Answer:

3 * 6 = 18

Step-by-step explanation:

53 * 26 =

= (50 + 3) * (20 + 6)

= 50 * 20 + 50 * 6 + 3 * 20 + 3 * 6

= 1000 + 300 + 60 + 18

Answer: 3 * 6 = 18

OlgaM077 [116]
I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.

From the lighthouse 1000 ft above sea level the angle of depression to boat a is 29 degress.a little bit later the boat moved cl
AnnyKZ [126]

Answer: The boat moved 768.51 feet  in that time .

Step-by-step explanation:

Since we have given that

Height of the lighthouse = 1000 feet

Angle depression to boat 'a' = 29°

Angle of depression  to shore 'b' = 44°

Consider ΔABC,

\tan 44\textdegree=\frac{AB}{BC}\\\\\tan 44\textdegree=\frac{1000}{BC}\\\\BC=\frac{1000}{\tan 44\textdegree}\\\\BC=1035.53\ feet

Now, Consider, ΔABD,

\tan 29\textdegree=\frac{AB}{BD}\\\\\tan 29\textdegree=\frac{1000}{BD}\\\\BD=\frac{1000}{\tan 29\textdegree}\\\\BD=1804.04\ feet

We need to find the distance that the boat moved in that time i.e. BC

so,

DC=BD-BC\\\\CD=1804.04-1035.53\\\\CD=768.51\ feet

Hence, the boat moved 768.51 feet  in that time .

The range of three numbers is 17.the mode is 24 and the median is 24 ? What are the three numbers?
vivado [14]

The answer is 7, 24, 24.

The median is the middle number.

The mode is the number which occurs the most.

The range is the difference between the largest number and the smallest number.

Since 24 is the middle number, it is the median.

Since 24 is also the number which occurs the most often, it is also the mode.

To find range, do 24-7 which is equal to seventeen.

<em>Hope it helps</em>
