Food Mart and Jan’s Store sell boxes of the same type of breakfast cereal.
Each shop has a special offer.
food mart has 400 g, 20% off the normal price of £5
jans store 400 g plus 30% extra £5
Which box of cereal is the better value for money?
You must show your working
someone help pleaseee
Answer:
The box of cereal bought at Farm store is a better value for money
Step-by-step explanation:
To answer this question question, we will need to be making a comparison. The comparison i will like to make with the two offers is price per grammes ( £/g). The offer with a better price or higher price per grammes win.
Let’s proceed!
For the food mart,
we are paying 20% off £5 for 400g
let’s calculate 20% off £5
That would be 5-(20/100 * 5) = 5-1 = £4
The price per grammes here is £4/400g = £0.01/g
For Jans store ;
we have 400g plus 30% extra at £5
What we need do here is to first calculate 30% extra of 400g
Mathematically, that would be 30/100 * 400 = 120
Total grammes here is 120 + 400 = 520g
Price per grammes here would be ; £5/520g = £0.00962/g
This is lesser than what we have at Food mart as 0.01 > 0.0096

How many solutions does this equation have?
–n − 5 = –n
Answer:
0
Step-by-step explanation:
-n+n-5 = 0
-5 = 0
Answer:
no solutions
Step-by-step explanation:
–n − 5 = –n
Add n to each side
–n+n − 5 = –n+n
-5 = 0
This is never true so there are no solutions
Lexi runs a race at school. She runs at a rate of 4 miles per hour for the first mile, then increases her rate to 5 miles per hour until the last mile when she runs 6 miles per hour. Which equation below represents her time, T. In hours, If she runs a total of x miles
Answer:
60T = 12x - 1
Step-by-step explanation:
In speed distance and time, time(t) is given by
time = distance(d)/speed(s)
total distance ran = x miles
case 1
d = 1 mile
speed = 4 miles per hour
as time = distance(d)/speed(s)
t = 1/4
____________________________
case 2
speed = 5 miles per hour
it is given that out of x miles for first mile and last mile her speed was 5 miles per hour
thus distance for this speed can be calculated by
subtracting first and last mile from x miles
therefore
distance = x-2 miles\
t = (x-2)/5
_____________________________________
case 3
distance = 1 mile
speed = 6 miles per hour
t = 1/6
______________________________
Total time T as required will be sum of time for the 3 case calculated above
T = 1/4 + (x-2)/5 + 1/6
T = 1/4 + (x - 2)/5 + 1/6 (taking LCM of 6,5,4 as 60 and solving)
T = (15 + 12x - 24 + 10)/60
T = (12x - 1)/60
60T = 12x - 1
Thus, equation 60T = 12x - 1 represents her time T

A circle has a radius of square root 131 units and is centered at (0,-4.3).
Whats the equation of this circle?
Answer:
x^2 + (y + 4.3)^2 = 131
Step-by-step explanation:
The basic equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2. Here the center is (0, -4.3) and the radius is √131. Substituting as indicated, we get:
(x - 0)^2 + (y + 4.3)^2 = 131, or
x^2 + (y + 4.3)^2 = 131
The length of an arc of a circle is 9.42cm. If the diameter of the circle is 10cm, find the angle subtended by the arc at the center of the circle. (Take π = 3.142)
SHOW ALL WORKING.
Answer:
1.89 radians or 108 degrees.
Step-by-step explanation:
Circumference of the circle = 10 * 3.142
= 31.42.
So 31.42 is equivalent to 2 pi radians, so:
Angle subtended at the center
= (9.42 / 31.42) * 2 pi
= (9.42 / 31.42) * 2 * 3.142
= 1.89 radians or 108 degrees..
