Answer: 11,700 times
Step-by-step explanation:
First find the number of seconds in 3 minutes 15 seconds.
Each minute is 60 seconds so 3 minutes would be:
= 3 * 60
= 180
Add the 15:
= 195 seconds
Lightning strikes more than 60 times per second so we shall use 60 times
= 60 * 195
= 11,700 times

Answer:
x=7∠GBD=112∠EFC=112Step-by-step explanation:
Here, we need to know about the concept of the alternate interior angle theorem. This says that the alternate interior angle of two parallel lines formed with one transversal is equal. For a more graphical explanation, please refer to the attachment below.
--------------------------------------------------------------------------
Given
∠GBD=4x+84
∠EFC=16x
m∠GBD=m∠EFC
Solve
4x+84=16x ⇔ Given
4x+84-4x=16x-4x ⇔ Subtract 4x on both sides
84=12x ⇔ Simplify
84/12=12x/12 ⇔ Divide 12 on both sides
x=7 ⇔ Simplify
Substitute the x value into each angle expression
∠GBD=4x+84=4(7)+84=28+84=112
∠EFC=16x=16(7)=112
Hope this helps!! :)

Answer:
~27.764982043070833894247682407876
Step-by-step explanation:
First, we can add 8+5.5+8 because of the two sides which are 8 and one that is 5.5. That is 21.5.
Then, we must find the diagonal edge. To do that, we can use the pythagorean theorem. It makes a triangle, so given that a^2+b^2=c^c, we can say that 3^2+5.5^2=c^c. Using a calculator, we can find the square root of 39.25, then add it to 21.5.

What is a stemplot?A stem-and-leaf display, also known as a stem-and-leaf plot, is a technique used to visualize the shape of distribution by displaying quantitative data in a graphical fashion, similar to a histogram.
For the given stemplot the number of students who took more than 45 minutes to complete their homework can be calculated by counting the number of observations that are more than 45.
Therefore, the observations that are more than 45 are 48, 49, 51, 53, 53, 53, 53, 55, 60, 60, and 60.
Hence, the number of students who took more than 45 minutes to complete their homework is 11.

Identify the slope and y-intercept of the graph of the equation.
Answer:
y = 1/3x - 2
Slope = 1/3
y- intercept = -2
Step-by-step explanation:
To find the slope and y-intercept, first put the equation in y = mx + b format, Where m is your slope and b is your y-intercept.
Step one: Subtract x from both sides
To translate x over to the right side of the equation, subtract x from both sides, leaving you with this equation:
x - x -3y = -x + 6; which simplifies to:
-3y = -x + 6
Step Two: Divide Every Term By Negative 3
To get y alone by itself we need to cancel out -3 on the right side of the equation, to do that you must divide every term by negative 3 leaving you with this equation:
[tex]\frac{-3}{-3}[/tex]y = [tex]\frac{-1}{-3}[/tex]x + [tex]\frac{6}{-3}[/tex]; which simplifies to:
y = 1/3x - 2
M, slope, = 1/3
B, y-intercept, = -2
Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 19)(0,19) and (3, 9728)(3,9728).
Answer:
y = 19*(8)^x
Step-by-step explanation:
We want to write an equation like:
y = a*b^x
That goes through the points (0, 19) and (3, 9728)
Then, when x = 0, we must have y = 19
Replacing those values in the equation we get:
19 = a*b^0 = a*1 = a
19 = a
Then the equation is:
y = 19*b^x
We also know that when x = 3, y = 9728
If we replace these values in the equation, we get:
9728 = 19*(b)^3
Let's solve this for b.
9728/19 = b^3
512 = b^3
∛512 = b = 8
Then the equation is:
y = 19*(8)^x

What is the probability of getting an even number of dots in tossing a dice once if the ratio of even number to an odd number is 4:7?
Answer:
The probability is 4/11
Step-by-step explanation:
Here, we want to get the probability of getting an even number
Using the given ratio, the total of the numbers is 4 + 7 = 11
The number of even numbers is 4
So the probability of getting an even number will be the number of even numbers divided by the total of the numbers
We have this as 4/11

Step-by-step explanation:
First I'll solve y + 1 = 3x - 12 for y.
y + 1 = 3x - 12 All you need to do for this first part is subtract 1 from both sides.
y = 3x - 12 - 1
y = 3x - 13
I'll use the point for x being 6, and x being 12.
3(6) - 13
18 - 13
5
y is 5 when x is 6. (6, 5)
3(12) - 13
36 - 12
y is 23 when x is 12. (12, 23)
The formula for slope is y2-y1/x2-x1
(23 - 5)/(12 - 6) Subtract 5 from 13, and then subtract 6 from 12.
18/6 Divide 18 by 6.
3
The slope to the line y + 1 = 3(x - 4) is 3, which is C.

1) Hank is looking to sell his motorcycle. He compiles these prices from the newspaper for bikes just like his
$2,000; $ 16,900; $15,100; $14,500; and $17,000. Is it more reasonable for Hank to use the mean or the
median to get a reasonable estimated price for his bike?
Answer:
The median
Step-by-step explanation:
If you look at the sample section of the 5 different prices, you can see that $2,000 is very far away from the rest of the prices, which range from $14,000 to $17,000. This $2,000 is an outlier, and is likely not accurate in predicting reasonable prices for Hank's bike, so it should not be a factor in his decision or contribute to the mean value.
Find the total force on a piston of diameter 3.25 in., if the pressure (P) exerted on it is 150 lb/sq.In. Use 3.14 for and round to the nearest 50 lbs.
Answer:
1244 Ibf(Pounds force)
Step-by-step explanation:
The formula for Total force on a piston when given the diameter of the bore area =
F = P × π × d²/4
P = 150 lb/sq.In
π = 3.14
d = 3.25 in
Hence,
F = 150 lb/sq.In × 3.14 × 3.25 in /4
= 4974.9375 ÷ 4
= 1243.734375 Ibf(Pounds force)
Approximately = 1244 Ibf(Pounds force)

Use the slash key ( / ) to indicate a fraction.
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
If this line is given to have a slope of 3/2, let us at least put it in standard form, substituting the point ( 7, 4 ) into the equation afterwards:
y = 3/2* x + b, provided b ⇒ y - intercept,
( 4 ) = 3/2 * ( 7 ) + b,
4 = 21/2 + b,
b = 4 - 10.5,
b = -6.5
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
Answer:

What would be the new coordinates of a point that starts at (5,9) and is dilated by a scale factor of 2 and then translated 3 up and 2 right?
Answer:
(12. 21)
Step-by-step explanation:
Given the coordinate (5, 9), if it is dilated by a factor of 2, the resulting coordinate will be expressed as;
P = 2(5, 9)
P = (2(5), 2(9))
P = (10, 18)
If it is now translated 3 up and 2 right, then the final coordinate will be at;
P' = (10+2, 18+3)
P' = (12, 21)
Hence the final image will be at (12. 21)
Hunter assumed he would only get 54
problems correct on his test, but he
actually got 78 correct. What was his
percent error?
Hint: Percent error = | Prediction - Actual
x 100
| Actual
Round to the nearest percent.
[ ? ]%
Answer:
Percent error is 44.4%
Step-by-step explanation:
Here, we want to get the percent error
From the question, prediction is 54 while actual value is 78
from the formula given;
Percent error = |prediction-actual|/actual * 100%
so we have
|54-78|/54 * 100%
= 24/54 * 100% = 44.4%
