Answer:
Step-by-step explanation:
1. the measure for HJ you can already see, start from h and draw a line to J. The measure shows 63 degrees.
2. start at F and draw a line to G first. the measure shows 65 degrees. Now continue the line from where you stopped at G, to H. There's no measure but you can see it is in a semicircle. A semicircle is 180 degrees andthe other two angles are 63 and 65.
So...
180=63+65+GH
subtract to get GH
180-63-65= 52
so the measure GH is 52 degrees. The full measure you are trying to find is FGH thought. So ad the 65 and the 52.
FGH =117 degrees.
3. The meaure is CDE. CD as you can see is a right angles, so 90 degrees. But there is no measure for DE. If you look to the angle vertical from DE which is BA. It measures 40 degrees. DE and BA are vertical so they are congruent. If DE equals 40 and CD equals 90, put them together and you get 130.
CDE= 130 degrees
4. Next measure is BCD. We already know CD is a 90 degree angle but BC is blank. You can see the measure BCD is in a semi circle. A semicircle equals 180, CD equals 90, and BA equals 40
so...
180= 90+40+BC
so subtract
180-90-40= 50
BC =50
so add BC=50 and CD=90. SO, BCD is 140 degrees.
5.The angle LMN is next. MN is 30 but LM is blank. LMN is in a semi circle.
A semicircle is 180 degrees.
so...
180=105+30+LM
subtract
180-105-30=45
LM = 45
Add LM=45 and MN=30
LMN is 75 degrees.
6.The last angle is LNP
If you look at it MP is a semi circle, so 180 degrees. And LM is 45 from our last question. so 180 +45=225
LNP=225
hope this helps
Answer:
The correct answer is:
Between 600 and 700 years (B)
Step-by-step explanation:
At a constant decay rate, the half-life of a radioactive substance is the time taken for the substance to decay to half of its original mass. The formula for radioactive exponential decay is given by:
First, let us calculate the decay constant (k)
Next, let us calculate the half-life as follows:
Therefore the half-life is between 600 and 700 years

Answer:
Mrs. Potts needs 72 feet of fencing.
Step-by-step explanation:
You find the perimeter of the rectangular garden, which is 24 yards. You then convert the yards to feet. There are 3 feet in a yard. You multiply 24 by 3 to get your final answer of 72 feet.
