Answer:

$18

Step-by-step explanation:

15 x 15% = 2.25 This is the tip.

15 x 5% = 0.75 This is the tax amount.

ADD THEM ALL UP:

2.25 + 0.75 + 15 = $18

Answer: 18

Step-by-step explanation:

so the equation to use to find tip amount is meal price * (tip percent)

and to find sales tax amount, meal price * (sales tax percent)

so tip amount = 15 * (0.15) = 2.25

and the sales tax amount = 15 * (0.05) = 0.75

so to find the total, add meal price + tip amount + tax amount

= 15 + 2.25 + 0.75 = 18

The equation 201.50=f+6.50(21) represents the cost of printing the shirts at a second printing company. Find the solution to the

AveGali [126]

Answer:

f = 65

Setup cost = 65

Step-by-step explanation:

Given the equation : 201.50=f+6.50(21)

Solving for f:

201.50 = f + 136.50

201.50 - 136.50 = f

f = 65

The equation above is written in the form a slope intercept function where,, 6.50 is the gradient and X equals the number of shirts, The total cost of printing is 201.50

f is the intercept and represents the initial fee or setup cost. Hence, the setup. Cost = 65

What is slope and how do you find it??

lions [1.4K]

the formula for slope is

$\frac{(y2-y1)}{(x2-x1)}$

so just replace y and x for the proper values

How do you find the area of the shaded sector of the circle? The radius is 10in and the sector is 45 degrees

Step2247 [10]

Given:

Radius of the circle = 10 in

Central angle of the sector = 45 degrees

To find:

The area of the sector.

Solution:

Area of a sector is

$A=\dfrac{\theta}{360^\circ}\pi r^2$

Where, $\theta$ is the central angle in degrees.

Putting r=10 and $\theta=45^\circ$ , we get

$A=\dfrac{45^\circ}{360^\circ}\pi (10)^2$

$A=\dfrac{1}{8}\pi (100)$

$A=12.5\pi$

Therefore, the area of the sector is 12.5π sq. inches.

Help anyone can help me do this question 3,I will mark brainlest.

malfutka [58]

Answer:

see explanation

Step-by-step explanation:

Calculate the slopes between pairs of the 3 points using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 9, 3) and (x₂, y₂ ) = (- 3, 9)

m = $\frac{9-3}{-3-(-9)}$ = $\frac{6}{-3+9}$ = $\frac{6}{6}$ = 1

Repeat with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (- 3, 9)

m = $\frac{9-1}{-3-5}$ = $\frac{8}{-8}$ = - 1

If lines are perpendicular then the product of their slopes = - 1 , then

1 × - 1 = -1

Thus there is a right angle between the 2 lines

Then triangle is right- angled
