Does anyone know 8-10?

#8).
The volume of a cone is (1/3) (pi) (radius of the round end)² (height)

That's the volume of the ice cream cone alone.

The volume of a sphere is (4/3) (pi) (radius)³

The glob of ice cream on top is 1/2 of a sphere.
The sphere and the cone in this problem both have the same radius.

#9).
The volume of a cylinder is (pi) (radius of the round end)² (height)

#10).
Another cylinder !
The volume of a cylinder is (pi) (radius of the round end)² (height)

What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit?

Akimi4 [234]

Answer:

25.6 units

Step-by-step explanation: From the figure we can infer that our triangle has vertices A = (-5, 4), B = (1, 4), and C = (3, -4).

First thing we are doing is find the lengths of AB, BC, and AC using the distance formula:

d=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}

where

(x_1,y_1) are the coordinates of the first point

(x_2,y_2) are the coordinates of the second point

- For AB:

d=\sqrt{[1-(-5)]^{2}+(4-4)^2}

d=\sqrt{(1+5)^{2}+(0)^2}

d=\sqrt{(6)^{2}}

d=6

- For BC:

d=\sqrt{(3-1)^{2} +(-4-4)^{2}}

d=\sqrt{(2)^{2} +(-8)^{2}}

d=\sqrt{4+64}

d=\sqrt{68}

d=8.24

- For AC:

d=\sqrt{[3-(-5)]^{2} +(-4-4)^{2}}

d=\sqrt{(3+5)^{2} +(-8)^{2}}

d=\sqrt{(8)^{2} +64}

d=\sqrt{64+64}

d=\sqrt{128}

d=11.31

Next, now that we have our lengths, we can add them to find the perimeter of our triangle:

p=AB+BC+AC

p=6+8.24+11.31

p=25.55

p=25.6

We can conclude that the perimeter of the triangle shown in the figure is 25.6 units.

the sales tax in your city is 4.4%.and an item costs $3 before tax. how much tax would you pay on that item

MrMuchimi

<h2>Greetings</h2>

Answer:

The tax is $0.12

Step-by-step explanation:

If you can imagine that price of $3 to be 100% of the price, you can simply add 4.4 onto this to find the percentage you need to find of the price:

100 + 4.4 = 104.4

So now you can use the percentage formula:

Amount x $\frac{percentage}{100}$

Simply plug all the values into this:

3 x $\frac{104.4}{100}$

3 x 1.04 = 3.12

Now you have the total price and you can simply minus the item cost without tax:

3.12 - 3 = 0.12

<h3>So the tax is $0.12!</h3><h3 /><h2>Hope this helps!</h2>
