Laura plans to paint the 8 foot high rectangular walls of her room, and before she buys paint she needs to know the area of the
hram777 [196]

Answer:

B: 340

Step-by-step explanation:

We are told that her walls are 8 ft high.

Now, Two walls are 10 feet wide. Thus, area of the first two walls will be;

A1 = 2 × (10 × 8) = 160 sq.ft

Also, the other 2 walls are 15 feet wide.

Thus, Area of other two walls will be;

A2 = 2 × (15 × 8) = 240 sq.ft

We are told that the combined area of the 1 window and the 1 door in her room in 60 square feet.

This means that we will subtract 60 Sq.ft from the sum of the area of the 2 walls earlier calculated to get the total area to be painted.

Thus;

Area to be painted = 160 + 240 - 60 = 340 Sq.ft

Mekhanik [1.2K]
I'll just make a manual computation on how 1 member recruits his members until week 5. Then multiply the sum by 2.
                                old      new
1:   1
2:   1 x 3 = 3 ⇒        1         3       *only new members recruit 3 more
3:   3 x 3 = 9 ⇒        4         9 
4:   9 x 3 = 27⇒     13       27
5: 27 x 3 = 81 ⇒    40       81

40 + 81 = 121. Total number of members under 1 founding member.

121 x 2 founding members = 242 total number of members within 5 weeks.

To find the quotient of 4 divided by 1/5, multiply 4 by <br> 1/5<br> 1/4<br> 4<br> Or <br> 5
alina1380 [7]

Answer:

5

Step-by-step explanation:

When dividing numbers by fractions, we can simply multiply the  umber by the reciprocal of the decimal. So,

4 ÷ 1/5 = 4 × (reciprocal of 1/5)

A reciprocal of a number is the same number written under 1. aka, 1 divided by that number, which simply is flipping the numerator and denominator of a number.

So the reciprocal of 1/5 is 5/1 = 5.

So 4 ÷ 1/5 = 4 × 5.

So your answer is 5.

hope it was useful!!! ;)
