Quick help!!Also number 17!
Answer:
16. 29 and 30
17. C. 30 D. 31
Step-by-step explanation:
16. Given the inequality c ≤ $30, which is used to represent the situation, it implies that possible value of c must be equal to $30 or less than $30.
Two possible solutions form the options given would be:
29 and 30.
29 is less than 30, and 30 is equal to 30.
17. The inequality given is b ≥ 30.
This implies that possible solutions will be equal to 30 or greater than 30. It cannot be less than 30.
The solutions that apply would be:
30 (this is equal to 30) and 31 (this is greater than 30).
The remaining options don't satisfy or make the inequality statement true.

The weekly production cost C of manufacturing x watches is given by the formula C = 6000 + 3x, where the variable C is in dollars.
" (a) What is the cost of producing 1000 watches?
Answer:
therefore, to produce 1000 watches , it would cost 9000 dollars.
Price : 9 dollars a watch
Step-by-step explanation:
C=6000 + 3x
what is the cost of producing 1000 watches?
first do this
C= (1000)= 6000 + 3(1000)
C= (1000)= 6000 +3000
C= 9000

A field of grass feeds 28 cows for 6 days. How many days would the same field feed 21 cows?
Answer:
Step-by-step explanation:
28 cows × 6 days = 168 cow-days
(168 cow-days)/(21 cows) = 8 days
If a field of grass feeds 28 cows for 6 days, the number of days that the same field would feed 21 cows is 8 days.
How to calculate number of days?This question involves the use of inverse proportion to solve.
According to this question, a field of grass feeds 28 cows for 6 days. The number of days it would take 21 cows is calculated as follows:
28 cows is fed for 6 days
21 cows will be fed for (28 × 6) ÷ 21 = 8 days.
Therefore, If a field of grass feeds 28 cows for 6 days, the number of days that the same field would feed 21 cows is 8 days.

What is the area of the fire pit? (Use 3.14 for pi.)
Answer:
[tex]Area = 65.94[/tex]
Step-by-step explanation:
I will assume that the shaded region is the fire pit
Given
[tex]R = 5[/tex]
[tex]r = 2[/tex]
Required
Determine the area of the fire pit
First, calculate the area of the big circle.
[tex]A_2 = \pi R^2[/tex]
Area of the small is:
[tex]A_1 = \pi r^2[/tex]
The area of the pit is:
[tex]Area = A_2 - A_1[/tex]
[tex]Area = \pi R^2 - \pi r^2[/tex]
[tex]Area = \pi (R^2 - r^2)[/tex]
[tex]Area = 3.14 (5^2 - 2^2)[/tex]
[tex]Area = 3.14 (25 - 4)[/tex]
[tex]Area = 3.14 * 21[/tex]
[tex]Area = 65.94[/tex]

Which system of equations could be used to find the number of tickets sold before the tournament, x, and the number of tickets sold at the door, y? Remember, 743 tickets were sold, and 75 more tickets were purchased before the tournament than at the door.
Select the correct system based on the scenario.
y = x + 75
y = 75x + 743
y = x + 75
y = x + 743
x + y = 743
x – y = 75
x + y = 743
y – x = 75

the sum of two numbers is 51 and the difference is 13. what are the numbers
Answer:
Step-by-step explanation:
19 and 32
Answer:
the two numbers are 19 and 32
Step-by-step explanation:
let's call the numbers x and y.
write out the equations
x + y = 51
x - y = 13
simplify the second equation
x = 13 + y
substitute into the first equation and simplify
(13 + y) + y = 51
13 + 2y = 51
2y = 51 - 13
2y = 38
y = 19
substitute y for 19 in the second equation
x = 13 + y
x = 13 + 19
x = 32

Matthew and his 3 siblings are weeding a flower bed with an area of 9 square yards. if they share the job equally, how many square yards of the flower bed will each child need to weed? use a tape diagram to show your thinking
Answer:
2.25 sq yards for each child
Step-by-step explanation:
Uhh, I can't really use a diagram.
Matthew is also one person, so instead of dividing 9 by 3, we would be dividing 9 by 4.

In the rectangle below what is X?
Answer:
X= 82°
Step-by-step explanation:
Since we know ∠DAB is 41°, we also know that ∠CBA is 41°, since they must be equal. This tells us that the bottom angle of that triangle must be 98°, since the sum of all interior angles must equal 180°. Since this angle is supplementary to x, we know that x must equal 82°.
