2) Acute triangles have 3 acute angles.
3) Right triangles have 3 right angles.
4) Obtuse triangles has 1 obtuse angle and 2 acute angles.

yo bro math sucks you feel me

Total would be $158.07

To calculate slaes tax and total cost, take the price (151.99) and multiply by tax rate, then add them together.

4%= .04

So Price (151.99) times tax(.04) would be 6.0796.

We're not finished, because that is just the tax.

Add them together, 151.99+6.0796 = 158.0696

Round to the nearest cent, so $158.07

Hope this helps and please consider marking branliest.

Answers:

The new volume is 1/8 of the old volume

The new surface area is 1/4 of the old surface area

======================================================

Explanation:

Volume:

Let's say the diameter is d = 60

That would make the radius r = d/2 = 60/2 = 30

The volume of the sphere is

V = (4/3)pi*r^3

V = (4/3)*pi*(30)^3

V = (4/3)*(30)^3*pi

V = 36000*pi

Now consider that d = 30 which is half of the original diameter.

So r = d/2 = 30/2 = 15

And also,

V = (4/3)pi*r^3

V = (4/3)*pi*(15)^3

V = (4/3)*(15)^3*pi

V = 4500*pi

The old volume was 36000pi and the new volume is 4500pi

Comparing the two volumes, we see that the reduction factor is

(new volume)/(old volume) = (4500pi)/(36000pi) = 1/8

The new volume is 1/8 of the old volume

smaller volume = (1/8)*(larger volume)

This is equivalent to saying the larger volume is 8 times that of the smaller volume.

------------------------------------------------------

Surface Area:

We'll use the same d and r values from earlier.

The diameter d = 60 leads to r = 30. We'll use this to find the surface area

SA = 4pi*r^2

SA = 4*pi*30^2

SA = 3600pi

For the smaller sphere (d = 30 and r = 15), we have

SA = 4pi*r^2

SA = 4*pi*15^2

SA = 900pi

The reduction factor is (900pi)/(3600pi) = 1/4

The smaller sphere has its surface area 1/4 that of the larger sphere.

smaller surface area= (1/4)*(larger surface area)

This is equivalent to saying the larger surface area is 4 times that of the smaller surface area.

Answer:

The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move. The point where the X and Y lines cross is marked “0” on the graph. It is called the “origin,” and is the starting point for plotting points.

Answer:

the anser is 5

Step-by-step explanation:

If x = 745/999, then

999x = 745

1000x - x = 745

This equation tells us that the fractional part of 1000x and x cancel upon subtracting. This means the block of repeating digits must be 3 digits long.

To verify this, suppose we write x = 0.yyy… , where y consists of 3 digits. Then

1000x = y.yyy…

1000x - x = y.yyy… - 0.yyy…

999x = y

x = y/999

which means y = 745.

Answer:

3 digits

Answer:

Step-by-step explanation:

This is segment addition in Geometry. Picture a straight line with endpoints A and C. B is a point stuck somewhere between them. The length of AC then is equal to the length of AB plus the length of BC. In algebraic terms:

AC = AB + BC. Filling in from the problem:

81 = 2x + 1 + 6x and combine like terms:

81 = 8x + 1 and subtract over the 1:

80 = 8x and divide by 8 to find

x = 10.

The appropriate and equivalent expression is listed below ;

(3 × 4) + (3 × 7)

Factorize :

Since 3 is common to both sides :

(3 × 4) + (3 × 7) = 3(4 + 7)

(5 × 9) - (5 × 6)

Factorize :

5 common to both sides :

(5 × 9) - (5 × 6) = 5(9 - 6)

(32 + 16) = 48

A common multiple of both 32 and 16 = 8

(8 × 4) = 32

(8 × 2) = 16

Answer:

-17

Step-by-step explanation:

First, let's see what the value of w is, by solving -5w - 5 = 5.

-5w - 5 = 5            Add 5 on both sides.

-5w = 10                Divide -5 on both sides.

w = -2

Now, we know that w is equal to -2, let's plug it in to find the value.

9(-2) + 1                 Distribute.

-18 + 1                    Add.
