Answer 1

Answer:

288 I think

Step-by-step explanation:

24 hours each month. Each year has 12 months so 24x12=288

Answer 2

Answer:

288

Step-by-step explanation:

There are 12 months in a year, so you add 24 12 times.

24 plus 24 is 48

48 plus 24 is 72

72 plus 24 is 96

96 plus 24 is 120

120 plus 24 is 144

144 plus 24 is 168

168 plus 24 is 192

192 plus 24 is 216

216 plus 24 is 240

120 plus 24 is 244

244 plus 24 is 288

4. John is packing books into boxes. Each box can hold either 15 small books or 8
large books. He needs to pack at least 35 boxes and at least 350 books, Write a
system of linear inequalities to represent the situation

Answers

Answer:

Your system of inequalities is:

x + y ≥ 35

15x + 8y ≥ 350

Step-by-step explanation:

Let x = number of boxes of small books and let y = number of boxes of large books.

 Since John needs to pack at least 35 boxes:

 (number of boxes of small books) + (number of boxes of large books) (is at least) 35

x + y ≥ 35

Since John needs to pack at least 350 books:

 (number of small books packed) + (number of large books packed) (is at least) 350

(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350

15x + 8y ≥ 350

the newspaper's readers, how many readers does the newspaper have?

the newspaper has 1200 readers because if 60 people is only 5%

if you divide 95 by 5 it is 19. 19 times 60 equals 1140. 1140 plus 60 equals 1200. 5% of 1200 is 60.

Answer:

i believe the answer is 1200

Step-by-step explanation:

if you set up a proportion

60 over x equal to 5 over 100 and solve

you get the answer 1200.

What is the slope-intercept equation for the line below?

A) y = 5/4x - 4
B) y = 4/5x - 4
C) y = -4/5x - 4
D) y = -5/4x - 4​

Answers

Answer:

A) y = 5/4x - 4

Step-by-step explanation:

Slope-intercept formula

y = mx + b, where m = slope, b = y-intercept

Slope formula

m = (y2 - y1)/(x2 - x1)

Given points (on the graph)

(0, -4) and (4, 1)

Slope is:

m = (1 - (-4))/(4 - 0) = 5/4

y-intercept is

-4 as per the first point

So the line is:

y = 5/4x - 4

Correct answer option is: A) y = 5/4x - 4
