2^8-10-15÷3<br><br> can you help me plzzzz
GenaCL600 [577]

Answer:

241

Step-by-step explanation:

Simplify the following:

2^8 - 10 - 15/3

The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:

2^8 - 10 + -5

2^8 = (2^4)^2 = ((2^2)^2)^2:

((2^2)^2)^2 - 10 - 5

2^2 = 4:

(4^2)^2 - 10 - 5

4^2 = 16:

16^2 - 10 - 5

| 1 | 6

× | 1 | 6

| 9 | 6

1 | 6 | 0

2 | 5 | 6:

256 - 10 - 5

256 - 10 - 5 = 256 - (10 + 5):

256 - (10 + 5)

10 + 5 = 15:

256 - 15

| 2 | 5 | 6

- | | 1 | 5

If the lengths of the sides of a triangle measure 5/4 m 3/2 m and 1/8 m, determine its perimeter.
atroni [7]

Answer:

23/8

Step-by-step explanation:

To find the perimeter of the triangle we need to add all the sides. Since the sides all have different denominators in their fractions, first we need to make the denominator the same.

5/4 = 10/8

3/2 = 12/8

1/8 = 1/8

Then we just add the numerators and keep the denominator the same, which gets us 23/8 meters. Since 23/8 can be simplified, that's the answer.

What is the volume of this oblique cone? 12π cm³ 40π cm³ 60π cm³ 120π cm³ An oblique cone with radius of six centimeters and hei
Pepsi [2]

We have to find the volume of oblique cone. An oblique cone is a special type of cone in which the apex is not located directly above the center of the circular base, so it looks like a slanted cone.

Volume of oblique cone = \frac{1}{3} \Pi r^{2}h

where 'r' is the radius and 'h' is the height.

Here r = 6 cm and h = 10 cm

Volume = \frac{1}{3} (\Pi (6)^{2} \times 10)

= \frac{360\Pi }{3}

= 120\Pi cm^{3}

So, the volume of the given oblique cone is 120\Pi cm^{3}.

Option 4 is the correct answer.
