Answer:
2/7
Step-by-step explanation:
Since there are 18 males in the class
14 having A's and 4 not having A's
the probability would 4/14 which can be simplified to 2/7
I hope this helps^^
Answer:
they are like terms
Step-by-step explanation:
the sign ± is not a matter only veriable and power
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.
1) write a linear system - let a = boxes of apples and b = boxes of bananas
a + b = 86
32a + 16b = 1968
2) solve - use substitution
a = 86 - b
32(86 - b) + 16b = 1968
2752 - 32b + 16b = 1968
-16b = -784
16b = 784
b = 49
a + 49 = 86
a = 37
37 boxes of apples and 49 boxes of bananas
Answer:
630 feets
Step-by-step explanation:
From the triangle attached :
Using trigonometry, the height h, which is the height of climber to your eye level :
Tan θ = opposite / Adjacent
Tan 32 = h / 1000
h = tan 32 * 1000
h = 0.6248693 * 1000
h = 624.86935
Height from the ground :
624.86935 + 5.5
= 630.369 feets
= 630 feet
