What is Proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Sarah used 10 gallons of gasoline to drive 240 miles.
let in 324 miles, x gallons of Gasoline is used.
Now, using proportion we have
10 / 240 = x / 324
3240 = 240 x
x = 3240 / 240
x = 324 / 24
x = 13.5 miles

Which expression makes the equation true for all values of x?
16x - 16 = 4( ? )
A 4x - 4
B 4x - 16
C 2x - 2
D 12x - 12
Answer:
A since if we multiply 4 × 4x, we get 16x, and 4 × 4, we get 16, which cancels with the other 16x - 16 on the left side. That makes sure that any x we choose will cancel out in the end.
Step-by-step explanation:
1. 16x - 16 = 4(4x-4)
2. 16x - 16 = 16x - 16

What is the surface area of this triangular pyramid?
Answer:
here you go
Step-by-step explanation:
To find the slant height of triangular faces: The slant height of a triangular pyramid is generally represented by 's'. Add all the areas together. Thus, the surface area of a triangular pyramid formula is 1⁄2(a × b) + 3⁄2(b × s) in squared units.
The surface area of this triangular pyramid is 10.908 in².
We have,
Base of Triangle= 3 in
Height of Triangle= 3 inch
P = 3 inch
h = 4 inch
Now, slant height= √4² + 1.5² = √16+2.25 = 4.272 inch
So, the Surface Area of Triangular Pyramid
= base Area + 1/2 x 3 x 4.272
= 1/2 x 3 x 3 + 6.408
= 4.5 + 6.408
= 10.908 in²
Thus, the surface area of this triangular pyramid is 10.908 in².

Step-by-step explanation:
.8x = 120.00
.87x = 112.00
This represents an easier way to do the problem if there is 20% off that means you are paying 80% of the original cost. You are paying 87% if it is 13% off.
To find the price at nine-irons divide 112 by .87
20% of 120 is 24
120 - 24 = 96
96 - 8 = 88
13% of 100 is 13
100 - 13 = 87

Laura went to a golf shop that has a golf simulator. The simulator estimates the distance that each ball she hits would have gone. She hit five balls each with her 2, 3, 4, 5, 6, 7, 8, and 9 irons. The distances of her golf shots are given in the table. Keep this table window open as you work on the tasks in this activity.
When Laura graphed the data, she got this scatter plot and drew a line of best fit. Keep the scatter plot window open as you work on the tasks in this activity.
When her brother graphed the data, he got a different scatter plot and drew a line of best fit. Keep the scatter plot window open as you work on the tasks in this activity.
Part A
Whose scatter plot matches the data, and what is wrong with the incorrect scatter plot?
Part B
Using the correct graph, describe the association shown
Part C
What is the slope of the line in the correct graph? What is the slope of the line in the incorrect graph? Are the slopes the same or different?
Part D
What is the y-intercept of the correct graph? What is the y-intercept of the incorrect graph? Are the y-intercepts the same?
Part E
If Laura were able to find a 0 iron, about how far could she hit it?
Part F
About what is the average change in distance for each increase of 1 in the iron number? What does this mean in terms of the situation?
Answer:
I can only help you with Part C and E as these two are the ones I am able to answer.
Part C: slopes are not the same
Part E: 195 yards
Step-by-step explanation:
Part C:
Part E: The slope of the line follows a linear pattern; therefore, find the equation for the line by calculating the slope and plugging in a point.
Slope:
y2-y1/x2-x1; (9, 105) (8,115)
(115-105)/(8-9) = -10; the slope is -10, now solve for the equation of the line.
y=mx+b; plug in the point (9,105)
105 = -10(9) +b
105 = -90 +b, add 90 to both sides
195 = b; rewrite the equation;
y=-10x+195; x stands for the iron, plug in 0 for x;
y=-10(0)+195
y=195 yards.
Answer:
A The scatter plot that matched the data is the second scatter plot while the first scatter plot wrongly represents the data because values of the Iron not present in the data is also represented in the scatter plot and also some values present in the data table is also missing in the First scatter plot.
B The scatter plot describes the strong negative association because in the scatter plot strong downhill linear relationship.
C In mathematics the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is denoted by the letter m in the equation of a straight line "y = mx + c".
D 195 yards

On a certain hot summer's day,432 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled 664.50How many children and how many adults swam at the public pool that day?
Answer:
399 children, 33 adults
Step-by-step explanation:
Children = c
Adults = a
c + a = 432
a = 432 - c
1.5c + 2a = 664.50
1.5c + 864 - 2c = 664.50
-.5c + 864 = 664.50
-.5c = -199.5
.5c = 199.5
c = 399
432 - 399 = 33
a = 33
Answer:
kids = 399
adults = 33

Answer:
x = 25º, right scalene triangle
Step-by-step explanation:
The interior angles of a triangle add up to 180º.
The red square indicates the angle measure is 90º.
We are left with two other angles, x and (2x + 15).
Let's set up an equation to represent the angle measures
90 + x + (2x + 15) = 180
First, combine like terms.
90 + x + 2x + 15 = 180
105 + 3x = 180
Subtract 105 from both sides to isolate x.
3x = 75
Divide both sides by 3 to further isolate x.
x = 25º
Let's check our answer by plugging it back into our original equation.
90 + x + (2x + 15) = 180
90 + 25 + (2(25) + 15) = 180
Simplify.
90 + 25 + (50 + 15) = 180
90 + 25 + 65 = 180
115 + 65 = 180
180 = 180
Your answer is correct.
x = 25º
Now we need to classify the triangle.
As stated before, the red square indicates the angle measure is 90º. This means our triangle is a right triangle.
Because the other two angle measures are different from one another, we know that the side measures cannot be equal. This leaves us with a scalene triangle.
Your answer is: right scalene triangle
Hope this helps!
