First you need yo figure out how much each gallon of paints costs. so divide 55 by 10.  55/10=5.5. So each gallon costs $5.50. After that you divide 30 by 5.5 to get the amount of paint you can buy for $30.00.   30/5.5=5.45454545..round that to get 5) so you can buy 5 gallons of paint for $30

Answer:

(–10, –2), (6, 6)

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

<u><em>Verify each case</em></u>

case 1) (5, –4), (–2, 1)

substitute in the formula

m=\frac{1-(-4)}{-2-5}

m=\frac{1+4}{-2-5}

m=\frac{5}{-7}

m=-\frac{5}{7}  ----> the slope is negative

case 2) (6, –10), (2, 10)

substitute in the formula

m=\frac{10-(-10)}{2-6}

m=\frac{10+10}{2-6}

m=\frac{20}{-4}

m=-5  ----> the slope is negative

case 3) (–10, –2), (6, 6)

substitute in the formula

m=\frac{6-(-2)}{6-(-10)}

m=\frac{6+2}{6+10}

m=\frac{8}{16}

m=0.5  ----> the slope is positive

case 4) (5, –1), (–6, 6)

substitute in the formula

m=\frac{6-(-1)}{-6-5}

m=\frac{6+1}{-6-5}

m=\frac{7}{-11}

m=-\frac{7}{11}   ----> the slope is negative

Answer:

Angle A = 53

Step-by-step explanation:

All triangles add up to 180 so...

Lets use x to describe angle A

100+27+x=180

127+x=180

x=53

I'm confused what its asking about b and c but hope this helps a bit :)

Directions: Find the indicated trigonometric ratio as a fraction in simplest form. 1. Sin L =
Rainbow [258]

Answer:

\sin L = 0.60

tan\ N = 1.33

\cos L = 0.80

\sin N = 0.80

Step-by-step explanation:

Given

See attachment

From the attachment, we have:

MN = 6

LN = 10

First, we need to calculate length LM,

Using Pythagoras theorem:

LN^2 = MN^2 + LM^2

10^2 = 6^2 + LM^2

100 = 36 + LM^2

Collect Like Terms

LM^2 = 100 - 36

LM^2 = 64

LM = 8

Solving (a): \sin L

\sin L = \frac{Opposite}{Hypotenuse}

\sin L = \frac{MN}{LN}

Substitute values for MN and LN

\sin L = \frac{6}{10}

\sin L = 0.60

Solving (b): tan\ N

tan\ N = \frac{Opposite}{Adjacent}

tan\ N = \frac{LM}{MN}

Substitute values for LM and MN

tan\ N = \frac{8}{6}

tan\ N = 1.33

Solving (c): \cos L

\cos L = \frac{Adjacent}{Hypotenuse}

\cos L = \frac{LM}{LN}

Substitute values for LN and LM

\cos L = \frac{8}{10}

\cos L = 0.80

Solving (d): \sin N

\sin N = \frac{Opposite}{Hypotenuse}

\sin N = \frac{LM}{LN}

Substitute values for LM and LN

\sin N = \frac{8}{10}

\sin N = 0.80
