Montserrat can make 4 bracelets in 2 1/4 hours. How many bracelets can she make per hour
Answer: Montserrat bracelets can she make per hour = 0.5625 hours
Step-by-step explanation:
Given data,
Montserrat can make 4 bracelets in 2 1/4 hours.
Let assume Montserrat can make 1 bracelets in x hours.
So,
we can write,
4 ⇒ 2 1/4
1 ⇒ x
Then,
4x = 1 * 2 1/4
4x =1* 9/4
4x = 9/4
x = (9/4)/4
x = 9/16
x = 0.5625 hours.

The relationship between area and cost is 3/4 means 4 times area gets 3 times cost.
Given the cost to rent an apartment is proportional to the number of square feet in the apartment.
Given the cost of an 800 sqft apartment per month = 600$
By using the given information we can define the relationship between area and cost as below
For 800 sqft = 600 $
for 1 sqft = x
It can be written as
800/1 = 600/x
By cross multiplicating the terms on both sides we get

a contractor buys 8.2 square feet of sheet metal. she used 2.1 square feet so far and has $183 worth of sheet metal remaining. write and solve an equation to find out how much sheet metal costs per foot
1) The equation that shows the cost of sheet metal per foot, s/ft² = $183 ÷ 6.1 ft².
2) The solution of the equation shows that sheet metal costs $30 per foot.
What is an equation?An equation is a mathematical expression that states that two variables are equal.
Equations are stated using the equation symbol (=).
Data and Calculations:The total quantity of sheet metal bought = 8.2 ft²
The total quantity of sheet metal used = 2.1 ft²
The remaining quantity of sheet metal = 6.1 ft² (8.2 ft² - 2.1 ft²)
The value of the remaining quantity of sheet metal = $183
The cost of sheet metal per foot = $30 ($183/6.1 ft²) or ($183 ÷ 6.1 ft²)

Hayley and Phoebe have a lemonade stand where they sell cups of lemonade for $0.75 a piece. The function p(c)=0.75c represents the profit p(c) that the girls
earn if they sell c cups of lemonade. The girls have 150 cups.
Find the domain and range. Write your answers as compound inequalities.
The domain of the function is given by: 0 ≤ c ≤ 150
The range of the function is given by : 0 ≤ p(c) ≤ 112.5
The range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of domain values.In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).The given statement states that the profit from selling 150 cups of lemonade is denoted by p(c) such that p(c) = 0.75c
Now the girls can sell a maximum of 150 lemonades.
Hence the domain of the values are : 0 ≤ c ≤ 150
at x=0 , p(c) = 0.75 × 0 = 0
at x= 150 , p(c) = 0.75 × 150 = 112.50
Therefore the range of the function is : 0 ≤ p(c) ≤ 112.5

x=8x-28
-8x from each side.
-7x=-28
divide both sides by -7
X=4
Answer: x=4
1. Multiply both sides by 4 to get rid of the denominator, which gives you x-8 = 8x-36
2. Subtract 8x from both sides, which gives you x - 8 - 8x= -36
3. Add 8 to both sides, which gives you x - 8x = -36 + 8

Write log 150 as a sum or difference of two logarithms. Simplify if possible.
log 150 = log 50 + log 3
∴ log 150 = 2.176
As the base is not mentioned, we will take the base as 10. We will apply the product rule of logarithms to this equation.
log (150) can also be written as log (50×3).
Therefore, log (150) = log 50 + log 3
We know, log 3 = 0.477log 150 = log 50 + 0.477
Now, we can write log 50 as log (100/2). We will use the quotient rule of logarithms.log 50 = log 100 - log 2
We know, log 100 = 2 and log 2 = 0.301∴ log 50 = 2 - 0.301
log 50 = 1.699 Substituting the value of log 50 = 1.699 in the main equation, log 150 = log 50 + log 3log 150 = 1.699 + 0.477log 150 = 2.176

The actual area of the bedroom is bigger than the actual area of the kitchen.
The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The area of a rectangle is determined by its dimensions. A rectangle's area is essentially equal to the product of its length and breadth.
In the drawing, the kitchen is in the shape of a rectangle with dimensions of 12 cm × 27 cm.
Therefore, the area of the rectangle will be:
Area = Length × Breadth
Area = 12 cm × 27 cm
Area = 324 cm²
Now, the actual area of the bedroom is 300,000 cm².
Then the difference between the area,
difference = bedroom - kitchen

