To the nearest pound Jon has £9 to the nearest 50p Ellie has £6.50 work out the possible total amount of money
Answer:
£16.25
Step-by-step explanation:
Jon. £9 to nearest pound so £9.50
Ellie. £6.50 to the nearest 50p so £6.75. £
9.5+6.75 = £16.25
From what we know about rounding, we will see that the possible total amount of money is given by the inequality:
£14.75 ≤ M ≤ £16.23
How does rounding works?When we round a given number to a given place, what we need to do is look at the number at the right of that place.
If the number is 5 or larger, we round up.If the number is 4 or smaller, we round down.So we know that Jon, to the nearest pound has £9.
This means that he can have a minimum of £8.50And a maximum of £9.49We know that to the nearest £0.50, so we look at the half of 0.5, which is 0.25, for example:
1.23 would be rounded to 1.
1.25 would be rounded to 1.50
1.27 would be rounded to 1.50
Ellie has £6.50, then she has:
A minimum of £6.25A maximum of £6.74So, adding the minimums and maximums together we get:
minimum = £8.50 + £6.25 = £14.75
maximum = £9.49 + £6.54 = £16.23
So the possible total amount of money, defined by M, is in the interval:
£14.75 ≤ M ≤ £16.23

What is the value of X plz help
Answer:
x = 16
Step-by-step explanation:
(5x + 12)° + (6x - 8)° = 180°
(5x + 12 + 6x - 8)° = 180°
(11x + 4)° = 180°
11x + 4 = 180
11x = 180- 4
11x = 176
x = 176/11
x = 16

Hi someone plz explain what the distributive property is
Answer:
its hard to explain as a simple answer but i can explain w an example
Step-by-step explanation:
lets say the equation is 2 (3×5), rather than using pemdas and doing 3×5 fist, you take the 2 amd multiply it by the numbers in the paranthesis, so, do that snd u get 2×3 which equals 6 and then u do 2×5 which equals 10 so the equation in the end should be 6+10 which equals 16, and obviously if u use pemdas u would gey a different answer (the answer if u use pemdas is 30)

The latitude value of Liverpool is 53.41 degrees, and the longitude value is -2.99 degrees. The latitude value of Melbourne is -37.81 degrees, and the longitude value is 144.96 degrees. The two cities are (15.6, 50.42, 56.4, 91.22, 91.55, 107.15)
degrees apart in latitude. The two cities are (50.42, 91.22, 91.55, 107.15, 141.97, 147.95) degrees apart in longitude.
Answer:
the difference in latitude is 91.22°
the difference in longitude is 147.95°
Step-by-step explanation:
For Liverpool, London. The latitude is 53.41°, longitude is -2.99°
For Melbourne, Australia. The latitude is -37.81°, longitude is 144.96°
The negative or positive magnitude of their values shows their position on either sides of the origin of the latitude (equator) and the origin of the longitude (prime meridian).
The latitude measures the relative position of a point, north or south of the equator (latitude 0°). The longitude measures the relative position, east or west of the prime meridian (longitude 0°)
the difference in latitude is 53.41° - (-37.81°) = 53.41° + 37.81° = 91.22°
the difference in longitude = 144.96° - (-2.99°) = 144.96 + 2.99 = 147.95°

A 20-oz bottle of soda is $1.79. A 32-oz bottle is $3.49. Which has the lower unit cost?
Answer:
The first bottle has the lowest unit rate.
Step-by-step explanation:
To find the unit rate we need to divide the price by the amount there is.
1.79 / 20= 0.0895
3.49 / 32= 0.1090625
After doing this, we can confirm that the first bottle has the lowest unit rate because it has the lesser number.
Hope this helped! If it did please consider making this the brainliest! :)
The first thing that you do is divide each cost by the number of ounces and round your answer to the nearest tenth
3.49/32=.109 or 10 cents per ounce
1.79/20=.089 or 9 cents per ounce
so 9 cents per ounce is cheaper than 10 cents per ounce
the answer is a 20 oz bottle for $1.79
