so 90/360 is da ansa XD ansa
Explanation:
Draw a circle.
Find it's center.
From the center divide the circle into four equal parts, by drawing two diameters , such that angle between two diameter is a right angle.
As, circle is divided into four equal parts, and each part is equivalent to [tex]\frac{1}{4}[/tex].
So, measure of each part in terms of angles in degrees can be found as
[tex]\frac{1}{4}\times 360=90 {\text{degree}}[/tex]
the reason is measure of complete circle is 360 degree.

What is the measure of ∠C?
Answers
The measure of ∠C in the triangle, ΔCDE, in the given figure, is 43°.
A triangle is a geometric figure with three sides, three angles, and three vertices. The sum of all the angles of a triangle is 180°. It is one of the most elementary geometric figures.
As it is known that the sum of all angles of a triangle is 180°,
∠C + ∠D + ∠E = 180°
∠C = 180° - ∠D - ∠E
∠C = 180° - 90° - 47°
∠C = 180° - 137°
∠C = 43°
Thus, the measure of ∠C is 43°.

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Consider the information that the price for a pair of sandals is $49.95 in June.
In August the price is 60% less then;
After getting 60% discount customer need to pay only 40% of the price.
This can be written as:
40% of 49.95
0.40 x 49.95
Therefore, the expression gives the price of the sandals in August would be A 0.40 x 49.95

The height per floor for the Burj al Arab hotel in Dubai is calculated as 17.55 feet, by dividing the total height (1053 feet) by the number of floors (60), but we lack the Aon Center's floor heights to make the comparison as per the question's request.
The student's question is regarding the comparison of floor heights between the Burj al Arab hotel and the Aon Center, a different skyscraper. We need to first calculate the average height of a single floor for each building to compare them. Since the Burj al Arab stands 1053 feet high and has 60 floors, we divide the total height by the number of floors to determine the height per floor.
Total height of Burj al Arab: 1053 feet
Number of floors in Burj al Arab: 60
Height per floor in Burj al Arab: 1053 feet / 60 floors = 17.55 feet
However, the information provided does not include the height of the Aon Center nor its floor count to compare with the Burj al Arab as requested in the question. Additional data is needed to make the comparison. Thus, we are unable to determine how much taller or shorter each floor of the Burj al Arab is compared to the Aon Center's floors with the given information.

The sum of two numbers is 83. If twice the larger number is added to three times the smaller number, the result is 197. Find the numbers.
Answers
solution
let assume the smaller to be y
let assume the larger number to be x
x + y = 83 ------------1
2x + 3y = 197...........2
using simultaneous equation
make x the subject of formular in equation 1
x=83 - y .................3
substitute equation 3 in equation 2
any where you see x replace it with 83-y in equation 2
2(83 - y) + 3y = 197
open the bracket by multiplying by 2 by the content of the bracket
166 - 2y + 3y = 197
-2y +3y = y
therefore:
166 + y = 197
collect like terms by taking 166 to the lefthand side of the equation
y = 197 - 166
y = 31.
substitute y in equation 2 above
x + 31 = 83
collect like terms by taking 31 to the lefthand side of the equation
x = 83 - 31
x = 52
X represent the larger number which is 52
Y represent the lsmaller number which is 31

Show 2 ways that 6 people can share an 8-segment chewy fruit worm
Answers
Final answer:
Two ways to share an 8-segment chewy fruit worm among six people include equal division with some cutting involved for the leftover pieces, or using a trading system based on individual preferences.
Explanation:
There are multiple ways that 6 people can share an 8-segment chewy fruit worm, but let's consider two simple methods. First, we can look at equal division where each person would get 1 segment, and 2 segments are left over. These could then be halved, with six of the people receiving an extra half-segment each, ensuring everyone gets an equal share.
Another method would involve the ideas of trade and preference. Assume each person has different preferences for segments of the worm, similar to the trading scenario of the siblings with Snickers and Milky Ways. Here, they can negotiate and exchange segments based on their tastes, potentially leaving some with more segments but satisfying everyone's preference. This method requires cooperation and may result in an unequal distribution but can lead to each person being happy with their share.

In any given equation, if y=b^x, then logbase(b) of y = x
Due to a property of logarithms, you can also write logbase(b) of y as logy/logb.
The "log" button can be found easily on most modern calculators, so you can follow along too.
Anyways, though, our problem says that 256 = b^4
You can apply logarithms, but an easier way to do this is to square-root 256 twice.
sqrt256->16
sqrt16->4
4^4 is 256. Let's check, shall we?
4*4 is 16. That *4 is 64. 64 *4 is... 256!
Those are just a couple ways to go about it, though.

Robin made a cake with 1/4 pound of butter. She had 7/8 of a pound of butter before she began.
We have to determine the amount of butter have when she was done baking.
As per the given situation, the required solution would be as:
We have to apply the subtraction operation to get it.
Robin used 1/4 pound of butter to make the cake, so she had 7/8 - 1/4 = 15/32 pound of butter left after she finished baking.

for a cub scout meeting, the leader bought 4 pizzas, and 1 1/2 of the pizzas contained pepperoni. the scouts ate 5/6 of the pizzas that contained pepperoni. the remaining pizza that contains pepperoni represents what fraction of the 4 pizzas that the leader bought?
Answers
Answer: Hello there!
We have 4 pizzas, and 1 and 1/2 of them have pepperoni (and 2 and 1/2 do not have pepperoni).
The scouts ate 5/6 of the pizzas that contained pepperoni, this means that they ate 5/6 of the 1 and 1/2 pizza with pepperoni (that can be written as 1 + 1/2 = 3/2)
first we could write the initial fraction of pizza with pepperoni, this is the amount of pizza with pepperoni divided by the total amount of pizza:
(3/2)/4 = 3/8
and now, because the scouts eat 5/6, there is 1/6 left.
then we have (1/6)*(3/8) = 3/48 of the 4 original pizzas, but we could simplify it a bit by dividing both denominator and numerator by 3.
3/48 = 1/16

Answers
Naomi lost fewer than 3 points in a game, implying the integers representing her score could be 0, -1, or -2. Here, -1 and -2 represent she gained points.
Explanation:In a game, Naomi lost points. As stated, she lost fewer than 3 points. Therefore, she could have lost 2, 1, or 0 points. But, as this asks for an integer, we should consider negative numbers as well. Hence, she could have lost -1 or -2 points. In this context, these integers represent she has gained 1 or 2 points. Therefore, use integers such as -2 or -1 to describe Naomi's possible score after she supposedly 'lost' points but actually gained.

Answers
Answer:
option B is correct
The constant of variation for the given quadratic equation is, 0.6
Step-by-step explanation:
The quadratic variation is the relationship between the variables x and y such that : [tex]y=kx^2[/tex]; where k is the quadratic constant variation.
Given quadratic equation are as follow:
[tex]10y = 6x^2[/tex] ...[1]
Division property of equality states that you divide the same number to both sides of an equation
Divide equation [1] both side by 10,we get
[tex]\frac{10y}{10}= \frac{6x^2}{10}[/tex]
On simplifying we get;
[tex]y=\frac{6}{10}x^2[/tex] or
[tex]y= 0.6x^2[/tex]
Now, compare above equation with an equation [tex]y =kx^2[/tex] we get the value of k
i.e, k= 0.6
Therefore, the constant of variation is, 0.6.
