2(6) = y
y = 12
Find the slope that passes through the two points. (9,3) and (6,7)
Answer:
m=4/-3
Step-by-step explanation:
the equation for slope (m) when given two points is (y2-y1)/(x2-x1)
we are given the points (9,3) and (6,7)
we can label the points:
x1=9
y1=3
x2=6
y2=7
now substitute into the equation
m=(7-3)/(6-9)
subtract
m=4/-3
the slope is 4/-3

Answer:
71.13
Step-by-step explanation:
The half area of a circle is A = 1/2 * pi*r^2 = 1/2 * pi * 3^2 or 9
The trapezoid is a rectangle and a triangle. Rectangle is 8*6 and the triangle is 6*(11 - 8) * 1/2
The total is 1/2 * pi * 9 + 8*6 + 6*(11 - 8) * 1/2 = 71.13

Use the table below to determine the approximate height of the flag pole.
Answer:
B 17.5 ft
Step-by-step explanation:
tangent = opposite / adjacent
tan 35° = h / 25
multiply both sides by 25
h = 25 (tan 35°)
tan 35° = 0.70 (from your calculator)
h = 25 (0.70)
h = 17.51 ft.

Expand the following. In other words, remove the parentheses (brackets):
-5(2x - 4y)
B -10x + 20y
A 10xy
C -10x - 20y
D 10x - 20y
Answer:
B
Step-by-step explanation:
-5(2x-4y)
-5*2x = -10y
-5*-4y = 20y
So, -10x+20y
Cone a and cone b both have a height of 5 in. The volume of cone a is 20.9cubic in, the volume of cone b is 4 times the volume of cone a, about how many times longwr is the diameter of cone b than the diameter of cone a?
Answer: two times
Step-by-step explanation:
Given
height of cone A and B [tex]h_a=h_b=5\ in.[/tex]
The volume of cone A [tex]V_a=20.9\ in.^3[/tex]
The volume of cone B is 4 times of cone A
the volume of a cone is [tex]\frac{1}{3}\pi r^2h[/tex]
The volume of cone A
[tex]V_a=\dfrac{1}{3}\pi r_a^2h_a=20.9\quad \ldots(i)[/tex]
The volume of cone B
[tex]V_b=\dfrac{1}{3}\pi r_b^2h_b=4\times 20.9\quad \ldots(ii)[/tex]
divide (i) and (ii) we get
[tex]\Rightarrow \dfrac{r_a^2}{r_b^2}=\dfrac{1}{4}\\\Rightarrow \dfrac{r_a}{r_b}=\sqrt{\dfrac{1}{4}}=\dfrac{1}{2}\\\Rightarrow \dfrac{d_a}{d_b}=\dfrac{1}{2}\\\Rightarrow d_b=2d_a[/tex]
thus, diameter of cone B is twice the diameter of A

Answer:
{-5/4, 8}
Step-by-step explanation:
We are given (4u + 5)(8 - u) = 0. Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:
4u + 5 = 0 leads to u = -5/4, and
8 - u = 0 leads to u = 8.
The solutions are {-5/4, 8}
What is the approximate difference in the circumference of a circle with a radius of 4 ft and the circumference of a circle with a radius of 6 ft?
Answer: 12.57 ft
Step-by-step explanation:
Circumference of circle with radius of 4ft.
= π * radius * 2
= 22/7 * 4 * 2
= 25.14 ft
Circumference of circle with radius of 6ft.
= 22/7 * 6 * 2
= 37.71 ft
Difference = 37.71 - 25.14
= 12.57 ft
If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards
Question isn't well formatted :
If I have 48 cards and and gave 10 to my friend and I have 38 left. what fraction of original number of card do I have left.
Answer:
0.7917
Step-by-step explanation:
If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards
Given that :
Total number of cards = 48
Number given to friend = 10
Number of cards left = 48 - 10 = 38
Number of cards left / original number of cards
38 / 48
= 0.7917
