Step-by-step explanation:

- ( 9 - ( m + a ))

= -( 9 - ( 4 + 3))

= - ( 9 - (7))

= -( 9 - 7)

= - 2

Answer:

-2

Step-by-step explanation:

Open the bracket first

-(9-(m+a))

-(9-m-a)

-9+m+a

So let's substitute the value for the m and a

-9+4+3

Using BODMAS

Addition comes before substration

So

-9+4+3

=-9+7

=-2

So the final answer is-2

Answer:1.333

Step-by-step explanation:use the formula (l)(w)(h/3). L=2. H=2. W=1

The storage tank requires an additional 4,640 gallons of water to be filled to the top, calculated by finding the total tank capacity using the 20% already filled and subtracting the current water volume.

The student asks about the amount of water needed to fill a storage tank to the top given that the tank is already 20% full with 1,160 gallons of water. To find out how much more water is required, we first need to establish the total capacity of the tank.

Since 1,160 gallons represent 20% of the tank's capacity, we can calculate the full capacity by dividing the amount of water currently in the tank by 0.2. After finding that number, we need to subtract 1,160 from the total capacity to find the amount of water needed to fill the tank.

Calculation:

1. Calculate the full capacity of the tank:
Total capacity = 1,160 gallons / 0.20 = 5,800 gallons.

2. Calculate the gallons of water needed to fill the tank:
Gallons needed = Total capacity - Current amount of water
Gallons needed = 5,800 gallons - 1,160 gallons = 4,640 gallons.

Therefore, 4,640 gallons of water are needed to fill the storage tank to the top.

Answer:

$76.80

Step-by-step explanation:

When a product has a certain markup, you need to multiply the markup by the price of the product, and then add that to the original price of the product. 20%=0.2, and 0.2*64=12.8. Adding this to the original price, you get 64+12.8=$76.80. Hope this helps!

Answer:

$76.8

Step-by-step explanation:

64 x .2 = 12.8

64 + 12.8 = 76.8

Answer:

B) 1/5

Step-by-step explanation:

First you would have to find the total number of days.

52 + 13 = 65

The total number of days is 65.

Reread the question. The question is, "What is the approximate probability that she will see deer in her yard tomorrow?"

She has seen deer in her yard for 13 days, so the equation to figure this out would be:

13 divided by 65 = 0.2 or 1/5

I also took the Quiz and got it correct :)

(If you found this helpful and got it correct please thank, give 5 stars, and comment your feedback if you can so others know it's correct as well.)

The probability of seeing a deer in her yard tomorrow is 1/5, the correct option is B.

Probability is the likeliness of an event to happen, it has a range from 0 to 1.

Total number of days Maria saw deer is 13 days

Total number of days Maria didn't saw the deer is 52 days

The total number of days is 65

Probability of seeing a deer = Number of days deer was seen / Total          

                                                                                           number of days

Answer: B: 35ab^2c AND 7bc^2

Step-by-step explanation:

The monomials must be multiples of 7bc such as 21b^2c and 14bc^2, because the GCF of two monomials is the highest factor that divides both these monomials. GCF in this case is 7bc.

The Greatest Common Factor (GCF) of two monomials is the highest factor that divides both of these monomials. Given that the GCF is 7bc, these two monomials must have 7bc as a factor. Thus, Valerie possibly used any two monomials that are multiples of 7bc.

For example, one answer could be 21b^2c and 14bc^2. Each of these monomials has 7bc as a factor (3b, 2c, and 2b, 2c respectively). There are other possible combinations, as long as they're multiples of 7bc.

Answer:-47

Step-by-step explanation:

Because minuse +minuse is equal to pluse so we will add both equations

The correct answer is tan Theta = 12/5.

The task is to find the value of tan Theta given that in a position where its terminal side lies in Quadrant 3 and sine is -12/13. In the third quadrant, both sine and tangent are negative, so we expect a negative ratio for tan Theta. Since sine equals opposite over hypotenuse, we have:

sin Theta = opposite/hypotenuse = -12/13

The negative sign indicates that the opposite side is in the negative direction (downward in this case).

To find tan Theta, we'll use the Pythagorean theorem to find the length of the adjacent side:

opposite^2 + adjacent^2 = hypotenuse^2
(-12)^2 + adjacent^2 = 13^2
144 + adjacent^2 = 169
adjacent^2 = 169 - 144
adjacent^2 = 25
adjacent =  [tex]\sqrt{5}[/tex]

Because we're in the third quadrant, where the x-coordinate (adjacent side in the context of the unit circle) is negative, adjacent = -5.

Now, tan Theta = opposite/adjacent = -12/-5 = 12/5.

Therefore, the correct answer is D. 12/5.

Answer:

0.7 or 70 percent

Step-by-step explanation:

Jay's probability of winning the next game, based on his past record, would be 70%. However, probability doesn't guarantee future outcomes as the future performance depends on various factors.

The question requires us to find out the probability of Jay winning the next video game he plays, given his past record. Jay has won 14 out of the last 20 games, which gives us a winning probability of 14/20 = 0.7 or 70%. Probability assumes the conditions remain the same, it doesn't guarantee that the next outcome will be a win.

However, notice that past performance doesn't necessarily indicate future results, especially in random situations such as a game. The future outcome depends on the conditions of the next game he plays and his performance in it. The past winning record of 70% can be taken as an indication of Jay's skills or chances under similar conditions, but not a certainty for future games.

Final answer:

The grouping method of factoring trinomials involves separating the first and last terms of the trinomial into respective factors, and then factoring by grouping.

Explanation:

The correct answer is A. The grouping method of factoring trinomials involves separating the first and last terms of the trinomial into respective factors, and then factoring by grouping. In this method, we find two pairs of terms with common factors and group them together. Then, we factor out the greatest common factor from each pair. Finally, we factor out a common factor from the resulting binomials. Let's consider an example:

Example:

Factor the trinomial: x^2 + 5x + 6

Step 1: Separate the first and last terms: x^2 + 5x + 6 = (x^2 + 2x) + (3x + 6)

Step 2: Factor out the greatest common factor from each pair: x(x + 2) + 3(x + 2)

Step 3: Factor out a common factor from the resulting binomials: (x + 2)(x + 3)

Therefore, the factored form of the trinomial x^2 + 5x + 6 is (x + 2)(x + 3).
