If z is an even integer which of the following expressions must represent an odd integer?

1 answer:

8 0

There is no choice on your list that must represent an odd integer.

If 'z' is an even integer, then (z-1) and (z+1) must both be odd integers.

Answer:

1. 14%

2. 98%

3. 52%

4. 13%

5. 39%

6. 28%

7. 20%

8. 37%

9. 17%

10. 19%

Step-by-step explanation:

To get a percentage divide the small number by the big number and then multiply by 100.

1. 28/200 = 0.14 * 100 = 14

2. 931/950 = 0.98 * 100 = 98

3. 364/700 = 0.52 * 100 = 52

4. 13/100 = 0.13 * 100 = 13

5. 273/700 = 0.39 * 100 = 39

6. 161/575 = 0.28 *100 = 28

7. 200/1000 = 0.2 * 100 = 20

8. 68/400 = 0.37 * 100 = 37

9. 68/400 = 0.17 * 100 = 17

10. 95/500 = 0.19 * 100 = 19

Find the diamter of a circle if its area is 706.9mm²

Masteriza [31]

Answer:

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

r - radius

We have

$A=706.9\ mm^2$

Substitute:

$\pi r^2=706.9$ divide both sides by π

$r^2=\dfrac{706.9}{\pi}$ use π ≈ 3.14

$r^2\approx\dfrac{706.9}{3.14}\\\\r^2\approx225\to r=\sqrt{225}\\\\r= 15\ mm$

The diameter d = 2r.

Therefore

$d=2(15)=30\ mm$
