Answer:
16 cmStep-by-step explanation:
Use ratios to solve:
125 m ⇒ 25 cm80 m ⇒ x cmFind the value of x:
x = 80*25/125 = 16The length of the building on the scale drawing for the given context is obtained as: 16 cm.
How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
For the given case, The height of the building 125 meters was drawn as 25 cm in the scale drawing.
That means:
[tex]\rm 125 \: m : 25 \: cm\\\\1 \: m : \dfrac{25}{125} \: cm\\\\1 \: m :\dfrac{1}{5} \: \rm cm[/tex]
Since the length of the building in reality is 80 meters.
Thus, in scale drawing, it would become:
[tex]\rm 80 \: m = 80 \times 1 \: m : 80 \times \dfrac{1}{5} \: cm = 16 \: \rm cm[/tex]
Thus, The length of the building on the scale drawing for the given context is obtained as being of 16 cm.

What is f '(x) for f(x) = secxcscx?
f(x)=secxcscx
let secx=g(x)
let cscx=h(x)
therefore, using leibnitz rule,
f'(x)=g'(x)*h(x)+h'(x)*g(x)
Since derivative of secx=secxtanx
and derivative of cscx=-cscxcotx,
f'(x)=secxtanxcscx -cscxcotxsecx
=1/cosx*sinx/cosx*1/sinx - 1/sinx*cosx/sinx*1/cosx
=1/cos^2x-1/sin^2x
=(sin^2x-cos^2x)/sin^2xcos^2x / Option1
The value of f'(x) is (sin^2x - cos^2x)/sin^2x cos^2x. Thus, option A is correct.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Given;
f(x) = secx cscx
let secx = g(x)
let cscx = h(x)
Using Leibnitz rule,
f'(x) = g'(x)h(x) + h'(x)g(x)
Since the derivative of secx = secx tanx
derivative of cscx = -cscx cotx,
f'(x) = secx tanx cscx - cscx cotx secx
f'(x) = 1/cosx sinx/cosx 1/sinx - 1/sinx cosx/sinx 1/cosx
f'(x) =1/cos^2x - 1/sin^2x
f'(x) = (sin^2x - cos^2x)/sin^2x cos^2x
Thus, option A is correct.

Step-by-step explanation:
All % can be rewritten by moving the decimal 2 places to the left, (88% turns to .88)
Divide the fractions to get thier decimals
8/10 goes to .80
8/11 goes to .727272...
Now just put them in order
.7272, .78, .88, .90, .94 (Least to greatest)
.94, .90, .88, .78, .7272 (Greatest to least (What the problem wants))
Now convert them to the original form

Mia buys a tablet in $500. and plans to sell it in 2 years. the tablet value is projected to decrease for 40% per year. for how much Mia is expected to sell her tablet?
Answer:
$100
Step-by-step explanation:
$500 x [tex](1-40-40[/tex]%[tex])\\[/tex]
= $500 x 20%
= $100
$ 100 is for Mia expected.
Mia is expected to sell her tablet for $100 because its value is projected to decrease for 40% per year.
Given the following data:
Cost of tablet = $500Time = 2 yearsDepreciation rate = 40% per year = 0.4To find how much Mia is expected to sell her tablet:
First of all, we would determine the depreciation for the two year.
[tex]Two \;years = 0.4(2) = 0.8[/tex]
The depreciation cost:
[tex]500[/tex] × [tex]0.8 = 400[/tex]
Now, we would solve for the selling price by using the formula:
[tex]Selling\;price = Cost\;price - Depreciation\;cost\\\\Selling\;price = 500 - 400[/tex]
Selling price = $100
Therefore, Mia is expected to sell her tablet for $100 because its value is projected to decrease for 40% per year.

Jasmine pays £52.40 for 40 litres of petrol. What is the cost per litre?
Answer:
1.31
Step-by-step explanation:
52.40÷40=1.31
I hope this helps:)
Jasmine's cost per liter of petrol is £1.31 when she pays £52.40 for 40 liters.
Total-Cost is divided by the quantity of units (liters) to find out how much each unit costs.
We know that : Cost of petrol is = £52.40,
The Quantity of petrol is = 40 liters,
The Cost per-liter can be calculated as = Total cost / Quantity of petrol
Substituting the values,
We get,
Cost per liter = £52.40/40,
Cost per liter = £1.31,
The concept of dividing the total cost by the quantity gives you a standard way to measure and compare costs on per-unit basis.
Therefore, the required cost per liter of petrol for Jasmine is £1.31.

A number x is no less than -42
Step-by-step explanation:
It mean more than -42 or equal to -42
please give me a brainliest answer
The inequality that represents the statement "A number x is no less than -42" is x ≥ -42.
The inequality that represents the statement "A number x is no less than -42" can be expressed as:
x ≥ -42
In this inequality, the symbol "≥" stands for "greater than or equal to." It indicates that "x" can take any value that is equal to -42 or any value greater than -42. If "x" equals -42, the condition is satisfied, and if "x" is greater than -42, the condition is also satisfied.
For instance, if "x" is -40, the inequality holds true, as -40 is greater than -42. Similarly, if "x" is 0 or any positive number, the inequality remains true, as all these values are greater than -42.
