50 POINTS AND I WILL MARK BRAINLIEST Find the volume please help
ANEK [815]

Answer:348

Step-by-step explanation:

For composite prisms, where the bases are a composite shape, the area of the bases is the sum of the areas of the parts it is made of. The volume of the composite prism is then given by multiplying the whole base area by the height of the prism.In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.

1. There is no "h" in f(x) = log(x). The question is nonsense.

2. The log function is defined for arguments greater than zero. You're probably expected to select D, though A and B could also be correct.

3. Same deal. The log function is defined for x > -2, but the domain could be restricted to x > 2. You're expected to select FALSE.

4. Same deal. Choose B, though D is also correct.

5. C is the proper choice. (See discussion of the log function, above.)

A shop is having a sale all items are reduced work out the sale price of an item normally priced at £60
Naddik [55]

Question:

A shop is having a sales all items are reduced by 25%. Work out the sale price of an item normally priced at £60?

Answer:

The new price is £45

Step-by-step explanation:

Given

Sales\ price = \pounds 60

Rate = 25\%

First, calculate the reduction

Reduction = Rate * Sales\ price

Reduction = 25\% * \pounds 60

Reduction = \pounds 15

The new price is:

New = Sales\ price - Reduction

New = \pounds 60 - \pounds 15

New = \pounds 45
