marin [14]

Answer:

544

Step-by-step explanation:

The ratios of cartons are ...

B : P = 2 : 1

S : L = 2 : 1

L : B = 2 : 1

Combining these into a single set of ratios, we have ...

S : L : B : P = 8 : 4 : 2 : 1

Then the proportion of the order that is strawberry is ...

8/(8+4+2+1) = 8/15

and the number of strawberry cartons is ...

(8/15)·1020 = 544

The store ordered 544 cartons of strawberry yogurt.

makvit [3.9K]

Answer:

$|T- 98.6| \geq 3$

And in order to solve this we have two possibilities:

Solution 1

$T -98.6 \leq -3$

And solving for T we got:

$T \leq 98.6- 3$

$T\leq 95.6$

Solution 2

And the other options would be:

$T -98.6 \geq 3$

$T \geq 101.6$

Step-by-step explanation:

For this case we can define the variable os interest T as the real temperature and we know that if we are 3 F more than the value of 98.6 we will be unhealthy so we can set up the following equation:

$|T- 98.6| \geq 3$

And in order to solve this we have two possibilities:

Solution 1

$T -98.6 \leq -3$

And solving for T we got:

$T \leq 98.6- 3$

$T\leq 95.6$

Solution 2

And the other options would be:

$T -98.6 \geq 3$

$T \geq 101.6$
