Answer: 26 feet.

Step-by-step explanation:he

The exercise is not written clearly. Assuming that it asks to find the amount of lumber (in feet) John needs for 3 shelves, let "x" represents that amount of lumber in feet.

Based on the data provided, you know that one shelf requires 8\frac{2}{3} feet of lumber.

You can convert the Mixed number to Decimal number applying these steps:

1. You must divide the numerator of the fraction by the denominator.

2. You must add the result obtained to the Whole number part.

Then you get:

8\frac{2}{3}=8+0.6667=8.6667

Knowing this, you can set up the following proportion:

\frac{8.6667}{1}=\frac{x}{3}

Finally, you must solve for "x" in order to find its value. This is:

(3)(8.6667)=x\\\\x=26.0

Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice.
In-s [12.5K]

Answer:

Beatrice's age is 34

Step-by-step explanation:

Beatruce = B

Andrew = B+2

Chris= B-3

B+(B+2) +(B-3 )= 67-B

3B-1 = 67-B

2B -1 = 67

2B= 68

B = 34

Beatrice is 34

Andrew is 36   (34+2)

Chris is 31 (34-3)

36+31 = 67

A 13 meter long cylinder with a diameter of 8 meters has a square prism with a base length of 3 meters hole going all the way th
BartSMP [9]

The volume of the solid is 626.12m³

<h3>Volume of composite solids.</h3>

The volume of the given composite solid = volume of cylinder - volume of cube

The volume of cylinder Vc = πr²h

Vc = 3.14(8/2)²(13)

Vc = 3.14(16)(13)

Vc = 653.12 m³

Similarly the volume of the cube:

Volume of cube = 3³

Volume of cube = 27 m³

Volume of the solid = 626.12m³

Hence the volume of the solid is 626.12m³
