Step-by-step explanation:

m \angle DBE =  \frac{1}{2}  \{m (arc\: AC) + m (arc\: DE)  \} \\  \\  =  \frac{1}{2} (130 \degree + 40 \degree) \\  \\  =  \frac{1}{2}  \times 170 \degree \\  \\    \huge \purple{ \boxed{\therefore  m \angle DBE = 85\degree}}

Hence, option A 85° is the correct answer.

At a 3​-mile ​cross-country race, an athlete runs 2 miles at 6 mph and 1 mile at 12 mph. What is the​ athlete's average​ speed?
Tom [10]

Answer: the average speed is 7.5 mph or at least im pretty sure

Step-by-step explanation:

This is because if you make the 2 miles at 6 mph to 1 mile at 3 mph then you get 1 mile at 3mph and 1 mile at 12 mph. now that you have the unit rates of these you can add them. 1 + 1 = 2 miles and 3 + 12 = 15 mph now divide this by two and you get 7.5 mph per mile.

I hope this helped, if it did could you give me a good rating? lol

During the month of June, Ava kept track of the number of days she saw birds in her garden. She saw birds on 18 days of the mont
kirza4 [7]
There are 30 days in the month of June. Out of the 30 days, Ava saw birds on 18.

P(bird)=18/30

We can simplify the fraction by dividing both sides by 2.

P(bird)=18/30=9/15

9/15=0.6=60%

Theres a 9/15 or 60% chance that she will see a bird on July 1st.

List all x intercepts for y= -cos(1/2x + 1/5 pi) on the interval [-2/5pi,4pi]
Dahasolnce [82]
- cos ( 1/2 x + 1/5 π ) = 0 ( and because if cos α = 0, α= π/2 + k π, k ∈ Z )
1/2 x + π/5 = π/2 + k π,    k ∈ Z
1/2 x = π/2 - π/5 + k π  / * 2
x = π - 2π/5 + 2 k π
x = 3/5 π + 2 k π = 0.6 π + 2 k π
Answer:
If k = 0:  x 1 = 0.6 π = 3π/5
k = 1 : x 2 = 2.6 π = 13π/5
