Answer:

The length of the base is $\frac{3}{4}$

Step-by-step explanation:

Since we know the formula to find the area of a triangle is $A = \frac{1}{2} bh$ , we can plug in and solve for b. When we plug into the formula we get:

$\frac{1}{2} (\frac{1}{5} )b$ = $\frac{3}{40}$

First multiply by 2 on both sides to get rid of the 1/2 on the left. After doing this we get:

$\frac{1}{5}b = \frac{3}{20}$

Then we can multiply by 5 on both sides to get rid of the 1/5 on the left. After doing this we get out answer:

$b = \frac{3}{4}$

Can someone help me please??? :((

Answer:

25 months

Step-by-step explanation:

when the rent, y = 0, we have,

y = -200.22x + 5014.20

y = 0

0 = -200.22x + 5014.20

200.22x = 5014.20

x = 5014.20 ÷ 200.22

x = 25.0434

x = 25(appx.)

Sorry, I don't know what you mean by interpolation and extrapolation:(

If each of the following represents the slope of a line (or line segment), give the slope a line that is perpendicular to it. (a

Crank

Answer:

$m_2 = -\frac{3}{4}$ -- (a)

$m_2 = -\frac{7}{3}$ -- (b)

$m_2 = -\frac{1}{4}$ --- (c)

$m_2 = -3$ -- (d)

Step-by-step explanation:

Given

$a.\ m = \frac{4}{3}$

$b.\ m = \frac{3}{7}$

$c.\ m = 4$

$d.\ m = \frac{1}{3}$

Required

Determine the slope of a perpendicular line

In geometry, the condition for perpendicularity is:

$m_2 = -\frac{1}{m}$

This formula will be applied in solving these questions.

$a.\ m = \frac{4}{3}$

$m_2 = -\frac{1}{m}$

Substitute 4/3 for m

$m_2 = -\frac{1}{4/3}$

Express as a proper division

$m_2 = -1/ \frac{4}{3}$

Convert to *

$m_2 = -1* \frac{3}{4}$

$m_2 = -\frac{3}{4}$

$b.\ m = \frac{3}{7}$

$m_2 = -\frac{1}{m}$

Substitute 3/7 for m

$m_2 = -\frac{1}{3/7}$

Express as a proper division

$m_2 = -1/ \frac{3}{7}$

Convert to *

$m_2 = -1* \frac{7}{3}$

$m_2 = -\frac{7}{3}$

$c.\ m = 4$

$m_2 = -\frac{1}{m}$

Substitute 4 for m

$m_2 = -\frac{1}{4}$

$d.\ m = \frac{1}{3}$

$m_2 = -\frac{1}{m}$

Substitute 1/3 for m

$m_2 = -\frac{1}{1/3}$

Express as a proper division

$m_2 = -1/ \frac{1}{3}$

Convert to *

$m_2 = -1* \frac{3}{1}$

$m_2 = -\frac{3}{1}$

$m_2 = -3$

What is the y-intercept of the line represented by y = 4x?

alexandr402 [8]

0, there is no y-intecept.
If there was a y-intercept it would look like y=4x+6, and 6 would be the y-intercept.
