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??? :((
oksian1 [2.3K]

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.
