Two communication companies offer calling plans. With company x, it cost 35 cents to connect and then 5 cents for each minute.With company y, it cost 15 cents to connect and the 4 cents for each minute. Write and simplify an expression that represents how much more company x charges than company y, in cent, for n minutes
Answer:
34
Step-by-step explanation:
Subtract and divide
The amount of money company x charges than company y, in cent, for n minutes will be (20 + n) cents.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
With company x, it cost 35 cents to connect and then 5 cents for each minute.
And, With company y, it cost 15 cents to connect and the 4 cents for each minute.
Now,
Since, With company x, it cost 35 cents to connect and then 5 cents for each minute.
Hence, The cost for n minutes with company x is,
⇒ 35 + 5n
And, With company y, it cost 15 cents to connect and the 4 cents for each minute.
Hence, The cost for n minutes with company y is,
⇒ 15 + 4n
Thus, The amount of money company x charges than company y, in cent, for n minutes = 35 + 5n - (15 + 4n)
= 35 + 5n - 15 - 4n
= (20 + n) cents

Thomas has finished 50% of an art project that has taken him a total of 9 hours so far. If he continues to work at the same rate, how many hours will it take for him to complete the entire project?
Answer:
18
Step-by-step explanation:
If he has worked for 9 hours and its 50% done he has to work for 9 more hours to get it finished so he would have worked on it for 18 hours to get it totally finished
Thomas will take a total time of 18 hours to complete the entire project.
What is Percentage?Percentage of a number is the number of parts of that number in a total of 100. Percentage of a number is found by dividing the number with the whole and then multiply with 100.
Thomas has finished 50% of an art project that has taken him a total of 9 hours.
Let W be the work Thomas has to finish.
Quantity of work Thomas finished in 9 hours = 50% of W
= (50/100) × W
= 0.5W
Remaining work to complete = W - 0.5 W = 0.5W
Again he has to complete 0.5W of total work W which will take an additional 9 hours.
So the total time taken = 9 + 9 = 18 hours.
Hence the total time needed for Thomas to complete the work is 18 hours.

Omar's cats claws grow 1/8 in in 1/12 of a year which is the amount of cats claws will grow in one year
Omar's cat's claws will grow 3/2 inch (or 1.5 inches) in one year.
To find the amount by which Omar's cat's claws will grow in one year, we need to multiply the growth rate per 1/12 of a year by the number of 1/12-year intervals in one year.
Given that Omar's cat's claws grow 1/8 inch in 1/12 of a year, we can find the growth in one year as follows:
Growth in one year = (Growth rate per 1/12 of a year) * (Number of 1/12-year intervals in one year)
Growth in one year = (1/8 inch) * (12 intervals)
Growth in one year = 1/8 inch * 12
Growth in one year = 12/8 inch
Now, we can simplify the fraction:
Growth in one year = 3/2 inch
So, Omar's cat's claws will grow 3/2 inch (or 1.5 inches) in one year.

In 2018, researchers examined a random sample of 1455 "disadvantaged" Australian school children (children aged 6 – 15 from rural and outer suburban areas) and found that 4.3% of them were nearsighted. In 2014, the rate of nearsightedness among such children was 3.5%. Is this strong evidence that the parameter has changed since 2018?
Answer:
No, this is not a strong evidence that the parameter has changed since 2018. This is because, there are so many factors that could have led to the fall in percentage of "disadvantaged school students" from the initial 3.5% to 4.3%.
Some of the factors could be reduction in the number of disadvantaged students, sample size considered being considered as well as the geographic location upon which the random sampling was made.

Answer
Step-by-step explanation:
If 25 goes into 100 four times, then multiple 9 x 4 and then make it into a precent. 9 x 4 = 36, would equal .36
Answer:
To turn 9/25 into a decimal, you could turn the denominator to 100. In order to do this, you can multiply both the numerator and denominator by 4. 9/25 x 4/4 = 36/100. 36/100 converted into a decimal is 0.36.

How do i find the values of of both x and y in a quadrilateral?
Answer:
n stands for the number of sides, which is 4.
To find the sum of the angles, subtract 2 from the number of sides and multiply by 180.
Add all the angles together and set that equal to 360 to solve for x.
Plug 32 ° in for x to find the measures of the angles.

-4(c+2d)-2(3c-4d)
Answer:
-10c
Step-by-step explanation:
-4(c+2d)-2(3c-4d) = (-4c-8d) + (-6c+8d)
Multiply (-4) to both terms in the first bracket and multiply (-2) to both terms in the second bracket.
(-4c-8d) + (-6c+8d) = -4c-8d-6c+8d
Evaluate like terms.
-4c-8d-6c+8d = -10c

Answer:
1. 561%
2. 1
3. 7/80
4. 31.25%
5. 6%
Step-by-step explanation:
To start off, lets learn how to convert decimals to percent's.
Converting is actually not too hard. All you need to do is multiply the decimal by 100.
So 5.61 * 100
That would be 561 and then you add a percent sign to the end.
To convert a percent to a decimal is just the opposite of what we just did. Simply divide the percent by 100.
So 100% /100
A number divided by itself is 1
So 100% = 1
To make this problem easier, you can convert the fraction to a decimal.
8 3/4 = 8.75%
Now divide it by 100
8.75/ 100
0.0875
Now just convert it back to a fraction.
0.0875 = 7/80
Convert to a decimal.
5/16 = 0.3125
Multiply by 100
31.25
add percent sign
31.25%
Last one.
Convert to decimal
3/5 = 0.6
Multiply by 100
6%
