Noah pays $25.20 for non perishable food items to give to the local homeless shelter the price includes a 5% sales of tax. what is the price before tax of the food items?
Answer:
$24
Step-by-step explanation:
From the information you have that the price of items is $25.20 and it includes a 5% tax. From this, you can write the following:
x+0.05x=25.20
Then, you can isolate x to find the price before tax:
1.05x=25.20
x=25.20/1.05
x= 24
According to this, the price before tax of the food items is $24.
Kevin says that lines p and m will eventually intersect.
Lines A and B intersect. Plane A contains lines p, m, and n. Line n is horizontal on the plane. Lines p and m are both going in the same direction and are identical. Plane B contains vertical line l which forms a right angle with line n.
Is Kevin correct?
No, because they are non-coplanar.
No, because they are parallel.
Yes, because they are perpendicular.
Yes, because they are coplanar.
Answer:
No, because they are parallel.
Kevin says that lines p and m will eventually intersect. The statement is incorrect because lines p and m are parallel.
What are parallel and perpendicular lines?Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.
It is given that lines A and B intersect. Plane A contains lines p, m, and n. Line n is horizontal on the plane. Lines p and m are both going in the same direction and are identical. Plane B contains vertical line l which forms a right angle with line n.
In the image attached with the answer below it is observed that the two lines p and m are in the same plane and are parallel to each other.
Therefore, the statement given by Kevin is incorrect.

Sandra is a lawyer. She is working on x number of cases. She gets 8 more cases to work on. She now has more than 29 cases that she is working on. Which inequality could be used to figure out how many cases Sandra is working on? * Answers. 8x > 29 x + 8 29 x - 8 < 29
Answer:
The inequality that can be used to figure out how many cases Sandra is working on is: [tex]x + 8 > 29[/tex]
Step-by-step explanation:
She is working on "x" cases, then she adds 8 more to that number, therefore it is "x + 8" and we also know that the total number of cases she's working is more than 29, in other words, it is greater than 29. With this in mind we can create the following inequality:
[tex]x + 8 > 29[/tex]
The inequality that can be used to figure out how many cases Sandra is working on is: [tex]x + 8 > 29[/tex]

Answer:
50 = x
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
105 = 55+x
Subtract 55 from each side
105-55 = 55-55+x
50 = x
Answer:
A
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
105° is an exterior angle of the triangle , thus
x + 55 = 105° ( subtract 55 from both sides )
x = 50° → A

A school has a track that is made up of a rectangle with two semicircles at each end, as pictured. The perimeter of the track, P, is 395 m. The rectangular part of the track will be covered with grass. The grass comes in pieces that each have an area of 1.35 square metres. Determine the minimum number of pieces of grass required to cover the rectangular part of the track.
Answer:
4502 pieces of grass
Step-by-step explanation:
The radius of the semicircle is 36 meters, so its perimeter is:
Perimeter = pi * radius = 113.097 m
The perimeter of both semicircles is 2 * 113.097 = 226.194 m
So if the total perimeter is 395, the length of the rectangle is:
395 = 226.194 + 2*length
2*length = 168.8
length = 84.4 m
The width of the rectangle is 2 times the radius of the semicircle, so:
width = 2 * 36 = 72 m
Then the area of the rectangle is:
Area = length * width = 84.4 * 72 = 6076.8 m2
To find the number of grass pieces, we divide the rectangle area by the grass piece area:
number of pieces = 6076.8 / 1.35 = 4501.33 pieces
So we will need 4502 pieces to cover the rectangular area.

Step-by-step explanation:
Some students are trying to write an expression with fewer terms that is equivalent to 8 - 3(4 - 9x). Noah says, "I worked the problem from left to right and ended up with 20 - 45x." 8 - 3(4 - 9x) 5(4 - 9x) 20 - 45x Lin says, "I started inside the parenthesis and ended up with 23x." 8 - 3(4 - 9x) 8 - 3(-5x) 8 + 15x 23x Jada says, "I used the distributive property and ended up with 27x - 4." 8 - 3(4 - 9x) 8 - (12 - 27x) 8 - 12 - (-27x) 27x - 4 Andre says, "I also used the distributive property, but I ended up with -4 - 27x." 8 - 3(4 - 9x) 8 - 12 - 27x -4 - 27x Do you agree with any of them? Explain your reasoning.
Answer: Yes I agree with Jada. His approach is correct.
Step-by-step explanation: The question requires the student to write an equivalent equation with fewer terms. Nonetheless, this does not prevent applying a mathematically correct approach.
(1) Noah is wrong and the reason is that the initial step is mathematically incorrect. The expression on the right hand side reads 3(4 - 9x), therefore starting with "8 - 3" is very wrong. The right step was to take one side which is 8 and take the other side which is 3(4 - 9x).
(2) Lin is wrong and the reason is that she started inside the parenthesis and this also is mathematically incorrect. The digits inside the parenthesis are "not like terms" and hence calculating 4 - 9x = -5x is very incorrect (the same way you cannot correctly calculate 500 metres minus 200 inches. You must make sure they are both in meters or in inches, that is both must be like terms).
(3) Jada is very correct in using the distributive property and ended up with the only correct solution. The digits on the right hand side of the expression was solved first and that resulted in -12 + 27x. The reason being that the number outside the parenthesis which is -3, multiplied both digits inside the parenthesis. The minus sign had a major effect, and after simplifying the right hand side the expression now becomes;
8 - 12 + 27x
Since the like terms are 8 and 12, you can simplify further to become
- 4 + 27x OR the expression can be rearranged as 27x - 4
(4) Andre is not correct and the reason is that although he used the distributive property, he made a slight mistake while solving for the right side of the expression. What Andre did was
-3(4 - 9x)
-12 - 27x
Remember that when a negative value multiplies another negative value the answer is positive. Therefore -3 times -9x should have been +27x, just like Jada did as shown above.
From that point onward, his answer would be incorrect.

Where π = 3.14...
Answer:
πr2.

In pentagon $MATHS$, $\angle M \cong \angle T \cong \angle H$ and $\angle A$ is supplementary to $\angle S$. How many degrees are in the measure of $\angle H$?
Answer:
H = 120°
Step-by-step explanation:
The sum of the internal angles of a polygon with n sides is given by the formula:
S = (n-2)*180
So, for a pentagon, we have n = 5, then:
S = (5-2)*180 = 540°
So we have that:
M + A + T + H + S = 540° (eq1)
M = T = H (eq2)
A + S = 180° (eq3)
Using the second and third equation in the first one, we have:
H + H + H + 180 = 540
3H = 360
H = 120°
