Answer:

BC = 21

Step-by-step explanation:

We know that AB + BC = AC

First we need to solve for x so using what we know lets set up the equation.

AB = 7x + 8

BC = 3x + 6

AC = 64

So (7x + 8) + (3x + 6) = 64

Combine like terms and solve.

10x + 14 = 64

10x = 50

x = 5

Now that we know that x = 5, to find the number for BC let's put that into the BC expression

3(5) + 6 = 21

There's your answer. BC = 21

Now if you really wanna make sure you can input the values we've found into the equation we first made.

AB + 21 = 64

7x + 8 + 21 = 64

7(5) + 8 +21 = 64

35 + 29 = 64

64 = 64

What is the median of the following set of numbers?<br><br> 15, 6, 7, 11, 2, 10, 15
Alenkasestr [34]

Answer:

First, you will need to arrange the data in an ascending order and the median is the middle value.

If the number of values is an even number, the median will be the average of the two middle numbers.

2, 6, 7, 10, 11, 15, 15

The median in this set is <em><u>10</u></em>.

Step-by-step explanation:

Answer:

167/346 or 0.483

Step-by-step explanation:

From the question given above, the following data were obtained:

Number of Tails (T) = 167

Number of Heads (H) = 179

Probability of tail, P(T) =?

Next, we shall determine total outcome. This can be obtained as follow:

Number of Tails (T) = 167

Number of Heads (H) = 179

Total outcome (S) =?

S = T + H

S = 167 + 179

Total outcome (S) = 346

Finally, we shall determine the probability of tails. This can be obtained as follow:

Number of Tails (T) = 167

Total outcome (S) = 346

Probability of tail, P(T) =?

P(T) = T / S

P(T) = 167 / 346

P(T) = 0.483

Thus, the probability of tails is 167/346 or 0.483

Find the diameter of a cone that has a volume of 104.67 cubic inches and a height of 4 inches. Use 3.14 for pi. 4 inches 6 inche
aleksandr82 [10.1K]
V:  volume of a cone = (πr²h)/3 = 104.67 in³
π:  pi = 3.14
r:  radius = 1/2 diameter = [unknown]
h:  height = 4 in

V = (πr²h)/3
V = r²(πh)/3

r² = (3V)/(πh)
r² = (3 ×104.67)/(3.14 × 4)
r² = 25

r = √25
r = 5  (but remember the radius is only 1/2 the diameter)

thus . . .
