Answer:

Henry had 12 cans of Xtreme diet soda, if he drinks 2 sodas each hour and ends up with 8 cans at the end of the day, how many hours did he drink?

Step-by-step explanation:

12-2h=y

y=8 and your final amount

h = hrs and your variable

12 is your constant! he only has 12 cans, which cannot change

2 is your coefficient, but you can change it to whatever you want

If you need clarification let me know!

Answer:

x= -1 y=3

Step-by-step explanation:

Answer:

x = -1

y = 3

Step-by-step explanation:

2x +y =1 3x -y= -6

Add the two equations together to eliminate y

2x +y =1

3x -y= -6

------------------

5x = -5

Divide by 5

5x/5 = -5/5

x = -1

2x+y = 1

2(-1) +y = 1

-2 +y =1

Add 2 to each side

y = 1+2

y =3

Answer:

The question seems incomplete, but this statement would be true for all x below 3 (you can put any number less than 3 in it and get a true statement)

step one it says Jasmine ran 22 km is approximately equal to 1.6 km in which measurement is closest to the number of miles Jasmine ran the correct answer is C

Answer:

A = 8

B = 6

C = 4

D = 7

Top = 29

Side = 20

Step-by-step explanation:

To get A on the bottom side row you divide 32 by 4 and get 8.

To get D, on the first side row, subtract A, 8, now it's 21, 21 divided by 3 is 7.

To get B, on the first top row, subtract A and D, now divide by 2 and you get 6.

To get C, on the third side row, subtract B and divide by 2 and you get 4.

Answer:

An equation with -8 as the slope.

Step-by-step explanation:

I can't see your choices but you need to look for an equation in which the slope is -8. A line with an opposite reciprocal slope is needed in order to be perpendicular to the line y = 1/8x + 3. The opposite reciprocal of 1/8 is -8.

Answer:

Answer: A

x-2

Step-by-step explanation:

Questions 1:

√(x²-10x+25)

x²-10x+25= (x-5)²

√(x-5)²= x-5

question 2:

x²-4x+4= (x-2)²

√(x-2)²= x-2

Answer:

10

Step-by-step explanation:

5(3r - 10)

Let r = 4

5(3*4 - 10)

5( 12 - 10)

5 (2)

10

Answer:

10

Step-by-step explanation:

5(3r-10)

5(3(4)-10)

so forget the 5 and solve inside first

3*4= 12

12-10= 2

now bring the 5 back and multiply

5*2= 10

Answer:

Step-by-step explanation:

∠1 + ∠2 + ∠3 + a = 360   {Sum of all angles of quadrilateral}

76 + 27 + 17 + a = 360

          120 + a = 360

                    a = 360 -120

a = 240°

a + ∠4 = 360    

240 + ∠4 = 360

∠4 = 360 - 240

∠4 = 120°

Step-by-step explanation:

Answer:

-x²+8x-15

Step-by-step explanation:

There are two solutions: 3 and 5

First, let's write the equation in this form (pay attention, the parabola here is going up so it won't be like your graph):

(x-3)(x-5)

For resolve our problem, let's re-write it with a minus before:

-(x-3)(x-5)

You can also expand it and the result will be like this:

-x²+8x-15

Answer:

She buys 5 boxes of popcorn and 6 boxes of candy

Step-by-step explanation:

this is because 5 times 4.00 is 20$ and 2.50 times 6 is 15$

15 + 20 is 35

so your answer is 5 boxes of popcorn and 6 boxes of candy

hope this helped :D

Answer:

B

Step-by-step explanation:

If she spent 35$ and got 1 more candy and popcorn that only leaves a single option

Answer:

[tex]H=20(0.8)^{n}[/tex]

Step-by-step explanation:

So, lets just go over this step by step and make sense of it.

20 clearly must be what we start with, and as you see in your answers, all of them have that as the number you multiply the parethese by.

Its what next that we dont know about.

We know that the ball rebounds 80% of its previous height.

It for sure cannot be a or d because a would mean that it would only rebound 20% of its height, and d would mean that it rebound 180% of its height.

Its now between b and c.

Lets just think about it.

Pull out your calculator or pull it up on your electronic. Multiply 10 by 0.9. This will get you 9. Multiply 9 again by 0.9, and youll get 8.1.

What did we actually do there? We did 10*0.9^2

Pull out your calculator again and try 10* 0.9^2. Youll see that 0.9 squared is 0.81. This times 10 is 8.1, and that is exactly what you got before.

Understanding this, it is clear that we must use an exponent to fidn future values.

In answer b, it shows that you can just multiply by n.

In answer c however, it uses n as an exponent, which is the correct thing to do.

So c is your answer.

The actual formula for this is: [tex]first_.term(change)^t^e^r^m ^[/tex]

The first term in this case is the first height, which is 20. The change is a rebound of 80%(0.8).

The term is just n, but in most problems n is time.

Hope this helps!

Answer:

Step-by-step explanation:

take 60 degree as reference angle

using cos rule

cos 60=adjacent/hypotenuse

1/2=80/x(do cross multiplication)

80*2=x

160=x

Answer:

x = 160

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{CD}{CE}[/tex] = [tex]\frac{80}{x}[/tex] ( multiply both sides by x )

x × cos60° = 80 ( divide both sides by cos60° )

x = [tex]\frac{80}{cos60}[/tex] = 160

Answer:

8 x 8 = 64

64 x 6 = 384 ft^2 is your answer.

Answer:

384 Sq ft

Step-by-step explanation:

multipliy 8 by 8 to get the area of one side. then because it is a cube, and all the side lengths are the same, you can just multipliy the area of one face by the amount of faces total.

8×8=64

64×6=384

384 ft²

or

384 Sq ft

Answer:

Perimeter = AB + AC + BC = 26.55 units

Step-by-step explanation:

The perimeter of a triangle is the sum of lengths of all sides.

Here we have a right triangle, right-angled at C

angle B = 46°

AB = 11

We continue to calculate

AC = (11)sin(46°) = 7.91

BC = (11)cos(46°) = 7.64

Perimeter = AB + AC + BC = 26.55 units

Answer:

  n = 24

Step-by-step explanation:

Multiply the given equation by the product of denominators. Then subtract 6n and go from there.

  [tex]\dfrac{6}{n-6}=\dfrac{8}{n}\\\\6n=8(n-6)\qquad\text{rid of fractions}\\\\0=2n-48\qquad\text{subtract 6n, simplify}\\\\0=n-24\qquad\text{divide by 2}\\\\\boxed{24=n}\qquad\text{add 24}[/tex]

_____

Alternate solution

Any proportion can be written 4 ways. If we write this one "sideways," we have ...

  6/8 = (n -6)/n

  1 -1/4 = 1 -6/n . . . . . expand in parallel fashion

  6/n = 1/4 . . . . . . . . subtract 1, multiply by -1

  n = 24 . . . . . . . . . multiply by 4n

__

Another alternate solution (can be done mentally)

The above "sideways" proportion can be reduced to ...

  3/4 = (n -6)/n

The difference between values on the left is 1 unit. On the right, the difference between values is 6. (The numerator is 6 less than the denominator.) The denominator on the left (4) is 4 times the difference, so the denominator on the right (n) will likewise be 4 times the difference: n = 4·6 = 24. Check: 3/4 = 18/24.

Let the number missed = x

They made 6 times that amount which would be 6x

The total of missed and made is 308:

X + 6x = 308

Combine like terms

7x = 308

Divide both sides by 7

X = 44

They missed 44
