Answer:

The sum would be

\frac{3}{2}

The difference would be

\frac{2}{3}  -  \frac{5}{6} =  -  \frac{1}{6}   \\  \\ or \\  \\  \frac{5}{6}  -  \frac{2}{3}  =  \frac{1}{6}

Determine the quotient: (22.8 × 10–3) ÷ (5.7 × 10–6)
lana66690 [7]

Answer:

0.399

Step-by-step explanation:

The key to doing this problem properly lies in knowing and following order of operations rules.

Here we must perform mult. and div.  before  addition and subtr., but even before that we must do all work enclosed in parentheses first.

(22.8 × 10–3) is evaluated by doing the mult. first, and then subtracting 3:

(228-3) = 225

and

(5.7 × 10–6) is evaluated by doing the mult. first, then subtracting 6:

(570-6) = 564.

Finally, we divide 225 by 564, obtaining 0.399 (after rounding off to three decimal places).

Pls can someone help me with math pls I’m this is my last points..
LiRa [457]

Answer:

Please read all of this! Underlined things are the answers. The area of the entire circle is 19.625

Step-by-step explanation:

(This is a circle so the middle line is the diameter. According to the attachment, the diameter is 5 cm. To find the area, we have to multiply π and the radius squared. The radius is half of the diameter.

5 ÷ 2 = 2.5

2.5² = 6.25

π = 3.14

3.14 x 6.25 = 19.625)

Ignore the top I just realized what I'm supposed to do but I left it there just in case you need help!

<u>The right and left shaded regions areas are 6.28 each.</u>

4 ÷ 2 = 2

2² = 4

3.14 x 4 = 12.56

Since this is a semi circle, we cut it in half.

12.56 ÷ 2 = 6.28

To find the top and bottom shaded region's areas, repeat the same steps.

3 ÷ 2 = 1.5

1.5² = 2.25

3.14 x 2.25 = 7.065

7.065 ÷ 2 = 3.5325

<u>The areas of the the top and bottom shaded regions are 3.5325 each.</u>
