$1 \frac{5}{6} +2 \frac{2}{11} =\frac{(1\times6)+5}{6} +\frac{(2\times 11)+2}{11} =\frac{11}{6}+\frac{24}{11} \\\\=\frac{11\times 11}{6\times 11} +\frac{24\times6}{11\times6} =\frac{121}{66} +\frac{144}{66}=\frac{121+144}{66} =\frac{265}{66}\\\\=\boxed{\bf{4\frac{1}{66}}}$

On tuesday shanice bought five hats. on wednesday half of all the hats that she had were destroyed. equation for... on thursday

wlad13 [49]

If X is the number of hats . . . reading backwards . . .

Thursday = Wednesday + Tuesday

17 = 1/2 X + 5

Solving:

17 - 5 = 1/2 X

12 = 1/2 X

24 = X

So she had 24 on Monday.

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.
