Trina and Jessie went on a vacation to Hawaii. Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level. Jessie went hang-gliding and reached an altitude of 87.9 meters, which is above sea level. Who is closer to the surface of the ocean?
Answers
Answer:
Step-by-step explanation:
LEt the surface of the ocean be at the zero level i.e at 0metres
If Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level, the distance between Trina and the sea level will be:
D = 0-(-85.6)
D = 0+85.6
D = 85.6m
If Jessie went hang-gliding and reached an altitude of 87.9 meters, the distance between Jessie and the sea level will be:
D = 87.9-0
D = 87.9m
Since the distance of Trina is less than that of Jessie, this means that Trina is closer to the surface of the ocean
Another store, Healthy Pets, sells dog food in 50-pound bags for $92.13 per bag. If one bag of food from Pets Galore costs $48.15, how much would Seth save by buying 150 pounds of dog food from Pets Galore instead of from Healthy Pets?
Answers
Answer:
$140.91
Step-by-step explanation:
50 pounds = 1 bag
150 pound bags = 150 ÷ 5
3 bags
Another store, Healthy Pets, sells dog food in 50-pound bags for $92.13 per bag.
1 bag = $92.13
3 bags = x
Cross Multiply
x = 3 × $92.13
$276.39
If one bag of food from Pets Galore costs $48.15
1 bag = $48.15
3 bags = x
x = 3 × $48.15
x = $135.48
The amount would Seth save by buying 150 pounds of dog food from Pets Galore instead of from Healthy Pets is
$276.39 - $135.48
= $140.91

The Call First cell phone company charges $45 per month and an additional $0.24 for each text message sent during the month. Another cell phone company, Cellular Plus, charges $65 per month and an additional $0.23 for each text message sent during the month.
Answers
Answer:
2000
Step-by-step explanation:
Let [tex]x[/tex] be the total number of text messages sent per month in order for the plans to cost the same each month.
The first cell phone company, The Call, charges $45 per month and $0.24 per text message for the month.
So, the total cost as per the plan of The Call, for x text messages during the month, is
[tex]C_1= 45+0.24x\cdots(i)[/tex]
Another cell phone company, Cellular Plus, charges $65 per month and $0.23 per text message for the month.
So, the total cost as per the plan of Cellular Plus, for x text messages during the month, is
[tex]C_2= 65+0.23x\cdots(ii)[/tex]
As the cost for both the companies are the same, so, compute the number of text messages, x, during the month by equation [tex]C_1[/tex] and [tex]C_2[/tex] from equation (i) and (ii), we have
[tex]C_1=C_2[/tex]
[tex]\Rightarrow 45+0.24x=65+0.23x[/tex]
[tex]\Rightarrow 0.24x - 0.23x=65-45[/tex]
[tex]\Rightarrow 0.01 x = 20[/tex]
[tex]\Rightarrow x = 20/0.01[/tex]
[tex]\Rightarrow x= 2000[/tex]
Hence, there must be 2000 text message to be sent during the month in order to have the same cost from both the companies.

Eight teams of high school students helped clean up trash in the community. Afterwards, they shared 47 pizzas equally. How many pizzas did each team get?
Answers
Answer:
We know that 8 teams of students shared 47 pizzas.
The only thing we can assume is that the 47 pizzas where divided evenly between the teams, so the number of pizzas that each team gets is equal to the quotient between 47 and 8, or:
47/8 = 5.875
But this is not a whole number, and this happens because 47 is not a multiple of 8.
Then we can do:
47 = 40 + 7
And 40 is a multiple of 8.
40/8 = 5
Then each team got 5 whole pizzas, and there are 7 pizzas left.
Now, we can assume that each pizza has 8 slices.
Then there are left 7*8 = 56 slices.
And when we divide those by the number of teams, we have:
56 /8 = 7
So each team gets 7 slices from the remainder pizzas.
Then we can conclude that each team gets 5 whole pizzas and 7 slices.

You found a unit rate that compares dollars earned per hours worked at the coffee shop.Is there another unit rate you could write for this relationship? What does that unit ratemean in the context of the situation? What is the related constant of proportionality?
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. However, I'll assume the following.
Unit Rate = $10 per 2 hours
Solving further, we have that:
1. Yes, there is another unit rate that can be written.
Unit Rate = $10 per 2 hours
Convert Rate to fraction
[tex]Unit\ Rate = \frac{\$10}{2\ hours}[/tex]
Divide numerator and denominator by 2
[tex]Unit\ Rate = \frac{\$5}{1\ hour}[/tex]
Simplify:
[tex]Unit\ Rate = $5/hour[/tex]
2. The unit rate implies that the earnings is $5 per hour
3. The constant of proportionality
Let y represent the earnings
x represent work hours.
We have:
[tex]y = kx[/tex]
Where k = constant of proportionality
In this case:
[tex]y = 10[/tex]
[tex]x = 2[/tex]
Substitute these values in [tex]y = kx[/tex]
[tex]10 = k * 2[/tex]
[tex]10 = 2k[/tex]
Divide both sides by 2
[tex]5 = k[/tex]
[tex]k = 5[/tex]
Hence: The unit of proportionality is 5

Answers
Answer 2x and 7y
Step-by-step explanation:
Question:
Find 4 possible solutions in the context of the problem.
The 4 possible solutions in the context of the problem are (0, 8), (3, 6), (6, 3), and (9, 2)
Given the equation that models the situation expressed as:
4x + 6y = 48
We are to find 4 possible solutions for x and y. Note that the values of x and y must be integers.
If there are no cars i.e. at when x = 0
4(0) + 6y = 48
0 + 6y = 48
6y = 48
y = 48/6
y = 8
One of the solution is (0, 8)
If there are 3 cars, i.e. at when x = 0
4(3) + 6y = 48
12 + 6y = 48
6y = 48 - 12
y = 36/6
y = 6
The second solution will be (3, 6)
If there are 6 cars, i.e. at when x = 6
4(6) + 6y = 48
24 + 6y = 48
6y = 48 - 24
y = 24/6
y = 4
The third solution will be (6, 3)
If there are 9 cars, i.e. at when x = 9
4(9) + 6y = 48
36 + 6y = 48
6y = 48 - 36
y = 12/6
y = 2
The fourth solution will be (9, 2)
Hence the 4 possible solutions in the context of the problem are (0, 8), (3, 6), (6, 3), and (9, 2)
