i’m not sure how to find the slope of the lines
Answer:
Step-by-step explanation:Select any two random points on the graph of the line (preferably with integer coordinates).
Label them as A and B (in any order).
Calculate the "rise" from A to B. While going vertically from A to B, if we have to go
"up", then the rise is positive;
"down", then the rise is negative.
Calculate the "run" from A to B. While going horizontally from A to B, if we have to go
"right", then the run is positive;
"left", then the run is negative.
Now, use the formula: slope = rise/run.
Lani is making a cake in the shape of a cone. to make the cake, she uses a cone shape mold. the mold has a diameter of 10 inches and a height of 12 inches. what is the volume of the cake? use 3.14 for pi. round to the nearest tenth, if necessary. responses 125.6 in³ 125.6 in³ 314 in³ 314 in³ 942 in³ 942 in³ 1256 in³
The volume of the cake Lani is making is 314 inches³.
Volume is defined as the amount of space a figure occupies. The formula for the volume of a cone is given by:
V = πr²h/3
where V = volume
r = radius of the base of the cone
h = height of the cone
π = 3.14
If the cone shape mold has a diameter of 10 inches, then its radius is equal to half of 10 which is 5 inches.
Plug in the values to the formula and solve for the volume.
V = πr²h/3
V = (3.14)(5 inches)²(12 inches)/3
V = 314 inches³
Hence, the volume of the cake is 314 inches³.

Answer:
8.79 in
Step-by-step explanation:
23 = 150/360 × 2×3.14× r
23 = 5/12 × 6.28 x r
23 = 31.4×r / 12
31.4 r = 23×12
31.4 r = 276
r = 276/31.4

Find the measure of the exterior angle with 24 degrees
(3x+6) and (2x+18)
The measure of the exterior angle of the triangle is 114 degrees.
How to find the angles of a triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.
The measure of the exterior angle of the triangle can be found using exterior angle theorem.
Therefore, the exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
Hence,
24 + 2x + 18 = 3x + 6
2x - 3x = 6 - 18 - 24
-x = -36
divide both sides of the equation by -1
x = 36
Hence,
exterior angle = 3x + 6 = 3(36) + 6 = 108 + 6 = 114 degrees

How do you solve a 45 45 90 and 30 60 90 triangle?
All 45-45-90-degree triangles have sides that are in a unique ratio. The two legs are exactly the same length.
This triangle is important because any time we're given one side of a 45-er triangle, we can figure out the other two sides.
If one leg is given, the hypotenuse is calculated by multiplying this length by the square root of 2.The hypotenuse is given, and the leg is calculated by dividing the hypotenuse by the square root of 2.The 30-60-90 degree triangle is half of an equilateral triangle, cut straight down the middle along its altitude. This triangle has angles of 30°, 60°, and 90°.
The shortest leg is over from the 30-degree angle, the length of the hypotenuse is always double the length of the shortest leg,If the hypotenuse is given, the long leg is calculated by dividing the hypotenuse by 2.If the long leg is given, the hypotenuse is calculated by dividing this side by the square root of 3.Read more about 30-60-90 degree triangle:

The average sale price of new one-family houses in the United States for a recent year was . Find the range of values in which at least of the sale prices will lie if the standard deviation is . Round your to the nearest whole number
The price range for 75% of sales will be between $149,300 and $343,300.
What is meant by Chebyshev's Theorem?The minimum percentage of observations falling within a given range of standard deviations from the mean is calculated using Chebyshev's Theorem. Numerous probability distributions can use this theorem. Also known as Chebyshev's Inequality, Chebyshev's Theorem.
Between $149,300 and $343,300 is where 75% of transactions are priced. Only 75% of the distribution's numbers must fall within two standard deviations for Chebyshev's theorem to hold, which makes it weaker than the proportion of numbers that are within two standard deviations of the mean.
Since the standard deviation given exists 48500, 2 standard deviations will be 2 × 48500 = 97000.
The lower limit will be 246300 - 97000 and the upper limit will be 246300 + 97000.
Lower limit = 246300 - 97000 = 149300
Upper limit = 246300 + 97000 = 343300
So 75% of the sales prices will be between $149,300 and $343,300
The complete question is:
The average sale price of new one-family houses in the United States for 2003 was $246,300. Using Chebyshev's theorem, find the range of values in which at least 75% of the sale prices will lie if the standard deviation is $48,500. Hint: You should memorize that when k is 2, it is 75% and when k is 3 it is 88.89%. Please answer with whole numbers: ex. 55,232 to 65,450 with commas

