If four ounces of orange juice contain 50 calories, how many ounces of orange juice will have 175 calories?

175 calories. is obtained by 14 ounces of orange juice.

Step-by-step explanation:

Given :    four ounces of orange juice contain 50 calories

We have to find how many ounces of orange juice will have 175 calories.

UNITARY METHOD is a method in which we first find the value of a single unit and then multiply it with desired quantity.

Consider the given statement

four ounces of orange juice contain 50 calories

Apply unitary method ,

50 calories is obtained by 4 ounces of orange juice

1 calorie is obtained by ounces of orange juice.

Thus, 175 calories. is obtained by ounces of orange juice.

Simplify  , we have,

175 calories. is obtained by 14 ounces of orange juice.

Thus,  175 calories. is obtained by 14 ounces of orange juice.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

5+2x=a
