Step-by-step explanation: Normally you can
look for places where the graphed line crosses the grid. Count the number of vertical squares. This is the numerator. Count the number of squares horizontally. This is the Denominator.
In these examples, the scales on the graphs have different scales on the horizontal and vertical dimensions. So you have to choose numbers from the graph and calculate the rates of change.

Answer:
10.5 cm
Step-by-step explanation:
12÷9= 1.3 (1dp)
14÷(12÷9)= 10.5cm
Answer:
y = 10.5 cm
x = 80 degree
Step-by-step explanation:
Our approach is find measures first and y is our missing measure.
To find y
PQRS : ABCD is in ratio the same as CD : RS
We need to work out CD : RS to find measures of AD : SP
To find ratio we look at side measures first
CD : RS = 12 : 9
12/9 = 1.333333
So that AD : SP = 14 : ?
14 / 1.333333 = 10.50000
AD : SP = 14 : 10.5
y = 10.5 cm
To find x
We are given opposite angles and know with quadrilaterals they both share same opposite diagonal length ratios and share same opposite angles.
Where two angles are always in pairs given 100 degree can be multiplied by 2 and use the equation.
360 - (100 x 2) / 2 = (360 - 200) / 2 = 160/2 = 80 degree
x = 80 degree

Answer:
The area of the figure is equal to 156 m².
Step-by-step explanation:
=> (7 x 18) + (5 x (18 - 6 x 2)) =
=> 126 + (5 x (18 - 12)) =
=> 126 + (5 x 6) =
=> 126 + 30 = 156

Answer:
525
Step-by-step explanation:
If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525
What will be the result of substituting 2 for x in both expressions below?
1/2 x + 4
x + 6 - 1/2 x minus 2
Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.
Both expressions equal 6 when substituting 2 for x because the expressions are equivalent.
One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
One expression equals 6 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
Answer:pretty sure the answer is A
Step-by-step explanation:
1/2(2) + 4 = 1 + 4 = 5
2 + 6 - 1/2(2) -2 = 8 - 1 - 2 = 5

Andy wants to rent a boat and spend at most $66. The boat costs $7 per hour, and Andy has a discount coupon for $4 off. What are the possible numbers of hours Andy could rent the boat? Use for the number of hours. Write your answer as an inequality solved for.
Answer:
h ≤ 10
Step-by-step explanation:
Let's first consider the cost of renting the boat without the discount. If Andy rents the boat for h hours, he will have to pay:
Cost = (price * time)
Cost = 7h
With the $4 discount, the cost of renting the boat for h hours will be:
Cost = (price * time) - discount
Cost = 7h - 4 .
We want to find the possible values of h such that the total cost of renting the boat is at most $66, which means:
7h - 4 ≤ 66
Step 1: To solve for h, we will add 4 to both sides of the inequality:
7h ≤ 70
Step 2: Finally, we will divide both sides by 7 to isolate h:
h ≤ 10
Therefore, Andy can rent the boat for at most 10 hours with his budget of $66 and the $4 discount coupon.
In inequality form, the solution is:
0 < h <= 10
Optional Step 3: We can try plug in 9 for h, 10 for h, and 11 for h to see how the inequality works:
9 for h:
7(9) - 4 ≤ 66
63 - 4 ≤ 66
59 ≤ 66
Thus, normally, the price to boat for 9 hours without the discount is $63, but with the $4 discount its now $59. $59 is less than $66 and allows Andy to not exceed his limit.
10 for h:
7(10) - 4 ≤ 66
70 - 4 ≤ 66
66 ≤ 66
Thus, normally, the price to boat for 10 hours without the discount is $70, but with the $4 discount its now $66. $66 is equal to $66 and is maximum amount Andy can spend to not exceed his limit.
11 for h:
7(11) - 4 ≤ 66
77 - 4 ≤ 66
73 ≤ 66
73 > 66
Thus, normally, the price to boat for 11 hours without the discount is $77, but with the $4 discount its now $73. $73 is greater than to $66 and causes Andy to exceed his limit since 11 is greater than 10.

Answer:
1) Yes, table shows a probability distribution
2) Mean = 1.5
3) Standard Deviation = 1.1
Step-by-step explanation:
PART 1:
For the table to show a probability distribution, the sum of all probabilities should be equal to 1
Sum of probabilities = 0.358 + 0.443 + 0.174 + 0.025
Sum of probabilities = 1
Hence, the table shows the probability distribution.
PART 2:
The formula for mean is given by:
Mean = Sum of terms/ Total no. of terms
Mean = (0+1+2+3) / 4
Mean = 1.5
PART 3:
The formula for standard deviation is given by:
\(\sigma=\sqrt{\frac{\sum(x_i-\mu)^2}{N}}\)

Starting at 1:00 p.m., the temperature changes -4 degrees Fahrenheit per hour. Write an equation to find how many hours it will take to reach -1 *F.
Answer:
35 x (-4x) = -1 (9 hours)
Step-by-step explanation:
If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.
35 x (-4x) = -1
-4x = -36
x = 9
35 x (-4x) = -1 (9 hours)
Step-by-step explanation:
If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.
35 x (-4x) = -1
-4x = -36
x = 9
Parallel lines r and s are crossed by transversal t to form 8 angles. Clockwise from top left, the angles formed with line r are blank, blank, 1, (2 x + 12.8) degrees; with line s are blank, blank, 117.6 degrees, blank.
What is the value of x?
2x+12.8=117.6
We move all terms to the left:
2x+12.8-(117.6)=0
We add all the numbers together, and all the variables
2x-104.8=0
We move all terms containing x to the left, all other terms to the right
2x=104.8
x=104.8/2
x=52+0.8/2

Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2
A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day
