Melanie earns average tips of 18% while waiting tables. If her sales one night were $730.84, what did she make in tips?

Answer:

256

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

Domain is the set of x values or input values of a function.

Range is the set of y values or output values of a function.

Given relation is,

2x + y = 4

Set if input values of domain → {-5, 0, 6}

Table for the input - output values,

x       -5        0        6  

y       14        4       -8  

Therefore, range of the given relation will be the set of output values.

{14, 4, -8}

Option A is the answer.

Answer:

90

Step-by-step explanation:

Answer:  The shadow of the tree is 280 feet long.

Step-by-step explanation:

We can use a ratio to solve this:

Use the Height to shadow for each. This works because the fractions must reduce to the same equivalent.

5/10 = 140/x

We can see that 5/10 is 1/2, so we need another fraction using 140 as the numerator that is equal to 1/2.  That's easy here: Multiply 140 × 2 to get the new denominator, 280 that replaces x. That is the length of the shadow.

If you have a less obvious ratio, you can use Cross Multiplication to solve the unknown value in the ratio:

5/10 = 140/x  Cross multiply the numerator of the left side times the denominator on the right side, and the denominator on the left side by the numerator on the right side:

5 × x = 10 × 140

5x = 1400  Divide both sides by 5 (the 5s "cancel" on the left)

5x/5 = 1400/5

x = 280

I hope this helps, especially when you see more questions like this in the future.

Step-by-step explanation:

3= a -1

+1 = a. you pass the negative 1 to the other side.

and it turns to a + 1 and then you add it which

gives you 4

Answer:

Radius

314 cm²

Step-by-step explanation:

They gave you the diameter which you can find the radius from, and you need the radius to find the area. The radius is 10, and that squared is 11. Multiply 3.14 times 100 to get 314.

Answer:

$480

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Original cost including sales tax = $1,200

Discount = 60%

So, we can calculate the cost of TV after discount by using following formula:

Cost of TV after discount =  $1,200 - ( $1,200 × 60%)

= $1,200 - $720

= $480

Hence, Cost of TV after discount is $480.

To solve this, all you need to do is compare the ratio to the amount of SUVS there are.

5/9 (SUVs to sedans)

140/? (SUVs to sedans)

140 ÷ 5 = 28

9 x 28 = 252

140/252

There are 252 sedans in the car dealership! :D

Answer:

252 Sedans

Answer:

Step-by-step explanation:

for 3x +y = -5

it's [tex]x = \frac{-5 -y}{3}[/tex]

and for 2x + 3y = -8 it's

[tex]x = \frac{-8 - 3y}{2}[/tex]

Hi. you've asked an incomplete question. However, I provided some explanation about algebraic expressions and numerical expression.

Step-by-step explanation:

First, we may wonder: What is a numerical expression? In simple words, they are mathematical expressions that contain numbers and operations (like +, -, ÷, ×).

For example, 7+70, 90-10, 60÷10, 5×4 are numerical expressions.

While an algebraic expression on the other hand is a mathematical expression that contains at least one variable.

Variables are letters or symbols (like x, y, p, q, etc) that represent an unknown number or value in a mathematical expression.

For example, 7x+70, 90y-10 are algebraic expressions since they contain at least one variable.

Answer:

25/32 kg

Step-by-step explanation:

The kinetic energy K of a body in motion measured in joules is given as

K = 1/2 mV^2

Where n is the mass in kg and V is the speed in m/s

Hence given that K is 25J and speed V is 8 m/s,

25 =1/2 * m * 8^2

25 = m *32

Divide both sides by 32

m = 25/32 kg

Answer:

8

Step-by-step explanation:

8/2 equals 4 minus 10 is -6

Answer:

-6= n/2 -10

-12=n-20

-12-n=-20

-n=-20+ 12

-n=-8

n=8

Step-by-step explanation:

1. multiply both sides of the equations by 2

2.Move the N varaiableto the left hand side and change its sign

3. Calculate the sum of -20+12

4. change the signs from negative N to positive N giving you the value of 8

n=8

Solved.

$200

Step-by-step explanation:

80% 200 is equal $132

Answer:

Please check the explanation.

Step-by-step explanation:

Given

C=24x+80

R=44x

To determine

What is the break-even point?

Given that

C represents the cost in dollars

R represents the revenue in dollars.

At the break-even point Cost (C) equals Revenue (R), so

R = C

44x = 24x+80

44x-24x = 80

20x = 80

divide both sides by 20

20x/20 = 80/20

x = 4

Thus, at x = 4 the value of Cost (C) equals Revenue (R).

i.e.

C = 24x+80 = 24(4)+80 = $176

R = 44x = 44(4) = $176

Answer:

(4, 176)
