Answer:
2√3
Step-by-step explanation:
In a special right triangle called the 30-60-90 triangle, the ratios of the side lengths are x-x√3- 2x respectively. This means that the side opposite to the 60 degrees is x√3 and the side opposite to the 30 degrees is x.
Since the side opposite to the 60 degrees is 6, x√3=6
x√3=6
x=6/√3
rationalize the denominator:
6√3/3

2√3
so the answer is the third one. 2√3

Find the area of the region bounded by the line y=3x-6 and line y=-2x+8. For each of the given situations, find the AREA of the bounded region, the answer is not A, B, C, or D, I need to solve the answer for that case. (For example, C, it says the line y=6. I need you to find the area of the bounded region when the line y is 6 and intersects the 2 other lines.)
B: the y-axis.
C: the line y=6
Answer:
Step-by-step explanation:
You've omitted A and D.
Find the points of intersection.
y = 3x-6 and y = -2x+8 intersect at (2.8,2.4)
B:
The y-axis and y = 3x-6 intersect at (0,-6).
The y-axis and y = -2x+8 intersect at (0,8)
You have a triangle with base = 14 and height = 2.8
Area = 19.6 sq units
C:
y=6 and y = 3x-6 intersect at (4,6)
y=6 and y = -2x+8 intersect at (1,6)
You have a triangle with base = 3 and height = 6-2.4 = 3.6
area = 5.4 sq units

You deposit $650 in a savings account. How long does it take an account with an annual interest rate of 5% to earn $178.25 in interest? Round your answer to the nearest tenth.
Answer:
about 5 years 6 months
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
t = 178.25 / ( 650 × 0.05 ) = 5.4846
t = 5.4846 years
The time required to
accumulate simple interest of $ 178.25
from a principal of $ 650.00
at an interest rate of 5% per year
is 5.4846 years (about 5 years 6 months).

Madison read 1/2 of a book in the morning, and she read some more at night. By the end of the day she still had 2/5 of the book left to read. How much of the book did Madison read at night?
Answer: 1/10
Step-by-step explanation:
At the end of the day, she still had 2/5 of the book to read. Which meant that she had read 3/5 of the book. Since she read 1/2 of the book in the day, we would read 3/5 - 1/2 = 6/10 - 5/10 = 1/10 of the book at night.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of campers who voted for hot dogs = 5 campers
Let the number of campers who voted for sphagetti = 4 campers
Now , the total campers = 5 + 4
= 9 campers
5 out of 9 campers vote for hot dogs
So ,
The total number of campers = 72 campers
The equation will be ,
The total number of campers who voted for hotdogs =
( number of campers who voted for hot dogs / the total campers ) x 72
The total number of campers who voted for hotdogs = ( 5 / 9 ) x 72
= 5 x 8
The total number of campers who voted for hotdogs = 40 campers
Hence , The number of campers who voted for hotdogs is 40 campers

Point: (4, -6)
Slope: 2
Please show me how to do this, thanks.
Answer:
y=2x-14
Step-by-step explanation:
y=mx+b(m is slope)
we know
y=2x+b
so if you plug in the values for the points you get
-6=4(2)+b
-6=8+b
b=-14
so then the complete equation would be
y=2x-14

2 9/14
Step-by-step explanation:
first we must make 1/6 and 3/7 have common demoniaters! (or however u spell it)
1/6 x 7/7 = 7/42
3/7 x 6/6 = 18/42
7/42 + 18/42 = 25/42
2/7 x 6/6 = 12/42
25/42 + 12/42 = 37/42
37/42 + 7/42 = 44/42
44/42 + 18/42 = 62/42
62/42 + 12/42 = 74/42
5/7 x 6/6 = 30/42
74/42 + 30/42 = 104/42
104/42+7/42 = 111/42
111/42 = 2 9/14

A "greater than or equal to" sign means that your line will have a closed, or filled in circle. Knowing this, we can eliminate all of the open circle options.
If our numbers are negative, a number "greater than" a negative would be closer to or positive. I would choose the filled in circle pointing towards the right, given this information.

The value V (in dollars) of a vehicle depends on the miles x that it has been driven. This is given in the formula V = 22,000 – 0.25x . After one year, the value of a vehicle is between $12,000 and $15,000.
Which range of miles driven corresponds to this range of values based on the given formula?
Answer:
(28000,40000) or $28,000 to $40,000
Step-by-step explanation:
plug in values as V and solve for x:
12,000=22,000-0.25x
-10,000=-0.25x
40,000=x
15,000=22,000-0.25x
-7,000=-0.25x
28,000=x
an interval notation always has the lower value first so its:
(28000,40000) or $28,000 to $40,000
