This is an incredibly beautiful problem! It is solved mostly by algebra. r = 1 and the height will therefore be 2
Equations
l^2 + r^2 = l^2
l is the slant height.
Solution
SA = π * l * r + π r² = π(1 + √5) Divide both sides by π
Find l
l * r + r^2 = 1 + √5
l^2 = r^2 + h^2
l^2 = r^2 + (2r)^2
l^2 = 5r^2
l = √5 * r
Now go back to this equation to find r
l * r + r^2 = 1 + √5 Substitute the value for l
√5 r * r + r^2 = 1 + √5 On the left pull out r^2
r^2 (1 + √5) = 1 + √5 Divide by 1 + √5
r^2 = 1 Take the square root on both sides
sqrt(r^2) = sqrt(1)
r =1
Therefore h = 2
Volume of the cone.
V = 1/3 * π r² h
V = 1/3 * π 1² 2
V = 2/3 * pi

A car travels 72 miles on 6 gallons of gas. At that rate, how much gas will it need to travel 204 miles?
Answers
Answer:
17 gallons
Step-by-step explanation:
First find how many miles it can travel with 1 gallon which would be 72÷6 = 12 So 1 gallon can takes it to 12 miles
Do 204÷ 12 = 17
Answer:
17 galloons
Step-by-step explanation:
72 Miles= 6 galloons
144 miles = 12 galloons
204 miles = 17 galloons
in every 12 miles is equivalent to 1 galloon of gas so basically when you divide 204 into 12 you will get 17. you need 17 galloons of gas

Joanna is driving 185 miles to visit her family. She drives 68 miles in the morning, stops for lunch, and then drives the rest of the distance. How many miles did she drive after lunch?
Use the variable m to represent the number of miles she drove after lunch.
Which equation represents this situation and its solution?
m + 68 = 185; m = 117
68m = 185; m = 17
m + 185 = 68; m = 117
185m = 68; m = 17
Answers
Answer:
The equation represents this situation and its solution are m + 68 = 185; m = 117 ⇒ A
Step-by-step explanation:
Let us solve the question
∵ Joanna is driving 185 miles to visit her family
∴ The total distance she is driving = 185 miles
∵ She drives 68 miles in the morning
∴ d[tex]_{M}[/tex] = 68 miles
∵ She stops for lunch and then drives the rest of the distance
∵ m represents the number of miles she drove after lunch
∴ d[tex]_{L}[/tex] = m miles
∵ d[tex]_{L}[/tex] + d[tex]_{M}[/tex] = the total distance she is driving
∴ m + 68 = the total distance she is driving
∵ The total distance she is driving = 185 miles
∴ m + 68 = 185
∴ The equation represents this situation is m + 68 = 185
→ To solve the equation subtract 68 from both sides
∵ 68 - 68 + m = 185 - 68
∴ m = 117 miles
∴ The solution is m = 117

Can someone tell me the slope ?
Answers
Answer:
slope = 4
Step-by-step explanation:
We can find the slope of a line when knowing 2 points by using the slope formula, [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of the first point, respectively. [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of the second point, respectively.
The two points we have are (2,8) and (0,0). So, in this case, [tex]x_1[/tex] = 2, [tex]y_1[/tex] = 8, [tex]x_2[/tex] = 0, and [tex]y_2[/tex] = 0. Let's substitute those values into the formula and solve to get the slope:
[tex]m =[/tex] [tex]\frac{0-8}{0-2}[/tex]
[tex]\frac{-8}{-2}[/tex]
[tex]4[/tex]
So, the slope is 4.

You must use digits 1 - 9 and only ONCE
