Solve the inequality -4<{(<---is greater than or equal to)}4(6y-12)-2y

Leni [432]

For this case we have the following inequality:

$-4$

We must clear "y", so, we have the following steps:

1st step:

Apply distributive property to the right side of the inequality:

$-4$

2nd step:

We add similar terms:

$-4$

3rd step:

We add 48 to both sides of the equation:

$48-4$

4th step:

We divide between 22 on both sides:

$\frac{44}{22}$

Thus, the result is given by: $y> 2$

A circle with area 9pi has a sector with a central angle of 60 degrees What is the area of the sector ?

belka [17]

Area of the sector is 4.71 sq units

Step-by-step explanation:

Step 1: Area of the sector = Area of the circle × (C/360) where C is the central angle.

Area of the sector = πr²(C/360) = 9π × 60/360

= 9 × 3.14 × 1/6

= 28.26/6 = 4.71 sq units

9. During the past week, Mr. Hamilton gave one quiz and one exam to his high school algebra class.

Kamila [148]

Missing Information:

It takes Mr. Hamilton 1/15 of an hour to grade one student’s exam and 1/30 of an hour to grade one student’s quiz.

Answer:

$Total\ Time = \frac{x}{10}$

Step-by-step explanation:

Given

$Exam = \frac{1}{15}hr$

$Quiz = \frac{1}{30}hr$

Required

Determine the time spent on x students

First, we need to determine the total time spent on 1 student

$Time = Exam + Quiz$

$Time = \frac{1}{15} + \frac{1}{30}$

Take LCM

$Time = \frac{2 + 1}{30}$

$Time = \frac{3}{30}$

$Time = \frac{1}{10}$

Next is to determine the total time on x students:

$Total\ Time = \frac{1}{10} * x$

$Total\ Time = \frac{x}{10}$
