7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21
10x-40=50
Add 40 to both sides
10x=90
X=9
4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20
The probability of rolling a 6 on the 1st roll is
, since there is only 1 out of 6 sides of the dice that has six pips.
The probability of rolling an odd number is
, since there are 3 out of 6 sides of the dice that has an odd number of pips.
Then the probablity of both events happening one after another is
. You have to multiply both probabilities of the events:
Answer: Yes
Step-by-step explanation: Let's first find the missing angle in the second triangle and to find this angle, remember that the sum of the measures of a triangle is 180 degrees so you should find that our missing angle is 67°.
Now, notice that we have two angles and the included side of one triangle
congruent to two angles and the included side of a second triangle.
Therefore, we can say the triangles are congruent by ASA.
Answer:
200 minutes
Step-by-step explanation:
Given that:
Cellular - Tastic (f) :
Monthly fee = $35
Per minute fee = $0.11
Dirt cheap call (g) :
Monthly fee = $55
Per minute fee = $0.01
How many minutes would you need to use for the cell phones to cost the same
amount?
Let number of minutes for cost to be equal = x
35 + 0.11x = 55 + 0.01x
Collect like terms
0.11x - 0.01x = 55 - 35
0.1x = 20
x = 20/0.1
x = 200
Hence, for cost to be the Same, 200 minutes must be used
1, 1/4, 1/16. The series expression is 64(1/4)^n
