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.

find the equation of the horizontal line that contains the point (-4,8). express the equation using either the general form of the slope intercept form of the equation of a line
Answer: [tex]y=8[/tex]
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope and "b" is the y-intercept.
We know that this is a horizontal line. This means that:
[tex]m=0[/tex]
Knowing that this line contains the point (-4,8) we can substitute this coordinates and [tex]m=0[/tex] into [tex]y=mx+b[/tex], and then solve for "b":
[tex]8=0(-4)+b\\\\b=8[/tex]
Therefore, the equation of this line in Slope-intercept form is:
[tex]y=(0)x+8\\\\y=8[/tex]
Final answer:
The equation of the horizontal line that contains the point (-4,8) is y = 8 and it demonstrates that for a horizontal line, the slope is 0 and the y-coordinate remains constant along the line.
Explanation:
The equation of a horizontal line that contains a given point can be determined by looking at the y-coordinate of that point. Since a horizontal line has a slope of 0, the y-coordinate of any point on the line does not change. Therefore, the equation of the horizontal line that contains the point (-4,8) is simply y = 8. This equation indicates that the y-value will always be 8, regardless of the x-value, which is characteristic of a horizontal line. In the slope-intercept form of the equation of a line, which is y = mx + b, the slope (m) is 0, and the y-intercept (b) is 8.

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.

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.

Polygon ABCD is a parallelogram, and m2ABC = 127°. The length of BC Is 10 units, and the length of AB is 5 units.
The perimeter of the parallelogram is ————
units, and mZBCD IS ——- degrees
Answer:
The perimeter is 30 and the angle is 53.
Step-by-step explanation:
The perimeter is found by adding the length of all four sides. Two sides are 10 units and two sides are 5 units. 10+10+5+5 = 30.
The angle is found by subtracting angle ABC's value from 180.
180 - 127 = 53.
The perimeter of a parallelogram ABCD is 30 units and the measure of angle BCD is 53°.
What is parallelogram?A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.
Given that, from given parallelogram ABCD, m∠ABC=127°.
The length of BC Is 10 units, and the length of AB is 5 units.
Here, the perimeter of of a parallelogram is AB+BC+CD+DA
= 10+5+10+5
= 30 units
Here, m∠ABC+m∠BCD=180° (Sum of co-interior angles is 180°)
127°+m∠BCD=180°
m∠BCD=180°-127°
m∠BCD=53°
Therefore, the perimeter of a parallelogram ABCD is 30 units and the measure of angle BCD is 53°.

Nat’s grocery bill was $150, which includes a 5% club discount. What was nats bill before the discounts
Answer:
$157.89
Step-by-step explanation:
The original price is x
you took away 5%, making the new price 95% of x, or .95x
Put it in an equation
.95x = 150
x = 150/.95
x = 30/.19
x = 3000/19
x=157 17/19
x is about $157.89
The amount Nat's paid at the club before the discount is $157.90
Given:
Total bill including discount = $150
Discount = $5
Amount before discount = x
Total bill including discount = Amount before discount - (Discount × Amount before discount)
150 = x - (5% × x)
150 = x - (0.05 × x)
150 = x - 0.05x
150 = 0.95x
divide both sides by 0.95
x = 150 / 0.95
x = 157.89473684210
Approximately,
x = $157.90
Therefore, amount Nat's paid at the club before the discount is $157.90

Find Sn for the given arithmetic series.
a1 = 18, d = –3, n = 14
Answer:
- 21
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ], thus
[tex]S_{14}[/tex] = [tex]\frac{14}{2}[/tex][( 2 × 18) + (13 × - 3) ]
= 7 (36 - 39) = 7 × - 3 = - 21
The sum of the arithmetic series with the first term 18, common difference -3, and 14 terms is 231.
Explanation:To find the sum, Sn, of an arithmetic series where a1 is the first term, d is the common difference, and n is the number of terms, you can use the formula:
Sn = ⅓n × (a1 + an)
First, find the nth term (an) using the formula:
an = a1 + (n - 1)d
For a1 = 18, d = –3, and n = 14:
an = 18 + (14 - 1)(-3)
an = 18 - 39 = –21
Sn = ⅓(14) × (18 + (–21))
Sn = 7 × (18 - 3) × 33
Sn = 231
So, the sum of the series is 231.

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
