Let L be the length of the deck = 42 feet

Let W be the width of the deck = 28 feet

 

A = LxW

A = 42 feet x 28 feet

A = 1176 square feet

 

Remaining area to be painted = 1176 square feet – 350 square feet

<span>Remaining area to be painted = 826 square feet</span>

I have to put 0.05 in a percentage then a fraction then put it in its lowest term
mart [117]
To convert a decimal to a percentage, multiply by 100 and add a percent sign.
0.05 • 100 = 5
0.05 as a percent is 5%.

To convert a decimal to a fraction, you find what place each value is in first.
The 5 in in the hundredths place, so the denominator would be 100 and the numerator would be 5.
0.05 as a fraction is 5/100.

To simplify a fraction, find the GCF (greatest common factor) of the numerator and denominator, then divide both sides by it.
5 is the largest factor of 5 and, since it goes into 200 as well, that makes it the GCF of 5 and 200.
Now divide 5 by 5 and 200 by 5.
5 / 5 = 1
200 / 5 = 40
5/100 in lowest terms, also known as simplest form, is 1/40.

Hope this helps! :)

What is a correct equation for the line passing through the point (-2,1) and having slope m=1/2
frez [133]

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

y-1=\dfrac{1}{2}(x-(-2))

y-1=\dfrac{1}{2}(x+2) - point-slope form

Covert to the slope-intercept form (y = mx + b):

y-1=\dfrac{1}{2}(x+2)          <em>use the distributive property</em>

y-1=\dfrac{1}{2}x+1          <em>add 1 to both sides</em>

y=\dfrac{1}{2}x+2   - slope-intercept form

Convert to the standard form (Ax + By = C):

y=\dfrac{1}{2}x+2     <em>multiply both sides by 2</em>

2y=x+4        <em>subtract x from both sides</em>

-x+2y=4         <em>change the signs</em>

x-2y=-4   -  standard form

Convert to the general form (Ax+By+C=0):

x-2y=-4        <em>add 4 to both sides</em>

x-2y+4=0   - general form
