79.(b)this is because you have six choices, 3 red, 1 blue, 1 yellow, and 1 green and since it says not red you only have 3 choices, blue yellow and green, so the fraction would be 3/6. You can simplify the fraction by dividing it by 2 and you would get 1/2.

80.the answer will still be (b) which is the same explanation for 79.

81. (C) because remember that the first time you only had a 50% (1/2) chance of getting red and the second chance of getting a red will be the same but not
Its not likely You can get a red.

The value (in cents) of the change in a purse that contains twice as many nickels as pennies, five more dimes than nickels, and

nexus9112 [7]

Value of the pursue in cents: $131p+175$

Step-by-step explanation:

Let's call:

$p$ = number of pennies

The problem tells us that the pursue contains twice as many nickels as pennies, so the number of nickels is

$n=2p$

Also, the pursue contains five more dimes than nickels, so the number of dimes is

$d=n+5=2p+5$

And finally, the pursue contains as many quarters as dimes and nickels combained, so the number of quarters is

$q=d+n=(2p+5)+2p=4p+5$

The value of each type of coin is:

Penny: 1 cent

Nickel: 5 cents

Dime: 10 cents

Quarter: 25 cents

So, the total value of the pursue in cents is:

$1p+5n+10d+25q$

And substituting,

$=p+5(2p)+10(2p+5)+25(4p+5)=\\p+10p+20p+50+100p+125=\\131p+175$

So, this is the value of the change in the pursue in cents.

Given h(x)=-3x-4h(x)=−3x−4, find h(0)

bogdanovich [222]

Answer:

h(0) = -4

Step-by-step explanation:

Put the value where the variable is and do the arithmetic.

h(x) = -3x -4

h(0) = -3·0 -4 = 0 -4

h(0) = -4

_____

<em>Additional comment</em>

In general, a polynomial function evaluated when the variable is zero will have the value of any added constant. All of the variable terms will be zero. Since the constant in this function is -4, we know immediately that h(0) = -4.

Order from least to greatest: 1/8, 0.78, 15%, 1/20

Mrrafil [7]

Answer:

1/20, 1/8, 15%, 0.78

Step-by-step explanation:

Order from least to greatest: 1/8, 0.78, 15%, 1/20

1)Convert all into decimals to make it easier, this can be done with a simple look up of a conversion calculator!

1/8 = .125

15% = .15

1/20 = .05

0.78 = 0.78 (duh)

Then simply put them in order. Hope this was clear!
