A pair of shoes that originally sold at $30 is now being offered at a 25% discount.
What is its present price?
Answer:
$22.5
Step-by-step explanation:
You will pay $22.5 for a item with original price of $30 when discounted 25%.
Answer:
Refer to explanation
Step-by-step explanation:
The screenshot you put is the correct answer, here's another method to get the same answer:
Find what 25% is.
100% = 30
1% = 30 ÷ 100 = 0.30
25% = 0.30 x 25 = 7.50
Find the price after the 25% discount.
100 - 25 = 75
75% = 30 - 7.50 = 22.50 or 0.30 x 75 = 22.50 (Both solutions give the same answer)
Last Friday Trevon had $29. Over the weekend he received some money for cleaning the attic. He now has $41. How much money did he receive?
A. 29 - n = 41
B. 29 - n = 40
C. 29 + n = 41
D. 29 + n = 40
Answer:
C
Step-by-step explanation:
Trevon started with $29.
After cleaning, his total rose to $41.
Since he received money, we add that amount (n) to his initial amount of money ($29), to equal his total amount ($41)

60 in scientific notation
Answer:
I think the answer would be 6.0x10¹
If 60 was in scientific notation it would look like 6.0 because there is only one zero and we would need to move the decimal one place to the right. So we multiply 10¹ so we can move that decimal to the right to make 60.

3. A manufacturing process produces integrated circuit chips. Over the long run, the fraction of bad chips produced by the process is 20%. Thoroughly testing a chip to determine whether it is good or bad is rather expensive, so a cheaper test is used. All good chips will pass the test, but so will 6% of the bad chips. a) (4 points) What is the probability that a randomly chosen chip will pass the test
Answer:
0.812 = 81.2% probability that a randomly chosen chip will pass the test
Step-by-step explanation:
Over the long run, the fraction of bad chips produced by the process is 20%.
So 100 - 20 = 80% are good.
All good chips pass the test, while 6% of the bad chips(20%) also pass.
a) (4 points) What is the probability that a randomly chosen chip will pass the test
[tex]p = 0.8 + 0.06*0.2 = 0.812[/tex]
0.812 = 81.2% probability that a randomly chosen chip will pass the test

The time of a pendulum varies as the square root of its length. If the length if a pendulum which beats 15seconds is 9cm, find the length that beats 80seconds and the time of a pendulum with length 36cm
Answer:
length= 3.7 ft.
Step-by-step explanation:
T= (square root of length) * k
1.8 seconds = (square root of 3) * k
k= 1.8 seconds / (square root of 3)
a.) T= (square root of 11) k
substituting k:
T=(square root of 11) * 1.8 seconds / (square of 3)
T= 3.4 seconds
b.) 2 seconds = (square root of length) k
substituting k:
2 seconds =(square root of length) 1.8 seconds / (square root of 3)
Divide the equation by 1.8 seconds / (square root of 3):
2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)
10(square root of 3) / 9 = (square root of length)
square both sides:
100/7 ft= length
length= 3.7 ft.
Hope this helps.
Can you find four examples that are true or a counterexample for the following statement?For every integer n, the value of n^2 + 1 is odd
Solving the expression, it is found a counterexample that when [tex]n = 1[/tex], [tex]n^2 + 1 = 2[/tex] is even.
----------------------
The expression given is:[tex]E(n) = n^2 + 1[/tex]
We want to test for every integer n, that E(n) is odd.----------------------
For n = 0:
[tex]E(0) = 0^2 + 1 = 0 + 1 = 1[/tex]
Odd number.
----------------------
For n = 1:
[tex]E(1) = 1^2 + 1 = 1 + 1 = 2[/tex]
Even, thus, this is the counterexample.
