Formula: Volume = BH

Base = 8in Height = 5in Width = 3.25in

Answer:

130 cubic inches

Step-by-step explanation:

length × width × height.

Look in the last row, and at the last item in that row.

The last row shows a stem of 5. The last item in that bottom row is 6, so the leaf here is 6.

A stem of 5 and a leaf of 6 combine to get the value 56 according to what the key shows. Therefore 56 is the largest value.

The greatest number of cans collected is 56.

Stem and leaf plot is a method of portraiting data where each data point is divided in to a stem part and a leaf part.

Stem part consists of the first digits and the leaf part consists of the last digits.

Given a stem and leaf plot.

Using the digits, the data points in each row are,

33, 33, 36, 36, 38, 39

42, 42, 44, 45, 45, 45, 46

51, 53, 54, 54, 56

Find the greatest data point from the set, which is the greatest number of cans collected.

Greatest data point is 56.

Hence 56 is the greatest number of cans collected by the students.

Answer:

72 cm³

Step-by-step explanation:

We can use the formula for a triangle prism's volume to solve.

V = [tex]\frac{B*H*L}{2}[/tex]

-> B is the base, H is the height, L is the length

-> Think of the area of a triangle. It is the same formula, but we also multiply by the length.

V = [tex]\frac{B*H*L}{2}[/tex]

V = [tex]\frac{3*4*12}{2}[/tex]

V = [tex]\frac{144}{2}[/tex]

Step-by-step explanation:

If it takes 25 minutes for 1/6 to be filled, then 25 minutes = 1/6 of the pool

To fill the pool then we need to find 6/6

25 x 6 = 150 so that is how much water is in the pool when it is full

150 - 25 minutes, because 1/6 is already full, means it takes 125 minutes longer.

3. b= 5

4. d= -5

5. z= 2/3

Step-by-step explanation:

3) 5b-3=22

   5b=25     add 3 to both sides

   b= 5        divide 5 from both sides

4) 1.5d+3=-4.5

   1.5d=-7.5    subtract 3 from both sides

   d=-5           divide 1.5 from both sides

5) 4=9z-2

   6=9z       add 2 to both sides

   6/9=z      divide 9 from both sides

   2/3=z      simplify

Answer:

68

Step-by-step explanation:

The 22-degree angle plus angle x is equal to the right angle opposite of it. A right angle is equal to 90 degrees. Therefore, we know that 22 + x = 90.

22 + x (- 22) = 90 (- 22)

x = 68

Therefore, angle x equals 68 degrees.

Answer:

I believe your answer would be 1794

Step-by-step explanation:

2600 - 806 = 1794

To check:

1796 (St) + 806 (chairs left) = 2600 (total chairs)

So I would think the answer is 1794

The 69% of the seats in the theatre were filled by the 6th graders on the trip if a theatre that has 2600 seats.

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Total seats = 2600

The students left 806 seats vacant.

Number of students(occupied seats = 2600 – 806 = 1794

A percentage of the seats in the theatre were filled by the 6th graders on the trip:

= (1794/2600)×100

= 0.69×100

= 69%

Thus, the 69% of the seats in the theatre were filled by the 6th graders on the trip if a theatre that has 2600 seats.
