Problem Solving

Semenov [28]

Answer:

12:30PM

Step-by-step explanation:

Known information:

There are 4 classes.

Each class is 1 hour.

There are 10 minutes between classes, like a break.

Draw a diagram:

start-CLASS1, break, CLASS2, break, CLASS3, break, CLASS4-end

There are 3 breaks because there are no breaks before and after the first and last classes.

Multiply the number of classes by the time length for class.

Multiply the number of breaks by the time length for breaks.

Add the two numbers together to get the total school time:

Classes: 4*1h = 4h

Breaks: 3*10min = 30min

4h + 30min = 4h 30min

Calculate 4h and 30min after 8:00 AM.

Add 4 hours and 30 minutes to 8.

. 8:00

+ 4:30

. 12:30

In the AM/PM clock (not 24 hour clock) there are 12 hours. After 12:59, it becomes 1:00, not 13:00.

Since "12:30" is possible on the AM/PM, we do not need to fix it.

The AM/PM clock changes at 12:00.

This means that after 11:59PM it becomes 12:00AM.

After 11:59AM it becomes 12:00PM. (Usually lunch)

Since 12:30 passed 11:59, the AM/PM sign changes.

The fourth class ends at 12:30PM.

Help pls properties of equality

Colt1911 [192]

For given equations, the reason/properties are:

equation steps properties/reason

1. m/-3 + 10 = -1 Given

2. m/-3 = -11 subtract 10 from each side

3. m = 33 multiply each side by -3

equation steps properties/reason

1. (5y - 1)/2 = 7 Given

2. 5y - 1 = 14 multiply each side by 2

3. 5y = 15 add 1 on both the sides

4. y = 3 divide each side by 5

In this question, we have been given two equations.

We need to state the reason foe each step.

Consider equation (2),

m/-3 + 10 = -1 ..............(Given)

m/-3 = -11 .....................(subtract 10 from each side)

m = 33 ....................(multiply each side by -3)

Now, consider equation (3),

(5y - 1)/2 = 7 ..........Given

5y - 1 = 14 ............multiply each side by 2

5y = 15 ..............add 1 on both the sides

y = 3 ..................divide each side by 5

Therefore, for given equations:

equation steps properties/reason

1. m/-3 + 10 = -1 Given

2. m/-3 = -11 subtract 10 from each side

3. m = 33 multiply each side by -3

equation steps properties/reason

1. (5y - 1)/2 = 7 Given

2. 5y - 1 = 14 multiply each side by 2

3. 5y = 15 add 1 on both the sides

4. y = 3 divide each side by 5

HELP me with These questions

Feliz [49]

Answer: 13.96 in²

Step-by-step explanation:

radius (r)

d = 2r

16 = 2r

8 = r

angle in radians (θ)

$\frac{180}{\pi} =\frac{25}{\theta}$

180(θ) = 25(π)

θ = $\frac{25}{180}\pi$

θ = $\frac{5}{36}\pi$

Area (A)

A = $\frac{1}{2}$ r² θ

= $\frac{1}{2}(8)^{2}(\frac{5}{36}\pi)$

= $\frac{40}{9}\pi$

= 13.96

Answer: 12π

Step-by-step explanation:

s = rθ

= 60 $(\frac{\pi }{5})$

= 12π

*************************************************************************

Answer: 22.440 cm²

Step-by-step explanation:

A = $\frac{1}{2}$ r²θ

= $\frac{1}{2}$ (10)² $(\frac{\pi} {7})$

= $\frac{50}{7}\pi$

= 22.440

*************************************************************************

Answer: 270°, 630°, -450°, -810°

Step-by-step explanation:

positive: -90 + 360 = 270

270 + 360 = 630

negative: -90 - 360 = -450

-450 - 360 = -810

*************************************************************************

Answer: $\frac{3\pi} {4}$

Step-by-step explanation:

$\frac{19\pi} {4} - 2\pi$

= $\frac{19\pi} {4} - \frac{8\pi} {4}$

= $\frac{11\pi} {4}$

$\frac{11\pi}{4} - 2\pi$

= $\frac{11\pi} {4} - \frac{8\pi} {4}$

= $\frac{3\pi} {4}$

If you subtract another 2π, you will end up with a negative value. The question asks for the smallest positive value.
