Answer:
Stairs, escalators, elevators, ramps...
Step-by-step explanation:
If ladders are difficult to use for high floors another very common options are stairs. you see them pretty much everywhere. Escalators and elevators are also used, elevators more often that escalators.
I don't know how to make it sound "mathy" but..
Ladders are super straight and so for high floors, the slope of the ladder will be too steep for anyone to climb without gravity interfering.
The level of safety with stairs is higher because instead of going straight up, The steps provide a flat surface for someone to stand on while climbing the stairs and there is a much more stable foundation. Stairs can have protection like a guard rail and even go in a spiral motion upwards because they are more stable and safe. It is still possible to fall if one is not careful because of pesky gravity.
Escalators are pretty much moving stairs and the level of safety is greater because of the strong foundation and flat surface to stand on. Of course falling can happen, lowering the safety, but this is not likely because of the slowly enough moving steps. There is a rail as well and as long as people are careful, there aren't usually any casualties.
Elevators take up way less space than stairs and escalators because they can go straight up and down. The level of safety is fairly high because an elevator is a pulley system and people don't involve all that much moving around. Just go in the mechanical box, the doors close for safety, click a button, and then go up or down.
I don't know how to incorporate mathematical facts into this question because this is literally logic not math in my opinion. Honestly, ladders aren't even used that much, I don't think, except for building and house work.
I hope this helps you with whatever you are doing!

Part A: Create a fourth-degree polynomial with three terms in standard form. How do you know it is in standard form?
Part B: Explain the closure property as it relates to addition of polynomials. Give an example.
Answer:
Part A: x⁴ + x³ + x²
Part B: (4·x + 2) + (-5·x + 6) = -x + 8
Step-by-step explanation:
Part A:
We note that standard form means that the terms of the polynomial are arranged in order starting from the the largest exponential of the polynomial to the smallest exponent
Therefore, we have
x⁴ + x³ + x² is a fourth-degree polynomial with three terms in standard form
It is known that the above polynomial is in standard form based on its ordered arrangement from the largest exponential to the smallest exponential
Part B:
Polynomial are closed under addition, that is when two polynomials are added only the coefficients change as the exponents and variables remain unchanged as follows;
(4·x + 2) + (-5·x + 6)
= 4·x + 2 - 5·x + 6
= 4·x - 5·x + 2 + 6
= -x + 8 which is a polynomial with the same variable and exponent.
Angle EMG is equal to 120 degrees. The measure of angle EMF is 60 degrees.
What is the measure of angle FMG?
Trapezoid EFGH is given. M is the midpoint of side GH. Points E and F are joined to M to form 3 equal triangles EHM, EMF and MFG.
Answer:
[tex]\angle FMG=60^{\circ}[/tex]
Step-by-step explanation:
Given: [tex]\angle EMG=120^{\circ}\,,\,\angle EMF=60^{\circ}[/tex]
To find: [tex]\angle FMG[/tex]
Solution:
A trapezoid is a quadrilateral in which one pair of opposite sides is parallel. A trapezoid in which opposite angles are supplementary is known as an isosceles trapezoid. In any isosceles trapezoid, two opposite sides are parallel, and the two other sides are equal to each other.
Consider the figure:
[tex]\angle FMG=\angle EMG-\angle EMF\\=120^{\circ}-60^{\circ}\\=60^{\circ}[/tex]
Find the area of a triangle, two sides of which are 10 cm and 16 cm and the perimeter is 38 cm.
Answer:
Step-by-step explanation:
third side=38-(10+16)=38-26=12
sides are 10 cm, 12 cm , 16 cm.
2s=10+12+16=38
s=38/2=19
area=√(s(s-a)(s-b)(s-c))
=√[19(19-10)(19-12)(19-16)]
=√[19×9×7×3]
=3√391 cm²
≈59.32 cm²

