The number of dishes the crispy clover has in his new menu can be expressed as D + (1/5)D.
Define expression.A statement, at least two variables or integers, and one or more arithmetic operations make up a mathematical expression. This mathematical operation enables the multiplication, division, addition, and subtraction operations.
Given data -
20% more dishes are available on the new menu than the old one.
D foods were on the previous menu.
As 20% more dishes are added,
Therefore we can also write it as (20/100)D
Now the total dishes in the new menu can be expressed as
= D + (20/100)D
= D + (1/5)D
Therefore the number of dishes the crispy clover has in his new menu can be expressed as D + (1/5)D.

At cliffs of insanity point, the great sasquatch canyon is 7117 feet deep. from that point, a fire is seen at a location known to be 10 miles away from the base of the sheer canyon wall. what angle of depression is made by the line of sight from the canyon edge to the fire? express your answer using degree measure rounded to one decimal place.
Angle of depression is 7.7 ° made by the line of sight from the canyon edge to the fire .
What is angle of depression ?The angle of depression is the angle created by the object and the horizontal line as seen from the horizontal line. The distance between two objects is often calculated when the angles and spacing of an object from the ground are known.
Calculationlet f be the the fire
b is the base of the sheer canyon wall
o be the cliffs of insanity point that is canyon edge
so OB = 7117 Feet
bf = 10 miles = 10 * 5280 = 52800 feet
angle of depression is < xof which is equal to < ofb
let the angle of depression is [tex]\theta[/tex]
now from triangle obf ; it is a right angle triangle , where of = hypotenuse
bf = base , ob = height < ofb = [tex]\theta[/tex]
so , tan [tex]\theta[/tex] = ob/bf = 7117/52800
[tex]\theta[/tex] = [tex]tan^{-1}[/tex] ( 7117/52800) = 7.68 ° = 7.7 °
so angle of depression is 7.7 °

x-intercept of the linear equation that is parallel to y=-3x-5 and passes through (2, 6) is 4
What is the equation of the line?
The slope of the line and a point on the line can be used to create the equation of a line.
The slope of the line, which can be stated as a numeric integer, fraction, or the tangent of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis. The coordinate system's point with the x coordinate and the y coordinate is referred to as the point.
Given equation of line is y = -3x - 5
Passing points (a,b) = (2,6)
As we know equation of the line is y = mx + c where m is the slope of the line and c is the y-intercept
On comparing the given equation of the line with y = mx + c , we have slope of the line is -3
Slope of two parallel lines is equal.
Equation of line having slope and passing point is given by y-b = m (x-a)
Therefore, equation of line having slope -3 and passing point (2,6) is y - 6 = -3(x - 2)
⇒ y - 6 = -3x + 6
⇒ y = -3x + 6 + 6
⇒ y = -3x + 12
Equation of line having slope and x-intercept is given by y = m(x - a) where m is the slope and a is the x- intercept
y = -3x + 12 can be written as y = -3(x-4)
On comparing this equation with y = m(x-a) we have x-intercept is 4
Therefore, x-intercept of the linear equation that is parallel to y=-3x-5 and passes through (2, 6) is 4

Robert needs to cut four shelves from a board that is meters long. The second shelf is centimeters longer than twice the length of the first shelf. The third shelf is centimeters shorter than the first shelf. The remaining shelf is centimeters longer than the first shelf. If robert must use the entire meter board for the shelves, what is the length of the second shelf, in centimeters?.
The length of the second shelf is 114 centimetres.
Consider the four shelves as A, B, C and D. According to the question, the length of the four shelves is 2.5 cm.
A + B + C + D = 250 cm ( 1 m = 100 cm ⇒ 2.5 * 100 = 250 ) → 1
The length of the second shelf is 18 cm longer than twice the length of the first shelf.
B = 2A + 18 → i
The length of the third shelf is 12 cm shorter than the first shelf.
C = A - 12 → ii
The length of the fourth shelf is 4 cm longer than the first shelf.
D = A + 4 → iii
Substitute i,ii and iii in 1 ⇒ A + B + C + D = 250
A + 2A + 18 + A - 12 + A + 4 = 250
5A + 22 - 12 = 250
5A + 10 = 250
5A = 250 - 10
5A = 240
A = 240/5
A = 48
Substitute A = 48 in i, ii, iii and then we get,
B = 11, C = 36 and D = 52
Therefore, the length of the second shelf B is 114 cm.

To find the mean, median and mode.
Let's Know :
How do you find the mean median and mode?
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.
Now, According to the above statement :
To find Mean:
[tex]\frac{3+4+ 5+ 7+ 6+ 8+ 8+ 5+ 3+ 6+ 4+ 5+ 3+ 3+ 7+ 7}{16}[/tex]
= 84/16 = 5.25
For Median
Arrange in ascending order
3, 3, 3, 3, 4,4, 5,5,5, 6,6, 7, 7, 7, 8,8.
There is an even no. of observations. i.e., 16 numbers.
then, there is no single middle value; the median is then usually defined to be the mean of the two middle values: so the median of
Middle two values is : (5 + 5)/2 = 10/2 = 5
Middle value is 5
For Mode:
The mode is the number that occurs most often in a data set.

Use exact numbers.
y−6= [ ]
y-6 = -5/3 (x+2) is the point - slope equation of the line through (-2 , 6 ) ( 1 , 1 ) using exact numbers.
What is point - slope equation ?For linear equations, the typical form is y-y1=m(x-x1). It highlights the line's slope and a line point (that is not the y-intercept).
The two approaches for determining the equation of a line given a point and its slope are as follows:
(a). Input the slope and the (x, y) point values into the equation y = mx + b, then solve for b using the substitution technique
b) Point-slope form: (x 1, y 1), where (y 1, x 1) is the point and (m, the slope) is the specified slope.
CalculationFirst you need to find the slope, (y2-y1)/(x2-x1). This is (1-6)/(1-(-2)) or -5/3
Now that you know the slope you can use that for the point-slope equation
The point-slope equation is y-y1 = m(x-x1). If we start with y-6, the x value is -2 (from our point (-2,6)
y-6 = -5/3 (x-(-2))
