Answer:

Step-by-step explanation:

This question isn't worded the greatest, there are two ways you can read this.

1. The quotient of a number and -9, increased by 10, is 11

2. The quotient of a number, and -9 increased by 10, is 11

The first equation will look like this

$\frac{x}{-9} +10 = 11$

And the second will look like this

$\frac{x}{-9+10} = -11$

So I have solved for both (I personally believe the second way of reading the question is the correct way)

A bowl has 9 green grapes and 13 grapes. Henry randomly chooses a grape, and eats it, and then choose a another grape What is th

Sunny_sXe [5.5K]

Answer:

$\frac{72}{462}$ or $\frac{12}{77}$ (simplified)

Step-by-step explanation:

Based on the information provided within the question it can be said that in order to calculate the probability of both grapes being green we need to find the probability of each grape being green separately and then multiply those probabilities together

In the first choice, there are a total of 22 grapes (9+13), 9 of which are green. Therefore the probability of the first chosen grape being green is $\frac{9}{22}$

In the second choice,since we removed one grape there is now a total of 21 grapes (22-1), 8 of which are green. Therefore the probability of the second chosen grape being green is $\frac{8}{21}$

Now we multiply both probabilities together to calculate the probability that both grapes are green in a sequence.

$\frac{9}{22} * \frac{8}{21} = \frac{72}{462} or \frac{12}{77}$

Dixon deposited $2000.00 in an account that paid 5% interest compounded annually. How much interest will the account earn in two

anastassius [24]

Dixon will earn $2,205.00 in two years. Every year he earns 5% of the original amount each year. Multiply 2000 by 0.05 (which is 5% in decimal form). This equals to 100. Add this to 2000 to get 2100. Multiply that number by 0.05 also to get 105. Add that to 2100 and get $2205. (Hopefully this is correct, i learned this a while ago and this is what I thought of on the top if my head).

A scale model of a house is 110 the size of the actual house. One of the bedrooms in the house is 16 feet long. Which expression

kenny6666 [7]

Answer:

model measurement = actual measurement / 110

Step-by-step explanation:

(I believe you have a typo in your answer where the scale is 1:110. Hard to believe one would make a model house 110 times the size of a physical house, haha!)

A/3=7 can simeone help me out with this

Nana76 [90]

Right now you have a/3 = 7. You cannot know what a is yet because it is being divided by 3.

You just need to figure out a way of getting rid of that 3 so you just have a by itself. The way you can get rid of the 3 is by multiplying a/3 by 3, as that will just leave you with a (multiplying is the opposite of dividing so it cancels out).

However, as you’re multiplying a/3 by 3, you also have to multiply 7 by 3 (which is 21) as you have to do the multiplication on both sides of the equation.

Therefore, you’re left with a = 21
