A rectangle has length 3 feet and width 1/4 foot. What is the area of the rectangle?

1 answer:

5 0

$Area=width*length\\\\length=3ft\\width=\frac{1}{4}ft\\\\ Area=3*\frac{1}{4}=\frac{3}{4}ft^2\\\\Area\ of\ rectangle\ is\ equal\ to\ \frac{3}{4}ft^2.$

Solve for b, then solve for each angle in the triangle

lesya692 [45]

We know that the sum of the interior angles of a triangle equals 180, then,in this case we have the following equation:

$b+2b+(b+16)=180$

then, solving for b, we get:

$\begin{gathered} b+2b+(b+16)=180 \\ \Rightarrow4b+16=180 \\ \Rightarrow4b=180-16=164 \\ \Rightarrow b=\frac{164}{4}=41 \\ b=41 \end{gathered}$

now that we have that b = 41, we can find the measure of each angle:

$\begin{gathered} b=41 \\ 2b=2(41)=82 \\ b+16=41+16=57 \end{gathered}$

Which expression is EQUIVALENT to (m^8 n^-4) 1/4 ?

mamaluj [8]

Answer:

It's C because (m^8)^1/4 can simplify to (m^2)

and (n^-4)^1/4 can simplify to (n^-1), which would then become 1/n because it is a negative exponent.

Combine the two and you get: m^2/n

Write the point-slope form, then use that to write the slope-intercept form of the equation

Mashcka [7]

For a line with slope m that passes through a point $(x_1, y_1)$ , the point-slope form equation is the following.

$y-y_1=m(x-x_1)$

We have a given slope of 4 and a given point of (7,5). Now, plug in the values.

$\boxed{y-5=4(x-7)}$

That is the point-slope form of the line. Now, let's change this into slope-intercept form. Slope-intercept form looks like the following:

$y=mx+b$

Where m is the slope and b is the y-intercept. Let's do some algebra on our point-slop form equation to change it into slope-intercept form.

$y-5=4(x-7)$

This was our equation. Let's use the distributive property on 4(x-7).

$y-5=4x-28$

Now, add 5 to both sides of the equation

$\boxed{y=4x-23}$

This the slope-intercept form of the line. Thus, we have solved for both the point-slope form and the slope-intercept form. Hope this helps! :)
