12.5 /9=1.39

2.5/1.83=1.37

The super market has a better value.

Answer:

The farm sells potatoes at a better price than the supermarket potatoes.

Step-by-step explanation:

So, first we have to get the potatoes to the same exact weight. So we divide the 12.5kg by 5 and then we get 2.5kg, which is the same as the supermarket potatoes. But then, since we divided the weight, now we have to divide the amount of euros by five, and then we get 1.80. So that means that at the farm shop, for every 2.5kg, you pay £1.80 for 2.5kg, which is £0.03 less that the supermarket potatoes.

Let g be the function given by g(x)=-3x^2-2x+3 evaluate g(-2)
sashaice [31]

g(x) = -3x² - 2x + 3

g(-2) = -3(-2)² - 2(-2) + 3

g(-2) = -12 + 4 + 3 = -5

Three numbers have a mean of 64. When a fourth number is included the mean is doubled. What is the fourth number?
astra-53 [7]
The mean is calculated by adding up all of the given numbers and dividing by the number of numbers.

Lets, for ease of understanding, say that the first three number were 64...

Mean=(64+64+64)/3=192/3=64

Now, lets solve for the mean where 'x' is the unknown fourth number and 128 is the mean. (since, the answer said that when the fourth number was added the mean, 64, was doubled '64*2=128')

128=(64+64+64+x)/4
128=(192+x)/4
Multiply both sides by 4
512=192+x
subtract 192 from both sides
320=x

The missing number is 320..


Now lets double check our work.

Mean=(64+64+64+320)/4=512/4=128

Answer=320

What is the orthocenter of a triangle with vertices A(−3,−2)A(−3,−2), B(−2,2)B(−2,2), and C(2,−2)C(2,−2)?
ExtremeBDS [4]

A(−3,−2), B(−2,2), C(2,−2)

The orthocenter is the meet of the altitudes. We see AC is parallel to the x axis so the perpendicular x=-2 is the altitude through B.

Between A and B we have slope (2 - -2)/(-2 - -3) = 4 so perpendicular slope -1/4 through C(2,-2):

y+2 = -\frac 1 4 (x - 2)

For the y coordinate of the orthocenter we substitute in x=-2.

y+2 = -\frac 1 4(-2 - 2) = 1

y = -1

So the orthocenter is (x,y)=(-2,-1)

Answer: (-2,-1)
