Answer:
Step-by-step explanation:
m∠1 = 180-40= 140° (suplementary angles)
m∠2= 40° (vertical angles are ≅)
m∠3= 140° ( is ≅ to ∠1)
m∠4 = m∠6 = 40° ( same side corresponding ∠s, and vertical angles)
m∠5 = m∠7 = 140° ( same side corresponding ∠s, and vertical angles)
Answer:
m<1=140
m<2= 40
m<3= 140
m<4= 40
m<5=140
m<6= 40
m<7= 140
The formula for the kinetic energy is:
Ke = 0.5mv^2
Where ke is the kinetic enrgy
M is the mass
V is the velocity
Ke = 0.5mv^2
12.5 = 0.5(1) v^2
Solve for v
V = 5 m/s
Potential energy, pe = mgh
Where m is mass
G is accelearation due to gravity 9.8 m/s2
H is the height
98 = (1)(9.8) h
H = 10 m

The peregrine falcon flies in the time it takes the eagle to fly 40 miles is 64 miles away.
The average speed is the total distance traveled by the object in a particular time interval.
The average speed is a scalar quantity.
The average speed of a golden eagle is 30 mph and the average speed of a peregrine falcon is 48 mph.
The time to fly 40 miles (that time is x):
miles hours
30 ⇒ 1
40 ⇒ x
We use the ruleof three which is to multiply the cross quantities on the table and divide by the remaining quantity:
x = 40(1)/30
x = 4/3 hour
it takes the eagle 4/3 flies to fly 40 miles.
Now we use the velocity of the falcon: 48mph, which can also be represented as:
miles hours
48 ⇒ 1
and we need the distance in miles that the falcon flies in 4/3 hours :
miles hours
48 ⇒ 1
x ⇒ 4/3
Again we use the rule of three (multiply cross quantities and divide by the remainingquantity)
x = (48)× (4/3)
x = 64 miles
Hence, the peregrine falcon flies in the time it takes the eagle to fly 40 miles is 64 miles away.

sample of 10 apartments advertised in the localnewspaper is $580.
Assume that the standard deviation is$90. Find a 95% confidence
interval for the mean monthly rentfor unfurnished one bedroom
apartments available for rent in thiscommunity.
Answer:
Step-by-step explanation:
Confidence interval for population mean is given by :-
, where = Sample mean
z* = critical z-value.
= Population standard deviation.
n= Sample size.
Let x be the denotes the monthly rent for unfurnished one bedroom apartments available for rent in this community.
As per given , we have
n= 10
Critical value for 95% confidence : z* = 1.96
So the 95% confidence interval becomes,
Hence, a 95% confidence interval for the mean monthly rent for unfurnished one bedroom apartments available for rent in this community=
Answer: 0.7
Step-by-step explanation:
16.4 - 15= 1.4
1.4 ÷ 2= 0.7
