Final answer:
Juan breaks even on day 5 as the expression 16 + (–16) equals zero, indicating that his earnings match his expenses.
Explanation:
You've asked whether Juan breaks even on day 5 when he records the expression 16 + (–16). In mathematics, breaking even means that income equals expenses, resulting in a net change of zero. The expression Juan recorded represents earning 16 units of money and spending 16 units of money. The negative sign in front of the second number indicates money going out, which is his expense.
To determine if he breaks even, we add the amounts together: 16 + (–16) = 0. Since the sum is zero, Juan does not gain or lose any money, which means he does indeed break even on day 5.

If it costs a restaurant $11.90 to produce 2 white chocolate tortes and each torte is cut into 8 slices, how much does each slice cost to make?
Final answer:
To find the cost of each slice of white chocolate torte, divide the total cost to produce two tortes ($11.90) by the total number of slices (16), resulting in approximately 74 cents per slice.
Explanation:
Cost of Each Slice of White Chocolate Torte
To calculate the cost of each slice of white chocolate torte, we start by determining the total cost of producing the tortes. The restaurant's cost is $11.90 for 2 tortes, and each torte is cut into 8 slices. This means there's a total of 2 tortes × 8 slices/torte = 16 slices. Dividing the total cost by the number of slices gives us the cost per slice:
Total cost for 2 tortes: $11.90
Number of slices per torte: 8
Total number of slices: 2 tortes × 8 slices/torte = 16 slices
Cost per slice: $11.90 / 16 slices = $0.74375 per slice
Therefore, each slice costs approximately 74 cents to make.
What is the equation of a line that passes through the point (5, −4) and is parallel to the line whose equation is 2x + 5y = 10?
Rewrite the given equation in slope intercept form:
5 y = 10 – 2 x
y = - 0.4 x + 2
Since the two lines are parallel, therefore they have similar slope which is – 0.4, so the equation is:
y = - 0.4 x + b
Given that x = 5, y = -4, find for b:
-4 = - 0.4 (5) + b
b = -2
So the answer is:
y = - 0.4 x – 2
or
2 x + 5 y = - 10

A rectangular porch has an area of 75 square feet.The length of the porch is 4 feet longer than the width.What is the width of the porch ?
The width of the porch is 5 feet.
Explanation:Let's denote the width of the porch as x. The length of the porch is then x + 4. The area of a rectangle is given by length x width. So, we can set up the equation x(x + 4) = 75 to find the width of the porch. Expanding the equation, we get x² + 4x = 75. Rearranging the equation, we have x² + 4x - 75 = 0. This quadratic equation can be factored as (x - 5)(x + 15) = 0. Since the width of the porch cannot be negative, we discard the x + 15 = 0 solution. Therefore, the width of the porch is 5 feet.

James buys a shirt and a pair of socks on sale for 25% off. if the price of the shirt before the sale was $24 and he spent a total of $24, what was the original price of the socks?
Answer:
The original price of socks was $8.
Step-by-step explanation:
James buys a shirt and a pair of socks on sale for 25% off.
The price of the shirt before the sale was $24 that means after discount the price was:
[tex]24-(0.25\times24)[/tex] = $18
And James paid a total of $24.
That means the price of socks after discount is = [tex]24-18[/tex] = $6
Let the original price of socks be x. And after 25% discount, it was for $6.
So, [tex]x-0.25x=6[/tex]
=> [tex]0.75x=6[/tex]
x = 8.
Hence, the original price of socks was $8.
What is the length of side AC of the triangle?
Enter your answers in the boxes.
Answer:
[tex]AC=25[/tex]
Step-by-step explanation:
From the given figure, it can be seen that [tex]{\angle}A={\angle}C[/tex], thus ΔABC is an isosceles triangle.
Therefore,[tex]AB=BC[/tex]
⇒[tex]5x+5=7x-1[/tex]
Solving the above equation, we get
⇒[tex]5x-7x=-1-5[/tex]
⇒[tex]-2x=-6[/tex]
⇒[tex]x=3[/tex]
Now, substituting the value of x in AC, we have
⇒[tex]AC=6x+7[/tex]
⇒[tex]AC=6(3)+7[/tex]
⇒[tex]AC=18+7[/tex]
⇒[tex]AC=25[/tex]
Thus, the length of the side AC of the given triangle is 25 units.
A cone is placed inside a cylinder as shown. The radius of the cone is half the radius of the cylinder. The height of the cone is equal to the radius of the cylinder. What is the volume of the cone in terms of the radius, r?
Answer:
Volume of the cone is [tex]\frac{1}{12}\pi r^{3}[/tex]
Step-by-step explanation:
Formula to find the volume of a cone is V = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here r is the radius of the cone and h is the height of the cone.
Since radius of cone = [tex]\frac{1}{2}(\text{Radius of cylinder})[/tex]
= [tex]\frac{r}{2}[/tex]
Height of the cone = radius of the cylinder = r
Now we put the values of radius and height of cone in the formula
Volume of cone = [tex]\frac{1}{3}\pi (\frac{r}{2})^{2}(r)[/tex]
= [tex]\frac{1}{3}\pi(\frac{r^{2}}{4})(r)[/tex]
= [tex]\frac{1}{12}\pi r^{3}[/tex]
Therefore, volume of the cone is [tex]\frac{1}{12}\pi r^{3}[/tex]

