Answer: megan went a total distance of 1 5/12 miles or 17/12 (use which ever you need)

Step-by-step explanation:

Here, we want to calculate the total distance worked around the track

We are told that she ran 9/12 and skipped 8/12

The total distance around the track will be the sum of these two

Mathematically, that will be;

9/12 + 8/12= 17/12 but if wanted in mixed fraction \(1\frac{5}{12}\)

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

Step-by-step explanation:

First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.

Multiply 2.5 on each side of the equation like this:

(12.75 x 2.5) (24.50 x 2.5) =188.75

Once you're finished, you should get 61.25 and 31.875x =188.75

Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:

61.25 - 61.25 = 0

188.75 - 61.25 = 127.5

So now your equation should look like this:

31.875x = 127.5

You have to divide 31.875 by each side now.

Once you divide them, your final answer should be 4.

so x = 4.

Answer:

this probability is 3/4.

Step-by-step explanation:

The spinner has the numbers 2, 3, 4, and 5. Since the question asks for the probability of spinning a number less than 5, we need to consider the numbers 2, 3, and 4.

Out of the four numbers on the spinner, three of them (2, 3, and 4) are less than 5.

Therefore, the probability of spinning a number less than 5 is 3 out of 4.

Answer:

You spin the spinner once.

Answer:

50.23 and 50.24 are both rational numbers.

Step-by-step explanation:

Rational numbers can be written like a ratio.

●Whole numbers (2, 15, 77) are rational bc just put a 1 underneath it (2/1, 15/1, 77/1) now its a ratio.

●Fractions are rational bc the fraction is exactly the ratio (1/2, 5/8, 65/111)

●Decimals that "terminate" that is end or stop are rational like your problem (50.23, 50.24) and ALSO decimals that repeat (2.33333..., 7.666666...) We can do some math on these and find the ratio that is equal to the decimal.

50.23

= 50 + 23/100

= 50•(100/100) + 23/100

= 5000/100 + 23/100

= 5023/100

50.23 is equal to 5023/100.

50.24 = 5024/100 = 2512/50 = 1256/25

Briefly, decimals that do not end either with no pattern or even with a pattern, but not repeating...they are Irrational. (pi, e, and any weird 4.531874569131187732678...no pattern, and 3.1121231234pattern but not a repeat)

Square roots of not-a-perfect square are Irrational (sqrt3, sqrt7, sqrt24) probably tmi, but hope this helps!

Answer:

24.7

Step-by-step explanation:

Calculation of the area of the shaded sector is 24.7:

Since

Line PQ = 5.413590865cm

BQ = 9cm

Now

cos(x) = 0.8190928022

x = 35.00591739˚

Now finally the

Area of sector = 24.7cm^2

So point B is at the centre of the circle, making the area of the shaded sector to be 24.7 .

It's about C. 333cm using the equation \(V=\frac{4}{3}\pi r^3\)

Answer:

\(c + d^2 = 96\)

Step-by-step explanation:

Given

\(c = -4\\d = 10\)

Required

Find \(c + d^2\)

To find \(c + d^2\), we simply substitute 10 for d and -4 for c in the given expression.

The step is as follows:

\(c + d^2\)

Substitute \(c = -4\\d = 10\)

\(c + d^2 = -4 + 10^2\)

\(c + d^2 = -4 + 10*10\)

\(c + d^2 = -4 + 100\)

\(c + d^2 = 96\)

The expression cannot be solved any further; so, we can conclude that when d = 10 and c = -4, \(c + d^2 = 96\)

Answer:

The answer for

x=3/4

y=3/2

Step-by-step explanation:

let bigger number be x

let the smaller number be y

x+y=3¾

x+y=15/4

x=15/4-y

x+1/2=2/3y

x+1/2=2y/3

15/4-y=2y/3

C.LT.

-y-2y/3= -15/4

-3y-2y/3= -15/4

-5y/3= -15/4

-5y×4=3×-15

-20y= -45

divide both sides by-20

-20y/-20= -45/-20

y=9/4

x+y=15/4

x=15/4-y

x=15/4-9/4

x=6/4

x=3/2

Answer:

5x + 15y =20  = - 3x +25y =75

= 8 minutes

Step-by-step explanation:

5x + 15y =20    multiply all by 3 to get 15x

15x +45y=60

- 3x +25y =75 multiply all by -5 to get 15x

15x -125y = -375

rewrite ans together

15x +45y=60

15x -125y = -375

      -80y = -315

y = -315/ - 80

y = 3.9375  = y= 4 substitute to find x

5x + 15(4 )=20  

5x +60 = 20

5x=-40

x= -40/5

x=-8

15x +45(4)=60

15x +180 =60

15x =-120

x=-8

Answer:

d

Step-by-step explanation:

You could just do process of elimination. So for the first one if you add them all up you would get 3,452 which is not correct, for the second one would not be correct since after you do 3 times 104 you can see it is wrong, for c it is also wrong since there is a 30 not a 30,000, for d it is correct since if you write it out is is 30,452, for E it is not correct just by looking at the problem, and for F it cannot be correct since it does not be the right answer

The correct answer is thirty thousand, four hundred fifty-two.

The expanded form helps us to better understand a given number. Let us take an example of the number 875294831. It is difficult to understand this number. Here an expanded form helps us to understand each of the digits based on their place value. Let us take a simple number 324 and try to find its expanded form. 324 is written in expanded form as 300 + 20 + 4. It means there are three hundred, two tens, and 4 ones in this number.

Given number:

30452

The expanded form is

=3*10000+0*1000+4*100+5*10+2*1

So, there is no match for this.

If we write in words it can be written as thirty thousand, four hundred fifty-two.

Hence, the correct option id (D).
