Answer: x is 9° , y is 21°. The measure of angle ABE is 48°.
Step-by-step explanation:
First we will solve for x.
The variable x appears in the angle 8x + 18 and that angle is a right angle.
Right angles have the measure of 90 degrees so we will set the angle equal 90 and solve for x.
8x + 18 = 90 Subtract 18 from both sides
- 18 -18
8x = 72 divide both sides by 8
x = 9
y is also on the right side and the combination of both angles has to also equal 90 degrees because they form a right angle.
Since we already know x is 9 we will input it into the left side for x and solve for y.
y + 3(9) + 2y = 90
3y + 27= 90
-27 -27
3y = 63
y = 21
Now we need to find the measure of angle ABE.
ABE is represented by y + 3x so since we know the value of y and x we will input it into the expression and solve for the angle.
21 + 3(9) = m∠ABE
21 + 27= m∠ABE
48 = m∠ABE
This means the measure of angle ABE is 48°

A rectangular piece of metal is 9 in. longer than it is wide, Squares with sides 4 in. long are cut from the four corners, and the flaps are folded upward to form an open box. Which equation indicates that the volume of the box is 56 in.³?
Choose the correct answer below.
OA (x+1)(x-8)=56
OB. x(x +9)(4)=56
OC. (x+1)(x-8)(4)=56
OD. x(x +9)=56
OC (x+1)(x-8)(4)=56 indicates that the volume of the box is 56 in³ because it takes into account the length of the sides after the four corners were cut off, and the height of the box which is 4 in. The equation can be written as (length of sides)(width of sides)(height) = volume.
What is a volume?A volume is a three-dimensional space that contains a specific amount of material, which is commonly measured in liters, cubic meters, or gallons. It is frequently used to calculate the capacity of containers like tanks, bottles, and barrels. Volume may also refer to the quantity of space occupied by an item, such as the volume of a room or the volume of a sphere.
In the given question, OC is the correct answer: (x+1)(x-8)(4)=56. This equation reveals that the volume of the box is 56 \(in^{3}\) because it considers the length of the sides after the four corners were taken off, which are (x+1) and (x-8), as well as the height of the box, which is 4 in. The formula is (length of sides)(width of sides)(height) Equals volume. As a result, the equation (x+1)(x-8)(4) = 56 reveals that the box's volume is 56 \(in^{3}\).

\(\sf\longrightarrow\) 16x -12° = 180°
\(\sf\longrightarrow\) 16x = 180° + 12°

the burning times of scented candles, in minutes, are normally distributed with a mean of 249 minutes and a standard deviation of 20 minutes. find the number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles. use excel, and round your answer to two decimal places.
The number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles is 244 minutes.
When the distribution is normal, we use the z-score formula.
In a set with mean µ and standard deviation σ , the z-score of a measure X is given by:
Z = (X – µ) / σ
What is Z-score?The Z-score shows how many standard deviations the measure is from the mean. After finding the Z-score, need to look at the z-score table and discover the p-value associated with the z-score. This p-value is the probability that the value of the measure is smaller than X, means, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
So, in this case, given that:
µ = 249, σ = 20
The number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles:
100 – 80 = 20th percentile, which is X when Z has a p-value of 0.2. So, X when Z = –0.253.
Now, put all the values into the formula:
Z = (X – µ) / σ
–0.253 = (X – 249) / 20
X – 249 = –0.253 * 20
X = 244
Hence, the candle burns for 244 minutes.

\(\large \boxed{\displaystyle y = \frac{1}{5} x + 2}\)
\(\large \boxed{\displaystyle y = x - \frac{1}{4}}\)
\(\large \boxed{y=-2x+4}\)
Step-by-step explanation:
\(5y - x = 10\)
Add x to both sides
\(5y = x + 10\)
Divide both sides by 5
\(\displaystyle y = \frac{1}{5} x + 2\)
\(-4y + 4x = 1\)
Subtract 4x from both sides
\(-4y = -4x + 1\)
Divide both sides by -4
\(\displaystyle y = x - \frac{1}{4}\)
\(3y+6x=12\)
Subtract 6x from both sides
\(3y=-6x+12\)
Divide both sides by 3
\(y=-2x+4\)
2x+y=3
Зу = 18 -6x

