Step-by-step explanation:

1.

P(odd) = 3/6 = 1/2

P(blue) = 1/5

P(odd and blue) = 1/2*1/5 = 1/10

2.

Possible outcomes are 9 as all non-zero digits. And 8 is one of them.

P(8) = 1/9

3.

Non-zero digits: 1, 2, 3, 4, 5, 6, 7, 8, 9

5 of them are odd and 4 of them are even.

One digit is discounted as can't repeat and 4 out of remaining 8 are even.

P(even) = 4/8 = 1/2

4.

Remaining marbles: 2 orange, 3 black, 4 pink. Total 9

P(pink) = 4/9

5.

Each spinner has 3 colors.

P(red or orange) = 2/3

P(both red or orange) = 2/3*2/3 = 4/9

Answer:

The answer is that the cost will be a total of $142.05. That is $125.80 for Watermelon that weighs 185 lbs and $16.25 for 5 lbs of tomatoes.

Step-by-step explanation:

Given: Watermelons are .68 / lb and tomatoes are 3.25 / lb.

Let w = watermelon weight and tomato weight.

An equation would be:

.68w + 3.25t = Total cost

For 185 lb of Watermelon and 5 lbs of tomatoes:

.68(185) + 3.25(5) =

$125.80 + $16.25 = $142.05

Answer:

x>3

Step-by-step explanation:

Answer:

Step-by-step explanation:

It's like the same thing for adding. For example if you have 3 x 4. You can add 3 four times or you can add 4 three times. Like this.

3 + 3 + 3 + 3 = 12 because you know 3 + 3 =6 and 6 + 6 equals 12.

OR

4 + 4 + 4 = 12 because you know 4 + 4 = 8 and 8 + 4 equals 12.

Answer:

Amanda has 112 stamps

proof:

Lyle has 168 stamps

Shaq has 84 stamps

Step-by-step explanation:

S = number of stamps Shaquille has

L = number Lyle has

A = number Amanda has

S = 1/2L

A = 2/3L

S + L + A = 364

substituting for S and A

1/2L + L + 2/3L = 364

reduce

2 1/6L = 364

divide both sides by 2 1/6

L = 168

S = 1/2(168) = 84

A = 2/3(168) = 112

Answer: 7,874

Step-by-step explanation: I took the quiz (K12).

Answer:

1. The sum of 4 and x is 7, and to isolate the variable, you move the 4 to the other side and the equation will change into x=7-4, giving us x = 3

2. To solve this inequality, you must isolate the variable x by moving -9 to the other side. To do this, you have to divide 27 by -9, and this causes the direction of the inequality sign to change. After you divide, the inequality changes to this: x<-3

3. since there are no negative numbers involved in this inequality, you divide 3 by 1/4 (or multiply it by 4) to isolate x. this gives us x <= -12

4. To solve this algebraic equation, you must isolate the variable 3x. To do this, you must move -9 to the other side of the equation by adding 9 to the 6. this gives us 3x=15 and x = 5

5. To put x by itself, you subtract 1 by 4, giving you x<-3

Answer:

The length of each part is 3.5 inches.

Step-by-step explanation:

The question states that the bar is 7 inches long, with the two parts being equal lengths.

What you would do to find the length of each bar is doable with simple division. Take 7, and divide it by 2. 2 goes into seven 3 times, which would leave 1. Add a decimal and a zero, bring the zero down, and you get 10. 2 goes into 10 five times, giving you the 5 in 3.5.

1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.

The area of Rectangle is length times of width.

Given that the bar is 7 inches long and divided into 2 equal parts.

We need to find the length of one of those parts.

We take the whole bar as a whole number.

The two parts of the bar are considered as parts of the bar.

The seven inches is divided equally.

The length of the bar is seven inches.

We need to divide seven by two to get the length of one part.

When seven is divided by the two we get three point five inches which is the length of the one of the part of the bar.

1/2×7=3.5 inches

The equation which gives the length of the one of the part of bar is 1/2×7=3.5 inches.

Hence, 1/2×7=3.5 inches is the equation which gives the length of the one of the part of bar.

Answer:

y = 6

Step-by-step explanation:

4y - 46 + y = 4 - 5y + 10

simplify

5y - 46 = 14 - 5y

add 5 y to each side

10y - 46 = 14

add 46 to each side

10y = 60

divide both sides by 10

y = 6

Answer:

[tex]\frac{21}{4}[/tex] or 5.25 litres

Step-by-step explanation:

Hi there,

Since 1 hour is equivalent to [tex]\frac{3}{3}[/tex] and we have the amount for [tex]\frac{2}{3}[/tex] of an hour, we can find the amount Ben drinks for [tex]\frac{1}{3}[/tex] hour and multiply by 3.

To find the amount Ben drinks in [tex]\frac{1}{3}[/tex] hour, we should divide the amount at [tex]\frac{2}{3}[/tex] hour by 2.

[tex]\frac{7}{2}[/tex] ÷ 2 = [tex]\frac{7}{4}[/tex]

Now that we know the amount at [tex]\frac{1}{3}[/tex] hour, we can multiply by 3 to determine the amount of tea he drank in one hour.

[tex]\frac{7}{4}[/tex] × 3 = [tex]\frac{21}{4}[/tex]

Therefore, Ben drank [tex]\frac{21}{4}[/tex] or 5.25 litres of tea in one hour.
