51. Find the length of the unknown side x of this triangle, evaluate your answer to two decimal places.
Answer:
See work, below.
Step-by-step explanation:
The radius of this circle is 10 and so the diameter is 20. The measure of the angle opposite side x is found as follows:
adj side
cos theta = ------------------- = 18/20. Find theta:
hypotenuse
theta = arccos 18/20 = 0.451 radian.
Now use the sine function to find x:
x x
sin 0.451 radian = ------------------- = ------------- = 0.651
hypotenuse 20
which results in x = 20(0.651) = 13.02
x = 13.02 units
I should have used the Pythagorean Theorem up front.
18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72

How do you find the area of a triangle?
Example on picture
Answer:
To find the area of the triangle, you have to follow the formula 0.5*b*h. B is the length of the base of the triangle, and h is the height.

Answer:
S = S(ABCD) - S(BCE) - S(AED) = 7*6 - 2*6/2 - 5*6/2 = 42 - 6 - 15 = 21
Step-by-step explanation:
If we look at the picture, we can notice that the area we are interested in is S(ABCD) - S(BCE) - S(AED). Y-axis is parallel to AB line since the coordinates of the A and B points have the same X-axis value.
The following calculations happend for figuring out the width for each line:
AB = | -3 - 4 | = 7BC = | -4 - 2 | = 6CE = | 4 - 2 | = 2ED = | 2 - (-3) | = 5AD = | -4 - 2 | = 6The formulas for each figure area:
S(ABCD) = AB * BCS(BCE) = BC * CE / 2S(AED) = ED * AD / 2I really need help finding the surface area
A right rectangular prism has a length of 2 ½ feet, a width of 3 feet, and a height of 1 ½ feet. Unit cubes with side lengths of ½-foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?
Answer:
n=90
Step-by-step explanation:
As I think it is easy to answer the volume of prism I will also calculate no of small prism that can fit inside the larger one
so volume = length * width * height
volume of larger prism
vp=45/4 ft^3 =11.25
volume of small cubes
vs=1/2*1/2*1/2
vs=0.125 ft^3
now numbers of cube that can fit
n=vp/vs
n= 11.25/.125
n=90
so 90 smaller cubes will completely fill in the prism
Answer:
11.25 [tex]ft^3[/tex]
Step-by-step explanation:
2.5 x 3 x 1.5 = 11.25 [tex]ft^3[/tex]

Answer:
x ≥ -4
Step-by-step explanation:
you subtract 10 on both sides to get x by itself. 6-10 = -4. since you already have x by itself you don’t have to do anymore
Answer:
The answer is x ≥ -4
Step-by-step explanation:
First, subtract 10 from both sides.
x + 10 ≥ 6
- 10 - 10
Which would make x ≥ -4.

Answer:
Part A: 5
Step-by-step explanation:
4+ 3+ 4+ 5+ 6+ 6+ 8+ 4= 40
so there is 8 numbers which means that we need to do 40 divided by 8=5
Part b: i dont know how to explain but the mad is 1.25.
The mean of given data is 5 and mean deviation is 1.25
What is mean deviation?The mean deviation is defined as a statistical measure that is used to calculate the average deviation from the mean value of the given data set.
Mean = Sum of all observation/ Number of observation

28 out of 50 8th graders said they prefer snow to rain. 42 out of 58 10th graders said they prefer snow. did a larger percentage of 8th graders or 10th graders prefer snow?
explanation please
Answer:
10th graders prefered snow then 8th graders did.
Step-by-step explanation:
Hey I hope I will be able to help!
To find out the percentage we need to divide the fractions-
28 divided by 50 = 0.56 and in percentage form its 56%
42 divided by 58 = approximately 0.72 which is 72%
56% < 72%
72% is obviously greater so 10th graders prefer snow more than 8th graders do.
