Ok, so you have the range correct. It is 120<___<150 (It should be less than or equal to, but there's no symbol for that, to my knowledge.) But the term in the middle shouldn't be .25x The reason is because that actually quadruples the price in the end, as you seem to have found out. Rather, instead of multiplying x by .25, multiply the numbers in the range by .75. Here's why: When you reduce something in price by 25%, you are paying for 75% of the original price. Not 25%. That would be a 75% discount. So, in all actuality,your answer would be $90

2. A square-based tent has the cross-sectional

ollegr [7]

(a) Length of the height is 2.732 m

(b) Length of the base is 5.466 m

<u>Explanation:</u>

An image is attached for reference.

(a)

In ΔAOB,

$sin 30^o = \frac{AO}{AB} \\\\0.5 = \frac{AO}{2} \\\\AO = 1 m$

In ΔBGD,

$sin 60^o = \frac{BG}{BD} \\\\0.866 = \frac{BG}{2} \\\\BG = 1.732 m$

According to the figure, BG = OE = 1.732 m

Height of the tent, AE = AO + OE

= 1 m + 1.732 m

= 2.732 m

(b)

DF = ?

In ΔAOB,

$tan 30^o = \frac{AO}{OB} \\\\0.577 = \frac{1}{OB} \\\\OB = 1.733 m\\\\\\$

According to the figure, OB = GE = 1.733 m

In ΔBGD,

$tan 60^o = \frac{BG}{DG} \\\\1.732 = \frac{1.732}{DG}\\ \\DG = 1m$

According to the figure, DE = DG + GE

DE = 1 m + 1.733 m

DE = 2.733 m

Length of the base, DF = 2 X DE

DF = 2 X 2.733 m

DF = 5.466 m

Of the 465 species of shark that

asambeis [7]

Answer: 16%

Step-by-step explanation:

The total number of species of shark evaluated = 465

Number of sharks currently endangered or threatened = 74

Percent of sharks endangered = (Number of sharks / Total number of sharks evaluated) x 100%

= (74/465) x 100%

= 0.1591 x 100%

= 15.91%

Round 15.91% to the nearest whole percent = 16%

Thus, 16% of the total sharks evaluated are currently endangered or threatened.
