hi!!! what’s the area and formula for this problem??
Answer:
134.28 m²
Step-by-step explanation:
I suppose this is an isosceles triangle
tan 75° = 2 + √3 = 3.73 = h / 6 (h: height and 6 = 12/2, 1/2 of base)
h = 6 x 3.73 = 22.38
Area = (12 x 22.38) / 2 = 134.28
You often go to school by bus. You have two bus systems you could take. City Bus offers a monthly pass that costs $15 and then you pay $1 per ride. Campus Transport simply charges $2.50 per ride and does not require a monthly pass. After how many rides will the total costs of the two options be the same? Write a system of equations in order to solve this problem.
Answer:
For City Bus you will need to ride 10 times for 2 months, and for Campus Transport you need to ride 16 times.
Step-by-step explanation:
$2.50 x 2 = $5.00 so you know that the number of rides needs to even in order to have a whole number. This is because there is no way the City Bus cost will ever have cents.
$2.50 x 16 = $40.00
$15 x 2 = $30
$1 x 10 = $10
$30 + $10 = $40
So (15 x 2) + (10 x 1) = 16 x 2.50

Answer:
x = 14.5
Step-by-step explanation:
The diagonals of a rhombus are at right angle to each other, then
∠ BOA = 90° , so
6x + 3 = 90 ( subtract 3 from both sides )
6x = 87 ( divide both sides by 6 )
x = 14.5

1. Bill decided to buy six books on history instead
of four books on politics. It follows, then, that
the opportunity cost of each history book was ______
books on politics.
Answer: 2/3 books on politics
Step-by-step explanation:
The opportunity cost of something is the next best alternative that you would have taken if you did not instead go for the option that you took.
Opportunity cost here is the number of books on politics that Bill had to give up to get a single book on history.
= Number of politics books / Number of history books
= 4 / 6
= 2/3 books on politics
Bill gave up 2/3 books on politics to get a single history book.

Anna opened a savings account and deposited $300.00 as principal. The account earns 1%
interest, compounded annually. What is the balance after 2 years?
Answer:
$6
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1%/100 = 0.01 per year,
then, solving our equation
I = 300 × 0.01 × 2 = 6
I = $ 6.00
The simple interest accumulated
on a principal of $ 300.00
at a rate of 1% per year
for 2 years is $ 6.00.

What is (15x + 7) + (-11x – 2)?
Answer:
4x + 5
Step-by-step explanation:
After solving the given equation, the value obtained for x will be equal to -5/4.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given expression in the question,
(15x + 7) + (-11x - 2)
15x + 7 -11x - 2
4x + 5
Now, solve it for x,
4x = -5
x = -5/4
