What is (2.3x10^-3)/(4.6x10^-7) written in scientific notation? Please show how you solved this.

1 answer:

5 0

(2.3*10^-3) / (4.6*10^-7)

(2.3*0.001) / (4.6*0.0000001) *10^-3=0.001 & 10^-7=0.0000001*

(0.0023) / (0.00000046) *2.3*0.001=0.0023 & 4.6*0.0000001=0.00000046*

5000 *0.0023/0.00000046*

So the answer is 5000

Answer:

arc PST = 254°

Step-by-step explanation:

arc QPT = 180° because it is a diameter

arc PQ = 74°

arc PT = 180° - 74° = 106°

arc PST = 360° - 106° = 254°

Answer:

B."5, -3, -4, 1, -1, 6, -4"

Step-by-step explanation:

We are given that

13,5,4,9,7,14,4

We have to find the deviation.

Mean= $\frac{sum\;of\;data}{total\;number\;of\;data}$

Using the formula

$Mean,\mu=\frac{13+5+4+9+7+14+4}{7}$

$Mean,\mu=\frac{56}{7}=8$

Deviation= $x_i-\mu$

$x_i-\mu$

13 5

5 -3

4 - 4

9 1

7 -1

14 6

4 - 4

Hence, option B is correct.

Answer:

$122.04
36.94%

Step-by-step explanation:

a) The amount of concern is ...

(total interest)/(number of payments) = interest/payment

$14,644.95/120 ≈ $122.04 . . . . amount of interest per payment

b) The ratio of concern is ...

(total interest)/(total payments) × 100% = 14,644.95/39,644.95 × 100%

≈ 36.94% . . . . percent of total payments that is interest

URGENT...Please help me with this question!!!!!!

Hunter-Best [27]

Answer:

option 2

Step-by-step explanation:

The problem can be solved using Pythagoras' identity for a right triangle.

The angle between due East and due North is 90°

The solution here involves using the Cosine rule.

let x be the direct distance between house and office, then

x² = 17² + 21² - 2(17)(21)cos90° → option 2

Note that since cos90° = 0 the equation reduces to

x² = 17² + 21² ← Pythagoras' identity
