Answer:

6.7 or 6 7/10

Step-by-step explanation:

You'll be using PEMDAS. First, parenthesis.

(5.2+6.3) this is equal to 11.5

Since you don't have any exponents, you'll move on to multiplication and division, so -12÷2.5. This equals -4.8.

(When you divide any number by a negative number, the result will be negative)

Now you're left with 11.5-4.8, which equals 6.7.

This is what it would look like written out:

(5.2+6.3)-12÷2.5

11.5-12÷2.5

11.5-4.8

6.7

Hope this helps!

Suppose you have one pyramid with a base that is 10 meters long and 10 meters wide with a slant that is 15 meters. Now, if the l

Answer:

The difference between area of pyramids is 125 sq.m.

Step-by-step explanation:

Length of base = 10m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid = $\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10$

Area of pyramid = 400 sq.m.

Now the length of base is increased to 15

Length of base = 15m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid = $\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10$

Area of new pyramid = 525 sq.m.

Difference between area of pyramids=525 sq.m. - 400 sq.,. = 125 sq.m.

Hence The difference between area of pyramids is 125 sq.m.
