Kayla rolls two numbers cubes numbered 1 to 6. What is the probability that the sum of the numbers rolled will be 5

1 answer:

6 0

There are 2 cubes and each cube has 6 sides. There is a 1/6 chance of rolling a 5 for ONE cube (since each side is a different number ranging from 1 to 6). But, since we have to cubes, it would be 1/3. This is because your chance to roll a five is doubled due to 2 cubes.

Can a right triangle have two angles that measure 25 and 65

Art [367]

Yes, because there would only be 1 right triangle and all the angles need to add up to 180 degrees and 90+25+65=180.

Williiam lost 25% of his marble,gave 1/6 of the remainder to his.Brother and had 120 marbles left.How many marbles did he have a

bija089 [108]

Answer:

Number of marbles with Williams at the starting = 192

Step-by-step explanation:

Let total number of marbles with Williams = m

He lost marbles = 25% of the total number

= $\frac{25}{100}\times m$

= $\frac{m}{4}$

Remaining marbles with Williams = m - $\frac{m}{4}$

= $\frac{3m}{4}$

He gave marbles to his brother = $\frac{1}{6}$ th of the remaining marbles

= $\frac{1}{6}\times \frac{3m}{4}$

= $\frac{m}{8}$

Remaining marbles after giving marbles to his brother = 120

Therefore, $\frac{3m}{4}-\frac{m}{8}=120$

$\frac{6m}{8}-\frac{m}{8}=120$

$\frac{5m}{8}=120$

m = $\frac{120\times 8}{5}$

m = 192

Number of marbles with Williams at the starting = 192

Alex_Xolod [135]

after solving $7-2(x+2)$ we get $x>2$

Step-by-step explanation:

We need to find the value of x in:

$7-2(x+2)$

Solving:

$7-2(x+2)$

So, after solving $7-2(x+2)$ we get $x>2$

Irina rode her bike to work at an average speed of 16 miles per hour. It started to rain, so she got a ride home along the same

Sedaia [141]

Answer:

0.7 hours

Step-by-step explanation:

Given that Irina was able to make the same distance from work to home in 0.4 of an hour at 27 miles per hour, we can use this rate and time to find the distance she travels to and from work using the general formula:

d = rt, where d=distance, r = rate and t = time

d = 27(0.4) = 10.8 miles

Since the distance from Irina's home to work is 10.8 miles, we can again use the formula 'd = rt' to find the time it takes her to bike to work at a rate of 16 miles per hour and solving for time, 't':

10.8 = (16)t

t = 0.7 hours
