Answer:
<h2>The area of the triangle ABC is 32 square inches.</h2>
Step-by-step explanation:
We know that the given triangle is a right-isosceles triangle, which means its leg are equal.
The area of a triangle is defined as
![A=\frac{1}{2}bh](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7Dbh)
Where
and
. Replacing values, we have
![A=\frac{1}{2} \times 8 \times 8 = 32 \ in^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%208%20%5Ctimes%208%20%3D%2032%20%5C%20in%5E%7B2%7D)
Therefore, the area of the triangle ABC is 32 square inches.
The student is not correct since the algebraic expression 1n + 13 translates to 1 times the sum of a number and 13.
The correct expression would be 9n + 13.
This is because it is 9 times a number and 13.
Meaning 9 times n (number) plus 13.
Answer:
The population of the country in 1907 was 501 million.
Step-by-step explanation:
Hi there!
The population is given by the function p(t)
We know that p(0) = 480 million and that p´(t) = 3.
p´(t) is the derivative of the function p(t) and expresses the variation (or rate of change) of the population with respect to "t". In this case, p´(t) = 3 indicates that the population increases by 3 million per year (because t is in years) from 1900 to 1910. Then, in 1907 the population will be:
480 million + 3 million / year · 7 year = 501 million.
Let's represent this unknown number with the variable 'n'
n + n + 2n + 4n = -104
Explanations:
'n+n' - a number plus itself
'+2n' - plus twice itself
'+4n' - plus 4 times itself
Anyway:
n + n + 2n + 4n = -104
Simplify:
8n = -104
Divide both sides by 8:
n = -13
The number is -13
Good luck! If you need me to explain something in more depth, just ask :))
-T.B.
The shape has sixty sides
working out:
180 - 174 = 6
360 / 6 = 60
