Answer:
Perimeter is (width×height) but in this case it would be base×width & height...
First find the with of the triangle,by measureing the points with the base.
Second to find the base simply look equilateral and the half circle. and see how the lines in between it and the triangle collide. and count the spaces to find the base.
Third measure the height with the best estimate.
And finally, multiply by (h×w) and divide by the base.

Answer:
42,84
Step-by-step explanation:
Remark
Two of the sides are 12 inches. The third side is also 12 but it serves as a diameter of the semicircle.
The circumference of the semi circle is 2*pi*r /2 = pi * r
The total perimeter is pi * r + 2*12
r = d/2
r = 12/2
r = 6
Perimeter = 6*pi + 24 might be you answer.
Perimeter = 42.84
I don't know which answer to use. It all depends how other questions have been answered. Sometimes you take the decimal answer and sometimes you take the answer in terms of pi. I think the latter is what I would try first.
Assume that the probability of a defective computer component is 0.02. Components arerandomly selected. Find the probability that the first defect is caused by the seventh componenttested. Find the expected number and variance of the number of components tested before adefective component is found.
Answer:
0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.
The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.
Step-by-step explanation:
Assume that the probability of a defective computer component is 0.02. Components are randomly selected. Find the probability that the first defect is caused by the seventh component tested.
First six not defective, each with 0.98 probability.
7th defective, with 0.02 probability. So
[tex]p = (0.98)^6*0.02 = 0.0177[/tex]
0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.
Find the expected number and variance of the number of components tested before a defective component is found.
Inverse binomial distribution, with [tex]p = 0.02[/tex]
Expected number before 1 defective(n = 1). So
[tex]E = \frac{n}{p} = \frac{1}{0.02} = 50[/tex]
Variance is:
[tex]V = \frac{np}{(1-p)^2} = \frac{0.02}{(1-0.02)^2} = 0.0208[/tex]
The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.
PLEASE HELP ASAPPPPP Find the value of x for mAB= 27° and mCD= 49°. The figure is not drawn to scale
Answer:
Step-by-step explanation:
The other guy has mislead other people. If i turned my thing in, I would have gotten a 90% instead of 100%.
It is A.
38 degrees.
The measure of x is (a) 38 degrees
The given parameters are:
[tex]mAB = 27^o[/tex]
[tex]mCD = 49^o[/tex]
The measure of x, is the average of angles AB and CD.
So, we have:
[tex]x = \frac{mAB + mCD}{2}[/tex]
Substitute known values of AB and CD in the above equation.
So, we have:
[tex]x = \frac{27^o + 49^o}{2}[/tex]
Add 27and 49
[tex]x = \frac{76^o}{2}[/tex]
Divide 76 by 2
[tex]x = 38^o[/tex]
Hence, the measure of x is (a) 38 degrees

Write an equation that represents a perpendicular line to y=-3x+5
Answer:
Example
Step-by-step explanation:
The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is 3 3 . The equation of a perpendicular line to y=3x−5 y = 3 x - 5 must have a slope that is the negative reciprocal of the original slope.

The ratio of blue cars to red cars in a garage is 9:7. If there are 49 red cars in the garage then how many blue cars must be in the
garage?
Answer:
Blue cars, B = 63 cars
Step-by-step explanation:
Let the blue cars be B.
Let the red cars be R.
Given the following data;
Ratio of B:R = 9:7 = 9 + 7 = 16
Red cars, R = 49
To find the number of blue cars;
First of all, we would determine the total number of cars using the expression;
R = 7/16 * x = 49
7x = 49 * 16
7x = 784
x = 112 cars
Now, we can find the number of blue cars;
B = 9/16 * 112
B = 1008/16
Blue cars, B = 63 cars

The Dakotas rented a minivan for their family vacation. When they returned
from vacation, the total bill for the van was $575. The standard weekly rate
from the rental company is $355 plus $55 for each additional day of usage.
How many additional days did the Dakotas have the minivan?
Answer:
4 additional days.
Step-by-step explanation:
So the total charge is $575.
It costs $355 for 1 week of use of the van.
1 week is 7 days.
It costs $55 for each extra day of use of the van.
575=55d+355
d is for the unknown extra amount of days.
subtract 355 from both sides
220=55d
divide by 55 on both sides
4=d
So, the Dakotas used the van for 4 additional days. So in total the used the van for 4+7 days.
4+7=11 total days.
But the answer to the question is 4 days, because it specifically ask for additional days.

Steven and his family ordered a meal the cost 136.50. Steven paid 14% sales tax and left a 20% tip on 136.50. What was the total cost
Answer:
The total cost was $182.91.
Step-by-step explanation:
Tax formula:
tax=tax percentage×amount
Tip formula:
tip=tip percentage×amount
solve
First find the tax. Write 14% as the decimal 0.14 before using it in the equation.
tax
= tax percentage×amount
= 0.14×136.50
= 19.11
The tax was $19.11.
Now find the tip. Write 20% as the decimal 0.20 before using it in the equation.
tip
= tip percentage×amount
= 0.20×136.50
= 27.3
The tip was $27.30.
Finally, find the total cost.
total cost
= cost + tax+tip
= 136.50+19.11+27.30
= 182.91
Answer:
182.91
