Answer:
20 degrees
Step-by-step explanation:
A semicircle is half of a circle.
1/9 of a semicircle is 1/18 of a circle.
1/18 of 360 = 20 degrees.
The degree of 1/9 of a semicircle is 20°.
What is a semi-circle?A semicircle is half of a circle. It is a 2D shape formed when a circle is cut into two equal parts. We can create two semi-circles from any circle.
For the given situation,
The total angle of a circle is 360°
So, the total angle of the semicircle is 180°
Now, the degree 1/9 of a semicircle is given by
⇒ [tex](180)(\frac{1}{9} )[/tex]
⇒ [tex]20[/tex]
Hence we can conclude that the degree of 1/9 of a semicircle is 20°.

How can 1% of 300 be used to determine 64% of 300? Enter your answers in the boxes to correctly complete the statement. Please help me!
Answer:
64% of 300 is the same as 64 times the value of 1% of 300
Step-by-step explanation:
64% of 300 is the same as 64 times the value of 1% of 300 because 64/1 is 64.
Meaning:
0.64 * 300 = 64(0.01*300)
192 = 64(3)
192 = 192

Evaluate the discriminant of -3x2+5-4=0
Answer:
-23
Step-by-step explanation:
A quadratic equation is given to us and we are interested in finding the discriminant of the quadratic equation . As we know that ,
If the quadratic equation is in Standard form ,
[tex]\sf\longrightarrow ax^2+bx + c = 0 [/tex]
The discriminant is ,
[tex]\sf\longrightarrow D = b^2-4ac [/tex]
The given quadratic equation is ,
[tex]\sf\longrightarrow -3x^2 +5x - 4 = 0 [/tex]
On comparing it with the Standard form , we have ,
a = (-3)b = 5c = (-4)So that ,
[tex]\sf\longrightarrow D = (5)^2 - 4(-3)(-4)\\[/tex]

Answer and Explanation:
Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:
x = 4√(2)
y = 2(4) = 8
because where 4 = T,
x = T√2 and y = 2T
so again:

drag the ordered pair that are 5.5 units apart.
(-3, -3.5)
(5, 1.5)
(5, -3.5)
(-1.5, -3.5)
(-1.5, 2)
(-1.5, 2.5)
Answer:
(-1.5, -3.5) and (-1.5, 2)
Step-by-step explanation:
The x-coordinates in increasing order are ...
-3, -1.5, 5
The distances between pairs of these coordinates are ...
-1.5 -(-3) = 1.5
5 -(-3) = 8
5 -(-1.5) = 6.5
Clearly, any pair with x = 5 is too far away from any pair with a different x-value.
∆x = 1.5
If the distance between pairs is 5.5, then the distance formula tells us the y-coordinate differences for pairs with x-coordinates of -3 and -1.5 must be ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
5.5 = √(1.5^2 +(y2 -y1)^2) . . . substitute known values
30.25 = 2.25 +(y2 -y1)^2 . . . . square both sides
√28 = (y2 -y1) . . . . . . . . . . . . . . subtract 2.25 and take the square root
This value is irrational. Clearly none of the y-coordinates is irrational, so there are no point pairs with x-coordinates -3 and -1.5 that are 5.5 units apart.
__
∆x = 0
If the x-coordinates are the same, then the y-coordinates must differ by 5.5 in order for the points to be 5.5 units apart. The coordinates in order are ...
for x = -1.5, y = -3.5, 2, 2.5 . . . . . differences of 5.5, 6, 0.25
for x = 5, y = -3.5, 1.5 . . . . . . . difference of 5
The only pair we can find that is 5.5 units apart is ...
(-1.5, -3.5) and (-1.5, 2).
