What is the value of y ?

Mathematics
1 answer:
ArbitrLikvidat [17]3 years ago
6 0

Answer:

6

Step-by-step explanation:

Draw line segments ST and RQ. Triangle RUQ and SUT are similar, because they are in a circle. Now, you use similar triangles to get that QU/UT=RU/SU so 2 = 12/SU so SU = 6, or y = 6.


Note: This is generealized by the Power of a Point, which states that if you have two chords that intersect, then you can do the same thing and it will show that QU*SU=RU*TU. (You can change the variables but the similar triangles stay the same).

PLEASEEE HELP Me asap its really confusing
lawyer [7]

You can find the inverse of an equation by swapping the x and y, then solving for y.

f(x) = 4x - 12   f(x) is the equivalent of y in this case, so change it to a y

y = 4x - 12   Swap the x and y variables

x = 4y - 12

Solve for y

x = 4y - 12   Add 12 to both sides

x + 12 = 4y   Divide both sides by 4

\frac{x}{4} + 3 = y   Switch the sides to make it easier to read

y = \frac{x}{4} + 3   Change y back into f(x) to match what you were given

f(x) = \frac{x}{4} + 3

Jennifer got a box of chocolates. The box is a right triangular prism shaped box. It is 7 inches long, and the triangular base m
blsea [12.9K]
The first thing we should know is the area of the triangular base.
 Triangular base area: 
 A1 = root (s * (s-a) * (s-b) * (s-c))
 Where, s is the semi-meter of the triangle:
 s = (a + b + c) / 2
 a, b, c: sides of the triangle.
 Substituting:
 s = (2 + 3 + 4) /2=4.5
 A1 = root (4.5 * (4.5-2) * (4.5-3) * (4.5-4))
 A1 = 2.90
 Then, you must know the area of each rectangle associated with each side of the triangular base.
 Rectangle area 1:
 Ar1 = (a) * (l)
 Ar1 = (2) * (7)
 Ar1 = 14
 Rectangular area 2:
 Ar2 = (b) * (l)
 Ar2 = (3) * (7)
 Ar2 = 21
 Rectangular area 3:
 Ar3 = (a) * (l)
 Ar3 = (4) * (7)
 Ar3 = 28
 Finally the surface area is:
 A = Ar1 + Ar2 + Ar3 + 2 * A1
 A = (14) + (21) + (28) + 2 * (2.90)
 A = 68.8 in ^ 2
 answer:
<span> the surface area of the box of chocolates is 
</span> A = 68.8 in ^ 2

Law Incorporation [45]

1. 80 sheep when increase in the ratio 5:4 becomes 100 sheep.

2. The perimeter of the shape is : 26cm

<h3>What is Perimeter?</h3>

Perimeter is the outside boundary of a shape.

It is usually calculated by summing up all the length of the sides of that shape.

Analysis:

1. if the sheep is increased in the ratio 5:4

 then new number of sheep becomes 5/4 x 80 = 400/4 = 100 sheep

2. The perimeter of the shape is the sum of all the sides of the shape = 7 + 4 + 10 +5 = 26cm
