Answer:

45 square centimeters

Step-by-step explanation:

The shaded region is $\frac{1}{6}$ of the whole circle. That means, the shaded region is 1 part of 6 parts in the circle.

Shaded region has area of 7.5 square centimeters. This is 1 part.

So, the area of 6 parts would be $7.5*6=45$ square centimeters.

6 parts IS the WHOLE circle, hence, the area of the circle is 45 square centimeters.

What time between 6pm and 6:30 pm the hour and minutes hands be exactly 125* degree apart

vladimir2022 [97]

Answer:

6:10pm

Step-by-step explanation:

At 6:00 the hands are 180° apart.

The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.

The minute hand moves 1/60 of the circle per minute = 6° per minute

Angle between the hands decreases by 6-0.5 = 5.5° per minute.

180 - 5.5t = 125

t = 125/5.5 = 10 minutes

The hands are 125° apart at t minutes after 6:00, or 6:10.

Alexeev081 [22]

Answer:

cube root is what number can go into it 3 times

Step-by-step explanation:

for example, the cube root of 27 is 3, because you can times 3x3x3 and get 27. Another example is the cube root of 125 is 5, because you can times 5x5x5 and get 125.

What is the probability of drawing a diamond from a standard deck of cards on a second draw, given that a diamond was drawn on t

Charra [1.4K]

This problem is all about probability. It is the study of predicting the likelihood or chances of a certain event to happen out of all the possibilities. It is always expressed as a part of a whole. Therefore, the answer is either in fraction or in percentage.

A standard deck of card consists of 52 cards all in all. There are 13 diamond cards within the deck. So, the probability of getting a diamond card is 1/52. But we are given with a conditional probability. The first draw is sure to pick a diamond. So, the probability for this is 1 or 100%. But we should multiply this to the second scenario which is the 2nd draw. If you picked a card already, that means the total number of cards is 52 less 1. Also, because you already picked a diamond in the first draw, the diamond cards left in the deck is 13 less 1. Therefore, the probability of getting a diamond card in the second draw is

Probability = 1 × 12/51
Probability = 12/51

If it takes Ohenhen 10km to pass to Emma and it takes Emma 8km to pass to Omusi and considering Ohenhen & Omusi are at perpe

mash [69]

Answer:

12.81 km

Step-by-step explanation:

Pythagoras formula for right-angled triangles.

this scenario just says that Emma is the corner point of that triangle with an angle of 90 degrees.

the distance between Ohenhen and Omusi is the baseline (Hypotenuse c) of that triangle. and the distances to Emma are the sides a and b.

so the formula is

c² = a² + b² = 10² + 8² = 100 + 64 = 164

$c = \sqrt{164}$

c ≈ 12.81 km (rounded to the nearest hundredth).
