4) A group entering a zoo purchased 33 admission tickets for a total of $139.50. Adult tickets (x) cost $7.50 and
tickets for children (y) cost $3.50. How many of each type of ticket were purchased?
/5 points
Answers
The number or children tickets are 24 and adults tickets are 9.
How to illustrate the information?Adult tickets (x) cost $7.50 and tickets for children (y) cost $3.50. The equation will be:
7.5x + 3.5y = 139.5
There are 33 tickets. This will be:
x + y = 33
x = 33 - y.
Recall 7.5x + 3.5y = 139.5
Substitute for x.
7.5(33 - y) + 3.5y = 139.5
247.5 - 7.5y + 3.5y = 139.5
-4.5y = 139.5 - 247.5
4.5y = 108
y = 108/4.5
y = 24
Number of children ticket = 24
Adult tickets = 33 - 24 = 9

Find WI if IE = 3
EW and YG are medians of XYW
Answers
Based on the definition of the median and applying the centroid theorem, the length of WI is calculated as: 6 units.
What is the Median of a Triangle?The line that joins the vertex of a triangle to the midpoint of the side it is directly opposite is called the median of a triangle.
Medians intersect each other at a point inside the triangle that is called the centroid. Based on the centroid theorem, since J is the centroid of triangle XYW, then:
the length of IE is one-third of the length of segment EW (referring to the image given in the question that shows triangle XYW)
Thus, we have the equation that relates the length of the segments as shown below:
IE = 1/3(EW)
Given that:
IE = 3 units
Substitute the value of IE into the equation:
3 = 1/3(EW)
3(3) = EW
9 = EW
EW = 9 units
Therefore:
Length of WI = the length of EW - the length of IE
Substitute
Length of WI = 9 - 3
Length of WI = 6 units.

The hypotenuse is the longest side of a triangle. It is ALWAYS the one across from the right angle (depicted as the box in the corner at 90 degrees). Therefore the 2 sides that intersect the 90-degree angle are "leg" and "leg" and the longest side is the"hypotenuse"
2)
The Pythagorean theorem states: [tex]a^{2} + b^{2} = c^{2}[/tex] where a and b are sides and c is the hypotenuse.
[tex]a^{2} + b^{2} = c^{2} \\8^{2} + 6^{2} = c^{2} \\64 + 36 = c^{2} \\100 = c^{2} \\\sqrt{100} = c\\10 = c[/tex]
For your purposes, a and b do not matter which number you choose as long as you make sure that they are sides and not the hypotenuse.
3)
The Pythagorean theorem states: [tex]a^{2} + b^{2} = c^{2}[/tex] where a and b are sides and c is the hypotenuse.
[tex]a^{2} + b^{2} = c^{2} \\4^{2} + 7^{2} = c^{2} \\16 + 49= c^{2} \\65 = c^{2} \\\sqrt{65} = c\\8.0622 = c[/tex]

Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure of one of the angles formed is 72degrees, what are the measures of the other three angles? Explain your answer. (15 points and brainliest)
Answers
72, 108, and 108 are the other three angles formed by the two straight lengths of wire.
What is termed as the vertical angles?When two lines intersect, the two angles that really are opposite each other are referred to as vertical angles. Vertical angles are so named not because they are oriented vertically, but because they share a same vertex, this same point of intersection between the two lines.For the given question.
Two straight lengths of wire are put on the ground, to form vertical angles.
Because vertical angles have always been congruent, 72 is the vertical angle to 72.
Because the line is straight, the answer is 180.
180 - 73 equal 108. (supplement angles)
Because they are both vertical angles, there are two 180s.
Thus, the three angles formed are 72, 180 and 180 degrees.

Answers
8 × [tex]10^5[/tex] is 200 times greater than 4 × [tex]10^3[/tex] as according to multiplying and dividing as per the scientific notation of multiplication and division.
What is scientific notation?A kind of representation of number which is some power of 1/10 can also be expressed in as easily in scientific notation.
1/10 = [tex]10^{-1[/tex] (“ten to the minus one power”)
More generally, the expression “[tex]10^{-n[/tex]” (where n is a whole number) means (1/10) n. Thus
[tex]10^{-3[/tex] = [tex]\frac{1}{10}^{-3}[/tex]
= 1/1000
[tex]10^{-8[/tex] = [tex]\frac{1}{10}^{-8[/tex]
= 1/100,000,000
Scientific notation was invented to help scientists (and science students) deal with very large and very small numbers, without getting lost in all the zeros.
Herein this question
8 × [tex]10^5[/tex] can also thus be written as 2 x 4 × [tex]10^5[/tex]. On dividing with 4 × [tex]10^3[/tex] we get 2 x [tex]10^2[/tex]. Thus, it is 2 x [tex]10^2[/tex] i.e., 200 times larger than 4× [tex]10^3[/tex].
The expression “10n”, where n can be stated as a whole number, simply means that “10 is raised to the nth power,” or in other words, a number that is got by using 10 as a factor n times.
You can also notice that the number of zeros that are present in the ordinary decimal expression is absolutely equal to the power to which thus 10 is raised.
If any kind of number is expressed in words, first we have to write it down as an ordinary decimal number and then we have to convert it. Thus, the value “ten million” becomes 10,000,000. There are a total of seven zeros, so in powers of ten notation ten million is written [tex]10^7[/tex].

Answers
The distance between Noor's house and her grandparent's house is 37.40 miles or if rounded off to the nearest tenth, it will be 40 miles using the estimation concept.
As per the question statement, Noor’s family is meeting her grandparents at a restaurant and the restaurant is 24.5 miles from Noor’s house but this is 65.5% of the distance from Noor’s house to her grandparents’ house.
We are supposed to find the distance between Noor's house and her grandparent's house. We will use the concept of estimation.
Distance between Noor's house and restaurant = 24.5 miles
Let distance between Noor's house and her grandparent's house be "x" miles.
So the distance between grandparent's house and restaurant = x - 24.5
Now it is given that 24.5 miles is 65.5% of the distance from Noor’s house to her grandparents’ house.
So, 65.5% of x = 24.5
(65.5*x)/100 = 24.5
65.5*x = 2450
x = 2450 / 65.5
x = 37.40 miles
If rounded off to the nearest tenth mile, we get
x = 40 miles.
So, the distance between Noor's house and her grandparent's house is 37.40 miles or if rounded off to the nearest tenth, it will be 40 miles.

How to find percent sales tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services.
She went shopping for a new pair of sneakers.
The listed price of the pair of sneakers was $43, but the price with tax came to $44.29.
