Answer:
The expansion of a metre stick (also known as meter stick) in the Sun will affect the meters stick accuracy by reducing the values of the actual length of the dimensions measured with the meter stick
The linear expansion, ΔL, of the meter stick is given according to the following formula;
ΔL = ∝·L₀·ΔT
Where;
ΔL = The expansion (change in length) of the meter stick
∝ = The coefficient of linear expansion for the meter stick
L₀ = The initial length of the meter stick = 1 meter
ΔT = The temperature change of the meter stick
Due to the small value of ∝ for a meter stick, the change in length of the meter stick is small but the difference will affect the accuracy of the measurements made by the meter stick and the length of an item with actual length of 1 meter can be given by the expanded meter stick as 99 cm

What is the point-slope form of a line with slope 2 that contains the point
(1,3)?
O A. y+ 3 = -2(x-2)
B. Y-3 = 2(x-1)
O C. y+ 3 = 2(x+1)
O D. y-1 = 2(x-3)
SUBMIT
Answer:
y -3 = 2( x-1)
Step-by-step explanation:
Point slope form of a line is
y-y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line
y -3 = 2( x-1)
Xavier needs to bike a minimum of 80 miles this week for his training if he is already biked 14 miles this week and how many miles should he bike on each of the six remaining days this week?
Answer:
if he wants to bike the same amount of miles each day he should bike 11 miles each day .
Step-by-step explanation:
subtract 14 - 80 = 66. 66 in 6 days is 11 each day
If the area of a rectangular garden is 12x2−20x. What is the length if the width is 4x? 8x2−168 x squared minus 16 3x2−5x3 x squared minus 5 x 8x−168 x minus 16 3x−5
Answer:
3x - 5
Step-by-step explanation:
If the area of a rectangular garden is 12x²−20x. What is the length if the width is 4x?
The formula for the Area of a rectangular shape = Length × Width
Area = 12x² - 20x
Length = 4x
Width = Area/Length
Width = 12x² - 20x/4x
Width = 12x²/4x - 20x/4x
Width = 3x - 5
The width of the Rectangular shape = 3x - 5

Which expression represents the area of the figure?
Answer:
Option A
The Area of the given figure is 5x²/2 + 3x/2 - 4
Step-by-step explanation:
For a given Trapezoid
side a = x + 7
side b = 4x + 1
height (h) = x - 1
Now, Area of Trapezoid
Formula:A = ½ (a + b) × h
A = ½ (x + 7 + 4x + 1) × (x - 1)
A = ½ (5x + 8) × (x - 1)
A = ½ (5x² - 5x + 8x - 8)
A = ½ (5x² + 3x - 8)
A = 5x²/2 + 3x/2 - 8/2
A = 5x²/2 + 3x/2 - 4
Thus, The Area of the given figure is
5x²/2 + 3x/2 - 4

State if the triangles in each pair are similar. If so, complete the similarity statement.
Answer:
B
Step-by-step explanation:
Set up a proportion and see if it is true:
[tex]\frac{12}{8} =\frac{27}{18} \\\frac{3}{2} =\frac{3}{2}[/tex]
True, so they are similar.
The similarity statement would be QRS ~ QED
So B is the answer
Rachels company invest 2200 for her each year she works for the company. The investments earns 2.3% simple interest each year. Rachel has worked for this company for one year how much is her investment worth?
Answer:
Step-by-step explanation:
2250.6
Rachel's investment is worth $2251.60 after the first year.
What is the simple interest?Simple interest is defined as interest paid on the original principal and calculated with the following formula:
S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100
The investments earn 2.3% simple interest each year.
The interest earned in the first year is calculated as follows:
Interest = (2.3/100) x $2200
Apply the multiplication operation, and we get
Interest = $51.60
So, Rachel's investment is worth $2200 + $51.60 = $2251.60 after the first year.

I need help with this question and I was wondering if I can get some help with it
Answer:
26.75
Step-by-step explanation:
You have to break up the whole shape into smaller ones.
To find the area of a triangle, you multiply the base x height and divide by 2.
The first smaller shape is the right triangle in the bottom left. To find the area you multiply 2(2), which is 4. Then divide by 2, which is 2.
The next shape is the square in the bottom middle. The area is simply 2(2)=4.
The next shape is the triangle in the bottom right. To find the area you multiply 2(5)/2=5.
The last shape is the triangle on top. The base is 3.5. The height though, you have to add the height for all 3 shapes on the bottom. 2+2+5=9. 3.5(9)/2=15.75
Finally, add up all of the areas. 2+4+5+15.75=26.75
The ratio of number of men to the number of women in the auditorium is 4:7. The number
of men is 487.
2.3.1 Determine the number of women in the auditorium.
The ratio 4:7 means for every 4 men there are 7 women.
Divide total number of men by 4:
487/4 = 121.75
Multiply that by 7:
121.75*7 = 852.25 Round to the nearest whole number.
There is approximately 852 women.

What are the missing numbers?
Answer:
You can use the formula 500 * 1.03^x to solve for any year.
year 4 is 500 * 1.03^(4) = 562.75
year 6 is 500 * 1.03^(6) = 597.03
Year 7 is 500 * 1.03^(7) = 614.94
Step-by-step explanation:
The amount is increasing, and there are two main ways for that to happen. Addition and multiplication. So let's see if it keeps getting the same amount added or multiplied.
0 to 1 goes from 500 to 515, so 15 is added. but 15.45 is added from 1 to 2, so we can't just do simple addition.
using multiplication 0 to 1 has 1.03 multiplied. if you multiply by it again you do get 530.45, so we have established what is happening.
You can use the formula 500 * 1.03^x to solve for any year.
so year 4 is 500 * 1.03^(4) = 562.75
year 6 is 500 * 1.03^(6) = 597.03
Year 7 is 500 * 1.03^(7) = 614.94
