Marina86 [1]

Answer:

Option A

Step-by-step explanation:

The area outside of the semicircle is the difference of the areas of the rectangle and the semicircle.

Area of rectangle:

A₁ = w(w + 5) = w² + 5w

Area of the semicircle:

A₂ = 1/2*πd²/4 = 1/8*πw²

The area we are looking for is:

A = A₁ - A₂
A = w² + 5w - 1/8πw²

Correct choice is A

The coordinate plane below represents a city.

alex41 [277]

Answer:

Part A) The system of inequalities is

$x\geq2$ and $y\geq2$

Part B) In the procedure

Part C) The schools that Natalie is allowed to attend are A,B and D

Step-by-step explanation:

Part A: Using the graph above, create a system of inequalities that only contain points C and F in the overlapping shaded regions

we have

Points C(2,2), F(3,4)

The system of inequalities could be

$x\geq2$ -----> inequality A

The solution of the inequality A is the shaded area at the right of the solid line x=2

$y\geq2$ -----> inequality B

The solution of the inequality B is the shaded area above of the solid line y=2

see the attached figure N 1

Part B: Explain how to verify that the points C and F are solutions to the system of inequalities created in Part A

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

Verify point C

C(2,2)

Inequality A

$x\geq2$ -----> $2\geq2$ ----> is true

Inequality B

$y\geq2$ ------> $2\geq2$ ----> is true

therefore

Point C is a solution of the system of inequalities

Verify point D

F(3,4)

Inequality A

$x\geq2$ -----> $3\geq2$ ----> is true

Inequality B

$y\geq2$ ------> $4\geq2$ ----> is true

therefore

Point D is a solution of the system of inequalities

Part C: Natalie can only attend a school in her designated zone. Natalie's zone is defined by y < −2x + 2. Explain how you can identify the schools that Natalie is allowed to attend.

we have

$y < -2x+2$

The solution of the inequality is the shaded area below the dotted line $y=-2x+2$

The y-intercept of the dotted line is the point (0,2)

The x-intercept of the dotted line is the point (1,0)

To graph the inequality, plot the intercepts and shade the area below the dotted line

see the attached figure N 2

therefore

The schools that Natalie is allowed to attend are A,B and D

The family size bottle of sunscreen holds 12121212 fluid ounces (fl oz)(\text{fl oz})(fl oz)(, start text, f, l, space, o, z, en

Musya8 [376]

Answer:

The regular bottle holds 9 fl oz less

Step-by-step explanation:

Given

Family Size = 12 fl oz

Required

Determine the size held less by the regular bottle

From the question, we have that the regular bottle holds 75% less;

$Regular\ Size = 75\% * Family\ Size$

Substitute 12 fl oz for Family Size

$Regular\ Size =75\% * 12\ fl\ oz$

Convert percentage to fraction

$Regular\ Size = \frac{75}{100} * 12\ fl \oz$

$Regular\ Size = \frac{75 * 12\ fl\ oz}{100}$

$Regular\ Size = \frac{900\ fl\ oz}{100}$

$Regular\ Size = 9\ fl\ oz$

Hence, the regular bottle holds 9 fl oz less
