MARKING BRAINLIEST FOR BEST ANSWER 5% of 650= 32.5 but show the work how it equals 32.5
olga_2 [115]

Answer:

650 ÷ 10 = 65, so 10% of 650 is 65.

Therefore, to get 5%, you simply halve 65, which results in 32.5.

Given the following equation, at what point will the graph intersect? f(x) =5x+1 g(x)= -2x+15
Andru [333]

Answer: (2,11)

Step-by-step explanation:

To find the point where the functions will intersect, we want to find the place that they are equal to each other. We do this by setting the equations equal to each other.

5x+1=-2x+15                       [add both sides by 2x]

7x+1=15                               [subtract both sides by 1]

7x=14                                  [divide both sides by 7]

x=2

Now, we know that the functions intersect at x=2. To find the point, we would plug x back into both equations to ensure that the points are the same.

f(2)=5(2)+1                         [multiply]

f(2)=10+1                            [add]

f(2)=11

The point on f(x) is (2,11).

g(2)=-2(2)+15                    [multiply]

g(2)=-4+15                         [add]

g(2)=11

The point on g(x) is (2,11).

Since the point at x=2 is the same for f(x) and g(x), we know that the graph intersects at (2,11).

A special deck of cards consists of 5 red cards, 20 blue cards, and 25 green cards. Svetlana selects 1 card from the special dec
Ipatiy [6.2K]

Answer:The answer is 50

Step-by-step explanation:

The first step is to add up the numbers in order to get the outcome

5 red + 20 blue +25 green =5+20+25 =50

Step 2

Probability =no of events /no of outcome

We were asked to find the probability of red

Where red represent event

And the summation of red ,green and blue represents outcome .

So probability of red =5/50 = 1/10

Step 3

Recall in the question ,we were told that the card was selected 500 times ,so we multiply the probability of getting red by 500

1/10 *500 =50

Therefore the probability of drawing a red card from the special deck 500 times is 50 .
