For a research paper, a student spent 6/7 hours searching the internet on website A and 1/5 hours on website B. How much longer

solong [7]

Answer:

Step-by-step explanation:

Lets first convert the two fractions into common denominations.

$\frac{6}{7} =\frac{30}{35}$

$\frac{1}{5} =\frac{7}{35}$

Now we just have to find the difference

$\frac{30}{35}-\frac{7}{35} =\frac{23}{35}$

Matt Bonner has 8 dimes, 9 pennies, and 4 quarters in his pocket. If each coin is equally likely to be pulled out of his pocket

Lesechka [4]

Answer:

B. 0.602%

Step-by-step explanation:

Probability is essentially (# times specific event will occur) / (# times general event will occur). Here, we have a few specific events: draw a quarter, draw a second quarter, draw a penny, and draw another penny. The general event will just be the number of coins there are to choose from.

The probability that the first draw is a quarter will be 4 / (4 + 8 + 9) = 4/21.

Since we've drawn one now, there's only 21 - 1 = 20 total coins left. The probability of drawing a second quarter is: (4 - 1) / (21 - 1) = 3/20.

The probability of drawing a penny is: 9 / (20 - 1) = 9/19.

The probability of drawing a second penny is: (9 - 1) / (19 - 1) = 8/18.

Multiply these four probabilities together:

(4/21) * (3/20) * (9/19) * (8/18) = 864 / 143640 ≈ 0.602%

The answer is B.

Marni writes this system to determine how much of each ingredient Alyssa plans to buy. She uses x to represent

liubo4ka [24]

Answer:

Alyssa buys 4 cups of frozen fruit puree and 2 cups of yogurt.

Step-by-step explanation:

Here, x = Represent cups of frozen fruit puree

y = Represent cups of yogurt.

The given system of equations by Marni are:

x + y = 6,

2x + 3y = 14

After first step of elimination,the equations are:

-2x - 2y = -12

2x + 3y = 14

Now, ADD BOTH THE EQUATIONS to eliminate the variable x:

-2x - 2y + (2x + 3y) = -12 + 14

or, y = 2

Now, put y =2 in x + y =6, we get

x = 6 - y = 6 -2 = 4

So, x = 4 and y = 2 is the solution of the given system.

Hence, Alyssa buys 4 cups of frozen fruit puree and She buys 2 cups of yogurt.

Someone please help me on these 2 problems!

Veronika [31]

1) function 2) not a function

the first one is a function because its y values are the same number (3), which means it is a horizontal line and horizontal lines are functions.

the second one is not a function because the coordinates cannot have different inputs but different outputs. each input must have only one output.

the coordinates for the second one are:

(2,5); (1,1); (1,2); (3,2)

and <u>a function cannot have two same x-coordinates</u>. it must pass the vertical line test which is a way to tell if something is a function or not. since the second graph does not pass the vertical line test, it is not a function

hope this helps :)