m∠WYX = (4x − 8)° and m∠WYZ = 10x°. If ∠WYX and ∠WYZ are complementary, find the measure of each angle.
Answer:
[tex]m\angle WYX=20^{\circ}[/tex]
[tex]m\angle WYZ=70^{\circ}[/tex]
Step-by-step explanation:
We have been given that [tex]m\angle WYX=(4x-8)^{\circ}[/tex] and [tex]m\angle WYZ=(10x)^{\circ}[/tex].
Since ∠WYX and ∠WYZ are complementary, so they will add up-to 90 degrees.
[tex]m\angle WYZ+m\angle WYX=90^{\circ}[/tex]
Substitute the given values:
[tex]4x-8+10x=90[/tex]
Combine like terms:
[tex]14x-8=90[/tex]
[tex]14x-8+8=90+8[/tex]
[tex]14x=98[/tex]
[tex]\frac{14x}{14}=\frac{98}{14}[/tex]
[tex]x=7[/tex]
Let us substitute [tex]x=7[/tex] in measure of each angle as:
[tex]m\angle WYX=(4(7)-8)^{\circ}[/tex]
[tex]m\angle WYX=(28-8)^{\circ}[/tex]
[tex]m\angle WYX=20^{\circ}[/tex]
Therefore, the measure of angle WYX is 20 degrees.
[tex]m\angle WYZ=(10x)^{\circ}[/tex]
[tex]m\angle WYZ=(10(7))^{\circ}[/tex]
[tex]m\angle WYZ=70^{\circ}[/tex]
Therefore, the measure of angle WYZ is 70 degrees.

Write the converse, inverse, and contrapositive for the following conditional statement. Determine whether the contrapositive is true or false and give reason why it is true or false.
Conditional Statement: If two segments are congruent, then they have the same length.
1.) Converse:
2.) Inverse:
3.) Contrapositive:
4.) Determine if the conditional statement below is TRUE OF FALSE. If False, provide a counterexample?
Conditional Statement:
If m∠A is greater than an acute ∠B, then ∠A must be obtuse.
The converse, inverse, and contrapositive of the given statement are provided. They are logically consistent with the original statement, pointing to the synonymous relationship between congruence and identical length in segments. The additional statement about angles is also factual, as one greater than an acute angle is, by definition, an obtuse.
Explanation:1.) Converse: If two segments have the same length, then they are congruent.
2.) Inverse: If two segments are not congruent, then they do not have the same length.
3.) Contrapositive: If two segments do not have the same length, then they are not congruent.
The contrapositive is true because it is a logical inverse of the original statement, which is also true. In geometry, congruent means being of the same size and shape, which directly implies having the same length.
4.) The statement: 'If m∠A is greater than an acute ∠B, then ∠A must be obtuse' is true. An acute angle is one that is less than 90 degrees. If ∠A is greater than this, it must be between 91 and 180 degrees, which by definition, makes it an obtuse angle.
