Answer:
c. 10 cm
Step-by-step explanation:
The parallel sides of trapizium are the bases so
base 1(B1) =9cm , base(B2)= 12cm
[tex]area(a) = 105 {cm}^{2} [/tex]
the perpendicular distance means the height so lets find the height
area of trapizium= B1 + B2 × h
2
[tex] {105cm}^{2}(the \: given \: area) = \frac{9cm(the \: given \: base) + 12cm(the \: given \: base)}{2} \times h[/tex]
[tex] {105cm}^{2} = \frac{21cm}{2} \times h[/tex]
now we crisscross
[tex] {105cm}^{2} \times 2 = 21cm \times h [/tex]
[tex] {210cm}^{2} = 21cm \times h[/tex]
[tex] \frac{ {210cm}^{2} }{21cm} = \frac{21cm \: }{21cm} \times h[/tex]
h = 10 cm

A parachutist's rate during a free fall reaches 117 miles per hour. What is this rate in feet per second? At this rate, how many feet will the parachutist fall during 10 seconds of free fall? In your computations
Answers
Answer:
1. rate = 171.6 feet/second
2. 1716 feet
Step-by-step explanation:
1. To convert from miles per hour to feet per second,
1 mile = 5280 feet
117 miles = 617760 feet
1 hour = 3600 seconds
Thus the rate in feet per second will be;
= [tex]\frac{617760}{3600}[/tex]
= 171.6 feet/second
2. In 10 second of free fall,
speed = [tex]\frac{distance}{time}[/tex]
distance = speed x time
= 171.6 feet/second x 10 second
= 1716 feet
The parachutist would fall 1716 feet in 10 seconds of free fall.

simplify 9 - 8b + 6b
Answers
Answer:
9-2b should be your answer.
9 + -8b + 6b = 0
Combine like terms: -8b + 6b = -2b
9 + -2b = 0
Solving
9 + -2b = 0
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + -2b = 0 + -9
Combine like terms: 9 + -9 = 0
0 + -2b = 0 + -9
-2b = 0 + -9
Combine like terms: 0 + -9 = -9
-2b = -9
Divide each side by '-2'.
b = 4.5
Simplifying
b = 4.5
The sum of 2 consecutive odd integers is 204. What are the two odd integers?
Answers
101 and 104 i think is the most easy answer
Answer:
101, 103
Step-by-step explanation:
Say n is the first odd integer. The sum of n and its consecutive integer can be written as n + (n + 2). Doing some simple algebra:
n + (n+2) =204
2n + 2 = 204
2n = 202
n = 101
n is 101, and its consecutive integer, (n+2), is 103.
The endpoints of a diameter of a circle are A(1,2) and (7.10). Find the area of the circle in terms of pi
Answers
Answer:
25pi
Step-by-step explanation:
To solve this, create a right triangle between the two points. We know the distance of one leg is 6, and the distance of the other leg is 8. Use the Pythagorean theorem to solve for the diameter. You substitute 6 and 8 into the values of A and B. Once you get this, you get (6^2)+(8^2)=c^2. Once you further simplify this, you get 36 + 64 = c^2, which is 100 = c^2. Take the square roots of both sides to get the diameter as 10. Divide the diameter by 2 to get the radius. Square the radius and multiply it by pi to get the area. Doing this will get the result of 25 pi.

