Answer:

Step-by-step explanation:

1 minute = 8 revolutions

x minutes= 360 revolutions

Divide 360 by 8

The wheel will make 360 revolutions in 45 minutes

Check your work:

If 45 minutes = 360 revolutions, and the wheel revolves 8 times per 1 minute, 8 revolutions x 45 minutes should equal 360 revolutions.

Based off the table how long will it take to mow one lawn

weqwewe [10]

35 minutes for each lawn
Because 175 minus 5 equals 35
So the rule should be 35 minutes per lawn.
Now if you plug this rule into the next two numbers (245 and 7) and you divide them, you should get 35, and you do.

A paper clip is dropped from the top of a 144‐ft tower, with an initial velocity of 16 ft/sec. Its position function is s(t) = −

BabaBlast [244]

$\bf s(t)=-16t^2+144\implies \stackrel{velocity}{\cfrac{ds}{dt}}=-32t$

when does it hit the ground? check the picture below.

$\bf 0=-16t^2+144\implies 16t^2=144\implies t^2=\cfrac{144}{16}\implies t^2=9
\\\\\\
t=\sqrt{9}\implies t=3$

at that moment, the velocity is -32(3).

Vector a = 3i + mj, vector b = 2i - nj and vector c = ni + 8j. If a and b is perpendicular to each other and b and c are paralle

Tatiana [17]

May be you know it or not a two dimensional vector can be represented by a complex number.Why i have written this statement you will just know when you will see its solution

a = 3i + mj and b = 2i - nj are perpendicular to each other ,so their dot product

will be zero.

$i.e a.b = 0\\(3i + mj) .(2i - nj)=0\\6-mn=0\\mn=6$ j

vector b = 2i - nj and vector c = ni + 8j are parallel to each other. $2i - nj = k (ni + 8j)2/n = -n/8n^{2} =-16n=4i$ j

mn = 6

so m=6/4i

m=3/2i

m=3i^{4}/2i

m = 3i^{3}/2

m= -3i/2 as(i^{4} =1, i^{3} = -i[/tex][/tex]

Are these 3 equations equal 2.02, 0.02, 0.03 ? Show me 3 decimals that are equivalent

andriy [413]

No those decimals are not equal because if you put them into fractuons it would be this :

2 2/100
2/100
3/100
which do not equal the same thing

Equal decimals are

0.3
0.30
0.300

Because
0.3= 3/10
0.30= 30/100 = 3/10
0.300= 300/1000 = 3/10

They all end up being 3/10 in fraction form...
