Answer:

a = \frac{67}{110}

Step-by-step explanation:

Given

44a - 0.5 = 33 - 11a ( add 11a to both sides )

55a - 0.5 = 33 ( add 0.5 to both sides )

55a = 33.5 ( divide both sides by 55 )

a = \frac{33.5}{55} ← multiply numerator/ denominator by 2

a = \frac{67}{110} ← exact solution

Round 36.11 to the nearest tenth
Vilka [71]
To round to the nearest tenth - look at the number to the right of the tenth value ( the hundredth) and follow the rule
<em>5 or more round up, 4 or less round down
</em>As 1 is lower than 4, we round down.
36.11 therefore rounds down to 36.1

Crank

Answer:

X=65°

Step-by-step explanation:

Both angles combined is a right angle as indicated by the small square drawn on it, a right angle is always 90° therefore

Driving to your friend's house, you travel at an average rate of 35 miles per hour. On your
Mamont248 [21]

Answer:

14 miles.

Step-by-step explanation:

Let the distance traveled from home to destination = x miles.

Speed while going to friend's house = 35 miles per hour.

Speed while coming back = 40 miles per hour.

Total Time taken for the journey = 45 minutes = 0.75 hours.

Let the time taken while going to friend's house = y hours.

Therefore, the time taken while going to friend's house = (0.75 - y) hours.

To find x and y, model the speeds of both the journeys.

Speed while going to friend's house = Distance/Time.

35 = x/y.

x = 35y (Equation 1).

Speed while coming back = Distance/Time.

40 = x/(0.75 - y).

x = 40(0.75 - y) (Equation 2).

Since x = x, therefore:

35y = 30 - 40y.

75y = 30.

y = 30/75.

y = 0.4 hours.

Put y = 0.4 hours in Equation 1:

x = 35y.

x = 35(0.4).

x = 14.

Therefore, the distance between my friend's house and my house is 14 miles!!!

Answer:

150 ft^3

.1 ton or 200 lbs

Step-by-step explanation:

The volume is given by

V = l*w*h

V  = 5*5*6

V = 150 ft^3

To find how much 1 ft^3 weighed take the weight and divide by the volume

15 tons / 150 ft^3

.1 ton / 1 ft^3

1 ft^3  weights .1 ton

We know that 1 ton = 2000 pounds

.1 ton = 200 pounds
