hey hey. i’ll help you. sorry if this is long. :)
okay so let’s think about this. there’s a lot of extra information that we don’t need so let’s get rid of everything up to ”7 years”.
now.. she works 40 hours per week right? and she makes $2.13 per hour. so now that we have that, let’s think what 40 x $2.13 is. if you do the math right you should get 85.2 or $85.20. so that’s in one week, but then in a typical week sheserves 75 tables that have an average bill of $4q. so now that we have those numbers, we take 41 x 75 then add it to our weekly number. so we multiply the two together and we get 3075. not 30.75 but $3075.00! so take that and add it to 85.20.. you should get 3160.2, or $3160.20. but then typically an 18% tip, so let’s go back to the number before (41) and find what 18% of 41 is.
18% of 41 is 7.38 or in this case, $7.38. so once we have that, you’re gonna want to multiply 7.38 by 75 to get that total. if you do that you should get 553.5
okay.. now we have all the numbers we need. we’re already basically done, we just need to add the tips to the other total!
$3160.20 + $553.50 = $3713.70
so in a week, she makes $3713.70
i hope this helped you! good luck!

Work out the size of angle x.
Not drawn accurately
132°
X Х
54°
Answer:
x = 84
Step-by-step explanation:
The sum of the angles around a point = 360°
sum the given angles and equate to 360
x + 132 + 54 + 90 = 360
x + 276 = 360 ( subtract 276 from both sides )
x = 84
Answer:
x = 84°
Step-by-step explanation:
→ Recall the fact that angles around a point add up to 360°
360 - (90 + 54 + 132 ) = x
→ Simplify
360 - 276 = x
→ Simplify again
84 = x ∴ x = 84°

A pet store owner, Byron, needs to determine how much food he needs to feed the animals. Byron knows that he needs to order the same amount of bird food as hamster food. He needs four times as much dog food as bird food and needs half the amount of cat food as dog food. If Byron orders 600 packages of animal food, how much dog food does he buy? Let b represent the number of packages of bird food Byron purchased for the pet store.
Answer:
300 bags of dog food
Step-by-step explanation:
4b + 2b + b + b = 600
(dog) + (cat) + (bird) + (hamster) = 600
8b = 600
b = 75
Byron purchased 75 bags of bird food. He needs 4 times that of dog food. So, he purchased 300 bags of dog food.

Miguel is ordering 6 bags of cat food from Canada. Each bag has a mass of 7.5 kg. To determine the shipping costs, Miguel needs to know the total weight in pounds. What is the weight of the cat food in pounds? Use 1 kg = 2.2 lbs and do not round any computations.
Answer:
99 pounds
Step-by-step explanation:
7.5×6=45kg
1kg=2.2lb and we have 45kg because this is direct proportion what you do to one side you havbe to do to the other
so 2.2lb×45 gives you 99 pounds

After 14 years, I shall be three times as old as I was 4 years ago. What is my present age?
Answer:
Present age = 13 years
Step-by-step explanation:
Let the present age be x years.
14 years after age = (x + 14) years
4 years ago age = (x - 4)
According to the given information:
14 years after age = 3 times 4 years ago age
x + 14 = 3(x - 4)
x + 14 = 3x - 12
14 + 12 = 3x - x
26 = 2x
x = 26/2
x = 13 years
Thus, the present age is 13 years

