Total area of canvas used in the cunstruction of the tent = 551 - 1 = 550 meters square.
Area of a cone = πr(r + sqrt(h^2 + r^2))
22/7 * 7(7 + sqrt(h^2 + 7^2)) = 550
7 + sqrt(h^2 + 49) = 550/22 = 25
sqrt(h^2 + 49) = 25 - 7 = 18
h^2 + 49 = 18^2 = 324
h^2 = 324 - 49 = 275
h = sqrt(275) = 16.58
The volume of the tent is the volume of a cone with base radius of 7 meter and height of 16.58 meter.
Volume of a cone = 1/3 πr^2h
= 1/3 * 22/7 * 7^2 * 16.58 = 851.3 m^3
X is 1 because if you times it by x it equals it number
Answer:
13 1/3 cups
Step-by-step explanation:
The ratio of flour to dozens of cookies is 4:3 or 1 1/3:1
1 1/3 x 10 = 13 1/3
Rather than trial and error, you can do this with an equation.
x + x+1 + x+2 = 267 =>
3x+3 = 267
x = 264/3 = 88
So the numbers are 88+89+90. 90 is the largest number.
Answer:
1. A. (3,-2)
2. D. (-4,3)
3. (4,-2)
4. B. 3 cars
5. B. -10x7y2
Step-by-Step Explanation:
1. Graph the problem next time and to solve it, you just write the point where the intersect.
2. Write the second equation into the first one by substituting the y with the second equation: -3x-3(-5x-17)=3
3. Tbh its easier to just graph this one too and find the intersect point.
4. After reading the problem you should come up with the equations 5x+45y=195 and x+y=7 with x representing the number of cars and y representing the number of buses. All you have to do is substitute them into each other like in problem 2.
5. Multiply 12 and -5/6, then multiply the variables x^4 with x^3 y^2. All you have to do is add the exponent numbers together.
