1. D. 81 cm sq.
Shape: Square
Formula: P = 4s so 44 = 4s so s = 11 cm
Formula: A = s^2 so 11^2 = 121 cm sq.
2. £200
Shape: Square
Formula: P = 4s so P = 4(0.5) so P = 2 m
1 meter = 100 centimeters
So 2 m = 200 centimeters
3. 210 m
Shape: Triangle
Formula: P = a + b + c so P = 15 + 20 + 35 = 70 m
He travels around 3 times so 3x = 3(70) = 210 m
4. 150 m
Shape: Pentagon
# of Sides: 5
Formula: P = 5s so P = 5(30) so P = 150 m
5. 288 m
Shape: Rectangle
Formula: A = LW so A = 48 * 6 so A = 288 m
Answer:
(repeating, which is usually signified by a line over the 6, but I couldn't type that)
Step-by-step explanation:
________
15 | 4
__._____
15 | 4 0 since 15 is bigger than 4, add a 0 here.
make sure you also place a decimal point
above (above the place directly after 4) so your
answer isn't larger than it should be.
__.2____
15 | 4 0
3 0 15*2 = 30. that's as close to 40 as we're going to get.
__.2____
15 | 4 0
<u>-30 </u>
10 40 - 30 = 10.
__.2____
15 | 4 0
<u>-30 </u>
1 0 0 bring down an imaginary 0.
__.26___
15 | 4 0
<u>-30 </u>
1 0 0
<u> - 90 </u> 15*6 = 90. that's as close to 100 as we're going to get.
1 0
Notice that we keep getting 10 as a remainder again if we keep going. So 6 keeps repeating on top, which is why it's a repeating decimal. Once you realize it's the same number again and again the further you divide it, you can stop and write the line over the 6.
Answer: 0.1666
Step-by-step explanation: To find the probability of an event, you divide the number of favorable events by the number of total events. Since there are 6 total events, and rolling a 4 counts as 1 event, you would divide 1 by 6.
1/6 = 0.1666
Answer:
the mode is 7 because they have the most points
