what is the unknown angle of a polygon with other angles 85 degrees and 65 degress , first correct answer will become the brainleyest
Answer: 30 degrees
Step-by-step explanation:
Assuming this is a three sided polygon, this would make it a triangle. Interior angles of a triangle sum to 180 degrees. 85+65+u=180
150 + u = 180
U = 30 degrees
The formula for the volume of a pyramid Is V = 1/3 Bh, where V is the volume, B is the area of the base, and h is the height of the pyramid. Cecilia
has a pyramid-shaped candle with a square base. The volume of the candle is 720 cm3 and the area of the base is 36 cm2
Answer:
12
Step-by-step explanation:
so the formula is V=1/3 Bh we dont have h so u just do 1/3 x 36
36 = your base

8 times a certain number is added to 5 times a second number to give 184.the first number minus the second number is -3.find these number .
Answer:
The numbers are 13 , 16
Step-by-step explanation:
First number be x
Second number be y
x - y = -3 --------------------(I)
x = -3 +y
8x + 5y = 184 ---------------(II)
substitute x = -3 + y in equation(I)
8*(-3 + y) + 5y = 184
-24 + 8y + 5y = 184
-24 + 13y = 184
13y = 184 + 24
13y = 208
y = 208/13
y = 16
Plugin y = 16 in (I)
x - 16 = -3
x = -3 +16
x = 13
You and a few friends went to play golf and scored the following.
98, 96, 98, 134, 99
If two other friends join, and score 93 and 117, which part of the data will be effected?
Answer:
The range will change
Step-by-step explanation:
Here, we want to know the part of the data that will be affected
Firstly, we have to understand that the mean will be left unchanged
The mean is the sum of the numbers divided by the count of the numbers;
(98 + 96 + 98 + 134 + 99)/5 is same as (98 + 96 + 98 + 134 + 99 + 93 + 117) = 105
The median will be the same
before the addition of the two new numbers;
96,98,98,99, 134
The median is 98
adding the two;
93,96,98,98,99,117,134
The mode will still be the same as the highest in frequency will still be 98
however the range will change
This is the difference between the highest and the lowest numbers
Before the addition of the two numbers, the range is 134-96 = 38
adding the two numbers, the range will become;
134-93 = 41

Answer:
7.2
Step-by-step explanation:
So it says they all have the same area
6 * 6 = 36
4 * 9 = 36
So now you can divide to find the answer of Figure 2
36 divided by 5 is 7.2
You can check you your answer by multiplying
5 * 7.2 = 36
Answer:
x = 7.2
Step-by-step explanation:
you would divide 5 by 36 because each of the other shapes are equivalent to each other :D

Answer:
BC=53.68
Step-by-step explanation:
Use tangent since you are finding the opposite side and given the adjacent side.
tan(54)=BC/39
BC=53.68
Answer:
C
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan54° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{39}[/tex] ( multiply both sides by 39 )
39 × tan54° = BC, then
BC ≈ 53.68 ( to 2 dec. places ) → C

Nick is making a fruit salad. He buys apples for $1.29 per pound and oranges for $1.35 per pound. He spends no more than $12.
Let x represent the number of pounds of apples that Nick buys. Let y represent the number of pounds of oranges that Nick buys.
Which inequality represents this situation?
1.29x+1.35y>12
1.29x+1.35y≥12
1.29x+1.35y≤12
1.29x+1.35y<12
Answer:
it will be the third one 1.29x+1.35y<_12
Answer: 1.29x+1.35y<_12
Nathan is saving up to buy a new phone. He already has $90 and can save an additional $10 per week using money from his after school job. How much total money would Nathan have after 4 weeks of saving? Also, write an expression that represents the amount of money Nathan would have saved in w weeks.
Answer:
$130
Step-by-step explanation:
If Nathan already has $90 then you would add the amount of money collected after the 4 weeks. In each week he makes $10.
The equation would be $90+($10x4)= $X
oh god does anyone understand this? I need help it’s for a test and I wanna do good!!
Answer:
A
Step-by-step explanation:
Its a right angle, so you have to use trigonometry.
To find x , you use sin60° = opposite/hypotenuse
opposite = x and hypotenuse = 5 . So,
sin60°= x/ 5
5sin60° = x
put the value into your calculator you ' ll get:
[tex] x = \frac{5 \sqrt{3} }{2} [/tex]
To find y, cos60°= adjacent/hypotenuse
adjacent= y and hypotenuse = 5. So,
cos60°= y/5
5cos60°=y
[tex]y = \frac{5}{2} [/tex]
Hope I was able to help. Good luck!<3
Triangle ABC is taken to triangle A'B'C' by a dilation. Which of these scale factors for the dilation would result in an image that was larger than the original figure? Select all correct answers. A
Answer:B
Step-by-step explanation:
For [K] > 0, the dilated image will be larger than the original image.
What is triangle?
A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given is a triangle ABC which is taken to triangle A'B'C' by a dilation.
After dilation by scale factor [K], the length of the sides of triangles change by the following rule -
A'B' = K(AB)
B'C' = K(BC)
C'A' = K(CA)
If K < 0, the image will shrink. If K > 0, the image will enlarge
Therefore, for [K] > 0, the dilated image will be larger than the orginal image.

if f(x) = 3x^2 and g(x) = √2x what is the value of (f o g)(8)?
The value of the composite function (f o g)(x) is 48
How to evaluate the composite function?The functions are given as
f(x) = 3x²
g(x) = √2x
The composite function definition is given as
(f o g)(x)
This composite function is calculated using the following composite function formula
(f o g)(x) = f(g(x))
So, we have:
(f o g)(x) = 3(g(x))²
Substitute the known values in the above equation
So, we have the following equation
(f o g)(x) = 3(√2x)²
Set x = 8
So, we have
(f o g)(x) = 3(√(2 x 8))²
Evaluate the expression
(f o g)(x) = 48
Hence, the composite function (f o g)(x) is 48
