If AC = 52, AB = 8x + 8, and BC = 2x + 4, then the length BC is

Mathematics

Reil [10]2 years ago

Answer:

12

Step-by-step explanation:

AC = AB + BC

Since we know what each variable equals, we can write out the equation as shown:

52 = 8X + 8 + 2X + 4

Combining like terms:

52 = 10X + 12

Subtract 12 from both sides:

40 = 10X

Divide by 10:

X = 4

Now that we know X, we can figure out BC

BC = 2(4) + 4

BC = 8 + 4

BC = 12

Therefore BC is 12.

Find the value of x. (Type an integer or decimal.)
SOVA2 [1]

Answer:

70

Step-by-step explanation:

An angle formed by 2 tangent lines is equal to one half the measure of the major arc minus the measure of the minor arc.

we are given the minor arc ( 110 ) however we are not given the major arc.

Because circles make a 360 degree rotation we can find the major arc by subtracting the measure of the minor arc from 360

Thus, major arc = 360 - 110 = 250

Now that we have identified the major and minor arc we can find x

Recall that x = 1/2 ( major arc - minor arc )

Thus, x = 1/2 ( 250 - 110 )

250 - 110 = 140

140 / 2 = 70

Hence, x = 70

There is a bag full of red, yellow, and green marbles. There are 3 red, 2 yellow, and 7 green. What is the probability of gettin
statuscvo [17]

Answer:

1/6 and 16.67

Step-by-step explanation:

Add all the marbles, you get 12.

There's 2 out of 12 yellow marbles so you get 2/12

2/12 simplified to 1/6

So 1/6 is the probability as a fraction

Now to get the percentage just divide 100 by 6.

100/6 equals 16.67

Since it's 1/6 we multiply that by one

16.67 times 1 equals 16.67
