53. A=6.

54.we use the Pythagorean theorem =>

8^2=(8:2)^2+x^2

64=16+x^2
x^2=64-16=48

=> A=sqrt(48)= 4*sqrt(3).

A lookout tower above a canyon is 4 meters above ground level. The depth of the canyon is 16 meters below ground level. If 0 represents ground level, which number sentence correctly compares their distances above and below ground level?

A) 4<-16

B)4>-16

C)-4<16

D)-4>16

Answers

Answer:

B

Step-by-step explanation:

4 meters above. So 4 will not be negative, this eliminates C and D.

16 is definitely negative. So that eliminates C and D again.

< the number on the left of this is smaller than the right

> the number of the right of this is bigger than the left

4 is larger than -16

4>-16

B

I think it’s A because 4 is above which mean it’s positive and 16 below when negative. That means it’s greater than because the larger number eats the smallest number.

15x+3y=27 into slope-intercept form, simplifying all fractions.

Answers

Answer:

y = -5x + 9

Step-by-step explanation:

Slope-intercept form is the form

y = mx + b

So you need to rearrange the terms to get the y all by itself on the left. On the right, the x term goes first and last the constant (a plain number) see image.

PLEASE HELP!!! If the height of the lighthouse is 53 meters and the angle of elevation is 47°, which of the following may be used to find the distance, z, between the boat and the base of the lighthouse?

Answers

Answer:

tan(47)=53/z

Step-by-step explanation:

Using trig ratio tan(x)=O/A

there x is the angle of elevation, O is the side opposite the angle (the lighthouse) and A is the side adjacent the angle (distance between boat and bottom of lighthouse)

Therefore, tan(47)=53/z

H=53theta=47°

[tex]\\ \tt\hookrightarrow tan47=\dfrac{H}{B}[/tex]

[tex]\\ \tt\hookrightarrow tan47=\dfrac{53}{B}[/tex]

What is the ratio in decimal form of 75 people in a 10ft X 10ft square?

Answers

Answer:

(100 ft^2) / (75 people) is a ratio:  1.3333... ft^2/person

Step-by-step explanation:

There are 75 people in a 100 square foot area.  The amount of space (floor space) is (100 ft^2) / (75 people) = 1 1/3 square feet.

(100 ft^2) / (75 people) is a ratio:  1.3333... ft^2/person

2) Riddington and Greenwick are two small villages.
The population of Riddington has increased from 80 people to 120 people.
The population of Greenwick has decreased from 200 people to 120 people.
Show that Riddington has had the greater percentage change in its population.
You must show all your working.

Answers

Answer:

See below

Step-by-step explanation:

Find the amount of change in both cases and convert the change into percentage, then compare final results.

1. Riddington

Change:

120 - 80 = 40

Percent change:

40/80*100% = 50% increase

2. Greenwick

Change:

200 - 120 = 80

Percent change:

80/200*100% = 40% decrease

As we see 50% > 40% so this proves the statement.

Answers

Answer:

s = 71

j = 23

71 = 3j+2

71 - 2 = 3j

39 = 3j

j = 23

Answer:

j=23

s=71

Step-by-step explanation:

Here we have two parallel lines lines( UB and DK).

And we have another line, called a transversal that intersects( crosses) both parallel line. Doing so creates the following angles,

Vertical Angles, Angles are equal in measure Alternate Exterior Angles, Angles are equalAlternate Interior Angles. Angles are equalConsective Angles. Angles are equalLinear Pair Angles. Angles add up to 180

So now we look at the graph

First, we know that 3j+2 and s are vertical angles since they are across of each other. So they are equal to each other so let look at another angle first.

3j+s and 71 are Alternate Interior Angles since they lie inside the transversal and are across from each other.

Since they are Alternate Interior Angles, they are equal.

So we set them equal to each other.

[tex]3j + 2 = 71[/tex]

Subtract 2 from both sides

[tex]3j = 69[/tex]

Divide both sides by 3

[tex]j = 23[/tex]

The value of j is 23.

Know to find S, we know s is equal to 3j+2, which when we plug in 23 for j, we get 71.

So s=71

Step-by-step explanation:

Can someone please help me with all of these. And thank you.

Answers

Answer/Step-by-step explanation:

1. x = -3.6

Add 1 on both sides.

18x = 23x + 18

Subtract 23x on both sides.

Combine like terms.

Divide the answer.

-5x = 18

x = -3.6

2. x = 11/3 (2.66666...)

Add 5 on both sides.

6x = 3x + 11

Subtract 3x on both sides.

Combine like terms.

Divide the answer.

3x = 11

x = 11/3

3. x = 23

Subtract 12 on both sides.

5x = 6x - 23

Subtract 6x on both sides.

Combine like terms.

Divide the answer.

-x = -23

x=23

(that's all.)
