The fraction models below represent two fractions of the same whole. How much of the Fraction 5 over 8 is in the Fraction 1 over 2?
Two rectangles of the same size are drawn side by side touching each other. The first rectangle is divided into 8 portions of equal size. Five of these are shaded. The shaded portion alone is labeled as 5 over 8. The second rectangle is divided into 2 portions of equal size. One portion is shaded. The shaded portion alone is labeled 1 over 2.
Fraction 5 over 16
Fraction 4 over 5
Fraction 5 over 4
Fraction 16 over 5
To find how much of 5/8 is you would need to divide 1/2 by 5/8:
X = (1/2) / (5/8)
When dividing fractions, you reverse the second fraction and multiply:
X = (1/2) x (8/5)
X = 8/10
Simplify:
X = 4/5
The fractional amount of the fraction 5 over 8 in the fraction 1 over 2 is the fraction 4 over 5. Therefore, Option B is correct.
From the information given;
We are to find how much the Fraction 5 over 8 is in the Fraction 1 over 2
This implies that we need to divide the fraction 5 over 8 i.e. [tex]\mathbf{\dfrac{5}{8}}[/tex] by the fraction 1 over 2 i.e. [tex]\mathbf{\dfrac{1}{2}}[/tex]
Mathematically;
[tex]\dfrac{1}{2} \div \dfrac{5}{8}[/tex]
[tex]\mathbf{= \dfrac{1}{2} \times \dfrac{8}{5} }[/tex]
[tex]\mathbf{= \dfrac{4}{5}}[/tex]
Therefore, we can conclude that the fractional amount of the fraction 5 over 8 in the fraction 1 over 2 is the fraction 4 over 5.

20. A computer programmer works 40 hours per week. What is an equation that
relates the number of weeks w that the programmer works and the number of
hours h that the programmer spends working?
The equation to relate the number of weeks a computer programmer works to the number of hours worked is h = 40w, where h represents the total hours worked and w represents the number of weeks.
To relate the number of weeks w that a computer programmer works to the number of hours h he or she spends working, we can use a simple multiplication equation. Since we know the programmer works 40 hours per week, the relationship between hours worked and number of weeks can be represented as:
h = 40w
This equation states that the total hours worked (h) is equal to 40 times the number of weeks worked (w). For example, if the programmer works for 2 weeks, the total hours worked would be h = 40 * 2, which equals 80 hours.

A bedroom is 11.4 feet long amd 12.5 feet wide. Shui wants to paint the floor. A gallon of paint will cober approximately 150 square feet. Will one gallon of paint be enough to paint the bedroom floor with 2 coats of paint? Explain your reasoning
Answer:
One gallon of paint is not enough to paint the bedroom floor
Step-by-step explanation:
step 1
Find the area of the bedroom floor
The area is in the shape of rectangle
so
[tex]A=(11.4)(12.5)=142.5\ ft^2[/tex]
Remember that the bedroom floor will be painted with two coats of paint
so
Multiply the area by two
[tex]A=(2)142.5=285\ ft^2[/tex]
A gallon of paint will cover approximately 150 square feet
[tex]285\ ft^2 > 150\ ft^2[/tex]
therefore
One gallon of paint is not enough to paint the bedroom floor
Final answer:
No, one gallon of paint will not be enough to paint the bedroom floor with 2 coats of paint.
Explanation:
To determine if one gallon of paint will be enough to paint the bedroom floor with 2 coats of paint, we need to calculate the total area of the floor and then divide it by the coverage area of a gallon of paint.
The area of the bedroom floor is calculated by multiplying the length and width together: 11.4 feet * 12.5 feet = 142.5 square feet.
Since we need to apply 2 coats of paint, we need to double the area: 142.5 square feet * 2 = 285 square feet.
Since one gallon of paint covers approximately 150 square feet, one gallon of paint will not be enough to paint the bedroom floor with 2 coats of paint.

11. Isaac wrote two simplified expressions that were not equal to each other. Each equation also had
a different coefficient on the variable. If he sets the expressions equal to each other, will the
equation have one solution, no solution or infinitely many solutions? Use an example to support
your answer.
Answer:
The equation has only one solution
Step-by-step explanation:
* Lets explain how to solve the problem
- There are three types of solutions for the equations
Case (1)
# Two sides of the equation have different coefficient of the variable
and same or different numerical terms, then the equation has only
one solution
- Ex: 2x + 5 = x + 5, lets solve it
∵ 2x + 5 = x + 5
- subtract x from both sides
∴ x + 5 = 5
- Subtract 5 from both sides
∴ x = 0
- Zero is a solution
∴ The solution of the equation is x = 0
- If the numerical terms are different x will be any other value, so the
equation has only one solution
∴ The equation has one solution
Case (2)
# Two sides of the equation have same coefficient of the variable,
and different numerical terms, then the equation has no solution
- Ex: 14x - 20 = 14x + 10, lets solve it
∵ 14x - 20 = 14x + 10
- Subtract 14x from both sides
∴ - 20 = 10
- The left hand side not equal the right hand side , then there is
no value of x can make the two sides equal
∴ The equation has no solution
Case (3)
# Two sides of the equation have same coefficient of the variable,
and same numerical terms, then the equation has infinitely
many solutions
- Ex: 3x + 5 = 3x + 5, lets solve it
∵ 3x + 5 = 3x + 5
- Subtract 3x from both sides
∴ 5 = 5
- The left hand side is equal to the right hand side , then x can be
any value because the two sides is already equal without x
∴ The equation has infinitely many solutions
∵ He will write two expressions simplified , not equal , have different
coefficients on the variables and equate them, then it is like
the first case
- That means not same coefficient of the variable, and may be not
same numerical term
∴ The equation has only one solution
which even number is a prime number

