Answer:

Option C.

Step-by-step explanation:

Even number : A number is called even if it is divisible by 2, i.e., 2, 4, 6,...

Odd number : A number is called odd if it is not divisible by 2, i.e., 1,3,5,...

It is given that m + 1 is an an even integer.

Since alternate numbers are even, therefore m must be an odd number.

If m is odd, then m-1 is even.

2m is divisible by 2, so it is always an even number. So,

2m - 2 is even.

2m+1 is odd.

2m+2 is even.

Since 2m+1 is an odd number, therefore the correct option is C.

Suav wants to use a sheet of fiberboard 27 inches long to create a skateboard ramp with a 19 ∘ ∘ angle of elevation from the gro
Triss [41]

The height of the ramp rise from the ground at its highest end to the nearest hundredth is 8.79 inches.

The situation forms a right angle triangle.

<h3>What is a right angle triangle?</h3>

A right angle triangle has one of its angles as 90 degrees. The sides can be found using trigonometric ratios.

Therefore, the hypotenuse of the right triangle formed is the length of the fiberboard.

The height of the ramp formed is the opposite side of the right triangle.

Hence,

sin 19° = opposite / hypotenuse

sin 19° = h / 27

cross multiply

h = 27 × sin 19°

h = 27 × 0.32556815445

h = 8.79034017034

h = 8.79 inches.

Therefore, the height of the ramp rise from the ground at its highest end to the nearest hundredth is 8.79 inches.

Nonamiya [84]

Answer:

B.

Step-by-step explanation:

Total coins = 11 ( 3 + 4 + 4 = 11).

The probability of picking a nickel first = 3/11 ( 4 nickels out of 11 total).

The probability of picking a dime second = 4/10 = 2/5 ( 3 dimes out of 10 coins left).

The probability of picking the third coin as a quarter = 4/9 ( 3 quarters out of 9 coins left).

The probability of picking all three in that order = 3/11 x 2/5 x 4/9 = 8/165
