An employee makes an hourly rate plus any tips they earn. This tip employee made a total of $400 by working 28 hours last week. If $253 of their total earnings was their tips, what is their hourly rate of pay?

Answers

Answer 1

Answer: To find the answer we must remove the tips amount from the total amount, and then divide what remains by the numbers of hours he worked. So we have: HourlyRate = (400 - 253) / 28 <=> HourlyRate = 147/28 <=> HourlyRate = $5.25

Answers

You just have to try them all:
Y=x+3 ≈ 6=3+3 ≈ 6=6 √
Y=x+3 ≈ 8=4+3 ≈ 8=7 X
So the first function doesn't work

Y=2x ≈ 6=2(3) ≈ 6=6 √
Y=2x ≈ 8=2(4) ≈ 8=8 √
Second function works

Y=x+4 ≈ 6=3+4 ≈ 6=7 X
Third function does not work

Y=12-x ≈ 6=12-3 ≈ 6=9 X
Fourth function doesn't work

So your answer is Y=2X :)

Answer:

The solutions to the quadratic equation are: $x=-2+√(5),\:x=-2-√(5)$

Step-by-step explanation:

To solve the quadratic equation $3x^2+12x=3$ you must:

Subtract 3 from both sides and simplify

$3x^2+12x-3=3-3\n\n3x^2+12x-3=0$

For a quadratic equation of the form $ax^2+bx+c=0$ the solutions are

$x_(1,\:2)=(-b\pm √(b^2-4ac))/(2a)$

$\mathrm{For\:}\quad a=3,\:b=12,\:c=-3$

$x=(-12+√(12^2-4\cdot \:3\left(-3\right)))/(2\cdot \:3)=(-12+√(180))/(2\cdot \:3)=(-12+6√(5))/(6)=(6\left(-2+√(5)\right))/(6)=-2+√(5)$

$x=(-12-√(12^2-4\cdot \:3\left(-3\right)))/(2\cdot \:3)=(-12-√(180))/(2\cdot \:3)=(-12-6√(5))/(6)=-(6\left(2+√(5)\right))/(6)=-2-√(5)$

The solutions to the quadratic equation are:

$x=-2+√(5),\:x=-2-√(5)$

$3 x^(2) + 12x = 3$
$3 x^(2) + 12x - 3 = 0$
Using the quadratic formula
$x = \frac{-b (+ or -) \sqrt{b^(2 - 4ac) } }{2a}$
$x = \frac{-12 + \sqrt{12^(2 - 4(3)(-3)) } }{2(3)}$ OR $x = \frac{-12 - \sqrt{12^(2 - 4(3)(-3)) } }{2(3)}$
$x = (-12 + √(180) )/(6)$ OR $x = (-12 - √(180) )/(6)$
∴ x = 0.236 and x = -4.236

Out of the 180 students at a summer camp, 72 signed up for canoeing. There were 23 students who signed up for trekking, and 13 of those students also signed up for canoeing.Use a two-way table to organize the information and answer the following question:

Approximately what percentage of students signed up for neither canoeing nor trekking?

72%
40%
54%
98%

Answers

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

Total number of students = 180

Number of students who signed for canoeing (C) = 72

Number of students who signed for trekking (T) = 23

Number of student who signed for trekking is also signed for canoeing = 13

Number of students who only signed for canoeing (C) = 72-13=59

Number of students who only signed for trekking (T) = 23-13=10

So, Number of students who signed up either for canoeing or trekking is given by

$n(C\cup T)=n(C)+n(T)-n(C\cap T)\n\nn(C\cup T)=72+23-13\n\nn(C\cup T)=95-13\n\nn(C\cup T)=82$

So, Number of students who signed up neither for canoeing not trekking is given by

$n(C\cup T)'=n(U)-n(C\cup T)\n\nn(C\cup T)'=180-82\n\nn(C\cup T)'=98$

So, Percentage of students signed up for neither canoeing nor trekking is given by

$(98)/(180)* 100\n\n=54.4\%\n\n\approx 54\%$

Hence, Third option is correct.

that is 72%of the kids

C. What is the square root of 81?

A. 9

B. 27

C. 18

D. 36

Step-by-step explanation:

1. A is the correct answer. 9/3 / 2/5, reciprocal is the one you use to solve it. 5/2 x 9/3

45/6 = 6 3/6

6 1/2

2. You need to divide $15/25 as a number, to find the unit rate, giving you $0.60. 6 is the correct answer.

3. A is the correct answer. 9 x 9 equals 81, so therefore 9 is the correct answer.
