How -15 + 8 gives me 7 ????????

Answers

Answer 1
it doesn’t give you 7
it gives you -7
because when you add 8 to negative 15, you’re just basically subtracting it to give you -7
Answer 2

Answer:

It gives you -7

Step-by-step explanation:

Think of the problem as 8 - 15, because 8 is a smaller number and 15 is bigger, you'll get a negative number.

The next step is use the rule**a-b = -(b-a)**which is - (15 - 8)

Then when you simplify it, it will be - (15 - 8)= - 7**(which is the answer)

Hope this helps:)

Answer:

11.25 or 11 1/4

Step-by-step explanation:

seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole

so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-

now we need the dimensions of each one-

rectangle one

l=5 w=2

rectangle two

l=5 w=1/4

now let us set up the equation and solve-

a=lw

rectangle one

a=5*2=10

rectangle two

a=5*1/4=1.25

and the last step is to add together the areas of both rectangles

10+1.25=11.25

and since you need your answer as a mixed number the answer is 11 1/4

(to do this you just put 11.25 over 100 and then simplify)

good luck :)

i hope this helps

Answers

9514 1404 393

Answer:

  C.  35.3 km

Step-by-step explanation:

From your knowledge of right triangles, you know that the hypotenuse is longer than the longest leg and shorter than the sum of the legs.

For this geometry, the distance of interest is longer than 32 km and shorter than 15+32 = 47 km. The only answer choice in the correct range is ...

  35.3 km

A. Answer:$3
B.Equation:12+4x=40
C. Equation:4+12x=40
D. Answer:$7

Answers

Answer:

D. $7

Step-by-step explanation:

i think it would be "D". the reason why i chose that answer is because first of all the total they spent is $40 right? as we see in this equation, paige and her family purchased $12 for popcorn. what does that mean? it means that 40-12= $28 that is left. the money that is left is the total of all 4 tickets. 28 divided by 4 is 7 so the answer is $7

A model rocket is launched with an initial upward velocity of 62/ms. The rocket's height h (in meters) after t seconds is given by the following.
h=62t-5t^2
Find all values of t for which the rocket's height is 29 meters.
Round your answer(s) to the nearest hundredth.

Answers

9514 1404 393

Answer:

  t = 0.49, 11.91

Step-by-step explanation:

A graphing calculator can show you the answers quickly. The times are 0.49 seconds and 11.91 seconds.

__

We can write the equation as ...

  h = 29

  62t -5t^2 = 29 . . . . . substitute for h

  -5(t^2 -12.4t) = 29

  -5(t^2 -12.4t +6.2^2) = 29 -5(6.2^2) . . . . complete the square

  -5(t -6.2)^2 = -163.2 . . . . . simplify

  t -6.2 = ±√(-163.2/-5) = ±√32.64 . . . . divide by -5, take the square root

  t = 6.2 ±5.71

  t = 0.49, 11.91

The rocket has a height of 29 meters at t=0.49 seconds and t=11.91 seconds.

You buy a new backpack that costs $62.00. The sales tax is 6.5%. What is the total amount you need to pay, including tax? ​

Answers

Answer:

$66.03 in total.

Step-by-step explanation:

$66.03 because 6.5% is 0.065 and $62.00 times 0.065 equals $4.03. $62.00 plus $4.03 is $66.03.

ENTERTAINMENT For Exercises 19 and 20, use the following information.
Fairfield High spent d dollars for refreshments, decorations, and advertising for a dance. In
addition, they hired a band for $550.
19. Write an expression that represents the cost of the band as a
fraction of the total amount spent for the school dance.
20. If d is $1650, what percent of the budget did the band account for?

Answers

Answer:

D + 550 = X

The band accounted for 25% of the budget.

Step-by-step explanation:

Since Fairfield High spent D dollars for refreshments, decorations, and advertising for a dance, and in addition, they hired a band for $ 550, to write an expression that represents the cost of the band as a fraction of the total amount spent for the school dance and determine, if D is $ 1650, what percent of the budget did the band account for, the following calculations must be performed:

D + 550 = X

D = 1650

1650 + 550 = X

2200 = X

2200 = 100

550 = X

550 x 100/2200 = X

55,000 / 2,200 = X

25 = X

Therefore, the band accounted for 25% of the budget.

Two friends, Chespirito and Quico, are racing down a mountain. Quico is 17.6 miles away from the Finish Line and runs 2.6 miles per hour. Chespirito is 22.8 miles from the Finish Line, but runs 3.9 miles per hour. How many hours will it take Chespirito to catch up with Quico? It will take Chespirito hours to catch up with Quico.

Answers

Answer:

4 hrs

Step-by-step explanation:

22.8-17.6=5.2

so they are 5.2 miles apart.

Let they meet after t hrs.

distance coverd by Quico in t hrs=2.6t

distance covere by Chespirito in t hrs =3.9t

3.9t-2.6 t=5.2

or 1.3 t=5.2

t=5.2/1.3 =4
