Answer:
54 teachers
Step-by-step explanation:
Step one:
given data
The ratio of teachers to students on a field trip to New York City is 2 to 9.
That is the ratio is 2:9
We are told that there are 243 students
Required
We want to find the number of teachers
Step two:
Applying the part to part method we have
let the number of teachers be x
2/9= x/243
cross multiply we have
9x= 243*2
9x= 486
divide both sides by 9
x= 54
Hence there are 54 teachers
Answer:
w = 5 , w = -5

sqrt(w^2) = ± sqrt(25)
w = ±5
240 each 10 percent is 30 calories multiply them by ten gets you 300
Answer:
look at the picture .................
<em>Length = </em><em>80</em>
<em>Breadth = </em><em>30</em><em> </em>
<em>Height = </em><em>30</em>
<em>Total surface area of a cuboid is= </em>
<em><u>2 ( lb + bh + hl )</u></em>
<em>Putting the values in the formula,</em>
<em>We get,</em>
<em>= 2</em><em> [</em><em> (80 x 30) + (30 x 30) + (30 x 80)</em><em>]</em>
<em>= 2 (2400 + 900 + 2400)</em>
<em>= </em><em><u>8100 cm²</u></em>
