Answer:
12
Step-by-step explanation:
To determine the number of discs, divide the area of the metal sheet by the area of the discs
The metal sheets are in the shape of a rectangle, thus the area of a rectangle would be used to determine the area of the sheet
Area of a rectangle = length x breadth
56 x 33 = 1848 cm^2
The disc is in the shape of a circle.
area of a circle = πr²
π = 3.14
r = radius
3.14 x 7² = 153.86 cm²
Number of discs = 1848 /153.86 = 12
Answer:
Hi, I belive your answer is 188.02
sorry if it is wrong
Here is how to get the answer which is 188.02; 11.9 x 15.8= 188.02in²
and here you go have a splendid day!
Step-by-step explanation:
4(6)-6(3)+(8)
24-18+8
6+8
14
I agree with all your choices. First, you would convert all the equations to slope-intercept form.
Convert the initial equation 5x - 3y = 8 to get y = 5/3x + (-8/3)
We can't do anything with -5 = 3y = -8 because of the equal signs, therefore, option A is eliminated.
Option B in slope-intercept is y = 5x + -8, that is no where close to <span>y = 5/3x + (-8/3), so B is eliminated.
</span>
Option C in slope-intercept form is <span>y = 5/3x + (-8/3), the same as the initial equation, so choice C is correct.
</span>
Option D in slope-intercept form is y = 2.5/-1.5x + 4/-1.5, dividing the fraction results in y = -1.667x + -2.667, -1.667x is the equivalent of -5/3 and -2.667 is the equivalent of (-8/3). It does not matter if the slope is positive or negative, as long as they're the same. Choice D is correct.
Option E in slope-intercept form is y = -25/-15x + 8/-15, dividing -25/15x results in 1.667x, but 8/-15 is -0.534, -0.534 is not equal to -2.667. Choice E is eliminated.
Option F in slope-intercept form is y = -15/-9x + 24/-9, -15/-9 is 1.667 and 24/-9 is -2.667, this is equivalent to y = 5/3x + (-8/3). <span>Choice F is </span>correct<span>.
I agree with all your answers! :) </span>
