Answers

Answer 1

Perimeter of her rectangular back yard is: 200 ft

⇒ 2(30 + 60 + x) = 200

⇒ 30 + 60 + x = 200/2 = 100

⇒ 90 + x = 100

⇒ x = 100 - 90 = 10

A store advertises a 35% markdown on the PlayStation 5 gaming console. It normally sells for $1,019. what is the final sale price?

Answers

the final sale price would be $662.35

ANSWER: $662.35

EXPLANATION:

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.

When we do this we get $662.35

Evaluate the expression when b=9 and c=4 . bc+12.3 =

Answers

48.3

9*4 = bc, equals 36
36+12.3, equals 48.3

48.3 because when two letters are next to each other and they are worth a number you multiply them for example 9(4)+12.3 so first you multiply 9 and 4 you should get 36 then you add 12.3 which will get you 48.3

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.

Answers

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

The correct answer is B!

Answer:

The answer is B) a = -7/16

Step-by-step explanation:

3/4 + 4a/7 = 6a/7 + 7/8

By transposing, we get

=> 3/4 - 7/8 = 6a/7 - 4a/7

=> (by taking LCM) 6-7/8 = 6a-4a/7

=> -1/8 = 2a/7

=> -7 = 16a (by cross multiplication)

=> a = -7/16

then second position is filled in 3 ways since for first position we used a digit

and the condition is that not to repeat the digits, so it is done in 3C1 ways.

-2x <-12

solve the inequality

Answers

Answer:

x > 6

Step-by-step explanation:

-2x < -12

divide by -2

switch signs because you're dividing by a negative number

-2x/-2 < -12/-2

x > 6

Hope this helps :)

Answer:

x > 6

Step-by-step explanation:

Solve -2x <-12 for x. Your answer must be a set of real numbers.

Divide both sides by -2. Note that if we here divide by a negative number, we must reverse the direction of the inequality symbol:

-2x < - 12

----- ------

-2 -2

This becomes x > 6, "the solution set"

Rewriting the original quantities as improper fractions, we get

A line passes through (2, 8) and (4, 12). Which equation best represents the line?
1. y = 1/2x + 6

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

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!