In a village the number of houses and the number of flats are in the ration9:5 the number of flats and the number pf bungalows are in the ratio 10:3 there are 30 bungalows in the village. How many houses are there in the village?
Answer: 180 houses
Step-by-step explanation:
From the question, we are informed that in a village the number of houses and the number of flats are in the ratio 9:5 while the number of flats and the number of bungalows are in the ratio 10:3 and that there are 30 bungalows in the village.
Since the ratio of the number of flats and the number of bungalows are in the ratio 10:3 and there are 30 bungalows in the village, the number of flats will be:
= 10/3 × 30
= 10 × 10
= 100 flats
Since we are told that the ratio of the number of houses to the number of flats are in the ratio 9:5 and we've gotten the number of flats as 100, then the number of houses will be:
= 9/5 × 100
= 9 × 20
= 180 houses
A sales girl is paid a basic wage of $225 per week. In addition she is paid a commission of 5% on the value of goods she sells. How much commission will she be paid on sales amounting to $1,525 and what is her gross wage for the week?
Answer:
Commission = $76.25
Gross wage = $301.25
Step-by-step explanation:
First, we know her commission is 5% of her sales which means the commission she will receive is;
5% * $1525
[tex]\frac{5}{100} * 1525[/tex]
= $76.25
∴ Her total wage for the week will be;
$225 + $76.25
= $301.25
a carpenter can make 30 chairs, 25 tables and 15 beds in a month. what proportion of the carpenter's output is bed.
Answer:
3/14
Step-by-step explanation:
Express the beds as a fraction of the total output.
Beds = 15
Total output = 30 + 25 + 15 = 70
Proportion that is beds = 15/70
15/70 = 3/14

What is the slope of the line through the points (0,0) and (2,6)
Answer:
3
Step-by-step explanation:
The slope of a line can be found by dividing the amount that the line "rises" over a certain amount of "run". In this case, the line rises 6 units while moving 2 units to the right. 6/2=3, meaning that the slope of this line is 3. Hope this helps!
Round to the nearest hundredth : 8.113
plz help :)
Answer:
[tex]8.11[/tex]
Step-by-step explanation:
Rounded to nearest hundredth.
After Round to the nearest hundredth value of number is,
⇒ 8.11
We have to given that;
A number is,

And, We an Round to the nearest hundredth.
Since, Rounding numbers refers to changing a number's digits such that it approximates a value.
Here, In number 8.113,
Digit in thousandth place is 3 which is less thn 5.
Hence, After Round to the nearest hundredth value of number is,

For f(x) = 2x + 1 and g(x) = x^2- 7, find (f - g)(x). ?
Answer:
(f-g)(x)=-x^(2)+2x+8
the solutions are:
x=4 or x=-2
Step-by-step explanation:
(f-g)(x)=2x+1-(x^(2)-7)
(f-g)(x)=-x^(2)+2x+1+7
(f-g)(x)=-x^(2)+2x+8
does this help or should I solve for the zeros/solutions of this quadratic equation?
then:
-x^(2)+2x+8=0
-(x^(2)-2x-8)=0
x^(2)-2x-8=0
(x-4)(x+2)=0
x=4 or x=-2
Answer:
The required answer is: -x^2+2x+8
Step-by-step explanation:
We have been given the two function:
f(x)=2x+1
And g(x)=x^2-7
We have to find (f-g)(x):
(f-g)(x)=f(x)-g(x)
(2x+1)-(x^2-7)
2x+1-x^2+7
-x^2+2x+8
Hence, the required answer is: -x^2+2x+8

John, Peter and Mary shared a sum of
money in the ratio 2:4:9. John and Peter
together received $360. How much money
in all was shared?
(A) $480
(B) $540
(C) $600
(D) $900
Answer:
D
Step-by-step explanation:
Here, we want to know the total amount of money shared
Total ratio is 2 + 4 + 9 = 15
Now, John and Peter with ratios 2 and 4 equals $360
If we combine their ratios, what we have would be
6:9
Let the amount shared be x
Now, mathematically
6/15 * x = 360
6x = 15 * 360
x = (15 * 360)/6
x = $900
3x+4=3x+4
what is x?

A force of 76 N is applied to an area of 490 cm2. Calculate the pressure in N/m2. Give your answer to the nearest integer.
Answer:
Given
Hope it helps
Step-by-step explanation:
Pressure is the force per unit perpendicular area over which the force is applied
p=F/A
Where f is force and a is area
So P
= F/A
= 76N / 0.049m2
= (76/0.049) Nm2
= 76000/49
= 1551.02
Or 1551 N/m2
Given the functions below, find (f - g) (2).
f(x)
x2 + 3
g(x) = 4x – 3
=
Answer:
(f - g)(2) = 2
Step-by-step explanation:
Given the functions below, find (f - g) (2).
f(x) = x² + 3
g(x) = 4x – 3
(f - g)(x) = (x²+3)-(4x-3)
(f - g)(x) = x²+3-4x+3
(f - g)(x) = x²-4x+6
(f - g)(2) = (2)²-4(2)+6
(f - g)(2) = 4-8+6
(f - g)(2) = 2