5 MINS LEFT! A group of students decides to sell pizzas to help raise money for their senior class trip. They sold a pepperoni pizza for $14, a sausage pizza for $11, and a cheese pizza for $10. At the end of their sales, the class sold a total of 400 pizzas and made $4560. The students sold 80 more cheese pizzas than pepperoni pizzas. How many of each type of pizza were sold?
Answers
Answer:
The number of cheese pizza sold is 200 cheese pizzas
The number of sausage pizza sold is 80 sausage pizzas
The number of pepperoni pizza sold is 120 pepperoni pizzas
Step-by-step explanation:
The price at which the pepperoni pizza was sold is $14
The price at which the sausage pizza was sold is $11
price at which the cheese pizza was sold is $10
The total number of pizzas sold = 400
The total amount made = $4560
The number of cheese pizza sold = 80 + the number of pepperoni pizzas
Let the number of cheese pizza sold = C
The number of sausage pizza sold = S
The number of pepperoni pizza sold = P
We have;
C + S + P = 400..........................(1)
C = 80 + P...................................(2)
10·C + 11·S + 14·P = $4560.......(3)
Substituting the value for C from equation (2) in equation (1), we get;
C + S + P = 400 = 80 + P + S + P = 400
2·P + S = 400 - 80 = 320
∴ S = 320 - 2·P..........................(4)
Substituting the value for C from equation (2) and the value for S from equation (4) into equation (3), we get;
10·C + 11·S + 14·P = $4560
10·(80 + P) + 11·(320 - 2·P) + 14·P = 4560
800 + 10·P + 3,520 - 22·P + 14·P = 4560
4,320 + 2·P = 4560
2·P = 4560 - 4,320 = 240
P = 240/2 = 120
P = 120
C = 80 + P = 80 + 120 = 200
C = 200
S = 320 - 2·P = 320 - 2×120 = 320 - 240 = 80
S = 80
Therefore;
The number of cheese pizza sold = C = 200
The number of sausage pizza sold = S = 80
The number of pepperoni pizza sold = P = 120.

Isosceles triangle ABC has a perimeter of 96 centimeters. The base of the triangle is Line segment A C and measures 24 centimeters. What is the measure of Line segment A B? 12 cm 36 cm 48 cm 72 cm
Answers
Answer: 36cm
Step-by-step explanation:
An isosceles triangle has 2 sides equal and one different from the other 2. Let's take the segment A C which measures 24cm as the base of our triangle, that means we'll have two equal unknown segments A B and B C. The perimeter of a shape is in simpler terms the distance right round it, therefore, if we add the length of all the three sides of the triangle we should get 96cm.
A C + A B + B C = 96cm
A B = B C
A C = 24cm
96cm - 24cm = 72cm
A B + B C = 72cm
72cm ÷ 2 = 36cm
The length of AB is 36 cm.
An Isosceles triangle ABC has two equal sides.
Let us consider that equal sides AB and CB are x.
Given that, AC = 24cm
Perimeter = AB + CB + AC
[tex]x+x+24=96\\\\2x=96-24=72\\\\x=72/2=36cm[/tex]
Therefore, the length of AB is 36 cm.

Let the height of the flagpole be: x ft.
Now, we can model this problem with the help of a right angled triangle such that the hypotenuse of the triangle is: 20 feet
and one of the leg of the right triangle is: 16 feet
Now, in order to find the other leg i.e. x we need to use the Pythagorean Theorem.

Consider
the linear function f(x) = mx + b, where m = 0, on the interval [3, 7). Explain
why the maximum value of the function over this interval must occur at one
of the endpoints of the interval.
Answers
Answer:
Assuming that m does not = 0, then the function has a non horizontal slope, so the value will increase as the position moves away from zero in either the negative or positive direction depending on whether the slope (m) is negative or positive. The furthest that the position can be from 0 is at one of the endpoints of the interval [3, 7), therefore, the maximum value of the function on the same interval must be at one of the endpoints.

children. Find the intercepts and interpret the meaning of each one.
PLEASE HELP ASAP
Answers
Answer:
Hey there!
The x-intercept is (6,0) meaning that if no children attend, 6 adults will attend.
The y-intercept is (0,14) meaning that if no adults attend, 14 children will attend.
Let me know if this helps :)
The x-intercept is (6,0) and y-intercept is (0,14).
What is x-intercept?x-intercept for "any curve is the value of x-coordinate at the point where the graph cuts the x-axis".
What is y-intercept?
y-intercept for "any any curve is the value of y-coordinate at the point where the graph cuts the y-axis".
According to the question,
3.5x + 1.5y =21
Let 'x' is the number of adults and 'y' is the number of children.
To find x-intercept put y=0.
3.5x + 1.5(0) = 21
3.5x = 21
x = 21/3.5 =6.
To find y-intercept put x=0
3.5(0) + 1.5(y) = 21
y = 21/1.5 = 14.
x-intercept (6,0) if no children attend the play then 6 adult attend the play. y - intercept (0,14) if no adult attend the play then 14 children attend the play.
Hence, The x-intercept is (6,0) and y-intercept is (0,14).
