Answer: D
Step-by-step explanation:
If we substitute -12 into this equation we get:
Because -20 is in absolute value, we simply just use 20.
Thus,
262
Step-by-step explanation:
Step 1:
To find the nth term of a sequence the basic formula is
Sn = (n*d) + (a-d)
Whereas
Sn= nth Term
n= Term to be found
d= Difference between the terms in the sequence
a= First term in the sequence
Step 2:
Sn = (130*2) +(4-2)
= 260+2
Sn= 262
The nth term for the given problem is 262
Angle B measures 30 degrees.
Step-by-step explanation:
Step 1:
If two angles are complementary, the sum of the two angles will equal 90°.
So if angles A and B are complementary, the sum of the angles A and B will equal 90°.
It is given that cos A = 0.5, we can determine the value of A by taking the cos inverse of the value 0.5.
Step 2:
If cos A = 0.5, A = So angle A is 60°.
As A and B are complementary, angle A + angle B = 90°.
So 60° + angle B = 90°, angle B = 90° - 60° = 30°.
So angle B measures 30° while angle A measures 60°.
Find 9/20 of 100
9/20 * 100 = 900/20 = 45
So 45 people voted to change the law, and that's not enough.
1/4 = 2/8. Remember that. This means that 1/8 is equal to half of a month. It there is 5/8, you can add a half month for every eights. In this case, it will take 2 and a half months
Easy Way:<span>If your hair were to grow 1/4 inches a month, it would also grow 2/8 inches a month, since 1/4 = 2/8. How long with it take 1/8 (0.5/4)inches to grow? It would take a half of a month for your hair to grow 1/8 inches.
</span><span>Now that we know 1/8 inches grows in a half of a month, we add a half of a month for every eigths. Since we are trying to figure out how long it would take for it to grow 5/8 inches, we add 5 half months to get the answer of 2 and a half months. Kind of confusing, but that is the best way I can describe it.</span>
