Answer: 1072.8 cm³

Step-by-step explanation:

The volume of a hemisphere: 2/3πr³

Radius = 8 cm

2/3 × 22/7 × 8³

2/3 × 22/7 × 512 = 1072.761

1072.761 ≈ 1072.8

The volume of this hemisphere is 1072.8 cm³

Hope this helped!

Line m passes through the points (-4, 3) and (-4, 7). What is the slope of the line that is parallel to line m? Show all of your

Diano4ka-milaya [45]

Answer:

The slope of this line would be undefined.

Step-by-step explanation:

In order to find the slope of a parallel line, we first need to find the slope of the original line. We can do this by using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (7 - 3)/(-4 - -4)

m = (7 - 3)/(-4 + 4)

m = 4/0

Since we cannot divide by 0, we know the slope to be undefined. Also, since parallel lines have the same slope, we know the second line to also have an undefined slope.

Asa saves dimes and quarters so that he will have exact change for he bus. He dabs and then dumps the container that he has been

koban [17]

Asa has 15 dimes and 32 quarters.

Step-by-step explanation:

Given,

Total coins = 47

Worth of coins = $9.50 = 9.50*100 = 950 cents

1 dime = 10 cents

1 quarter = 25 cents

Let,

Number of dimes = x

Number of quarters = y

According to given statement;

x+y=47 Eqn 1

10x+25y=950 Eqn 2

Multiplying Eqn 1 by 10

$10(x+y=47)\\10x+10y=470\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(10x+25y)-(10x+10y)=950-470\\10x+25y-10x-10y=480\\15y=480$

Dividing both sides by 15

$\frac{15y}{15}=\frac{480}{15}\\y=32$

Putting y=32 in Eqn 1

$x+32=47\\x=47-32\\x=15$

Asa has 15 dimes and 32 quarters.
