Answer:
inverse
y = 10/x
Step-by-step explanation:
Inverse variation is described by an equation of the form ...
y = k/x
The value of k is a constant equal to ...
k = xy = 5·2 = 10·1 = 15·2/3 = 20·1/2 = 10
__
Here, the products of the x- and y-values are all 10, so the inverse variation equation is ...
y = 10/x
A box contains 14 large marbles and 11 small marbles. Each marble is either green or white. 7 of the large marbles are green, and 6 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is large or white?
Answer:
21/22
Step-by-step explanation:
Well, 14+11 is 25. 7/14 are green, 6/11 are white. Ok, so 7/14 large marbles are green, and 5/11 small marbles are white. So now we add.
7/14+5/11
1/2+5/11
11/22+10/22
21/22

Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
5)
Adj = 14
Hyp = 26
∠X
so use
CAH
Cos(X) = 14/26
X = arcCos(14/26)
X = 57.421°
X = 57.4 ° ( rounded to nearest 10th )
6)
∠X
Hyp = 46
Opp = 12
use SOH
Sin(x) = 12/46
X = arcSin(12/46)
X = 15.121°
X = 15.1 ° ( rounded to nearest 10th )
7)
∠X
Adj = 29
Opp = 24
use TOA
Tan(x) = 29 / 24
X = arcTan( 29 /24)
X = 50.389
X = 50.4 ° ( rounded to nearest 10th )
8)
∠X
Adj = 22
Opp = 6
use TOA agian
Tan(x) = 6 / 22
X = arcTan(6/22)
X = 5.194
X = 5.2 ° ( rounded to the nearest 10th )

The perimeter of a square is 20. What is the length of one of the diagonals of the square? Show work or explain how you obtained your answer
Answer:
The perimeter of a square is 20
if length of the square is x
perimeter of a square = x + x+ x + x = 4x = 20
4x = 20
x= 20/4
x = 5
Let get the length of one of the diagonal is y
According to the Pythagoras low,
y^2 = x^2 + x^2
y^2 = 5^2 + 5^2
y^2 = 25 + 25
y^2 = 50
y= sqrt(50)

1) Find the missing angle.
31°
949
? + 31° + 94° = 180°
? + 125° = 180°
? = 180° - 125°
? = 55°
Answer: 52°
Step-by-step explanation:
Angles in a triangle always add up to 180°.
So to work out what the missing angle is, you would have to add 34 and 94 together.
34+94=128
Then you would have to take 128 away from 180.
180-128=52°
Hope this helps :)

Hana is putting in a tile floor she needs to determine the angles that should be cut in the tires to fit in the corner that angle in the corner measures 90° one piece of the tire will have a measure of 38 degrees write an equation and use it to determine the measure of the unknown angle
Answer:
x = 52°
Step-by-step explanation:
I have attached an image to depict the given angles.
From the attached image, we can see that the unknown angle is x°.
Thus, since that corner is 90°, then;
x + 38 = 90
Subtract 38 from both sides to get;
x = 90 - 38
x = 52°

Meghan flipped a quarter and rolled a standard six-sided die.
The probability that the coin landed on heads and the die landed on an even number is __%.
Answer:
25%
Step-by-step explanation:
right on the test
The required probability of the coin landed on heads and the die landed on an even number is 25%.
Given,
Meghan flipped a quarter and rolled a standard six-sided die. The probability that the coin landed on heads and the die landed on an even number is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Sample space of coin = { head, tail } = 2
Sample space for die = { 1, 2, 3, 4, 5, 6 } = 6
favorable outcome for coin = head = 1
favorable outcome for the die to landed on even number = {2, 4, 6} = 3
Now the probability that the coin landed on heads and the die landed on an even number is,
P = probability of head-on coin * probability of the even number on die
P = 1/2*3/6
P = 1/4
P = 0.25 and 25%
Thus, the required probability of the coin landed on heads and the die landed on an even number is 25%.
