Given a box of 8 color crayons (Red, Blue, Green, Orange, Yellow, Brown, Black, Purple). If I remove a single crayon randomly, a

stich3 [128]

Answer: 1/56

Step-by-step explanation:

Since the box has 8 different colors, the probability of picking any color of crayon will be 1/8.

This question relates to a probability without replacement, therefore, the probability of picking the red crayon first will be 1/8. After then, there'll be 7 crayons left and the probability of picking the green crayon next will be 1/7.

Therefore, the probability that I will remove the Red and the Green crayon from the box will be:

= 1/8 × 1/7

= 1/56

This right triangle has one leg with a length of 45 units and a hypotenuse with a length of 75 units. What is the length of the

Nesterboy [21]

The length of other leg is 60 units.

Step-by-step explanation:

Given,

Length of one leg = a = 45 units

Length of other leg = b

Length of hypotenuse = c = 75 units

Using pythagoras theorem

$a^2+b^2=c^2\\(45)^2+b^2=(75)^2\\2025+b^2=5625\\b^2=5625-2025\\b^2=3600$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{3600}\\b=60\ units$

The length of other leg is 60 units.

Tom and Jerry leave from the same place in opposite directions. Tom drives 38mph. Jerry drives 50mph. In how many hours are they

devlian [24]

Answer:

Both Tom and Jerry will apart 176 miles in 2 hours .

Step-by-step explanation:

Given as:

Tom and Jerry moves in opposite direction

The speed of Tom = 38 mph

The speed of Jerry = 50 mph

Let The distance cover by Tom = x mile

The distance cover by Tom = ( 176 - x ) miles

Time taken by both are same = T hour

$\textrm(Time) = \dfrac{\textrm(Distance)}{\textrm(Speed)}$

Or, Time taken by Tom

T = $\frac{x}{38}$ ... 1

∴ x = 38 T

And Time taken by Jerry

$\textrm(T) = \dfrac{\textrm(Distance)}{\textrm(Speed)}$

Or, T = $\frac{176 - x}{50}$

So , put the value of T from 1

$\frac{x}{38}$ = $\frac{176 - x}{50}$

Or, 50 × x = ( 176 - x ) × 38

So 50 x + 38 x = 6688

Or, 88 x = 6688

∴ x = $\frac{6688}{88}$ = 76 mile

So, From, eq 1

T = $\frac{x}{38}$

or, T = $\frac{76}{38}$ = 2 hours

Hence both Tom and Jerry will apart 176 miles in 2 hours . Answer
