Answer:
£152.
Step-by-step explanation:
We have been given that a bottle contains 255 coins. 1/3 of the coins are £1.00.
Let us find 1/3 of 255 to find the number of £1 coins.
This means we have £85.
We are also told that 110 of the coins are 50 p coins.
Let us figure out number of 20 p coins by subtracting the number of £1 coins and 50 p coins from 255.
Now let us find total value of the coins contained in the bottle by adding the values of £1 coins, 50 p coins and 20 p coins.
Therefore, the total value of the coins contained in the bottle is £152.
Answer:
42 is your answer if there is -5x
Step-by-step explanation:
when x=-4
x²-5x+6=(-4)²-5×-4+6=16+20+6=42
3/4+2/6+1/2 = 9/12+4/12+6/12 = 19/12 Brendan has 1 7/12 leftover pizzas. THis is achieved by multiplying for a common denominator and adding
19/12-2/3 = 19/12-8/12 = 11/12 Brendan has 11/12 more pizzas than Steve.
Answer:
cosine
Step-by-step explanation:
fundamental trigonometric identities
We have a right triangle with a 15m hypotenuse and a 8m leg. If we use x for the missing leg then the Pythagorean Theorem states that:
Then we have to solve that equation for x:
![\begin{gathered} x^2=15^2-8^2=225-64 \\ x^2=161 \\ x=\sqrt[]{161} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%5E2%3D15%5E2-8%5E2%3D225-64%20%5C%5C%20x%5E2%3D161%20%5C%5C%20x%3D%5Csqrt%5B%5D%7B161%7D%20%5Cend%7Bgathered%7D)
So the answer is the square root of 161.
