1) Um barbante tem 10,85 metros de comprimento. Se você dividir em 5 pedaços de mesmo comprimento, quantos centímetros terá cada pedaço? * 1 ponto (a) 2,17 cm (b) 217 cm (c) 21,7 cm (d) 0,217 cm
Answer:
(b) 217 cm
Step-by-step explanation:
The computation of the number of centimeters will each have is shown below:
= Length of the string ÷ number of pieces
= 10.85 meters ÷ 5
= 2.17 meters
= 217 centimeters
hence, the correct option is b.

Answer:
x = - 6
Step-by-step explanation:
Equation
1/3 * (-9x +12) = 22 Multiply both sides by 3
Solution
3 * 1/3(-9x + 12) = 22*3
- 9x + 12 = 66 Subtract 12 from both sides.
-9x = 66 - 12 Combine
-9x = 54 Divide by -9
x = 54/-9
x = - 6

Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa .
-Abby walks at a speed of 8 feet per second.
-Melissa walks at a speed of 9 feet per second.
Abby had been walking for BLANK seconds when both students had walked exactly the same distance. (round to the nearest whole)
please help me
Answer:
270 seconds
Step-by-step explanation:
Melissa's time = x seconds
Abby's time = (x + 30) seconds
Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.
But, speed = [tex]\frac{distance}{time taken}[/tex]
For Abby,
8 = [tex]\frac{distance}{(x + 30)}[/tex]
distance = 8(x + 30) ................. 1
for Melissa,
9 = [tex]\frac{distance}{x}[/tex]
distance = 9x ............. 2
From equations 1 and 2, for the same distance;
8(x + 30) = 9x
8x + 240 = 9x
x = 240 seconds
Abby's time = (x + 30)
= (240 + 30)
= 270 seconds
So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.
The time taken is 270 seconds.
Given that,
Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa . Abby walks at a speed of 8 feet per second. Melissa walks at a speed of 9 feet per second.Here we assume Melissa time be x and Abby time be x + 30Based on the above information, the calculation is as follows:
8(x + 30) = 9x
8x + 240 = 9x
x = 240
So Abby time should be
= 240 + 30
= 270