Sam made 60 gallons of paint by mixing 24
gallons of green paint with 36 gallons of blue
paint.
What part of every gallon is
from green paint?
Answer:
40% of every gallon is from green paint.
Step-by-step explanation:
Given that Sam made 60 gallons of paint by mixing 24 gallons of green paint with 36 gallons of blue paint, to determine what part of every gallon is from green paint the following calculation must be performed:
60 = 100
24 = X
24 x 100/60 = X
2,400 / 60 = X
40 = X
Therefore, 40% of every gallon is from green paint.

Solve for x: 3(x+6)=21. A)1 B) 5 C)9 D) 13
Answer:
[tex]\boxed {\boxed {\sf A. \ x=1}}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]3(x+6)=21[/tex]
We want to solve for x, so we must isolate the variable by performing inverse operations to both sides of the equation.
(x+6) is being multiplied by 3. The inverse of multiplication is division. Divide both sides of the equation by 3.
[tex]\frac {3(x+6)}{3}=\frac{21}{3}[/tex]
[tex](x+6)=\frac{21}{3}[/tex]
[tex](x+6)=7[/tex]
Now 6 is being added to x. The inverse operation of addition is subtraction. Subtract 6 from both sides of the equation.
[tex]x+6-6=7-6[/tex]
[tex]x=7-6[/tex]
[tex]x=1[/tex]
We can test our solution by plugging 1 in for x in the original equation.
[tex]3(x+6)=21[/tex]
[tex]3(1+6)=21[/tex]
[tex]3(7)=21\\21=21[/tex]
This checks out (21 is equal to 21) so we know our answer is x=1.
Answer:
A. X=1Step-by-step explanation:
To solve this problem, you have to use the distributive property.
Isolate the x from one side of an equation.
Distributive property:
[tex]\sf{A(B+C)=AB+AC}[/tex]
First, divide by 3 from both sides of an equation.
[tex]\dfrac{3(x+6)}{3}=\dfrac{21}{3}[/tex]
Solve.
21÷3=7
Rewrite the problem down.
x+6=7
Then, subtract by 6 from both sides.
[tex]\sf{x+6-6=7-6}[/tex]
Solve.

is 120,110,105… a geometric sequence
Answer: No
Step-by-step explanation:
Look at the 3 numbers in the sequence,
Geometric sequence means the ratio between two consecutive numbers in the sequence is a constant (eg. 10, 5, 2.5 is a geometric sequence as the ratio is a constant at 1/2)
However, for the sequence listed above
Looking at 1st and 2nd term,
Ratio = 110/120 = 11/12
Looking at 2nd and 3rd term,
Ratio = 105/110 = 21/22 which is not the same as 11/12.
Hence, since the ratio is not the same, this sequence is not a geometric sequence.

How does probability work?fundamentals of probability A probability is a numerical representation of the likelihood or possibility of an event occurring. Probabilities can be expressed as proportions with a 0–1 range or as percentages with a 0%–100% range.
Here,
The likelihood that one of the 68 seniors graduating this year will have their birthday coincide with graduation day is given here.
As a result, this issue can be modeled using a binomial probability model with a success chance of 1/365.
Given: The likelihood of exactly 1 success after 68 attempts.
=> P(x=1) = 68!/ (68-1)! * 1/365
=> 68/365
