Answer:
a = -10
Step-by-step explanation:
33 - 4a = 73
To get <em>a</em> by itself, you must move 33 to the other side. To this, you must subtract it from both sides, canceling it out on the left side.
You will be left with: -4a = 73-33
Subtract 73 and 33, which will get you 40.
Now the equation is -4a = 40
To get <em>a </em>by itself, divide -4 into both sides. Doing this will isolate <em>a</em>.
The equation you will have after that is a = 40/-4.
Divide 40 by -4, which will get you -10.
Therefore, a = -10.
Answer:
32.9 inches
Step-by-step explanation:
this can be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base = 49
c = hypotenuse = diagonal = 59
l² + 49² = 59²
l² = 59² - 49²
3481 - 2401 = 1080
find the square root
32.9 in
Answer:
2
Step-by-step explanation:
<em>"How many ways can we choose a Senator from a chosen state?"</em>
Each state has 2 Senators. So there are 2 ways we can choose a Senator from any selected state.
<em>"How many ways can we choose 3 states to be represented?"</em>
The order in which the states are selected isn't important, so the number of ways 3 states can be selected is:
₅₀C₃ = 19,600
<em>"How many ways can the 3-Senator committee be formed such that no 2 Senators are from the same state?"</em>
The number of ways a committee can be formed is:
2×2×2×19,600 = 156,800
