The Atlantic Salmon swim upstream at a steady rate of 2 miles every 3 minutes. Fill in the table to describe the relationship. R
Likurg_2 [28]

The distance traveled by the Salmon is proportional to the duration spent

swimming.

A table of the distance traveled by the Atlantic Salmon is presented as follows;

\begin{tabular}{|c|c|c}\underline{Time in minutes}&\underline{Miles Traveled  at 2/3 miles per minute } \\1&2/3  \\2&4/3\\3&2\\4&8/3\\5&10/3\\6&4\end{array}

Reasons:

The given parameter are;

The steady rate at which Atlantic Salmon swims = 2 miles in 3 minutes

Distance the Salmon swims, d ∝ Time taken, t

Therefore;

d = s·t

Where;

s = The constant of proportionality = The speed

Which gives;

\displaystyle s = \mathbf{\frac{Distance, \, d}{Time, \, t}}

The speed with which the Atlantic Salmon swims per minute is therefore;

\displaystyle The \ speed = \mathbf{\frac{2 \ miles}{3 \ minutes}} = \frac{2}{3} \ miles /minute

The distance travelled, <em>d</em>, is given as follows;

\displaystyle d = \mathbf{\frac{2}{3} \times t}

A table showing the distance travelled by the fish with time is presented as follows;

\begin{tabular}{|c|c|c|}\underline{Time, t, in minutes}&\underline{t \times d}&\underline{Miles Traveled, d,  at 2/3 miles per minute } \\1&1 \times 2/3 = 2/3&2/3  \\2&2 \times 2/3 = 4/3&4/3\\3&3 \times 2/3 = 2&2\\4&4 \times 2/3 = 8/3&8/3\\5&5 \times 2/3 = 10/3&10/3\\6&6 \times 2/3 = 4&4\end{array}

Pyramide-shaped gift boxes have square bases that measure 5 inches on each side.The slant height is 6.5 inches.How much cardboar
andrew-mc [135]
1. square base area= 25 inches

2. using the slanted 6.5
=1/2base , therefore 5/2=2.5 inches

3. then use pythagoras.... c=6.5, a=2.5
c^2=a^2 + b^2
(do this urself)

4. when u find what b is... that's the height of one of the triangle
base= 2.5 (look at step 2 if u don't understand this bit)
height=b (refer to step 3)

5. then work out the area of 1 triangle using that...
6. then have (the answer u work out in step 5 ) multiply 4
this will give u the area for the all of the 4 triangles...

7. Then add together the square based area in step 1..(25)
to the 4 triangular, area faces (i.e from step 6) - the total will be ur answer for the amount of cardboard!!

p.s don't forget the units!!!
