Adam has 16.45 kg of flour, and the uses 6.4 to make hot cross buns. The remaining flour is exactly enough to make 15 batches of
White raven [17]

Answer: 0.6kg of flour will be in each batch of scones.

Step-by-step explanation:

Adam has 16.45 kg of flour, and he used 6.4kg to make hot cross buns. This means that the remaining flour would be the total amount of flour that he had initially minus the the amount that he used to make hot cross buns. This is expressed as

16.5 - 6.4 = 10.05 kg

The remaining flour is exactly enough to make 15 batches of scones. This means that 10.05 kg of flour will be enough to make 15 batches of scones.

We want to determine how much flour, in kg, will be in each batch of scones. Let this amount of flour be xkg

If 10.05 kg of flour will be used to make 15 batches of scones. Then,

xkg of flour will be used to make 1 batch if stones

x = 10.05/15

x = 0.67

What is 2 times 3 times n times n = 54
kolezko [41]

If I'm reading this correctly, it is 2*3*n*n = 6n^2

6n^2 = 54  Divide by 6

n^2 = 54/6

n^2 =  9      Take the square root of both sides.

sqrt(n^2) = sqrt(9)

n = +/- 3

n = + 3 or n = -3. Both will solve the equation above.

Edit

2 * 3 * n * n

Let n = 3

2 * 3 * 3 * 3 = 6 * 9 = 54

The other value is n = - 2

2 * 3 * n * n

2 * 3 * (-3) * (-3)   A minus times a minus is a plus.

2 * 3 * 9 = 6 * 9 = 54

both + 3 and - 3 for n will give 54.

Help Please.Use complete sentences to explain the steps required in converting 180 degrees to its equivalent radian measure. Inc
Phoenix [80]
To convert 180 degrees to its equivalent radian measure, multiply it with π/180.
180 (π/180)
The result is π radians.
This is also how the other angles in degrees are converted to radians. Simply multiply with π/180 and express the result in terms of pi.<span />
