Answer:
Hypotenuse
Step-by-step explanation:
For this problem you are given the vertical and horizontal sides of the triangle. The flagpole (6.5 meters) is the up-and-down triangle side and the distance from the hook to the flagpole is the base (5.2 meters) of the triangle.

A trade magazine routinely checks the drive-through service times of fast-food restaurants. Upper AA 9595% confidence interval that results from examining 773773 customers in one fast-food chain's drive-through has a lower bound of 169.0169.0 seconds and an upper bound of 172.2172.2 seconds. What does this mean?
Answers
Answer:
One can be 95% confident that the drive-through service times of fast-food chain is between 169 seconds and 172 seconds.
Step-by-step explanation:
The confidence interval gives a range of value for the population mean or parameter, which is calculated from the statistic value of the data (that is sample statistic). This range gives the interval which is associated with a certain level of confidence for which the interval will contain the true value of the unknown parameter (true value). In the scenario above, the associated confidence level is 95%.Hence, we can be 95% confident that the true value will be continued with the interval (169 ; 172)

Los lados de un triángulo rectángulo tienen por medida tres números enteros consecutivos. Calcula los lados del triángulo.
Answers
Answer:
Los lados del triángulo rectángulo miden 3, 4 y 5, respectivamente.
Step-by-step explanation:
Un triángulo rectángulo puede ser descrito mediante el teorema de Pitágoras, para el caso de tres lados representando tres números enteros consecutivos, tenemos que:
[tex](n+2)^{2} = n^{2} + (n+1)^{2}[/tex] (1)
Donde [tex]n[/tex] es un número natural.
A continuación, expandimos la expresión y resolvemos:
[tex]n^{2}+4\cdot n +4 = n^{2} + n^{2} +2\cdot n + 1[/tex]
[tex]n^{2}-2\cdot n -3 = 0[/tex]
[tex](n -3) \cdot (n+1) = 0[/tex]

Laura takes 80 steps to walk across her local park.
Laura's steps are 70 centimetres long.
Her sister Kara's steps are 80 centimetres long.
How many steps does Kara take to walk across
the park?
a. 45
b.56
c.70
d.80
Answers
Answer:
c. 70
Step-by-step explanation:
Laura’s steps are 70cm, and she takes 80 steps, which would give her a total length of 5600cm. Kara’s steps are 80cm, so we have to divide 5600cm by 80cm. This means Kara takes 70 steps to walk across the park.

The length of the base of a rectangle is increased by 10% but the area remains unchanged. By what percent was the breadth reduced?
Answers
Answer:
9.09%
Step-by-step explanation:
Area of a rectangle = length x breadth
to determine the answer, i would use an example
Assume length = 10
breadth 20
Area = 10 x 20 = 200
If the length is increased by 10%, the new length becomes = 1.1 x 10 = 11
11 x b = 200
b = 200/11 = 18.181818
Percentage reduction = (18.181818 / 20) - 1 = 0.0909 = 9.09%

1. Find the area of the composite figure to the nearest hundredth.
2. Find the area of the shaded region to the nearest tenth.
Answers
Answer:
#1: 751.56 mm²
#2: 477 km²
Step-by-step explanation:
First I noted the semicircle on the left, which has a radius of 12.5 mm. The formula for finding the area of a semicircle is 1/2(πr²).
1/2(3.14 * (12.5)²)
12.5 squared is 156.25.
1/2(3.14 * 156.25)
Multiply 3.14 by 156.25 to get 490.625.
1/2(490.625)
Divide 490.625 by 2 to get 245.3125.
245.3125 mm² for the semicircle
Then, I split the rest of into a 12.5 by 25 rectangle and a 31 by 12.5 triangle.
(12.5 * 25) + 1/2(31 * 12.5)
Multiply 12.5 by 25 to get 312.5.
312.5 + 1/2(31 * 12.5)
Multiply 31 by 12.5 to get 387.5.
312.5 + 1/2(387.5)
Multiply 1/2 by 387.5 to get 193.75
312.5 + 193.75
Add 312.5 and 193.75 to get 506.25.
506.25 mm² for the rest of the figure.
Now add the two measures, and you have your answer for #1.
245.3125 + 506.25 = 751.5625 mm², which rounds to 751.56 mm².
The area of the composite figure is 751.56 mm².
Now for #2. First, find the area of the triangle.
1/2(40 * 27)
Multiply 40 by 27 to get 1080.
1/2(1080)
Multiply 1/2 by 1080.
590 km² for the triangle.
Now find the area of the circle.
3.14 * 6²
3.14 * 36
113.04 km² for the circle.
Now subtract the area of the circle from the area of the triangle.
590 - 113.04
476.96 km², which rounds to 477.0 km².
The area of the shaded region is 477 km².
Answer:
1. 745.31 mm²2. 426.96 km²Step-by-step explanation:
#1
We can separate the figure into 3 parts and sum the areas.
Semicircle with radius 12.5 mm:
A = 1/2(πr²) = 1/2(3.14*12.5²) = 245.31 mm²Rectangle with sides 12.5 mm and its double size:
A = 12.5*(2*12.5) = 312.5 mm²Triangle with height 12.5 mm and base 30 mm:
A = 1/2*(55 - 2*12.5)*12.5 = 187.5 mm²Sum of the three:
245.31 + 312.5 + 187.5 = 745.31 mm²#2
The shaded region is the difference of the areas of the triangle and the circle
Triangle:
A = 1/2*27*40 = 540 km²Circle:
A = πr² = πd²/4 = 3.14*12²/4 = 113.04 km²Shaded region:

of the ball after t seconds can be modeled by the equation h=-16tsqaured +44t +5
A. After how many seconds does the ball reach a height of 15 feet?
B. After how many seconds does the ball hit the ground? Round your answer
to two decimal places.
Answers
Answer:
A. After 2.5 sec and .25 sec the ball was at a height of 15 ft.
B. 2.86 sec is the time it takes to hit the ground
Step-by-step explanation:
A. let h = 15
then 15 = -16t^2 + 44t + 5
16t^2 - 44t + 10 =0
2(8t^2 - 22t + 5) = 0
2(2t - 5)(4t - 1) = 0
t = 5/2 = 2.5 or t = 1/4 = .25
After 2.5 sec and .25 sec the ball was at a height of 15 ft.
B. Let h = 0.
-16t^2 + 44t + 5 = 0
Use the quadratic formula to find t. (I will let you do that)
t = 2.85929... or t = -.10929...
t cannot be negative, so 2.86 sec is the time it takes to hit the ground
The answer of A is After 2.5 sec and 0.25 sec the ball was at a height of 15 ft and the answer of B is 2.86 sec is the time it takes to hit the ground.
A. let h = 15
What is the quadratic equation?
[tex]ax^2+bx+c=0[/tex]
a, b, c = known numbers, where a ≠ 0
x = the unknown
then 15 = -16t^2 + 44t + 5
16t^2 - 44t + 10 =0
2(8t^2 - 22t + 5) = 0
2(2t - 5)(4t - 1) = 0
t = 5/2 = 2.5 or t = 1/4 = 0.25
After 2.5 sec and 0.25 sec the ball was at a height of 15 ft.
B. Let h = 0.
-16t^2 + 44t + 5 = 0
Use the quadratic formula to find t.
t = 2.85929... or t = -.10929...
t cannot be negative, So 2.86 sec is the time it takes to hit the ground.
