Answer:
Step-by-step explanation:
m∠ 1 = 180 - 117
m∠ 1 = 63
m∠2 = the same as m∠ 1
m∠2 = 63
m∠3 is also the same b/c of the same length of the "legs" of the triangle
m∠3 = 63

2(x-5)^2=128
This is solving quadratic functions by square roots
Answer:
x = 13 and x = -3
Step-by-step explanation:
divide each side by 2 first and get:
(x-5)² = 64
take the square root of each side next and get:
x - 5 = [tex]\sqrt{64}[/tex]
x - 5 = 8 and x - 5 = -8
x = 13 and x = -3
Answer:
x = 13 and x = -13

Jane incorrectly finds the volume of the cone using the following work. Explain Jan’s error and find the correct volume AND surface area. Show all work
Answer:
V=39.25. the height is not 6.25, 6.25 is the slope. you have to use Pythagoras theorem to find the height, then you can find the volume.
The surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².
What is of volume of cone?
Volume of cones the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
Volume of cone can be given as,
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Here, (r) is the radius of the base of the cone and (h) is the height of the cone.
The height of the cone is 6.5 cm and the radius is 2.5 cm. Put the values in the above formula,
[tex]V=\dfrac{1}{3}\pi r^2h\\V=\dfrac{1}{3}\pi (2.5)^2(6.5)\\V=\dfrac{1}{3}\pi (6.25)^2(6.5)\\V=\dfrac{40.625\pi }{3}\\V\approx42.5\rm\;cm^3[/tex]
The surface area of cone can be find out by the following formula,
[tex]A=\pi r(r+\sqrt{h^2+r^2})[/tex]
Again put the values in this formula,
[tex]A=\pi \times2.5(2.5+\sqrt{(6.5)^2+(2.5)^2})\\A=\pi \times2.5(2.5+\sqrt{48.5})\\A=\pi \times2.5(2.5+6.96)\\A=\pi \times2.5(9.46)\\A=74.33\rm\; cm^2[/tex]
Thus, the surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².

A home business has an average income of $900.00 per month with a standard deviation of $15.00. If the income in a given month is $930.00, what z-score corresponds to this value?
Enter the answer to the nearest tenth. Z= ?
Answer:
2.00
Step-by-step explanation:
Z score is a statistical that corresponds to the standardization of the regular score to a normal distribution
The formula for Z score is Z = [X - mean ]./ (standard deviation)
Here X = 930.00; mean = 900.00; and standard deviation = 15.00
Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00
Does Brainly help with Geometry?
Answer:
Yes!
Step-by-step explanation:
Brainly can function as an algebra practice tool, a geometry solver, and a fraction calculator.
What is Geometry?One of the first areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects. A geometer is a mathematician who specialises in geometry.
The three most popular types of geometry are solid geometry (which deals with items like the line, sphere, and polyhedron) and spherical geometry (which deals with objects like the spherical triangle as well as spherical polygon). Plane geometry deals with objects such as the point, line, oval, triangle, and polygon.
Thus, Brainly can function as an algebra practice tool, a geometry solver, and a fraction calculator.

its a function or not fuction?
answer:
it's a function
step-by-step explanation:
according to g00gle- in mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. typical examples are functions from integers to integers, or from real numbers to real numbers.
but the simple definition is that a function is when the x value isn't being repeated. and since in your case it isn't, the table is a function
another way to solve-
for this, we will put the pairs into a graph then perform the line test-
as you can see each point has its own individual line, therefore, meaning it passed the vertical line test
good luck :)

Find the missing measurements in triangle ABC. Round your answer to the nearest tenth if necessary.
Measure of Angle B=
AB=
AC=
Answer:
m∡B = 55°
AB = 5.2
AC = 7.4
Step-by-step explanation:
m∡B = 180-(90+35)
use Law of Sines to find AB and AC:
sin 90° / 9 = sin 35°/AB
AB = .57(9) = 5.2
sin 90° / 9 = sin 55°/AC
AC = .82(9) = 7.4
The solution is,
m∡B = 55°
AB = 5.2
AC = 7.4
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
here, we have,
from the given figure, we get,
m∡B = 180-(90+35)
=55
use Law of Sines to find AB and AC:
sin 90° / 9
= sin 35°/AB
AB = .57(9)
= 5.2
sin 90° / 9 = sin 55°/AC
AC = .82(9
= 7.4.

Carl has $25.00 to spend o six packs of soda for the dance. If the cost of one-six pack is $2.50, which inequality could be used to represent this relationship?
Answer:
25 ≤ 2.5n
Step-by-step explanation:
Total budgeted amount = $25
Cost per pack of = $2.50
To represent the relationship using inequality :
Let the Total number of packs purchased = n
Hence,
Total budgeted amount ≤ (cost per pack * number of packs)
25 ≤ 2.5n
This means the total actual purchase made should be less than or equal to the budgeted amount.

Answer:
100 cubic in
Explanation
step 1: divide the figure into two
step 2 : find area then multiply by height of the cuboid
step 3 : add both
Answer:
The answer is 100.
Step-by-step explanation:
Volume = weight times height times length = 5 times 1 times 8 = 40
Volume = weight times height times length = 5 times 2 times 6 = 60
So now that we have the volume of each rectangular prism, we must add them together to get the full volume.
60 + 40 = 100
