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.

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

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].

Consider angle θ in Quadrant ll, where cos θ= -12/13. what's the value of sin θ
Answers
Answer:
5/13
Step-by-step explanation:
According to SOH CAH TOA
cos theta = adj/hyp = -12/13
Get the opposite using pythagoras theorem
13^2 = (-12)^2 + opp^2
169 = 144 + opp^2
opp^2 = 169-144
opp^2 = 25
opp = 5
Get sin θ
sin θ = opp/hyp
sin θ = 5/13
hence the value of sin θ is 5/13
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

Answer: 2520ft
Answers
Answer:
2520ft
Step-by-step explanation:
Calculation for what is the scale of the model?
Let x will be the span length
Hence,
x= 4200 feet long/20 inches long
x=210
Thus:
1 inch = 210 ft
1 ft = 2520
=2520ft
Therefore the scale of the model will be 2520ft
