Answer:
=1800g
Step-by-step explanation:
T + S=4050
T + W=2550
let s:w be 3t:t
4050-3t=2550-t
collect like terms
-2t= -1500
-2 -2
t=750g
therefore
T= 2550-750
=1800g

Rafael's chocolate bar is 37% cocoa. If the weight of the chocolate bar is 96 grams, how may grams of cocoa does it contain? Round your answer to the nearest tenth.
You can use the weight of the chocolate bar given and find its 37% to get the weight of cocoa used in it.
The weight of cocoa in the given chocolate bar is 35.52 grams.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
Since weight of cocoa = 37% percent of chocolate bar's weight which is 96 gram,
Thus,
[tex]weight[/tex] [tex]of[/tex] [tex]cocoa=\frac{37}{100}[/tex] × [tex]96=35.52[/tex]Thus,
The weight of cocoa in the given chocolate bar is 35.52 grams.

RelationDomainRangeFunctionVertical Line TestFunction NotationPractical DomainPractical Range===========================================================
Explanation:
A relation is basically anything where we connect one variable to another. Usually there are math operations involved to have a predictable rule. For example, y = x+5 says "add 5 to the x input to get the y output". But we won't always have a rule like this to connect x and y.The domain is the set of allowed inputs (x values). For example, if we had the function y = 1/x, then we can plug in anything but x = 0. This is to avoid a division by zero error.The range is the set of allowed output y values. You can use a graph to determine the range, or find the domain of the inverse (assuming one exists).This is basically saying each input goes to exactly one output only. If such a thing happens, then the relation is a function.A visual way to test if you have a function is to use the vertical line test. If you can pass a vertical line through more than one point, then it is said to have failed the vertical line test and we don't have a function. Failing the vertical line test shows that a particular x value leads to multiple y outputs.Function notation is when we replace y with something like f(x) so the function name is a bit more descriptive.Let's say we had the function f(x) = 100/x. The x represents the number of people, and f(x) is the average cost per person. Before I mentioned that the domain is anything but 0, to avoid a division by zero error. Realistically, we also would make x the set of positive whole numbers (1,2,3,4,...) since x is the number of people. This is one example where a theoretical domain shrinks down to a more practical one. Since the domain shrinks in problem 7, the range is likely to shrink as well. Use a graph or table to see why this happens.A bag contains 4 red balls, 2 green balls, 3 yellow balls, and 5 blue balls. Find each probability for randomly removing balls with

Step-by-step explanation:
The bag has a total of (4+2+3+5) = 14 balls. Set up the proportions:
Red: [tex]\frac{4}{14}[/tex]
green: [tex]\frac{2}{14}[/tex]
yellow: [tex]\frac{3}{14}[/tex]
blue: [tex]\frac{5}{14}[/tex]
Now solve!
Removing 1 yellow, 1 red, 1 green, and 1 blue = [tex]\frac{3}{14} \cdot \frac{4}{14} \cdot \frac{2}{14} \cdot \frac{5}{14} =\frac{15}{4802}[/tex]

Find the length of side a in simplest radical form with a rational denominator.
Answer:
x = 5.5
Step-by-step explanation:
Using a trig ratio, you can use sin, which is opposite over hypotenuse. [tex]sin(30)\textdegree=\frac{x}{11}[/tex]
Now, multiply both sides by 11
[tex]11\cdot sin(30)\textdegree=x[/tex]
this simplifies to x = [tex]\frac{11}{2}[/tex] or 5.5.
Since sin30 is [tex]\frac{\pi}{6}[/tex] radians, it can be written as [tex]\frac{11\pi}{6}[/tex].

What is a histogram?
It is defined as the depiction of numerical data in a graph using a bar with no space. The histogram depicts the approximate distribution of the data.
We have data:
7, 37, 45, 78, 24, 97, 12, 17, 43, 56, 69, 63, 76, 23, 50, 38, 45, 57, 4
We know on the left side skewed histogram has more data on the right and on the left side, there are less data. It is also called a negatively skewed histogram.
On the right side skewed histogram, there is less data on the right side and more data on the left side. It is also called a positive histogram.
Thus, the histogram and stem and leaf plot would be the best choices if you were only concerned about the shape and spread of the data.

Step-by-step explanation:
1.) Move the 5 to the other side of the equation
8y = -5x + 31
2.)
Divide by 8
y= .625x + 3.8
Answer:
5x + 8y = 31
8y = -5x + 31
y = -0,625x + 3,875
y = mx + b
m = slope
b = intercept
y = -0,625x + 3,875
slope = -0,625
