Answer:
0.25
Step-by-step explanation:
group like terms: 0.42b+9.14b-8.3=-5.91
add similar elements: 9.56b-8.3=-5.91
multiply both sides by 100: 956b-830=-591
add 830 to both sides: 956b-830+830=-591+830
simplify: 956b=239
divide each side by 956: you know what that looks like
simplify: b=1/4
convert to decimal: 0.25
Answer:
b = 0.25
Step-by-step explanation:
Given:
[tex]\sf 0.42b - 8.3 + 9.14b = -5.91[/tex]
Collect like terms:
[tex]\implies\sf 0.42b+ 9.14b - 8.3 = -5.91[/tex]
Combine like terms:
[tex]\implies \sf 9.56b - 8.3 = -5.91[/tex]
Add 8.3 to both sides:
[tex]\implies \sf 9.56b - 8.3+8.3 = -5.91+8.3[/tex]
[tex]\implies \sf 9.56b=2.39[/tex]
Multiply both sides by 100:
[tex]\implies \sf 9.56b \times 100=2.39 \times 100[/tex]
[tex]\implies \sf 956b=239[/tex]
Divide both sides by 956:
[tex]\implies \sf \dfrac{956b}{956}=\dfrac{239}{956}[/tex]
[tex]\implies \sf b=\dfrac{239}{956}[/tex]
Write 956 as 4 × 239:
[tex]\implies \sf b=\dfrac{1 \times 239}{4 \times 239}[/tex]
Cancel the common factor 239:
[tex]\implies \sf b=\dfrac{1}{4}[/tex]
[tex]\implies \sf b=0.25[/tex]

Factor ab + bc + b 2 + ac.
The factor of the terms ab + bc + b² + ac is ( a + b ) ( b + c ).
Given ab + bc + b² + ac
A factorization is a mathematical object of multiplying several factors usually smaller or simpler objects of the same kind.
To factor the terms we need to write like terms on one side as below
= ab + ac + bc + b²
Separating the common terms as
= a ( b + c ) + b (c + b )
= a ( b + c ) + b ( b + c )
= ( a + b ) ( b + c )

Solving The problem with the help of a linear equation, we can say that the cafeteria had 1.5 gallon of milk at the beginning of the day.
A linear equation refers to an algebraic equation where when the graph plotted with an equation gives a straight line.
First of all we have to assume the amount of the milk is x gallon .
As per the question the amount of sold orange juice is twice as much milk as . So the orange juice was 2x gallon .
They sold 3 gallon of orange juice .
∵ we can generate an equation,

The point C(4,5) is rotated 270° counterclockwise around the origin. What are the coordinates of the resulting point, C'?
The coordinates of the resulting point C' are (-5, 4).
What are coordinates?A coordinate system in geometry is a system that uses one or more numbers, or coordinates, to determine the position of points or other geometric elements on a manifold, such as Euclidean space. The order of the coordinates matters, and they are sometimes identified by their position in an ordered tuple and other times by a letter, as in "the x-coordinate."Since we know that rotating a point 270° counterclockwise about the origin causes the point (x,y) to become (-y, x), we can swap the positions of the x and y coordinates and make y negative.
We have, using the above transformation:
(x, y) ⇒ (-y, x)(4, 5) ⇒ (-5, 4)Therefore, the coordinates of the resulting point C' are (-5, 4).

Find the distance between the points (-10, -2) and (-8,0).
*round to the nearest tenth
The distance between the given pair of points (-10, -2), (-8,0 ) round to the nearest tenth is 2.8.
What is the distance between the given pair of points?The distance formula used in finding the distance between two points is expressed as;
D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )
Given the data in the question;
Point 1(-10, -2)
x₁ = -10y₁ = -1Point 2( -8,0 )
x₂ = -8y₂ = 0Plug the given values into the distance formula and simplify.
D = √( ( x₂ - x₁ )² + ( y₂ - y₁ )² )
D = √( ( (-8) - (-10) )² + ( 0 - (-2) )² )
D = √( ( -8 + 10 )² + ( 0 + 2 )² )
D = √( ( 2 )² + ( 2 )² )
D = √( 4 + 4 )
D = √8
D = 2.8
Therefore, the distance between the given pair of points (-10, -2), (-8,0 ) round to the nearest tenth is 2.8.

B. 1/4 + 3/4 + 1/3 = 1 + 1/3 = 1 1/3
C. ( 1/4 + 1/3 ) + 3/4 = 7/12 + 9/12 = 16/12 =1 1/3
D. 1/12 (3+ 4+ 9) = 1/12(16) = 16/12 = 1 1/3
Answer:
B is the correct use of the commutative property.
Step-by-step explanation:
Let's use the process of elimination.
We can see that A is not using the commutative property because the sum of the numbers in the parentheses are just being combined.
C doesn't work because they just added 1/3 and 3/4, which doesn't work.
And finally D doesn't work because they used the distributive property instead.
B works because they combined 1/4 and 3/4 to equal 1, an easy number to calculate, and added 1/3 to get a final answer is 1 1/3.
So B is the answer.

Based on the calculations, table B shows a rate that is greater than 1 kilometer per hour.
What is the average rate of change?The average rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.
Mathematically, the average rate of change can be calculated by using this formula;
Average rate of change = Δy/Δx = Change in kilometer/Change in hour
For table A, we have:
Rate = kilometer/hour
Rate = (1/5)/(7/5)
Rate = 1/5 × 5/7
Rate = 1/7 kilometer per hour.
For table B, we have:
Rate = (3/4)/(3/8)
Rate = 3/4 × 8/3
Rate = 2 kilometer per hour.
For table C, we have:
Rate = (2/3)/(4/3)
Rate = 2/3 × 3/4
Rate = 1/2 kilometer per hour.
For table C, we have:
Rate = (2/3)/(4/3)
Rate = 2/3 × 3/4
Rate = 1/2 kilometer per hour.
For table D, we have:
Rate = (1/4)/(3/4)
Rate = 1/4 × 4/3
Rate = 1/3 kilometer per hour.
Therefore, table B shows a rate greater than 1 kilometer per hour.

What is defined as the ratio?A ratio in mathematics is a comparable of two or more numbers that shows their sizes in regards to each other. A ratio compares two quantities by dividing them, with the dividend or number divided referred to as the antecedent as well as the divisor or number divided referred to as the consequent.A ratio can be expressed as a part-to-part or part-to-whole comparison.Now, as per the given question;
Part a: The value of 'n'.
The ratio 20 minutes to 1 hour can be written in the form 1: n.
20 minutes/1 hour = 1/n
We know that; 1 hour = 60 minutes.

Cross multiplying;
20n = 60
n = 60/20
n = 3
The value of n is found to be 3.
Part b: kilometres on the ground.

1 cm on map = 25,000 km on grounds.
Thus, for 9 cm om map.
Multiplying both side of ratio with 9.

Choice C) The function is positive over the interval (3,∞).
Choice D) The function is positive over the interval (−∞,−5).
====================================================
Explanation:
The portion below the x axis is when f(x) is negative. This happens on the interval -5 < x < 3−5<x<3 . Note how -5 and 3 are the x intercepts or roots. So because f(x) is negative when -5 < x < 3−5<x<3 we can say f(x) is negative over the interval (-5, 3). This is interval notation and not ordered pair notation.
----------
The function f(x) is positive in two places. When x < -5 and when x > 3. This is where the purple parabola is above the x axis.
The x < -5 portion converts to the interval notation (−∞,−5)
The x > 3 portion converts to the interval notation (3,∞)
