Answer:

t ≥ 72

Step-by-step explanation:

The pool has to be at least 72° or MORE to open, so we are going to have a greater sign with an equal sign under indicating that the temperature has to  at least be 72° or be greater than 72°. (≥)

qwelly [4]
Okay, this is a proportion question. they make 45 flowers every 1 hour and 25 minutes, or 45/85(85 is equivalent to 1 hour and 25 minutes). and they made 100 flowers at the same rate as the first day. so you need to know how long it took them to make 100 flowers, if they make 45 every 85 minutes. so 45 (flowers) to 85 (minutes) = 100 (flowers) to x (minutes). or 45/85=100/x. so when you work that out, I came to 189 minutes, which is 3 hours and 9 minutes, so they stopped at 4:24. But you could round and get 4:25. Hope I didn't confuse you!

Jack broke apart 5x216 as (5x200)+(5x16) to multiply mentally. What strategy did Jack use?
Sveta_85 [38]

For this case we have the following multiplication:

5 * 216

We can rewrite this multiplication in the following way:

5 * (200 + 16)

From here, we apply the distributive property.

We have then:

(5 * 200) + (5 * 16)

Therefore, Jack's strategy is:

Write the number in an expanded form and then apply the distributive property.

Answer:

Jack's strategy is:

Write the number in an expanded form and then apply the distributive property.

The inverse, f'(x), of f(x) =
astraxan [27]

Step-by-step explanation:

Given

f(x) =  \frac{x + 5}{x}

So

f(2) = \frac{2 + 5}{2}  \\  =  \frac{7}{2}

Now

{f}^{ - 1} (x) =  \frac{5}{x - 1}

So

{f}^{ - 1} (2) =  \frac{5}{2 - 1} \\  =  \frac{5}{ 1}   \\  = 5

Hope it will help :)❤
