Answer:
C. 205.3 units²
Step-by-step explanation:
The volume of the figure is the sum of the volumes of ...
1/2 sphere of radius 2
cylinder of radius 2 and length 12
cone of radius 2 and length 9
The formulas for the volumes of a sphere, cylinder, and cone are ...
V = 4/3πr³ . . . sphere
V = πr²h . . . . cylinder
V = 1/3πr²h . . . cone
Then the sum of the volumes is ...
1/2 sphere + cylinder + cone = (1/2)4/3πr³ +πr²h +1/3πr²h'
where h is the cylinder height and h' is the cone height
= πr²(2/3r + h + 1/3h')
= π(2²)(2/3·2 +12 +1/3·9) = π(4)(16 1/3) = π(65 1/3) ≈ 205.2507
The volume of the figure is about 205.3 units³.

The sum of two numbers is 75. The second number is 3
less than twice the first. Find the numbers. Please give me the answer step by step on how to solve it.
Answers
x + (2x-3) = 75
now add both together
3x-3 =75
move over the constant
3x=78
and divide by 3
x= 26
Hope this helps!!
Answer:
x= 26 y = 49
Step-by-step explanation:
let the first number be x and second be y
then
according to the question,
x + y= 75
x + (2x- 3) = 75
x + 2x - 3 = 75
3x = 75 +3
3x = 78
x = 78/3
x = 26
thus first number is 26
and second number is 2x-3=2×26-3
= 52 - 3= 49

Taxi A charges $0.25 per mile and an initial fee of $5. Taxi B charges $0.5 per mile and an initial fee of $2. In how many miles will the cost of Taxi B will be the same than Taxi A.
Answers
Answer:
12 miles
Step-by-step explanation:
Let
x = number of miles
Taxi A:
5 + 0.25x
Taxi B:
2 + 0.5x
In how many miles will the cost of Taxi B will be the same than Taxi A
Equate cost of taxi A and taxi B
5 + 0.25x = 2 + 0.5x
Collect like terms
5 - 2 = 0.5x - 0.25x
3 = 0.25x
Divide both sides by 0.25
3 / 0.25 = 0.25x / 0.25
x = 3/0.25
x = 12 miles
x = number of miles = 12 miles

Doug is going to ride his bicycle 3,000 miles across the United States, from coast to coast. He wants to choose the route that will give him the greatest chance of success. Here's what he finds in his research:
Answers
Answer: hello your question has some missing data below is the missing data
There have been 2 attempts on the northern route from Maine to Washington. Both of those riders made it 2,000 miles and quit in Montana. There have been 19 attempts on the central route from Virginia to California; 9 of those riders didn't make it out of Virginia and the other 10 made it all the way to the Pacific. There have been 32 attempts on the southern route from Florida to San Diego. One of those riders made it the whole way. Another realized he was out of shape, and quit before he even started. The other 30 riders quit somewhere in Texas. They were evenly distributed between 1 , 300 and 1 , 700 miles. For the northern route, the median distance covered will be the mean. For the central route, the median distance covered will be the mean. For the southern route, the median distance covered will likely be the mean
answer : Doug should choose the Central route
Step-by-step explanation:
Number of Available routes = 3
Northern route ; Total distance covered = 2000 miles
Central route : Total distance between Virginia and California = 2818.5 miles
percentage of success = 10 / 19 * 100 = 52.63 %
Mean distance covered = 2818.5 * 52.63% = 1483.38 miles
southern route
Distance to be covered = 2,548 miles
number of attempts = 32
percentage of success = 1 = ( 1 / 32) * 100 = 3.12%
median distance covered by 30 riders = 1300 + ( 400 / 30 ) = 1313.33
Conclusion :
Doug should choose central route because it has the highest percentage of success and longest distance covered ( i.e. closest to 3000 miles ) and it is also coast to coast

2. B, 18 = 11 + 7
If you plug in the 7 in the y it would make sense
18 = 11 + y
Let's plug in the 7
18 = 11 + 7
and 11 + 7 = 18, so it makes sense! Therefore B is your answer for question number 2.
Answer:
B. 18 = 11 + y
Step-by-step explanation:
since y = 7
substitute it into the equation which becomes
18 = 11 + 7
which makes this statement true.
11 + 7 = 18

To solve for w, divide both sides by 4:

We can use the Pythagorean theorem to determine the length
a^2+b^2=c^2
5^2 +12^2 = c^2
25+144= c^2
169 = c^2
Taking the square root of each side
sqrt(169) = sqrt(c^2)

Answer: Choice A) Solar energy; renewable
The image shows panels that convert solar energy to electricity. This is an example of using renewable sources.
This is in contrast to something like coal energy which is nonrenewable. Coal is finite and will run out some day, unlike the sun's energy which won't run out any time soon. Sure it will eventually die off in about 5 billion years or so, but that timescale is much longer compared to the amount of coal is left. So this is a benefit to using renewable resources.
