damaged and are now malfunctioning).

Isabelle bought 12 bottles of water at $2 each

Answers

Isabelle bought 4 bottles of water.

Here's how to solve for the number of bottles of water Isabelle bought:

Let x be the number of bottles of water Isabelle bought.

The total cost of the water bottles is 2x dollars (2 dollars per bottle * x bottles).

We know the total cost was $21, so we can set up an equation:

Total cost = Cost of water bottles + Cost of pizza

21 = 2x + 13

Now, solve for x:

Subtract 13 from both sides: 21 - 13 = 2x + 13 - 13

Simplify: 8 = 2x

Divide both sides by 2: 8 / 2 = 2x / 2

Get the final answer: x = 4

Therefore, Isabelle bought 4 bottles of water.

Complete question:

Isabelle buys bottles of water at $2 each and a large pizza at $13. The total cost was $21. How many bottles of water did Isabelle buy?

How do you write 13/25 as a percentage

Answers

The fraction 13/25 is equivalent to 52 percent.
To workout this, divide the numerator by the denominator, sum this value to the integer part and multiply the result by 100%, so:
13/25 in percent = 13 ÷ 25 × 100% = 0.52 × 100% =  52%
13/25 as a percentage would just be 52%.

Triangles PQR and MNO are ( here it has a drop down menu I'll include those options below)
Similar or not similar?


Two right triangles, PQR and MNO. For triangle PQR, angle Q is thirty degrees. For triangle MNO, angle N is forty-five degrees.

Answers

Given that the two trianglea are right angles, this means that one of the angles is 90 degrees.

If one on the angles of triangle PQR is 30 degrees, then the third angle will be 60 degres.

Thus, the three angles of triangle PQR are: 90, 30, 60

If one on the angles of triangle MNO is 45 degrees, then the third angle will be 45 degres.

Thus, the three angles of triangle MNO are: 90, 45, 45

For two triangles to be similar, their angles has to equal.

Therefore, triangles PQR and MNO are not similar.
The triangles are not similar. For triangle PQR to be similar to triangle MNO, each angle would have to be congruent. The two triangles only have a 90 degree angle in common. Triangle PQR has 90, 30, and 60 degree angles while triangle MNO has 90, 45, and 45 degree angles.

How do you write 4500 in scientific notation

Answers

45 X 10^3

(forty-five times ten to the third)
First you would want to move a decimal place to the right one position(4,500, 4.500).

Then you are now going to want to count how many places to the right of the decimal ( there are 3 places to the right of the decimal).
 
So building upon what you know, you can now reconstruct the number into scientific notation. Now you are going to the decimal number 4.5 and times with 10 to the third power ( 10 ^3). Now to check your work to see if you did it correctly, you would do 10 to the third power equals 1,000 times 4.5 which equals 4,500 ( 10^3 = 1,000 x 4.5 = 4,500 or 4500.

Consider the given equation:

[tex]a(5-x)=bx-8[/tex]

We have to solve the given equation for the value of 'x', we get

We will use distributive property which states [tex]a(b+c) = ab+ ac[/tex]

[tex](a \times 5)+(a \times -x) = bx-8[/tex]

[tex]5a-ax = bx -8[/tex]

Equating the like terms and the constants, we get

[tex]5a+8= ax+bx[/tex]

Taking 'x' common from the RHS of the equation.

[tex]5a+8 = x(a+b)[/tex]

[tex]x = \frac{5a+8}{a+b}[/tex]

Therefore, the value of 'x' is [tex]x = \frac{5a+8}{a+b}[/tex].

The value of 'x' in equation a(5 - x) = bx - 8 is x=5a+8/(b+a).

Consider the given equation

We have to solve the given equation for the value of 'x', we get

We will use distributive property which states

What is the statement of the distributive property?

a(b+c)=ab+ac

5a-ax=bx-8

Equating the like terms and the constants, we get

5a+8=bx+ax

Taking 'x' common from the RHS of the equation.

5a+8=x(b+a)

x=5a+8/(b+a)

Therefore, the value of 'x' is x=5a+8/(b+a).

Jane says that multiply a decimal by 100 is the same as multiplying the decimal by three factors of 10. Is Jane correct? Explain your answer.

