If the question is 5m^2 the answer is 80. And if the question is 5m2 then it is 40

Okay if you make it 5•4•2 you get 40,
BUT if this was meant to be an exponent as in “5m*2” then it would be 80.

Two distinct number cubes, one red and one blue, are rolled together. Each number cube has sides numbered 1 through 6.

algol [13]

Answer:

7/18

Step-by-step explanation:

First we need to find what values of sum we can have.

The minimum value for a cube is 1, so the minimum value for the sum is 2.

The maximum value for a cube is 6, so the maximum value for the sum is 12.

Now, we find the multiples of 6 and the multiples of 4 between 2 and 12:

4, 6, 8, 12.

To have a sum of 4, we can have the pairs:

(1,3), (2,2), (3,1)

To have a sum of 6, we can have the pairs:

(1,5), (2,4), (3,3), (4,2), (5,1)

To have a sum of 8, we can have the pairs:

(2,6), (3,5), (4,4), (5,3), (6,2)

To have a sum of 12, we can have the pairs:

(6,6)

So we have 14 pairs among the 36 (6 possibilities of each cube, so 6*6=36) total possibilities of pairs, so the probability is P = 14/36 = 7/18

Identify the solution to the following inequality: -1/2 (x+3) > x - 3

mrs_skeptik [129]

Answer:

Step-by-step explanation:

- $\frac{1}{2}$ (x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )

- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1

- x - 3 > 2x - 6 ( subtract 2x from both sides )

- 3x - 3 > - 6 ( add 3 to both sides )

- 3x > - 3

divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity

x < 1

Patricia baked some cupcakes for sale. she put half of the cupcakes equally into 6 big boxes and the other half equally into sma

mojhsa [17]

Answer:

The answer is given below

Step-by-step explanation:

Let us assume Patricia baked x number of cakes. She put half of the cupcakes (i.e x/2) equally into 6 big boxes.

6 big boxes contained $\frac{x}{2}$ cakes, therefore 1 big box would contain $\frac{x}{2}/6=\frac{x}{12}$ cakes.

Let us assume she put the other half into 14 small boxes, therefore each small box would contain $\frac{x}{2}/14=\frac{x}{28}$ cakes.

There were 45 cupcakes in 3 big boxes and 8 small boxes altogether. That is: $3(\frac{x}{12} )+8(\frac{x}{28})=45\\ 84x+96x=15120\\180x=15120\\x=84$

Therefore Patricia baked 84 cup cakes

She sold all the small boxes and collected $189, i.e she sold 14 small box for $189. Each small box = $189/14 = $13.5
