Answer:
[tex]Average = 68.25cm[/tex]
Step-by-step explanation:
Given
[tex]n = 8[/tex]
[tex]Lengths: 56\ 45\ 110\ 77\ 87\ 61\ 74\ 36[/tex]
Required
Determine the average ---- [Missing information]
This is calculated as:
[tex]Average = \frac{\sum x}{n}[/tex]
So:
[tex]Average = \frac{56 + 45 + 110 + 77 + 87 + 61 + 74 + 36}{8}[/tex]
[tex]Average = \frac{546}{8}[/tex]
[tex]Average = 68.25cm[/tex]

How can you use ratios to determine if two figures are similar?
Answer:
Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor .

You deposit $300 in a savings account. The account earns 2% simple interest per year.
a. What is the interest earned after 10 years?
The interest earned is $ after 10 years.
b. What is the balance after 10 years?
The balance is $ after 10 years.
Answer:
Answer:
a. ----> $10
b. ----> $110
Step-by-step explanation:
Step-by-step explanation:
principle ( p ) = $100
time ( t ) = 10 years
rate ( r ) = 11%
simple interest = (p × r × t)÷ 100
= ( $100 × 11 × 10 )÷ 100
= 11000 ÷ 100
= $110
interest = simple interest - principle
interest = $110 - $100
= $10
What is X and Y? I will give brainliest to whoever shows work and explains how to do the problem and if its correct.
Answer:
x = 5([tex]\sqrt{3}[/tex])
y = 10
Step-by-step explanation:
1st, we need to find the angles on the triangle before we can solve for side lengths.
Line Y is intercepted by line X which forms 2 supplementary angles.
These angles add up to 180 so 180 - 150 = 30 therefor the angle is 30 degrees
Next, using the vertical angle theorem, we see that there is a right angle and using this theorem, we can determine this is a right triangle and that angle is 90 degrees
Using the triangle sum theorem, we know a triangle's sum is = to 180 degrees
90 + 30 + x = 180
120 + x = 180
x = (180 - 120)
x = 60
We now determined this is a 90-60-30 triangle
The opposite of the 30 degree angle is the 5 unit measurement
According to this theorem 5 is equal to x because the side opposite of the 30 degree angle is = to x (not the side variable, the variable for this theorem)
We now solve the rest
x = 5
2x (opposite of 90 degrees) = 10
5x = 5([tex]\sqrt{3}[/tex]) (This is in its simplest form)
So now based upon this,
x = 5([tex]\sqrt{3}[/tex])
y = 10

If the radius and the slant height of this right circular cone are each multiplied by 4, by what factor is the surface area multiplied?
Answer:
16
Step-by-step explanation:
Total surface area of a cone T1 = πr(r+l)
If the radius and the slant height of this right circular cone are each multiplied by 4, the new surface area will be expressed as;
T1 = π4r(4r+4l)
T2 = 16πr(r+l)
Taking the ratio of both total area
T1/T2 = πr(r+l)/16πr(r+l)
T1/T2 = 1/16
16T1 = T2
T2 = 16 T1
Hence the total surface area is multiplied by a factor of 16
Answer:
16

Answer:
55°Step-by-step explanation:
Angle formed by two intersecting chords is half the sum of the intercepted arcs:
m∠CED = 1/2(mCD + mBU)125° = 1/2(195° + mBU)195° + mBU = 250°mBU = 250° - 195°mBU = 55°What is “F” in this triangle problem thingy
Answer:
f=43
Step-by-step explanation:
Hey There!
So if you didn't know the exterior angle (aka f) is equal to the sum of the opposite interior angles
so essentially what i am saying is that
19+24=f
19+24=43
therefore
f=43
hope this helps :)

Step-by-step explanation:
How to find mean: add up all the numbers and divide by how many numbers
19, 19, 20, 20, 20, 21, 22, 22, 22, 22, 23
(19+19+20+20+20+21+22+22+22+22+23)/11=230/11=20.9(rounded)
If the new mean is 22, sum of all the numbers is 22 times 12=264
264-230=34(new player age)

Answer:
This shape is a hexagon. Angles in a hexagon add to 720 degrees.
2(y) + 4(2y-20) = 720
2y + 8y-80 = 720

A x=56
B x=156
C x=166
D x=66
D: x=66
Step-by-step explanation:
As we know the angle is 90 degree.Then x+24 degree is equal to 90 degree as whole part axiom. If we subtract 24 from 90 we get 66

What is the area of this figure?
Enter your answer in the box.
Answer:
84
Step-by-step explanation:
square: 6mm * 6mm = 36mm
triangle 1: (8mm * 6mm) 0.5 = 24mm
triangle 2: (8mm * 6mm) 0.5 = 24mm
add all of it up to get the entire area
36 + 24 + 24 = 84
