<h2>Answer:</h2><h2>(i) Total expenses = $ 300</h2><h2>(ii) Net income(savings) = $ 0</h2>

Step-by-step explanation:

Total income earned by Sam = $ 300

(i) Expense calculation,

Clothes expense = 30 % = 30 % (300) = $ 90

Food and snacks expense = 23 % = 23 % (300) = $ 69

Cell phone expense = 14% = 14% (300) = $ 42

Transportation expense = 10% = 10% (300) = $ 30

Gym expense = 10% = $ 30

Movies expense = 8% = 8% (300) = $ 24

Apps expense = 5% = 5% (300) = $ 15

Total expenses = (90 + 69 + 42 + 30 + 30 + 24 + 15) = $ 300

(ii) Sam's net income is the profir earned  after his expense.

Net income = 300 - 300 = $ 0

When a bush was first planted in a garden, it was 12 inches tall. After two weeks, it was 120% as tall as when it was first plan
e-lub [12.9K]

Answer:

The bush after the two weeks was 14.4 inches tall

Step-by-step explanation:

Let

x ----> bush height after two weeks

we know that

120\%=120/100=1.20

The bush height after two weeks is equal to multiply the height when it was first planted by 1.20

so

x=1.20(12)=14.4\ in

How to find the other endpoint of a line when only given the first endpoint and the midpoint?
Schach [20]
If we have a line, and the endpoints are(x₁,y₁) and (x₂,y₂), the midpoint will be:( (x₁+x₂)/2 , (y₁+y₂)/2 );

Data:
Endpoint₁: (2,-3)
Midpoint: (6,6)

Therefore:

(2+x₂)/2=6
2+x₂=12
x₂=12-2
x₂=10

(-3+y₂)/2=6
-3+y₂=12
y₂=12+3
y₂=15

Answer; the other endpoint of a line will be (10,15)

A motorboatcan go 8 miles downstream on a river in 20 minutes. It takes 30 minutes for the boat to go upstream the same 8 miles.
True [87]
<span>Let m = speed of motorboat
and c = speed of current
.
When going downstream, current speed is added to boat speed -- and, the total speed is "8 miles downstream in 20 minutes"
.
To convert to "miles per hour" we multiply by 60 mins per 1 hour:
(8 miles/20 mins) * (60 mins/1 hour) = 24 mph
.
This gives us our first equation (1):
m+c = 24
.

When going upstream, the boat speed is reduced by the current -- and, the total speed is "8 miles in 30 minutes".
To convert to "miles per hour" we multiply by 60 mins per 1 hour:
(8 miles/30 mins) * (60 mins/1 hour) = 16 mph
.
This gives us our second equation (2):
m-c = 16
m = 16+c
.
Plug the above into equation 1 and solve for c:
m+c = 24
16+c+c = 24
16+2c = 24
2c = 8
c = 4 mph </span>
