Money was placed in a savings account and earned 3/4 % interest paid annually. Samantha, Tony and Anuyia each wrote an equation to show the amount of money in the account after one year with a balance of M dollars. T represents the total amount of money in the account.
Samantha’s Equation: T = 1.075M
Tony’s Equation: T = M + 0.0075M
Anuyia’s Equation: T = M(1 + 0.0075M)
Since none of the equations were written the same, they decided to see if their equations would give the same answers by using a $75 balance. Solve this problem using each student’s equation.

Answers
Answer:
x = 3
Step-by-step explanation:
These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:
(10x + 1) = (12x - 5)
Add 5 on both sides:
10x + 6 = 12x
Subtract 10x on both sides:
6 = 2x
Divide 2 on both sides:
3 = x
Answer:
(10x+1)°=(12x-5)°. [vertically opposite angle]
1+5=12x-10x
6= 2x
3=x
therefore,x=3

The dot plots below show the scores for a group of students who took two rounds of a quiz:
Which of the following inferences can be made using the dot plot?
The range of each round is the same.
There is no overlap between the data.
Round 1 scores were higher than round 2 scores.
Round 2 scores were lower than round 1 scores.
Answers
Because the range is the highest number minus the lowestAnswer: The range of each round is the same.
Step-by-step: Because the range is the highest number minus the smallest number so for round one that would be 8-5 Which is three and for round two 9-6 which is also three.
Answer:
A) the range of each round is the same
Step-by-step explanation:
The lengths of two sides of a right angled triangle are 20 cm and 30 cm.
Calculate the length of the third side, if it is:
(a) the hypotenuse
(b) not the hypotenuse
Answers
Answers:
Part (a) 10*sqrt(13) Part (b) 10*sqrt(5)Those values are exact. They approximate to:
10*sqrt(13) = 36.0555
10*sqrt(5) = 22.3607
====================================================
Explanation:
Part (a)
If the unknown third side is the hypotenuse then we need to find the value of c when a = 20 and b = 30.
Apply the pythagorean theorem
a^2 + b^2 = c^2
20^2 + 30^2 = c^2
400 + 900 = c^2
1300 = c^2
c^2 = 1300
c = sqrt(1300)
c = sqrt(100*13)
c = sqrt(100)*sqrt(13)
c = 10*sqrt(13) .... exact length
c = 36.0555 ...... approximate length
------------------------------------
Part (b)
If the third side is not the hypotenuse then that must mean c = 30 is the hypotenuse as this side is larger than the 20 cm side. The hypotenuse is always the longest side.
Let a = 20 be the known leg. Let's find the other unknown leg b using the pythagorean theorem.
a^2 + b^2 = c^2
20^2 + b^2 = 30^2
400 + b^2 = 900
b^2 = 900-400
b^2 = 500
b = sqrt(500)
b = sqrt(100*5)
b = sqrt(100)*sqrt(5)
b = 10*sqrt(5) ..... exact length
b = 22.3607 ....... approximate length

NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
Answers
Answer:
A = (1/2)Pa = Pa/2
You can multiply both sides by 2 to eliminate the fraction on the right side:
2A = 2(Pa/2) = Pa
Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:
(2A)(1/a) = 2A/a = (Pa)(1/a) = P
Rewriting:
P = 2A/a
You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.
