Answer:
wouldn't they both be 88
I'm not sure if that's correct though
Answer:
x = 88
y = 88
Step-by-step explanation:
66 + 26 + x = 180 (collect like terms)
92 + x = 180 (subtract 92 on both sides)
x = 88
y = x
y = 88
They are vertical so their measures are the same.

Step-by-step explanation:
question 4.
x^2 - 8x - 20
(x -10)(x+2)
x² + 8x - 20 [-20 = -2 × 10]
x² - 2x + 10x - 20 [8 = -2 + 10]
x(x - 2) + 10(x - 2)

Ramiro se dedica a circular terrenos se le presenta un trabajo se circular un terreno cuadrado con una superficie de 470 metro cuadrados y le piden que lo circulen con 4 hilos de alambre de puas sobre postes. ¿cuantos metros lineales con alambre de puas nesecita?
Answer:
346.88 meters
Step-by-step explanation:
Given that the area of the square-shaped terrain is 470 square meters.
Let a be the side of the terrain, so
Area of the square-shaped terrain, [tex]a^2=470[/tex] square meters.
Therefore, the length of one side, [tex]a=\sqrt {470}=21.68[/tex] meters.
The length of single thread wire required in circulating the square-shaped terrain = the perimeter of the square-shaped terrain
As the perimeter of a square having side a = 4a
So, the length of single thread wire required in circulating the square-shaped terrain= 4 x 21.68 =86.72 meters
Therefore, the length of 4 thread wire required in circulating the square-shaped terrain= 4 x 86.72=346.88 meters.

2
D
d(t) = 400 • 3+
Answer:
D i believe.
Step-by-step explanation:
Hope this helps :)
The equation with the greatest growth factor is d(t) = 400 . 3^t
Correct option is D.
As per the given data:
Equations representing the number of bacteria in four different dishes as a function of time, t in days, are given.
To find out the equation with the greatest growth factor:
Growth Factor = Term whose power is raised to t.
For option (A), Growth Factor = (5/6) = 0.834
For option (B), Growth Factor = (1/50) = 0.02
For option (C), Growth Factor = (5/2) = 2.5
For option (D), Growth Factor = (3) = 3
Hence, the equation with the greatest growth factor is d(t) = 400 . 3^t

work out the area of this semi circle
Answer:
39.27
Step-by-step explanation:
The area of a semi-circle is pi times the radius squared divided by 2. So basically standard area of a circle formula (pi times the radius squared) but then you add in the extra step of dividing it by 2.
The formula looks like this:
π × r² ÷ 2
The radius is half the diameter of the circle. So basically think of it as a line to the middle of the circle. Our diameter is 10, (the diameter is the entire length of the circle. It gives us this already. If you need diameter and only have the radius add the radius together twice or multiply it by 2 to get the diameter. Fun fact..?)
and it tells us to substitute pi for 3.142.
So, plugging our numbers in we get:
3.142 x 5^2 ÷ 2 = 39.275.
Cut out the 3rd decimal place (5) as it tells us to only include the first 2 decimal places, and we finally end up with 39.27.
Hope this helps and have a nice day!

Step-by-step explanation:
through (2, -4) and parallel to y= 9/2x+3
Answer:
y=[tex]\frac{9}{2\\}[/tex] x-13
Step-by-step explanation:
first, since it's parallel the slope has to be the same and the y-intercept has to be different.
you will have y=9/2x+b
find b, by using the points you are given so you will get
-4=(9/2) times (2)+b.
then when sloving you will get b=-13 and so the full equation will be
y=9/2x-13

Write an explicit function to represent the following sequence.
3,9, 27, 81,...
Answer:
The equation would be if y is the numbers in the sequence (like 3, 9, 27) and x is the is the number in the order (like 3 is 1, 9 is 2, 81 is 4) the the equation would be y = 3^x.

in a bag there are 10 balls numbered 1 to 10 A ball is picked at random find the probability of picking the following
(a) number 7
(b) an odd number
(c) an even number
(d) an prime number
Answer:
a) 1/10
b) 1/2
c) 1/2
d) 2/5
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Total event/Total sample space
Since there are ten ball in the bag numbered 1 to 10
S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
n(S) = 10
Total sample space = 10
a) If we are to get the probability of picking the number 7.
(E) = {7}
n(E) = 1
Event = 1
Pr(picking 7) = 1/10
b) a) If we are to get the probability of picking an odd number
(E) = {1, 3, 5, 7 , 9}
n(E) = 5
Event = 5
Pr(an odd number) = 5/10 = 1/2
c) a) If we are to get the probability of picking an even number
(E) = {2, 4, 6, 8,10}
n(E) = 5
Event = 5
Pr(an even number) = 5/10 = 1/2
d) a) If we are to get the probability of picking prime
(E) = {2, 3, 5, 7}
n(E) = 4
Event = 4
Pr(prime) = 4/10 = 2/5
