Answer:

l = 6 cm

w = 5 cm

Step-by-step explanation:

l(2l - 7) = 30

2l^2 - 7l - 30

(2l + 5)(l - 6)

l = 6

2(6) - 7 = 5

Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found. A squirrel hid 40 nuts all together.

koban [17]

Answer:

15 nuts do not get found.

Step-by-step explanation:

Given that Of a squirrel's hidden nuts, for every 5 that get found, there are 3 that do not get found.

Total number of nuts squirrel had hidden = 40

Proportion of nuts not found to total = 3/(3+5) = 3/8

Hence out of 40, nuts not found =3/8(40) = 15 nuts.

15 nuts would not be found and 25 nuts would be found if squirrel had hidden in total 40 nuts.

This is because the proportion of found:unfound = 5:3

Hence 25:!5 =5:3 satisfies this

15 nuts are not found.

gavmur [86]

Answer:

The percentage error in the prediction = 10.20%

Step-by-step explanation:

A sports broadcaster predicts a basketball team will score 88 point me in the next game.

If the team has actually scored 98 points we have to find the percentage error in the broadcaster's prediction.

The deviation of the prediction from the actual value = 98 - 88 = 10.

The formula for finding error percentage = $\frac{deviation from actual value}{prediction}$

= $\frac{10}{98} \times 100$

= 10.20 %

The percentage error = 10.20%
