After traveling 345 miles the

Mathematics

miskamm [114]3 years ago

d = total distance of the trip. We know that 345 miles is only 3/5 of the trip. Due to the fact that we know this, we can do some simple math to find the total distance. 345/3 = 115

115 * 5 = 575

This means we are looking for the equation which gives us d = 575.

Lets solve each problem:

A) 3/5 / d = 345. This would give us d = .0017. Which is way too small to be the total distance.

B) 3/5 * d = 345. This would give us d = 575. Seems like our answer, but lets keep trying the other ones.

C) 345 * d = 3/5. d = .0017, this is not right.

D) 345 / d = 5/3. This is d = 207, which is also wrong.

So our answer should be B. \frac{3}{5} *d=345

I hope this helps! :)

The chess clubcab have at most 36 members. The are 3 times as many boys as girls in the chess club. Which inequality could be us
grin007 [14]

Answer:

The number of girls is at most 9 girls

y ≤ 9

Step-by-step explanation:

The chess clubcab have at most 36 members.

At most means : Less than or equal to 36 members and it is represented by the inequality = ≤

The are 3 times as many boys as girls in the chess club.

Boys = x

Girls = y

Hence,

x = 3y

Which inequality could be used to determine the possible number of girls, x, in the chess club?

Therefore,

x + y≤ 36

3y + y ≤ 36

4y ≤ 36

y ≤ 36/4

y ≤ 9

Girls = y

The number of girls is at most 9 girls

What are the intercepts of the line -5x-4y=10
Trava [24]
  • Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.

So starting with the y-intercept, the easiest method to find it is to convert this standard form equation to slope-intercept form. Firstly, add 5x to both sides:

-4y=5x+10

Next, divide both sides by -4 and your slope-intercept form is y=-\frac{5}{4}x-\frac{5}{2}

Looking at this slope-intercept form, <u>the y-intercept is (0, -5/2).</u>

Now to find the x-intercept, just set the y-variable to zero and solve:

-5x-4*0=10\\-5x=10\\x=-2

<u>Our x-intercept is (-2,0).</u>

13. How many distinct 4-letter groupings can be made with the letters from the word champion if letters may not be repeated?
ddd [48]

Answer:

N = 1680

Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'

Step-by-step explanation:

Given the word 'champion' which is an 8 distinct Letter word. The number of 4 letter groupings that could be formed from it can be given by the permutation since in this case order of letters are important.

The number of distinct 4 letter groupings can be given as;

N = nPr = 8!/(8-4)!, where n= 8 and r = 4

N = 8P4 = 8!/(8-4)!

N= 8!/4!

N = 1680

Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'
