A = $1,120 B = $5120
Step-by-step explanation:
1.4/100 = 0.014
0.014 x 4000 = 56
1.4% interest on the $4,000 is $56.
56 x 20 (years) = 1,120
A= $1,120
To get B simply add 1,120 to 4000.

Suppose you borrow money for a year at a simple interest rate of 7.2%. You pay $86.40 in interest. How much have you borrowed?
Answers
Answer:
$1200
Step-by-step explanation:
You want to know the amount borrowed at 7.2% if the simple interest for one year is $86.40.
InterestThe interest formula is ...
I = Prt
where P is the amount borrowed, r is the interest rate, and t is the number of years.
ApplicationUsing the given values, we have ...
86.40 = P·0.072·1
P = 86.40/0.072 . . . . . . divide by the coefficient of P
P = 1200
You have borrowed $1200.
Answer: 1200
Step-by-step explanation: Linear equation. 7.2x = 100(86.40). then divide by 7.2 on each side. x=1200

Answers
Answer: the correct answer
Step-by-step explanation:
Theoretical probability of rolling of an even number is 0.4 or 40% of total rolling of six sided number cube.
What is theoretical probability?" Theoretical probability of an event is defined as the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = \(\frac{Number of favourable outcomes}{Total number of outcomes}\)
According to the question,
Total number of rolling a six sided number cube = 300
Number of possible outcomes of getting even number = 120
Number of possible outcomes of getting odd number = 180
Substitute the value in the given formula we get,
Required probability = (120) / ( 300)
= 0.4
= 40%
Hence, theoretical probability of rolling of an even number is 0.4 or 40% of total rolling of six sided number cube.

An equation is a mathematical statement that shows two mathematical expressions equal.
An equation consists a variable that does not have a fixed value to it.
Given,
j+12=25
Here ‘j’ is the variable.
To find ‘j’ we just need to 12 from 25.
So, 25 - 12 = 13
Hence, now we know that ‘j’ is equal to 13.
Proof :

andre is traveling from jeffersonville to springfield. he plans to stop for a break when the distance he has traveled and the distance he has left to travel have a ratio of 3:7. where should andre stop for his break? jeffersonville, J (-15, 2). springfield, S (25, 17)
Answers
Answer:
Andre should stop at (-3 , 6.5)
Step-by-step explanation:
The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3
The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

The average weight of five cats is 5.2 kg. The weights of four of the cats are 5.4 kg, 5 kg, 4.8 kg, and 4.9 kg. Find the weight of the fifth cat.
Answers
Answer:
5.9 kg
Step-by-step explanation:
Remember! To find the average of things, you add them al up and divide by how many things there are. This is an important detail that will help us solve the problem
It says the average is 5.2
This means ...
( weight of cat 1 + cat 2 + cat 3 + cat 4 + cat 5 ) ÷ 5 = 5.2
Let's plug in all of the values we know to find the weight of cat 5
( 5.4 + 5 + 4.8 + 4.9 + CAT 5 ) ÷ 5 = 5.2
Let's add all of this up and solve this!
( 20.1 + CAT 5 ) ÷ 5 = 5.2
multiply 5 by both sides so we can get the weight of cat 5 alone
20.1 + CAT 5 = 26
subtract
CAT 5 = 26 - 20.1
CAT 5 = 5.9
the weight of cat 5 is 5.9 kg
The weight of cat five is 5.9g