How do I solve the expression -4d+3 d if =-1
Answer:The answer would be -1
Step-by-step explanation:
First insert the -1 into the equation which would look like this -4(-1)+3 which is then multiplication which would narrow the solution down to -4+3 which a negative plus a positive is a rule called you always subtract and the number with the bigger value determines what sign you use so in this equation it would be 4 since 4 is bigger than 3 which 4-3 equals 1 so then carry the negative sign down with you and that would get you your answer of -1
The local meteorologist claims that the temperature is going to steadily drop over the next 4 hours. If the temperature changes by the same amount each hour, and it changes by a total of -28°F, how much will it change each hour? Explain how you got your answer in two or more complete sentences.
Answer:
-7 degrees
Step-by-step explanation:
-28 divided by 4 equals -7. -7 x 4 = -28
Answer:
[tex]-7^{\circ}F[/tex]
Step-by-step explanation:
Let x represent temperature change per hour.
We have been given that the temperature is going to steadily drop over the next 4 hours and the temperature changes by the same amount each hour.
So temperature change in 4 hours would be [tex]4x[/tex].
We are also told that the temperature changes by a total of -28°F, so we can represent this information in equation as:
[tex]4x=-28^{\circ}F[/tex]
Let us solve for x.
[tex]\frac{4x}{4}=-\frac{28^{\circ}F}{4}[/tex]
[tex]x=-7^{\circ}F[/tex]
Therefore, the temperature changes [tex]-7^{\circ}F[/tex] each hour.

1/4 (12x−5.6)=0.5(3x+0.7)
Answer:
7/6
Step-by-step explanation:
Firstly we have to distribute it and write in this form
1/4*12x-1/4*5.6=0.5*3x+0.5*0.7
3x-1.4=1.5x+0.35 ( now that we have multiplied and simplified it we will combine like terms remember whenever you move it to the other side of equal signs it turns the opposite of the sign value eg positive to negative.
subtract 0.35 from both sides leaving the equations as 3x-1.75=1.5x
now we move 3x on other side to combine with 1.5x and 3x becomes negative
-1.75=1.5x-3x
-1.75= -1.5x (divide -1.5 from both sides
-1.75/-1.5=1.5x/-1.5
1.166666666666667=x
or 7/6 if you left the fraction as it is and didn't simplify further.
Let me know if you don't understand or need more help .
The student's algebraic equation 1/4 (12x−5.6)=0.5(3x+0.7) simplifies to x = 1.17. This is found by distributing numbers, rearrangement of terms, and final division to solve for x.
Explanation:The question is an algebraic equation that needs to be simplified and solved. First, distribute the numbers in front of the parentheses to both the terms inside. This gives:
3x - 1.4 = 1.5x + 0.35Next, rearrange terms to bring all terms involving x to one side of the equation and constants to the other side. This gives:
3x - 1.5x = 0.35 + 1.4Simplify the equation to get:
1.5x = 1.75Finally, divide by 1.5 on both sides to solve for x:
x = 1.75 / 1.5So, x = 1.17 (rounded to two decimal places).

Provide reasons for the proof.
Given: Angle 2 = angle 4
and angle 2 and angle 3 are supplementary
Prove: angle 1 = angle 3
To prove that angle 1 is equal to angle 3, we can use the given information and the properties of supplementary angles. Using substitution and algebraic manipulations, we can show that angle 1 is indeed equal to angle 3.
Explanation:To prove that angle 1 is equal to angle 3, we can use the given information and the properties of supplementary angles.
Given: angle 2 = angle 4 and angle 2 and angle 3 are supplementary.
Since angle 2 and angle 4 are equal, we can substitute angle 4 with angle 2 in the given statement, giving us angle 2 = angle 2. Now, since angle 2 and angle 3 are supplementary, their sum is 180 degrees. So angle 2 + angle 3 = 180 degrees. We can rewrite this equation as angle 2 = 180 - angle 3. Now, we can substitute angle 2 in the equation with angle 4 (which is equal to angle 2), giving us angle 4 = 180 - angle 3. Rearranging this equation, we get angle 3 = 180 - angle 4. Since angle 4 = angle 2, we can substitute angle 4 with angle 2 in the equation, giving us angle 3 = 180 - angle 2. Finally, since angle 3 = 180 - angle 2, and angle 2 = angle 4 (from the given information), we can conclude that angle 1 = angle 3.

The domain of the function is the set of values for x, given as {2,3,4}. The range, which is the set of all output values for y that result when substituting each x value in the domain into the equation, is {8,6,4}.
Explanation:In this problem, we are given an equation y + 2x = 12 and a domain D = {2,3,4}, which means x takes the values 2, 3, and 4. The domain of a function is all the possible values that x can take. Therefore, in this case, the domain (D) is {2,3,4}.
The range, on the other hand, includes all the corresponding output values that y takes for each x in the domain. The output is determined by plugging each value of the domain (x) into the equation and solving for y:
For x=2, y=12-2(2)=8. For x=3, y=12-2(3)=6. For x=4, y=12-2(4)=4.
Hence, the range for this equation, given the domain {2,3,4}, is {8,6,4}.
