A street in San Francisco rises 20 feet for every 100 feet horizontally. What is the measure of the angle of elevation,
x, to the nearest degree?

Answer:

r = 12.89

Step-by-step explanation:

18(2) + 15(3) = 81 = C

C = 2πr

81 = 2πr

81/2 = πr

r = 81/2π ≈ 12.89

Answer:

y = [tex]\frac{4}{5}x+\frac{54}{5}[/tex]

Step-by-step explanation:

Equation of a line has been given as,

[tex]y=\frac{4}{5}x+\frac{3}{5}[/tex]

Here, slope of the line = [tex]\frac{4}{5}[/tex]

y-intercept = [tex]\frac{3}{5}[/tex]

"If the two lines are parallel, there slopes will be equal"

By this property slope of the parallel line to the given line will be equal.

Therefore, slope 'm' = [tex]\frac{4}{5}[/tex]

Since, slope intercept form of a line is,

y = mx + b

Therefore, equation of the parallel line will be,

y = [tex]\frac{4}{5}x+b[/tex]

Since, this line passes through a point (-6, 6),

6 = [tex]\frac{4}{5}(-6)+b[/tex]

6 = [tex]-\frac{24}{5}+b[/tex]

b = [tex]6+\frac{24}{5}[/tex]

b = [tex]\frac{30+24}{5}[/tex]

b = [tex]\frac{54}{5}[/tex]

Equation of the parallel line will be,

y = [tex]\frac{4}{5}x+\frac{54}{5}[/tex]

Answer:

try setting them equal to each other

The explicit formula for a arithmetic sequence is a_n = a_1 + (n - 1)d.

We want to find a_21.

a_21 = 17 + (21 - 1)(10)

a_21 = 17 + (20)(10)

a_21 = 17 + 200

a_21 = 217

The 21st term is 217.

Answer:

mixed number form 1 1/9

decimal form 1.11111111111111 it goes on forever

percent form 111.111111111111% it goes on forever (again)

Step-by-step explanation:

i hope that helps!

Answer:

1  1/9

Step-by-step explanation:

10/9, you get 1 as the whole number.

You have a 1 left over when dividing 10 and 9. the 1 will be over 9.

Giving you 1 as the whole number and 1/9 next to it.

Answer:

about 10 without a remainder of 4

Step-by-step explanation:

So, add up the number and divide by how many number you have (definition of mean). 8 + 25 + 9 + 10 + 11 + 1 all divide by 6 (since there are 6 numbers)

8 + 25 + 9 + 10 + 11 + 1 is 64.

64/6 is about 10 without a remainder of 4

Answer:

12 divided by 1 can be 12. If thats what you mean and if not, just tell me by explaining with more detail

Step-by-step explanation:

Answer:

Does fill in!!!!

Step-by-step explanation:

1st substitute x with -4

5+3(-4)=-7

2nd step multiply

5-12=-7

3rd step subtract

-7=-7

so yes -4 is correct!!!!

Answer:

-4 is a solution

Step-by-step explanation:

x = -4

Equation:

5 + 3x = -7

Substitute x for -4

New equation:

5 + 3 x -4 = -7

Solve:

3 x -4 = -12

5 + -12 = -7

-7 = -7

Answer:

I got you, give me a few minutes

1st one: 6x+12+6y

2nd one: -12a-20b

4th one: 2x times 18

Step-by-step explanation:

1: -4x + 2y + 10

2: -12a^2 + 20ab

3: i didnt know it sorry

4: x^2 - 9x + 18

all you need to do is the order of operations

Answer: English please

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points and simplify:

(y2 - y1) / (x2 - x1)

(70 - 56) / (5 - 4)

14 / 1

= 14

So, the slope of the line is 14.

Answer:

m=14

Answer:

4x^2 + 19x - 63

Step-by-step explanation:

3(x-3) = 3x - 9

x + 3x - 9 (x + 7)

(4x -9)(x + 7) = 4x(x) + 4x(7) - 9x - 9(7)

4x^2 + 19x - 63

Answer:

you have #5 correct and that is how I would do it.

you could also figure out the number of flowers and put 6 in each vase.

7x12= 84

84/6= 14.

I still think your way is best.

Answer:

True because when you multiply the 2 by everything in the parentheses you get 4x + 6y which is 4x + 6y = 4x + 6y. and when you solve it you'll get 0 = 0

Step-by-step explanation:

Answer:

2×2x +2×3y=

4x+6y

Step-by-step explanation:

you first clear the bracket as i have shown above

you use the one outside the bracket to multiply the ones inside the bracket and when you multiply you get 4x+6y

Answer:

B)[tex]y=\frac{-2}{3}x-\frac{-13}{3}[/tex]

Step-by-step explanation:

2x +3y = 5

    3y = -2x + 5

Divide both sides by 3

[tex]\frac{3y}{3}=\frac{-2x}{3}+\frac{5}{3}\\\\y =\frac{-2}{3}x+\frac{5}{3}[/tex]

Parallel lines have same slope.

m = (-2/3) ; (-2 , -3)

y - y1 = m(x -x1)

[tex]y-[-3]=\frac{-2}{3}(x-[-2])\\\\y + 3 = \frac{-2}{3}(x +2)\\\\y + 3 =\frac{-2}{3}x + 2*\frac{-2}{3}\\\\y+3=\frac{-2}{3}x-\frac{4}{3}\\\\y=\frac{-2}{3}x-\frac{4}{3}-3\\\\y=\frac{-2}{3}x-\frac{4}{3}-\frac{3*3}{1*3}\\\\y=\frac{-2}{3}x-\frac{4}{3}-\frac{9}{3}\\\\y=\frac{-2}{3}x-\frac{-13}{3}[/tex]
