Answer:
1. 31.3%
2. 34.35%
3.62.6%
Step-by-step explanation:
There were 131 acoustic guitars, and 41 of them needed neck repair.
41/131 = 0.3130 = 31.3%
There were 262 total guitars serviced by Emely. 60 of them were acoustic and needed a string repaired, and 30 of them ere acoustic and needed repair, so 90 of them were acoustic and did not need neck repair.
90/262 = 0.3435 = 34.35%
There were 131 electric guitars. 48 of them had a broken string and 34 of them needed body repairs. So 82 of them needed either string or body repairs.
82/131 = 0.6260 = 62.6%

The area of a rectangular park is 300 sq.M. If the length of the park is 25 m, find the breadth. *
Answer:
Breadth = 12 m
Step-by-step explanation:
Area of a rectangle is given by the formula,
Area = Length × Width
Value of area and length of the rectangular park has been given in this question.
Therefore, by substituting these values in the formula,
300 = 25 × Width
Width = [tex]\frac{300}{25}[/tex]
= 12 m
Therefore, width or breadth of the rectangular park will be 12 m.

8. Find the area of the triangle. (1 point) 16 ft 62 ft Not drawn to scale.
Answer:
Hello! Answer: 496
Step-by-step explanation:
When finding area for triangles we have to do base x height then divide by 2 so
62 x 16 = 992
992 ÷ 2 = 496
So 496 is our answer!
Answer:
A - 496
Step-by-step explanation:
formula for area of a triangle
[tex]a = \frac{bh}{2} [/tex]
where b = base length and h = height
The triangle shown has a base length of 62 ft and a height of 16 ft
That being said we plug in the given values into the formula
[tex]a = \frac{62 \times 16}{2} \\ 62 \times 16 = 992 \\ \frac{992}{2} = 496[/tex]
Hence the area of the triangle is 496 square feet
A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height h (in feet) can be expressed as a function of time t (in seconds) by the equation h = -16t2 + 56t. How much time does the ball take to reach its highest point?
1.75 seconds B) 2.50 seconds C) 2.75 seconds D) 3.50 seconds
Answer:
1.75
Step-by-step explanation:
h(t) = -16t² + 56t
h'(t) = -32t + 56
To find time at max height equate h' to 0
0 = -32t + 56
t = 56/32 = 1.75 s
It takes 1.75 s to reach max highest point

In the isosceles trapezoid below,
x = [? ]°
5x-20°
2x+37°
Answer:
x = 19
Step-by-step explanation:
The lower base angles in an isosceles trapezoid are congruent , then
5x - 20 = 2x + 37 ( subtract 2x from both sides )
3x - 20 = 37 ( add 20 to both sides )
3x = 57 ( divide both sides by 3 )
x = 19

Answer:
45 because it is what I think
given m||n, find the value of x
Answer:
x= 154°
I hope it's helps you
Answer:
x=154
Step-by-step explanation:
The figures provides us with a variable and the number 154.
In this situation, the value of x and the given angle are corresponding angles.
The theorem of corresponding angles states that if a transversal is cut by two parallel lines the corresponding angles are CONGRUENT.
When an angle is congruent, they are equal to each other.
So in this case, x=154, x≅154.
Hope it helps! :)

A sports marketing company is interested in how many hours teenagers in a town spend watching sports. They randomly select 40 teenagers from this town and ask how many hours per week they spend watching sports. The mean amount is 6.25 hours with a standard deviation of 4.33 hours. Which of the following correctly interprets the 90% confidence interval for the true mean number of hours teenagers from this town watch sports?
90% of all teenagers from this town watch sports for the number of hours that lie between the values in the interval.
In repeated sampling, 90% of the time, the true mean number of hours teens from this town watch sports will be 6.25 hours.
The sports marketing company can be 90% confident that the constructed interval captures the true mean number of hours teens from this town watch sports.
In repeated sampling, 90% of the time the true mean number of hours teens from this town watch sports will be captured in the constructed interval.
Answer:
c. The sports marketing company can be 90% confident that the constructed interval captures the true mean number of hours teens from this town watch sports.
Step-by-step explanation:
got it right on edge
The statement third "sports marketing company can be 90% confident that the constructed interval captures the true mean number of hours teens from this town watch sports" is the correct.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
First, we will find the 90% confidence interval:
We have:
X = 6.25 hours, SD =4.33 hours, n = 40
90% confidence interval:
= (X±t×s/√n)
For 90% confidence interval:
t = t(n-1), 1-α/2 = t(39), 0.95 = 1.685
After putting all the values in the above confidence interval, formula:
We get:
Confidence interval = (5.097, 7.404)
Thus, the statement third "sports marketing company can be 90% confident that the constructed interval captures the true mean number of hours teens from this town watch sports" is the correct.

Explain Jan’s error
Answer:
Please check explanations
Step-by-step explanation:
To find the volume of the surface area of a cone, we need to use the height and not the slant height of the cone
The slant height, the height and the base radius forms a right triangle with the slant height being the hypotenuse of this triangle
By Pythagoras’ theorem, the square of the hypotenuse (slant height) equals the sum of the squares of the two other sides
6.5^2 = 2.5^2 + h^2
h^2 = 36
h = √36
h = 6 cm
So we have the volume as;
V = 1/3 * pi * r^2 * h
where r in this case is base radius of 2.5 cm
V = 1/3 * pi * 2.5^2 * 6 = 39.3 cm^3

The radius of a circle is 7 cm. Find its circumference in terms of π.
Solution:-Radius (r) of a circle = 7 cm. (Given)
We know,
[tex] \dag [/tex] Circumference of a circle is 2πr.
So, its circumference is 2 × π × 7
Its circumference is 14π cm.
Its circumference in terms of π is 14π cm. [Answer]Answer:
Radius (r) of a circle = 7 cm. (Given)
We know,
Circumference of a circle is 2πr.

A teacher is making worksheets for the next unit. He can create 3 worksheets in an hour and has 10 worksheets already created from the previous year. Which of the following lengths of time worked will not be long enough for the teacher to have created 27 worksheets. * Check All That Are True*
6 hours, 10 hours, 8 hours, 2 hours, 4 hours
Answer:
2 hours, 4 hours
Step-by-step explanation:
So lets go over what we know.
There are already 10 worksheets created.
Every 1 hour 3 more are made.
27 worksheets need to be made.
Ok, the first thing we can do is subtract the amount of worksheets needed by the amount we laready have:
27-10
=
17
Now, lets divide the amount of worksheets we still need, by how many we make each hour:
17/3
=
Well, 3 goes into 15, 5 times. Then 2 is left. So we know it takes 5 2/3 hours to create all 27 worksheets.
Looking at the answers, 6 hours, 8 hours, and 10 hours would work. However 2 hours and 4 hours would not work.
Hope this helps! ;)
