6 + 3 3/8
Add the whole number parts, 6 + 3 = 9
Then add the 3/8 to the end.
9 3/8

If needed as an improper fraction:
8 * 9 = 72 + 3 = 75/8

THIS IS URGENT I NEED HELP ASAP.(9x 10^-3)^2

joja [24]

(9x 10^-3)^2= $\frac{81x^{2}}{1000000}$ , so d 8.1x10^-6

Evaluate 1/2a^-4b^2 for a =-2 and b=4

$\frac{1}{2} (-2)^{-4} *4^{2}\\\\\frac{1}{2} *\frac{1}{(-2)^{4}} *4^{2}\\\\\frac{1}{2} *\frac{1}{2^{4}}*4^{2}\\\\\frac{1}{2} *\frac{1}{16}*4^{2}\\\\\frac{1}{2} *\frac{1}{16}*16=\frac{1}{2}$

A number raised to a negative exponent is sometimes negative.

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Solid: A square pyramid. The square base has side lengths of 5. The 4 triangular sides have a base of 5 and height of 7. What is

lina2011 [118]

Answer:

95 square units

Step-by-step explanation:

Surface area of pyramid = 4(side area) + base

Solve for the base first.

Area of base = s*s = 5*5 = 25

Next solve for one of the sides.

Area of triangle = 1/2 b*h = 1/2 5*7 = 17.5

Plug these back into our original equation.

Surface area of pyramid = 4(side area) + base

Surface area of pyramid = 4(17.5) + 25

Surface area of pyramid = 70 + 25 = 95 square units
