Machine can make 114 copies in 4 minutes and 45 seconds. So first convert 45 seconds into minutes. We will use ratio and proportion for that using 1 minute = 60 seconds. So let say X minutes = 45 seconds.
solve for X as shown
= X
0.75 = X
So 45 seconds =0.75 minutes
So it takes 4 minutes +0.75 minutes = 4.75 minutes for machine to make 114 copies. We have to find copies made in 1 minute. So lets say it makes C copies in 1 minute. Again we will use ratio and proportion
=
Now solve for C as shown
=
24 = C
So machine can make 24 copies in 1 minute. So thats the final answer.
Answer:
m∠1 is calculated as 49°.
Step-by-step explanation:
Consider the angles are the interior angles of a triangle.
m∠A =91°
m∠B = 40°
m∠1 = ?
We know that the sum of interior angles of a triangle is 180°. So,
m∠A + m∠B + m∠1 = 180°
or, m∠1 = 180°- m∠A - m∠B
or, m∠1 = 180°- 91° - 40°
or, m∠1 = 49°
Hence, m∠1 = 49°.
Hello! The answer to your question would be as followed:
Tom is incorrect
The odds of getting any number on a six sided die are 1:6
Every time he rolls, there is a 1:6 chance he would get any number.
Though, its possible to get the same number again. As the number tends toward infinity, the ratio of each number occurring to number of rolls can equal 1:6
Answer:
True
False
False
Step-by-step explanation:
Y - 4x = 8
y - 4x + 4x = 8 + 4x
y = 8 + 4x
y - 8 = 8 - 8 + 4x
<u>y - 8</u> = <u>4x</u>
4 4
1/4y - 2 = x
y - 4(1/4y - 2) = 8
y - y + 2 = 8
0y + 2 = 8
<u> -2 -2</u>
<u>0y</u> = <u>6</u>
0 0
y = 0
0 - 4x = 8
<u>+0 +0</u>
<u>-4x</u> = <u>8</u>
-4 -4
x = -2
(x, y) = (-2, 0)
