How many 4' x 8' sheets of plywood are required to cover a floor that is 9 m by 16 m?

1 answer:

8 0

Assuming no border or waste, 9m by 16 m translates to 29.52' x 52.49'.
use 32/8=4 sheets of plywood to cover the width on the 8' side.
For the length, use 52/4=13 pieces on the 4' side.
This gives a total of 4*13=52 sheets.
The extra 0.49' x 29.52 can be covered using the extra from the last four sheets for the width.

Check:
Area to be covered: 29.52*52.49=1550 sq. ft.
Area of plywood supplied = 52*4'x8'= 1664 sq. ft, > 1550 sq.ft.

Answer:

11) 0.6

12) The maximum height of the ball was 2[ seconds] after it was thrown (I am assuming because the answers are cut off a bit.)

13) $2.50

14) (2,-15)

15) I don't know, since I can't see all the graphs and options. But I want to say the sideways parabola, or the only one shown in the image given

Using the formula v= l x w x h find the volume of a right rectangular prism when the length of the prism is 45cm the width is 12

jeka94

V = length times width times height
V = 45 * 12 * 10
V = 5400

Hope this helps

Which theorem is it?<br><br> Answer choice below in the picture:

Ymorist [56]

Answer:

None of the above

Step-by-step explanation:

The figure3 shows 1 side and 1 angle of one triangle congruent to 1 side and 1 angle of the other triangle. We are not shown anything else, so the answer is:

None of the above

and you can't prove the triangles congruent.

PLEASE HURRY Find the measure of each missing angle.

Luba_88 [7]

<h2>Given:</h2>

m∠HFG = 71°

m∠EFH

<h2>Solution:</h2>

we know that the sum of all the angles on one side of a straight line = 180°

so,

m∠EFH +m∠HFG = 180°
m∠EFH +71° = 180°
m∠EFH = 180°-71°
m∠EFH = 109°

hence , option <em><u>c </u></em>⇴<em><u>109°</u></em> is correct

What should we multiply to eliminate fractions in an equation?.

il63 [147K]

Fractions can be defined as the representation of a part of a whole. A fractions consists of the numerator and the denominator.

let f(x) = $\frac{p}{q}$

then 'p' represents the numerator; while 'q' represents the denominator;

where p and q belong to integers for simple fractions, while when p and q belong to other sets they can from complex fractions.

To convert a fraction into an integer we need to multiply the fraction with the the denominator so that it cancels out leaving only the numerator behind.

For fractions present in equations to get rid of all the fractions we new to multiply the equation by the LCM of the denominator of all the fractions.

Where LCM is the least common multiple.

To give an example:

let y = $\frac{3}{4}$ X + $\frac{9}{5}$

Then the LCM for 4 and 5 will be 20;

as factor of 4 are 1,2 and that of 5 are 1,5

then to eliminate the fractions from the equation

Multiplying both sides by 20

y x 20= $\frac{3}{4}$ X x 20 + $\frac{9}{5}$ x 20

20y= 3 x 5X + 9 x 4

20y = 15X + 36
