I would say that the answer is A ibecause each half a pound is the same as 8 ounces. Or you can say each pound is 16 ounces. 9 * 16 = 144.

3 days after picking apples, a family had 100 apples left. After 6 days, 76 apples were left. Assuming a linear function, write

fredd [130]

Answer:

a(t) = -8t + 124

Step-by-step explanation:

The number of apples left 3 days after picking them is given by the following equation:

$a(t) = mt + b$

3 days after picking apples, a family had 100 apples left.

This means that $a(3) = 100$

$100 = 3m + b$

$3m + b = 100$

$b = 100 - 3m$

After 6 days, 76 apples were left.

So a(6) = 76. Then

$76 = 6m + b$

Since b = 100 - 3m

$76 = 6m + 100 - 3m$

$3m = -24$

$m = \frac{-24}{3}$

$m = -8$

$b = 100 - 3m = 100 - 3*(-8) = 124$

a(t) = -8t + 124.

In the first week of January, there are 49 dogs and 28 cats in an animal shelter. Throughout the month, the ratio of dogs to cat

scoundrel [369]

Answer:

35 dogs

Step-by-step explanation:

Given

$49\ dogs: 28\ cats$

Required

Determine the number of dogs for 20 cats

Represent the required number of dogs as a ratio of number of cats

$x : 20\ cats$

So, we have:

$49\ dogs: 28\ cats$

$x : 20\ cats$

Since, the ratio is the same throughout, we have:

$x : 20\ cats$ = $49\ dogs: 28\ cats$

Convert ratio to fraction

$\frac{x}{20} = \frac{49}{28}$

$\frac{x}{20} = \frac{7}{4}$

Multiply through by 20

$x = \frac{7}{4} * 20$

$x = 7 * 5$

$x = 35$

Three players enter a room and a red or blue hat is placed on each person's head. The color of each hat is determined by a coin

Drupady [299]

Answer:

If you take into account all probabilities, and work on a strategy, rather than individual guesses, you can increase the probability.

Here are the possible outcomes:

BBB

BBR

BRB

BRR

RBB

RBR

RRB

RRR

If you use the strategy:

If a person sees a blue and a red, they pass;

If a person sees a blue and a blue, they guess red;

If a person sees a red and a red, they guess blue;

The probability comes out like this:

(B=blue, R=red, P=pass)

actual guess correct?

BBB RRR no

BBR PPR yes

BRB PRP yes

BRR BPP yes

RBB RPP yes

RBR PBP yes

RRB PPB yes

RRR BBB no

As you can see, this is a 6/8, or 75% chance of being correct.
