Answer:

Of all 6 faces it would be 150

Step-by-step explanation:

If one side of the cube is 5cm long, then l × w = area of a face, so if it is a cube then all 4 sides are the same on a face so 5 × 5 = 25, so 25 × 6 faces = 150

150

Step-by-step explanation:

I think its 150:

~because~

1. 2WL+2WH+2LH

2. 2(5*5)+2(5*5)+2(5*5)

3. 50+50+50 or 50*3

4. 150

tatuchka [14]

Answer:

64/200 times the spinner will land on vowel

Step-by-step explanation:

On the table, the chart says 10 times for A and 6 times for E. This means that the experimental probability for rolling a vowel in a trial of 50 rolls is 16/50.

The next step is create equal ratios. 16/50 = x/200. 50 times 4 is 200 so 16 times 4 is 64.

Two groups of staff at a store are making flowers to decorate the entrance. If Group A were to do it alone, it would take them 1

Tcecarenko [31]

Answer:

$\dfrac{6750}{7}$

Step-by-step explanation:

Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make $\dfrac{x}{10}$ flowers in an hour. If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make $\dfrac{x}{15}$ flowers in an hour.

The groups decided to work together. They can make $\dfrac{x}{10}+\dfrac{x}{15}=\dfrac{x}{6}$ together in an hour and it takes them $\dfrac{x}{\frac{x}{6}}=6$ hours. Group B took a break for 1 hour and 40 minutes ( $1\dfrac{2}{3}$ hour), then Group B works

$6-1\dfrac{2}{3}=4\dfrac{1}{3}$ hours.

Thus,

$\dfrac{x}{10}\cdot 6-\dfrac{x}{15}\cdot 4\dfrac{1}{3}=300,\\ \\\dfrac{3x}{5}-\dfrac{13x}{45}=300,\\ \\14x=300\cdot 45=13500,\\ \\x=\dfrac{13500}{14}=\dfrac{6750}{7}.$
