When you see two triangles, you can guess we’re going to deal with proportions. I’m going to set up a proportion between the long side of the big triangle and the long side of the little triangle
15/7
Ok...we’re making progress. We can make another proportion with height h and the “height” of the big triangle, 9
9/h
Since both of these are proportions, we can set them equal to each other
(9/h) = (15/7)
Cross multiply...
63 = 15h
h = 4.2 ft

A fair charged $2.50 admission for adults and a dollar for children. The receipts for 1 day were $1951 on 1300 paid admissions. How many adults attended the fair that day?
Answers
y = children
x + y = 1300
2.5x + y = 1951 Subtract these two equations.
-1.5x = - 651
x = -651/-1.5
x = 434 Adults
y = 1300 - x
y = 1300 - 434
y = 866 children
1300 x 1 = $1300
Extra collection:
1951 - 1300 = $651
Difference in price = $2.50 - $1.00 = $1.50
$651 ÷ 1.5 = 434 adults
1300 - 434 = 866 children
Ans: 434 adults and 866 children

(2 1/2)/(5/8)
Now, if you remember, when dividing with fractions, you may multiply with the reciprocal of the fraction that’s dividing. What that means is, if you flip the bottom fraction from (5/8) to (8/5), you make your life easier by multiplying.
(2 1/2) • (8/5)
To make things even easier, let’s turn 2 1/2 into an improper fraction. This turns it into (5/2). So...
(5/2) • (8/5)
If you remember, to multiply fractions, you multiply both numerators, then both denominators.
(5 • 8)/(2 •5)

A Ford is traveling 20 mph slower than a Buick. The Buick is traveling at a rate of 65 mph. Let F = the the speed of the Ford. Which formula below would correctly calculate the speed of the Ford?
Answers
Since the Ford is 20 mph slower than the Buick, all you have to do is subtract 20 from the speed of the Buick. We know the speed of the Buick, it is 65.
Therefore, the speed of the Buick is 65 - 20 or 45 mph.
If your starting salary is $50,000 and you receive a 4% increase at the end of every year, what is the total amount, in dollars, you will earn over the first 16 years that you work?
Answers
50000(1 + 1.04 + 1.04^2 + 1.04^3 + .... + 1.04^15) = 50000 * (1.04^16 - 1) / (1.04 - 1) = 1,091,226.56

Use benchmarks to choose the customary unit you would use to measure each height of a computer with a fit length of a semi truck the amount of liquid a bathtub holds.
Answers
For the height of a computer, it would be best to use inches. Most screens would be about 10 -15 inches.
For the length of a semi-truck, we could use feet or yards. Inches would be too small and miles would be way too long.
For the amount of liquid in a bathtub, we should use gallons.
Final answer:
Choose the best units of measurement for a variety of items based on benchmarks and size considerations.
Explanation:
When considering the size of a bathtub, the best unit for measuring capacity would be liters.
To choose the best unit of measurement for each item:
The volume of a water balloon: Milliliters
The length of a basketball court: Yards
The weight of an apple: Ounces or grams
The volume of a milk carton: Cubic centimeters
For the height of a light switch, the appropriate unit would be inches.
For the width of a refrigerator, the appropriate unit would be feet.

Suppose a bay window is a perfect semicircle with an area of 4.5 square feet. If the architect wants to use a scale of 0.5 inch = 1 ft on the floor plan, what is the radius of the bay window on the floor plan?
A) 0.85 inches
B) 1.7 inches
C) 3 inches
D) 3.4 inches
Answers
The answer is A) .85 inches
Step-by-step explanation:
A =
1 /2 πr2 4.5 = 1 2 πr2 1.6926 = r
thus, 0.50 in
1 ft = x in 1.6926 ft x = 0.8463
Final answer:
To find the radius of the bay window on the floor plan, calculate the radius of the actual bay window first, apply the scale factor, resulting in a radius of 3.4 inches that is option D is correct.
Explanation:
To find the radius of the bay window on the floor plan, you need to calculate the radius of the actual bay window first. Given the area of the bay window as 4.5 square feet in a semicircle shape, you can use the formula for the area of a semicircle, A = 1/2 * π * r².
Once you find the actual radius, you can then convert it to the scale of 0.5 inch = 1 ft to determine the radius on the floor plan. Remember, the scale factor is the ratio of a length on the drawing to the actual length it represents.
After the calculation, the radius of the bay window on the floor plan is 3.4 inches (Option D).
A school baseball team earned $3416.90 from selling 5716 tickets to their game. If grandstand tickets sold for 65 cents each and bleacher tickets sold for 40 cents each, how many of the bleacher tickets were sold?
Answers
Let x and y represent the number of grandstand and bleacher tickets sold respectively.
We know that the total number of tickets sold is 5716. Therefore, we will get the equation:
x+y = 5716
Therefore, x=5716-y.............................(Equation 1)
Now, we also know that the total value of tickets sold is $3416.90 or 341690 Cents.
We also know that the price of one grandstand ticket is 65 Cents. Thus, the price of x grandstand tickets will be 65x cents.
Likewise, since the price of one bleacher ticket is 40 cents, the price of y bleacher tickets will be 40y cents.
The information presented above gives us:
65x+40y=341690..........................(Equation 2)
Substituting x from (Equation 1) to (Equation 2) we get:
[tex] 65(5716-y)+40y=341690 [/tex]
Let us solve the above equation for y.
[tex] 65\times 5716-65y+40y=341690 [/tex]
[tex] 371540-25y=341690 [/tex]
[tex] \therefore 25y=371540-341690=29850 [/tex]
[tex] y=1194 [/tex]
Therefore, the total number of bleacher tickets sold was 1194.

