Answer:
∠DEF =56°
Step-by-step explanation:
We are given that arc DEF = 248°
So, arc DCF = 360°-248°
arc DCF = 112°
Now we are required to find the ∠DEF.
So, we will use Inscribed angle theorem.
Inscribed angle theorem: The measure of an inscribed angle is equal to one-half the measure of its intercepted arc.
Intercepted arc = arc DCF = 112°
Inscribed angle = ∠DEF
⇒∠DEF = 
⇒∠DEF = 
⇒∠DEF =56°
Hence the measure of ∠DEF =56°
Answer:
3000
Step-by-step explanation:
Answer: A. $0.60
Step-by-step explanation:
The prices for which the carpets were sold are
1) 100 square feet for $67
2) 200 square feet for $130
3) 400 square feet for $240
4) 800 square feet for $504. We would determine the unit cost per square foot for each of them. It becomes
1) 1 square feet costs 67/100 = $0.67
2) 1 square feet costs 130/200 = $0.65
3) 1 square feet costs 240/400 = $0.6
4) 1 square feet costs 504/800 = $0.63
The unit cost per square foot of carpet for the worst deal is $0.6
Answer:
At a glass vase factory, 3 out of the last 15 vases produced were chipped.
We can find the probability by using
P(E)= Total number of outcome in E/ Total number of outcome in the sample space.
The event of getting 3 vases is E = 3 vase
The sample space is given by S = {1,2,3,4…….,13,14,15}
The no. of possible outcome in the Event E is 3 vases and the no. of possible outcome in Space S is 15.
Probability of getting 3 vase is
P(3) =3/15 which is 1/5.
