Hello from MrBillDoesMath!

Answer: I'd guess it's "find the next number in the sequence" (which is 54)

Discussion:

9 * 1 = 9

9 * 2 = 18

9 * 3 = 27

9 * 4 = 36

9 * 5 = 45

9 * 6 = 54

Thank you,

MrB

Answer:

m<R=48.2 to the nearest tenth

Step-by-step explanation:

1. sin(m<T)=2/3

m<T=arcsin(2/3)=41.81 degrees

m<R=180-90-m<T=180-90-41.81=48.19 degrees

Help please lol :)))))))

How come it’s a right triangle, I think you do a2+b2=C2. Therefore, you do 9.4 times 9.4 and then 15.1 times 15.1. So it will be 9.4 + b2=15.1. 88.36+ b2=228.01. Then you subtract that and it will be 139.65. Then you do square roots because you are trying to get rid of the second power. And the final answer is 11.81736011. How they told you to round it to the nearest tenth, I will be 11.8. I think this is the answer.

$22 is how mush in quarters, how do u find that out??

Serhud [2]

$22 = 88 quarters
One dollar = Four quarters
22 x 2 = 44
22 x 3 = 66
22 x 4 = 88

When we say two quantities $x$ and $y$ are proportional to one another, there are two ways we could mean this.

- If $x$ is *directly* proportional to $y$ , then we mean that as $x$ changes, $y$ changes in the same direction. In other words, if $x$ is in/decreased, then $y$ also in/decreases. The rate of in/decrease doesn't have to be one-to-one; for example, we could have $x$ increase by 1 unit while $y$ would proportionally increase by 5 units. In this case, we'd have $y=5x$ .

- On the other hand, if $x$ is *inversely* proportional to $y$ , then a change in $x$ results in a change in $y$ that goes in the opposite direction. A common example involves taking a rectangle of constant area and adjusting the width $x$ and length $y$ . If the rectangle has an area of 5 square units, then we could have $x=5$ and $y=1$ , or we could have $x=4$ and $y=\dfrac54$ , or $x=3$ and $y=\dfrac53$ , or any combination of $x$ and $y$ such that $xy=5$ is satisfied.

In both cases, we call 5 the "constant of proportionality".

On to your exercises:

(1a) Looks like $a$ stands for number of apples. Then we're told that the cost $c=2.3a$ , which means that for every apple, the cost increases by 2.3 dollars. So the constant of proportionality is 2.3. In the language of proportionality, we could then say that the cost of apples is directly proportional to the number of apples by a factor of 2.3.
