Answer:

60 (C).

Step-by-step explanation:

FIrst off, the part that's most likely confusing you is the exponents and parenthesis. The exponents, if outside the parenthesis, affect everything inside the parenthesis. If the exponents are inside the parenthesis, however, they only affect the numebr they are attached to.

5+4 = 9, so 9^2 - (5 + 4^2).

4^2 = 16.

9^2 = 81.

81 - (5 + 16) = 81 - 21.

81 - 21 = 60.

Someone, please help me with this question.

Viefleur [7K]

Answer:

C. 95°

Step-by-step explanation:

Sumplementary angles sum 180°

144° + a = 180°

a = 180° - 144°

a = 36°

121° + b = 180°

b = 180° - 121°

b = 59°

The sum of internal angles of a triangle is 180°

a + b + c = 180°

36° + 59° + c° = 180°

c° = 180° - (36°+59°)

c° = 180° - 95°

c° = 85°

then:

c + n = 180°

85° + n = 180°

n = 180° - 85°

n = 95°

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.

hammer [34]

Answer: option d.

Step-by-step explanation:

If <em>y </em>varies directly as <em>x</em> and <em>z</em>, the form of the equation is:

$y=kxz$

Where<em> k</em> is the constant of variation.

If y=4 when x=6 and z=1 then substitute these values into the expression and solve for <em>k:</em>

$4=k(6)(1)\\4=6k\\k=\frac{4}{6}\\\\k=\frac{2}{3}$

<em> </em>Substitute the value of <em>k</em> into the expression. Then, the equation is:

$y=\frac{2}{3}xz$

To find the value of <em>y </em>when x=7 and z=4, you must substute these values into the equation. Therefore you obtain:

$y=k=\frac{2}{3}(7)(4)$

$y(7,4)=\frac{56}{3}$