Answers

Jane is incorrect, this is because 3 factors of ten equals 1000(10*10*10=1000) and 100 is not equal to 1000 meaning you are not multiplying by the same number.

Answer:

Jane is incorrect.

Step-by-step explanation:

We have been given a statement. We are asked to determine whether the given statement is true or not.

Jane says that multiply a decimal by 100 is the same as multiplying the decimal by three factors of 10.

[tex]\text{3 factor of 10}=10^3[/tex]

Michael's team won 60% of the 10 football games they played this season they lost the remainder of the games. how many games did Michael team lose?

Answers

60% of 10 is 6. 10 minus 6 is 4. Your answer is 4.
Hope this helped! :)

Final answer:

To find out how many games Michael's team lost, we can calculate the number of games they won and subtract it from the total number of games played.

Explanation:

To find out how many games Michael's team lost, we first need to calculate the number of games they won. We know that they won 60% of the 10 games, so we can calculate this by multiplying 10 by 0.6: 10 x 0.6 = 6. Therefore, Michael's team won 6 games. Since they won the remainder of the games, we can calculate the number of games they lost by subtracting the number of games they won from the total number of games played: 10 - 6 = 4. Therefore, Michael's team lost 4 games.

(02.02 LC) Choose the equation that could be used to find three consecutive integers whose sum is 36. (5 points) n + (n + 2) + (n + 4) = 36 n + (n + 1) + (n + 3) = 36 n + (n + 1) + (n + 2) = 36 n + (n − 1) + (n − 3) = 36

Answers

n + (n + 1) + (n + 2) = 36 Let's first create the equation ourselves and then see if it fits any of the available options. We want 3 consecutive integers that add up to 36. Let's use the value "n" to represent the first number in the sequence. n Now the next number will be n+1 and the third will be n+2. And since we want the sum, we get n + n + 1 + n + 2 = ? And finally, we want the sum to be 36, so our final equation is n + n + 1 + n + 2 = 36 With this equation in mind, let's look at the available choices. n + (n + 2) + (n + 4) = 36 Well, it has the 36 OK, but it has +2 and +4 where we have +1 and +2. So it won't fit and it's wrong. n + (n + 1) + (n + 3) = 36 Closer. Got the 36 and the +1. But it has +3 instead of +2, so not a fit either. n + (n + 1) + (n + 2) = 36 This looks good. Has a couple of extra parenthesis, but they don't affect the final answer and it has the +1, +2 and the 36. This one is correct. n + (n â’ 1) + (n â’ 3) = 36 Hmm. The n - 1 has a possibility. Perhaps they want n to be the middle of the 3 numbers to add. If that's the case, then the other number should be n+1 which it isn't. Maybe they want the n to be the last number. If that's the case, then the third number should be n-2. But that doesn't work either. So this equation won't work. So of the 4 choices, the only answer that works is "n + (n + 1) + (n + 2) = 36"

Write an exponential expression in the form (b)c that reveals the monthly interest rate of Jacki's credit card. Round any decimals to the nearest thousandth.

Answer:

[tex]A=2250(1.014)^{12t}[/tex] is the exponential expression.

Step-by-step explanation:

The expression which represents the balance of credit card, in dollars, after t years is

[tex]A=2250(1+\frac{0.17}{12})^{12t}[/tex]

Where rate of interest is 17% and amount spent is $2250.

Since 17% interest is the annual interest and we have done the expression in the form of monthly compounding.

Dawn is an avid reader and reads 30 pages every 8 days. Part A How many pages per day does Dawn read? Part B At this rate, Dawn takes 28 days to read her favorite novel. How many pages does the novel have?

Answers

Final answer:

Dawn reads 3.75 pages per day. At this rate, a favorite novel that she completes in 28 days contains 105 pages.

Explanation:

This is a problem of rates and proportions.

Part A: To find out how many pages Dawn reads in a day, we divide the total pages she reads in 8 days by the number of days. Going by the data, if she reads 30 pages in 8 days, then, using the proportion, Dawn reads 30/8 = 3.75 pages per day.

Part B: To find out how many pages Dawn's favorite novel has, we multiply the rate (pages/day) by the number of days. So, if she takes 28 days to read the novel at a rate of 3.75 pages per day, then by using the multiplication principle, the novel has 3.75 pages/day * 28 days = 105 pages.
