Answer: 1/10

Step-by-step explanation:

From the question, we are informed that Karen spent 7/10 hour reading and 3/5 hours writing in her journal.

To calculate how much longer karen spent reading than writing in her journal, we have to subtract 3/5 from 7/10. This will be:

= 7/10 - 3/5

Note that the lowest common multiple of 5 and 10 is 10.

= 7/10 - 6/10

= 1/10

Therefore, the answer is 1/10

Iteru [2.4K]

Answer:

3.64 Km.

Step-by-step explanation:

Given,

Total population = 20,000 people

Population density = 480 people per square kilometer

Area of the circle town

A = \dfrac{20000}{480}

A = 41.667\ km^2

Radius of the circle town

\pi r^2 = 41.667

r = 3.64\ km

Hence, the radius of circle town is equal to 3.64 Km.

Find the measure of ∠P
Blizzard [7]
Triangles internal angles will always equal 180 degrees.

So, with that being said we can add up the known angles and subtract them from 180 to get our missing angle

28+67  = 95
180-95 = 85
so angle P is 85 degrees

– 36 – m = 8(4 + 2m)
valentina_108 [34]

Answer:

m = -4

Step-by-step explanation:

- 36 - m = 8(4+2m)

- 36 - m = 32+16m (to remove m from the left side, we need to add m to both sides)

- 36 = 32+17m (subtract 32 from both sides)

- 68 = 17m (divide by 17 on both sides)

-4 = m
