mary bought five pairs of socks that cost $8 each. if the tax rate was 8% how much did mary pay in total?
(please help!!)
Answer:
The Answer would be $40.64
Step-by-step explanation:
To find a percentage of a certain number, you must multiply that number by the percentage in decimal form. Since the socks cost 8 dollars each 8 x 0.08 = 0.64 Meaning the tax cost is 64 cents. 8 x 5 = 40 Giving us $40.64

Find the x-intercept(s) and the coordinates of the vertex for the parabola y=x + 2x-15. If there is more than one x-intercept, separate them with commas,
Step-by-step explanation:
y = x^2 + 2x - 15
To find the x-intercepts, factor out the right side:
y = x^2 + 2x - 15
= (x + 5)(x - 3)
This means that the x-intercepts are at (-5, 0) and (3, 0).
Method 1:
The x-coordinate of the vertex of a parabola is given by the following:
x = -b/2a, where a = 1 and b = 2
= -(2/(2×1))
= -1
Using this value of x gives y = -16
Therefore, the coordinates of the vertex is (-1, -16).
Method 2:
We can find the x-coordinate of the vertex by taking the derivative of y and equating it to zero:
y' = 2x + 2 = 0 ---> x = -1
Using this value of x into our equation, we get y = -16.
Therefore,
vertex: (-1, -16)

Jessica's parents are always telling her to turn off the lights when she leaves her room. The fixture in Jessica's room requires four bulbs that each use 75 watts of
electricity when they're on.
a. Jessica's parents estimate that she leaves the lights on unnecessarily for 2.5 hours per day. How many watt-hours of electricity are used by these bulbs during 2.5
hours?
b. Approximately how many kilowatt-hours of electricity are used in a year to keep these bulbs lit for 2.5 hours per day?
C. At a cost of $0.12 per kilowatt-hour, how much money is wasted per year by keeping these lights on unnecessarily? Round to the nearest dollar.
d. If five million people keep lights on as Jessica does, how much is wasted in unnecessary electric expenses?
Answer:
Step-by-step explanation:
4*75 = 300 watts ( her light)
a) 2.5*300=750 w/h
b) 365*750 = 273.75 Kw/h
c) (0.12)*273.75 = $32.85
d) 32.85 * 5,000,000 = $164,250,000.00
Answer:
a.) 750
b.) 273.75
c.) $33.00

Javier made 180 cupcakes. Each cupcake is covered with frosting. • 1/3 of the cupcakes have vanilla frosting. • 1/10 of the cupcakes have lemon frosting. • 2/5 of the cupcakes have chocolate frosting. • the rest have strawberry frosting. How many cupcakes have strawberry frosting
Answer:
30 strawberry cupcakes
Step-by-step explanation:
180 cupcakes in total
1/3 of 180 - 60 = vanilla
1/10 of 180- 18 = lemon
2/5 of 180 - 72 = chocolate
rest of 180 - 180-(72+18+60) = strawberry
rest of 180 - 180-150 = 30 = strawberry
Add all of them:
60 vanilla
18 lemon
72 chocolate
30 strawberry
---------------------------
180 cupcakes

Ms. Garcia burns 236 calories riding her bike each
hour. She wants to burn more than 354 calories
riding her bike at the same rate.
Which inequality represents all possible values for
t, the number of hours Ms. Garcia must ride her
bike to burn more than 354 calories?
A t < 1.5
B t > 1.5
C t < 0.5
D t > 0.5
The inequality that represents all possible values for t is:
t > 1.5
Which inequality is the correct one?
We know that she burns 236 calories per hour, so if she rides for t hours, she burns a total of:
t*236 calories.
Now, she wants to burn more than 354, so we have the inequality:
t*237 > 354
Solving for t (by dividing both sides by 237) we get:
t > 354/237 = 1.5
t > 1.5
So the correct option is B.

Jose is trying to pick out an outfit for the first day of school. He can choose from 2 pairs of pants, 6 t-shirts, and 3 pairs of shoes. How many different outfits does Jose have to choose from?
Jose has to choose from 36 different ways.
What is the Combination?The various ways in which objects from a set may be selected, generally without replacement to form subsets is known as combination.
For the given situation,
Pairs of pants = [tex]2[/tex]
T-shirts = [tex]6[/tex]
Pairs of shoes = [tex]3[/tex]
The formula to find the number of ways using combination = [tex]nC_{r}[/tex]
Number of ways of picking the outfit = [tex](2C_{1}) (6C_{1}) (3C_{1} )[/tex]
⇒ [tex](2)(6)(3)[/tex]
⇒ [tex]36[/tex]
Hence we can conclude that Jose has to choose from 36 different ways.
