Answer:

Tommy earned $55

Step-by-step explanation:

Proportions

Tommy and Mark made $88 raking leaves for Mrs. Bopp. They were paid the same rate and Tommy raked for 5 hours while Mark raked for 3 hours.

The total time both raked is 5+3=8 hours. The rate Mrs. Bopp paid them was $88/8 = $11 per hour.

Tommy raked 5 hours, so he earned 5*$11 = $55

Tommy earned $55

AVprozaik [17]

Answer:

Class width=20

Lower class limit of first class=100

Upper class limit of first class=120

Step-by-step explanation:

The class width can be calculated by taking the difference of two consecutive upper class limits or lower class limits.

Now we take any two consecutive upper class limits or lower class limits from classes 100-120,120-140,140-160,160-180,180-200,200-220,220-240.

We take upper class limits of first and second class i.e. 100 and 120.

Class width=120-100=20

Class width=20

The approximate lower and upper class limits of the first class from classes 100-120,120-140,140-160,160-180,180-200,200-220,220-240 are 100 and 120.

Class limits for first class is 100-120.

Lower class limit of first class=100

Upper class limit of first class=120

Answer:

Step-by-step explanation:

A calculator is your friend for such problems.

___

Evaluating these by hand, the Order of Operations applies. First you do what's in parentheses, then you do multiplication, then addition/subtraction.

1. (3/4)·(12·4 -16) -20 = (3/4)(48 -16) -20 = (3/4)·32 -20 = 24 -20 = 4

2. (5/9)·(12·6 -42 +15) = (5/9)·(72 -42 +15) = (5/9)·(30 +15) = (5/9)·45 = 25

___

Of course, the Order of Operations applies within each level of parentheses.

Adding the opposite of a number is the same as subtraction. Likewise, subtracting the opposite of a number is the same as adding the number. The usual associative and commutative properties of addition and multiplication apply. Among other things, that means you can compute the product of an integer and a fraction in any convenient way:

(3/4)·32 = 3·(32/4) = 3·8 = 24

(5/9)·45 = 5·(45/9) = 5·5 = 25
