Answer:

x = 14, y = 37.

Step-by-step explanation:

9x + 12 = 4y - 10 (exterior alternate angles are equal)

9x - 4y = -22 ..........A

The angle which is interiorly alternate to 3x is 180 - (9x + 12), so:

3x = 180 - (9x + 12) (interior alternate angles are equal)

3x + 9x = 168

12x = 168

x = 14

Substitute x = 14 into equation A:

9(14) - 4y = -22

4y = 9(14) + 22

4y = 148

y = 37.

The net of a square pyramid is shown: What is the surface area of the figure? (A)0.7625 square inch

aniked [119]

Answer:

C. 0.6625 square inches

Step-by-step explanation:

To get the area of the net of a square pyramid;

We need to find the are of the square base and the area of the four triangles;

Area of the square base = s²

= (0.25 in)²

= 0.0625 in²

Area of one triangle = 0.5 × b × h

= 0.5 × 0.25 in × 1.2 in

= 0.15 in²

Area of the four triangles = 0.15 in² × 4

= 0.6 in²

Therefore;

Area of the net square pyramid = 0.0625 in² + 0.6 in²

= 0.6625 square inches

Can someone help me out please, thank you.

Here are a few rules about exponents you should know:

Multiplying exponents of the same base: $x^m*x^n=x^{m+n}$
Dividing exponents of the same base: $\frac{x^m}{x^n}=x^{m-n}$
Powering a power to a power: $(x^m)^n=x^{m*n}$
Converting a negative exponent into a positive one: $x^{-m}=\frac{1}{x^m};\frac{1}{x^{-m}}=x^m$

Firstly, multiply the y bases: $\frac{z^5}{(-y^{-4}y^{-1}x^3)^{-3}}=\frac{z^5}{(-y^{-4+-1}x^3)^{-3}}=\frac{z^5}{(-y^{-5}x^3)^{-3}}$

Next, solve the power: $\frac{z^5}{(-y^{-5}x^3)^{-3}}=\frac{z^5}{-y^{-5*-3}x^{3*-3}}=\frac{z^5}{-y^{15}x^{-9}}$

Finally, convert the negative exponent into a positive one and <u>your final answer will be: $-\frac{z^5x^9}{y^{15}}$ </u>
