Hello, happy Friday, I am just here with some geometry questions.
Please only answer this if you know the answer. If you have a comment, please add it to the comment box. Only answer the question if you can explain your answer and why you think it is accurate. Thanks, good luck!
Please determine if it is true or false and than explain why it is true or false.
Answers
a) False. This can be proven by the fact that a rotation around a point (not necessarily on the circles) can map 2 circles onto each other.
b) False. Rotations, reflections, and dilations (the last one applies if the circles have different radii) can map one circle onto another.
c) True. All circles are a uniform distance (the radius) from a point (the center), so there is only one length that defines a circle, the radius. Since a:b = a:b, where a = the radius of one circle while b = radius of another circle, that means that 2 circles will always be similar (because all corresponding lengths are in the same ratio)
Hope that helped!

What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
1 minute = 60 seconds
1 hour = 60 minutes
1 km = 1000 m
1 m = 100 cm
We have,
Shed dimensions in the blueprint:
Wide = 7 inches
Length = 3 inches
The scale factor:
34 inch = 3 feet
This means,
Multiply 7/34 on both sides of (1).
7/34 x 34 inch = 7/34 x 3 feet
7 inch = 21/34 feet
7 inch = 0.62 feet _____(A)
Multiply 3/34 on both sides of (1).
3/34 x 34 inches = 3/34 x 3 feet
3 inches = 0.26 feet ______(B)
From (A) and (B) we get,
Wide = 0.62 feet
Length = 0.26 feet
The actual dimension of the shed.
Length = 0.26 feet
Wide = 0.62 feet
Thus,
The dimension of the actual shed.
Length = 0.26 feet
Wide = 0.62 feet

Ralph Chase plans to sell a piece of property for $150000. He wants the money to be paid off in two ways minus−a short-term note at 12% interest and a long-term note at 9% interest. Find the amount of each note if the total annual interest paid is $15900.
The amount of the 12% note is $___. and the amount of the 9% note is $___
Answers
Answer:
The amount of 12% note is $90,000
The amount of 9% note is $80,000
Step-by-step explanation:
Missing word "The amount of the 12% note is $ and the amount of the 9% note is $"
Selling price = $170,000
Let x be the amount of money paid short term, therefore the amount of money paid long term is (170000 - x)
Given total annual interest = $18,000
Total annual interest = Interest due to short term (x) + interest due to long term (170000 - x)
18,000 = 0.12x + 0.09*(170000 - x)
18,000 = 0.12x + 15,300 - 0.09x
18,000 = 0.03x + 15,300
0.03x = 18,000 - 15,300
0.03x = 2,700
x = 2,700/0.03
x = 90,000
So, the amount of 12% note is $90,000
So long term paid money = $170,000 - $90,000 = $80,000
So, the amount of 9% note is $80,000

Start with h(t) = -16t^2 + initial height, which here is h(t) = -16t^2 + 1296. Set this = to zero, which corresponds to the object hitting the ground (h = 0):
0 = -16t^2 + 1296. Dividing all terms by -16, we get t^2 = 81, whose positive square root is 9. It takes 9 seconds for the object to hit the ground.

Estimate the percent of vehicles whose speeds are between miles per hour and miles per hour. (Assume the data set has a bell-shaped distribution.)
Answers
About 68%
Given : The mean speed of a sample of vehicles along a stretch of highway is 66 miles per hour, with a standard deviation of 4 miles per hour.
i.e.
We assume the data set has a bell-shaped distribution (i.e. Normal distribution).
To find : The percent of vehicles whose speeds are between 62 miles per hour and 70 miles per hour.
i.e . The percent of vehicles whose speeds are between miles per hour and miles per hour.
i.e . The percent of vehicles whose speeds are between miles per hour and miles per hour.
i.e. i.e . The percent of vehicles whose speeds are within one standard deviation from the mean.
According to the Empirical rule , about 68% of the population lies within one standard deviation of the mean.
It means , about 68% of vehicles lies within one standard deviation of the mean.
i.e . About 68% of vehicles whose speeds are between miles per hour and miles per hour.
i.e . About 68% of vehicles whose speeds are between miles per hour and miles per hour.

factorise 2tv+t-10v-5
and make the k the subject
Answers
Answer:
(2v + 1)(t - 5)
Step-by-step explanation:
The first two terms of 2tv+t-10v-5 factor into t(2v + 1); the last two terms factor into -5(2v + 1). Thus, (2v + 1) is a factor of 2tv+t-10v-5:
2tv+t-10v-5 = (2v + 1)(t - 5)
The required factors of 2tv+t-10v-5 to make k are (2v + 1) and (t -5).
Given that,
To factorize 2tv+t-10v-5 and make the k the subject.
Factors can be defined by splitting the value into multipliable values.
What is simplification?The process in mathematics to operate and interpret the function or expression to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here, according to the question to make k we have to factorize the 2tv+t-10v-5. So,
k = 2tv + t - 10v - 5
k = t( 2v + 1 ) - 5( 2v + 1 )
k = ( 2v + 1 ) ( t - 5 )
Thus, the required factors of 2tv+t-10v-5 to make k are (2v + 1) and (t -5).

Katie wants to know how much she needs to deposit into a two year CD account in order to earn $100 in simple interest. The account currently has a 1.5% interest rate. Round to the nearest cent . SHOW ALL WORK FOR ANY CREDIT!!
Answers
Answer:
To obtain $ 100 in simple interest with a rate of 1.5%, Katie must deposit $ 6,666.66.
Step-by-step explanation:
Given that Katie wants to know how much she needs to deposit into a two year CD account in order to earn $ 100 in simple interest, knowing that the account currently has a 1.5% interest rate, the following calculation must be performed:
X x 0.015 = 100
X = 100 / 0.015
X = 6,666.66
6,666.66 x 1.015 = 6,766.66
Thus, to obtain $ 100 in simple interest with a rate of 1.5%, Katie must deposit $ 6,666.66.
