10000ft - 9450ft = 550ft

9450ft - 8900ft = 550ft

The airplane is descending 550ft every minute

550 * 12 = 6600

10000ft - 6600ft = 3400ft

After 12 mins, the airplane will be 3400ft

Please Help!! If mc014-1.jpg, what is the value of c?<br><br> **see attachment
Y_Kistochka [10]
This is the concept of algebra, we are required to solve the given expression;
32^(2c)=8^(c+7)
this can be written as:
2^[5(2c)]=2^[3(c+7)
applying the natural logs we shall get
[5(2c)]ln2=[3(c+7)]ln2
The ln 2 will cancel on from both sides and we shall have:
5(2c)=3(c+7)
10c=3c+21
To make c the subject we begin by subtracting 3c from both sides
10c-3c=3c+21-3c
7c=21
dividing both sides by 7 we get:
(7c)/7=21/7
c=3
The answer is c=3

kevin wants to make a mixture that is 50% lemon juice and 50% lime juice how much 100% lesson juice should he add to a juice mix
fiasKO [112]

Answer:

Kevin must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime.

Step-by-step explanation:

Given : Kevin wants to make a mixture that is 50% lemon juice and 50% lime juice. 100% lesson juice should he add to a juice mixture that is 40% lemon juice and 60% lime juice to make 6 gallons of the 50% lemon 50% lime juice mixture.

To find : How much 100% lesson juice should he add to a juice mixture.

Solution :

According to question, we wants to make mixture where lemon = lime

We have to make 6 gallons, where

40% lemon juice require to make 6 gallon

i.e,  40\% \text{ of } 6= 0.4 \times 60=2.4

and 60% lime juice require to make 6 gallon

i.e,  60\% \text{ of } 6= 0.6 \times 60=3.6

Now, to make them equal subtract both of them

\Rightarrow 3.6-2.4=1.2

Therefore, he must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime.
