B = g + 12
g + b = 124
Replace the b in the second equation with
g+ 12

g+ g+12=124
2g + 12 = 124
Subtract 12 from both sides
2g = 112
Divide by 2
g = 56

b= 56 + 12
b= 68

sweet-ann [11.9K]

12-pack for 1.69 is a better buy

<em><u>Solution:</u></em>

Given that, Mike bought a 12-pack for 1.69 and Mary bought a 24-pack for 3.18

We have to find which is the better buy

First we have to find the unit rate

Unit rate is cost of 1 pack

<em><u>Mike bought a 12-pack for 1.69</u></em>

Therefore,

Cost of 12 pack = 1.69

Cost of 1 pack is found by dividing 1.69 by 12

cost\ of\ 1\ pack = \frac{1.69}{12} = 0.14083

Thus unit rate of Mike is 0.14083 dollar per pack

<em><u>Mary bought a 24-pack for 3.18</u></em>

Cost of 24 pack = 3.18

Cost of 1 pack is found by dividing 3.18 by 24

cost\ of\ 1\ pack = \frac{3.18}{24} = 0.1325

Thus unit rate of Mary is 0.1325 dollars

<em><u>On comparing both the unit rate</u></em>

0.14083>0.1325

Thus unit rate of Mike is larger

Thus, 12-pack for 1.69 is a better buy

What is the axis of symmetry for f(x) = -3x2 + 18 - 7
solong [7]

The vertex form:

y=a(x-h)^2+k\\\\(h,\ k)-vertex

The axis of symetry is x = h.

y=ax^2+bx+c\to h=\dfrac{-b}{2a}

We have

f(x)=-3x^2+18x-7\to a=-3,\ b=18,\ c=-7

Substitute:

h=\dfrac{-18}{(2)(-3)}=\dfrac{-18}{-6}=3

<h3>Answer: x = 3</h3>

What is the description of angle 4 as it relates to the situation below?
Murljashka [212]

Answer:

The correct option is 1.

Step-by-step explanation:

The angle of elevation is the angle formed by the line of sight and the horizontal plane for an object above the horizontal.

The angle of depression is the angle formed by the line of sight and the horizontal plane for an object below the horizontal.

Since the angle 4 is the angle between the line of sight and the ground for an object above the horizontal, therefore angle 4 is the angle of elevation from the person to the radar tower.

1. "Angle 4 is the angle of elevation from the person to the radar tower."

This statement is true.

2. "Angle 4 is the angle of depression from the radar tower to the person".  

This statement is is false.

3. "Angle 4 is the angle of depression from the person to the radar tower".

This statement is false.

4. "Angle 4 is the angle of elevation from the radar tower to the person".

This statement is false.
