Probability of getting a pen in the first box:
7/12 = 0.58
0.58 x 100% = 58%
probability of getting a crayon in the second box:
5/10 = 1/2
half of 100 is 50, so 50%
or:
1/2 x 100% = 50%
Answer:
52
Step-by-step explanation:
m∠A + m∠B + m∠C = 180 | Sum of ∠s in △
28 + x-4 + 2x = 180 | Substitution
x = 52 | Algebra
Solve for x in the equation x^2 - 14x + 31 = 63?
<h3><u>Answer:</u></h3>
The value of x for given equation is x = 16 or x = -2
<h3><u>Solution:</u></h3>
Given that equation is
To find: value of "x"
<u>Subtract 63 from both sides we have:</u>
Now we will factor our given quadratic equation by splitting the middle term.
-14x can be splitted as -16x + 2x
<u>Take "x" as common from first two terms and "2" as common from last two terms</u>
<u>Take (x-16) common we have:</u>
Equating the terms to 0,
x - 16 = 0 or x + 2 = 0
x = 16 or x = -2
Therefore, the value of x are: 16 and -2
Both of these types of rocks would be susceptible to weathering and erosion.
Thus, the answer would be:
C. Both igneous rocks and metamorphic rocks.
Answer:Since the vehicles are travelling in the exact opposite direction, the sum of their rates is the rate at which they are separating. 48 + 64 = 112 miles per hour of separation.
728 miles ÷ 112 miles/hour = 6.5 hours
