A yogurt costs 55 pence . how many yogurts can be bought for 3 pounds
Answers
3/0.55=?
if we multiply both numbers by 100, so that there are no fractions, we have:
300/55=5 and 25 cents left
(check: 5*55=275)
so the correct answer is 5 yoghurts.
The best way to do this is:
Convert 3.00 to pence
3.00 = 300p
Then keep adding 55p to itself to work out how much 1 yoghurt is, 2 then 3 etc.
1 yoghurt = 55p
2 yoghurts = 110p
3 yoghurts = 165p
4 yoghurts = 220p
5 yoghurts = 275p
6 yoghurts = 330p
Okay, now 330p is 3.30 which is more than 3.00, which means that there isn't enough money for 6, but there is for 5.
EXTENSION:
To work out how much would be left over:
300 - 275 = 25p

Answer:
x = - 3, x =
Step-by-step explanation:
Given
f(x) = 4x² + 5x - 21
To obtain the zeros, equate f(x) to zero, that is
4x² + 5x - 21 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 4 × - 21 = - 84 and sum = + 5
The factors are + 12 and - 7
Use these factors to split the x- term
4x² + 12x - 7x - 21 = 0 ( factor the first/second and third/fourth terms )
4x(x + 3) - 7(x + 3) = 0 ← factor out (x + 3) from each term
(x + 3)(4x - 7) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
4x - 7 = 0 ⇒ 4x = 7 ⇒ x =
Final answer:
You can find the zeros of the function f(x) = 4x² + 5x - 21 by setting the function equal to zero and solving for x using the quadratic formula. Upon solving, you get the zeros as -7/4 and 3.
Explanation:
To find the zeros of the quadratic function f(x) = 4x² + 5x - 21, you need to set the function equal to zero and solve for x. This means solving the equation 4x2 + 5x - 21 = 0. This is a quadratic equation that can be solved using the quadratic formula, x = [-b ± √(b² - 4ac)] / (2a).
Here, a = 4, b = 5, and c = -21. Substituting these values into the quadratic formula gives us x = [-5 ± √((5)² - 4*4*(-21))] / (2*4). Simplifying yields x = {-7/4, 3}.

Another method to get the lentgth of two sides:
By looking at the coordinates you can see that (-5,2) and (7,2) gives one side, which is 12 long (the length from -5 to 7) and (7,2), (7,-3) gives another side, which has a length of 5 (from 2 to -3). Use the Pythagorean theorem to get the last side:
5^2 + 12^2 = x^2
25 + 144 = x^2
169 = x^2
13 = x
You need the perimeter so simply add all the sides together: 12+5+13= 30
