Peggy works as a busperson and earns \$7.50/h. She also receives 9\% of the gratuities earned by all the staff. In one week she worked 35 hours and the gratuities totalled \$1936.80. What was Peggy's gross pay?

Answers

Answer 1
Answer:

Answer: $ 436.81

Step-by-step explanation:

Given: Hourly rate for Peggy= $7.50

Also, she receives 9% of the gratuities earned by all the staff.

Total hours she worked = 35 hours

Total gratuities = $1936.80

Gross pay = (Hourly rate ) x (Number of hours worked)+ 9% of (Total gratuities )

= $ [(7.50 ×35)+(0.09 ×1936.80)]

= $ (262.5  +174.31)

= $ 436.81

Hence, her gross pay = $436.81

If y=7.5 when x=0.5, find y when x=-0.3

Answers

Y= -4.5
 
7.5/0.5=15

15*(-0.3)=  -4.5

-4.5/-0.3=15

Final answer:

To find the value of y when x = -0.3, substitute x = -0.3 into the equation and solve for y. The value of y is 3200.

Explanation:

To find the value of y when x = -0.3, we can use the given equation:

Y = 400+ 0.85(Y-0.25Y) + 300 + 200 +500 -0.1(Y-0.25Y)

Substituting x = -0.3 into the equation, we can solve for y.

Y = 400+ 0.85(Y-0.25Y) + 300 + 200 +500 -0.1(Y-0.25Y)
Y = 1400+ 0.6375Y - 0.075Y
0.4375Y = 1400
Y = 3200

Could some one please help with question 9b and 11

Answers

9b. a^4 +2a^2-8=0
factorise
(a^2 + 4)(a^2 - 2)=0
we then get two answers from the brackets
a^2=-4
a= sqrt(-4) or 2j
and the second bracket gives us a^2=2
a= sqrt(2)

11. First expand the brackets.
Ax^3 + Bx^2 - x^2 + Bx +Cx + D
then equate the coefficients, this basically means put all the x^3, x^2 etc values together.
so Ax^3=3x^3 so we know that A=3Then put the x^2 together, so Bx^2-x^2=-x^2 and rearranging this gives B=0
Next we do Bx+Cx = 2x and we know that B is 0 so we can get rid of it and know that C = 2.
finally we can see that D = -7

A box of candy weighs 340.23 grams and costs $18.99. if 1 gram is approximately 0.03527 ounces, what is the unit price per ounce of the candy?

Answers

340.23 / 0.03527 =9,646.44
$18.99 / 9,646.44 = .0019686
340.23 / 18.99 = 17.91
17.91 x .0019686 = .0352576

A number increased by seven is 15

Answers

Answer:

The number is 8.

To solve this equation, we can set it up as follows:

Let x be the unknown number.

  • The equation "A number increased by seven is 15" can be written as:

x + 7 = 15

  • Now, to find the value of x, we need to isolate it on one side of the equation. We can do this by subtracting 7 from both sides of the equation:

x + 7 - 7 = 15 - 7

  • On the left side, the +7 and -7 cancel out, leaving us with just x:

x = 15 - 7

  • Now, simplify the right side of the equation:

x = 8

So, the unknown number is 8.

To write the expression, I'll follow these steps :

↠ First, I am going to choose a letter that will represent my number.

↠ Then I'll plug it into the expression, and write the rest.

STEP ONE

  I'll choose d for my number.

STEP TWO

 We now have : d increased by 7 is 15, which is the same thing as d + 7 = 15.

To find d, subtract 7 from both sides :

d = 15 - 7 = 8

Therefore, d = 8.