Noah and Lin are making paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
height (h)=
radius (r)=
Answer:
So, The possible values of h and r are
1. r = 3 , h = 3
2. r = 1, h = 27
3. r = 2, h = 6.75
Step-by-step explanation:
P.S - The exact ques is -
As we know that Volume of cone , V = [tex]\frac{1}{3}\pi r^{2}h[/tex]
As given,
V = [tex]9\pi[/tex]
⇒[tex]\frac{1}{3}\pi r^{2}h = 9\pi \\ \frac{1}{3} r^{2}h = 9 \\r^{2}h = 27[/tex]
So,
The possible values of h and r are
1. r = 3 , h = 3
2. r = 1, h = 27
3. r = 2, h = 6.75
In Case I-
When r = 3, h = 3
(3)² ×3 = 9×3 = 27
Satisfied
Case II-
r = 1, h = 27
(1)²×27 = 1×27 = 27
Satisfied
Case III-
r = 2, h = 6.75
(2)²×6.75 = 4×6.75 = 27
Satisfied
If the radius of the base of the cone is 2 inches then the height of the cone should be 2.1485 inches.
What is the volume of the cone?The volume of the cone is the volume occupied by the cone. It is given by the formula,
[tex]\text{Volume of the cone}= \dfrac{1}{3} \pi r^2h[/tex]
where r is the radius of the base, and h is the height of the cone.
Now, as it is given that cones need to hold 9 cubic inches of popcorn. therefore, the volume of the cone can be written as,
[tex]\text{Volume of the cone}= \dfrac{1}{3} \pi r^2h\\\\9 \times 3 = \pi r^2h\\\\\dfrac{9 \times 3}{\pi}=r^2 h\\\\8.5943 = r^2 h[/tex]
Thus, the product of the square of the radius and the height of the cone should be such that the result is 8.5943.
Now, let the radius of the cone be 2 inches, therefore, the height of the cone is,
[tex]8.5943 = r^2 h\\\\8.5943 = (2^2) h\\\\h = 2.1485\rm\ in[/tex]
Hence, if the radius of the base of the cone is 2 inches then the height of the cone should be 2.1485 inches.

Two groups are hiking at about the same speed . Mario’s group hikes for 2.5 hours Seemas group hikes for 4.7 hours and covers 8.8 more miles . How fast are the kickers going ? Solve the equation below to find out . 4.7x=2.5x+8.8
Answer: 18.8 miles
Step-by-step explanation:
Ww are given the equation 4.7x=2.5x+8.8 to solve the question. This will be:
4.7x = 2.5x + 8.8
Collect like terms.
4.7x - 2.5x = 8.8
2.2x.= 8.8
x = 8.8/2.2
x = 4
To know how fast the kickers are going will be
4.7x = 4.7 × 4 = 18.8 miles
Solve the system by substitution.
y = 8x
y = 4x + 8
Answer:
y = 16
x = 2
Step-by-step explanation:
y = 8x
y = 4x + 8
then, by substitution:
8x = 4x + 8
8x - 4x = 8
4x = 8
x = 8/4
x = 2
y = 8x
y = 8*2
y = 16
Check:
y = 4x + 8
y = 4*2 + 8
16 = 8 + 8
Your grandmother has given you a gift of $1500 for your birthday. You are thinking about your future and
considering two different options on how to manage your money. Option A: You take all of your $1500 and
deposit it into a savings account that has a 5% interest rate per year. Option B: You spend $500 on a new
Apple Watch and deposit the remaining $1000 in a savings account that has a 5.5% interest rate per year.
.
Which account would have the most in 10 years? 20 years? Mathematically, explain your reasoning.
Which option would you choose and why?
.
Answer:
B
Step-by-step explanation:
if you put the rest of your money in a savings account you can use that money for your college fund or maybe buy a car ect.
Answer:
OPTION A yields the most money at 10 and 20 years. Hence Option A is the better choice for "thinking about your future"
Step-by-step explanation:
In the absence of any more information, I am going to assume that Simple Interest applies. (see attached)
hence the applicable formula is:
A = P(1+rt), where
A = final amount after t years
P = Principal (beginning) amount ($1500 for option A and $1000 for option B)
r = annual interest rate (5% = 0.05 for option A and 5.5% = 0.055 for option B)
t = time (we are asked to evaluate t = 10 years and t = 20 years)
For option A :
P = $1500 and r = 5% = 0.05
A = P(1+rt)
A = 1500 [ 1 + (0.05)t]
at 10 years: A = 1500 [ 1 + (0.05)(10)] = $2,250
at 20 years: A = 1500 [ 1 + (0.05)(20)] =$3,000
For option B :
P = $1000 and r = 5.5% = 0.055
A = P(1+rt)
A = 1000 [ 1 + (0.055)t]
at 10 years: A = 1000 [ 1 + (0.055)(10)] = $1,550
at 20 years: A = 1000 [ 1 + (0.055)(20)] = $2,100
Comparing all the 4 results above, we can see that OPTION A yields the most money at 10 and 20 years. Hence Option A is the better choice for long term returns.
