Since it takes 7 minutes to print 63 pages, and half an hour is 30 minutes, you create two ratios(unit per unit) and line up the units(minutes to minutes, pages to pages).

$\frac{7 min}{63 pages} = \frac{30 min}{Xpages}$

Now you cross multiply, 63 * 30 = 1890 and 7 * x = 7x.

So we have 1890 = 7x.

Then we divide both sides by seven.

$\frac{1890}{7} = \frac{7x}{7}$

270 = x, therefore you can print 270 pages in half an hour :)

What is the measurement of the vertex angle of an isosceles triangle if one of its base angles measures 42 degree

kari74 [83]

Hello from MrBillDoesMath!

Answer:

96 degrees

Discussion:

The base angles of an isosceles triangle are equal and a triangle has 180 degrees. In our case this means that

42 + 42 + (measure of vertex angle) = 180

84 + (measure of vertex angle) = 180 => (subtract 84 from both sides)

84 - 84 + (measure of vertex angle) = 180- 84 =>

(measure of vertex angle) = 180- 84 = 96

Thank you,

MrB
