Answer: the plain pencil costs 10 cents and the colored pencil costs 20 cents
Only 4 because result is (x-4)(x-4) that means (x-4)^2=0
So
X-4=0
X=4
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
Answer:
274878070200
Step-by-step explanation:
4 to the power 11 = 4194304
4 to the power -8 = 0.00001525878
4194304/0.00001525878 = 274878070200
Answer:
Options A and D are correct.
Step-by-step explanation:
The cost y (in dollars) for x ounces of peanuts is represented by the equation
.... (1)
It means the cost of each ounce of peanuts is $0.23.
The cost y (in dollars) for x ounces of pecans is represented by the equation
.... (2)
It means the cost of each ounce of pecans is $0.45.
$0.45 > $0.23
It means the cost for pecans is greater than the cost of peanuts. Option B is incorrect.
The cost for peanuts is $0.22 per ounce less than the cost for pecans. Option A is correct.
Substitute x=8 in equation (1).
The cost for 8 ounces of peanuts is $1.84. Option C is incorrect.
Substitute x=8 in equation (2).
he cost for 8 ounces of pecans is $3.60.. Option D is correct.
