Answer:
The volume of paint that covers the whole car is 
gallons or one and a quarter gallons.
Step-by-step explanation:
Let the volume of paint required to cover whole car be 'x'.
Given:
Volume of paint to cover one-fifth of a car = one-fourth of a gallon.
We use unitary method to determine the volume of paint required.
∵ One-fifth of a car requires paint = 
∴ Whole volume of car requires paint = 
Therefore, the volume of paint that covers the whole car is gallons or one and a quarter gallons.
Answer:
70 shirts
Step-by-step explanation:
First off, there are 5 shirts. 2 shirts take 28 seconds. If you divide 28 by 2, that means that each shirt takes 14 seconds.
5x14=70
Therefore, it takes 70 seconds to fold 5 shirts.
Answer:
0.965925826 = 0.97
Step-by-step explanation:
just put in the calculator >>> cos(15)
Answer:
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
<span>y=−3x+2</span> is a linear equation in slope-intercept form with
slope <span>m=<span>(−3)</span></span>
(and y-intercept <span>=2</span>)
We want the equation of a line with slope <span>m=<span>(−3)</span></span> through the point <span>(<span>−2</span>,<span>−8</span>)</span>
Using the point-slope linear equation form:
<span><span>(y−<span>(−8)</span>)</span>=<span>(−3)</span><span>(x−<span>(−2)</span>)</span></span>
Simplifying
<span>y+8=−3x−6</span>
or, in standard form
<span>3x+y=−<span>14</span></span>
