Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They substitute their values shown below into the compound interest formula.
The question is incomplete. The complete question is :
Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They substitute their values shown below into the compound interest formula. Compound Interest Accounts Name Principal Interest Rate Number of Years Compounded Jaina $300 7% 3 Once a year Tomas $400 4% 3 Once a year. Which pair of equations would correctly calculate their compound interests?
Solution :
It is given that Jaina and Tomas wants to open an account by depositing a principal amount for a period of 3 years and wanted to calculate the amount they will have using the compound interest formula.
So for Jiana :
Principal, P = $300
Rate of interest, r = 7%
Time, t = 3
Compounded yearly
Therefore, using compound interest formula, we get
[tex]$A=P\left(1+\frac{r}{100}\right)^{t}$[/tex]
[tex]$=300\left(1+\frac{7}{100}\right)^{3}$[/tex]
[tex]$=300(1+0.07)^3$[/tex]
Now for Tomas :
Principal, P = $400
Rate of interest, r = 4%
Time, t = 3
Compounded yearly
Therefore, using compound interest formula, we get
[tex]$A=P\left(1+\frac{r}{100}\right)^{t}$[/tex]
[tex]$=400\left(1+\frac{4}{100}\right)^{3}$[/tex]
[tex]$=400(1+0.04)^3$[/tex]
Therefore, the pair of equations that would correctly calculate the compound interests for Jaina is [tex]$A=300(1+0.07)^3$[/tex] .
And the pair of equations that would correctly calculate the compound interests for Tomas is [tex]$A=400(1+0.04)^3$[/tex] .

Answer:
1/3 is the probaility
Step-by-step explanation:
since there are 3 different socks the answer would be 1/3
Answer:
The probability of her pulling of a blue sock the first time is 6 out of 12

Answer:
x = 63°
it is an isosceles triangle, so K and M are equal
Step-by-step explanation:
let K be x, since K=M means both equals x
x + x + 54° = 180°
2x + 54° = 180°
2x = 180° minus 54°
2x = 126°
x = 63°
to prove
63° + 63° + 54° = 180°

Given the triangle below with vertices A(4,3) B(-2,3) and C(-1,-2). Find the area and perimeter
Answer:
12.5 sq units. Explanation: Area of a triangle with vertices (x1,y1),(x2,y2),(x3,y3) is 12[x1(y2−y3)+x2(y3−y1)+x3(y1−y2)]. Using this formula ...
Step-by-step explanation:

The value of the area of circle is,
Area = 15 units²
And, The value of perimeter is,
⇒ 6 + √34 + 5√2 Units
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle with vertices A(4, 3) B(-2, 3) and C(-1, - 2).
Now, We know that;
Area of triangle with vertices (x₁, y₁) (x₂, y₂) and (x₃, y₃) is,
= 1/2 [ x₁ (y₂ - y₃) + x₂ (y₃ - y₁) + x₃(y₁ - y₂) ]
Hence, We get;
The value of the area of circle is,
Area = 1/2 [ 4 (3 + 2) - 2 (- 2 - 3) - 1 (3 - 3) ]
Area = 1/2 [ 20 + 10 ]
Area = 1/2 x 30
Area = 15 units²
We know that;
The distance between two points (x₁ , y₁) and (x₂, y₂) is,
⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²
Hence, Lenght of AB is,
AB = √ (- 2 - 4)² + (3 - 3)²
AB = √- 6²
AB = 6
BC = √ (- 2 - 1)² + (3 + 2)²
BC = √9 + 25
BC = √34
CA = √ (- 1 - 4)² + (- 2 - 3)²
CA = √25 + 25
CA = √ 50
CA = 5√2
Thus, The perimeter of triangle is,
⇒ AB + BC + CA
⇒ 6 + √34 + 5√2

Find the length of arc AB. Use 3.14 for pi. Round to the nearest tenth.
Answer:
arc AB = 12.40°
Step-by-step explanation:
diameter = 7.9 x 2 = 15.8
circumference = 15.8 x 3.14 = 49.612
since the central angle of arc AB is 90 °
90/360 x 49.612 = 12.40

At a zoological garden, 3 people ride the tram for every 4 people who don't ride it. Write the ratio of people who ride the tram to all people in three ways. Write the ratio of all people to people who don't ride the tram in three ways. Write the ratio of people who ride the tram to all people in three ways.
Answer:
= 3 to 7
= 3 : 7
= 3/7
Step-by-step explanation:
Number of people who ride the tram = 3
Number of people who does not ride the tram = 4
Total people = 3 + 4 = 7
Ratio of people who ride the tram to all people in three ways.
= 3 to 7
= 3 : 7
= 3/7
Ratio of all people to people who don't ride the tram in three ways.
= 7 to 4
= 7 : 4
= 7/4
Ratio of people who ride the tram to all people in three ways.
= 3 to 7
= 3 : 7
= 3/7

Find the change between the first two sets:
12-9 = 3
14.4 - 10.8 = 3.6
3.6/3 = 1.2
Now find the change between the last two sets:
12 - -3 = 15
14.4 - 3.6 = 10.8
10.8/15 = 0.72
1.2 does not equal 0.72 so the answer is No

The following are the ages (years) of 5 people in a room:
23, 20, 15, 12, 17
A person enters the room.
The mean age of the 6 people is now 19.
What is the age of the person who entered the room?
Answer:
multiply 6 by 19 to get the total age of the six people in the room then add the ages of the 5 people in the room and subtract it from the total of the 6 to get your answer
Answer:
27
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let x be the age of the person entering the room , then
[tex]\frac{23+20+15+12+17+x}{6}[/tex] = 19 ( multiply both sides by 6 )
87 + x = 114 ( subtract 87 from both sides )
x = 27
The age of the person who entered the room is 27

A) 13 more than half of 6 more than the quotient of 6 and 2
B) 13 more than half of the quotient of 6 and 6 minus 2
C) Half of 13 multiplied by the quotient of 6 and 2 plus 3
D) 13 plus half of 6 divided by 2, then subtract 6
Answer: It's A.
Step-by-step explanation:
I did the test and I got it right
The expression should be described option A. A) 13 more than half of 6 more than the quotient of 6 and 2
Description of an expression:
Since the expression is 13 + fraction 1/2 x (6 ÷ 2 + 6)
So we can explained that 13 should be more than the half of 6 i.e. more than the quotient of 6 and 2.
Therefore, the option A is correct.
And, the rest of the options are wrong.

If x=8 and y=−3, evaluate the following expression:6x−8y
Answer:
72
Step-by-step explanation:
here's your solution
=> x= 8
=> y= -3
=> putting the value
=> 8*6 - (8*-3)
=> 48 + 24
=> 72

Hey there!
If x = 8 and y = -3, then SUBSTITUTE it into the equation
6(8) - 8(-3)
6(8) = 48
48 - 8(-3)
8(-3) = -24
48 - (-24)
