Which is greater, 35% of 60 or 30% of 80?

Answers

35% of 60 = (35/100)*60 = 0.35 * 60 = 21

30% of 80 = (30/100)*80 = 0.30 * 80 = 24

24 is greater than 21.

30% of 80 is greater.

30%of 80=24
35%of 60=21 24is bigger so 30%of 80 is bigger

The length of a rectangle is 9 inches more than twice it’s width. If the perimeter of the rectangle is 48 inches find its length and width.

Answers

Answer:

$Length=19 inches\n\nWidth=5 inches$

Step-by-step explanation:

Let the width of the rectangle be 'w' inches

length of the rectangle= (2w+9) inches

Perimeter of the rectangle= 48 inches

Perimeter of a rectangle= 2(Length+Width)

$48=2((2w+9)+w)\n\n48=2(2w+9+w)\n\n48=2(3w+9)\n\n48/2=3w+9\n\n24=3w+9\n\n3w=24-9\n\n3w=15\n\nw=15/3\n\nw=5 inches$

$Width= 5 inches$

$Length=(2w+9)=2(5)+9=19 inches$

$Length=19 inches\n\nWidth=5 inches$

(a) What is the equation of the line, written in slope-intercept form? Show how you determined the equation.

Answers

First we need to find the slope. We can find the slope by $(rise)/(run)$ . The slope is $(-5)/(4)$ . You can also find the slope by calculating the change in the y values over the change in the x values. If the line looks like /, it has a positive slope, if it looks like \, it has a negative slope.

The slope intercept form is $y=mx+b$

Where $m$ is slope and $b$ is the y-intercept.

To find the y-intercept is (0,16.25) because we take the last $y$ value we know, 15, and add $\frac{5/4}$ (|m|). So now we just put it all into the equation.

$y=(-5)/(4)x+16.25$
