Answer:
53°
Step-by-step explanation:
i will use ∩ to represent arc since there is no arc sign
if ∩EF = 34, then ∡EFC = 34
think of EFC as an angle in the larger circle
since EFC = 34, ABC = 34 because they are opposite angles and opposite angles are always congruent.
ABD = AB + BD = 19 + 34 = 53
Answer:
She has 5 candles left.
Step-by-step explanation:
Total of candy Sarah has = 25candies
If Sarah gave 2/5 of the candies to her sister, the total amount she gave her sister will be 2/5 of 25
2/5 of 25 = 10
The remaining candy left will be 25-10 which is 15.
If she gave 2/3 of the amount left to her friend, the amount she gave her friend will be 2/3×15 = 10candies.
Answer:
65
Step-by-step explanation:
If the intent of the question is to estimate, I would say do so through rounding. 12.95 is basically 13 and 5.2 is basically 5. So 13 x 5 = 65 would be a good estimate.
Answer: Length = 11 feet
Width = 6 feet
Step-by-step explanation:
A rectangle is a four sided shape that has 2 equal lengths,L and 2 equal widths,W
The perimeter of the rectangular piece of land is the total distance around it. It is expressed as
Perimeter = 2L + 2W = 2(L+W)
The perimeter is given as 34ft. It means that
34 = 2(L+W) - - - - - - - -1
The length of the rectangular piece of land is 5ft more than two times its width. It means that
L = W + 5
Substituting L = W + 5 into equation 1, it becomes
34 = 2(W + 5 +W) = 2(2W + 5)
2W + 5 = 34/2 = 17
2W = 17 - 5 = 12
W = 12/2 = 6 feet
L = W + 5 = 6+5
L = 11 feet
Sum is to add up all the numbers.
-5 + (-9) + 10
= -5 -9 + 10
= -14 + 10
= 10 - 14
= -4.
