Stuart owns a window washing business. He can wash the windows on 9 houses in 4 hours. At this rate, how long would it take him to wash the windows on 45 houses? How many houses could he wash in 12 hours?
Answer:
20 Hours = 45 Houses
27 = 12 Hours
Step-by-step explanation:
The time taken to wash 45 houses is 20 hours and the number of houses in 12 hours is 27.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Stuart owns a window-washing business. He can wash the windows on 9 houses in 4 hours.
The time taken to wash 45 houses is,
9 houses = 4 hours
1 house = 4 / 9 hours
45 houses = ( 45 x 4 ) / 9 hours
45 houses = 20 hours
The number of houses in 12 hours,
4 hours = 9 houses
1 hour = 9 / 4 houses
12 hours = ( 9 x 12 ) / 4 houses
12 hours = 27 houses
Therefore, the time taken to wash 45 houses is 20 hours and the number of houses in 12 hours is 27.

area=m2
(round to the neerest 100)
Answer:
22.33 m²
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 8 m
Angle sustained (θ) = 40°
Pi (π) = 3.14
Area of small sector (A) =?
The area of the small sector can be obtained as illustrated below:
A = θ/360 × πr²
A = 40/360 × 3.14 × 8²
A = 40/360 × 3.14 × 64
A = 22.33 m²
Therefore, the area of the small sector is 22.33 m²

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

On selling 250 cascades, a man had an equal gain to the selling price of 25 cascades. Find his gain percent
Answer:
11.11%
Step-by-step explanation:
The selling price is 250
The cost price is 250-25
= 225
Therefore the gain can be calculated as follows
=250-225x/225x×100
1/9 ×100
= 0.1111×100
= 11.11%
Hence the gain is 11.11%

The option which is not a factor of the cubic equation is (x+4)
What are cubic equations?The algebraic equations having variables with power 3 are referred to as cubic equations. A generalized form of a cubic equation is ax³+ bx²+ cx + d = 0.
Given here: The cubic function f(x)=x³-12x²+44x-48
Clearly in the options the list of factors are -4,6,2,4
Checking for all 4 options we get
f(-4)=-4³-12×4²+44×(-4)-48
=-64-192-176-48≠0
f(6)=6³-12×6²+44×(6)-48
=216-12×36+264-48
=0
f(2)=2³-12×4+44×2-48
=8-48+88-48
=0
Similarly we can find for x=4 that f(4)=0
Hence, The option which is not a factor of the cubic equation is (x+4)
