Answer:
45
Step-by-step explanation:
Since the values are relatively small substitute i = 1 to 5 into 3i and sum
(3 × 1) + (3 × 2) + (3 × 3) + (3 × 4) + (3 × 5)
= 3 + 6 + 9 + 12 + 15
= 45
Consider this solution:
if AB=AC, then
m(BCD)=180°-m(BCA).
In the triangle ABC m(BCA)=m(ABC)=(180-52)/2=64°.
Finally, m(BCD)=180-64=116°.
answer: D
Answer:
The number of centimeters will be greater than the number of inches.
Explanation:
The conversion between an inch (British Units) and centimeter (Metric Units) is
1 inch = 2.54 centimeters.
According to the conversion, every inch is equivalent to more than 2.5 centimeters.
If we take 6/15 and want to make 2/a equivalent to it, we first find out what was done to 6 (the numerator) to make it a 2. The 6 was divided by 3. So we do the same for 15.
15/3=5
The 3rd fraction is 2/5.
You use a similar method for the 4th fraction, b/120.
Now, we find out what was done to 15 (the denominator) to make it a 120.
The 15 was multiplied by 8. So we do the same for 6.
6*8=48
The 4th fraction is 48/120.
For the last fraction 16/c, we use 2/5 as one numerator (16) is a multiple of the other (2).
2 was multiplied by 8 to get to 16, so we do the same for 5.
5*8=40
The last fraction is 16/40.
