At a garage sale, Liyah priced
her scooter for $15.50. She
ended up selling it for $10.75.
Find the percent of decrease
in the price of the scooter.
Round to the nearest tenth if
necessary
If she priced scooter for $15.50 and ended up selling it for $10.75, then the percentage of decrease in the price of the scooter is 30.64%
The initial price of the scooter = $15.50
The selling price of the scooter = $10.75
The amount decrease in the price of the scooter = Initial price of the scooter - The selling price of the scooter
= 15.50-10.75
= $4.75
The percent of decrease in the price of the scooter = (The amount decrease in the price of the scooter ÷ The initial price of the scooter)×100
= (4.75/15.50)×100
= 30.64%
Hence, if she priced scooter for $15.50 and ended up selling it for $10.75. then the percentage of decrease in the price of the scooter is 30.64%

Neil bought a house for £235 000
In the first year the value of the house depreciated by 4%
In each of years 2 and 3 the value of the house increased by 6%
Work out the value of the house at the end of year 3
Answer:
Based on the given conditions, formulate: 235000×(1+1-4%)
Calculate the sum or difference:235000×(2-0.04)
Calculate the sum or difference:235000×1.96
Calculate the product or quotient:460600
get the result:460600
So the answer is 460600
Answer:
£ 253,484.16
Step-by-step explanation:
Cost of house for first year = £235,000
Year 1
Depreciation for first year is 4% = 4/100
Depreciation in £ = 235,000 x 4/100 = £9,400
Effective value of house at end of first year
= 235000 - 9400 = £225,600
Year 2
In the second year the house value increased by 6% = 6/100
So total increase in £ at the end of year 2 with an initial value of £225,600 = £225,600 x 6/100 = £13,536
So actual value of house at end of year 2
= £225,600 + £13,536
= £239,136
Year 3
The value increased by 6% for year 3.
Value at beginning of year 3 = £239,136
Increase in value at 6% = £239,136 x 6/100 = £14,348.16
Total Value at end of year 3
= £239,136 + £14,348.16
= £253,484.16
Answer: £253,484.16
Note
Another way of quickly calculating this is noting that 4% depreciation means the new value is (1 - 4%) of initial value = 1 - 4/100 = 0.96
An increase of 6% means the new value will be 1.06 times the initial value
So the value of the house after 4% depreciation for the first year and 6% appreciation for the next 2 years
= 235000 x (0.96)(1.06)(1.06) = 253,484.16

Answer:I’m not sure what the second one is
Step-by-step explanation:
The speed of a car from point A to D is m/s however the velocity is 10 m/s due West. Calculate the speed of vehicle in m/s if it covers a distance of 1.5 km in 5 minutes.
Speed of car is 5 m/sec
What is speed?
In ordinary language and kinematics, an object's speed is defined as the magnitude of its position change over time or the magnitude of its position change per unit of time; it is therefore a scalar number. The distance traveled by an item in a time interval is divided by the duration of the period; the instantaneous speed is the limitation of the average speed as the length of time period tends to zero. Velocity is not the same as speed. Distance divided by time is the dimension of speed. The metre per second (m/s) is the SI unit of speed, while the kilometre per hour (km/h) is the usual unit.
The speed of the car = 1.5/5 km/min = 0.3 km/min
Speed in m/sec = 0.3x1000/60 = 5m/sec
Hence, speed of car = 5 m/sec

insert brackets to make the statement true 10 + 2 x 3^2 - 2 = 84
Inserting brackets to make the statement true 10 + 2 x 3^2 - 2 = 84 will be (10 + 2) × (3² - 2).
How to illustrate the informationIt should be noted that the information simply means that one had to put the bracket in the appropriate places on order to get the value of 84.
This will be illustrated thus:
= 10 + 2 × 3² - 2
= (10 + 2) × (3² - 2)

therefore it forms a right angled triangle.
given hypotenuse is 30inch
the height is 18 inches
using the Pythagorean theorem
[tex] {hypotense}^{2} = {width}^{2} + {height}^{2} [/tex]

Find the median, mode, and range.
For the given discrete data series,
Median = 4'7"
Mode = 4'8"
Range = 1'3"
To begin with, let us arrange the given discrete data series in ascending order as follows:
3'7" 3'11" 4'3" 4'6" 4'7" 4'7" 4'8" 4'8" 4'8" 4'9" 4'10"
To identify the median, locate the data point that stands exact at midpoint of the series. It is the sixth entry from left and hence median = 4'7"
To identify the mode, count and identify which data points occurs highest in frequency. 4'8" is mode as it occurs highest number of times (3 times) in the series.
To calculate the range, we subtract the last entry. Thus Range = 4'10" - 3'7" = 1'3"
