Say you are at a grocery store and find an item without a listed unit price. How would you calculate the unit price for this ite
Aneli [31]

Answer:

Unitary Method

Step-by-step explanation:

If the item is not listed with the unit price we can use different methods to calculate its unit price.

Unit price tells us the cost of each pound, ounce or gram, square foot or meter, etc., of the product.

We can use Unitary Method to calculate the price of each unit. The unitary method is a technique which is used for solving a problem by calculating the value of a single unit, i.e. 1 unit (by dividing) and then finding the necessary value by multiplying the single unit value.

For an instance if a bag of 6 pounds of potato says $7.00, to figure out the price of each pound (that is 1 unit) of potato we can use unitary method:

6 pounds costs $7.00

1 pound costs: \frac{7}{6}=1.17 dollars.

And that is how we calculate the price of each unit.

What is the slope of the line through (-9,6)(−9,6)(, minus, 9, comma, 6, )and (-3,9)(−3,9)(, minus, 3, comma, 9, )?
Diano4ka-milaya [45]

Answer:

0.5

Step-by-step explanation:

The slope m of a linear equation y = mx + b that goes through point (-9,6) and point (-3, 9) would have the following formula

m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{9 - 6}{-3 - (-9)} = \frac{3}{6}= \frac{1}{2} or 0.5

Where (x_1,y_1), (x_2, y_2) are the coordinates of the 2 points that this line goes through

EMERGENCYYYY TEST CLOSES SOON AND IM BARELY DONE!!!!!please do part 1 and 2
irakobra [83]

Answer:

Part A: Options D and E

Part B: Disagree

Step-by-step explanation:

Part A:

From the graph attached,

Option A

The object is launched from the ground.

False.

Since, the object is launched from the 5 feet above the ground.

Option B

The flight is symmetric about the line t = 10

False.

Since, the flight is symmetric about the line t = 12

Option C

The object reaches a maximum height of 12 feet.

False.

At t = 12 seconds maximum height of the object = 19.4 feet

Option D

The object is flying in the air during the interval 0 < t < 25.93

True.

Option E

The object reaches its maximum height after 12 seconds of flight.

True.

After 12 seconds object is at the maximum height 19.4 feet.

Therefore, Options D and E are the correct options.

Part B:

From the table attached,

h(4) = 13

h(20) = 13

At t = 4 and 13 seconds height of the object is same.

h(4) = h(20)

But Timothy said h(4) < h(20)

Therefore, disagree with the statement of Timothy.
