Out of 4,000 colleges surveyed, 60% reported that SAT scores were not used as a high consideration in viewing their applications
Oduvanchick [21]

Answer:

Hi.  

The first thing you want to know is how many schools 60% is.

To find 60%: 4,000 x 0.6 (b/c 0.6 = 60%)  

so, 60% of 4,000 = 2,400

To find the number of schools that consider SAT scores:  

Subtract 2,400 from 4,000 which, equals 1,600

              or

Find the remaining percentage; 40%:

4,000 x 0.4 = 1,600

Answer: 1,600 colleges

I hope this helps a little bit.

25 pts and a mark for real answers. Help!! A store is having a sale on chocolate chips and walnuts. For 5 pounds of chocolate ch
kozerog [31]

Answer:

Each pound of chocolate chips costs $ 1.5 and each pound of walnuts cost $ 3.75 .  

Step-by-step explanation:

Let, each pound of  chocolate chips costs  $ x and each pound of walnuts costs $ y.

Then,  according to the question,

5x + 6y = 30 --------------(1)   and,

3x + 2y = 12 ----------------(2)

Multiplying (2) by 3 we get,

9x + 6y = 36 ---------------------(3)

Deducting  (1) from  (3) we get,

4x = 6

⇒ x = 1.5 ----------------------(4)

From (4), putting the value of x in (2) , we get,

2y = 7.5

⇒ y = 3.75 ---------------------------(5)

Please help me out! express the inequality using interval notation
svetoff [14.1K]

Answer:

(7, ∞)

Step-by-step explanation:
