Joan needs to estimate the size of her bedroom so that she can buy enough paint to cover the walls. Two of the walls measure 2.8

labwork [276]

The total area of the room is 37.6376 and the no. of cans required to paint the wall is 3 cans.

The measurement of two of the walls is 2.86 metres and 3.16 metre

Area of the two walls = 2(length x breadth)

Area = 2(2.86 x 3.16) = 18.0752 m²

The measurement of the other two walls is 2.86 metres and 3.42 metres

Area of the two walls = 2(length × breadth)

Area = 2(2.86 × 3.42) = 19.5624 m²

Total area = 18.0752 + 19.5624 = 37.6376 m²

If one can of paint can cover 15 m², the no. of cans required to paint the bedroom will be

No. of cans = Total area/Area covered by one can of paint

No. of cans = 37.6376/15 = 2.5091 = 3 cans (approx.)

A trapezoid has a height of 8 cm and bases with lengths of 14 cm and 8 cm. Tina says the area of the trapezoid is 176 cm2.

Sonbull [250]

Answer:

Step-by-step explanation:

Let's do this properly:

Area of trapezoid = average length times height.

Here,

Area = (1/2)(8 cm + 14 cm)(8 cm), or

= (11 cm)(8 cm) = 88 cm^2

It appears that Tina forgot to divide the sum of 14 cm and 8 cm by 2. Thus, her answer is twice as large as it should be.

The simplest form of the expression 4m-17/m^2-16 + 3m-11/m^2-16 has ____in the numerator and___ in the denominator.

lara31 [8.8K]

For this case we have the following expression:
$\frac{4m-17}{m^2-16} + \frac{3m-11}{m^2-16}$
Since the denominator is equal, then we can add the numerator.
We have then:
$\frac{(4m-17) + (3m-11)}{m^2-16}$
Adding similar terms we have:
$\frac{(4m+3m) + (-17-11)}{m^2-16}$
Rewriting we have:
$\frac{7m - 28}{m^2-16}$
Doing common factor in the numerator we have:
$\frac{7(m - 4)}{m^2-16}$
Factoring the denominator we have:
$\frac{7(m - 4)}{(m-4)(m+4)}$
Canceling similar terms we have:
$\frac{7}{m+4}$
Answer:
The simplest form of the expression has 7 in the numerator and m+4 in the denominator.
