In a certain chemical, the ratio of zinc to copper is 4 to 19 . A jar of the chemical contains of copper. How many 741 grams of zinc does it contain?
Answers
Based on the ratio of zinc to copper, and the grams of copper in the jar, the grams of zinc will be 156 grams of Zinc
How to find the grams?The ratio of zinc to copper is 4 to 19 which means that for every 4 grams of Zinc, the chemical will have 19 grams of copper.
The means that if there is 741 grams of copper, the grams of Zinc will be:
= (Grams of Copper x Ratio of Zinc) / Ratio of copper
Solving gives:
= (741 x 4) / 19
= 2,964 / 19
= 156 grams of Zinc

An amusement park charges $32 for admission and $6 to park your car. Write an inequality that represents the possible number of people that could go for $166. Solve the inequality. What is the maximum number of people that could go?
Answers
The maximum number of people that could go will be 5.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
For the inequality, we have to apply the arithmetic operation in which we do the multiplication of x and apply the inequality for the given data.
It is given that,
An amusement park charges $32 for admission and $6 to park your car.
To ascertain the maximum or lowest values of a scenario with many restrictions, a system of linear inequalities is frequently utilized. Inequalities reflect a limit of what is permitted or achievable rather than a precise quantity.
Suppose that everyone is going in one car and x is the number of persons in the car. The inequality represents the possible number of people that could go for $166 is,
32x+6≤166
32x≤160
x≤160/32
x≤5
Thus, the maximum number of people that could go will be 5.

Answer:
40% of the jerseys are medium-sized
Step-by-step explanation:
Total = 50 jerseys
20 medium-sized
50 x 2 = 100

Answers
The answer will be f(x) = 5*. If f′(x)>0 on an open interval, then f is increasing on the interval and If f′(x)<0 on an open interval, then f is decreasing on the interval.
Which function is making f X larger?For a given function, y = F(x), the function is known as an increasing function if the value of y increases as the value of x increases, and the function is known as a decreasing function if the value of y decreases as the value of x increases.The order of the numbers is said to be growing if they are written from smallest to largest, but decreasing order is used when the numbers are written from largest to smallest.You must first compute the derivative, then make it equal to 0, and then determine which zero values the function is negative between in order to determine whether a function is decreasing. In order to determine when the function is negative and, consequently, decreasing, test values on all sides of these.Hence, The answer will be f(x) = 5*. If f′(x)>0 on an open interval, then f is increasing on the interval and If f′(x)<0 on an open interval, then f is decreasing on the interval.

80% of a number is equal to two-thirds of a second number.
The whole number ratio of the first number to the second number in its lowest terms is x:y
What is the value of x−y
?
Answers
Answer:
-1
Step-by-step explanation:
Let's assume 100 as the number. 80% of that number is 80. That's A. And since 80 is two-thirds of that number, the second number has to be 120. Simplifying that would give 5/6. 5-6 = -1
Answer: 1:1.2
1-1.2= -0.2
Step-by-step explanation:
x = first number
y = second number
80/100*x (80 percent of one number)
2/3*y (two thirds of the second number)
equating
80/100*x=2/3*y
= 1.2=y
substituting:
80/100*x = 2/3 * 1.2
= x=1
substituting the value of x in the original equation
80/100 * 1 = 2/3 * y
= y=1.2
so, x=1, y=1.2
x:y
=1:1.2
x-y= 1 - 1.2 = -0.2
What is the slope of y = −x+7?
Answers
A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Explain about the slope?The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. B is the b in the location where the y-intercept is located (0, b). For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.
A line's slope often indicates the steepness and direction of the line. By calculating the difference between the coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them. The letter "m" is frequently used to denote slope.
where m is the slope and y=mx+b
You can also write y =-x+7 as y=-1x +7.
Therefore, the slope is determined by the number before x.
The slope is -1

How does a proportionate relationship work?Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.If a table displays a proportional relationship, the ratio of each pair of values can be determined. The table depicts a proportionate relationship if all of those ratios are the same.The equation y = kx represents a proportionate relationship between two quantities y and x that have the same proportionality constant, k.A linear relationship between two amounts or variables is referred to as proportionality in mathematics.

The value of k after eliminating the fraction in 3/5k -5 = 7/10k is 7.
To get the answer follow the given steps below:
3 / 5 k - 5 = 7 / 10 k
Step 1 => 3 (10 k) = 7 (5 k - 5) by cross multiplying the numerator and denominator of both the sides.
Step 2 => 30 k = 35 k - 35 multiplying 5 inside the brackets with 5k - 5
Step 3 => 35 = 5 k
Step 4 => 5 k = 35

Let P be a polynomial function, and P(x)=x4−dx3+8x2−14x+16. If (x−2) is a factor of the polynomial, what is the value of d? Explain or show how you know.
Answers
The value of d is x - 2 is a factor of the polynomial function P(x) is 4.5
How to calculate the value of d?The polynomial function is given as
P(x) = x⁴ − dx³ + 8x² −14x + 16
Also, we have the factor of the polynomial to be
x - 2
Set the factor to 0
So, we have
x - 2 = 0
Solve for x
x = 2
If truly, the variable x - 2 is a factor of the polynomial, then the following must be true
P(2) = 0
Start by substituting 2 for x in the equation P(x) = x⁴ − dx³ + 8x² −14x + 16
So, we have
P(2) = (2)⁴ − d(2)³ + 8(2)² −14(2) + 16
Evaluate the exponents
P(2) = (16) − d(8) + 8(4) −14(2) + 16
Evaluate the sum of products
P(2) = −8d + 36
Set to 0
−8d + 36 = 0
So, we have
−8d = - 36
Divide
d = 4.5
Hence, the value of d is 4.5

The expression rewrites the total 32 + 80 using the largest common factor and the distributive property, and the expression can be expressed as 16(2 + 5).
Option (c) is correct.
The least common multiple of two integers is defined as the lowest number that is a multiple of two or more numbers. The abbreviation LCM stands for least common multiple.
It is assumed that:
The mathematical formula is:
= 32 + 80
To identify the most prevalent factor:
GCF( 32, 80) ( 32, 80) ( 32, 80)
We can use Euclid's division lemma to find the GCF:
GCF(32,80)= 16
The phrase 32 + 80 can be expressed as follows:
= 32 + 80\s= 16(2 + 5)
As a result, the equation rewrites the total 32 + 80 using the largest common component and the distributive condition, and the expression can be expressed as 16(2 + 5).
