Mathematics
1 answer:
defon2 years ago
4 0

Answer:

V = 8491 mm^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the radius is 13 and the height is 16

V = pi * (13)^2 *16

V = 169*16 *pi

V =2704 *pi

Let pi be approximated by 3.14

V =2704(3.14)

V =8490.56

To the nearest whole number

V = 8491 mm^3

A coin is tossed 20 times. It lands on heads 9 times. What is the P(H) according to your experiment? Write your answer as a frac
Mama L [17]

Answer:

\frac{9}{20}=0.45=45%

Step-by-step explanation:

Probability is found by first forming a fraction where the numerator represents the number of desired outcomes and the denominator represents the total number of outcomes.  In this case, the desired outcomes is the amount of times the coin lands on heads (9) and the total outcomes is the number of times the coin is tossed (20):

\frac{9}{20}

Divide numerator by denominator to get a decimal: 9÷20= 0.45

Multiply the decimal by 100 to get a percent: 0.45 x 100 = 45%

a certain triangle has a perimeter of 3067 mi. the shortest side measures 71 mi less than the middle side and the longest side m
UkoKoshka [18]

Answer:

The measure of the shortest side is 851 miles

Step-by-step explanation:

Let

x ----> the measure of the shortest side

y ---> the measure of the middle side

z ---> the measure of the longest side

we know that

The perimeter of triangle is equal to

P=x+y+z

P=3,067\ mi

so

3,067=x+y+z ----> equation A

the shortest side measures 71 mi less than the middle side

so

x=y-71 ----> equation B

the longest side measures 372 mi more the the middle side

so

z=y+372 ----> equation C

substitute equation B and equation C in equation A

3,067=(y-71)+y+(y+372)

solve for y

3,067=3y+301\\3y=2,766\\y=922

Find the value of x

x=y-71\\x=922-71\\x=851

therefore

The measure of the shortest side is 851 miles

Solve (x – 3)2 = 49. Select the values of x.
PIT_PIT [208]

Answer:

<h3>x = 27.5</h3>

Step-by-step explanation:

(x - 3)2 = 49 \\  \frac{(x - 3)2}{2}  =  \frac{49}{2}  \\ x - 3 = 24.5 \\ x - 3 + 3 = 24.5 + 3 \\ x = 27.5 \\
