Answer: 60
Step-by-step explanation:
Using Heron's formula, we know that
Step 1: Calculate "s" (half of the triangles perimeter):
s = (a+b+c)/2
Step 2: Then calculate the Area:
Herons formula A = sqrt( s(s-a)(s-b)(s-c) )
So S = 36/2 = 18
so [tex]\sqrt{18(18-13)(18-13)(18-10)}[/tex]
So our final answer is the square root of 3600, which equals 60.

Answer:
4?
Step-by-step explanation:
So, at from x 0 to x 2, y goes up 4
Answer:
2
Step-by-step explanation:
The rate of change is defined by [tex]\frac{Rise}{Run}[/tex] , [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1}}[/tex]. or [tex]\frac{Delta y}{Delta x}[/tex].
For your question, the points are (0,4) and (2,8).
Plugging these points into the formula:
[tex]\frac{8-4}{2-8}[/tex]
After calculations, you would end up with [tex]\frac{4}{2}[/tex] or 2.
11/12-?=2/3 How do I get the missing fraction with out reducing?
Step-by-step explanation:
11/12-?=2/3
11/12-2/3=?
11-8/12=?
3/12
=1/4
Answer:
? = 1/4
Step-by-step explanation:
11 / 12 - ? = 2 / 3
move constant at Right hand side and change its sign.- ? = 2/3 - 11/12
subtract the fractions- ? = - 1/4
change the sign of both side of equation? = 1/4

Given angel theta with cos theta < 0 and sin theta > 0, indicate the quadrant that theta lies in
bearing in mind that cos(θ) < 0, is just another way to say that cos(θ) is negative, and sin(θ) > 0, is just another way to say that sin(θ) is positive.

¿Cuántos quilómetros recorrerá una locomotora en 5 horas, si marcha a una velocidad de 82 kilómetros
por hora?
Step-by-step explanation:
Datos;
una locomotora
recorre 5 horas
a una velocidad de 82 km/h
Se asume que la locomotora lleva un movimiento rectilíneo uniforme.
Su recorrido esta descrito por la siguiente ecuación de posición;
x = x₀+ v · t
x-x₀ = d = v · t
siendo;
d = distancia recorrida
v = 82 km/h
t = 5 horas
Sustituir:
d = (82)(5)
d = 410 km
82km/h * 5h= 410km
La locomotora recorrerá 410km
hi so the problem is a recipe calls for a total of 3 2/3 cups of flour and sugar. If the recipe calls for 1/4 cup of sugar, how much flour is needed
1. 3 1/12
2. 3 1/4
3. 5/12
4. 3 11/12
Answer:
3 5/12 cups of flour are needed
Step-by-step explanation:
The flour-sugar total is 3 2/3 cups, of which 1/4 cup is sugar. So, to find the amount of flour used, we subtract 1/4 cup (sugar) from the total (3 2/3 cups):
11 1
----- - ---- where 11/3 is the improper fraction form of 3 2/3
3 4
The LCD is 12. Rewriting this subtraction using the LCD, we get:
44 3
---- - ----- = 41/12 (cups) = 3 5/12 cups
12 12
3 5/12 cups of flour are needed

What value of x makes this proportion true?
3/x = 15/40
A. 5
B. 28
C. 8
D. 105
Answer:
here the value of X should be 8 to make this proportion true
3/8=15/40
by cross multiplying
15*8=40*3
120=120
therefore the option C is correct

Step-by-step explanation:
10x+2=9x+18
-2 -2
10x=9x+16
-9x -9x
x=16
Hope this helps! :)
Answer:
x = 16°
Step-by-step explanation:
(10x + 2)° = (9x + 18)°
10x + 2 = 9x + 18
10x + 2 - 2 = 9x + 18 - 2
10x = 9x + 16
10x - 9x = 9x - 9x + 16
x = 16°

Carroll bikes 1 kilometer east, 4 kilometers north, and then 5 kilometers east again. How far is Carroll from her starting position?
Answer:
10.5 km
Step-by-step explanation:
this can be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
1² + 4² =
1 + 16 = 17
√17 = 4.123km
4² + 5²
16 + 25 = 41
√41 = 6.40 KM
total distance = 6.4 + 4.12 = 10.52

We have
Angle ORQ
we use the Thales theory
From the formulae
A²+B²=C²
consider
A=OR
B=RQ
C=OQ
so
48²+64²=C²
2304+4096=C²
6400=C²
(6400)¹/²=(C²)¹/²
80=C
But
C=OQ
《OQ=80
The equation of a linear function in point-slope form is y – y1 = m(x – x1). Harold correctly wrote the equation y = 3(x – 7) using a point and the slope. Which point did Harold use?
(7, 3)
(0, 7)
(7, 0)
(3, 7)
Answer:
The point is (7,0).
Step-by-step explanation:
The equation of a linear function in point-slope form is as follows :
[tex]y-y_1=m(x-x_1)[/tex] ...(1)
Where
(x₁,y₁) are the coordinates of the point which the line passes through it and (x,y).
Harold correctly wrote the equation y= 3(x–7)
or we can write it as :
y-0=3(x-7) ...(2)
Comparing equations (1) and (2), we get :
x₁ = 7 and y₁ = 0
So, the point is (7,0).
The correct option is (c).
Answer:
C

A chef got 9 bags of onions. The red onions came in bags of 6 and the yellow onions came in bags of 7. If the chef got a total of 59 onions, how many bags of each type of onion did he get?
Answer:
yellow = 5 bags
red = 4 bags
Step-by-step explanation:
two equations can be derived from the question
x + y = 9 equation 1
6x + 7y = 59 equation 2
where x = number of red onion bags
y = number of yellow onion bags
Multiply equation 1 by 6
6x + 6y = 54 equation 3
subtract equation 3 from 2
y = 5
substitute for y in equation 1
x + 5 = 9
x = 9 - 5
x = 4
3x-6y=24 y=Mx+b form
What is the answer for 2(n-1)+4n=2(3n-1)
Answer:
No solution
Step-by-step explanation:
2(n-1)+4n=2(3n-1)
2n-2+4n=6n-2
6n-2=6n-2
No solution
Answer:
0
Step-by-step explanation:
2(n-1)+4n=2(3n-1)
2n - 2 + 4n = 6n - 2
2n + 4n - 2 = 6n - 2
6n - 2 = 6n - 2

A music store originally purchased a piano at a cost of $892.03 and marked it up 125%. After a few weeks,
however, the store discounted the piano 50% in order to make room for new merchandise. What was the
discounted price?
Answer:
$557.52
Step-by-step explanation:
Solve for marked up price:
892.03 × 1.25
1115.0375
Solve for discounted price:
1115.0375 × 0.50
557.51875
Round up to nearest hundredths place:
557.52
Your answer may vary depending on if you rounded your first answer (1115.0375), but it should be only a decimal or two off from my final answer.

g(x) = [tex]-\frac{2}{5} (10)^{x}[/tex]
Step-by-step explanation:
Looking at the equation of a Exponential Function:
[tex]y= a(b)^{[k(x-h)]}+c[/tex]The a-value [tex](\frac{2}{5})[/tex] determines whether the function reflects over the x-axis. If it's negative it reflects over the x-axis. If it's positive it stays over the x-axis.
