Answer:

x=62

Step-by-step explanation:

The interior angles of a triangle must add up to 180 degrees.

Therefore, the three angles inside of this triangle should equal 180 degrees when added together.

x+68.5+49.5=180

Combine like terms by adding 68.5 and 49.5

x+(68.5+49.5)=180

x+118=180

We want to find the value of x. Therefore, we must get x by itself.

We should perform the inverse operation to both sides. 118 is being added to x. The inverse of addition is subtraction. Subtract 118 from both sides.

x+118-118=180-118

x=180-118

x=62

x is 62 degrees.

Vedmedyk [2.9K]

Answer:

d = 1.67 miles

Step-by-step explanation:

Given that,

Speed of a person,  s=3\dfrac{1}{3}\ mph

We need to find how many miles can you walk in 30 minutes, given the  same pace.

30 minutes = 0.5 h

3\dfrac{1}{3}\ mph = \dfrac{10}{3}\ mph

Speed = distance/time

d=v\times t\\\\d=\dfrac{10}{3}\ mph\times 0.5\ h\\\\d=1.67\ miles

So, the person will cover a distance of 1.67 miles

just olya [345]
The total amount owed after 6 months will be found using the formula:
FV=P(1+r/100*n)^n
P=principle=$10000
r=rate=18%
n=terms=0.5


FV=10000(1+18/2*100)^0.5
FV=$10,440.30651
Thus the amount owed will be $10440.30651
