Tania has 6 tiles with pictures of plants and 3 tiles with pictures of animals. Tania keeps all the tiles on a mat with the pictures hidden and mixes them up. She then turns one tile face up and finds the picture of a plant on it. She removes this tile from the mat and turns over another tile without looking. What is the probability that the second tile that Tania turns over has a plant on it?

Answered by admin AT 03/12/2019 - 10:29 AM

Initially there were 6 tiles with pictures of plants and 3 tiles with pictures of animals.
She removes one tile with the picture of a plant, so now there are 5 tiles with pictures of plants and 3 tiles with pictures of animals. There are 5+3=8 tiles in total.

The probability that the second tile has a plant on it is the number of tiles with pictures of plants (5) divided by the total number of tiles (8).

The probability is \frac{5}{8}.

Write or draw to explain a way to find each sum: 6+7, 8+4, 2+9

Step-by-step explanation:

For 6+7, on a number line we have placed a point A on value 6. On moving 7 units in the rightwards direction a point B is marked. That means when we move from 0 to point B, we get the result for 6+7 = 13.

For 8+4, on a number line we have placed a point C on value 8. On moving 4 units in the rightwards direction a point D is marked. That means when we move from 0 to point D, we get the result for 8+4 = 12.

For 2+9, on a number line we have placed a point E on value 2. On moving 9 units in the rightwards direction a point F is marked. That means when we move from 0 to point F, we get the result for 2+9 = 11.

Sam needs 5/6 cup mashed bananas and 3/4 Cup mashed strawberries for a recipe. He wants to find whether he needs more bananas or more strawberries . How can he write 5/6 and 3/4 as a pair of fractions with a common denominator

Answer: He needs more strawberries than banana.

Step-by-step explanation:

Since we have given that

Number of cups of mashed bananas is given by

\frac{5}{6}

Number of cups of mashed strawberries is given by

\frac{3}{4}

We need to find whether he needs more bananas or more strawberries.

For this we need a common denominator.

1) Taking L.C.M.  of denominator :

L.C.M. OF 6  and 4 = 12

2) Make the common denominator i.e. 12 for both the fractions.

\frac{5}{6}\times \frac{2}{2}=\frac{5\times 2}{6\times 2}=\frac{10}{12}\\\\and\\\\\frac{3}{4}\times \frac{3}{3}=\frac{3\times 3}{4\times 3}=\frac{9}{12}

so, we can see that

\frac{10}{12}>\frac{9}{12}

He needs more strawberries than banana.

Brian has a bag that contains 14 red marbles and 12 yellow marbles. He selects a marble at random, and then, without replacing the first one, selects another marble at random. What is the probability that Brian selects a red marble and then a yellow marble? Round your answer to the nearest percent.

Answer=25%

14 red marbles
12 yellow marbles
26 total marbles

To solve this, we need to first find out the probability of the individual events...

The odds of selecting a red marble is 14 out of 26 total marbles: 14/26

The odds of selecting a yellow marble after the first marble was NOT replaced is 12 out of 25. (25 since the first marble wasn't replaced: 26-1=25) 12/25

Now lets multiple both probabilities together to solve for the chance of both happening consecutively....

14/26*12/25= 168/650=84/325

84/325=0.25846153846= 25%

QUESTION POSTED AT 14/12/2019 - 05:48 PM

The product of two numbers is 713. The first number is 9 more than the second number. Which equation can be used to find x, the greater number? x(x − 9) = 713 x(x + 9) = 713 x2 − 9 = 713 x2 + 9 = 713

Let x = first number and y = second number.
The first statement is expressed as
x*y = 713
The second statement is expressed as
x = y + 9
To find x, use the second equation in terms of y, that is y = x - 9. Then substituting it to the first equation yields
x*(x - 9) = 713

How do you turn an equation into slope intercept form? how do you then graph that equation?

Slope Intercept Form Equation: mx + b = y

Use the slope, like 3/2 or 4, but first plot the y-intercept, like 3, and then put the equation to these: y = 3/2x + 4 or y = 4x + 4. Plot the y-intercept on the y- axis (the vertical line). If you were to use my examples, you would plot the y-intercept by (0,4). Then if you used my first example equation, move 2 to the right of the plotted coordinates and then up by 3. If you were to use my second equation, however, then you would move to the left of the same plotted coordinates, (0,4), 1 to the right and then up 4.

Roger Makes 70 Gallons Of Pink Paint By Mixing 21 Gallons Of Red Paint With 49 Gallons Of White Paint. What Part Of Every Gallon Is From Red Paint

This is a problem sum that has to be carefully read and understood before trying to solve it. Based on all the information's provided, the answer to the question can be easily deduced.
Quantity of pink paint made = 70 gallons
Quantity of red paint required to make pink paint = 21 gallons
Quantity of white paint required to make the pink paint = 49 gallons
Then
Quantity of red paint required to make 70 gallons of pink paint = 21 gallons
Quantity of red paint required to make 1 gallon of pink paint = (21/70) gallons
                                                                                               = 3/10 gallons
                                                                                               = 0.3 gallons
So a total of 0.3 gallons of red paint is present in every gallon of pink paint.

Bob newds to mix 2 cups of orange juice concentrate with 3.5 cups of water to make orange juice.Bobvhas 6 cups of concentrate.How much orange juice can he make?

So, Bob needs 2 cups of concentrate (I'll use the variable c to shorten it) for every 3.5 cups of water (w). When he has 6 cups of c, he has three times the original recipe, and therefore we need 3w as well. 

3.5x2=6+1=7. So we need 7 cups of water.

Now, 6 cups of concentrate + 7 cups of water = 13 cups of orange juice.

Bob can make 13 cups of orange juice.

Each veterinarian has seen 40 animals today. Two out of every 5 animals Vet A has seen have been dogs. Three out of every 8 animals Vet B has seen have been dogs. Which vet saw more dogs today? Explain your reasoning.

Basically, the fractions are 2/5 vs. 3/8. As always, in order to compare fractions, you must first have a common denominator. The easiest way to achieve that is by multiplying the two denominators by each other. 5*8=40. You must also multiply the numerators by the same thing you multiplied the denominators by, so 3*5=15, and 2*8=16. The new fractions are 16/40 vs. 15/40. Therefore, Vet A has seen more dogs.
