30%. You want to add up all the muffins (which is 40) and make that your denominator. then as the numerator you make it as many blueberry muffins Anna has. (which is 12) you divide 12÷40×100. and that gives you a percent of 30.
(1/2) / 5 = 1/2 * 1/5 = 1/10 of a lb
90%, as each section is 10 percent!
Answer:
Step-by-step explanation:
<1=180°-74° so <1=126°
<2=180°-90° so <2=90°
<3=180°-116° so <3=64°
<4=180°-65° so <4=115°
by using 
° =(3)180°/5 -<1 -<2 -<3 -<4 =<5
you find out the last.
