What is 200.96 rounded to the nearest hundredth?

1 answer:

8 0

200.96 rounded to the nearest hundredths would be 201 because in you decimal places you have .96 and your thousandths place is 6 so you would round. Up the 9 to 10 so you would have to make 200 into 201 therefore your answer would be 201

You have a set of cards labeled 1-10. Set A is drawing an even card. Set B is drawing a 8 or higher. What is the P ( A ∪ B ) ?

creativ13 [48]

set A = {2, 4, 6, 8, 10} (only even cards)

set B = {8, 9, 10} (8 or higher)

( A ∩ B ) means the numbers which are common in both sets .

They both have 8 & 10 in common.

So the answer is: P(A ∩ B) = {8,10}

A landing pad for a helicopter is in the shape of a circle with a radius of 7 meters. Which of the following is closest to the a

ANTONII [103]

Answer:

The approximate value of the area is $153.86\ m^{2}$

Step-by-step explanation:

we know that

The area of the circle (landing pad) is equal to

$A=\pi r^{2}$

we have

$r=7\ m$

substitute

$A=\pi (7)^{2}$

$A=49\pi\ m^{2}$ ----> exact value of the area

Find the approximate value

assume $\pi=3.14$

$A=49(3.14)=153.86\ m^{2}$ ------> approximate value of the area

oksano4ka [1.4K]

Answer:

881.5 meters.

Step-by-step explanation:

The horizontal plane at the level of wai-kin's eyes divide the height of the cliff into two parts. Let the upper part be represented by x and the lower part be represented by y.

The height of the cliff = x + y

Applying the appropriate trigonometry functions.

To determine the value of x;

Tan θ = $\frac{opposite}{adjacent}$
