The height of a triangle is increasing at a rate of 3 cm/min while the area of the triangle is increasing at a rate of 11 square cm/min. At what rate is the base of the triangle changing when the height is 5 centimeters and the area is 10 square centimeters
Answers
Answer:
2cm/minStep-by-step explanation:
The Area of a triangle is expressed as:
A = 1/2 bh
b is the base of the triangle
h is the height of the triangle
Given
dh/dt = 3cm/min
dA/dt = 11cm²/min
height h = 5cm
Area = 10cm²
Get the base first
10 = 1/2b(5)
20 = 5b
b = 20/5
b = 4cm
Differentiating the area with respect to time
A(b, h) = 1/2 bh
According to product rule
dA/dt = 1/2{b dh/dt + h db/dt}
Substitute the given parameters and get db/dt
11 = 1/2{4(3)+5db/dt}
11 = 1/2{12+5 db/dt}
11 = 6 + 5/2 db/dt
11-6 = 5/2 db/dt
5 = 5/2 db/dt
1 = 1/2 db/dt
cross multiply
2 = db/dt
db/dt = 2cm/min
Hence the rate at which the base of the triangle is changing id 2cm/min
2) Major league baseball salaries averaged $3.26 million with a standard deviation of $1.2 million in a certain year in the past. Suppose a sample of 100 major league players was taken. What was the standard error for the sample mean salary
Answers
Answer:
Standard error for the sample = $0.12 million
Step-by-step explanation:
Given:
Mean = $3.26 million
Standard deviation = $1.2 million
Number of sample = 100
Find:
Standard error for the sample
Computation:
Standard error for the sample = Standard deviation / √Number of sample
Standard error for the sample = 1.2 / √100
Standard error for the sample = $0.12 million

3. Aimee bought 9.8 meters of Geena satin cloth. One-fifth of the cloth was damaged by rats and the rest was
used to make 7 similar blouses.
A. How much cloth did she use for each blouse?
B. If she sold each blouse for P 178.25, how much money would she receive in all?
Answers
Answer:
a, 1.12m
b, P 1257.75
Step-by-step explanation:
A,
9.8m × 4/5 = 7.84m
7.84m ÷ 7 = 1.12m
B,
7 × 178.25 = P1247.75
We are required to find how much cloth she used for each blouse
cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75
Total quantity of geena satin bought = 9.8 meters
Quantity damaged by rat = 1/5 of 9.8 meters
= 0.2 × 9.8
= 1.96 meters
Total cloth used for 7 blouse = Total quantity of geena satin bought - Quantity damaged by rat
= 9.8 meters - 1.96 meters
= 7.84 meters
Cloth used for each blouse = Total cloth used for 7 blouse / 7
= 7.84 / 7
= 1.12 meters
Cost of each blouse = P 178.25
Total cost of 7 blouses = P 178.25 × 7
= P 1247.75
Therefore, cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75

We roll two dice. Find the conditional probability that at least one of the numbers is even, given that the sum is 8.
Answers
Answer:
0.599 or 0.6
Step-by-step explanation:
We will be using the alphabets M and N in this solution.
Let M be that one of the number is even
Let N be that the sum is 8
The sample space of these two dice when rolled is 36
Probability of 8 and even numbers is (4,4),(6,2),(2,6)
= 3/36 = 0.08333
Probability of sum of 8 is (4,4),(5,3)(3,5),(6,2),(2,6)
= 5/36 = 0.1389
P(M|N) = 0.08333/0.1389
= 0.599

If you copy a document on a​ machine, you should get a similar copy. Suppose you want to reduce a document to of its original size and you first reduce it by ​%. By what percent do you need to reduce the copy to obtain the desirable​ size?
Answers
Answer:
the numbers are missing, so I looked for a similar question:
If you copy a document on a machine, you should get a similar copy. suppose you want to reduce a document to 1/6 of its original size, and first reduce it by 25%. By what percent do you need to reduce the copy to obtain the desirable size?
You want the copy to be 1/6 of the original size = 16.67%
Since you first reduced the copy by 25%, the image is now 75% of its original size. In order to finally obtain a copy that is 16.67% of the original size, you must reduce this second copy by 1 - (16.67%/75%) = 77.78% ≈ 78%.
we can check our answer:
size of second copy x (1 - reduction)
0.75 x (1 - 0.7778) = 0.1667

Do 1.7 and 1.700 have the same value? In a full sentence, explain why or why notw
Answers
Answer: Yes
1.7 and 1.700 have the same value because zeros have no value, and without the zeros, 1.700 would turn into 1.7. It is not like there is another number that is not zero after the two zeros either.
Because 1.7 will still be call one point seventy even though it does have 0 ( also can say one point seven ) however if it was 1.07 it would be smaller than 1.7 ( 1| 07 < 1| 7 or 1| 70 )

Step-by-step explanation:
5. A turtle dives towards deeper water at a rate of 8 inches per second. It continues for a total of 16 seconds.
Which expression represents this situation?
We are given Maya's diving rate as:
8 inches per second
Because she is diving, the rate carries a negative sign hence, the expression of the situation is:
16 × -8
= 16(-8)
Option A 16(-8) is correct
6. Marisa has $26 in her purse. She pays $5 for lunch. Which expression represents this situation?
Amount she has =$28
She pays = $5
Hence, $26 + (-$5)
= $26 - $5
Option C. 26 + (-5) is correct
7. Aaron turned on his air conditioning and the temperature in his apartment decreased 6 degrees.

Answers
Answer:
m : ____ $4 ______ - $1
P(m) : __ 0.167 ____ 0.833
Step-by-step explanation:
Given that:
Fair dice is rolled once;
Winning = $4, if output is 6
If otherwise ; winning = - $1
M = amount of money won :
Distribution of M:
The amount of money won (M) is either :
$4 or - $1
Distribution of M:
Possible outcome : {1, 2, 3, 4, 5, 6}
P(winning $4) = P(rolling a 6)
