Answer:

$\large\boxed{-\frac{35}{40},\,-\frac{3}{8},\,81,\,81.125}$

Step-by-step explanation:

In this question, we're trying to sort out the numbers from least to greatest.

Our given numbers are:

81.25
$-\frac{35}{40}$
81
$-\frac{3}{8}$

With the numbers above, we need to sort them from least to greatest.

We know that negative numbers would be the least. In this case, we have two negative numbers.

Lets turn the negative numbers into decimals to make it easier.

$-\frac{35}{40} =-0.875\\\\-\frac{3}{8}=-0.375$

The farther the negative number is from 0, the lesser value it is. So $-\frac{35}{40}$ with be the least, followed by $-\frac{3}{8}$

81 would be our next number, then 81.25 would be our greatest number since it's the greatest out of all.

When you sort them from least to greatest, you should get $-\frac{35}{40},\,-\frac{3}{8},\,81,\,81.125$

Jacob leaves his summer cottage and drives home. After

Answer:

A linear relationship can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If this line passes through the points (a, b) and (c, d) then the slope can be written as:

a = (a - c)/(b - d)

Here y will represent the distance between Jacob and his house, and the variable x represents the time that he has ben driving.

In this case, we know that after driving for 5 hours, he is 112km from home.

Then we can write this point as (5h, 112km)

We also know that after 7 hours he is 15km from home.

Then we can write this point as (7h, 15km)

Then the slope of this function will be:

a = (15km - 112km)/(7h - 5h) = -48.5 km/h

Then the equation is:

y = -(48.5 km/h)*x + b

To find the value of b, we can replace the values of one of the points, for example in the point (7h, 15km)

This means that we need to replace x by 12h, and y by 15km, then we get:

15km = -( 48.5 km/h)*7h + b

15km + ( 48.5 km/h)*7h = b = 354.5 km

then the equation will be:

y = (-48.5 km/h)*x + 354.5 km

Now we want to answer: How long had Jacob been driving when he was 209 km from home?

Then we need to only replace y by 209km, and solve for x:

209km = (-48.5 km/h)*x + 354.5 km

209km - 354.5 km = (-48.5 km/h)*x

-145.5km = (-48.5 km/h)*x

-145.5km/( -48.5 km/h) = x = 3h

So he is 209km away from his home after driving for 3 hours.

Manuel bought 9 pounds of apples. He has eaten 1.5 pounds so far and has $15

Artyom0805 [142]

Answer:

$2 per pound

Step-by-step explanation:

Let the cost of apples be x

<u>Then we have equation:</u>

(9 - 1.5)x = 15
7.5x = 15
x = 15/7.5
x = 2

<u>Cost of apple:</u> $2 per pound

Which of the following expressions shows the number of 8 character passwords that can be formed using letters and digits if the

AURORKA [14]

The number of 8 character passwords that can be formed using letters and digits if the password must begin with a letter is 26×31⁷.

<h3>What is Combination?</h3>

The combination helps us to know the number of ways an object can be arranged without a particular manner. A combination is denoted by 'C'.

$^nC_r = \dfrac{n!}{r!(n-r)!}$

where,

n is the number of choices available,

r is the choices to be made.

As it is given that the password can only be made with letters or numbers, and we know that there are only 26 letters and there are 10 numbers, therefore, the total option available is 36.

Also, it is given that the first letter of the password can only be made with letters, therefore, there are only 26 options available for the first place in the password.

The number of 8 character passwords that can be formed using letters and digits if the password must begin with a letter,

$= ^{26}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \times ^{36}C_{1} \\\\= 26 \times 31\times 31\times 31\times 31\times 31\times 31\times 31\\\\= 26 \times 31^7$

Hence, the number of 8 character passwords that can be formed using letters and digits if the password must begin with a letter is 26×31⁷.
