Answer:

The area of the composite shape is:

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:

The 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:

Now, to calculate the area of the remaining triangle, we must use the next formula:

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:

We can replace in the formula:

By last, we must add the two values of the areas obtained:

Step-by-step explanation:

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

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

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

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

84 divided by 6 = 14

Answer:

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

Answer:

slope

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Since m is the coefficient of the x- term, then

The coefficient of the x- term gives the slope

Answer:

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

.

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

Find a :

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