I can't find Y, please help!
Answer:
x = 50 and y = 10
Step-by-step explanation:
The drawing shows several equal sides. The triangles are a reflection of each other, so their angles will be the same.
Take the top and bottom angles:
2x + 5 and 3x - 45
They are equal, so:
2x + 5 = 3x - 45
-x = -50
x = 50
The angle y will have the same value as the one below it in the bottom triangle. Add the angles in the lower triangle and since the sum of the angles in a triangle is always 180, we can say:
y + (8y-15) + (3x-45) = 180
Rearrange:
y = 180 - (8y-15) - (3x-45)
y = 180 - 8y + 15 - 3x + 45
9y = 180 + 15 - 3x + 45
Since x = 50:
9y = 180 + 15 - 3*(50) + 45
9y = 180 + 15 - 150 + 45
9y = 90
y = 10

3x-6y=2 and 4x-6y=2 solve by substitution
first you have to choose one of the equations and isolate one of the variables
3x - 6y = 2
-6y = 2 - 3x
y = 2/-6 + 1/2
then you have to substitute it in the other equation
4x-6(2/-6 + 1/2) = 2
4x + 2 - 3 = 2
4x - 1 = 2
4x = 3
x = 3/4
after that you solve for y
3 (3/4) - 6y = 2
9/4 - 6y = 2
-6y= - 1/4
y= 24
THIS MAY NOT BE RIGHT BTW
is this correct????????
Answer:
its half way correct. get rid of the dot on the 2.
Step-by-step explanation:
the point (2, -6) is where the dot is supposed to be located. the 2 is the x point. and the -6 is the y point. so u go to the right 2 and then u go down 6. so the point is where the lowest dot is located
It takes 5 builders 3 1/2 hours to build a wall. How many hours will it take for 2 builders to build an identical wall?.
Answer:
8.75 hours for 2 builders so complete it
Step-by-step explanation:
its right because im smart and i say its right
If it takes 5 builders [tex]3\frac{1}{2}[/tex] hours to build a wall, it will take 2 builders [tex]8\frac{3}{4}[/tex] hours to build an identical wall
The time taken for 5 builders to build the wall = [tex]3\frac{1}{2}[/tex] hours
The time take for 5 builders to build the wall = 3.5 hours
Time taken for 1 builder to build an identical wall =
5 x (Time taken for 5 builders to build the wall)
Time taken for 1 builder to build the wall = 5 x 3.5
Time taken for 1 builder to build the wall = 17.5 hours
Time taken for 2 builders to build an identical wall = (Time taken for 1 builder)/2
Time taken for 2 builders to build an identical wall = 17.5/2
Time taken for 2 builders to build an identical wall = 8.75 hours
Time taken for 2 builders to build an identical wall = [tex]8\frac{3}{4}[/tex] hours

Calculate the frequency of a wave with a speed of 130 m/s and a wavelength of 2.5
Answer:
52 Hz
Step-by-step explanation:
We can divide the speed by the wavelength to find the number of waves propagated in one second:
(130 m/s)/(2.5 m/wave) = 52 waves/s
The SI unit of frequency is the Hertz, equal to one cycle per second.
The frequency of this wave is 52 Hz.
_____
Additional comment
The use of the unit Hz to signify frequency was adopted in 1933, but did not replace the unit "cycles per second" (CPS) until a number of years later.

How fast is the area of a square increasing when
the side is 3 m in length and growing at a rate of
0.8 m/min?
A. 4.8 m2 /min
B. 1.875 m²/min
C. 3.25 m2 /min
D. 5.5 m² /min
Using implicit differentiation, it is found that the area of the square is increasing at a rate of:
A. 4.8 m²/minThe area of a square of side length l is given by:
[tex]A = l^2[/tex]
Applying implicit differentiation, the rate of change is given by:
[tex]\frac{dA}{dt} = 2l\frac{dl}{dt}[/tex]
The side is 3 m in length, hence [tex]l = 3[/tex].Growing at a rate of 0.8 m/min, hence [tex]\frac{dl}{dt} = 0.8[/tex]Then:
[tex]\frac{dA}{dt} = 2l\frac{dl}{dt} = 2(3)(0.8) = 4.8[/tex]
Hence, option A is correct.

One angle of an isosceles triangle measures 34º. Which other angles could be in that
isosceles triangle?
Answer:
112º and 73º
Step-by-step explanation:
34º could be base angle
Base angles are equivalent
Vertical angle would be = 180 - 34 - 34
Vertical angle = 112º
34º could be vertical angle
Base angles are equivalent
2x = 180 - 34
Base angle = 73º

What is the slope of (-3, -2) and (-1, -5) ??
Answer:
-3/2 or -1 1/2
Step-by-step explanation:
The slope, plugging into the equation (y_2-y_1)/(x_2-x_1) would be -5 + 2 / -1 + 3, or -3/2, which can also be - 1 1/2
Answer:
-3/2
Step-by-step explanation:
slope ('m') formula: (difference of the y-values) ÷ (difference of the x-values)
m = -2-(-5) ÷ -3-(-1)
m = 3 ÷ -2
slope = -3/2

Determine whether each equation represents a proportional relationship.
Y=2.5x
y= x - 4
Answer:
y=2.5x - Proportional
y= x - 4 - Not Proportional
Step-by-step explanation:
A linear function that is proportional is in the form y =kx (k is the constant of variation) and passes the origin.
The first equation given is in this form (2.5 is the constant) and it passes through the origin. It is proportional.
However, the second one is not proportional is it does not pass the orgin and it's not in y=kx form.

Answer:
1400
Step-by-step explanation:
two ways to do this
1, find the area of the shaded place.
2, find the area of the whole thing, subtract by the area of the corners.
this way is easier so its what ill do
whole box is 60*30=1800
3 corners are 10*10=100 15*10=150 and 15*10=150
1800-150-150-100 = 1400
or you could do it the first way
bigger box is 20*45=900
long box is 10*35=350
small box is 15*10=150
900+350+150=1400
