The triangles are similar by the AA similarity postulate. Find the value of x
Answer:
2.5
Step-by-step explanation:
We know that they are similar and that the length of the long side is 3 + 3, which is 6. 6 = 3 times 2, meaning that all values in the big triangle are double the little triangle. That means that 2x = 5, meaning that x = 2.5.

Step-by-step explanation:
A rectangular piece of land measures 250 m by 220 m. Each side is to be fenced with 3 rows of wires. What is the length of the wire needed?
Answer:
2,820 m
Step-by-step explanation:
Given that the rectangular piece of land measures 250m by 220 m, the perimeter of the rectangle gives the length of wire required to fence it once.
The perimeter p of a rectangle of length l and width b is given as
p = 2(l + b)
Hence p = 2( 250 + 220)
= 2 * 470
= 940 m
Since each side is to be fenced with 3 rows of wires, the length of wire required
= 3 * 940m
= 2,820 m

Answer:
55
Step-by-step explanation:
since b is 110, you will have to divide 110 by 2 to find out the answer of c because its a half of b and that leaves you with 55, also a is 55 two
c=55
a=55
d=30
Answer:
∠C = 110°
Step-by-step explanation:
the figure is a kite so a line from B to D would bisect those angles and for a triangle that contains a total of 180°.
180° - 1/2(110° + 30°) = 180° - 1/2(140°) = 180° - 70° = 110°

Look at the box-and-whisker plot below comparing the scores from Pre-test A and Pre-test B. What is the difference of the lower quartiles of Pre-test A and Pre-test B?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the box and whisker plots for the Pre-test A and the Pre-test B are not given. I will answer this question with the attached image.
The attached image contains three plots.
The first plot shows the description of how to read the box and whisker plot.
From the description image, the following represents the summary of the plot
The green line: Minimum
The blue line: Lower Quartile (Q1)
The red line: Median (Q2)
The yellow line: Upper Quartile (Q3)
The last green line: Maximum
Using the above descriptions to read the pre-test A and pre-test B plots.
The lower quartile of pre-test A is:
[tex]Pre\ test\ A = 11[/tex]
The lower quartile of pre-test B is:
[tex]Pre\ test\ B = 16[/tex]
The difference (D) is calculated as:
[tex]D = |Pre\ test\ A - Pre\ test\ B|[/tex]
[tex]D = |11 - 16|[/tex]
[tex]D = |- 5|[/tex]
[tex]D = 5[/tex]
The difference is 5

A new car is purchased for 23900 dollars. The value of the car depreciates at 9.25% per year. To the nearest tenth of a year, how long will it be until the value of the car is 6000 dollars?
9514 1404 393
Answer:
14.2 years
Step-by-step explanation:
The value is described by the exponential function ...
y = (initial value)·(decay factor)^x
where y is the value after x years.
The decay factor is (1 - annual depreciation) = 1 - 0.0925 = 0.9075, so we want to find x when ...
6000 = 23900·0.9075^x
6000/23900 = 0.9075^x . . . . . . . . . . . . . . divide by 23900
log(6000/23900) = x·log(0.9075) . . . . . . . take logarithms
x = log(6000/23900)/log(0.9075) ≈ 14.2396
It will be about 14.2 years until the value of the car is $6000.

If total expenditure of firm is Rs. 1000 i). Price of labour (PL)is Rs 200. ii). |Price of capital (PK) is Rs. 100, then determine the budget line for the firm? (
Answer:
[tex]L + 2K = 200[/tex]
Step-by-step explanation:
Given
[tex]E=1000[/tex] --- Expenditure
[tex]L=200[/tex] --- Labor
[tex]K = 100[/tex] --- Capital
Required
Determine the budget line
First, we calculate the units of labor
[tex]U_1 = \frac{E}{L}[/tex]
[tex]U_1 = \frac{1000}{200}[/tex]
[tex]U_1 = 5[/tex]
Next, the units of capital
[tex]U_2 = \frac{E}{K}[/tex]
[tex]U_2 = \frac{1000}{100}[/tex]
[tex]U_2 = 10[/tex]
The budget line equation is:
[tex]U_1 * L + U_2 * K = E[/tex]
At this point, we take L and K as variables.
So, the equation becomes
[tex]5* L + 10* K = 1000[/tex]
[tex]5 L + 10K = 1000[/tex]
Divide through by 5
[tex]L + 2K = 200[/tex] -- Budget line equation

What is the area of the frame in square units around the picture? 12 8 45 6s Enter the expression in the box. square units
Answer:
Step-by-step explanation:
The area of frame is 40s square units.
What is area?The measurement that conveys the size of a plane or curved surface is known as area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina. The amount of material with a given thickness that would be required to create a model of the shape is known as area.
Given a frame whose inner dimesons are,
inner length = l₁ = 8 units
inner breadth = b₁ = 4s units
outer dimensions are,
outer length = l₂ = 12 units
outer breadth = b₂ = 6s units
area of frame = outer area - inner area
area of frame = l₂b₂ - l₁b₁
area of frame = 12(6s) - 8(4s)
area of frame = 72s - 32s
area of frame = 40s square units
Hence the area of frame is 40s square units.
