part a
how many sets of clubs did jenny clean after 2 hours?
a 1 set c 3 sets
b 2 sets d 4 sets

part b
what does the point (6, 3) represent on the graph?
a jenny cleaned 6 sets of clubs, and each set took 3 hours.
b jenny cleaned 3 sets of clubs, and each set took 6 hours.
c jenny cleaned 3 sets of clubs in 6 hours.
d jenny cleaned 6 sets of clubs in 3 hours.

1. match the expression to the product.

1. a number in expanded form is shown. what is the number in standard form?

(3 × 100) + (6 × 10) + (4 × 1) + (8 × \\(\frac{1}{100}\\))
a 36.48 c 364.08
b 364.8 d 306.408

1. which numerical expression is the translation of the following written mathematical description?

double 10, then add 18.
a (10 × 2) + 18
b (10 ÷ 2) + 18
c (18 + 10) × 2
d (18 − 10) × 2

1. shane built a new table. the tabletop is a rectangular piece of wood that is 0.852 meters wide and 3.31 meters long.

part a complete the statement.
when the dimensions are rounded to the nearest whole number of meters, the length rounds to a 0 meter and the width rounds to a 3 meters.

part b complete the statement.
when the dimensions are rounded to the nearest tenth of a meter, the length rounds to a 0.8 meter and the width rounds to a 3.3 meters.

Explanation:

Step1: Solve Part A (Graph Q)

Locate x=2 on the graph, find y=1.

Step2: Solve Part B (Graph Q)

Point (x,y) = (time, sets), so (6,3) = 6 hours, 3 sets.

Step3: Solve Q8: Calculate each expression

$62.7 \times 0.1 = 6.27$ (matches B)
$62.7 \times 0.01 = 0.627$ (matches A)
$62.7 \div 0.1 = 627$ (matches C)
$62.7 \div 0.01 = 6270$ (matches D)

Step4: Solve Q9: Expand the expression

$(3 \times 100) + (6 \times 10) + (4 \times 1) + (8 \times \frac{1}{100}) = 300 + 60 + 4 + 0.08 = 364.08$

Step5: Solve Q10: Translate the description

Double 10 = $10 \times 2$, add 18: $(10 \times 2) + 18$

Step6: Solve Q11 Part A: Round to whole numbers

Length 3.31 rounds to 3; Width 0.852 rounds to 1.

Step7: Solve Q11 Part B: Round to tenths

Length 3.31 rounds to 3.3; Width 0.852 rounds to 0.9.

Answer:

Part A (Graph Question)

A. 1 set

Part B (Graph Question)

C. Jenny cleaned 3 sets of clubs in 6 hours.

Question 8

$62.7 \times 0.1$: B. 6.27
$62.7 \times 0.01$: A. 0.627
$62.7 \div 0.1$: C. 627
$62.7 \div 0.01$: D. 6,270

Question 9

C. 364.08

Question 10

A. $(10 \times 2) + 18$

Question 11 Part A

length rounds to B. 1 meter and the width rounds to A. 3 meters.

Question 11 Part B

length rounds to A. 3.3 meters and the width rounds to B. 0.9 meter.
