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].

Yes, the table does show a function. First, just by seeing that the y values are the same, this means that this is a perfectly horizontal line. Horizontal lines are functions, but vertical lines aren't. I suppose the ordered pairs are just (-2,5), (0,5), and (3,5)
A manufacturer of cell phone screens has found that 5 percent of all screens produced have defects. Let pd represent the population proportion of all cell phone screens with a screen defect, therefore pd=0.05. For the sampling distribution of the sample proportion of cell phone screens from this manufacturer with a screen defect for sample size 400, μpˆd=0.05. Which of the following is the best interpretation of μpˆd=0.05 ?
For a randomly selected cell phone screen from this population, the mean number of screen defects for the selected screen will be equal to 0.05.
For a randomly selected cell phone screen from this population, the mean number of screen defects for the selected screen will be equal to 0.05.
A
For every sample of size 400 from this population, the proportion of cell phone screens with a screen defect will be 0.05.
For every sample of size 400 from this population, the proportion of cell phone screens with a screen defect will be 0.05.
B
For all samples of size 400 from this population, the mean number of screen defects for the samples is 0.05.
For all samples of size 400 from this population, the mean number of screen defects for the samples is 0.05.
C
For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.
For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.
D
For all samples of size 400 from this population, the standard deviation of all resulting sample proportions of cell phone screens with a screen defect is 0.05.
Answers
Answer:
For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.
Step-by-step explanation:
College Board
Using the Central Limit Theorem, it is found that the correct option is:
C For all samples of size 400 from this population, the mean of all resulting sample proportions of cell phone screens with a screen defect is 0.05.
By the Central Limit Theorem, for a proportion p in a sample of size n, the mean of the sampling distribution of sample proportions is [tex]\mu = p[/tex], while the standard error is [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex
In this problem, the mean of the sampling distribution of sample proportions is 0.05, that is, the mean proportion of all samples, hence, the correct option is C.

What is the value of x in the solution to the this system of equations:
y=-1/2x + 2
y - 2x = -3
Answers
Answer:
x=2 and y=1
Step-by-step explanation:
hope this helps!
Answer:
x = 2
Step-by-step explanation:
For system of equations, you need to equal them to each other. First, you need to isolate y on one side of the equation in [tex]y - 2x = -3[/tex]
[tex]y = -3 + 2x[/tex]
Now, equal the equations to each other:
[tex]-\frac{1}{2}x + 2 = -3 + 2x[/tex]
Add [tex]\frac{1}{2} x[/tex] to both sides of the equation:
[tex]2 = -3 + (2x + \frac{1}{2}x) = -3 + (\frac{4}{2}x + \frac{1}{2}x) = -3 + \frac{5}{2} x[/tex]
Subtract add 3 to both sides of the equation:
[tex]5 = \frac{5}{2}x[/tex]
Divide [tex]\frac{5}{2}[/tex] on both sides of the equation. Remember: when you divide a fraction, you multiply by the reciprocal. See below:
[tex]\frac{2}{5} * 5 = x[/tex]
[tex]\frac{10}{5} = x[/tex]
[tex]x = 2[/tex]
Check your work:
[tex]-\frac{1}{2}(2) + 2 = -3 + 2(2)[/tex]

what single decimal multiplier would you use to increase by 14% followed by a 1% decrease?
Answers
Answer:
1.1286
Step-by-step explanation:
Increasing something by 14% is the same as taking 114% of it, and decreasing it by 1% is the same as taking 99% of it. 114% is 1.14 as a decimal, and 99% is 0.99 as a decimal, so multiplying the two together, we get the single decimal
1.14 · 0.99 = 1.1286
Assume the number 100.
100(1.14)=114
114(0.99)=112.86
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
A scale of the Golden Gate Bridge in San Francisco Bay has
a main span that is 20 inches long. If the main span of the
bridge is 4200 feet long, what is the scale of the model?
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

Answer:
[tex]\angle BDA = 72^{\circ}[/tex]
[tex]\angle DAB = 36^{\circ}[/tex]
[tex]\angle BDC = 108^{\circ}[/tex]
[tex]\angle BCD = 36^{\circ}[/tex]
[tex]\angle DBC = 36^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle ABD = 72^{\circ}[/tex]
Required
Determine the missing angles
Since AB = AD, then:
[tex]\angle ABD = \angle BDA[/tex] --- Base angles of an isosceles triangle
Hence:
[tex]\angle ABD = \angle BDA = 72^{\circ}[/tex]
[tex]\angle ABD + \angle BDA + \angle DAB = 180^{\circ}[/tex] --- angles in a triangle
[tex]72^{\circ} + 72^{\circ} + \angle DAB = 180^{\circ}[/tex]
[tex]144^{\circ} + \angle DAB = 180^{\circ}[/tex]
Collect Like Terms
[tex]\angle DAB = 180^{\circ} - 144^{\circ}[/tex]
[tex]\angle DAB = 36^{\circ}[/tex]
[tex]\angle BDA + \angle BDC = 180^{\circ}[/tex] --- angle on a straight line
[tex]72^{\circ} + \angle BDC = 180^{\circ}[/tex]
[tex]\angle BDC = 180^{\circ} - 72^{\circ}[/tex]
[tex]\angle BDC = 108^{\circ}[/tex]
Since ABC is isosceles, then:
[tex]\angle DAB = \angle BCD = 36^{\circ}[/tex] --- base angle of isosceles
[tex]\angle BCD = 36^{\circ}[/tex]
Lastly:
[tex]\angle BCD + \angle BDC + \angle DBC = 180^{\circ}[/tex]
[tex]36^{\circ} + 108^{\circ} + \angle DBC = 180^{\circ}[/tex]
[tex]\angle DBC = 180^{\circ} - 36^{\circ} - 108^{\circ}[/tex]
[tex]\angle DBC = 36^{\circ}[/tex]

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
