If Daniel has two minutes and each game lasts for 15 seconds then he has eight tries to win. ( 120 seconds divided by 15 seconds = 8) And if his odds are .1 that means he has a 10% chance each game. 10% x 8 tries = 80% chance. or .8
6 1/6 minus 4 5/6
= 5 7/6 minus 4 5/6
= 1 1/6 hours
The option C) 49 inches is the circumference of the circular mat.
<u>Step-by-step explanation:</u>
- Tricia made a circular mat from a square piece of cloth.
- The measure of the side length of the square = 14 inches.
- The length of the side is same as the diameter of the circle.
- Therefore, the diameter of the circular mat = 14 inches.
<u>To find radius :</u>
Radius = diameter / 2
⇒ 14/2
⇒ 7 inches.
<u>To find the circumference of the circular mat :</u>
Circumference = 2πr
where,
π has the default value of 3.14
r is the radius of the circular mat.
⇒ 2 × 3.14 × 7
⇒ 44 inches.
∴ The circumference of the circular mat is 44 inches.
Since, it is not given in the option. The option C) 49 inches which is close to 44 inches is the right option.
Answer:
The correct answer is option A. √3
Step-by-step explanation:
From the figure we can see that aright angled triangle.
Points to remember
If a right angled triangle with angle 30°, 60° and 90° then the sides are in the ratio, 1 : √3 : 2
<u>To find the length of side opposite to 30°</u>
Let 'x' be the side opposite to the 30°, the we can write,
x : 3 : Hypotenuse = 1 : √3 : 2
Therefore x = 3/√3 = √3
The length of side opposite to the 30° is √3
The correct answer is option A. √3
Answer:
3/10 liter
Step-by-step explanation:
Assuming your description means that 4/3 liters of punch includes 2/5 liters of water, then the fraction of punch that is water is ...
(2/5)/(4/3) = (2/5)(3/4) = 3/10
3/10 of a liter of water is used in each liter of punch.
