30 g of pineapple are added to drink the drink rises 5 ml what is the density of the pineapple
Answer:
6g/mL
Step-by-step explanation:
Given parameters:
Mass of pineapple = 30g
Volume of rise = 5mL
Unknown:
Density of pineapple = ?
Solution:
Density of a substance is the mass per unit volume. Mathematically, it is expressed as;
Density = [tex]\frac{mass}{volume}[/tex]
The volume is the rise in the pineapple drink.
Insert the parameters and solve;
Density = [tex]\frac{30}{5}[/tex]
Density = 6g/mL

Which inequality represents the graph shown below?
A number line between negative 5 and 5 is shown with an open circle at negative 2 and a ray drawn to the right of negative 2.
A. x –2
D. x ≥ –2
Answer:
x > -2
Step-by-step explanation:
An open circle (unshaded) which starts at -2 and drawn to the right means that the possible values of x do not include -2. Possible values of x are greater than -2, upwards.
Therefore, the inequality to use in representing the information displayed by the graph is x > -2.
This means possible values of x are greater than -2.

Answer:
m = 0
Step-by-step explanation:
To find the slope, use the formula:
m = y2 - y1 / x2 - x1
Then substitute the numbers:
m = 5 - 5 / 6 - 3
m = 0 / 3
m = 0
Therefore, the slope of the line is 0.

If license plates in Idaho have 4 numbers followed by 2 letters, how many different plates can be made?
a. 6,760,000
O b. 676
O c. 260
O d. 17,576,000
The number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters is 6,760,000, option a is correct.
To determine the number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters, we need to consider the possibilities for each element.
For the numbers, we have 10 options (0-9) for each of the four positions, resulting in a total of [tex]10^4 = 10,000[/tex] combinations.
For the letters, we have 26 options (A-Z) for each of the two positions, resulting in a total of [tex]26^2 = 676[/tex] combinations.
To find the total number of different plates, we multiply the number of possibilities for each element:
[tex]10,000 \times 676 = 6,760,000[/tex].
Hence, option a is correct.

Given a polynomial f(x), if (x - 2) is a factor, what else must be true?
f(0) = -2
f(-2) = 0
f(2) = 0
f(0) = 2
show work pls
Answer:
f(2)=0. The third option is correct.
Step-by-step explanation:
Suppose we have a polynomial called f(x) and we know (x-2) is a factor of f. This means that we can express f(x) as:
f(x)=(x-2)\cdot g(x)
Being g(x) another unknown function.
Option 1: f(0)=(0-2)\cdot g(0)=-2\cdot g(0). Since we don't know the value of g(0), we cannot assure f(0)=-2. Incorrect
Option 2: f(-2)=(-2-2)\cdot g(-2)=-4\cdot g(-2). Since we don't know the value of g(-2), we cannot assure f(-2)=0. Incorrect
Option 3: f(2)=(2-2)\cdot g(2)=0\cdot g(0)=0. Regardless of the value of g(0), f(0) must be 0. Correct
Option 4: f(0)=(0-2)\cdot g(0)=-2\cdot g(0). Since we don't know the value of g(0), we cannot assure f(0)=2. Incorrect

Suppose you work in the quality assurance department of a chemical processing plant and it is your responsibility to ascertain whether the viscosity of a certain chemical remains within a prescribed limit. To that end you measure fluid samples using a viscometer. a. The viscosities of a sample of 10 fluids processed during the day shift were measured to have the following results (Pa.s): 71, 45, 54, 75, 50, 49, 63, 55, 48, 50. Determine the range within which the true mean of the fluid samples from the day shift will be with a 95% confidence.
Answer:
48.668 ≤ μ ≤ 63.332
Step-by-step explanation:
Given the data:
Sample (X) : 71, 45, 54, 75, 50, 49, 63, 55, 48, 50
Number of samples (n) = 10
α = 95% = 0.05
Determine the range within which the true mean of the fluid samples from the day shift will be with a 95% confidence
True mean = μ
Confidence interval :
m ± t(α/2 ; df) * s/√n
m - t(α/2 ; df) * s/√n ≤ μ ≤ m + t(α/2 ; df) * s/√n
m = sample mean ; s = sample standard deviation ; df = degree of freedom =(n - 1) = (10 - 1) = 9
Calculating the sample mean and standard deviation using calculator to save computation time :
71, 45, 54, 75, 50, 49, 63, 55, 48, 50
m = 56 ; s = 10.25
m - t(0.05/2 ; 9) * s/√n ≤ μ ≤ m + t(0.05/2 ; df) * s/√n
From t table : t(0.05/2 ; 9) = t(0.025, 9) = 2.262
56-2.262 * (10.25/√10) ≤ μ ≤ 56+2.262 * (10.25/√10)
48.668 ≤ μ ≤ 63.332

Solve for x in the equation.
Answer:
The solution is [tex]\displaystyle x=1\pm \sqrt{47}[/tex]. Fourth option
Explanation:
Solve for x:
[tex]2x^2+3x-7=x^2+5x+39[/tex]
Move all the terms from the right to the left side of the equation, a zero in the right side:
[tex]2x^2+3x-7-x^2-5x-39=0[/tex]
Join all like terms:
[tex]x^2-2x-46=0[/tex]
The general form of the quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
Solve the quadratic equation by using the formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
In our equation: a=1, b=-2, c=-46
Substituting into the formula:
[tex]\displaystyle x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(-46)}}{2(1)}[/tex]
[tex]\displaystyle x=\frac{2\pm \sqrt{4+184}}{2}[/tex]
[tex]\displaystyle x=\frac{2\pm \sqrt{188}}{2}[/tex]
Since 188=4*47
[tex]\displaystyle x=\frac{2\pm \sqrt{4*47}}{2}[/tex]
Take the square root of 4:
[tex]\displaystyle x=\frac{2\pm 2\sqrt{47}}{2}[/tex]
Divide by 2:
[tex]\displaystyle x=1\pm \sqrt{47}[/tex]

Mr. Frankel bought 5 tickets to a puppet show and spent $26. He bought a combination of child tickets for $2 and adult tickets for $10 each. Write a system of equations to determine the number of adult tickets, a, and the number of child tickets, c, he bought. Solve the system. *Show both the equations and solutions
Answer:
3 child tickets and 2 adult tickets
Step-by-step explanation:
5t = 26
2c + 10a = 26
c = 3 a = 2
(2 * 3) + (10 * 2) = 26
6 + 20 = 26
The equations are c + a = 5 and 2c + 10a = 26. Then the number of children and adults will be 2 and 3, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Mr. Frankel bought 5 tickets to a puppet show and spent $26. He bought a combination of child tickets for $2 and adult tickets for $10 each.
Let 'c' be the number of children and 'a' be the number of adults. Then we have
a + c = 5 ...1
2c + 10a = 26 ...2
From equations 1 and 2, then we have
2(5 - a) + 10a = 26
10 - 2a + 10a = 26
8a = 16
a = 2
Then the value of the variable 'c' is calculated as,
2 + c = 5
c = 3
The equations are c + a = 5 and 2c + 10a = 26. Then the number of children and adults will be 2 and 3, respectively.
