Answer:

5 hours

Step-by-step explanation:

120 miles = 3 hrs

1 mile = 3/120 = 1/40

200 miles = 1/40 × 200

= 5 hrs

120 miles = 3 hours
1mile = 3/120 = 1/40
200 miles = 1/40 times 200
= 5 hours

(a) We have three standard 6-sided dice, colored red, yellow, and green. In how many ways can we roll them to get a sum of 9? Th

Kisachek [45]

I believe that there are 23 different ways to get a total of 20. Then we need to find the number of ways to get each of the 23 different ways. For instance, one way is 6 6 1-1-1-1- 1-1-1-1: 101 / (21-8) = 45 (different ways to get this result) 10 different dice are rolled, giving the 101 in the numerator since the 6 is used twice, divide by 21, since the 1 is used 8 times, divide by 8! Etc., etc., etc. Final answers, add all these results together. I'm not sure about part B! I'm sorry!!!

Imagine that you stop at a nearby coffee chain and purchase a $5 coffee every morning on your way to work. You do this 5 days a

tresset_1 [31]

Answer:

$6250

Step-by-step explanation:

Hello!

First, we find out how much you spend a week.

Since you buy a $5 coffee 5 days a week we multiply the price for a coffee by 5.

5 * 5 = 25.

Next, we find out how much you spend a year.

Since you do it 50 weeks a year we multiply the amount you spend a week by 50

25 * 50 = 1250

Then, we find out how much you spend in 5 years.

We multiply the cost a year by the amount of years

1250 * 5 = 6250

The answer is $6250

Hope this helps!

Left to Right

Algebra I

Coordinates (x, y)

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

P1 (4, -5) → x₁ = 4, y₁ = -5

P2 (3, 3) → x₂ = 3, y₂ = 3

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(3-4)^2+(3--5)^2}$
[Distance] [√Radical] (Parenthesis) Simplify: $\displaystyle d = \sqrt{(3-4)^2+(3+5)^2}$
[Distance] [√Radical] (Parenthesis) Subtract/Add: $\displaystyle d = \sqrt{(-1)^2+(8)^2}$
[Distance] [√Radical] Evaluate exponents: $\displaystyle d = \sqrt{1+64}$
[Distance] [√Radical] Add: $\displaystyle d = \sqrt{65}$

Which of the following is a trinomial with a constant term?

myrzilka [38]

Answer:

D. x + 4y + 7

Step-by-step explanation:

A constant term is a term that is a number with no variables (letters) attached to it.

In this case, D is your answer, for the term 7 is a constant, with no variables next to it.
