Find the value of m so that the line y = mx - 5 will pass through the point (-2,3).
Answers
Answer:
Step-by-step explanation:
b/c there is a -5 we know that the line will pass through point (0,-5) and we also want the line to pass through (-2,3) so use those two points to find the slope
m = 3-(-5) / -2 -0
m = 3+5 / -2
m = -8/2
m = -4

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%

Option 1 , 2 & 5
Step-by-step explanation:
4 & 16 are perfect squares. So , 1/4 & 1/16 are also perfect squares. But 2 , 8 & 10 are not perfect squares. So root of 1/2 , 1/8 & 1/10 are irrational numbers.
Verification :-
1)[tex] \sqrt{ \frac{1}{10} } = \frac{ \sqrt{1} }{ \sqrt{10} } = \frac{1}{ \sqrt{2} \times \sqrt{5} } [/tex]
Hence , it is irrational.
2)[tex] \sqrt{ \frac{1}{8} } = \frac{ \sqrt{1} }{ \sqrt{8} } = \frac{1}{2 \sqrt{2} } [/tex]
So , it is irrational.
3)[tex] \sqrt{ \frac{1}{16} } = \frac{ \sqrt{1} }{ \sqrt{16} } = \frac{1}{4} [/tex]
So , it is rational.
4) [tex] \sqrt{\frac{1}{4} } = \frac{ \sqrt{1} }{ \sqrt{4} } = \frac{1}{2} [/tex]
So it is rational.
5) [tex] \sqrt{ \frac{1}{2} } = \frac{ \sqrt{1} }{ \sqrt{2} } = \frac{1}{ \sqrt{2} } [/tex]
Hence it is irrational.

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

Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{x}{13}[/tex] = [tex]\frac{32}{16}[/tex] = 2 ( multiply both sides by 13 )
x = 26
and
[tex]\frac{MP}{RT}[/tex] = [tex]\frac{MN}{RS}[/tex] , substitute values
[tex]\frac{y}{38}[/tex] = [tex]\frac{16}{32}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 38 ( divide both sides by 2 )

Castel and Gabriella are selling pies for a school fundraiser. Customers can buy apple pies and lemon meringue pies. Castel sold 6 apple pies and 4 lemon meringue pies for a total of $80. Gabriella sold 6 apple pies and 5 lemon meringue pies for a total of $94.
Could someone please walk me through the process of writing two systems of equations that represents the number of each type of pie????
Let x = cost of each apple pie; y = cost of each lemon meringue pie.
Thank you thank you so so much!
Answers
Step-by-step explanation:
Since Castel sold 6 apple pies and 4 lemon meringue pies for $80, we have 6x + 4y = $80.
Also Gabriella sold 6 apple pies and 5 lemon meringue pies for $94, we have 6x + 5y = $94.
6x + 5y = $94
- (6x + 4y = $80)
=> y = $14.
Therefore 6x + 5($14) = $94, 6x = $24, x = $4.
Hence each apple pie costs $4 and each lemon meringue pie costs $14.
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.

The area of a rectangle is 1,872 ft2. The ratio of the length to the width is 9:13. Find the perimeter of the rectangle. A. 88 ft B. 117 ft C. 168 ft D. 176 ft
Answers
Answer:
Length = 36
Width = 52
Step-by-step explanation:
Area of rectangle = Length * width
Length = L ; Width = W
Area (A) = 1872 ft²
Ratio L:W = 9:13
Hence,
1872 = lw - - - (1)
l/w = 9/13 - - - (2)
From (2)
13l = 9w
l = (9/13)w - - (3)
Put (3) into (1)
1872 = (9/13)w * w
1872 = 9/13 w²
24336 = 9w²
24336 / 9 = w²
2704 = w²
w = 52
If w = 52
1872 = 52 * l
l = 1872 / 52
l = 36
Length = 36
Width = 52

Work out the mean for the data set below:
4.7, 4.2, 8.2, 9.5, 3.1
Answers
Answer:
5.94
Step-by-step explanation:
To find the mean, you need to add the numbers and divide it by however many numbers you have.
4.7 + 4.2 + 8.2 + 9.5 + 3.1 = 29.7
There are 5 numbers, so divide the sum by 5
29.7/5 = 5.94
The mean of the data set 4.7, 4.2, 8.2, 9.5, 3.1 will be 5.94.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers.
The data set is given below.
4.7, 4.2, 8.2, 9.5, 3.1
Then total number of the term are 5.
Then the mean will be
Mean = (4.7 + 4.2 + 8.2 + 9.5 + 3.1) / 5
Mean = 29.7 / 5
Mean = 5.94
