Answer: To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

No, because if you work with fraction and do $\frac{3}{2}$ (3 eggs for every 2 cups) then you would be multiplying 3x4 and now you have tot do that to the demominator so she would need 8 cups of sugar

Step-by-step explanation:

800 times .035 (year 1) = 828

828 times .035 (y2) = 28.98 (add to 828)

856.98 times .035 = 29.99 (add to 856.98)

886.97 times .035 = 31.04 (add to 886.97)

918.01 times .035 = 32.13

918.01 plus 32.13 = 950.14

950.14

Raise the quality in parentheses to the indicated exponent, and slim lift the resulting expression with positive exponents.

SIZIF [17.4K]

For this case we have the following expression:

$(\frac {-27x ^ 0 * y ^ {- 2}} {54x ^ {- 5} * y ^ {- 4}}) ^ {- 2} =$

By definition we have to:

$a^0= 1$

So:

$(\frac {-27y ^ {- 2}} {54x ^ {- 5} * y ^ {- 4}}) ^ {- 2} =$

Simplifying:

$(\frac {-y ^ {- 2}} {2x ^ {- 5} * y ^ {- 4}}) ^ {- 2} =$

By definition of power properties we have to:

$(a ^ n) ^ m = a ^ {n * m}$

So, rewriting the expression we have:

$\frac {-y ^ {- 2 * -2}} {4x ^ {- 5 * -2} * y ^ {- 4 * -2}} =\\\frac {-y ^ {4}} {4x ^ {10} * y ^ {8}} =$

SImplifying:

$\frac {-y ^ {4-8}} {4x ^ {10}} =\\\frac {-y ^ {- 4}} {4x ^ {10}} =\\- \frac {1} {4x ^ {10} y^ {4}}$

Answer:

$- \frac {1} {4x ^ {10} y ^ {4}}$

Please help me with this

maks197457 [2]

Answer:

D. $Cos(Z) = \frac{5}{13}$

Step-by-step explanation:

Using trigonometric ratios formula, thus:

$Cos(Z) = \frac{Adjacent}{Hypotenuse}$

Reference angle = Z

Adjacent = 10

Hypotenuse = 26

Plug in the values into the formula

$Cos(Z) = \frac{10}{26}$

Simplify

$Cos(Z) = \frac{5}{13}$
