Answer 1
1a) To find the total area, you must find the area of the triangular part that is missing, then subtract this from the area of the rectangle. For the triangle’s area, you need to know the width (2m) and length (2m). For the rectangle’s area you need to know the width (3m) and length (4m).
1b) the total area is 10m^2 (10 meters squared). This is found by subtracting the triangle (.5x2x2=2) from the rectangle (3x4=12).

The answer is H because if you use a calculator and do 5.75 - 3.50 you would get 2.25 then count out how many 0.25 would make 2.25

Answer:H

Step-by-step explanation:

Because 0.25 x 9 will give you 2.25. Then add that to the original number; $3.50 + $2.25 = $5.75. Hope this helps :)  

Which equation is NOT equivalent to 5 + n = 10. Select all that apply.




5 + n -n = 10 – n

5 + n – 5 = 10 - 10

5 + n – 5 = 10 - 5

5 + n + 3 = 10 + 3

5 + n – 10 = 10 - 5

Answers

Answer:

5 + n - 5  = 10 - 10

Step-by-step explanation:

if you do 5-5 that would equal zero, and if you do 10-10 it would equal 0 also, so all you would be left with is 0 + n= 0 and that is not equal to 5 + n = 10

Answer:

5 + n - 5  = 10 - 10

Step-by-step explanation:

Marissa collects donations for a dance marathon. One group of sponsors will donate a total of $25 for each hour she dances. Another group of sponsors will make a one-time donation of $100 regardless of how long she dances. What number of hours should she dance if she wishes to raise at least $500?

Answers

Answer:

20 hours

Step-by-step explanation:

25x20=500

The one time donation will not fufill the needs, but the payment each hour will help Marissa reach her donation goal.

One group giving $100 regardless how long but one donating $25 per hour. So $100+25(hours)= 500 to find the solution since they need $500 deduct $100 then it’s 400 divided by 25 which is 16 hours so

$100+25(16)=500 hours. So 16 hours

Find the value of n.

(-y + 5.3) + (7.2y - 9) = 6.2y + n

Transfer 6.2y to the other side and change its sign.

(-y + 5.3) + (7.2y - 9) - 6.2y = n

Solve for the value of n.

-y + 5.3 + 7.2y - 9 - 6.2y = n

group like terms

-y + 7.2y - 6.2y + 5.3 - 9 = n

0 + (-3.7) = n

-3.7 = n

Substitute n with its value.

(-y + 5.3) + (7.2y - 9) = 6.2y + n

(-y + 5.3) + (7.2y - 9) = 6.2y + (-3.7)

-y + 5.3 + 7.2y - 9 = 6.2y - 3.7

Group like terms

-y + 7.2y + 5.3 - 9 = 6.2y - 3.7

6.2y - 3.7 = 6.2y - 3.7

Hope this Helps

1. 6/15, or 2/5.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

8/15 because 2/15 *3 is 6/15 + 2 is 8 and you multiply by 3 because 60/20=3

Answer:

x/3.5h = -$1.4

So, x = -$1.4 * 3.5h

= -$4.9

Step-by-step explanation:

Since your losing $1.4 every hour, the 1.4 is supposed to negative.

Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours

and get  -$4.9.

Step-by-step explanation:

for it to be a function X (-8) can only have one outcome, however that isn't the case with A.

and I believe if I'm remembering correctly, one-to-one correspondence is each element of one set is only paired with one element of the other set which isn't true for B, so it should be f (x), though you may want to look it up for yourself to make sure.
