Answer: the sand in the new terrarium is 2 inches deep.
Step-by-step explanation:
Zach has a terrarium with the dimensions of 20 by 8 and the terrarium was filled with 3 inches of sand. It means that the volume of sand that this terrarium contains is
20 × 8 × 3 = 480 inches³
Zach gets a new terrarium that is larger with the dimensions of 10 by 24. If Zach moved the existing sand in the new terrarium and the height of the sand is represented by h, then the volume of sand into he new terrarium is
10 × 24 × h = 240h
Since the volume of sand in both terrariums is equal, then
240h = 480
h = 480/240
h = 2 inches
Answer:
x+x+30 is the required expression.
Step-by-step explanation:
You watch x minutes of television on Monday
An since, the same amount on Wednesday that means x minutes on Wednesday
And 30 minutes on Friday
Since, we have to tell the expression that represents the total amount in the given situation that means
x+x+30 is the required expression.
Answer:
114 feet
Step-by-step explanation:
the black and white will both have the same area. and given that each path is 1 ft wide and initially 12 ft long we can slowly determine the area.
x times 1 will still equal x
12(1) still equals 12 so we can just write it as 12.
12+12+11+11+10+10+9+9+8+8+7+7= 114
where I came up with this? there are a total of 12 sides if you follow the black path. and by every 2 sides the path gets shorter by 1 foot.
the white side also has 12 sides if you look. therefore both the black and the white part of the shape will have an area of 114.
Answer:
213.333 ounces
Step-by-step explanation:
A small office purchases bottled drinking water. The water comes in containers that hold 5 gallons. Two-thirds of the office container was drained last week to put out a fire in the wastebasket.
a. How much water (in ounces) is left in the container?
b. How many 12-ounce glasses can be filled with the water that remains in the container
Container = 5 gallons
Two-thirds was drained last week to put out a fire in the wastebasket
That is 2/3 of 5
= 2/3 × 5
= 10 / 3 gallons
Water left in the container = 5 - 10/3
= 15-10/3
= 5/3 gallons
Convert 5/3 gallons to ounces
5/3 gallons = 213.333 ounces
B. Number of 12 ounces glass that can be filled from the water left in the container = 213.333 ounces / 12
= 17.77775
Approximately 18
