Answer:
The answer to your question is: D = non of the above
Step-by-step explanation:
Data
-4x - 4y = -5 (I)
x - 2y = 1 (II)
Process
Find the slopes of both lines
(I) -4x - 4y = -5
-4y = 4x + 5
y = 4/-4 x + 5/-4
y = - x + 5/4
(II) x - 2y = 1
- 2y = - x + 1
y = -1/-2 x + 1/-2
y = 1/2 x - 1/2
The slopes are different slope 1 = -1 and slope 2 = 1/2, so there is no relation between the lines.
Answer:
the simple interest is <em>36.</em>
Step-by-step explanation:
To find the answer we will first<em> divide 3 by 100</em> and we get <em>0.03.</em> Now <em>multiply 0.03 by $200</em>, which is<em> 6</em>. Then <em>multiply 6 by 6</em> <em>months</em> and we get 36. Therefore, <em>36 is our answer. </em>
Hi!
The correct answer is B, 1.997 • 10^2
This can be found by simply moving the decimal
place over x times (x represents the exponent). For example, if it were 1.12 • 10^2, you’d move your decimal place over 2 places to the right because it is positive (move left if negative).
Answer:
Step-by-step explanation:
Work is said to be done when a force applied to an object cause the body to move in a specified direction.
Work-done = Force * Distance
Since Force = mass * acceleration due to gravity
Work-done = mass * acceleration due to gravity * distance
Given mass = 1.4kg, distance = 0.7m and g = 9.8m/s²
Workdone in lifting the book off the floor = 1.4*0.7*9.8
Workdone = 9.604Joules
- Similarly, work done in lifting a 21-lb weight book 6 ft off the ground is expressed using the same formula as above;
Given mass = 21-lb, g = 32ft/s² and distance = 6ft
Workdone = 21 * 32 * 6
Workdone = 4,032 lb-ft²/s²
Hence, work-done in lifting a 21-lb weight book 6 ft off the ground is 4,032 lb-ft²/s²
Answer:
= 8.25
Step-by-step explanation:
6, 8, 8.5, 11
The middle number are 8 and 8.5
We then add them and divide by 2
= 8 + 8.5 / 2
= 16.5/2
= 8.25
