Tina invests $3,700 into an account with a 4.4% interest that is compounded quarterly. How much money will she have in
this account if she keeps it for 8 years?
Round your answer to the nearest cent.
DO NOT round until you have calculated the final answer.
Answer:
5250.96
Step-by-step explanation:
The 4.4% interest rate compounded quarterly means that you get 4.4%/4 four times a year. Over 8 years, that is 32 times. Since we use decimals, not percentages, we get
[tex]3700(1+0.044/4)^(4*8)=5250.96[/tex]

If the length of the shorter arc AB is 22 cm and C is the centre of the circle then the circumference of the circle is :
Answer:
The circumference of the circle is 176cm
Step-by-step explanation:
Step 1.
Figure out how many of those segments would fit in a whole circle
360/45=8
Step 2.
We know that the length of AB is 22cm so we multiply that by the number of segments in a whole circle
22×8=176

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 $___
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

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is miles per hour, with a standard deviation of miles per hour. 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.)
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.
⇒ About 68% of vehicles whose speeds are between 62 miles per hour and 70 miles per hour.

2. Charlie has a collection of marbles in three sizes, small, medium, and large. He has four times as
many small marbles as medium marbles. The number of large marbles is three more than five times
the number of medium marbles.
a. Write algebraic expressions to represent the number of small marbles, medium marbles, and
large marbles Charlie has. Write algebrauc expressions to represebt the number of small marbles, medium marbles, and large marbles charlie has.
Answer:
Step-by-step explanation:
The required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s and l = 3 + 5m.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the number of small marbles be s, medium marbles are m and large marble is l.
According to the question,
He has four times as many small marbles as medium marbles. The number of large marbles is three more than five times the number of medium marbles.
m = 4s
and
l = 3 + 5m
Thus, the required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s and l = 3 + 5m.

factorise 2tv+t-10v-5
and make the k the subject
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).
