Answer:
37 is your answer
Step-by-step explanation:
let "a number" = x
"twelve subtracted from [x]" = x - 12
"equals 25" = = 25
Set the equation
x - 12 = 25
Isolate the variable. Note the equal sign, what you do to one side, you do to the other. Add 12 to both sides
x - 12 (+12) = 25 (+12)
x = 25 + 12
x = 37
37 is your answer
~
The question is asking for a number that results in 25 when 12 is subtracted from it. This is an algebraic expression represented as x - 12 = 25. The solution is x = 37.
Explanation:The question is asking to find a number when 12 is subtracted from it; the result is equals to 25. This is a basic algebraic expression where we let the unknown number be represented by the letter 'x'.
So, we can rewrite the question as an equation: x - 12 = 25.
To find 'x', we need to isolate it on one side of the equation, and to do so, we add 12 to both sides of the equation. This gives us: x = 25 + 12.
Adding 25 and 12, we get 37. So, the number you're looking for is 37.

A recipe for beef stew requires 1 and 3/4th pounds of meat.You are making 6 and 1/2 batches of the recipe. how much meat do you need?
Answer:
11.375 pounds
Step-by-step explanation:
1.75 * 6.5 = 11.375
11 and 3/8 pounds of meat are required in total.
The student is asking a multiplication problem that involves fractions. To find the amount of meat needed, we multiply the amount of meat required for one batch by the number of batches.
Step-by-Step Calculation
First, we must convert the fractions into improper fractions to simplify calculation. The recipe requires 1 and 3/4 pounds of meat, which is
7/4 pounds (since 1 pound is 4/4 pounds, we add 3/4 pounds to get 7/4 pounds).
Next, the number of batches is 6 and 1/2, which as an improper fraction is 13/2 batches.
To find the total amount of meat required, we multiply the pounds per batch by the number of batches: (7/4) pounds x (13/2) batches = (7/4) x (13/2) = (7 x 13) / (4 x 2) = 91/8 pounds.
Finally, convert 91/8 pounds to a mixed number: 11 and 3/8 pounds of meat are required in total.

[tex]\frac{x^2+4x-1}{x\left(x+2\right)}[/tex] or
[tex]\frac{x^2+4x-1}{x^2+2x}[/tex]
Step-by-step explanation:
Given expression is:
[tex]\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{\left(x^2+2x\right)}[/tex]
We begin by factoring denominators:
[tex]=\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}[/tex]
Multiply and divide first term by (x) to make denominators equal.
[tex]=\frac{x\left(x+5\right)}{x\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}[/tex]
Since denominators are equal so we can combine numerators.
[tex]=\frac{x\left(x+5\right)-\left(x+1\right)}{x\left(x+2\right)}[/tex]
Now simplify
[tex]=\frac{x^2+5x-x-1}{x\left(x+2\right)}[/tex]
[tex]=\frac{x^2+4x-1}{x\left(x+2\right)}[/tex]
[tex]=\frac{x^2+4x-1}{x^2+2x}[/tex]

Shelly bought a 2-ounce tube of blue paint. She used 2/3 Ounce to paint the water,3/5 once to paint the sky and some to paint a flag. After that she has 2/15 ounce left.How much paint did Shelby used to paint her flag?(PlS ANSWER)
Answer:
I think what you should do is 2/3 + 3/5 and then sutract it from the 2-ounce tube or you can do 2/15 - 2-ounces.
Step-by-step explanation:
Shelby used [tex]\frac{9}{15}[/tex] or [tex]\frac{3}{5}[/tex] ounce to paint the flag.
She bought 2-ounce tube of blue paintShe used [tex]\frac{2}{3}[/tex] ounce to paint the waterShe used [tex]\frac{3}{5}[/tex] ounce to paint the skyShe had [tex]\frac{2}{15}[/tex] ounce leftThe ounce used to paint a flag is unknownFurther ExplanationTo determine how much paint Shelby used to paint her flag then, we have:
= [tex]\frac{2}{3}[/tex] + [tex]\frac{3}{5}[/tex] + [tex]\frac{2}{15}[/tex] (let solve the first 2 fractions)
= [tex]\frac{2}{3}[/tex] + [tex]\frac{3}{5}[/tex] (the lowest common denominator of 3 and 5 is 15)
= (5 x 2) + (3 x 3) / 15
= (10) + (9) / 15
= 10 + 9 / 15
= [tex]\frac{19}{15}[/tex] .
Now we should add [tex]\frac{9}{15}[/tex] with the fraction of ounce she had left: [tex]\frac{2}{15}[/tex]
Therefore, we have
= [tex]\frac{19}{15}[/tex] + [tex]\frac{2}{15}[/tex] (the lowest denominator of 15 and 15 is 15)
= (19 x 1) + (1 x 2) / 15
= (19) + (2) / 15
= [tex]\frac{21}{15}[/tex] .
Recall that the total paint is 2-ounce. Therefore, to get the fraction of ounce used to paint a flag, we have to subtract the ounce of the total paint from the [tex]\frac{21}{15}[/tex] .
Therefore we have:
2-[tex]\frac{21}{15}[/tex] (can also be expressed as [tex]\frac{2}{1}[/tex] – [tex]\frac{21}{15}[/tex] )
= (15 x 2) – (1 x 21) / 15 (the lowest denominator is 15)
= (30) – (21) / 15
= 30 – 21 / 15
= [tex]\frac{9}{15}[/tex] or [tex]\frac{3}{15}[/tex] .
Therefore Shelby used [tex]\frac{9}{15}[/tex] or [tex]\frac{3}{5}[/tex] ounce to paint the flag.

