Find the total amount given the original price and tip rate. Round to the nearest cent if necessary. Original price: $41.32 Tip: 15%
Answer:
$6.20
Step-by-step explanation:
We can covert 15% to a decimal by moving the decimal point two places over.
15% = 0.15
41.32 X 0.15 = 6.198
6.198 ≈ $6.20
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Original price: $41.32
Tip: 15% = %6.189
Total amount = = Original price + Tip amount
The total amount is $47.509
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price: $41.32
Tip: 15%
Now,
The amount of the tip.
= 15% of 41.32
= 15/100 x 41.32
= $6.189
The total amount.
= Original price + Tip amount
= 41.32 + 6.189
= $47.509
Thus,
Original price: $41.32
Tip: 15% = %6.189
Total amount = = Original price + Tip amount
The total amount is $47.509

Notation and symbols for fractions cannot be introduced too soon .
Answer:
A fraction is a number consisting of one or more equal parts of a unit. It is denoted by the symbol a/b, where a and b≠0 are integers (cf. Integer). The numerator a of a/b denotes the number of parts taken of the unit; this is divided by the number of parts equal to the number appearing as the denominator b.

Explain.
If median are getting from " ( a + b ) ÷ 2 " . So :
.
Find b :
.
(a + b) ÷ 2 = Median
(17 + b) ÷ 2 = 18
17 + b = 18 × 2
17 + b = 36
b = 36 - 17
b = 19
.
In conclusion, the value of b is 19

Find a :
[tex] \frac{7 + a + 12 + 15 + 17 + 19 + 20 + 22 + 24 + 25}{10} = 17[/tex]

A right cylinder has a height of 8 inches and a volume of 100 cubic inches. Which measurement is closest to the radius, in inches, of the cylinder? B. C. 16 D. 50
Answer:
A
Step-by-step explanation:
volume of a cylinder:
[tex]V=\pi r^2h[/tex]
where r = radius and h = height
We are given the volume (V) and the height (h) and we need to find the radius (r).
To find the radius we are going to want to plug in the given values into the formula for volume of a cylinder and solve for r
so, * plug in given values *
[tex]400= \pi r^28[/tex]
Now we solve for r
step 1 take the square root of each side
[tex]\sqrt{400} =20\\\sqrt{\pi r^28} =\sqrt{\pi } 4*r\\[/tex]
now we have [tex]20=\sqrt{\pi } 4*r[/tex]
step 2 divide each side by sqrt (π) 4
[tex]\frac{20}{\sqrt{\pi } 4} =3.989 \\\\\frac{\sqrt{\pi } 4*r}{\sqrt{\pi } 4}=r\\[/tex]
we're left with r = 3.989
Finally we round to the nearest whole number and get that the answer is A.4

Answer:
The area of the composite shape is:
122.50 [tex]cm^{2}[/tex]Step-by-step explanation:
To find the area of composite shapes you can pull apart this in known shapes, in this case, a rectangle and a triangle. Taking into account this, we can find the rectangle area firstly:
Rectangle area = base * heightThe base of the rectangle is the measure from down (14 cm) and the height is the measure in the left side (7 cm), with these values we can replace the formula:
Rectangle area = base * heightRectangle area = 14 cm * 7 cmRectangle area = 98 [tex]cm^{2}[/tex]Now, to calculate the area of the remaining triangle, we must use the next formula:
Triangle area = [tex]\frac{base*height}{2}[/tex]Where the base would be equal to the left side of the shape (7 cm) and the height is the difference between the measurement in the top side and the measurement in the bottom side:
Height of the triangle = top side - bottom sideHeight of the triangle = 21 cm - 14 cmHeight of the triangle = 7 cmWe can replace in the formula:
Triangle area = [tex]\frac{7 cm * 7cm}{2}[/tex]Triangle area =[tex]\frac{49cm^{2} }{2}[/tex]Triangle area = 24.5 [tex]cm^{2}[/tex]By last, we must add the two values of the areas obtained:
Area of the composite shape = rectangle area + triangle area.Area of the composite shape = 98 [tex]cm^{2}[/tex] + 24.5 [tex]cm^{2}[/tex]Area of the composite shape = 122.5 [tex]cm^{2}[/tex]Find the length of the third side. If necessary, round to the nearest
tenth.

3) 12ac^14/b^3
4) 9ac^7/b^5
Answer:
its c
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First of all we can simplify the the first therm because a property of power says that we can simplify a power of power by multiply the exponents
a^4b^8c^2
For the same property 2c^5 becomes 8c^15
now we have
(a^4b^8c^2)(6a^3b)(8c^15)/4a^6b^12c^3
if we simplify the numbers we can obtain
(a^4b^8c^2)(6a^3b)(2c^15)/a^6b^12c^3
If we simplify the parameters we can obtain
12ac^14/b^3
What is the value of 95 - 10 + +2(141 - 7)?
Answer:
353
Step-by-step explanation:
95 - 10 + 2(141 - 7)
following PEMDAS we will do parenthesis first
95 - 10 + 2(134)
multiplication is next
95 - 10 + 268
addition and subtraction are interchangeable when using PEMDAS but you do whatever comes first. since it's subtraction first in this equation we will do 95 - 10.
85 + 268
now we are left with addition
85 + 268 = 353

A line passes through the point (10, -6) and has a slope of -3/2 write an equation in slope-intercept form for this line
Answer:
y = -3/2x + 9
Step-by-step explanation:
As we already know the slope, we just need to find the y-intercept.
To find the y-intercept, you have to plug the values of x and y into the equation.
y = -3/2x + b
-6 = -3/2(10) +b
-6 = -15 + b
9 = b
The equation is y = -3/2x + 9
