Question:

During a walk-a-thon, Noah's time in hours was t, and distance in miles, d, are related by the equation [tex]\frac{1}{3}d = t[/tex].  A graph of the equation includes points (12,4).

1. Identify the independent variable.

2. What does the point (12,4) represent in this situation?

3. What point would represent the time it took to walk [tex]7\frac{1}{2}[/tex] miles?  

Answer:

(a) d

(b) He spent 4 hours to walk 12 miles

(c) [tex](7\frac{1}{2},2\frac{1}{2})[/tex]

Step-by-step explanation:

Given

[tex]t = \frac{1}{3}d[/tex]

Solving (a): The independent variable

The independent variable, in this problem is the distance walked. Because the distance walked stands alone, and it is when the distance is known, that the time spent is known.

Hence:

The independent variable is distance (d)

Solving (b): What (12, 4) represents

This implies that:

[tex]distance = 12[/tex]

[tex]time\ spent = 4[/tex]

So: He spent 4 hours to walk 12 miles

Solving (c): Point to represent the time to walk [tex]7\frac{1}{2}[/tex] miles

This implies that:

[tex]d = 7\frac{1}{2}[/tex]

Substitute [tex]d = 7\frac{1}{2}[/tex] in [tex]t = \frac{1}{3}d[/tex]

[tex]t = \frac{1}{3} * 7\frac{1}{2}[/tex]

Express as improper fraction

[tex]t = \frac{1}{3} * \frac{15}{2}[/tex]

[tex]t = \frac{5}{2}[/tex]

Express as mixed number

[tex]t = 2\frac{1}{2}[/tex]

So: The point is, [tex](7\frac{1}{2},2\frac{1}{2})[/tex]

Answer:

The answer is 8.304 then 8.92 then 167/20 then 8 3/10. :)

Step-by-step explanation:

Answer:

8 3/10, 8.304, 167/20, 8.92

Step-by-step explanation:

Turn all of them into decimals

8 3/10 = 8.30

8.304

167/20 = 8.350

8.92

Answer:

72 degrees is the larger angle

Step-by-step explanation:

SImple ratio problem

So we got a ratio of 4:1 that eqauls to 90 degrees when added up. We can jsut add the 2 numbers 4+1 which will be 5. Now divide 90 by 5 which will equal 18. Now we multiply 18 by each number int he same order of the ratio.

4*18: 1*18

72:18 which equals 90. SInce they ask for the larger angle the answer will be 72.

Answer:

57.475 ft2

Step-by-step explanation:

12.1x9.5= 114.95

114.95/2= 57.475

Answer:

[tex]\Huge\boxed{57.475 ft^2}[/tex]

Step-by-step explanation:

Hello there!

The following figure shown is a triangle

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base and h =height

The height of the triangle is 12.1 ft and the base length is 9.5ft

Knowing this information all we have to do is plug in the values into the formula

[tex]A=\frac{12.1*9.5}{2} \\12.1*9.5=114.95\\\frac{114.95}{2} =57.475\\A=57.475[/tex]

So we can conclude that the area of the triangle is 57.475 square feet

Answer:

Sample space: {1, 2, 3, 4, 5, 6}

Simple event

Step-by-step explanation:

Sample space is a list of all the possible outcomes.

This is a simple event because you are only doing one event, such as rolling a die.

A compound event would be multiple simple events, such as flipping a coin and choosing a marble from a bag.

Answer:

  see below for the graph

Step-by-step explanation:

We can specify the location of the minimum and the axis of symmetry using the vertex form of the quadratic equation:

  y = a(x -h)² +k . . . . . . . vertex (h, k); scale factor 'a'

We can put the given values into the equation to see what 'a' needs to be to make the function have the desired y-intercept.

  -3 = a(0 -(-2))² +(-5)

  2 = 4a . . . . add 5 and simplify

  a = 1/2 . . . . divide by 4

The equation for the desired function can be ...

  y = 1/2(x +2)² -5

Answer:  Question 1 is x=9

Question 2 is y=-3

Step-by-step explanation:

Answer:

Median is 18

Step-by-step explanation:

Firstly you have to fine y by using your mean

Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15

22+18+2y+1+10+20 over 5 =15

71+y over 5 =15

Cross multiple

71+y=75

y=4

22,18,9,10, 20

Rearrange

9,10,18,20,22

The median is 18
