My number has a tens digit that is 8 more than the ones digit. Zero is not one of my digits. Write the 2-digit number that match

pochemuha

Answer:

The number is 91

Step-by-step explanation:

Let x be the ones place digit and y be the tens place digit,

Then the number would be 10y + x,

We have,

y - x = 8

Possible values of y and x = { (8, 0), (9, 1) }

∵ 0 is not the digit of the number,

Hence, y = 9 and x = 1

Therefore, required number = 10(9) + 1 = 90 + 1 = 91

What is the surface area of the pyramid shown to the nearest whole number? the diagram is not drawn to scale

Citrus2011 [14]

Answer:

(B) $SA=72{\tex{feet^2}$

Step-by-step explanation:

Given: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.

To find: The Surface are of Pyramid.

Solution: From the figure, it is given that the length of the base is 4 feet and slant height is 7 feet.

Now, surface area of the Pyramid is given as:

$SA={\text{Area of base}+\frac{1}{2}pl$

where p is the perimeter and l is the slant height.

Now, area of base is given as:

$A=4(4){\tex{ft^2}$

$A=16{\tex{ft^2}$

And, the surface area is given as:

$SA=16+\frac{1}{2}(4)(4)(7)$

$SA=16+56$

$SA=72{\tex{feet^2}$

Hence, option B is correct.
