Answer:
28.50/3=r
Step-by-step explanation:
Answer:
28.50 divided by 3.
Step-by-step explanation:
This is because if 28.50 is the total and we know she worked for 3 hours that means that the answer to our equation: 9.5 means that each hour she worked for she was given 9.50 or 9.5 dollars. We can check this by doing 9.5 x 3 which gives us 28.5 or 28.50. :)

Answer:
24
Step-by-step explanation:
If we reschedule the doctor's half-hour break so that s/he quits work at 3:00 pm, s/he will have worked 6 straight hours from 9 am to 3 pm. Seeing 4 patients each hour, the doctor will have seen ...
(6 h) × (4 pt/h) = 24 pt
The doctor saw 24 patients by 3:30 pm.

I think
2,-6
5,y
so we add 3 to the 2 to make it to a 5
so i think we add the 3 to the -6 to make it to a -3
so i think the answer is -3

Vivian has a 550 page book on folk tales . If she reads 9 pages everyday before falling asleep . how many days will it take her to finish the book
Answer:
62 days
Step-by-step explanation:
Given that she reads 9 pages everyday before falling asleep. Then, on day one, she would read 9m pages.
On day 2, she would read another 9 pages, making 18 pages after 2 days. If she will finish the book in x days then
x = 550/9
=61 1/9 days
Converting the 1/9 into a day then, she will finish the book in 62 days, reading just a page on the 62nd day.

A combination lock has 7 digits. How many distinct combinations does this lock have if the numbers used have to be 0 through 5
Answer:
279,936
Step-by-step explanation:
Since there are 6 options for every digit, and seven digits
So,
6^7=279,936
The total number of distinct combinations for making 7 digits lock is 2,79,936.
What is permutation?A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
Formula for permutation with repetition:[tex]nP_{r} =n^{r}[/tex]
Where,
P is the total number of combinations.
n is the total number of items in a set
r is the total number of items to be selected from the set
According to the given question.
We have to form a lock that has 7 digits by using numbers from 0 to 5.
⇒ Total numbers of items in a set = 6
and total number of items to be selected = 7
Since, we have to form a lock of 7digits but we have only 6 digits. So we have to repeat this numbers so that we can form a 7 digit lock.
Therefore, the total number of combinations for making 7 digits lock is given by
[tex]6P_{7} = 6^{7}[/tex]
⇒[tex]6^{7}=2,79,936[/tex]
Hence, the total number of distinct combinations for making 7 digits lock is 2,79,936.

Martin ordered a pizza with a 12-inch diameter. Ricky ordered a pizza with a 16-inch diameter. What is the approximate difference in area of the two pizzas in
square inches?
OA. 4
OB. 16
O C. 112
O D. 352
Answer:
88 in²
Step-by-step explanation:
The shape of a pizza = Circular
Area of a circle = πr²
For Martin
Martin ordered a pizza with a 12-inch diameter.
Radius = Diameter/2 = 12 inch/2 = 6 inch
Area of Martin's pizza = π × 6²
= 113.09733553 in²
≈ 113.1 in²
For Ricky
Ricky ordered a pizza with a 16-inch diameter.
Radius = Diameter/2 = 16 inch/2 = 8 inch
Area of Martin's pizza = π × 8²
= 201.06192983in²
= 201.1in²
The approximate difference in area of the two pizzas in square inches is calculated as:
201.1 in² - 113.1 in²
= 88 in²

I need help!!! I’ll mark you brainliest
This is timed!!
Answer:
Using the inverse composition rule you know that if (fog)=x and (gof)=x then the functions are inverses.
( g o f ) = ( 7 x + 1 ) − 1 7 this will result in (gof)=x ( f o g) = 7 x − 1 7 +1 = x − 1 + 1 =x
graphically you can check this if it seems that the functions are reflected over the line x=y.

How do I Factor 42p⁴+9p³q²-18p²q²
Answer:
42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)
Step-by-step explanation:
To answer this, we simply look for that term that is common to all
Looking at the given expression, we can see that the term we are looking for is p^2
Thus, we have that;
42p^4 + 9p^3q^2 -18p^2q^2 = p^2 (42p^2 + 9pq^2 - 18q^2)
When we multiply the term outside the bracket with each of the terms inside, we get back the original term
