11) Elsa took out a $2,200 loan with a 2-year term to buy a car at a 6% simple interest rate. How much will she have to pay IN INTEREST? *
Answer:
$264
Step-by-step explanation:
A 6% interest means that you have to pay 6% of the loan every period (which in this case is a year because it isn't stated anywhere). 6% of $2.200 is equal to $132, so for a loan of 2 years Elsa has to pay [tex]\$132 \cdot 2 = \$264[/tex], which is exactly what the question was asking for.

of her lawn. Her son mowed
1
4
of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answer:
Ms Rios mowed more
Step-by-step explanation:
I'm assuming that there's 100% of the lawn so if Ms Rios mowed 27% of the lawn when it was at 100% it would be at 73%
Now if her son mowed 14% and it was still at 100% it would be at 86%
So in the end Ms Rios mowed more of her lawn

Answer:
[tex]\sqrt{3}[/tex]
Step-by-step explanation:
See attachment 1. This is the formula to use.
There are two numbers, so n=2. Plugging them into the formula, you get
[tex]\sqrt[2]{6*\frac{1}{2}} \\[/tex]
Now, putting a 2 in front just means we're finding the square root, so I'll get rid of it. Then, just do the calculation.
[tex]\sqrt{6*\frac{1}{2}}=\sqrt{\frac{6}{2}}=\sqrt{3}[/tex]
Answer:
√3
Step-by-step explanation:
To find the Geometric mean, multiply the values given, then take the square root.
x² = ab
x= √ab
It's a "central tendency" we are calculating.
This is different from the arithmetical mean which uses addition and division to find that average.

The sum of three consecutive numbers is
42. Find the largest number in the set
Answer:
20
Step-by-step explanation:
Well consecutive numbers mean that the 3 numbers will follow each other in smallest to largest.
Example : 6, 7, 8 or 6,34,87
Non-Example : 7, 9, 6
As long as the number is greater than the one before it they are consecutive.
Following this rule I have come up with the numbers :
10, 12, 20
These three numbers are consecutive and equal to 42.
Now to find the largest number in this set just look at the greatest value which would be 20.
I don't have an entire explanation for this as I just did it in my head but I do hope it is correct.
I hope this helps! :)

Maia says that the lines in this system of linear eqations are parallel. is she correct? explain.
2x+y=14
2y+4x=14
Answer:
yes, they are parallel because their slopes are the same
Step-by-step explanation:
if you put each equation into slope-intercept form and compare slopes you can see whether they are parallel or not
2x + y = 14
y = -2x + 14
slope = -2
2y + 4x = 14
2y = -4x + 14
slope = -4/2, which simplifies to be -2

Determine whether each triangle with sides of given lengths is a right
triangle. Justify your answer. (Example 3)
30 cm, 122 cm, 125 cm

Answer:
It is not.
Step-by-step explanation:
The formula of a right triangle is "[tex]a^{2}+b^{2} =c^{2}[/tex]" where c is the hypothenuse (the longest side of the triangle) if we replace the formula with the values we will get
"[tex]30^{2} +122^{2} =125^{2} \\900 + 14884 = 15625\\15784\neq 15625[/tex]

Answer:
7/10
Step-by-step explanation:
1/10 = 2/20
1/4 = 5/20
2/5 = 8/20
11/20 = 11/20
We can see that the next term is just 11/20 + 3/20, as 3/20 is added onto each of the next terms.
11/20 + 3/20 = 14/20, which can be simplified to 7/10.

$318.75
$341.25
$337.88
The final cost of the stereo system after the discount and including the tax is $337.88. The correct option is D.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the regular price of a stereo system at Best Buy is $375. The system is on sale for 15% off the regular price. The sales tax rate is 6%.
The discounted price is calculated as,
Discounted Price = 375 x 0.85
Discounted Price = 318.75
The total price after sales tax is,
Total price = 318.75 x 1.06
Total price = $337.875
