An angle measures 84° What is the measure of its supplement?

Lesechka [4]

Answer:

Supplement of 84° is 96°

Complement of 54° is 36°

Step-by-step explanation:

1) A supplementary angle is two angles that add up to 180°

so to find the supplement of 84° ⇒ 180°- 84° = 96°

2) A complementary angle is two angles that add up to 90°

so to find the complement of 54° ⇒ 90°- 54° = 36°

The owner of a grocery store finds she can sell about 982 gallons of milk in a week if she prices it at $2.99 per gallon. If she

julia-pushkina [17]

Answer:

g = -1110p +4300.9
804 gallons

Step-by-step explanation:

a) Price is the independent variable, so the data we are given can be written as ...

(price, gallons) = (2.99, 982) and (2.79, 1204)

Using the 2-point form of the equation for a line, we have ...

g = (g2 -g1)/(p2 -p1)(p -p1) +g1

g = (1204 -982)/(2.79 -2.99)(p -2.99) +982

g = -1110(p -2.99) +982 = -1110p +4300.9

g = -1110p +4300.9

b) When p = 3.15, the predicted sales volume is ...

g = -1110(3.15) +4300.9 = 804.4

Weekly sales are predicted to be 804 gallons at a price of $3.15.

Suppose in one year, total revenues from digital sales of pop/rock, tropical (salsa/merengue/cumbia/bachata), and urban (reggaet

Eduardwww [97]

Answer:

Pop/Rock sold $14 million
Tropical music sold $3 million
Reggaeton sold $4 million.

Step-by-step explanation:

First let's write the music genre as follows:

X = Pop/Rock
Y = Tropical
Z = Reggaeton

$\left \bigg \{ {{X + Y + Z = 21 (1) } \atop {X=2(Y + Z) (2)}} \text{; } \left \bigg \{ {{X + Y + Z = 21 (1)} \atop {X= Z + 10 (3)}$

Let's use $(2)$ in $(1)$ :

$X + Y + Z = 21 \Rightarrow 2(Y + Z) + Y + Z = 21 \Rightarrow\\3(Y+Z) = 21 \Rightarrow Y+Z = 7$

Then,

$X + 7 = 21 \Righarrow X = 14$

Now let's solve for Z,

$14 = Z +10 \Rightarrow Z = 4$

Finally, let's solve for Y,

$14 = 2(Y + 4) \Rightarrow Y + 4 = 7 \Rightarrow Y = 3$

So Pop/Rock sold $14 million, Tropical music sold $3 million and Reggaeton sold $4 million.
