In △ABC, m∠B = 90°, m∠C = 15°, M ∈
BC. If m∠BAM = 60°, AM = 10 in. Find: AB
URGENT
Answer:
Step-by-step explanation:
You end up with a 30°-60°-90° triangle inside of △ABC.
The sides of a 30°-60°-90° triangle are always in the ratio 1:√3:2.
AB is opposite the 30° angle. AM is opposite the 90° angle and has length 10, so AB is half the length of AM.
AB = 5 units.
2. Which equation can be used to determine what number, n, is 40% of 64?
0(40) (64) = n
040 : 64 =n
00.40(64) =n
O 64n = 0.40
Rewrite the percent as a decimal and multiply by 64
The answer is: 0.40(64) = n

The 24/7 Truck Rental Company has been charging an initial rental fee of $29 plus $2.50 per hour for rental of their small trucks. After a change in pricing policy, the new fee will be $19 up front plus $3.25 per hour. After how many hours of renting the truck will the new plan be more expensive than the old plan
Answer:
14 hours
Step-by-step explanation:
Old plan :
Initial fee =. $29
Hourly fee = $2.50
New plan :
Initial fee = $19
Hourly fee = 3.25
Let number of hours = x
When new plan will be more expensive than old plan :
19 + 3.25x > 29 + 2.50x
3.25x - 2.50x > 29 - 19
0.75x > 10
x > 10 / 0.75
x > 13.3333

The probability of randomly selecting a daisy from Bouquet Sis 50% The probability of randomly selecting a daisy from Bouquet Tis 20% The probability of randomly selecting a daisy from Bouquet S is equal to the probability of randomly selecting a daisy from Bouquet T. The probability of randomly selecting a daisy from Bouquet S is less than the probability of randomly selecting a daisy from Bouquet T. PLS HELP ASAP
Answer:
The probability of selecting a daisy from S is less than the probability of selecting a daisy from T.
Step-by-step explanation:
The probability of selecting a daisy from S is 6/30=20%.
The probability of selecting a daisy from T is 6/12=50%
The probability of selecting a daisy from S is not equal to the probability of selecting a daisy from T.
The probability of selecting a daisy from S is less than the probability of selecting one from T.
You are choosing between two health clubs. Club A offers membership fee of $16 plus a monthly fee of $23. Club B offers membership for a fee of $20 plus a monthly fee of $21. After how many months will the total cost of each health club be the same? What will be the total cost for each club?
Answer:
After five months, the total cost would be the same.
Step-by-step explanation:
You'd have to write equations for the price per month for each club.

Explain why a regular polygon cannot have an interior angle that is 40°.
Answer:
Explained below.
Step-by-step explanation:
The formula for the interior angle of any regular polygon is given as;
Interior Angle = 180(n - 2)/n
Where n is number of sides
We are told the interior angle is 40°
Thus;
180(n - 2)/n = 40
Cross multiply to get;
180n - 360 = 40n
180n - 40n = 360
140n = 360
n = 360/140
n = 2.57
Number of sides of a regular polygon cannot be in decimal nor can it have less than 3 sides.
Thus, a shape with interior angle of 40 cannot be a polygon.
There is no regular polygon that has just 2 sides, therefore, a regular polygon cannot have an interior angle that is 40°.
The sum of all the interior angles of a regular polygon is given as, (n - 2)180.
Thus, assuming an interior angle is 40°, thus, let's find out if there is any regular polygon that has an interior angle that measures 40° using the formula, (n - 2)180.
Thus:
(n - 2)180 = 40
Solve for n180n - 360 = 40
180n = 40 + 360
180n = 400
Divide both sides by 180n = 400/180
n = 2.22
Thus, there is no regular polygon that has just 2 sides, therefore, a regular polygon cannot have an interior angle that is 40°.

a bag contains 6 white marbles and 4 black marbles. a marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw, followed by a white marble on the second?
Answer:
30/90 or 1/3
Step-by-step explanation:
This is because we know that 6+4=10. So we know the odds of drawing a white marble first is 6/10. And if we draw one without replacing it. This makes the second time 5/9 for white and 4/9 for black. We can then multiply 6/10 by 5/9 and get 30/90 which is equal to 1/3.
Hope this helps!

Assume that when adults with smartphones are randomly selected, 44% use them in meetings or classes. If 8 adult smartphone users are randomly selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.
Answer: The probability is 0.448
Step-by-step explanation:
First, 44% of adults use their smartphones in meetings or classes, then the probability that a random adult uses their smartphone on a meeting is:
p = 0.44
Then the probability that a random adult do not use it is:
q = 1 - 0.44 = 0.66
If 8 adult smartphone users are randomly selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.
For a random (and fixed) case, the probability will be equal to the product of the individual probabilities for each person, this leads to:
P = (0.44)*(0.44)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)
P = (0.44)²*(0.66)⁶ = 0.016
And now we need to consider the different combinations. If we have C combinations, then the probability for the event will be C*P.
Remember that if we have N elements, the total number of different groups of K elements (from these N elements) is:
[tex]C(N,K) = \frac{N!}{(N - K)!*K!}[/tex]
In this case, we have N = 8, and K = 2
Then we get:
[tex]C(8, 2) = \frac{8!}{(8 - 2)!*2!} = \frac{8!}{6!*2!} = \frac{8*7}{2} = 4*7 = 28[/tex]
Then there are 28 different combinations.
This means that the probability is:
Probability = 28*P = 28*0.016 = 0.448
Probability = 0.448
