This size running track is usually called a 400-meter track. However, if a person ran as close to the "inside" as possible on the track, they would run less than 400 meters in one lap. How far away (in meters) from the inside border would someone have to run to make one lap equal exactly 400 meters?

Answer: 1.2 hours

Step-by-step explanation:

Given: : Time taken by Julius to complete the job alone: [tex]T_1=2\text{ hours}[/tex]

Time taken by Marcos to complete the job alone : [tex]T_2=3\text{ hours}[/tex]

Let the time taken by both to complete the job together = T

[tex]\dfrac{1}{T}=\dfrac{1}{T_1}+\dfrac{1}{T_2}[/tex]

[tex]\Rightarrow\ \dfrac{1}{T}=\dfrac{1}{2}+\dfrac13\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{3+2}{2\times3}\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{5}{6}\\\\\Rightarrow\ T=\dfrac{6}{5}=1.2[/tex]

Hence, it will take 1.2 hours to complete the job by working together.

Step-by-step explanation:

[tex]7d + 3n = 85 \\ 7d = 85 - 3n\\d = \frac{85}{7} - \frac{3}{7}x\\\\[/tex]

The slope of the equation is -3/7 and the y-intercept is 85/7

your answer would be 1/3

all you have to do is divide 68 and 4

Answer:

100 in ^2

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 ( b1+ b2) *h  where b1 and b2 are the lengths of the bases and h is the height

A = 1/2 ( 16+9) * 8

   = 1/2 ( 25) *8

   = 100 in ^2

Answer:

Step-by-step explanation

When we put toast in the toaster he didn't do anything but heat up the toast, so the property and identity of this piece of toast hasn't changed at all. When we put jam and peanut butter on it all it did was add flavor to it still didn't change the identity. But when we cut the apple in to a lot of slices the property of the apple has changed and the weight is different and the chemical property isn't the same. ( it is totally different)

Answer:

80 students

Step-by-step explanation:

The line in the middle of the box is the 50% line ( the median, which is 50% above and 50% below)

Since it is at 48, there are 50% above 48 points

3/4 of the students  had less than 70 marks

3/4 s = 120

s = 4/3 * 120

The number of students = 160

We need 50 % of the students

50% of 160

.5 * 160 = 80

Step-by-step explanation:

Multiply coordinates by 7.

Complete question is;

Write each set in the indicated form.

If you need to use "..." to indicate a pattern, make sure to list at least four elements of the set.

As you answer below, remember that the natural numbers are just the counting numbers. This means that is not a natural number, and negative numbers are not natural numbers either.

(a) Roster form: {6,8,10,12,...}

Descriptive form:

(b) Descriptive form: The set of natural numbers greater than or equal to 3 and less than or equal to 6.

Roster form:

Answer:

A) Descriptive form: A set of even natural numbers that are greater than or equal to 6.

B) Roster form: {3, 4, 5, 6}

Step-by-step explanation:

A) We are given that the roster form is;

{6,8,10,12,...}

Now, the descriptive form is just a statement that describes the given roster form.

Now, we can see they are all even natural numbers and the least is 6 while after 12,we can see that the set continues.

Thus;

Descriptive form: A set of even natural numbers that are greater than or equal to 6.

B) We are given that the descriptive form is the set of natural numbers greater than or equal to 3 and less than or equal to 6.

This means the least number in the set is 3 while the highest number is 6.

Thus,the roster form is;

Roster form: {3, 4, 5, 6}

Answer:

5.319149 oz per dollar

Step-by-step explanation:

This is a fraction equal to

10 oz ÷ 1.88 dollars

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 1.88

10 oz ÷ 1.88

1.88 dollars ÷ 1.88

=  

5.319149 oz

1 dollar

=  

5.319149 oz

dollar

= 5.319149 oz per dollar

I looked up a unit rate calculator and this is what I got because honestly i forgot how to do this but I hope it helps.
