Answer:
3.24kg
Step-by-step explanation:
The proportion method will be used to find the mass of the pears.
Let "A" represent the unknown mass of the Apple
A/8.1=3/5
Cross multiply
A×5=8.1×3
5A= 24.3
Divide both sides by the coefficient of A which is 5
5A/5=24.3/5
A= 4.86kg
Therefore the unknown mass of Apples is 4.86kg
To find the mass of the pear subtract the mass of Apples from the total mass
= 8.1-4.86
= 3.24kg
Thus, the farmer sells 3.24kg of pears in the market.
Perfect squares follow this pattern:
So, two terms must be perfect squares of two certain roots. If so, the remaining term must be twice their product. Let's analyse the trinomials one by one:
1) x^2 is the square of x. -64 is not a perfect square. So, the trinomial is not a perfect square.
2) 4x^2 is the square of 2x. 9 is the square of 3. The remaining term, 12x, is indeed twice their product. So, we have
3) x^2 is the square of x. 100 is the square of 10. The remaining term, 20x, is indeed twice their product. So, we have
4) x^2 is the square of x. 16 is the square of 4. The remaining term, 4x, is not twice their product (it's only the product of 4 and x, so it should be doubled). So, this trinomial is not a perfect square.
You first add all the numbers together. 17+18+15. You get 50. Then, since Jenny baked 15 cookies, (respectively) you take 15 over 50 and times it by 100 to get 30%. I’m pretty sure.
3x+2=5x-2
2x=4
x=2 i think is the answer im not sure if i got it right im sorry if i did get it wrong
Answer:
Step-by-step explanation:
Since the cost for border paper is given in terms of feet and the dimensions of the gym are given in meters, we want to convert them to the same unit. Let's choose to convert feet to meters since that would be only one conversion:
Therefore, the cost of border paper is $6.99 pet 15 feet or $6.99 pet 4.572 meters.
Since the gym is rectangular, the gym's perimeter is equal to:
Therefore, the cost of the total border paper for the gym is equal to:
