which expression simplifies to 41? choose all that apply! question 14 options: 10 2³ ∙ 4 - 1 10 2³ ∙ (4 - 1) (10 2³) ∙ 4 - 1 10
nordsb [41]

The expressions that simplifies to 41 are:

a) 10 + 2³ * 4 - 1

d) 10 + (2³ * 4) - 1

Information about the problem:

a) 10 + 2³ * 4 - 1

b) 10 + 2³ * (4 - 1)

c) (10 + 2³) * 4 - 1

d) 10 + (2³ * 4) - 1

We solve the equations respecting the level of hierarchy:

  • First the operations in parentheses, then brackets and finally braces.
  • Of the arithmetic operations, first the multiplication and divisions and then the additions and subtractions.

a) 10 + 2³ * 4 - 1

10 + 8*4 - 1

10 + 32 - 1

42 - 1

41 (it applies)

b) 10 + 2³ * (4 - 1)

10 + 8 * (3)

10 + 24

34 (it doesn't applies)

c) (10 + 2³) * 4 - 1

(10 + 8) * 4 - 1

18*4 - 1

72 - 1

71 (it doesn't applies)

d) 10 + (2³ * 4) - 1

10 + (8*4) - 1

10 + 32 -1

42 - 1

41 (it applies)

Pedro spent 2 1/5 hours on his math homework and half as long on his science homework one weekend. If his English and social stu
Flura [38]

2 1/5 hours on homework for math = 2.2

Science homework took 1.1 hours to complete.

2.2+1.1= 3.3

7/8 of an hour is 50 minutes because we know that an hour is 60 minutes and every 10 minutes is a number for the numerator, if that makes sense.

3.3 of an hour plus 50 minutes, would equal 3.8 since the 3 after the point would be minutes. To convert into hours, since an hour is 60 minutes, we have 4 hours and 20 minutes he spent on homework over the weekend. That would be your answer! Hope this helped.

Marat540 [252]
Let c be the ounces of clay that Elisa used. For small vases, the value of c should be less than or equal to 4.5 which can mathematically be expressed as c ≤ 4.5. For large vases, the value of c should be greater than or equal to 12, c ≥ 12. Thus, the answer to this item is letter D.
