Solve the inequality. |2x-6|+7 less than 15

9514 1404 393

Answer:

  a) radius: 6 (m); mass: 22 (kg)

  b) volume: 19 (m³)

  c) d ≈ 2.8×10^3 kg/m³

Step-by-step explanation:

The order of magnitude is the exponent of 10 when the number is written in scientific notation.

a) radius: 1.6×10^6 m, so the order of magnitude is 6 when the units are meters.

  mass: 4.8×10^22 kg, so the order of magnitude is 22 when the units are kg.

__

b) The volume is ...

  V = (4/3)πr^3 ≈ 1.716×10^19 m^3, so the order of magnitude of the volume is 19 when the units are m^3.

__

c) The ratio of mass to volume is ...

  d = (4.8×10^22)/(1.716×10^19) ≈ 2.8×10^(22-19) = 2.8×10^3 kg/m^3, so the order of magnitude is 3 when the units are kg/m^3.

Answer:

4 gallons/1 day

Step-by-step explanation:

What is a rate? A rate is writing a ratio in fraction form. A ratio is the proportion of two things. (ex: for every 1 dog, there are two cats.)

Creating the ratio: For the ratio, there is no given amount of which one needs  to come first, but because it is about the milk, I put that first. In the problem it says 12 gallons for 3 days so: 12/3

Simplifying: To simplify, think of the largest factor between the two numbers. If you can't immediately, think of one factor in common and keep simplifying. In this case, 4 is the greatest common factor between these. To simplify, divide both sides by four, and that is your answer: 4: 1

Answer:

12 remainder 3

Step-by-step explanation:

94- 7=87

87-7=80

80-7=73

73-7=66

66-7=59

59-7=52

52-7=45

45-7=38

38-7=31

31-7=24

24-7=17

17-7=10

10-7=3

We were able to subtract 7 from 94 12 while times! We ended up with a remainder of 3, our answer can be written as 12 R 3 or if you wnat it in decimal form its or 13.43

Answer:

Cos 2theta = -3/5

Step-by-step explanation:

Given that;

tan theta = -2

tan theta = -2/1 = opp/adj

hyp^2 = (-2)^2+1^2

hyp = √4+1

hyp = √5

sin theta = opp/hyp

sin theta = -2/√5

Cos theta = adj/hyp

Cos theta = -2/√5

Cos 2theta = 1-2sin^2 theta

Cos 2theta = 1- 2(-2/√5)^2

Cos 2theta = 1- 2(4/5)

Cos 2theta = 1- 8/5

Cos 2theta = (5-8)/5

Cos 2theta = -3/5

The point estimate of the proportion of women who trust recommendations made on Pinterest is of 0.78.

Step-by-step explanation:

To find the point estimate of the proportion of women who trust recommendations made on Pinterest, we find the sample proportion.

In this question:

150 women

117 trust recommendations made on Pinterest.

Point estimate:

[tex]p = \frac{117}{150} = 0.78[/tex]

The point estimate of the proportion of women who trust recommendations made on Pinterest is of 0.78.

Answer:

The null hypothesis is [tex]H_{0}: \mu = 8[/tex], and the alternative hypothesis is [tex]H_{a}: \mu < 8[/tex]

Step-by-step explanation:

At the null hypothesis, we test if the mean is equal to a certain value.

At the alternate hypothesis, we test if the mean is less than, more than, or different of the value tested at the null hypothesis.

Claims to lose an average of 8 pounds the first month

This means that the null hypothesis is [tex]H_{0}: \mu = 8[/tex]

If the FTC finds evidence that the average is less than 8 pounds, the agency will file a lawsuit against the company for false advertising.

FTC tests if the mean is less than 8, so the alternate hypothesis is [tex]H_{a}: \mu < 8[/tex]

Answer:

[tex]6\sqrt2\\OR\\8.48528137[/tex]

Step-by-step explanation:

The area of a sector of a circle is found by:

[tex]A = \frac{\theta*r^2}{2}[/tex]

The question asks for the radius so the equation above can be repurposed

[tex]r = \sqrt\frac{2A}{\theta}[/tex]

A = 3pi

angle = pi/12

[tex]\frac{6\pi}{\pi/12} = \frac{72\pi}{\pi} = 72[/tex]

[tex]\sqrt{72} = 6\sqrt2 = 8.48528137[/tex]

Answer:

72

Step-by-step explanation

48 + k+l =180

48 +90+l =180

138 +l = 180

l=180 - 138

l = 42

now

l+m+n= 180

42 +m+66 =180

108+m= 180

m= 180 -108 m =72

Answer:

x² + 4x

Step-by-step explanation:

Area of the rectangle = length × width

width = x

Therefore,

Area = x(x + 4)

Area = x*x + x*4

x² + 4x

Answer:

30027.86

Step-by-step explanation:

Answer:

$97.17

Step-by-step explanation:

First, subtract 85 from 668:

668 - 85

= 583

This means that our budget for all of the days excluding the last day is $583

To find how much can be spent on the remaining days, divide 583 by 6:

583/6

= 97.17

So, approximately $97.17 can be spent on the remaining days
