Answer:

18

Step-by-step explanation:

Divide the total weight of dough by the amount required for 1 pizza

20 \frac{1}{4} ÷ 1 \frac{1}{8} ( change mixed numbers to improper fractions )

= \frac{81}{4} ÷ \frac{9}{8}

• leave first fraction , change ÷ to × , turn second fraction ' upside down '

= \frac{81}{4} × \frac{8}{9} ( cancel 81 and 9 by 9 )

= \frac{9}{4} × 8 ( cancel 4 and 8 by 4 )

= 9 × 2

= 18 pizza's

Given: circle k(O), diameter US, measure of arc RU=50, measure of arc UT=30
sleet_krkn [62]

Answer:

angle RUS = 65 degrees

angle STU = 90 degrees

Step-by-step explanation:

(a) find angle RUS

Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees

Since US is the diameter,

angle URS is a right-angle.

Consider triangle RUS,

sum of angles of a triangle = 25+90+RUS = 180  

solve for

RUS = 180 - 25 - 90 = 65 degrees.

(b) Find STU

All diameters span a right angle at the circumference,

since we're given US is a diameter, this means that

angle STU is a right angle.
