Find the measure of line segment MK​

Mathematics

Answer:

  21

Step-by-step explanation:

When secants meet, the product of the length of the pieces from the meeting point to the two circle intersection points is the same for all.

  KL·KM = KJ·KC

Assuming the marks inside the circle apply only to the lengths inside the circle:

  8(8+x+5) = 7(7+2x+1)

  104 +8x = 56 +14x

  48 = 6x

  8 = x

Then the measure of MK is ...

  MK = x+13 = 8+13

  MK = 21

Evelyn is making a candy that contains 25% dark chocolate and the rest milk chocolate. The candy has 3 pounds of milk chocolate.
Setler [38]

Part A:

If 25% is dark chocolate and the rest is milk chocolate then, dark + milk = all

25% + milk chocolate= 100%

Subtract 25% from both sides and 100 minus 25 is 75 so, milk chocolate is 75% of all the chocolate.


Now, if there is 3 pounds of milk chocolate then 3 pounds= 75%.

You would divide by 3 so, 75 divided by 3 is 25.

1 pound or lb= 25% which us the amount of dark chocolate that there is.

Now, we know that there milk chocolate is 75% and dark chocolate is 25% of all the chocolate.

M= pounds of milk chocolate

D= dark chocolate

Equation: m divided by d or m/d= 75 divided by 25 or 75/25 or m/d=3 and m=3

3 divided by d or 3/d=3

3=3d

D=1


Part B:

There is 1 pound of dark chocolate in the candy.

Hope this helps! :)

Literally worth 100 POINTS answer the question!!!! WILL AWARD BRAINLIEST but only if work is shown and answer is actually CORREC
True [87]
The answer is 9/16 (decimal form:0.5625)

Since you have a multiply 2 and a divide 2, they cancel each other out (so you can remove both)
(1/2)^2 + 1/4 + (1/4)^2

Simplify both fractions with exponents
1/4 + 1/4 + 1/16

Add both 1/4
2/4= 1/2

1/2 + 1/16 = 9/16

Please give brainliest!!
