Can u give me thanks I need it so I can get 50 points plz
I find that fractions can be tricky, so I convert them to decimals before subtracting.
3 3/4 = 3.75
7/8 = 0.875
3.75 - 0.875 = 2.875
Knowing that 0.875 = 7/8, we now know that our answer is 2 7/8.
Hope this helps!
Answer:
To make 65 chocolate drinks, she needs:
12 g of chocolate powder and 5 marshmallows per drink.
Then she needs:
12g*65 = 780 grams of chocolate powder.
We know that the chocolate powder comes in jars of 250g, such that each one costs £2.99
If she buys 3 jars, she will have: 3*250g = 750g
So she will not have enough, then she needs to buy 4 jars.
Then in chocolate powder, she will pay 4 times £2.99 = £11.96
And for marshmallows, she needs:
65*5 = 325 in total.
Marshmallows come in bags of 120, then the number of packs that Abi needs to buy is:
325/120 = 2.7
That should be rounded up (because she can not buy a 0.7 of a bag)
Then she needs 3 bags, and each bag costs £1.45
Then the total cost in marshmallows is 3*£1.45 = £4.35
Answer:
Step-by-step explanation:
The key to solving this problem lies in understanding that the domain of the square root function includes ONLY zero or positive numbers.
In this case, we set 4x - 3 ≥ 0.
Solving for 4x: 4x ≥ 3. Therefore, x ≥ 3/4.
The domain of the given function is [3/4, ∞ ).
