Answer:
remember it starts with 3.14 r3 d 3.14 = 9.14 hope this helps but always start with 3.14 then multiply with the circumfederance and diameter
Step-by-step explanation:
1.
radius = 3 m
diameter = 3 × 2 = 6 m
formula = π × d
circumference = π × 6 = 18.85 m
2.
radius = 18 ÷ 2 = 9 cm
diameter = 18 cm
formula = π × d
circumference = π × 18 = 56.55 cm

How do I find the missing side length for 30 - 60 - 90 method as a radical in simplest form?
Answer:
Step-by-step explanation:
see the image below
Step-by-step explanation:
The side that is adjacent to 60 degree and 90 degree is the shortest side.
If u know the hypoutnese you can divide it by 2 to find the shortest side. for example if the hypotenuse is 10 then the shortest side is 5
If you know the other leg you can simply just remove the entire radical and just keep the whole number to find the length of the shortest side.
The side that his the adjacent to the 30 degree and 90 degree angle is the second longest side of the triangle.
If u know the shortest side, just multiply the radical
[tex] \sqrt{3} [/tex]
to the whole number.
If you know the hypotunese, divide the hypotenuse by 2 and then multiply the radical to find the length of the second shortest side
Finally, the hypotunese is the largest side. It is the slanted side length that is adjacent to the 30 and 60 triangle.
If you know the shortest side, just multiply the side length by 2 to get the hypotenuse.
If you know the other leg, remove the radical and keep the who the number and multiply the whole number by 2.
E.x if the second longest side length is
[tex]5 \sqrt{3} [/tex]
Remove the radical so it becomes
[tex]5[/tex]
then multiply it by two to find the hypotunese.
[tex]5 \times 2 = 10[/tex]
how do you decompose a number into a prime number
Answer:
Find two numbers that multiply to equal the original number; write them as numbers that branch off the original one. ..
.If either number is prime, circle it and end that branch.
Continue branching off non-prime numbers into two factors; whenever a branch reaches a prime number, circle it and close the branch.
Which is a solution to the equation StartAbsoluteValue 10 minus 5 y EndAbsoluteValue = 20?
y = 2
y = 4
y = 6
y = 10
Answer:
x=the circumference of absolute end triangularitizeationing particle matter
Answer:
Answer is y=6 (option C).
Step-by-step explanation:
|10 - 5y| = 20
First equation is just as written for first solution:
10 - 5y = 20
Subtract 10 from both sides to eliminate the 10.
-5y = 10
divide both sides by -5 to eliminate the -5 and isolate the y.
y = -2
Distribute negative sign through equation for a second solution.
|10 - 5y| = 20
-(10 - 5y) = 20
-10 + 5y = 20
Add 10 to both sides to eliminate the 10.
5y = 30
divide both sides by 5 to eliminate the 5 and isolate the y.
y = 6
y = 6 is the only answer listed in the 4 options.
Which is a simplified form of the expression -3b + 4 – 7b – 8?
Answer:

Step-by-step explanation:
The population of a town
bendly increase by 20 %
every year. If the populatich
Of the town in 2015 was 600,000 then what would be the population in 2018
Answer:
1,036,800 in year 2018
Step-by-step explanation:
20% of 600,000 is 120,000
120,000+600,000=720,000
720,000 in year 2016
20% of 720,000 is 144,000
720,000+144,000=864,000
864,000 in year 2017
20% of 864,000 is 172,800
172,800+864,000=1,036,800
1,036,800 in 2018

What is an ordered pair?An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.
Pair in Order = (x, y)
x is the abscissa, the distance measure of a point from the primary axis x
y is the ordinate, the distance measure of a point from the secondary axis y
Given, A point on a coordinate plane A(2, 16), The x-coordinate is the number of hours and the y-coordinate is the amount earned in dollars.
From this and the given options, we conclude that the correct option is
If Amy works 2 hours, she will earn $16.

3. In 2008, the population of the United States
was about 304 million. Estimate the amount
of electricity consumed per person.
Answer:
the estimated amount of electricity consumed per person is 12,828.95 million kh
Step-by-step explanation:
The computation of the electricity consumed per person is shown below:
= Electricity consumed in United states ÷ population of the united states
= 3,900000 million of kilowatt hours ÷ 304 million
= 12,828.95 million kh
Hence, the estimated amount of electricity consumed per person is 12,828.95 million kh

4b + 7 - 5b - 19
Answer:
-b-12
Step-by-step explanation:
4b+7-5b-19
4b-5b+7-19
-b+7-19
-b-12
Answer:
-b-12
Step-by-step explanation:
The like terms is 4b and -5b since they both have b so you have to combine like terms. The coefficients are 4 and 5. Then you combine the rest of the like terms which are 7 and -19 and get 12. So once simplify you get the expression -b-12
