Answer:

22.8 ounces

Step-by-step explanation:

Since one red box weighs 15.2 ounces, three red boxes weigh 45.6 ounces. This is the same as two blue boxes, so we have the equation 2b=45.6 where b represents the weight of the blue box. Solving the equation by multiplying both sides by 1/2 gives us 22.8 ounces.

Find the equation of the graph given below. Notice that the sine function is used in the answer template, representing a sine fu
Gnoma [55]

Answer:

y = 2sin(x/2 - pi/4) + 1

Step-by-step explanation:

The normal sine has a range of [-1, 1]. This one has a range of [-1, 3], so the amplitude is 2 times higher (4 vs 2).

After that, 2sin(x) has a range of [-2, 2], but this one has a range of [-1, 3], so we need to shift it upwards by 1.

We now know that the answer is 2sin(____)+1.

A normal sine has it's middle point while rising at x = 0, but this one has it at x = pi/2 - so we need to shift a sine to the right by pi/2.

Lastly, a sine has a cycle of length 2pi, but this one has a cycle of length 4pi. We can achieve that by dividing the argument 2.

We now know that the answer is 2sin(x/2 - pi/4) + 1. We can plot it to verify.

Caleb earns points on his credit card that he can use towards future purchases. He earns four points per dollar spent on flights
Doss [256]
Given:
Flights: 4 points per dollar
Hotels: 2 points per dollar
Other: 1 point per dollar.
Total spent = $9,480
Points earned = 14,660

Let
x = money spent on flights
y = money spent on hotels
z = money spent on other purchases.

Because the money spent on flights was $140 more than twice the money spent on hotels, therefore
x = 2y + 140          (1)

Total charges were $9,480, therefore
x + y + z = 9480    (2)

Total points earned was 14,660. Therefore
4x + 2y + z = 14660   (3)

Subtract (2) from (3).
4x + 2y + z - (x + y + z) = 14660 - 9480
3x + y = 5180             (4)
Substitute (1) into (4).
3(2y + 140) + y = 5180
7y + 420 = 5180
7y = 4760
y = 680
From (1), obtain
 x = 2y + 140 = 2*680 + 140 = 1500
From (2), obtain
 z = 9480 - (x + y) = 9480 - (1500 + 680) = 7300

Answer:
$1,500 was spent on flights,
$680 was spent on hotels,
$7,300 was spent on other purchases.
