Find the slope of the given line on the graph. REMEMBER: Rise over run! <br> Pls show work!
Leviafan [203]

Answer:

the slope is -\frac{1}{3}

Step-by-step explanation:

Notice that you are given two points to use for the slope calculation:

(x_1,y_1)=(-4,4) \,\,and\,\, (x_2,y_2)=(5,1)

So we use the formula for the slope of a line given two points:

slope\,=\,\frac{y_2-y_1}{x_2-x_1} \\slope\,=\,\frac{1-4}{5-(-4)} \\slope\,=\,\frac{-3}{9} \\slope\,=\,-\frac{1}{3} \\

The radius of a semi-circle measures 5<br> units. Find its area.
shutvik [7]

Answer:

≈39.27 units

Step-by-step explanation:

To find the area of a semi circle, you use the formula for finding the area of a circle, which is \pir^{2}, and then you divide that by 2 since it is half of a circle.

In this case, \pi(5)^{2} ≈ 78.54

\frac{78.54}{2} = 39.27

Solve this equation.
spin [16.1K]

Answer:

D: 6 5/6

Step-by-step explanation:

Solve for a:

a + 7/6 = 8

Put each term in a + 7/6 over the common denominator 6: a + 7/6 = (6 a)/6 + 7/6:

(6 a)/6 + 7/6 = 8

(6 a)/6 + 7/6 = (6 a + 7)/6:

(6 a + 7)/6 = 8

Multiply both sides of (6 a + 7)/6 = 8 by 6:

(6 (6 a + 7))/6 = 6×8

(6 (6 a + 7))/6 = 6/6×(6 a + 7) = 6 a + 7:

6 a + 7 = 6×8

6×8 = 48:

6 a + 7 = 48

Subtract 7 from both sides:

6 a + (7 - 7) = 48 - 7

7 - 7 = 0:

6 a = 48 - 7

48 - 7 = 41:

6 a = 41

Divide both sides of 6 a = 41 by 6:

(6 a)/6 = 41/6

6/6 = 1:

Answer:  a = 41/6 or a= 6 5/6

Where I had $480 he used 2/3 of it to buy an electric van he also bought a tea set for $60 how
yawa3891 [41]

2/3 of 480 is 480 divided by 3 and that number times 2, which is 320. The man or woman probably used $60 of this to buy the tea set, which leaves them with $260.
