Se necesita instalar el piso de una habitacion de forma rectangular cuyas dimensiones son 7 m por 8 m.
Costo por m2= $20.000
Primero debemos calcular el total de metros cuadrados de la habitación:
Totalm2= 7*8= 56m2
Ahora el costo total:
Costo total= 56*20.000
Costo total= $1.120.000
Solve the following equation for y, and then identify the slope of the line: 5x + 9y = 8.

AND THEN ONCE U HAVE THE ANSWER
FIND THE LENGTH OF AC
Answer:
AC=18
Step-by-step explanation:
To find AC, use the Pythagorean Theorem. Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b². 12²-8²=b²
144-64=b²
80=b²
√80=√b²
8.94427191=b
That is for one of the two right triangles that make up the tent. Since there are 2 triangles, 8.94427191 only equals BC or AB. So, multiply 8.94427191×2=17.88854382 to find the length of AC.
AC= 18

I need help quick. Please help I don’t understand.
Answer:
C
Step-by-step explanation:
The y-intercept of the line is -4, immediately eliminating D. The two definite points on the graph I could visually confirm were (0,-4) and (1, -1). You had to "rise" 3 units and "run" 1 unit. This is a slope of 3/1 or 3. In y=mx+b form, The equation is f(x)=3x-4 or C.

HELP PLEASE!!
Answer:
x = 16
Step-by-step explanation:
hypotenuse= a /sin(α)
= 22.62742
= 16√2
So using this to calculate x:
x = √c2 - a2
= √22.627416997972 - 162
= √256
= 16

A total of 228 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
Answer:
152
Step-by-step explanation:
Let x be the number of children tickets sold
2x+x=228
combine like terms
3x=228
x=76
adult tickets is two times the amount of x
2x=152

solve the system through elimination
Answer:
x=3
y=1
Step-by-step explanation:
-2x - 7y = -13
3x + 6y = 15
3(-2x - 7y = -13) = -6x - 21y = -39
2(3x + 6y = 15) = 6x + 12y = 30
-6x - 21y = -39
---------------------- The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9
6x + 12y = 30
Therefore, you can say that -9y = -9 so y = 1
FInally, plug that back into either one of the original equations:
3x + 6(1) =15
3x = 9
x = 3
Help please
I need to pass my class
Answer:
look below
Step-by-step explanation:
thing to note:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
opposite= side across angle you are using
hypotenuse= side across 90 degree angle
adjacent= remaining side
angle B
sin = 6/10
cos = 8/10
tan = 6/8
angle C
sin = 8/10
cos = 6/10
tan = 8/6
hope that helped. let me know if you have any questions:)
