Answer:
50 boys
Step-by-step explanation:
2/4 = 1/2
25*2=50
Answer:
Step-by-step explanation:
it is table 4, because it y has constant change for every input of x
which is 2
-4/-2=-8/-4=-16/-8=2
Let x represent the first number, y represent the second, and z represent the third.
x + y + z = 92
z = 3x
x = y - 7
Solve x = y - 7 for y.
x = y - 7
x + 7 = y
Fill in y and z so that we only have to worry about x for now.
x + y + z = 92
x + (x + 7) + (3x) = 92
x + x + 7 + 3x = 92
5x + 7 = 92
5x = 92 - 7
5x = 85
x = 85/5
x = 17
Solve for y.
y = x + 7
y = (17) + 7
y = 24
Solve for z.
z = 3x
z = 3(17)
z = 51
So x = 17, y = 24, and z = 51.
I think I would first convert it to hours to solve it and then back to minutes at the end. Super strange it’s been asked for in minutes.
So to convert 20 minutes into hours, you need to multiply by 3.
This means you need to do the same to the other side, cause if they’ve travelled 2.5 miles in 20 minutes, they’d travel 3 times that in an hour.
So this is 7.5m/ph
But then they want it in minutes, so I suppose 7.5/60?
So 0.125m/pm?
Step-by-step explanation:
<em>Given </em>
<em>circumference </em><em>=</em><em> </em><em>1</em><em>2</em><em> </em><em>inch</em>
<em>π</em><em> </em><em>=</em><em> </em><em>3</em><em>.</em><em>1</em><em>4</em>
<em>radius </em><em>(</em><em>r) </em><em> </em><em>=</em><em> </em><em>?</em>
<em>We </em><em>know </em>
<em>circumference </em><em>=</em><em> </em><em>2</em><em>π</em><em>r </em>
<em>1</em><em>2</em><em> </em><em> </em><em>=</em><em> </em><em>2</em><em>*</em><em> </em><em>3</em><em>.</em><em>1</em><em>4</em><em> </em><em>*</em><em> </em><em>r</em>
<em>r </em><em>=</em><em> </em><em>1</em><em>2</em><em> </em><em>/</em><em> </em><em>6</em><em>.</em><em>2</em><em>8</em>
<em>Therefore </em><em> </em><em>r </em><em>=</em><em> </em><em>1</em><em>.</em><em>9</em><em>1</em><em> </em><em>inch</em>
