Swim flippers are helpful for scuba
diving. You can rent them daily for
$15 per day, plus 8% tax. How
much will it cost, including tax, to
rent them for three days?
Answer:
The answer would be $48.60.
Step-by-step explanation:
Some people could probably answer it better but here's my way: When you have a percentage of something you bring it to the decimal. 8% would be 0.08. We take this and multiply it by the cost: 0.08 times 15, giving us $1.2 per $15 dollars spent. 1.2 times the 3 days would be 3.6 and 15 times 3 is 45 together this would give you the grand total of $48.60.
The sum of 5 consecutive even numbers is 100 ples help :/
Consecutive even numbers are numbers that go in order, such as 1,2,3,4,5.
There are 5 even numbers.
They would be x, x+2, x+4, x+6, and x+8 (you add 2 each time so they are even).
Now when adding all these numbers, you get 100.
So there's your equation.
x+x+2+x+4+x+6+x+8=100
Add like terms.
5x+20=100
Solve for x.
5x=80
x=16
So the first number is 16.
The second is 18.
Third is 20.
Fourth, 22.
And fifth, 24.
You can add them to see if you are correct.
16+18+20+22+24=100
The numbers are 16,18,20,22, and 24.

Lucia measured the high school and made a scale drawing. The scale she used was 2 centimeters : 3 meters. The parking lot is 54 meters wide in real life. How wide is the parking lot in the drawing?
Answer: The parking lot in the drawing is 36 centimeters.
Step-by-step explanation:
Given: Actual width of parking lot = 54 meters
The scale she used was 2 centimeters : 3 meters.
i.e. 3 actual meters = 2 centimeters on drawing
⇒ 1 actual meter = [tex]\dfrac23[/tex] centimeters on drawing
⇒ 54 actual meters = [tex]54\times\dfrac23[/tex] centimeters on drawing
⇒ 54 actual meters = 36 centimeters
Hence, the parking lot in the drawing is 36 centimeters.

In triangle ABC, the measure of angle ABC is 51°
and ACB is a right angle. What is the measure of
angle BAC in degrees?
Answer:
39 degrees
Step-by-step explanation:
The sum of angle in the triangle ABC is a80 degrees
m<ACB + <BAC + <ABC =1 80
90 + <BAC + 51 = 180
141 + m<BAC = 180
m<BAC = 180-141
m<BAC = 39 degrees
Hence the measure of m<BAC is 39 degrees
In the figure, AB || CD. If m<1=70° and m<2 = 45°, find the m<3
Answer:65 degrees
Step-by-step explanation: a triangle has 180 degrees.
one angle is 45 degrees and the other is 70
if we add them together we get 115
180-115 is 65
m3 is 65 degrees

.5333333 repeating as a fraction
Answer:
The answer is 8/10
Step-by-step explanation:
When you convert a decimal into a fraction especially a repeating decimal it could be a little complicated but here is what you had to do to find that answer
Step 1: Let x equal the decimal number
Which is x = 0.533333
And with 1 digit in the repeating decimal group create a second equation by multiplying both sides by 10^1 = 10
Step 2:
10x = 0.5333333
Now subtract equation 1 from equation 2
which is
10x = 5.333333
x = 0.5333333
--------------------------
9x - 4.8
We get
9x - 4.8
Step 3: Solve for x
X = 4.8/9
Multiply to eliminate 1 decimal place.
Here you multiply top and bottom by 1 10's
= 10^1 = 10
4.8/9 x 10/10 = 48/90
Step 4: Find the Greatest Common Factor (GCF) of 48 and 90,
if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 6,
48 ÷ 6/90 ÷ 6 = 8/15
Step 5: Therefore
X = 8/15
And in conclusion
0.5333333 = 8/15
So 8/15 is the answer
Have a nice day!

The graph below shows a company's profit f(x), in dollars, depending on the price of pencils x, in dollars, sold by the company:
Graph of quadratic function f of x having x intercepts at ordered pairs negative 0, 0 and 10, 0. The vertex is at 5, 160.
Part A: What is an approximate average rate of change of the graph from x = 2 to x = 5, and what does this rate represent? (3 points)
Part B: Describe the constraints of the domain. (3 points)
Answer:
A. The maximum represents the most amount of pencil price in dollars sold for the most amount of profit and the x-intercepts represent the profit when it is. The intervals at where the function increases represents a bigger profit for a price, whereas a decreasing interval represents a lower profit for a price.
Step-by-step explanation:
my answer for my test
The average rate of a function is 20 and for every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
Average rate of a function:
= (160-100)/5-2
= 20
For every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.
Because prices are rarely negative, the domain is most likely confined to 0≤x. The price may be set so high that it yields a loss, but that is not a viable option. As a result, x ≤10 is the upper limit of the sensible domain.
Thus, the average rate of a function is 20 and for every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

The length of a rectangle is 3cm more than its width.If the area of the rectangle is 28cm^2,find the width.
Answer: The dimensions of the rectangle are 7 cm × 4 cm
Step-by-step explanation:
let,
Breadth of the rectangle (l) = x
Length of the rectangle (b) = x + 3
Area of the rectangle = 28 cm²
Area of the rectangle = l × b
⇒ (x) × (x + 3) = 28
⇒ x² + 3 x = 28
⇒ x² - 3 x - 28 = 0
⇒ x² - 7 x + 4 x - 28 = 0
⇒ (x - 7) + 4(x - 7) = 0
⇒ (x - 7)(x + 4) = 0
⇒ x = 4
Breadth = 4 cm
Length -
⇒ 4 + 3
⇒ 7 cm
