Calculate the following numbers into scientific notation (include units)

1 answer:

7 0

7800nm + 95pm = (7800x 10^-9) + (95x10^-12) = 7.800095x10^-6=7.800095mm

2500nm - 7pm = (2500x 10^-9) + (7x10^-12) = 2.50007x10^-6 = 2.50007mm

(65x10^4m) x (4.5x10^-6s-1) = clarify this question

(24x10^5m) / (2x10^-8s) = clarify this question

The area of a sector of an circle of a radius 5 cm, formed by an arc of length is 3.5cm. what is the answer

Natali5045456 [20]

Answer:

8.75cm²

Step-by-step explanation:

First we need to find the angle subtended by the arc

L = theta/360 * 2pir

3.5 = theta/360 * 2*3.14(5)

3.5 = theta/360 * 31.4

theta/360 = 3.5/31.4

theta/360 = 0.11146

theta = 0.11146 * 360

theta = 40.13 degrees

Area of the sector = theta/360 * pir^2

Area of the sector = 40.13/360 * 3.14*25

Area of the sector = 40.13/360 * 78.5

Area of the sector = 8.75cm

Hence the area of the sector is 8.75cm²

If the original quantity is 10 and the new quantity is 11, what is the percent crease?

LenKa [72]

Answer:

10 %

Step-by-step explanation:

We first find change in the quantities

Then we write the change in quantity on original quantity and multiply by 100%

This implies that,

$\frac{11 - 10}{10} \times 100\%$

$=\frac{1}{10}\times100\%$

$=10\%$

Therefore the percentage increase is 10%