Step-by-step explanation:
We have been given an equation y+6=45(x+3) in point slope form.
It says to use the point and slope from given equation to create the graph.
So compare equation y+6=45(x+3) with point slope formula
y-y1=m(x-x1)
we see that m=45, x1=-3 and y1=-6
Hence first point is at (-3,-6)
slope m=45 is positive so to find another point, previous point will move 45 units up then 1 unit right and reach at the location (-2,39).
Now we just graph both points (-3,-6) and (-2,39) and join them by a straight line. Final graph will look like the attached graph.

If you apply the changes below to the linear parent function, F(x)=x, what is the equation of the new function? vertically compress by 1/4 flip over the y-axis
Final answer:
The new function after applying the given transformations to the linear parent function f(x) = x, results in f(x) = -1/4x, representing a combined vertical compression and reflection about the y-axis.
Explanation:
Starting with the linear parent function f(x) = x, we need to apply two transformations: a vertical compression by 1/4 and then a reflection over the y-axis. Applying a vertical compression by 1/4 means we multiply the output by 1/4, resulting in f(x) = (1/4)x.
To reflect the function across the y-axis, we replace x with -x, which gives us the new function f(x) = (1/4)(-x) or, simplified, f(x) = -1/4x. Therefore, the equation of the transformed function is f(x) = -1/4x.
Cube A has a volume of 125 cubic inches. The edge lengths of cube B measure 4.8 inches. Which cube is larger and why?
Answer: Cube A is larger. This is because volume is found by multiplying length × width × height. The length, width, and height of a cube are ALWAYS equal. Therefore if cube B has a length of 4.8 inches it also has a height of 4.8 inches and a width of 4.8 inches. To find its volume multiply 4.8×4.8×4.8 this will give you 110.592 cubic inches. This means cube A is larger.
Cube A is bigger because of bigger volume.
Given that;Volume of cube A = 125 cubic inches
Side of cube B = 4.8 inches
Find:Which cube is big
Computation:Volume of cube = Side³
Volume of cube B = 4.8³
Volume of cube B = 110.592 cubic inches

A f and g intersect at -2
B f and g intersect a x=2
C f and g intersect the x-axis at -2
D f and g intersect the y-axis at -2
If choice A says the two functions intersect at x = -2, then it would be the correct answer. Though it seems the "x=" part is left off. I'm not sure if this is intentional, or a typo.
The correct option is A) f and g intersect at x = -2

Given :
x = -2 is a solution to the equation f(x) = g(x).
Solution :
x = -2 must be an intersection point of the equations f(x) and g(x) because
f(x) = g(x). And the point x = -2 satisfy both the equations.
Therefore, the correct option is A) f and g intersect at x = -2.

Measurement of angle 1
Answer:
55 degrees
Step-by-step explanation:
Given that a circle and inside two chords with same arc length.
We are to find the angle between the two chords.
Given that two arcs subtend angle 125 degrees at the centre.
Let us join the two ends of chords to make the figure as a triangle inside a circle.
The triangle is isosceles as two arcs and hence chords are equal.
By central angle theorem we have the two equal angles as 1/2 (125) = 62.5
Hence we have a triangle with two equal angles 62.5 and another angle 1.
By triangle sum of angles theorem
angle 1+62.5+62.5 = 180
Hence angle A = 180-62.5-62.5 = 55 degrees.

A brick measures 30 cm × 10 cm × 7 1/2. How many bricks will be required for a wall 30 m long. 2 m high and 3/4 m thick?
Given the dimensions of the brick, we first calculated its volume in cubic meters. Then we calculated the volume of the wall in cubic meters. Dividing the volume of the wall by the volume of a single brick, we find that we need 20,000 bricks to build the wall.
Explanation:This is a problem in Mathematics, specifically involving volume and unit conversion. The volume of the brick can be calculated using the formula for the volume of a rectangular prism, Volume = length x width x height. The dimensions given for the brick are in centimeters and the wall dimensions are given in meters. Therefore, we must convert the brick dimensions to meters: 30 cm = 0.3 m, 10 cm = 0.1 m and 7.5 cm = 0.075 m. The volume of one brick is 0.3 m * 0.1 m * 0.075 m = 0.00225 cubic meters.
The volume of the wall is also given by the formula length x width x height, so it is 30 m * 2 m * 0.75 m = 45 cubic meters. To find the number of bricks required to fill this volume, divide the volume of the wall by the volume of a single brick, 45 m³ / 0.00225 m³ = 20000 bricks. Thus, it will take 20,000 bricks to build the wall.

“The true mean weight of the piglets is at most 39lbs”would be the alternate hypothesis.
Step-by-step explanation:
Given that the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”
We have to find the alternate hypothesis.
In hypothesis testing, alternate is the opposite of null hypothesis. If null hypothesis supports one statement alternate hypothesis opposes it. In other words, alternate hypothesis would be the negative of the claim of null hypothesis.

It takes 10 people 5 days to complete a piece of work at a factory when working 2 hours a day. Working at the same pace, how many days will it take 2 people to do the same work, if they are working 5 hours a day?
Answer:
It will take 2 people 10 days to complete the task.
Step-by-step explanation:
It takes 10 people 5 days to complete a piece of work at a factory when working 2 hours a day, i.e., 10 people take 10 working hours to complete a task.
When number of people is decreased by 5 times, i.e., 10÷5=2, then the amount of working hours are increased by 5, i.e., 10×5= 50 hours.
If the 2 workers work 5 hours per day then they will require 10 days to complete the task of 50 hours.