Terry was measuring the volume of water on a graduated cylinder but did not notice that the measurements incremented by 2 instead of by 1. As a result he misread the volume of the liquid as 33.0 instead of 36.0. What is his percent error?
We conclude that the percent error in Terry's reading is 8.3 percent.
How to find the percent error?If you did a reading on a value V, and your reading is another value V', the percent error in your reading is given by the formula:
P = 100%*|V - V'|/V
In this case, Terry's reading of the volume of the liquid is V' = 33.0, while the actual value is V = 36.0
Replacing that in the formula for the percent error we get:
P = 100%*|36.0 - 33.0|/36.0 = (3.0/36.0)*100% = 8.3%

11- 1/2y = 3 + 6x solve for y (literal equation) I'm very confused is it y = 3 + 6x - 11 ×(-2)?
====================================================
Explanation:
Multiply both sides by 2 to clear out the fraction
11 - (1/2)y = 3 + 6x
2* ( 11 - (1/2)y ) = 2*(3 + 6x)
2*11 - 2*(1/2)y = 2*3 + 2*6
22 - y = 6 + 12x
Then let's solve for y
22 - y = 6 + 12x
-y = 6 + 12x-22
-y = 12x-16
y = -(12x-16)
y = -12x+16 is the answer
The final answer is in slope intercept form y = mx+b
m = -12 = slope
b = 16 = y intercept

Which represents our equation.
How to get a table for the given relation?We want to get a table of the form:
x: x₁, x₂, x₃, ...
y: y₁, y₂, y₃, ...
To get that, we need to evaluate the given equation in some different values of x, so let's do that.
if we take x = 0, then we get:
y = -(4/7)*0 - 2 = -2
So we have the pair (0, -2)
If x = 7, then:
y = (-4/7)*7 - 2 = -4 - 2 = -6
So we have the pair (7, -6)
If x = -7 then:
y = (-4/7)*-7 - 2 = 4 - 2 = 2
So we have the pair (-7, 2)
So now that we have 3 pairs we can write the table:

A function's inverse is a function that reverses the action of a function, say [tex]f[/tex]. If the inverse of f exists, it is denoted by f ⁻¹ and exists only if f is a bijective function.
The domain of a relation's inverse corresponds to the original relation's range. In other words, the inverse's x values are the relation's y values.
Consider the function,
f(x) = y = 2x² - 8
Swapping x and y, to find the inverse.
x = 2y² - 8
Adding 8 on both sides of the equation.
x + 8 = 2y² - 8 + 8

Graph the inequality. z is less than or equal to 5
Normal curve g has a mean of 50 and a standard deviation of 5. Normal curve h has a mean of 50 and a standard deviation of 10. How do the shapes of these two normal curves compare if they are drawn using the same scale?.
Drawn using the same scale, the shape of the normal curve H will be more spread out than the shape of the normal curve G.
Normal curve, or Gaussian distribution, is a curve that describes data form a variable that has infinite, or very large, number of possible values distributed among the population. It has a symmetric shape, and the distribution rises in the middle, and goes down to the left and to the right. The mean is equal to the mode and median and is located at the middle or top of the curve.
If two normal curves have the same mean, but different standard deviations, then the curve with the larger standard deviation will have a more spread out shape than the other.
If Normal curve H has a standard deviation of 10 and normal curve G has 5, but both has the same mean, then Normal curve H has a more spread out shape than the curve of normal curve G.

If AABC AFDE, which of the following statements is true? O ZA ZE O
If ∆ABC and ∆FDE are congruent, then the correct statement among options is ∠C ≅ ∠E.
Congruent figures refers to the figures that can be superimposed on each other. This states that the angles and sides are similar for both the figures being compared. We are given that two triangles are congruent. Same will be true for their sides as well.
Thus, we can interpret that similar angles in the mentioned two triangles will be -
∠A ≅ ∠F
∠B ≅ ∠D
∠C ≅ ∠E
Similarly, the similar sides for both triangles will be -
AB ≅ FD
BC ≅ DE
AC ≅ FE
Therefore, in the congruent triangles ABC and FDE, ∠C and ∠E are congruent.
