What is the lateral surface area of a cone that has a diameter of 7 inches and a slant height of 10 inches? A cone with diameter 7 inches and slant height 10 inches. L A = pi r l 12.25 pi inches squared 17.5 pi inches squared 35 pi inches squared 70 pi inches squared
Answers
Answer:
[tex]A=35\pi\ \text{inches}^2[/tex]
Step-by-step explanation:
Given that,
The diameter of a cone, d = 7 inches
Radius, r = 3.5 inches
The slant height of the cone, l = 10 inches
We need to find the lateral surface area of a cone. The formula for the lateral surface area of a cone is given by :
[tex]A=\pi rl[/tex]
Substitute all the values,
[tex]A=\pi\times 3.5\times 10\\\\A=35\pi\ \text{inches}^2[/tex]
So, the lateral surface area of the cone is [tex]35\pi\ \text{inches}^2[/tex].

Leo reads 14 pages in 1/2 hour. What is the unit rate for pages per hour? For hours per page?
Answers
Answer:
1:28 | 1:1/28
Step-by-step explanation:
We can show the first two numbers as a ratio:
14:1/2
But we want that second number to be 1 so we can multiply by 1:
28:1 <------ Pages per hour
But now we need the left to be 1, so we divide by 28:
1/28:1
Then flip:
1:1/28

solve the following systems of equations by elimination
- 2x - 5y=-27
- 2x + 3y = 13
Answers
Answer:
x= 1
y- 5
Step-by-step explanation:
okay so you know the rules...
we need to eliminate one variable to solve this system so first...
im going to get rid of x first to do so i need to...
multiply any of the equation by negative one to get it to a positive to eliminate
-2x - 5y= -27
( -2x + 3y= 13) -1
-2x -5y= -27
2x -3y= -13 follow the rules of signed integers
we eliminate x and have this left
-5y= -27
-3y= -13 use the second rule of elimination....add the rest up
-8y= -40 divide both sides by -8
y= 5
we arent done yet we need to find the other variable
plug in y to one of the equations like this...
-2x - 5(5)= -27
-2x - 25= -27 add -25 to both sides to get the variable by itself
-2x= -2 divide both sides by -2
x= 1
Hope this helped!
The half-life of the element radon (Rn86) is 3.8 days. In a sample originally containing 1 gram of radon, the amount of left over days is given by the model () = (0.5)t/3.8 a) How much radon will be present after 7.6 days? b) How much radon will be present after 10 days?
Answers
Answer:
a.0.25 g
b.0.16 g
Step-by-step explanation:
We are given that
Half-life of the element radon=3.8 days
Mass of sample of radon=1 g
The amount of radon left after t days is given by
[tex]A(t)=(0.5)^{\frac{t}{3.8}}[/tex]
a.
We have to find the amount of radon left after 7.6 days.
Substitute t=7.6 in the equation
Then, we get
[tex]A(7.6)=(0.5)^{\frac{7.6}{3.8}}[/tex]
[tex]A(7.6)=0.25 g[/tex]
Hence, the amount of radon will be present after 7.6 days=0.25 g
b. We have to find the amount of radon left after 10 days.
Substitute t=10 in the equation
Then, we get
[tex]A(10)=(0.5)^{\frac{10}{3.8}}[/tex]
[tex]A(10)=0.16g[/tex]
Hence, the amount of radon will be present after 10 days=0.16 g

The map distance between Toledo and Columbus is 48 millimeters. What is the actual distance? The actual distance is ___ miles. Question 4 d. Cincinnati is about 225 miles from Cleveland. What is the distance between these cities on the map? On the map, the distance is ___ millimeters.
Answers
Answer:
The actual distance is 120 miles.
The distance between these cities on the map is 90 millimeters.
Step-by-step explanation:
Consider the figure shown below.
10 mm distance on the map is equal to 25 miles of actual distance.
10 mm = 25 miles
1 mm = 2.5 miles ...(1)
The map distance between Toledo and Columbus is 48 millimeters.
Multiply both the sides of the equation 1 with 48.
48×1 mm = 48×2.5 miles
48 mm = 120 miles
The actual distance is 120 miles.
Cincinnati is about 225 miles from Cleveland.
Divide 225 by 2.5
[tex]\dfrac{225}{2.5}=90[/tex]
Hence, the distance between these cities on the map is 90 millimeters.

B= 6
Step-by-step explanation:
pythagorean theorem formula is a² + b² = c²
so: 8² + b² = 10²
then: 64 + b² = 100
subtract 64 from both sides to get b²= 36
square root 36 and you get 6 for b
