Answer:

Lol I hope she didn't hit you yet. The answer is x=14 :)

Step-by-step explanation:

So the first thing that you would want to do is find what 9 is multiplied by to get 21. To do this, we can just do a simple algebraic equation: 9x=21. The answer is 7/3 because mAgIc. So now, we can also multiply 6 by 7/3. this would be 42/3 because of more MaGiC. 42/3 divides into 14 because im just obviously a mage. lol I hope this helped.

BigorU [14]

Answer:

2 cakes with the sugar she has and there will still be some sugar left.

Step-by-step explanation:

Amount of sugar in the cabinet of Cassie = 1/2 pound

Amount of sugar required by Cassie to make her cake recipe = 2/10 pound

= 1/5 pounds

Then

The number of cakes that Cassie can make = (1/2)/(1/5)

= 5/2

= 2 1/2

1. It takes the Earth 24 h to complete a full rotation. It takes the sun approximately 25 days, 9 h, and 7 min to complete a ful

brilliants [131]

Note that there are 24 hours in 1 day, and 60 minutes in 1 hour

First, multiply 25 with 24

25 x 24 = 600

Next, add 600 with 9 hours

600 + 9 = 690

Note that there are 60 minutes in 1 hour. Divide 7 minutes with 60

7/60 = ~0.12 (rounded)

~690.12 hours is your answer

hope this helps

A die with six faces has the number 1 painted on three of its faces, the number 2 painted on 2 of its faces, and number 3 on one

salantis [7]

Answer:

a) S = {1, 2, 3}

b) P(odd number) = $\frac{2}{3}$

c) No

d) Yes

Step-by-step explanation:

a) The sample space is the set of all possible outcomes. By definition, the elements of a set should not be repeated. Hence, the sample space S = {1, 2, 3}

However, the sample is not equiprobable because each element has different probabilities.

b) P(odd number) = $\frac{number of odd digits}{number of faces}=\frac{4}{6}=\frac{2}{3}$

Note that the odd numbers are 1 (on three faces) and 3 (on one face).

c) The fact the die has been biased does not change the possible outcomes. It only changes the probability of getting any given number.

d) Because the 3-face has been loaded, this probability changes. In fact, it is calculated thus:

Let's assume the probability for 1 or 2 is $x$ . Then that of 3 is $2x$ (because it is twice the others). The sum of probabilities must be 1.

$x+x+x+x+x+2x=1$

$7x=1$

$x=\frac{1}{7}$

P(odd number) = $3\times$ Prob(1) + Prob(3)

= $3\times\frac{1}{7}+\frac{2}{7}$ = $\frac{5}{7}$

Which is the graph of y = 1/x?

irina1246 [14]

answer: the first graph

explanation:

it would not be the second one because it is a slope (y = mx + b) and so would be the third choice.

i don't think it would be the last one because it's going only up to 40. which the equation say only y = 1/x and it's not a big number equation.

hope this helps! ❤ from peachimin

i attached this image which is sorta similar to the the to this equation:
