Answers

Answer 1

Given:

The given circle graph shows the number of hours a college student spends studying each subject.

To find:

Which subject gets 30% of the students study time?

Solution:

From the given circle graph, we get study time of following subjects:

Art = 10 hr

P.E. = 6 hr

History = 13 hr

English = 5 hr

Math = 9 hr

Total study time is:

[tex]10+6+13+5+9=43\ hr[/tex]

30% of 43 hr is:

[tex]43\times \dfrac{30}{100}=12.9[/tex]

[tex]43\times \dfrac{30}{100}\approx 13 \hr[/tex]

It means 30% of 43 hr is about 13 hr.

Since study time of History is 13 hr, therefore History gets 30% of the students study time.

Hence, the correct option is C.

Answer:

218.665

Step-by-step explanation:

Separate by shape, find the areas of the triangles first, so (10.1 x w)/2 To get the missing side you do 30.5-21.4=9.1. then divide that by 2 because you have 2 lines (triangles) that aren't part of the 21.4. After you find the area for the one triangle (10.1 x 4.55)/2=22.9775, multiply by 2 to get the combined area of both triangles. Next step is to find the area of the rectangle, which is just 21.4 x 30.5=216.14. Add all the areas, 45.955+216.14=262.095. Last step is to subtract the area of the shaded region, the rhombus, which is just diagonal x diagonal / 2. so (8.6 x 10.1)/2=43.43. 262.095-43.43=218.665.

Answer:

Step-by-step explanation:

1). 3x(2x - 2) = 3x(2x) + 3x(-2) [By distributive property]

2). x²(_ + 5x - 3) = (3)x² + x²(5x) + x²(-3)

3). _(x² - 3x + _) = x(x²) - (x)(-3x) + (x)(2)

4). (2x + 9)(x + 2) = 2x(x + 2) + 9(x + 2)

                            = 2x² + 4x + 9x + 18

                            = 2x² + 13x + 18

5). (z - 4)(2z + 1) = z(2z + 1) + (-4)(2z + 1)

                         = 2z² + z - 8z - 4

                         = 2z² - 7z - 4

B) 22

Step-by-step explanation:

AC = BD

6x+10 = 10x+2

simplify:

subtract 6x and 2 from both sides:

4x = 8

x = 2

AC = 6(2)+10 = 22

A car requires 45 liters of petrol to travel a distance of 330 km.

1) the distance that the car can travel on 85 liters of petrol

2) the amount of petrol that the car owner has to pay to travel a distance of 990km if a liter of petrol costs $ 2.25.

Answers

Answer:

1) The car can travel 623.3 km with 85 liters of petrol.

2) The car owner has to pay $303.8.

Step-by-step explanation:

1) The distance traveled with 85 L of petrol can be found as follows:

[tex] d = \frac{330 km}{45 L}*85 L = 623.3 km [/tex]

Hence, the car can travel around 623 km with 85 liters of petrol.

2) If the liter of petrol costs $2.25, then the amount of petrol that the car owner has to pay to travel a distance of 990 km is:

[tex]x = \frac{\$ 2.25}{1 L}*\frac{45 L}{330 km}*990 km = \$ 303.8[/tex]

Therefore, the car owner has to pay $303.8.

Lisa is planning for a party. She receives quotes from two party planners. Choice A quotes $18 per guest, plus $100 for renting the party hall. Choice B quotes $15 per guest, plus $160 for renting the party hall. Which inequality represents the number of guests Lisa can invite, if choice A were to cost less than choice B?

Answers

Answer:

x<20

Step-by-step explanation:

Building linear functions for each situation, the inequality is:

[tex]18x + 100 < 15x + 160[/tex]

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

Choice A:

$18 per guest.$100 for renting.

Thus, the cost of inviting x guests is given by:

[tex]C_a(x) = 18x + 100[/tex]

Choice B:

$15 per guest.$160 for renting.

Thus, the cost of inviting x guests is given by:

[tex]C_b(x) = 15x + 160[/tex]

A cost less than B, thus, the inequality is:

[tex]C_a(x) < C_b(x)[/tex]

[tex]18x + 100 < 15x + 160[/tex]
