Answer:

1

Step-by-step explanation:

my \: dear \:  \\ to \: find \: the \: slope \: of \: a \: line \: use \: the \: formular \\ slope =  \frac{y2 - y1}{x2 - x1}  \\ from \: the \: question \: x1 = 5 \:  \: y1 = 1\:  \: x2 =  - 5 \:  \: y2 =- 9 \\ slope =  \frac{ - 9 - 1}{ - 5 - 5}  =   \frac{ - 10}{ - 10}  = 1 \\ therefore \: slope = 1 \\ hope \: this \: helps \\ stay \: focused \: with \: your \: studies

What is the awnser to the equation r-4+6r=3+8r I'm trying to find what “r” is and if you can please solve the problem step by st
sattari [20]
Remember that you can do anything to an equation as long as you do it to both sides except divide by zero
so you can add like terms like this
you can add similar things like 1+3 and m+2m and m^2+2m^2 but not unlke things like 1+m or m+m^2

so m+2m=1m+2m=3m so

r-4+6r=3+8r
use commutative property to move numbers around (a+b=b+a)
group like terms
r+6r-4=3+8r
add like terms
1r+6r-4=3+8r
7r-4=3+8r
subtract 7r from both sides
7r-7r-4=3+8r-7r
0r-4=3+1r
-4=3+r
subtract 3 from both sides
-3-4=3-3+r
-7=0+r
-7=r

Finding Hypotenuse Lengths. Find the length of the hypotenuse.
ioda

Answer:

11) \frac{3\sqrt{5}}{2}

12) 4\sqrt{5}

13) 22

14) 18

15) 2

16) 24\sqrt{3}

Step-by-step explanation:

For these problems I used the pythagorean theorem: a^{2}+ b^{2}= c^{2} and SOHCAHTOA

Sin = \frac{opposite}{hypotenuse}

Cos = \frac{adjacent}{hypotenuse}

Tan = \frac{opposite}{hypotenuse}

11)

First find the length of the bottom side by using Cos

cos(60)=\frac{x}{3}

3(cos(60))=x

1.5=x

Then plug it into the formula for the pythagorean theorem to find the hypotenuse

3^{2}+ 1.5^{2}= c^{2}

9+2.25=c^{2}

\sqrt{11.25}=\sqrt{c^{2}}

\frac{3\sqrt{5}}{2}

12)

Find the length of the bottom side using Cos

cos(60)=\frac{x}{8}

8(cos(60))=x

4=x

Then plug it into the formula for the pythagorean theorem to find the hypotenuse

8^{2}+ 4^{2}= c^{2}

64+16=c^{2}

\sqrt{80} =\sqrt{c^{2} }

4\sqrt{5}

13)

Find the length of the other side by using Tan

tan(30)=\frac{x}{11\sqrt{3} }

11\sqrt{3}* (tan(30)=x

11=x

Then plug it into the formula for the pythagorean theorem to find the hypotenuse

(11\sqrt{3}) ^{2}+ 11^{2}= c^{2}

363+121=c^{2}

\sqrt{484} =\sqrt{c^{2}}

22

14)

(This is probably an easier way to do these problems)

Find the hypotenuse by using Cos (\frac{adjacent}{hypotenuse})

cos(60)=\frac{9}{x}

cos(60)x=9

x=\frac{9}{cos(60)}

x=18

15)

Find the hypotenuse using Sin (\frac{opposite}{hypotenuse})

sin(30)=\frac{1}{x}

sin(30)x=1\\x=\frac{1}{sin(x)}

x=2

16)

Find the hypotenuse using Cos (\frac{adjacent}{hypotenuse})

cos(60)=\frac{12\sqrt{3} }{x}

cos(60)x=12\sqrt{3}

x=\frac{12\sqrt{3} }{cos(60)}

x=24\sqrt{3}

74$ for working 6 hours.what is the hourly pay rate in hours per dollar
fgiga [73]

Answer:

.081 hours per dollar

$12.333 dollars per hour

Step-by-step explanation:

I'm a bit confused whether you just want hours per dollar or also dollars per hour, so I'll answer both.

First, for the dollars per hour, you want to do 74 divided by 6 equals 12 1/3. So each hour you get paid $12.333

Fort the hours per dollar, you do 6 divided by 74 equals .081.
