Answer:
1 (2/3)meter
Step-by-step explanation:
3(1/2) = 7/2 = 21/6
1(5/6) = 11/6
21/6 - 11/6 = 10/6 = 5/3 = 1 (2/3)

What is the area of the rectangle
Answer:
B) [tex]\frac{15}{4}[/tex]
Step-by-step explanation:
Area of a rectangle formula:
A = bh
Given:
b = [tex]2\frac{1}{2}[/tex]
h = [tex]1\frac{1}{2}[/tex]
Work:
A = bh
A = [tex](2\frac{1}{2} )(1\frac{1}{2} )[/tex]
A = [tex]\frac{15}{4}[/tex]

What is the area, in square feet, of the shaded part of the rectangle below?
===============================================
Work Shown:
A = area of the rectangle
A = length*width
A = 16*17
A = 272 sq ft
B = area of triangle
B = base*height/2
B = 16*8/2 ..... note that 17-9 = 8
B = 16*4
B = 64 sq ft
C = area of shaded trapezoid
C = A - B
C = 272 - 64
C = 208 sq ft
--------------------
Alternative Method:
Apply the trapezoid area formula
b1 = 17 and b2 = 9 are the parallel bases
h = 16 is the height perpendicular to either base
A = h*(b1+b2)/2
A = 16*(17+9)/2
A = 16*(26)/2
A = 16*13
A = 208 sq ft
Solve for X please help
Answer:
x = 10
Step-by-step explanation:
First square both sides of the equation...
[tex]2\sqrt{x + 8} = 3\sqrt{x - 2} \\(2\sqrt{x + 8})^{2} = (3\sqrt{x - 2})^{2} \\ 4(x + 8) = 9(x - 2)\\4x + 32 = 9x - 18\\-5x = -50\\x = 10[/tex]

Find the value of x in the isosceles triangle shown below
Answer:
The answer is 12
Hope it helps
Answer:
x = 12
Step-by-step explanation:
Since the 2 legs and base angles are congruent the triangle is isosceles.
The line from the vertex to the base is a perpendicular bisector dividing the triangle into 2 right triangles.
Using Pythagoras' identity in either of the 2 right triangles with legs 3 and [tex]\frac{1}{2}[/tex] x , hypotenuse [tex]\sqrt{45}[/tex] , then
([tex]\frac{1}{2}[/tex] x )² + 3² = ([tex]\sqrt{45}[/tex] )²
[tex]\frac{1}{4}[/tex] x² + 9 = 45 ( subtract 9 from both sides ²)
[tex]\frac{1}{4}[/tex] x² = 36 ( multiply both sides by 4 to clear the fraction )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12
Can someone answer this
Answer:
54
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 3, 4 ] , then
f(b) = f(4) = 81 ← value of y from table for x = 4
f(a) = f(3) = 27 ← value of y from table for x = 3
average rate of change = [tex]\frac{81-27}{4-3}[/tex] = 54

Find the median of the data in the box plot below. Cookies A horizontal boxplot titled Number of cookies eaten by each contestant, is plotted along a horizontal axis marked from 2 to 30, in increments of 1. A left whisker extends from 5 to 6. The box extends from 6 to 22 and is divided into 2 parts by a vertical line segment at 8. The right whisker extends from 22 to 25. All values estimated.
Diagrammatic representation of the summarized box plot is attached below :
Answer:
Range = 20
Median = 8
Step-by-step explanation:
The median value of a box plot is obtained at the point where a vertical line divides the box into two parts. In the boxplot Given the median of the representation is 8. This is the point where the vertical line divides the box.
The range of the distribution is the difference between the maximum and minimum value :
Minimum (starting point of whisker) = 5
Maximum (end point of whisker) = 25
Range = 25 - 5 = 20

The quality control manager of at Long John Silver's restaurant wants to analyze the length of time that a car spends at the drive-thru window waiting for an order. It is determined that the mean time spent at the window is 59.3 seconds with a standard deviation of 13.1 seconds. The distribution of time at the window is skewed right. The quality control manager wishes to use a new delivery system designed to get cars through the drive-thru system faster. A random sample of 40 cars results in a sample mean time spent at the window of 56.8 seconds. What is the probability of obtaining a sample mean of 56.8 seconds or less, assuming that the population mean is 59.3 seconds
Answer:
0.11314
Step-by-step explanation:
The Long John Silver's restaurant parameters are;
The mean time spent at the window, μ = 59.3
The standard deviation, σ = 13.1
The time distribution is skewed right
The number of cars in the sample, n = 40 cars
The mean time spent at the window with the delivery system, [tex]\overline x[/tex] = 56.8 seconds
The Z-value for a mean time of 56.8 seconds is given as follows;
[tex]Z=\dfrac{\bar{x}-\mu }{\dfrac{\sigma }{\sqrt{n}}}[/tex]
Therefore, we get;
[tex]Z=\dfrac{56.8-59.3 }{\dfrac{13.1 }{\sqrt{40}}} \approx -1.20697620617[/tex]
Therefore, the z-value ≈ -1.21
From the normal probability table, we have;
P([tex]\overline X[/tex] ≤ 56.8) = P(Z < -1.21) = 0.11314
The probability of obtaining a sample mean of 56.8 second or less, assuming that the population mean is 59.3 seconds P([tex]\overline X[/tex] ≤ 56.8) = 0.11314.

A rectangular garden has length twice as great as its width. A second rectangular garden has the same length as the first garden and width that is 4 meters greater than the width of the first garden. The second garden has area of 120 square meters. What is the length of the two gardens? Enter your answer in the box. m=
Answer:
24 meters
Step-by-step explanation:
First we need to show width and length as variables.
let width of garden 1 = W
let length of garden 1 = L
let width of garden 2 = w
let length of garden 2 = l
Now make equations that are explained in the question
L = 2W
l = L
w = W + 4
l × w = 120
Now with that we can find l and w.
Now by looking at the factors of 120, find the factors that work throughout the question.
That is 12 and 10.
l=12
w=10
This means that...
L=12
W=6
Now the answer is 24 meters
Answer:
12m

6x - 4y = 38
x + y = 5
Answer: y= -4/5 and x= 29/5
Step-by-step explanation:
From eqn2 , x= 5-y. Thus substituting in eqn1 will give
6(5-y)-4y=38
30-6y-4y=38
30-10y=38
-10y=38-30
-10y= 8
y=8/-10---> y= -4/5
Substituting y in eqn2 we have
x+(-4/5)=5
x=5+4/5
x=29/5
what's the answer dhdhdizdjskxi
Answer:
138 ft for the area in the proposed design of the green section.
To find the area of the whole shape, you gotta divide it into polygons. So, you find the area of the big rectangle at the bottom first: 18 x 7 = 126. That's the area of the big rectangle.
Then, you find the area of the little square on top. 4 x 4 - 16, that's the area. Then, you gotta add those two together: 126 + 16. The total area is 142 square feet.
