Answer:

1 1/3 feet long

Step-by-step explanation:

Answer:

Each of the seven smaller boards will be 1.3 feet long

Step-by-step explanation:

We must divide 9 1/3 by 7

9 1/3 / 7 =  1.333286

We now have to round to the nearest tenth which would give us:

1.3

So our final answer would be 1.3

Answer:

x = 13

Step-by-step explanation:

All triangles equal 180 degrees

Since this is an equilateral triangle, all angles have the same measurement

180 degrees divided by 3 angles = 60 degrees per angle

Make an equation based on the info given:

60 = 5x - 5

Solve:

*add 5 to both sides*

65 = 5x

*divide both sides by 5*

13 = x

Answer: (C) 42 cm

Work Shown:

(length on paper)/(real length) = (length on paper)/(real length)

(1 cm)/(7 cm) = (6 cm)/(x cm)

1/7 = 6/x

1*x = 7*6

x = 42

The actual length of the dog is 42 cm.

Answer:

Step-by-step explanation:

Answer:

y = dependent variable

k = constant of proportionality or constant rate of change

x = independent variable

Step-by-step explanation:

The equation, [tex] y = mx [/tex] represents a direct variation showing a proportional relationship between variable y and variable x.

y represents the dependent variable

k represents the constant of proportionality or constant rate of change

x represents the independent variable

Answer:

self realization, confidence

Step-by-step explanation:

also these concepts are used in real life jobs but most people think otherwise because you dont use them in a grocery store... yeah people think that, but also its so these concepts that were figured out thousands of years ago dont fade away with the newer generations

Answer:

The answer is D

Step-by-step explanation:

This problem may look complex but it isn't; the variables in the "x" column represent what would be substituted for x, and y would be what the equation would equal AFTER substituting the x variable into the equation

So for example, using d's table, I would substitute -4 for x: y = -3(-4) + 2, the answer would be 14, which is in the y column. I will do the same thing using the next variable in the x column, y = -3(-2) + 2, that would equal 8, which is also in the y column, this would not serve true in any other tables.

Answer:

I would choose B. Sorry if incorrect. Hope it helps. :)

Step-by-step explanation:

Usually the correct answer is B when I do assignments.

Answer:

B!!

Answer: 24.8 and 155.2

Step-by-step explanation:

x+x+130.4=180

2x=49.6

x=24.8

Answer:

155.2

Step-by-step explanation:

let x be the supplimentary angle

then the angle is

130.4+x

we have

130.4+x+x=180

2x=49.6

multiply both sides with 2

x=24.8

then the angle is

130.4+24.8

155.2

Answer: the answer is B

Step-by-step explanation:

You add the A,B,C numbers together for the soda for example,

Cola: 70(A) + 30(B) + 100(C) = 200

Now you just continue that for the other sodas hope this helps :)

Step-by-step explanation:

x - 8 > -3

x > -3 + 8 (add 8 to both sides)

x > 5

Hence 3.{x|x€R,x>5} is correct.

Answer:

Y =1 is a good answer for this question.

Answer:

0.25

Step-by-step explanaition:

The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.

Answer:

0.25

Answer:

[tex]m=\frac{225-135}{5-3} =\frac{90}{2}[/tex]

Step-by-step explanation:

OK i am glad to help.

Slope is [tex]\frac{y2-x2}{y1-x1}[/tex]

So, in the boxes, it is

[tex]\frac{225-x2}{y1-3}[/tex]

Our points are

5,225 and

3,135 so the slope should be

[tex]\frac{225-135}{5-3}[/tex]

This is the answer for the first box.

Second is

[tex]\frac{90}{2}[/tex].

Hope this helps plz hit the crown :D
