A cell phone company has a basic monthly plan of $40 plus $0.45 for any minutes used over 700. Before receiving his statement, John saw he was charged a total of $48.10. Write and solve an equation to determine how many minutes he must have used during the month. Show your work and explain your answer

Answers

Answer 1

Answer:
Ok so we know he used over 700 because he was charged more than 40. Then we take the $8.10 and divide 0.45 into it. This then gives you 18 more minutes. Then add 18 to 700 and you get 718 min.

120% of 50 would be 60.

Find the values of x and y.

Answers

Refer to the notations above:

<BCD+40°=180° (angles on a strainght line)
<BCD=180°-40°
<BCD=140°

As BC=CD(given),△BCD is an isosceles triangle,thus <CBD=<CDB=x(properties of isosceles triangle).

We can then proceed to find x(<CDB and <CBD):

140°+ x + x=180°(angles sum of triangles)
2x=180°-140°
x=40°/2
x=20°

Then, we can again use the angles sum of triangle to solve y:

y+90°+20°=180°
y=180°-90°-20°
y=70°

Therefore, x=20° and y=70°.

Hope it helps!

Which is the best estimate for the weight of a stapler 4 ounces for pounds 4 inches or feet

Answers

The answer is 4 ounces. This problem just requires that you have a "feeling" of what the units are. You should know that 4 pounds is a heavy weight for a stapler: it would be difficult to handle. While inches and feet are not units of weight but of length.
