help plz i need it really quick

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Probability of rolling an even number P(A):

[tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Probability of flipping tails P(B):

[tex]\frac{1}{2}[/tex]

P(A OR B) = P(A) + P(B) – P(A AND B)

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex] - ([tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]) =  [tex]\frac{3}{4}[/tex]

Answer:

Brainliest please

Step-by-step explanation:

Simplifying

3x + -1s = r

Reorder the terms:

-1s + 3x = r

Solving

-1s + 3x = r

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-1s + 3x + -3x = r + -3x

Combine like terms: 3x + -3x = 0

-1s + 0 = r + -3x

-1s = r + -3x

Divide each side by '-1'.

s = -1r + 3x

Simplifying

s = -1r + 3x

Answer: Her end score would be 200 points.

Step-by-step explanation:

Add everything together like so, 200+-400+100+-600+700+200 and that equals 200

Answer:

There would be 12 gallons left

Step-by-step explanation:

If there was 76 of the 2 quarter pitchers that would make 152 Qt and 152 Qt equals 38 gallons so 50 - 38 = 12

Answer:

First combination: One $5 bill, one $1 bill, two quarters and one dime.

Second combination: One $5 bill, one $1 bill, two quarters and two nickles.

Step-by-step explanation:

I highly suggest reading it to make sure you understand it

Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60

So we have to work with $6.60

Now lets think of the obvious/easiest.

A $5 bill is going to be our best friend in this.

We have to do

6.60-5.00=x

(Don't freak out about x, it's just our place marker!!)

The reason we do 5.00 is because that's what $5 is.

So let's solve now.

6.60-5.00=1.60

So x=1.60

But you don't have to worry about x, I'm just explaining it from before.

So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.

1.60-1.00=0.60

So now we only have to figure out how to get 60 cents from any of the coins.

A quarter is 25 cents so lets use two of those

25+25=50

60=50=10

Lets recap on everything we've used so far.

We've used one $5 bill, one $1 bill, and two quarters.

Now we're going to add a dime to the mix.

A dime is worth 10 cents.

So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.

Now our second combination is going to be really easy.

We can use almost everything the exact same, we're only going to switch up the dime part.

1 dime = 2 nickles

Nickles are worth 5 cents

So we take out the dime and replace it with two nickles.

So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.

Answer:

62 percent

Step-by-step explanation:

[tex]8.37 - 7.75 \\ = 0.62 \\ 0.62 \times 100 \\ = 62\%[/tex]

Answer:

$36.38

Step by step explanation:

First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.

This gives us $0.40.

To then find out fifteen percent of $40, you then times $0.40 by 15.

This gives us 6 dollars.

Now, to work out the discount, we take 6 from 40.

$40 - $6 = $34

Now we have to work out the tax.

Again, we have to work out what 1% of $34 is.

This gives us $0.34

Then times that by 7 to find 7%

0.34 x 7 = $2.38

Since this is tax we have to add instead of subtracting.

$34 + $2.38 = $36.38 as the final bill.

Ima try to explain this in the process of elimination:

A isn't right since he only throws the ball 3 times

C isn't right, since he could catch it, miss, then catch again and would still match the criteria stated.

D Isn't right since he threw it 3 times, not twice

that only leaved B to be correct! Hope this helps!

Answer:

b and i think 4992

Step-by-step explanation:

Answer:

$699

Step-by-step explanation:

90.87 * 5 = 454.35

454.35 = 65%

/65               /65

6.99 = 1%

*100        *100

$699 = 100%

Total Cost = $699

Answer:

y+1 = -1/3(x+3)

Step-by-step explanation:

we can use this formula to  answer this question

y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the point and m indicates the slope

y-(-1) = -1/3(x-(-3)

y+1 = -1/3x-1

y = -1/3x -2

Answer:

100

Step-by-step explanation:

1000/50 = 20

5*20 = 100

Answer:

2.40$ dollars.

We find 20% of 3.00$, which is 0.6$ we then subtract that amount by the normal cost which is 3.00$, so we have an equation that looks like this 3.00$ - 0.6$ = 2.40$ dollars.
