inches? (Use 3.14 for 2.)
Answer:
the area is 1235
Step-by-step explanation:
Answer:
2714.33 sq in
explanation-
since circle is divided into 6 congruent sectors, area of each sector is 1/6th of area of circle.[tex]ar \: of \: sector \: = ar \: of \: circle \: \div 6 \\ = \pi \times 72 \times 72 \div 6 \\ = 2714.33[/tex]The family car runs out of gas. You have to push it up the driveway into a service station. The ramp is 4 meters long and rises 0.10 meters. The car weighs 9000 N. You push with a force of 300N. How efficient is the ramp?
Answer:
Step-by-step explanation:
slope, m = 0.1m/4m = 0.025
Theoretical effort (ignoring friction) = 9000N * 0.025 = 225 N
actual effort = 300 N
efficiency
= potential energy out / actual energy in
= 225 N / 300 N = 0.75

. Mr. Marcum bought 7 tickets to a puppet show and spent $40. He bought a combination of child tickets for $4 each and adult tickets for $10 each. How many of each ticket did he buy?
Answer:
Mr. Marcum bought 5 child tickets and 2 adult tickets.
Step-by-step explanation:
First, assume that Mr. Marcum bought either 7 tickets of child tickets or 7 tickets of adult tickets. I'm using 7 child tickets for this working.
If Mr. Marcum bought 7 child tickets,
total money spent = $4 * 7 = $28
This is not equal to $40 and there has to be more money spent.
We should also calculate the price difference between the adult ticket and the child ticket.
Price difference per ticket = $10 - $4 = $6
This means that if Mr. Marcum bought an adult instead of a child ticket, he would spend $6 more.
In this case, Mr. Marcum has to spend $40- $28 = $12 more.
Hence, the number of adult tickets replacing the child tickets is $12/$6 = 2.
The number of child tickets = 7 - 2 = 5

10. What value of I would make the quadrilateral a parallelogram? Round your answer to the nearest tenth. E F 17.x - 29 12r - 8 H 8x + 17 G AO I = 4.2 B. x= 5.1 CO x = 7.5 D.O x = 6.3
Answer:
A
Step-by-step explanation:
Math
===================================================
Work Shown:
If we want this figure to be a parallelogram, then the opposite sides EH and FG must be the same length.
Let's use that fact to solve for x.
EH = FG
17x-29 = 12x-8
17x-12x = -8+29
5x = 21
x = 21/5
x = 4.2; answer is choice A
------------
Extra info:
If x = 4.2, then,
EH = 17x-29 = 17*4.2-29 = 42.4FG = 12x-8 = 12*4.2-8 = 42.4Both EH and FG are 42.4 units long which helps confirm the answer.

The value of the unknown number is 5. The correct option is B.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that 3 is more than 3 times a number is equal to 12 less than 6 times the number.
The value of the unknown number will be calculated as,
3n + 3 = 6n - 12
6n - 3n = 12 + 3
3n = 15

Find xy if x + y=3, x^2 + y^2 = 5
Answer:
mark me
Step-by-step explanation:
x+y=3
x=3-y
putting the value of x
in this
x²+y²=5
(3-y) ²+y²=5
9-6y+y²+y²=5
2y²-6y+9-5=0
2y²-6y+4=0
2y²-4y-2y+4=0
2y(y-2)-2(y-2)=0
(2y-2) (y-2) =0
2y-2=0 or y-2=0
y=1 or y=2
so x=2 or 1
so x×y=2×1 or 1×2=2

Step-by-step explanation:
The given triangle is a right triangle, this is indicated by the box around one of the angles, signifying that the angle is a (90) degree angle. Therefore, to solve this problem one must use trigonometric ratios. These ratios are used to describe the relationship between an angle and the sides in a right triangle.
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}\\[/tex]
Bear in mind, the names of the sides of the triangle are relative to the angle that one uses to describe it in the triangle. Therefore the (opposite) and (adjacent) sides will change depending on the angle one chooses to look at it from.
In this case, one is given the length of the side opposite the given angle. One is asked to find the measure of the side adjacent to the angle. Therefore, it would make the most sense to use the tangent (tan) ratio.
[tex]tan(\theta)=\frac{opposite}{adjacent}[/tex]
Substitute,
[tex]tan(20)=\frac{9}{x}[/tex]
Manipulate the equation such that it is solved for (x),
[tex]x=\frac{9}{tan(20)}[/tex]
Solve,

Mariano is standing at the top of a hill when he kicks a soccer ball up into the air. The height of the hill is h feet, and the ball is kicked with an initial velocity of v feet per second. The height of the ball above the bottom of the hill after t seconds is given by the polynomial –16t2 + vt + h. Find the height of the ball after 2 seconds if it was kicked from the top of a 60 foot tall hill at 84 feet per second.
The height of the ball after 2 seconds is 100 feet.
What is the height function?
A height function exists as a function that quantifies the intricacy of mathematical objects. The height of an object, h(t), exists defined by the formula [tex]-16 t^{2}[/tex] + vt + h.
Given: Let, the polynomial equation be [tex]-16 t^{2}[/tex] + vt + h
h = 20 ft and v = 72 ft/s
y = [tex]-16 t^{2}[/tex] + 72t + 20
To estimate the height of the ball after 2 seconds
substitute the value of t = 2, then
y = -16 [tex]\times[/tex] 4 + 72 [tex]\times[/tex] 2 + 20
= -64 + 144 + 20
= 100 feet
The height of the ball after 2 seconds is 100 feet.
