Find the volume and surface area of the composite figure. Give four answer in terms of π. HELP NEEDED NOW!!! THE RED IS THE ONE I GOT WRONG!!
Answers
Answer:
Divide the figure above into a cylinder and a dome
+) the volume of the dome is
[tex]v1 = \frac{1}{12} \pi6 {}^{3} = 18\pi[/tex]
the surface area is
[tex]s1 = \pi3 {}^{2} = 9\pi[/tex]
+) the volume of the cylinder is
[tex]v2 = \pi.3 {}^{2} .13 = 117\pi[/tex]
the surface area is
[tex]s2 = 2\pi.3.13 + 2\pi.3 {}^{2} = 96\pi[/tex]
so the volume of this figure is
[tex]v = v1 + v2 = 18\pi + 117\pi = 135\pi[/tex]
the surface area of this figure is
[tex]s = 9\pi + 96\pi = 105\pi[/tex]

Draw an angle of -45 degrees in standard position . Then find the reference angle
Answers
Answer:
45°
Step-by-step explanation:
-45° would be 360°-45°=315°
Since 315° is in Quadrant IV, then its reference angle is 360°-315°=45°
So really, -45° is just 45° clockwise which is also our reference angle.

A cyclist rides his bike at 12 miles per hour. What is this speed per minute? How many miles will the cyclist travel in 20 minutes? Do not round you answers. Help thx
Answers
Answer:
In order to find the distance traveled in one minute, you have to divide the distance he can ride his bike in an hour by the number of minutes in a hour. 6/60= .1 mile per minute. If he rides his bike for five minutes, then you would multiply the number of minutes biked by the distance traveled in a minute. .1*5=.5 mile, or [tex]\frac{1}{2}[/tex] mile.
Step-by-step explanation:
The cyclist will travel 4 miles in 20 minutes.
What is Speed?Speed is the time rate at which an object is moving along a path,
To find the speed per minute, we can use the fact that there are 60 minutes in an hour. Therefore:
12 miles per hour = 12/60 miles per minute = 0.2 miles per minute
So the cyclist's speed is 0.2 miles per minute.
To find how many miles the cyclist will travel in 20 minutes, we can use the formula:
distance = rate x time
Plugging in the given values, we get:
distance = 0.2 miles per minute x 20 minutes
distance = 4 miles
Therefore, the cyclist will travel 4 miles in 20 minutes.

Explain your answer (be careful he said 1 MONTH).
Answers
Answer:
The poster say, "Open an account of $3,500 and earn at least $10 interest in 1 month!" is correct
Step-by-step explanation:
Given, A bank manager wants to encourage new customers to open accounts with principals of at least $3,500.
He decides to make a poster advertising a simple interest rate of 4.8%.
We have to find what must the principal be if the bank manager also wants to advertise that one can earn $10 the first month
We know that, banks offer simple interest
In our problem, simple interest = $10, rate = 4.8%, time = 1 month
Let us see Can the poster correctly say, "Open an account of $3,500 and earn at least $10 interest in 1 month!"?
So now, in our problem, amount = $3500, rate = 4.8% and time = 1 month =
So, the statement is correct.
Hence, amount to be invested is $2500 and poster says correctly.

which equation represents a line parallel to y= -2x+9
Answers
The equation of the parallel line is:
y = -2x + k
such that k ≠ 9.
How to represent the parallel line?
We know that two linear equations are parallel if they have the same slope and different y-intercept.
Then, a parallel line to:
y = -2x + 9
Would be something of the form:
y = -2x + k
such that k ≠ 9.
Then, for example:
y = -2x + 3
Is parallel to the given line.

Alex paid $20,448 for a new car. He will make equal payments each month or 4 years. What will be Alex's monthly car payment
Answers
Answer:
$426
Step-by-step explanation:
According to the question,
New car cost = $20,448
Time to repay = 4 years or 48 months
So, we can calculate the monthly car payment by using following formula,
Monthly car payment = New car cost ÷ Time to repay
By putting the value, we get
Monthly car payment = $20,448 ÷ 48
= $426
Hence, Alex monthly car payment is $426.
