Answer:

Step-by-step explanation:

Step one:

given data

we are told that the cost of the meal is $45.50

the amount of the tip is 20% of the cost of the meal.

let 20% of $45.0 be x

Step two:

So, let us solve for 20% of $45.50

which is 20/100*45.50

x=0.2*45.5

x=9.1

This shows that the amount of the tip is $9.1

Answer:

D.

Step-by-step explanation:

115x + 170 = 630

Subtract 170 from each side of the equals,

115x = 460

Divide 460 by 115,

4

Thus, D is your correct answer.

Answer:

60 yds

Step-by-step explanation:

10 + 15 + 4 + (10 - 4) + 20 + (20 - 15) = 60

Answer: 60 Yards

In this model, we have all sides except for two. In order to find the perimeter of this, you would need all sides.

To find the missing sides you can see that the lenght of the side on the left is 10 yards. And the entire right side is equal to that left side. So, to find the missing side x you would need to solve: x+10-4. So, x is 6.

Do the same for the top and bottom to get the other missing side that is perpendicular to the side that is 4 yards is 5 yards.

Now that you have the lengths of all of the sides, you can solve for the perimeter. You would do,

[tex]15+4+6+20+10+5=60[/tex]

Answer:

Step-by-step explanation:

x + x + 2 = 86       Two even numbers add to 86

2x + 2 = 86           This is the equation. Subtract 2 from both sides

2x = 86 - 2              

2x = 84                  Divide by 2

2x/2 = 84/2

x = 42

Answer:

The equation after applying the Distributive property:

6 = 9x + 27

The equation solved:

x = -2.33333333

Step-by-step explanation:

The distributive property means that you will multiply the items inside of the parenthesis by the number right out side, in this case (x + 3) by 9.

9 * x = 9x

9 * 3 = 27

our new equation will look like:

6 = 9x + 27

now we will be able to solve!

let’s start by subtracting 27 from both sides.

27 - 27 = 0

6 - 27 = -21

9x = -21

divide both sides by 9.

9x/9 = x

-21/9 = -2.33333333

x = -2.33333333

The value of x from the given equation is x=-7/3.

The given equation is 6=9(x+3).

The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC.

Using distributive property

6=9(x+3)

⇒ 6=9x+27

⇒ 9x=-21

⇒ x=-21/9

⇒ x=-7/3

Therefore, the value of x from the given equation is x=-7/3.

Answer:

Step-by-step explanation:

The two sides add up to 12. If the third "side" of the triangle is 12, then 5 and 7 will lie horizontally on 12.

So the maximum value must be less than 12. What's the smallest x could be?

well 5 + something must be > than 7. If they are not larger than 7, then 5 and something will lie on 7 just as it did before. So how big is something?

5 + y > 7

5 - 5 + y > 7 - 5

y > 2

So the range    is  2 < x < 12

How else could you write this?

2 < x

x < 12 is one way.

Answer:

Step-by-step explanation:

Given the approximate demand function of night drink expressed as;

p^2+200q^2=177​,

p is the price​ (in dollars) and;

q is the quantity demanded​ (in thousands).

Given

p = $7

q = 800

Required

dq/dp

Differentiating the function implicitly with respect to p shown;

2p + 400d dq/dp = 0

400q dq/dp = -2p

200qdq/dp = -p

dq/dp = -p/100q

substitute p and q into the resulting equation;

dq/dp = -7/100(800)

dq/dp = -7/80000

dq/dp = -0.0000875

This means that the rate of change of quantity demanded with respect to the price is  -0.0000875

∠3 is a verticle angle to ∠1

linear pair means they add up to 180

complementary mean they add up to 90

Answer:

None of the answers are correct.

Step-by-step explanation:

1 and 8 are corresponding angles.

They are not vertical because vertical angles look like this ><

They are not a linear pair because linear pairs = 180 and right next to each other.

They are not complementary angles because complementary angles = 90

Answer:  She will have to spend 8 days on vacation before she will have bought a total of 16 souvenirs.

Step-by-step explanation:

Given: Ann bought 4 souvenirs during 2 days of vacation.

Per day she buys =[tex]\dfrac{4}{2}=2[/tex] souvenirs  [unit rate]

To buy 16 souvenirs , she will take [tex]\dfrac{16}{2}[/tex]  = 8 days.

Hence, she will have to spend 8 days on vacation before she will have bought a total of 16 souvenirs.

Answer:

Step-by-step explanation:

Rob needs 43.2 feet of border to place around the ceiling and Rob will have 6.8 feet of border left after placing it around the ceiling.

What is distance?

Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet. Distance is a scalar quantity, meaning it has only magnitude and no direction.

The perimeter of the ceiling is equal to the total length of border that Rob will need. The perimeter of a square is given by the formula P = 4s, where s is the length of one side of the square.

In this case, the length of one side of the square ceiling is 10.8 feet, so the perimeter is:

P = 4s = 4(10.8) = 43.2 feet

Therefore, Rob needs 43.2 feet of border to place around the ceiling.

Since he has purchased 50 feet of border, he will have:

50 - 43.2 = 6.8 feet

Rob will have 6.8 feet of border left after placing it around the ceiling.
