Find the value of y.
y=
Answer:
0.5
Step-by-step explanation:
AB and AC are tangents from point A to the circle with center P at points B and C respectively.
Measures of the tangents drawn from external points to a circle are equal.
Therefore,
11y = 3y + 4
11y - 3y = 4
8y = 4
y = 4/8
y = 0.5

I really need help with this
Answer:
X would be 18x
Step-by-step explanation:
Work out a) 2/7+3/7 b) 5/8+7/8 c) 2/3-1/2
Answer:
a) 5/7 b) 12/8, 1 4/8
Step-by-step explanation:
Answer:
a) 5/7
b) 2/3
c) 1/6
Step-by-step explanation:
a) 2/7 + 3/7
since the denominators are both 7 we use 7 as the LCM ( lowest common multiple)
2+3/7 = 5/7
b) 5+7/8 = 12/8. 4 can go into both numbers so it gives 3/2
c) 2/3 - 1/2 multiply the denominator since they are different (3×2) =6
4-3/6 = 1/6

A water tank holds 1,216 gallons but is leaking at a rate of 5 gallons per week.
A second water tank holds 1,520 gallons but is leaking at a rate of 9 gallons per week.
After how many weeks will the amount of water in the two tanks be the same?
Answer:
im pretty sure it'd be 76 weeks!
Step-by-step explanation:
one water tank holds 1216 and loses 5 gallons/week
another water tank holds 1520 gallons and loses 9 gallons/week
youd make an equation:
1216-5x=1520-9x
(each side being the amount of water the tank can hold minus the amount it loses per week [x])
heres how you execute the equation:
1216-5x=1520-9x
-5x=1520-1216-9x
-5x=304-9x
-5x+9x=304
4x=304
x=304/4
76
after you do the equation, you get x=76, meaning 76 weeks! :-)
What conditions would be enough to prove that P is the circumcenter of HJK ?
Answer:
Option A and C
Step-by-step explanation:
Explanation for why I choose option A :-
If you look at the triangle, HK has a midpoint of point L, HJ has a midpoint of point M, and KJ has a midpoint of point N. Now if you stretch the lines inside of the triangle, they intersect at point P which is known as the circumcenter of HJK, true.
Explanation for why I choose option C :-
Now let us look at the lines stretch inside of the triangle. There are three lines which are congruent. Those lines are PK, HP, and PJ (they are the big lines inside the triangle) are congruent. Since those three line intersect at point P, it make the statement true that P is the circumcenter of HJK.
Why option B is not an answer?We do not know the third line (PN) measurements to find that if the three lines (PL, PM, and PN) are congruent and equal 90⁰. Since we do not know, it would not prove that they are congruent and P is the circumcenter of HJK.
Why option D is not an answer?Well it says that triangle HJK is an acute triangle which is true, but this doesn't prove that P is the circumcenter of HJK.
I hope this helps, thank you :) !!
The required conditions are L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex] and [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex]. So, options A and C are correct.
Given:
The given figure of a triangle HJK.
To find:
The conditions that would be enough to prove that P is the circumcenter of HJK.
Explanation:
The circumcenter of a triangle is the intersection of perpendicular bisectors and it is equidistant from each vertex of the triangle.
P is the circumcenter of triangle HJK if PL, PM, PN are perpendicular bisectors and P is equidistant from vertices H, J, K.
PL, PM, PN are perpendicular bisectors if L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex].
P is equidistant from vertices H, J, K if [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex].
The required conditions are L, M, N are the midpoints of [tex]\overline{HK}, \overline{HJ}, \overline{KJ}[/tex] and [tex]\overline{PK}\cong \overline{HP}\cong \overline{PJ}[/tex]. So, options A and C are correct, and other two options are incorrect.

The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?
Answer:
115.02 feet
Step-by-step explanation:
The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?
We solve this question using the Trigonometric function of tan
tan x = Opposite/Adjacent
x = Angle of depression = 72°
Opposite = Height of the tower = 354 feet
Adjacent = Distance of the airplane from the base of the tower = y
Hence,
tan 72 = 354/y
Cross Multiply
tan 72 × y = 354
y = 354/tan 72
y = 115.02157247 feet
Approximately = 115.02 feet
Therefore, the distance of the airplane from the base of the tower is 115.02 feet

How would you find the percent of discount if the sale price is $61.75 and the original price is $95
Answer:
Sale Price = $61.75 (answer). This means the cost of the item to you is $61.75. You will pay $61.75 for a item with original price of $95 when discounted 35%. In this example, if you buy an item at $95 with 35% discount, you will pay 95 - 33.25 = 61.75 dollars.

Answer:
Step-by-step explanation:
Hey There!
This is an example of a 45-45-90 special right triangle
We know this because one of the angles is 45 and the other is 90
to get the missing angle we subtract the given angles by 180
180-90-45=45 indicating that this is a 45-45-90 triangle
Given the hypotenuse we have to find the two legs
Remember the hypotenuse of a 45-45-90 triangle is [tex]x\sqrt{2}[/tex]
x being equal to one of the legs
so to get x we divide [tex]4\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]
[tex]\frac{4\sqrt{2} }{\sqrt{2} } =4[/tex]
so we can conclude that the two legs =4
