A rectangular prism has a length of 84 inches, a width of 5 inches, and a height of 2 inches. Oscar has a storage container for the
prism that has a volume of 100 cubic inches.
What is the difference in volume between the prism and the storage container?
Enter your answer in the box as a simplified mixed number or a decimal.
in

Answers

The rectangular prism’s volume would need to be calculated.

Volume = length * width * height

Volume = 84 * 5 * 2

Volume = 840

The difference needs to be subtracted

840 - 100 = 740

740

Matt’s gym charges more to reserve the basketball court.

To determine Matt’s cost of reserving the court, look for the difference between the mostly cost each time the court is reserved another time.

The cost of reserving the court one time is: $52.75.

The cost of reserving the court two times is: $55.50.

$55.50 - $52.75 = $2.75, therefore the cost of reserving the court is $2.75.



However it’s important to check your work to make sure that the cost increases by a constant amount. Check the difference between each time the court is reserved another time.

The cost of reserving the court two times is: $55.50.

The cost of reserving the court three times is: $58.25.

$58.25 - $55.50 = $2.75. The cost of reserving the court for a third time is an additional $2.75.

Finally, The cost of reserving the court three times is: $58.25.

The cost of reserving the count a forth time is $61.

$61 - $58.25 = $2.75, therefore the incremental cost of reserving the cost a forth time is $2.75.

Based on the information, Matt’s gym charges $2.75 every time he wants to reserve a court, whereas Tyrell’s gym only charges him $2.00, therefore Matt’s gym charges more.


Yesenia has a 13 ft ladder that she placed against a
wall. How far up the wall will the ladder reach when the
base of the ladder is 5 ft from the wall?

Answers

Answer:

12 ft

Step-by-step explanation:

Using formula (pythagorean theorem)

a² + b² = c²

Where :

13 = c

and 5 = a

5² + b² = 13²

25 + b² = 169

169 - 25 = b²

144 = b²

Sq root b = 12

It will reach up 12 ft.

On the line that passes through point C, mark a point D that is distinct from point C. Use the slope formula along with coordinates of points to find the slopes of and . Show your work.

Answers

Answer:

PLATO

Step-by-step explanation:

Answer:

The coordinates of point D will vary based on the point location, but the resulting slope of the line through points C and D will be the same.

A  =  (-3, 3), B = (-1,-1)

Slope of AB  =  (YB−YA) / ( XB –XA) =−1−3 / −1−(−3)= − 4 / 2= −2

D =  (-1,6), C = (1,2)

Slope of DC  =  (YC−YD) / (XC−XD)= 2 – 6 / 1−(−1)=−4 / 2=−2

The boy might serve as a type of Italy: lovely and smiling, and yet suffering. He was hungry and thirsty, but no one gave him anything; and when it became dark and they were about to close the gardens, the porter turned him out. A long time he stood musing on the bridge which crosses the Arno and looking at the glittering stars that were reflected in the water which flowed between him and the wonderful marble bridge Delia Trinit. He then walked away towards the Metal Pig, half knelt down, clasped it with his arms, and, putting his mouth to the shining snout, drank deep draughts of the fresh water. Close by lay a few salad leaves and two chestnuts, which were to serve for his supper. No one was in the street but himself. It belonged only to him. He boldly seated himself on the pig's back, leaned forward so that his curly head could rest on the head of the animal, and, before he was aware, fell asleep. It was midnight. The Metal Pig raised himself gently, and the boy heard him say quite distinctly, "Hold tight, little boy, for I am going to run"; and away he started for a most wonderful ride.
