Answer:
<h2>18mins</h2>
Step-by-step explanation:
This problem is on combined work rate
given that
Marta can vacuum the house in 30 min
then her rate= 1/30
Also, her daughter will take 45 min to vacuum the house
her daughter's rate will be = 1/45
then the combined work rate is
1/30+1/45=1/T
30+45/30*45=1/T
75/1350= 1/T
1/18=1/T

Answer:
For <em>2</em>, 30 cubic m., For <em>3</em>, 90 cubic cm., For <em>4</em>, 1000 cubic yards, for <em>5</em>, 27 cubic mm., For <em>6</em>, 120 cubic in.
Step-by-step explanation:
You can simply multiply all 3 sides to get the cubic volume B x <em>h </em>is the same as<em> l</em> x <em>w </em>x <em>h</em>
<em />
<em>ex. </em>Number 2, length 3, width 2, height 5
Base is<em> 2x3=6 </em>times <em>5 = 30 </em>or<em> 2 x 3 x 5=30</em>
