a. The discount amount of the exercise machine is $3.39.
b. The exercise machine's sale price will be $561.61
What is a percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.
Since the exercise machine with an original price of $565 is on sale at 6% off. The discount will be:
= Discount percentage × Price
= 6% × $565
= $3.39
The exercise machine's sale price will be:
= Original price - Discount
= $565 - $3.39
= $561.61

A submarine is 75 feet below sea level. It descends another 25 feet every 10 seconds for 3 minutes. What integer represents the submarines current location?
The integer represents the submarine's current location is -525 feet
The initial position of submarine = 75 feet below sea level
The descending rate of submarine = 25 feet every 10 second
Total time = 3 minutes
One minute = 60 seconds
3 minutes = 180 seconds
Therefore number of 10 seconds period = 180 / 10
= 18
For each 10 second the submarine descend 25 feet
Total distance that submarine descend = 18 × 25
= 450 feet
The initial position of submarine = -75
Current position = -75 - 450
= -525 feet
Hence, the integer represents the submarine's current location is -525 feet

the sum of the digits of a three-digit number is 26. the number is multiplied by 7 , then by 11 , and finally by 13. how many times will the digit 9 occur in the final product?
1001 many times will the digit 9 occur in the final product.
First of all,
13×7 × 11 =1001
The result is 4 digit number and hence when multiplied by 3 digit number, it is resulting in the number repetition.
123× 1001 = 123123
445 × 1001 = 445445
Based on this logic we can assume that,
Any 02 digit number multiplied by 101 will result. For Example:99 × 101 = 9999
85× 101 = 8585
20 × 101 = 2020.
2. Any 3 digit number multiplied with 1001 will result in same pattern. for example:
123 × 1001 = 123123
997 × 1001 = 997997
500× 1001 = 500500

gianna has $760 to spend at a bicycle store for some new gear and biking outfits.assume all prices listed include tax
she buys a new bicycle for $356.46
she buys 2 bicycle reflectors for $10.01 each and a pair of bike gloves for $20.72
she plans to spend some of all of the money she has left to buy new biking outfits for $45.35 each
The number of outfits that Gianna can buy given her budget is 8.
How many outfits can she buy?The first step is to determine the total cost of the items bought so far
Total cost = price of the bicycle + cost of the bicycle reflectors + cost of the bike gloves
Cost of the bicycle reflectors = cost of one reflector x 2
Cost of the bicycle reflectors = $10.01 x 2 = $20.02
Total cost = $20.02 + $356.46 + $20.72 = $397.20
Amount that is left to buy the outfits = amount Gianna has - total cost
$760 - $397.20 = $362.80
Number of outfits she can buy = amount left / cost of one outfit
Number of outfits she can buy = $362.80 / $45.35
Number of outfits she can buy = 8

Substitute n = 2 into the above equation,
a₂ = a₂₋₁ + 5
a₂ = a₁ + 5
Substitute a₁ = -12 into the above equation,
a₂ = -12 + 5

A furniture maker uses the specification 19.8≤w≤20.2 for the width, w, in inches of a desk drawer. Write the specification as an absolute value inequality.
Answer:
Step-by-step explanation:
The correct answer is:
|w-20| ≤ 0.12.
Explanation:
We first find the average of the two ends of the inequality:
(19.88+20.12)/2 = 40/2 = 20
This will be the number subtracted from w in the inequality.
Now we find the difference between this value and the ends:
20-19.88 = 0.12
20.12 - 20 = 0.12
This will be what our absolute value inequality ends with; the "answer" part, so to speak.
Since this inequality is written in compact form, it must be an "and" inequality; this means the absolute value inequality must be a "less than or equal to."
This gives us
|w-20| ≤ 0.12
Martin has $30 and he makes $10 an hour mowing grass. His friend has $60 and makes $7 an hour babysitting. After how many hours will Martin have more money?
Martin will have more-money than his friend after babysitting for 10 hours
How to determine the relationship equation?The given parameters in the question are:
Martin
Initial amount = $30
Additional earnings = $10
His friend
Initial amount = $60
Additional earnings = $7
The equation that shows their total earnings is
y = Initial amount + Additional earnings * x
So, we have
Martins: y = 30 + 10x
His friend: y = 60 + 7x
When Martin has more money, we have
Martins > His friend
This gives
30 + 10x > 60 + 7x
Evaluate the like terms in the above inequality
3x > 30
Divide by 3
x > 10

Answer:
(b) -16
Step-by-step explanation:
You want the y-value that goes with x=17 on the line with slope -8/9 through point (-19, 16).
Point-slope equationThe point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
The line with slope -8/9 through point (-19, 16) will have the equation ...
y -16 = -8/9(x +19)
Y for x=17You want the value of y for x=17. We can find that by substituting x=17 into the above equation:
y -16 = -8/9(17 +19) = -8/9(36) = -32
Adding 16 gives the value of y:
y = 16 -32 = -16
The line passes through the points (-19, 16) and (17, -16).
