Answer:
To find this, you must find the total number of points Sara has scored already. She has answered 10 multiple choice questions which are 4 points each. This means that Sara has scored 40 points so far.
If Sara wants to score at least 70 points, she needs to score at least 30 more points. To find how many open-ended questions she needs to answer, you need to divide the remaining number of points by the number of points an open-ended question is worth. The number we get will be x.
30/5 = 6
This means Sara must complete at least 6 open-ended questions to score 70. Now, all we have to do is figure out which inequality sign to use. Since Sara wants to score more than 70 points, it should be the "greater than" sign.
Your answer is: x>6

Perimeter = first you need to add 2 and 2 to get the bottom, then you add 2 and 1 to get the side to the left. after that, it's fairly easy. you just add all. The answer should be 14in.
Area of figure = It would be easier to split it then add them. You would need to time 2 by 2 which you should get 4. Then, you would need the length for the bottom, so first, you will need to add 2 and 2 which you get 4 then times that by 1 which should be 2. Add them together and the answer should be 6in.
Figure 2Perimeter = first you need to find the triangle. It said the circle is 3cm. so that means you just got to add 4, 5, and 3 together to get the perimeter of the triangle. Then, for the half-circle, 2[tex]\pi[/tex]3. This should give you 18.85. Then add them together to get 30.85cm.
Area of figure = It would be easier to split it then add them. You would need to figure out what the formula for a triangle is which is [tex]H_{b} B[/tex]/2. This should give you 6. Then you got to figure out the area of the circle, which is [tex]\pi 3^{2}[/tex] which should give you 28.27. then you add them together, which gives you 34.27cm.
I hope this helped you out.

A store manager can spend at most $1,000 a day for operating costs and payroll. It costs $100 each day to operate the store and $30 dollars a day for each employee. Use the following inequality to determine how many employees the manager can afford for the day, at most:
30x + 100 ≤ 1000
Answer:
x = 30 employees.
Step-by-step explanation:
30x + 100 = 1000
- 100 - 100
30x = 900
900/30 = 30

The graph below shows the price, y, in dollars, of different amounts of granola, x, in pounds:
A graph titled Granola Prices shows the Number of Pounds on the x-axis and Price in dollars on the y-axis. The scale on the x-axis shows numbers from 0 to 12 at increments of 2, and the scale on the y axis shows numbers from 0 to 48 at increments of 8. A straight line joins the ordered pairs 0, 0, and 12, 48
Which equation best represents the relationship between x and y?
y = 8x
y = x + 4
y = 4x
y = x + 8

Which of these lines has a positive slope?
A. a
B. b
C. c
D. there is not enough information to tell
Answer:
C. c
as the y axis increases with increase in x axis
a: has a negative slope
b: does not have a specific slope
Answer:
C.c
Step-by-step explanation:
the slope of line b is zero because it's parallel to x-axis.
the slope of line c is positive because it makes a angle smaller than 90° with x-axis.
and finally the slope of line a is negative because it makes a angle greater than 90° with x-axis.

Can somebody please help me with questions 9 and 10, please
please help the question is below :)))
Answer:
-1-(-6) = 5
8-(-5) = 13
Step-by-step explanation:
So for the first one -1-(-6), when you have two negatives next to each other then it turns into a plus. So when it turns into a plus we will have -1+6 now although there is a plus sign we are not gonna add because our two numbers have different signs so we are gonna subtract and take the sign of our bigger number and here our bigger number is 6 so our answer will be positive and 6-1=5. So the answer is 5.
Now for the second one 8-(-5), the same thing when you have two negatives next to each other then it turns into a plus. So, when it turns into a plus we will have 8+5. And here they both have the same signs so we are gonna add and 8+5=13. So the answer is 13.
**When I say signs I mean it is either positive or negative, also a positive number if it is at the beginning of the equation then it most likely will not have the plus sign before it.**

Total number of observations = 9[tex] \sf \rightarrowtail \: mean = \frac{73 + 68 + 73 + 85 + 92 + 81 + 88 + 35 + 48}{9} [/tex]
To make the calculation easier, first add the numbers that sum to multiples of 10

Mode ↯35, 48, 68, 73, 73, 81, 85, 88, 92
The most occurred number is 73 it has occurred 2 times. Hence, it is the mode!Step-1: Add the data set.
[tex]\bullet \ \ 73 + 68 + 73 + 85 + 92 + 81 + 88 + 35 + 48[/tex]
[tex]\bullet \ \ 643[/tex]
Step-2: Divide the "added" data set by the total digits in the data set.
There are nine digits in the data set.
[tex]\bullet \ \ \frac{643}9}[/tex]
[tex]\bullet \ \ 71.44[/tex]
Thus, the mean of the data set is 71.44.
Solution (Finding the median of the data):Step-1: Arrange the data set in descending form.
Greatest => Smallest
[tex]\bullet \ \ 73, 68, 73, 85, 92, 81, 88, 35, 48[/tex]
[tex]\bullet \ \ 92, 88, 85, 81, 73, 73, 68, 48, 35[/tex]
Step-2: Count the number of digits in the data.
[tex]\bullet \ \ \tex\text{9 digits in total}[/tex]
Step-3: Revise the following.
[tex]\bullet \ \ \tex\text{If there are even number of digits:} \ \frac{\tex\text{(Number of digits)}}{2}[/tex]
[tex]\bullet \ \ \tex\text{If there are odd number of digits:} \ \frac{\tex\text{(Number of digits)} + 1}{2}[/tex]
Step-4: Odd or Even?
[tex]\bullet \ \ \tex\text{Even numbers:} \ 2, 4, 6, 8, 10...[/tex]
[tex]\bullet \ \ \tex\text{Odd numbers:} \ \ 1, 3, 5, 7, \bold{9}, 11...[/tex]
There is an odd number of digits.
Step-5: Use the formula.
[tex]\bullet \ \ \frac{\tex\text{(Number of digits)} + 1}{2}[/tex]
[tex]\bullet \ \ \frac{\tex\text{9} + 1}{2}[/tex]
[tex]\bullet \ \ \frac{\tex\text{10}}{2}[/tex]
[tex]\bullet \ \ 5[/tex]
The fifth digit in the data is the median.
Step-6: Revise the data set.
[tex]\bullet \ \ 92, 88, 85, 81, \bold{73}, 73, 68, 48, 35[/tex]
The median is 73.
Solution (Finding the mode of the data set:The most repeating number is the mode. Let's put the data set in a frequency table.
Step-1: Putting the data set in a frequency table:

Looking at the table, we can tell that 73 has repeated two times and has repeated the most.

Jerome is cooking dinner. He needs 8 ounces of broccoli for each person.
Part A: Jerome is not sure how many people will come to dinner. Write an expression with a variable that represents the amount of broccoli Jerome needs for dinner. Identify what the variable represents.
Part B: If Jerome has 32 ounces of broccoli, how many people can he feed? Create an equation and show all work to solve it.
Answer:
Part A: 8Bp (8 b(broccoli) times p(people)
If Jerome has 32 ounces of broccoli then he can feed 4 people
32 pieces of broccoli divided by the 8 piece of brocoli per person will tell you that he will have 4 pieces of broccoli
Answer:
Part A
lets just say 5 people come for dinner so 5x8 = 40 so he will need 40 ounces of broccoli
Part B so 8 ounces per person and he has 32 ounces so he will have feed 4 people