find the quotient and remainder when 6x^4+ 11x^3+13x^2 -3x+27 is divided by 3x+4. also check the remainder obtained by using the remainder theorem.
The division of 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 will have a quotient of 2x³ + x² +3x -5 and a remainder of 47 using the remainder theorem.
What is the remainder theoremThe remainder theorem states that if a polynomial say f(x) is divided by x - a, then the remainder is f(a).
We shall divide the 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 as follows;
x⁴ divided by 3x equals 2x³
3x + 4 multiplied by 2x³ equals 6x⁴ + 8x³
subtract 6x⁴ + 8x³ from 6x⁴ + 11x³ + 13x² - 3x + 27 will give us 3x³ + 13x² - 3x + 27
3x³ divided by 3x equals x²
3x + 4 multiplied by x² equals 3x³ + 4x²
subtract 3x³ + 4x² from 3x³ + 13x² - 3x + 27 will give us 9x² - 3x + 27
9x² divided by 3x equals 3x
3x + 4 multiplied by 3x equals 9x² + 12x
subtract 9x² + 12x from 9x² - 3x + 27 will give us -15x + 27
-15x divided by 3x equals -5
3x + 4 multiplied by -5 equals -15x - 20
subtract -15x - 20 from -15x + 27 will result to a remainder of 47
using the remainder theorem, x = -4/3 from the the divisor 3x + 4
thus:
f(-4/3) = 6(-4/3)⁴ + 11(-4/3)³ + 13(-4/3)² - 3(-4/3) + 27 {putting the value -4/3 for x}
f(-4/3) = (1536/81) - (704/27) + (208/9) + (12/3) + 27
f(-4/3) = (1536 - 2112 + 1872 + 324 + 2157)/81 {simplification by taking the LCM of the denominators}
f(-4/3) = (5919 - 2112)/81
f(-4/3) = 3807/81
f(-4/3) = 47
Therefore, the quotient of after the division of 6x⁴ + 11x³ + 13x² - 3x + 27 by 3x + 4 is 2x³ + x² +3x -5 and there is the remainder of 47 using the remainder theorem.

what is the perimeter of square abcd? units units 28 units 37 units
The perimeter of square ABCD is 28 units.
The perimeter of a square is the sum of all its sides. In this case, we need to find the perimeter of square ABCD.
The question provides two possible answers: 28 units and 37 units. However, we can only choose one correct answer. To determine the correct answer, let's think step by step.
A square has all four sides equal in length. Therefore, if we know the length of one side, we can find the perimeter.
If the perimeter of the square is 28 units, that would mean each side is 28/4 = 7 units long. However, if the perimeter is 37 units, that would mean each side is 37/4 = 9.25 units long.
Since a side length of 9.25 units is not a whole number, it is unlikely to be the correct answer. Hence, the perimeter of square ABCD is most likely 28 units.
In conclusion, the perimeter of square ABCD is 28 units.

C. (3. 9, 2. 3)
D. (2. 3, -3. 9)
The rectangular coordinates for (4.5, -30 degrees) are (3.9, -2.3), which is option B.
What is rectangle ?
A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle.
To find the rectangular coordinates for a point in a plane given its polar coordinates, use the following formula:
x = r * cos(θ)
y = r * sin(θ)
Where (r, θ) are the polar coordinates and (x, y) are the rectangular coordinates.
For the point (4.5, -30 degrees), have:
r = 4.5
θ = -30 degrees = -30 * (π / 180) radians
x = r * cos(θ) = 4.5 * cos(-30 * (π / 180)) = 3.9
y = r * sin(θ) = 4.5 * sin(-30 * (π / 180)) = -2.3
So, the rectangular coordinates for (4.5, -30 degrees) are (3.9, -2.3), which is option B.

The rectangular coordinates for (4. 5, -30 degrees) are (3.9, -2.3).
The rectangular coordinates for (4.5, -30 degrees) can be found using the following formula:
x = r * cos(θ)
y = r * sin(θ)
where r is the magnitude (or distance from the origin) and θ is the angle in radians.
In this case, r = 4.5 and θ = -30 degrees = -30 * (π/180) radians.
So:
x = 4.5 * cos(-30 * (π/180)) = 4.5 * cos(-π/6) = 4.5 * sqrt(3)/2
y = 4.5 * sin(-30 * (π/180)) = 4.5 * sin(-π/6) = -4.5 / 2
Therefore, the rectangular coordinates are (x, y) = (4.5 * sqrt(3)/2, -4.5 / 2), which is approximately (3.9, -2.3).
Option B (3.9, -2.3) is the right response as a result.
