The area of triangle is 72.62 square meters.
What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
The sides of triangle are
a = 20 meters, b = 10 meters, c = 15 meters
The formula of area of triangle is
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex], where
[tex]s=\frac{a+b+c}{2}[/tex]
Now, calculate s as
[tex]s=\frac{20+10+15}{2}[/tex]
⇒ [tex]s=\frac{45}{2}[/tex]
⇒ [tex]s=22.5[/tex]
Thus area of triangle is
⇒ [tex]A=\sqrt{22.5(22.5-20)(22.5-10)(22.5-15)}[/tex]
⇒ [tex]A=\sqrt{22.5(2.5)(-12.5)(-7.5)}[/tex]
⇒ [tex]A=\sqrt{5273.4375}[/tex]
⇒ [tex]A=72.618[/tex] ≈ [tex]72.62[/tex]
Hence we can conclude that the area of triangle is 72.62 square meters.

In a classroom of 28 students, 12 students are girls. If a student is selected randomly, what is the probability that the student is a boy?
Answer:
Step-by-step explanation:
28 total students
12 are girls
16 are boys
the question is, what percent of 28 is 16
b/c that's how likely it would be to pick a boy in a random pick
16/28=0.571428
so about 57 %
or 57 out of 100
Answer: 16/28 or 8/14 or 57%
* they all are equal so it doesn’t matter with of the three you pick *
Steps:
28 - 12 = 16
16/28 = .5714
57.14%

Identify the y coordinate for the solution to the system of equations. Solve the system using substitution.
y=2x-11
4x + 3y =-13
Answer:
(2,-7)
Step-by-step explanation:
Plug the first equation into the second equation.
4x+3(2x-11)=-13
4x+6x-33=-13
10x=20
x=2
Now, plug the value of x into one of the equations in order to find y.
y=2(2)-11
y=4-11
y=-7

If I was asked to think of a number and multiply it by 2, I could
write this algebraically as 2x.
Write the following algebraically, using x as your unknown.
"I think of a number, multiply it by 2, subtract 3 and multiply the result by 4."
Answer:
4(2x - 3) is how I would write it algebraically.
Step-by-step explanation:
The number is x, as it is unknown. 2x means you multiply the unknown number by 2.
2x
Now, you subtract 3.
2x - 3
And then you multiply the result of that by 4, hence the parentheses.
4(2x - 3)
To solve, just distribute 4. 4*2x = 8x. 4*-3 = -12.
8x - 12
Answer:
8x-12
Step-by-step explanation:
(2x-3)* 4 = 8x-12

6. Meena’s family had a pizza for dinner. The pizza was cut into 8 equal pieces. Meena ate 1 piece, her brother ate 2 pieces, and her mother ate 3 pieces. a) What fraction of the pizza did Meena eat? Her brother eat? Her mother eat? b) Which person’s fraction can you write in more than one way? Explain. c) What fraction of the pizza was eaten? What fraction was left?
Answer: Meena ate 1/8. Her brother ate 2/8, and her mom ate 3/8ths of the pizza. Her brother can be simplified from 2/8 to 1/4. Lastly, 6/8ths of the pizza has been eaten. 2/8ths is all that remains.

Answer:
4.718592
Step-by-step explanation:
To get to -14.4 from 18 you multiply 18 x 0.8
Repeat that until you get to the 7th term
18 (1st)
18 x 0.8 = -14.4 (2nd)
-14.4 x 0.8 = 11.52 (3rd)
11.52 x 0.8 = 9.216 (4th)
9.216 x 0.8 = 7.3728 (5th)
7.3728 x 0.8 = 5.89824 (6th)
5.89824 x 0.8 = 4.718592 (7th)

Answer:
6. C multiply the first equation by -7 ...
7. A parallel lines
Step-by-step explanation:
6. The idea of elimination is to create equations that have opposite coefficients for one of the variables. In this set of equations, there are two simple ways to achieve that.
On is to multiply the second equation by -2 (so x-coefficients are 4 in the first equation and -4 in the second equation).
The other is to multiply the first equation by -7 (so y-coefficients are -7 in the first equation and +7 in the second equation).
This latter method is described in answer choice C.
__
7. Equations are more easily compared if they are in the same form. Here, "standard form" is nice. To put the second equation in standard form, we must remove a factor of 3 from all of the numbers:
3(2x) +3(y) = 3(4)
2x +y = 4
We see that this differs from the first equation only in that it has a different right-side constant. That means it describes a parallel line.
Order these numbers from least to greatest.
