Answer:

0.85

Step-by-step explanation:

The correct answer is: 0.85 that is 85%

This test can determine your cardiovascular fitness by performing a one mile walk as fast as the individual can. Once the mile is completed, heart rate is taken.  

The formula used to calculate VO2max is:

132.853 - (0.0769 × Weight) - (0.3877 × Age) + (6.315 × Gender) - (3.2649 × Time) - (0.1565 × Heart rate)

Weight is in pounds (lbs)

Gender Male = 1 and Female = 0

Time is expressed in minutes and 100ths of minutes

Heart rate is in beats/minute

Age is in years

Mr. Hershman has purchased a farm that is in the shape of a rectangle. The dimensions of the piece of land are 4.74.7 km by 2.58
Gre4nikov [31]

Answer:

Area in square kilometers equals 12.126km^{2}

Area in hectares equals 1212.6 hectares

Step-by-step explanation:

We know that area of rectangle is length times the breadth.

Using the given values we have

Area=length\times breadth\\\\\therefore Area =4.7km\times 2.58km\\\\Area=12.126km^{2}

Thus he bought land of area 12.126km^{2}

We know that 1 hectare =0.01km^{2}

Thus 12.126km^{2} = 12.126/0.01 hectares

Area in hectares equals 1212.6 hectares

The formula for the area of a triangle is A=12bh , where b is the base of the triangle and h is the height of the triangle. What
Delvig [45]
If the formula is A = 1/2 * b * h and we know that A = 22 and h = 8, then we can write it down as:

22 = 1/2 * b * 8
22 = 1/2 * 8b
22 = 4b                          / ÷ 4 (both sides)
b = 5.5

Answer: Length of the base is <span><u>5.5 cm</u></span><u />.

Doublecheck:

1/2 * 5.5 * 8 =
= 2.75 * 8 =
= 22

Correct :)

Box D and Box E are made from unit cubes of the same size.
Dominik [7]

Answer:

Box E has a greater volume than Box D.

Step-by-step explanation:

Step 1 : Find the volume of Box D.

The formula for volume of a rectangular prism such as this is

height * width * depth

Knowing this, let's substitute the values.

3 * 5 * 1 = 15

The volume of box d is 15 cubic units.

Step 2 : Find the volume of Box E.

height * width * depth

4 * 4 * 1 = 16

The volume of box e is 16 cubic units. Therefore box E has a greater volume than box D.
