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.

20 fans at a 49ers game are asked what their favorite team is.
Answer:
4) Unbiased; 5) Biased
Step-by-step explanation:
4) states that the audience of the poll was "random" people meaning it's a good foundation of data as they weren't chosen for the employee noticing their specific affiliation with being overjoyed with the product (as the question doesn't say) or for not liking (have complaints about it) the product.
5) The audience of the poll is fans of a sports team--definitely biased because they'll say they love the 49ers being a fan for them. Leads to skewed results not representing a portion of a population accurately.

Solve for x.
x/9 = -5
Find the value of x:
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

It takes the Pluto about 14.375 x 10¹⁰ years to orbit the Sun while the Sun completes one orbit around the Milky Way
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
It takes the Sun about 2.3x10⁸ years to orbit the center of the Milky Way.
It takes Pluto about 2.5 times 10 squared years to orbit the Sun.
Pluto orbits the Sun while the Sun completes one orbit around the Milky Way,
= 2.3 x 10⁸ x (2.5 x 10)²
= 14.375 x 10¹⁰
Therefore, the required time is 14.375 x 10¹⁰ years.

Find the missing side length of the right triangle
using the Pythagorean Theorem or PT converse.
A) 32 cm
B) 21 cm
C) 73 cm
D) 56 cm
Answer:
The answer is D) 56 cm
Step-by-step explanation:
Using the Pythagorean Theorem, you would first have to multiply 65 x 65 to get 4225 and multiply 33 x 33 to get 1089. Then, for the last step, you will have to solve this little equation: 4225= 1089 +? To do this, you will have to subtract 4225 - 1089 = 3136. Finding the square root, you will finally get your answer of 56 cm.

Write a function rule for "The output is two more than one-fourth of the input ."
Answer:
y=(x/4)+2
Step-by-step explanation:
let y be the output and x be the input. So,
y=(x/4)+2
The function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.
What is function?A function is a relation between a dependent and independent variable. We can write the example of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is to find the function rule for "The output is two more than one-fourth of the input."
The given mathematical statement is - "The output is two more than one-fourth of the input."
Assume the input to be {x} and the output be {y}. So, we can write that -
(output) = (two) + (1/4)(input)
y = 2 + (1/4)x
Therefore, the function rule for " The output is two more than one-fourth of the input " is y = 2 + (1/4)x.
