PLEASE HELP I AM TIMED !

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

ANSWER: A.10

Ok done. Thank to me :>

Answer:

1000-100=900,900+10=910,910-1=909

Step-by-step explanation:

Hey there!

1,000 - 100 + 10 - 1

1,000 - 100 = 900

= 900 + 10 - 1

900 + 10 = 910

= 910 - 1

= 909

Thus that’s why 1,000 - 100 + 10 - 1 is most likely equal to 909

Good luck on your assignment and enjoy your day!

Answer:

Given : Michael and Imani go out to eat for lunch.

their food and beverages cost $25.30

8% meals tax,

After adding a tip, the total lunch cost was $32.24

To Find : how much is the bill

What percentage tip did they give?

Solution:

food and beverages cost $25.30

8% meals tax,

Tax = (8/100) 25.3 =  2.02 $

BILL = 25.30 + 2.02

= 27.32  $

BILL = 27.32  $

After adding a tip, the total lunch cost was $32.24.

=> Tip = 32.24. -  27.32  = 4.92$

% of Tip  = (4.92 /  27.32) * 100 =  18 %

Tip = 18 %

Step-by-step explanation:

Answer:

Part A:  $28.46

Part B:   8.5%

Step-by-step explanation:

Part A:

We know that in this equation that 25.30 is the 100% number and we need to find 8% of this.

We can then divide  8 by 25.30 which is 3.1625 but the problem asks us to "round to the nearest cent" so we then know that the 8% is $3.16 we have to then add the 8% to the total which would be:      25.30 + 3.16 which equals $28.46 which is your answer to Part A.

Part B:

After adding a tip that problem states that the total went up from $28.46 to $32.24 to find out how much they tipped we can minus these 2 totals to find the difference

32.24 - 28.46 = 3.78

We now know that they tipped $3.78 and we now need to convert this into a percentage.

Right now the whole 100% is $32.24, we then divided 32.24 by 3.78 which would be 8.5291 and so on but wo round this it would be 8.5%

The answer to Part B would be 8.5%

[tex]\dfrac 57 x = \dfrac 17 \\\\\implies 5x =1 \\\\\implies x = \dfrac 15 \\\\\\\text{Hence }~ \dfrac 57 ~ \text{of}~ \dfrac 15 ~ \text{is }~\dfrac 17[/tex]

Answer:

1/5

Step-by-step explanation:

'of' is the same as multilpy

5/7 × ? = 1/7

? = 1/7 ÷ 5/7

? = 1/7 × 7/5 = 7/35

?=7/35

? = 1/5

check answer:

5/7 of 1/5 = 5/7 ×1/5 = 5/35 = 1/7

Let b be the number of blue beads and g the number of green beads that Giovanni can use for a belt.

He's supposed to use a total of between 70 and 74 beads, so

70 ≤ b + g ≤ 74

The ratio of green beads to blue beads is g/b, and this ratio has to be between 1.4 and 1.6, so

1.4 ≤ g/b ≤ 1.6

For completeness, Giovanni must use at least one of either bead color, so it sort of goes without saying that this system must also include the conditions

b ≥ 0

g ≥ 0

(These conditions "go without saying" because they are implied by the others. g/b is a positive number, so either both b and g are positive, or they're both negative. But they must both be positive, because otherwise b + g would be negative. I would argue for including them, though.)

Answer:

11.25 days

Explanation:

15 / 12 = 1.25

1.25 x 0.75 = 0.9275

0.9375 x 12 = 11.25

Answer:

40°

Step-by-step explanation:

According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.

So with this, you need to add 70° and 70°.

You get 140°

Then to find the last angle, you will subtract the 140° by 180°.

180°-140° = 40°

Hope this helped! :)

Answer:

 40

Step-by-step explanation:

First you add 70 and 70 together to get 140 then minus it by 180.

Then you will get 40 degrees as your answer.

Hope This Helps :)

Answer:

46 units

Step-by-step explanation:

So first of all you do 8 × 2 which equals 16 units, then you do 15 × 2 which equals 30 units, then you 30 + 16 which equals 46 units. Hope this helps.

Answer:

There's not really a question to answer there, you've only stated the information that we know. From what I can see the only conclusion I can make is that Sterling plants a tree that is 4 3/4 feet tall, but that's already written and with all the information provided that's really all I can say.

Sorry if that's not exactly what you were looking for, maybe if there's more to the question re-post it with the entire question?

Answer:

A. -102 + 25.5.

Step-by-step explanation:

After multiplying 51 by -2.0, you will get -102. When multiplying 51 by -0.5, you get 25.5. A is the next step in this equation. (Optional answer: read this when this is also in your quiz. -102 + 25.5 = 127.5).

Answer:

$145.80

Step-by-step explanation:

The original cost of the product was $90.  There was a 162% markup.  In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%).  After taking away 100%, I am left with 62%.  I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8.  Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.

Answer:$145.80

Step-by-step explanation:

Step-by-step explanation:

ab                 =>    (5)(6) = 30

b + 3             =>    6 + 3 = 9

a + b + c       =>    5 + 6 + 7 = 18

3b + 4          =>    3(6) + 4 = 22

5a - c           =>    5(5) - 7 = 18

Answer:

The correct answer is:

The equation has no solution; therefore, the system of equations has no solution.

Step-by-step explanation:

When solving a system of equations, after we combine the equations, if we find that there is no solution, that means that there is no solution to the entire system of equations.

Answer:

y + 7 = (-14/17)(x - 8)

Step-by-step explanation:

We want the equation of this line in the point-slope form y - k = m(x - h).

We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above.  Then the other point is represented by (x, y) in the point slope form shown above:

Let (h, k) be 8, -7) and let (x, y) be (-9, 7).  Then,  y - k = m(x - h) becomes:

7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17

The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).  

Another way to get this result would be to find m in the usual way:

          rise           14

m = ------------- = --------- = -14/17 (same as before).

           run           -17

Answer:

2.5x > 25

Step-by-step explanation:

1. 10 + 2.5x > 35

2. 10 + 2.5x - 10 > 35 - 10 (Subtracting 10 from both sides)

3. 2.5x +10 - 10 > 35 - 10 (Group like terms)

4. 2.5x > 35 - 10 (Simplify the arithmetic)
