Lane is 10 times Mel's age. If the difference in their age is 27, how old is Mel?

Answers

Answer 1

Answer: l - Lane's age
m- Mel's age.
Lane is 10 times Mel's age, so 10m = l
difference in their age is 27 so l - m = 27
Substitute l = 10m and you'll have:
10m - m = 27
9m = 27 /:9
m=3
And l = 10m = 10*3 = 30

So Lane has 3 years old and Mel has 30 years old.

Four of the angles of a pentagon measure 85°, 110°, 135°, and 95°. Find the measure of the missing angle. A. 115° B. 95°C. 135°D. 85°

Answers

Hence the missing angle is 115 degrees

Sum of angle in a pentagon

The sum of an interior angle of a pentagon is 540 degrees

Let the value of the fifth angle be "x", hence;

x + 85°+ 110° + 135° + 95° = 540

x = 540 - (85°+ 110° + 135° + 95°)

x = 540 - 425

x = 115 degrees

Hence the missing angle is 115 degrees

sum of all 5 angles of a pentagon = 540°
85 + 110 + 135 + 95 = 425
540 - 425 = 115
missing angle = 115° (answer is A)

On a particular day, the wind added 2 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 2 miles per hour from her rate on her return trip. Jaime found that in the same amount of time she could row 44 miles with the wind, she could go only 36 miles against the wind.What is her normal rowing speed with no wind?

Answers

44-2x=36+2x
x=2
Since x = 2, we need to divide 40 by 2 to get the true value in mph
Which is:
20 mph

Candice is traveling to Paris, where they measure distance in Kilometers and not miles . The taxi driver tells her that the distance from the airport to the hotel is 3,000 meters . How many kilometers is this ?

Answers

Therefore , the solution of the given problem of unitary comes out to be 3 kilometres from the airport to the motel.

What is an unitary method?

By combining the information obtained using this variable technique with all supplementary data from two individuals who used a specific tactic, the job can be completed. This mean that, if indeed the desired outcome materialises, either the stated person will be recognized or, in actuality, the colour by both huge processes will be skipped. For forty pens, a refundable charge of Rupees ($1.01) might be required.

Here,

Since there are 1,000 metres in a kilometre, we must split by 1,000 to convert metres to kilometres.

Thus, we can split by

=> 1,000 to convert 3,000 metres to kilometres:

=> 3 kilometres = 3,000 metres / 1,000.

Consequently, it is 3 kilometres from the airport to the motel.

If sin A = .5 and cos A = .866 then what is tan A to the nearest thousandth

Answers

Somewhere in a table of trig-function definitions that you have somewhere,
it mentions that

tan(a) = sin(a) / cos(a).

So it must follow that

tan(A) = (0.500) / (0.866) = 0.577 (rounded)
