Answer:

39˚

Step-by-step explanation:

The whole thing is a right angle, and we know that because of the square thing at the top.

These two angles are complementary, so we can subtract 51 from 90.

90-51=39˚

it takes Joey 1/16 of an hour to write one Thank you card how many cards can he write in 3/4 of an hour?

bearhunter [10]

To solve this problem you will need to use the cross product method:

1/16 of an hour → write 1 card

3/4 of an hour → write X cards

(3/4) ÷ (1/16) = X

0.75 ÷ 0.0625 = X

12 = X

Joey can write 12 Thank you cards in 3/4 of an hour.

There you go! I really hope this helped, if there's anything just let me know! :)

Answer:

33.275

Step-by-step explanation:

1 step: Difference in brackets

$3.5-2\dfrac{1}{3}=3\dfrac{1}{2}-2\dfrac{1}{3}=(3-2)+\left(\dfrac{1}{2}-\dfrac{1}{3}\right)=1+\dfrac{3-2}{3\cdot 2}=1+\dfrac{1}{6}=1\dfrac{1}{6}$

2 step: $0.75\div\dfrac{1}{3}$

$0.75\div\dfrac{1}{3}=\dfrac{75}{100}\div \dfrac{1}{3}=\dfrac{3}{4}\times \dfrac{3}{1}=\dfrac{9}{4}$

3 step: $1.28\div 0.04$

$1.28\div 0.04=128\div 4=32 \ \text{Move point two decimal places}$

4 step:

$2\dfrac{1}{4}\times 1\dfrac{1}{6}=\dfrac{2\cdot 4+1}{4}\times \dfrac{1\cdot 6+1}{6}=\dfrac{9}{4}\times \dfrac{7}{6}=\dfrac{63}{24}=\dfrac{21}{8}$

5 step:

$\dfrac{9}{4}+32-\dfrac{21}{8}+1.65=(32+1.65)+\left(\dfrac{9}{4}-\dfrac{21}{8}\right)=33.65+\dfrac{9\cdot 2-21}{8}=33.65-\dfrac{3}{8}=33.65-0.375=33.275$
