the size of a rectangular photo frame is 12 11/16cm by 8 3/4cm. Which of the following gives the product of these dimensions rounded to the nearest whole number of centimeters
answers
A) 12 cm x 8 cm
B) 12 cm x 9 cm
C) 13 cm x 8 cm
D) 13 cm x 9 cm

Answers

Answer:

D

Step-by-step explanation:

the answer can't be A or C because we know that 8 3/4 rounds to 9

so we have to figure out if 12 11/16 is closer to 12 or 13

anything above 8/16 should round up; therefore, 11/16 should round the 12 to be 13

Step-by-step explanation:

Given

[tex]Average = 22.4[/tex]

[tex]Insurance = \frac{3}{4}[/tex]

Required

How many do not have insurance (average)

First, calculatet he fraction of those without insurance (x).

[tex]x = 1 - Insurance[/tex]

Substitute value for Insurance

[tex]x = 1 - \frac{3}{4}[/tex]

[tex]x = \frac{1}{4}[/tex]

how long would the toy car be?...

Answers

Answer:

6.37 cm.

Step-by-step explanation:

Since Hot Wheels uses a scale ratio of 1:64 (1 cm to scale = 64 cm actual) for their toys, knowing that the actual length of a VW Beetle is 160.6 inches, to determine the length of the toy car is you must perform the following calculation:

1 inch = 2.54 cm

(160.6 x 2.54) / 64 = X

407.924 / 64 = X

6.373 = X

Therefore, the size of the toy car will be 6.37 cm long.

On her first day, Ripley proved that she was just as good as Ellie. The instructor even believed that she could perform better than Ellie.
