NeX [460]

Answer:

Please find attached the required graph of the inequality representing the temperatures yeast will NOT thrive

Step-by-step explanation:

The given parameters are;

The temperature range, y, in which yeast thrives is 90°F ≤ y ≤ 95°F

Therefore, the temperature range, y', in which yeast will not thrive is 90°F > y  and y > 95°F

The graph of the inequality that represents the temperature is therefore given as shown in the attached drawing.

navik [9.2K]

Answer

Find out the how long will it take the submarine to descend to the ocean floor

To proof

Formula

r = \frac{d}{t}

where  d  =  distance traveled (or descended),

r  = rate of travel , t  = time

As given

A submarine descends at a rate of 2.6 kilometers per hour. If the ocean floor is 6.24 kilometers below sea level .

put all the values in the above formula

2.6 = \frac{6.24}{t}

t = \frac{6.24}{2.6}

t = 2.4 hour

it take 2.4 hours the submarine to descend to the ocean floor .

Hence proved

Can someone help me find the answer?
raketka [301]

Answer:

AC=9 cm

ABC is not a right angled triangle

Step-by-step explanation:

AB=8cm

BC=5cm

22=AB+BC+AC

AC=22-8-5

AC=9

since AC is the longest,

using Pythagoras theorem

AC^2=BC^2+AB^2

9^2=8^2+5^2

81=64+25

81=89

therefore, it is not a right angled triangle
