Answer:
31
Step-by-step explanation:
The entire straight line is 180 degrees. So, if angle a is 25 degrees we would subtract that from 180. This would give us 155 degrees. You would then add 2x and 3x together to get 5x. 155/5x would be 31. Your x value is then 31.
Answer and Step-by-step explanation:
We know that a is equal to 25.
Let's subtract that from the entire angle measure of line segment AB, which is 180.
180 - 25 = 155.
Now, we need to find the value of x. We can do this by adding together the other two angles, and equal it to 155.
155 = 2x + 3x
155 = 5x
31 = x
So, the value of x is 31.

C. 6
D. 35
Answer:
B
14
I think it is right :D
Step-by-step explanation:
Answer: B, 14
Step-by-step explanation:
The median is the number in the middle of the set if the numbers are in order.
And if there is an odd amount of numbers.
The number in the middle of the list is 14.
If the list doesn't have an odd amount of number you add the 2 middle ones and take the average so divide by 2.

Helppp law of sines and law of cosines
Answer:
[tex]\displaystyle ST ≈ 15,9\\ RT ≈ 30,8 \\ m∠S = 111°[/tex]
Step-by-step explanation:
First off, find [tex]\displaystyle m∠S:[/tex]
[tex]\displaystyle 180° = 58° + 31° + m∠S → 180° = 89° + m∠S \\ 111° = m∠S[/tex]
Now that the third angle has been defined, we can move move forward with solving for a second edge, using the Law of Sines, but before proceeding, here are some things you should know about this triangle:
Edge s [RT] → [tex]\displaystyle m∠S[/tex]Edge t [RS] → [tex]\displaystyle m∠T[/tex]Edge r [ST] → [tex]\displaystyle m∠R[/tex]Now that we have the information, we can proceed with the process:
[tex]\displaystyle \frac{t}{sin∠T} = \frac{s}{sin∠S} = \frac{r}{sin∠R} \\ \\ \frac{28}{sin\:58°} = \frac{s}{sin\:111°} → \frac{28sin\:111°}{sin\:58°} → 30,82402055... = s \\ 30,8 ≈ s[/tex]
_______________________________________________
Now that RT has been defined, we can now proceed to solving the third edge, using the Law of Cosines:
[tex]\displaystyle s^2 + r^2 - 2sr\: cos∠T = t^2 \\ t^2 + r^2 - 2tr\: cos∠S = s^2 \\ t^2 + s^2 - 2ts\: cos∠R = r^2 \\ \\ 28^2 + 30,8^2 - 2[28][30]\: cos\:31° = r^2 → 784 + 948,64 - 1680\: cos\:31° = r^2 → \sqrt{254,1978397...} = \sqrt{r^2} → 15,94358303... = r \\ 15,9 ≈ r[/tex]
Your triangle is now complete!
I am joyous to assist you at any time.
Answer:
Step-by-step explanation:
In this case, you would use law of sines due due you being given two angles and one side.
LAW OF ANGLES IN TRIANGLES: 180 - a - b = c
So in this case: 180 - 31 - 58 = m<S = 91
LAW OF SINE: sin A / a = sin B / b = sin C / c
So in this case: sin 31 / ST = sin 58 / 28
28 sin 31 / sin 58 = ST = 17.0
sin 58 / 28 = sin 91 / x
28 sin 91 / sin 58 = RT = 33.0
Gerardo works at an ice cream shop each flavor of ice cream is stored in a right cylindrical tub that measures approximately 9 inches high with a radius of 5 inches Gerardo uses an ice cream scoop that makes spherical scoops of ice cream with a diameter of 2.5 inches If gerardo opens a new tub of chocolate ice cream and scoops 37 scoops of chocolate ice cream about how much chocolate ice cream in cubic inches is left in the tub
Answer:
Volume left = 404.32 cubic inches
Step-by-step explanation:
volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h
volume of ice cream in the cylindrical tub = [tex]\frac{22}{7}[/tex] x [tex]5^{2}[/tex] x 9
= [tex]\frac{22}{7}[/tex] x 25 x 9
= 707.1429
Volume of ice cream in the cylindrical tub is 707.14 cubic inches.
The ice cream scoop has a spherical volume, so that;
volume of a sphere = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]
r = [tex]\frac{2.5}{2}[/tex]
= [tex]\frac{5}{4}[/tex] inches
volume of the scoop = [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](\frac{5}{4} )^{3}[/tex]
= [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex]\frac{125}{64}[/tex]
= 8.1845
volume of the scoop is 8.19 cubic inches.
If he scoops 37 scoops,
volume of the 37 scoops = 37 x 8.1845
= 302.8265
volume of 37 scoops is 302.83 cubic inches.
Volume of ice cream left in the tub = 707.1429 - 302.8265
= 404.3164
Volume of ice cream left in the tub is 404.32 cubic inches.

x + y=-11
2x – 3y = 3
• (-6, -5)
•(15,-4)
• (6, 1)
• (-10, -1)
Answer:
(-6,-5)
Step-by-step explanation:
X+y=-11
solve for x
x=-11-y
substiute x value into 2nd equation
2x-3y=3
2(-11-y)-3y=3
-22-2y-3y=3
-5y=25
y=-5
substitute -5 for y in either equation to find x
x+y=-11
x+-5=-11
x=-6
Find the area of the shaped region
Answer:
Assuming π is represented by 3.14, the correct answer is [tex]50.24m^2[/tex].
Step-by-step explanation:
Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is [tex]\pi r^2[/tex], where r is the radius of the circle. Since the radius of the shaded circle is [tex]4m[/tex], you can infer that the area of the shaded region would be [tex]4^2 * 3.14[/tex] = [tex]16*3.14[/tex] = [tex]50.24m^2[/tex].

PLEASE HELP I WILL MARK BRAINLIEST!!
Answer:
79 degrees.
Step-by-step explanation:
There are 7 total temperatures, 68, 82, 81, 82, 74, 75, and 91 degrees. To find the mean, we add all of the temperatures together and divide it by the number of tempuratures-- 7.
68+82+81+82+74+75+91 = 553.
553 / 7 = 79.

Which of the following correctly shows the length of each radius, the point where the circles intersect, and the equation of the tangent line at this point?
Answer:
Length of the radii of the circles → 4 units and 1 unit
Equation of common tangent → x = 4
Step-by-step explanation:
From the figure attached,
Length of radii of each circles are,
Radius of circle S = 4 units
Radius of circle T = 1 unit
Common point where the circles are touching → (4, 1)
Common tangent to these circles is a line perpendicular to x-axis passing through x = 4,
Equation of the tangent will be,
x = 4

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
From the triangle it can be assume that ΔPSR is similar to ΔPQR.
Then, the ratio of corresponding sides of triangles are proportion.
So, PQ/ PS = QR/ RS