Chris needs 3 1/2 cups of flour. His only clean measuring cup holds 1/3 cup. how many 1/3 cups of flour does Chris need?
Answers
To find the number of 1/3 cups of flour Chris needs, we need to divide the total amount of flour needed by the amount that can be measured with the 1/3 cup measuring cup. In this case, Chris needs 28 1/2 cups of flour.
Explanation:To find the number of 1/3 cups of flour Chris needs, we need to divide the total amount of flour needed (3 1/2 cups) by the amount that can be measured with the 1/3 cup measuring cup.
To do this, we convert the whole number 3 to thirds by multiplying by 3, which gives us 9 thirds. Then we add the 1/2 cup, which is equivalent to 3/6 or 6/12. So, the total amount in thirds is 9 + 6/12 = 9 1/2 thirds.
Now, we divide the total number of thirds by the number of thirds in one 1/3 cup.
9 1/2 thirds ÷ 1/3 third/cup = (9 1/2) ÷ (1/3) = (19/2) ÷ (1/3) = 19/2 × 3/1 = 19/2 × 3/1 = 57/2 = 28 1/2 cups.

AC = 4x+17
= 4*6 + 17
= 24 +17
= 41°
Answer:
The measure of AC is 41°
Step-by-step explanation:
Given : ∠ABC = (4x-3.5)°
Arc AC = (4x+17)°
An inscribed angle: An angle with its vertex on the circle and whose sides are chords.
The intercepted arc : The arc that is inside the inscribed angle and whose endpoints are on the angle.
The Inscribed Angle Theorem : The measure of an inscribed angle is half the measure of its intercepted arc.
Uisng the theorem
[tex]\angle{ABC}=\frac{1}{2} \text{arc(AC)}[/tex]
[tex](4x-3.5)^{\circ}=\frac{1}{2} (4x+17)^{\circ}[/tex]
[tex]2*(4x-3.5)^{\circ}= (4x+17)^{\circ}[/tex]
[tex]8x-7= 4x+17[/tex]
[tex]4x=24[/tex]
[tex]x=\frac{24}{4}[/tex]
[tex]x=6[/tex]
So, Arc AC = (4x+17)° = (4*6+17)° = (24+17)° = 41°
Hence the measure of AC is 41°

The top and bottom areas of the base cuboid are (10 in)*(10 in) = 100 in^2, for a total of 2*100 in^2 = 200 in^2.
The lateral area of the base cuboid is its perimeter (4*10 in = 40 in) multiplied by its height (2 in), so is 80 in^2.
Likewise, the lateral area of the "tower" is the product of its perimeter (4*5 in = 20 in) and its height (8 in), so is 160 in^2.
The sum of all these is 200 in^2 +80 in^2 +160 in^2 = 440 in^2.
The 3rd selection is appropriate.

Graph the system of equations. {2x−y=4x−y=−2 Use the Line tool to graph the lines.
Answers
Hear hear! For I have brought you the correct answer... (I took a "snip" of it so you can't see the entire graph but you can see the whole answer.)
By plotting the lines 2x - y = 4 and x - y = -2 using a graphing tool or on graph paper.
To graph these lines, you can start by rearranging them into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
For 2x - y = 4:
-y = -2x + 4
y = 2x - 4
This equation has a slope of 2 and a y-intercept of -4.
For x - y = -2:
-y = -x - 2
y = x + 2
This equation has a slope of 1 and a y-intercept of 2.
Now, you can graph these lines on a coordinate plane by plotting the y-intercepts and using the slopes to find additional points.
Once you have the two lines graphed, their point of intersection represents the solution to the system of equations.
