Answer:

Answer: Around 1000 students would buy a school lunch.

Step-by-step explanation:

We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.

In total we have 20 + 14 = 34 students, this will be our 100%.

The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.

p1 = (14/34)*100% = 41.18%

And the percentage of students that buy lunch at school can be computed in the same way:

p2= (20/34)*100% = 58.82%

Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.

Then the exact number will be:

N = (58.82%/100%)*1700 = 1000

Around 1000 students would buy a school lunch.

Answer: 70

90+20=110

180-110=70

I hope this is good enough:

Answer:

70

Step-by-step explanation:

Everything needs to add up to 180. So you have 90 and 20 you will add them and you’ll get 110. Since you want to find the missing measurement you will subtract 180-110 and you’ll get 70. The missing angle is 70. To check: 90+20+70=180

Answer:

-9x+5y=-4

Step-by-step explanation:

Answer:

m= 9/5

Step-by-step explanation:

Parallel lines have the same slope.

So if you can find the slope of the given line, you have the slope you want.

Change the line into the form

y=mx + c

The value of m

will be the slope of the line.

9x −4 = 5y ← to make the y term positive

y=9/5x − 4/5

m=9/5

Answer:

To find slop from the given equation,

Slope (m) =

[tex] \frac{ - \: cofficients \: of \: x }{cofficient \: of \: y} [/tex]

So, slope of this equation is - 2

For perpendicular case,

M1 . M2 = - 1

Thus, m2 = 2 ( for this equation)

Similarly,

For parallel case,

M1 = m2

Thus, m2 = - 2 ( for this equation)

Answer:

{1,1,2,2,4,4,8,8}

Step-by-step explanation:

In Finding The Factor Of A Number You Need To Find A multiplication of Two Numbers That Gives The Product 8.

•So keeping this in mind you can make multiples of numbers which has an outcome of 8. So;

1×8=8 {So 1 is a factor of 8 and note that any number multiplied by 1 is the number itself}

2×4=8{Two multiplied by four is going to give you 8 that's why it's a factor of 8}

3×?=8{There is no number which can be multiplied by 3 which has it's outcome as 8 so 3 isn't a factor}

4×2=8{4 multiplied by 2 is the same as 2 multiplied by 4 so you can see that when you multiply two numbers and it has it's product as 8 those two numbers that you multiplied to get the 8 is a factor of 8}

5×?=8{With the number 5 you can see that there is no number which can be multiplied by 5 which has its outcome as 8 so 5 is not a factor of 8}

6×?=8{With the number 6 you will not get any number which can be multiplied by 6 to give you 8 so 6 isn't a factor of 8}

7×?=8{With the number 7 too you won't get any number to be multiplied by 7 which is going to give you 8 that's why it isn't a factor of 8}

8×1=8{With the number 8 you can clearly see that when 8 is multiplied by 1 the product is 8 so that makes it its factor}

After finding the multiplication of Two Numbers that are going to give you 8, you can conclude that you have found the factors of 8 and note that any number above 8 can't be a factor of 8.

So we can conclude that the Factors of 8 are;

{1,2,4,8}

Answer:

i think songs it might be correct but im not sure

The inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is s + 2.50v ≤ 25

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

Let's suppose the number of songs is 's' and number of videos is 'v'

Total cost for songs = $s

Total cost for videos = $2.50v

Patrick has a gift certificate for $25

Then the inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is:

s + 2.50v ≤ 25

Thus, the inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is s + 2.50v ≤ 25

Every morning, I get up and wash my face. Then I sit at my desk and I write. It can be anything. To your future self who will hopefully never read it, a letter to someone you like or don't like regardless of whether you give it to them. Maybe write about what you're feeling in the moments between waking up and sitting down. Don't stop writing until you've emptied your head and put it all on paper.

I don't remember where I learned this but it was called Morning Pages. Some call it Mourning Pages because you're saying goodbye to yesterday and looking forward to the day coming.

Answer: $ 19.44

Step-by-step explanation:

Give : Original price of coloring book = $18

Sales tax = 8% =0.08 [we divide number by 100 to remove %]

Now , the final price of the Anime coloring book = Original price + (Original price) x (Sales tax)

=$ ( 18+18 x 0.08)

= $ (18)(1+0.08)

= $ (18)(1.08)

= $ 19.44

Hence, the final price of the Anime coloring book = $ 19.44

Answer:

$14.00 per pound for A and $12.50 per pound for B and B is offering the better one since it has a lower cost per pound

Step-by-step explanation:

Answer:

Brand A is $14

Brand B is $12.5

Brand B is offering the better value. I know this because when you get the unit rate for Brand A it is $14. When you get the unit rate for Brand B you get $12.5. So You pay less money for Brand B then Brand A.

Step-by-step explanation:

For brand A you need to first divide 70 by 5 which equals to 14

Then you divide 105 by 12 which equals 12.5

Answer:

$434.16346

Step-by-step explanation:

Given that :

Gross earning= $14500

Federal, state and local taxes = 11%

0.11 * $14500 = $1595

FICA tax rate = 7.65%

0.0765 * 14500 = $1109.25

Personal deduction :

3.5% * 14500

0.035 * 14500 = $507.50

Total deduction :

$(1595 + 1109.25 + 507.50)

= $3211.75

Net earning : $(14500 - 3211.75) = 11288.25

Since she is paid bi weekly:

Number of biweeks in a year = 52 /2 = 26

Number of payments per annum = 26

Hence,

Net pay per period :

11288.25 / 26

= $434.16346

Answer:

If you have have 24 coins and 7 pouches, you can put 3.43 coins in each pouch.

Step-by-step explanation:

To solve this you want to divide the 24 coins into 7 pouches.

x = coins

y = pouches

z = how many coins can go in each pouch:

[tex]x/y = z[/tex]

Substitute:

24/7 = z

3.42857142857 = z

round to the nearest hundredth:

3.43 = z

If you have have 24 coins and 7 pouches, you can put 3.43 coins in each pouch.

To figure out how many coins go into each pouch, divide the number of coins by the number of pouches.

Coins per pouch = 24/7 = approx. 3.43

Answer:

Credit card B is a better deal

Step-by-step explanation:

in order to compare both credit cards, we must either convert the APR into a monthly rate or the monthly rate to APR.

convert credit card A's APR to monthly rate:

= 22.45% / 12 ≈ 1.87%, which is higher than 1.25%, so credit card B is better

OR

convert credit card B's monthly rate to APR:

= 1.25% x 12 = 15%, which is lower than 22.45%, so credit card B is better
