During a period of extreme cold, the average daily temperature dropped decreased by 112°F day. How many days did it take for the temperature to decrease by 9°F? Which equation would you use to find the solution?

A x + 112 = 9x + 112 = 9

B x − 112 =−9x − 112 =−9

C −112x = −9−112x = −9

D 112x = 9

Answers

Answer 1

It takes about 4 days for the temperature to decrease by 9°F.

An equation is an expression that shows the relationship between two or more variables or numbers.

Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):

-1 1/2 * x = -9

-1.5x = - 9

x = 4 days

It takes about 4 days for the temperature to decrease by 9°F.

Answer:

38 7/18

Step-by-step explanation:

The LCD of denominators 3, 9 and 2 is 72; all three of these divide evenly into 72.  Rewriting the original problem, we get

7 24/72 - 5 64/72 + 8 36/72

Rewriting the original quantities as improper fractions, we get

22/3 - 53/9 + 17/2

Applying the LCD, we get

24(22)       8(53)       17(36)        2764

----------- - ----------- + ---------- = ------------ = 38 7/18

   72             72           72             72

[tex]7\frac{1}{3}-5\frac{8}{9}+8\frac{1}{2}= \frac{22}{3}-\frac{53}{9} +\frac{17}{2} = \frac{132}{18}-\frac{106}{18}+\frac{153}{18} =\frac{132-106+153}{18} =\frac{179}{18}=9\frac{17}{18}[/tex]

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

Answers

112.5 seconds

First convert minutes to seconds so 7 x 60 + 30, that will get you the total seconds and should equal 450 secs. Divide that by 4: 450 / 4, equals 112.5 seconds

Answer:

112.5 seconds

Step-by-step explanation:

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.

Remember

1 minute = 60 seconds.

So do 7 times 60.

7 × 60

Which is 420 seconds.

Now add the 30 seconds to that.

420 + 30.

Which is 450 seconds.

Now divided 450 by 4.

450 ÷ 4.

Which is 112.5 seconds per lap.

A garden hose was left on in a yard and spilled 78 gallon every 23 minute. Find the average number of gallons spilled per minute.

Answers

Answer:

3.391 Gallons Per Minute

Step-by-step explanation:

78/23=3.391

Round 3.391 to 3.4

Answer:

≈3.39130434783 gallons per minute

Step-by-step explanation:

The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:

[tex]78 : 23[/tex]  OR  [tex]\frac{78}{23}[/tex]

We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:

[tex]\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}[/tex]

And of course, if there's a need to round, go ahead.

And please do not waste water!

2. y = 2x + 7

3. y = 2x + 4

4. y = 1/2x + 10

Answers

y=2x+4 because we’re moving up 2 units for every unit we move to the right, and if we plug 0 in for X we end up with the +4
I would say 3 (I am not completely positive, I am not that smart with graphs)

X: (2 + 4) / 2 Equals: 3
Y: (8 + 12) / 2 Equals: 10
Then multiple 3 by 2 get 6, add four, you get 10 which is equal to Y

Answer:

  1) 2^9 = 512

  2) 2^(3t) = 2^6 for t=2

Step-by-step explanation:

1) An exponent is used to signify repeated multiplication. Here, the factor 2 is repeated 9 times, so the expression can be written using an exponent as ...

  2^9

Using any of a variety of means, the value of this expression can be found to be ...

  2^9 = 512

__

2) Assuming the bacteria reproduce by multiplying by some factor in a given time, we can divide the original expression into 3 parts:

  (2×2×2) × (2×2×2) × (2×2×2)

If this represents the number after 3 hours, then the number after 2 hours is expected to be ...

  (2×2×2) × (2×2×2) = 2^6

That is, there will be (2 h)/(3 h) = 2/3 times as many multiplications by a factor of 2. (2/3)(9) = 6 will be the exponent for the number after 2 hours.

1. 2^9 = 512
2. as you can split up the fact in 3 hours it is 2^9 to find out one hour (divide by 3) which is 2^3 so we would just multiply it by 2 which equals 2^6

We know the how much the PS5 cost and we know the markdown percentage. So we need to find 35% of 1,019 because we need to know how much to take away.

35% of 1,019 = 356.65

So now we take the original price and subtract 356.65 from 1.019.
