These shapes (in the photo attached) are similar. Find the value of x.
Please help nobody has been answering!!!
Answer:
x = 14
Step-by-step explanation:
We can calculate the value of x using similarity ratio
22/4 = x/3 cross multiply expressions
66 = 4x divide both sides by 4
x = 14

Ali was asked to simplify the expression 3(x - 6) + (4x + 12) - 6x. His work is shown below.
3(x - 6) + (4x + 12) - 6x
3x - 9 + 4x + 12 - 6x
(3x + 4x - 6x) + (-9 + 12)
x + 3
Answer:
Step 2 is wrong.
It should be 3x – 18 + 4x + 12 – 6x
Explanation:
3(x – 6) + (4x + 12) – 6x →
3x – 18 + 4x + 12 – 6x →
(3x + 4x – 6x) + (-18 + 12) →
x – 6

Select the table representing a linear function. (Graph them if necessary)
Answer:
B
Step-by-step explanation:
There are a couple of ways you can go about solving this. The first is plotting all of the points and seeing which one makes a straight line. This is a little bit more time consuming but is great if you blank out and forget how to solve it. The faster way to do it is to see which function is decreasing/increase a constant amount between equal intervals. A increases but by a different amount each time. B decreases by 2 each time. C decreases at different intervals each time. And D does not consistently increase or decrease.
Are the ratios 5:3 and 6:4 equivalent?
yes
no
Answer:
nope
Step-by-step explanation:
The given ratios 5:3 and 6:4 are not equivalent.
What are Equivalent ratios?Equivalent ratios are the ratios that are the same when we compare them. Example 1/2 and 2/4 are equivalent ratios.
Two or more ratios can be compared with each other to check whether they are equivalent or not.
The given two ratios are 5:3 and 6:4
We can write them as 5/3 and 6/4
Let us apply subtraction, if we get 0 then these are equivalent.
6/4-5/3
The LCM of 4 and 3 is 12
=(18-20)/12
The value of 18-20 is -2
=-2/12
We have to divide 2 by 12 we get -1/6.
=-1/6 not equal to 0
The ratios 5:3 and 6:4 are not equivalent.

if £2000 is placed into a bank account that pays 3% compound interest per year how much will be in account after 2 years?
Answer:
£2121.80
Step-by-step explanation:
Year 1 -> 2000 + (3% of 2000) = 2000 + (60) = 2060
Year 2 -> 2060 + (3% of 2060) = 2060 + (61.80) = 2121.80

The time (t) required to finish a certain job is inversely
proportional to the number of persons (p) on the job. If 10
persons can finish the job in 6 hours, how long will it take
for 30 persons to finish the job?
18 hours
Step-by-step explanation:
6/10=0.6 hours (one person takes 0.6 hour)
0.6×30=18 hours
or another way 10 is 1/3 of 30. so
6:1/3=18

====================================================
Explanation:
The hexagon is broken up into 6 congruent or identical equilateral triangles. If we find the area of one triangle, then we multiply by 6 to get the area of the hexagon.
Going in reverse, we divide the hexagon's area by 6 to get the area of one equilateral triangle
We're told the hexagon has an area of [tex]18\sqrt{3}[/tex] square inches. Divide this by 6 and you should get the result [tex]3\sqrt{3}[/tex]. So each of the six equilateral triangles has area of [tex]3\sqrt{3}[/tex] square inches.
-------------------------------------
Each triangle has a base of [tex]2(\sqrt{3})^{x/12}[/tex] and a height of [tex](\sqrt{3})^{x/6}[/tex]
The x/12 and x/6 are exponents.
Let [tex]b = 2(\sqrt{3})^{x/12}[/tex] and [tex]h = (\sqrt{3})^{x/6}[/tex] be the base and height respectively.
Also, let [tex]A = 3\sqrt{3}[/tex] be the area of the triangle
We can then solve for x like so:
[tex]A = 0.5*b*h\\\\3\sqrt{3} = 0.5*2(\sqrt{3})^{x/12}*(\sqrt{3})^{x/6}\\\\3*3^{1/2} = (\sqrt{3})^{x/12+x/6}\\\\3^1*3^{1/2} = (\sqrt{3})^{x/12+2x/12}\\\\3^{1+1/2} = (\sqrt{3})^{3x/12}\\\\3^{3/2} = (3^{1/2})^{x/4}\\\\3^{3/2} = 3^{(1/2)*(x/4)}\\\\3^{3/2} = 3^{x/8}\\\\[/tex]
Since the bases are equal to 3, this means the exponents must be equal as well (for both sides overall to be equal)
3/2 = x/8
3*8 = 2*x ... cross multiply
24 = 2x
2x = 24
x = 24/2
x = 12
The length and breadth of rectangular field are 240m and 200m respectively. Find the cost of digging the field at Rs 10 per m^2
Answer:
Please check the explanation.
Step-by-step explanation:
Given
The length of rectangular field = l = 240mThe breadth of rectangular field = w = 200mWe can determine the area of the rectangular field using the equation
[tex]A=wl[/tex]
where
[tex]l[/tex] is the length [tex]w[/tex] is the widthsubstituting l = 240m, and w = 200m in the formula
[tex]A=wl[/tex]
A = 240 × 200
A = 48000 m²
Given that the cost of digging the field at Rs 10 per m².
Thus,
The cost of digging the field of the area 48000 m² = 10 × 48000
= 480000 Rs
Therefore, the total cost of digging = 480000 Rs

Answer:
The equation is;
y = -2x + 1
the answer belonging in the green question mark is -2
Step-by-step explanation:
We start by getting the slope
The slope can be obtained by selecting any two points and applying the slope formula
let us select the points;
(1,-1) and (3,-5)
the slope formula is;
m = (y2-y1)/(x2-x1)
m = (-5-(-1)/(3-1)
m = (-5+1)/2 = -4/2 = -2
The y intercept is the value of y when x = 0
As it can be seen, y = 1 when x = 0
so the equation of the relation is;
y = -2x + 1

two brothers, richard and andrew share a sum £30 in the ratio 3:7 how much does each brother get?
Answer:
Richard gets: £9
Andrew gets: £21
Step-by-step explanation:
To get the value of 1 part we have to add the total number of parts (3+7) and then divide them by the sum (30) 30/10 = 3 so we know 1 part is £3
Thus Richard gets: £3*3 = £9
And Andrew gets: £3*7 = £21

A new arrow needs to be painted on the road to direct traffic.
What shapes can the figure be broken into?
What is the area of the arrow?
I
7 ft
1 ft
2 ft
11 ft
Answer:
The arrow can be broken into a rectangle and a triangle.
And the area of the arrow is 22 ft^2
Step-by-step explanation:
Area of the rectangle:
length • width = 7 • 2 = 14 ft^2
Area of the triangle:
(base • height) / 2
You must add 1 + 2 + 1 in order to get the base which is 4
And to get the height, you must do 11 - 7 = 4 (height)
(4 • 4) / 2 = 8 ft^2
Add both areas together to get the area of the arrow:
14 ft^2 + 8 ft^2 = 22 ft^2
