The equation that could be used to solve for the length of XY is XY = 22/sin(41)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Sine rule is used to show the relationship between the sides and angles of a trinagles.
Using sine rule on triangle XYZ:
XY / sin(Z) = XZ / sin(Y)
XY / sin(90) = 22/sin(41)
XY = 22/sin(41)
The equation that could be used to solve for the length of XY is XY = 22/sin(41)

Answer:
(5/7 - 1) * (2/3 + (1/6 - 1/9) * 18/5 + 1/15) - (2/7 + 1/3) * (-7/13)
= (5/7 - 7/7) * (2/3 + (3/18 - 2/18) * 18/5 + 1/15) - (6/21 + 7/21) * (-7/13)
= (-2/7) * (2/3 + 1/18 * 18/5 + 1/15) - 13/21 * (-7/13)
= (-2/7) * (2/3 + 1/5 + 1/15) + 7/21
= (-2/7) * (10/15 + 3/15 + 1/15) + 1/3
= (-2/7) * 14/15 + 1/3
= -4/15 + 1/3
= -4/15 + 5/15
= 1/15

Answer:
second option
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus
(x - 2.5)² + (y - (- 3.5))² = 6², that is
(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle
Answer:
You can not tell unless you have information about the relationship between the small and large boxes (for example, a large box is 2 times the weight of a small box) You can only tell that a small box and a large box's weight together is 34.5 kilograms.
Step-by-step explanation:
3L + 5S = 135
9L + 7S = 279
12L + 12S = 135 + 279
12(S+L) = 414
S+L = 34.5
