Answer:

30.96 m^2

Step-by-step explanation:

Side length of the square is also the diameter of the semicircle so:

r = 0.5 * 12 m = 6 m

Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:

Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area

(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)

= 144 - 56.52 - 56.52

= 30.96 m^2

Work out m and c for the line: 3 y + 6 x = − 3

Usimov [2.4K]

Answer:

m is -2 and c is -1

Step-by-step explanation:

• Let's first phrase out the general equation of a line

${ \rm{y = mx + c}}$

m is the slope
c is the y-intercept

[ remember that a general line equation must be in slope - intercept form as shown above ]

• from our question, we are given the equation;

${ \rm{3y + 6x = - 3}}$

• let's make y the subject in order to make the equation in slope - intercept format.

→ remember to apply "subject making knowledge"

${ \rm{3y = - 3 - 6x}} \\ \\ { \rm{3y = - 6x - 3}} \\ \\ { \rm{ \frac{3y}{3} = \frac{ - 6x}{3} - \frac{3}{3} }} \\ \\ { \boxed{ \rm{y = - 2x - 1}}}$

• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c

${ \rm{m \: \dashrightarrow \: - 2}} \\ \\ { \rm{c \: \dashrightarrow \: - 1}}$

Pls help me ill mark branliest

Answer:

She shouldn't tip at all since that's a ridiculous concept

Step-by-step explanation:

common sense

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP

The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so

cost = price + 0.1*price

cost = 1.1 * price

price = cost / 1.1

price = 22 / 1.1 = 20

now we need 20% of that so that's

20 * 0.2 = 4

If she's simple-minded enough to tip that would amount to $4

A 6 inch personal pizza has 650 calories, with 240 of those from fat. A 14 inch pizza is cut into 8 slices. Estimate the number

professor190 [17]

Answer:

Number of calories in one slice of a 14 inch pizza is 189.825. 

Step-by-step explanation:

Given that 6 inch pizza has 650 calories. 

Therefore 1 inch pizza has $\frac{650}{6}$ calories. 

14 inch pizza will have

$\frac{650}{6} \times 14=216.67 \times 14=1516.66 \ calories$

Given that the 14 inch pizza is divided into 8 slices.

Therefore each slice of the 14 inch pizza will have

 $\frac {1516.66}{8} =189.825 calories$

Unit 4 mid

HACTEHA [7]

None of these lines are parallel or perpendicular. I assume you may have mistyped the original equation. If the original equation had a 4 next to the x instead, then the following is true.

The first is parallel
The second is neither
The third is perpendicular.
