How to find percents of numbers using multiples of 100, 10, and 1%?

Answers
Answer:
Im not too sure what the question is
Step-by-step explanation:
but when finding the percent of any number, 10% will always move the decimal over to the left once. So 10% of 300 is 30.0 This also works for 1%, you just move the decimal over twice. So 1% of 300 is 3

Sue makes and sells cupcakes. If she has a cost of $1,500 per year plus a cost of $1 per cupcake, how many cupcakes must she sell in order to make a profit if each cupcake sells for $3?
Answers
Answer:
751 cupcakes must be sold to make a profit
Step-by-step explanation:
From the question we are told that
Annual cost= $1,500 per year plus a cost of $1 per cupcake
Each cup cake sell at $3
Generally the profit off the top of each cupcake is $2
Therefore
[tex]\frac{1500}{2}=750[/tex]
This implies that 750 cupcakes will be sold to cover the annual cost excluding cupcake cost
Generally
751 cupcakes=$1502
Total Annual cost to make a profit
[tex]1(cost\ of\ each\ cupcake)*751+1500=\$2251[/tex]
Total Annual sale
[tex]3(sale of each cupcake)*751=\$2253[/tex]
Mathematically
[tex]2253\$-2251\$=2\$[/tex]
Therefore
751 cupcakes must be sold to make a profit

Here:
The first point is (x1,y1)=(5,-3)
The first point is (x2,y2)=(-1,6)

In a system of two linear equations, the lines represented by each equation have the same slope. Which could be the total number of solutions to the system of equation
Answers
Answer:
Please see explanation
Step-by-step explanation:
A system of linear equations in two variables represents two lines on graph.
When both the lines have same slope, there can be two cases
Same slope with different y-interceptsWhen two lines have same slope and different y-intercepts, that means that both lines are parallel and parallel lines have no solution.
Same slope with same y-interceptsWhen the slope of both lines is same and the y-intercept is also same, this means that both the equations refer to the same line. This means that the system has infinite number of solutions.
A motorboat travels 172 km in 3 hours going upstream and 372 in 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Answers
Answer:
The rate of the boat is 75.17 km/h and the rate of the stream is 17.83 km/h
Step-by-step explanation:
System of Equations
Let's call:
B = speed (rate) of the boat in still water
S = speed (rate) of the stream
The boat travels 172 km in 3 hours when going upstream, that is when the speed of the stream subtracts its own speed. The speed is the distance divided by the time, thus:
[tex]\displaystyle B-S=\frac{172}{3}[/tex]
Multiplying by 3:
3B - 3S = 172 [1]
The boat travels 372 km in 4 hours downstream when the speed of the current adds to its own:
[tex]\displaystyle B+S=\frac{372}{4}=93[/tex]
B + S = 93
Solving for B:
B = 93 - S [2]
Substituting in [1]
3(93 - S) - 3S = 172
Operating:
279 - 3S - 3S = 172
279 - 6S = 172
Subtracting 279:
- 6S = 172 - 279
- 6S = -107
Multiplying by -1 and solving for S:
[tex]S = \frac{107}{6}\approx 17.83\ km/h[/tex]
From [2]:
[tex]B = 93 - \frac{107}{6}[/tex]
[tex]B=\frac{451}{6}\approx 75.17\ km/h[/tex]
When paying for a restaurant order, a customer spent $18.00 ( for tip and cost) for a $15.00 meal. What percent was the tip? *
Answers
Answer:
16.67%
Step-by-step explanation:
The customer spent a total of $18 on a $15 meal. This means that, if counting tax within the $15 meal, the tip is $3.
Divide 3 with the total cost:
3/18 = ~0.1667
Change to percentage. Simply move the decimal point to the right two place values, and add a percentage sign:
0.1667 to a percent = 16.67%
16.67% is your answer.

Triangle ABC is an isosceles triangle so base angles are equal. <A = 30° (given)
180 - 30 = 150°
150/2 = 75°
the little triangle is also isosceles. the original base angles have been bisected so the base angles are 37.5.
37.5 X 2 = 75°
180-75 = 105°
