The arena set-up team’s work schedule is shown in the table below. Convert the minutes worked into hours.

Sladkaya [172]

Answer:

$Mike\ Chewer = 14\frac{1}{2}\ hr$

$Jennifer\ Glass = 3\frac{3}{4}\ hr$

$Fred\ Carlton = 1\frac{1}{4}\ hr$

$Amy\ Amaretto = 12\ hr$

Step-by-step explanation:

Given

$Mike\ Chewer = 870\ minutes$

$Jennifer\ Glass = 225\ minutes$

$Fred\ Carlton = 75\ minutes\\$

$Amy\ Amaretto = 720\ minutes$

Required

Convert to hours (in fraction)

To do this, we simply divide the time by 60

$Mike\ Chewer = 870\ minutes$

Divide by 60

$Mike\ Chewer = \frac{870}{60}\ hr$

$Mike\ Chewer = \frac{87}{6}\ hr$

Express as mixed numbers

$Mike\ Chewer = 14\frac{3}{6}\ hr$

Simplify

$Mike\ Chewer = 14\frac{1}{2}\ hr$

$Jennifer\ Glass = 225\ minutes$

Divide by 60

$Jennifer\ Glass = \frac{225}{60}\ hr$

Express as mixed numbers

$Jennifer\ Glass = 3\frac{45}{60}\ hr$

Simplify

$Jennifer\ Glass = 3\frac{3}{4}\ hr$

$Fred\ Carlton = 75\ minutes\\$

Divide by 60

$Fred\ Carlton = \frac{75}{60}\ hr$

Express as mixed numbers

$Fred\ Carlton = 1\frac{15}{60}\ hr$

Simplify

$Fred\ Carlton = 1\frac{1}{4}\ hr$

$Amy\ Amaretto = 720\ minutes$

Divide by 60

$Amy\ Amaretto = \frac{720}{60}\ hr$

$Amy\ Amaretto = 12\ hr$

Graph the following system of linear inequalities. Identify at least two points in the solution: y < 5 - 2x | x + 5y > -7

romanna [79]

Answer:

(1,2) and (2,-1)

Step-by-step explanation:

we have

$y< 5-2x$ ----> inequality A

The solution of the inequality A is the shaded area below the dashed line $y=5-2x$

$x+5y>-7$ ---->inequality B

The solution of the inequality B is the shaded area above the dashed line $x+5y=-7$

The solution of the system of inequalities is the triangular shaded area between the two dashed lines

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area

Two points in the solution are(1,2) and (2,-1)see the attached figure

For questions 1-4 Find the missing triangle

Semenov [28]

Answer:

1. 51°

2. 40°

3. 65°

4. 60°

Step-by-step explanation:

The sum of the angles in a triangle is 180°. We can use the angles given to find the missing angle.

1. 51°

42+87+x=180

129+x=180

x=51

-------------------------------------------------------------------------------

2. 40°

110+30+x=180

140+x=180

x=40

-------------------------------------------------------------------------------

3. 65°

20+95+x=180

115+x=180

x=65

-------------------------------------------------------------------------------

4. 60°

60+60+x=180

120+x=180

x=60
