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.

A train leaves at 14.54 and arrives at its destination at 15.47. If the train travelled 66 km, what was it's average speed in km/h? Give your answer rounded to 1 dp. step by step explanation
Answer: average speed of the train = 4,483.0 km/h
Step-by-step explanation:
Speed = Distance / Time
Distance = 66 km
Time = 15.47 cancelling 15, we have 60 sec added to 47 sec
- 14.54
= 14. 107 60 + 47
- 14. 54
53secs
53secs to hours becomes =
60 secs = 1 min
60 min= i hour
therefore 53seconds =53/3600=0.0147222hours
Speed= 66/ 0.0147222= 4,483.025
Rounding to 1 dp becomes= 4,483.0 km/h

Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a
Answer:
140°
Step-by-step explanation:
Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a
The value of the smallest angle is given as:
= 3/8 of the 160 angle
=3/8 × 160°
= 60°
The sum of the total angle = 360°
Hence:
360° = 60° + 160° + a
a = 360° - (60° + 160°)
a = 360° - 220°
a = 140°
Therefore, a = 140°

Answer:
Step-by-step explanation:
i think you do 34x + 12
bc it is a same side interior angle and i think that equals 180 and then you

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

Answer:
8) ΔCAB ~ ΔFDE; SSS
9) ΔMNQ ~ ΔPNO; SAS
10) ΔDBE ~ ΔABC; SAS
Step-by-step explanation:
8) The side ratios, shortest to longest, are ...
6 : 8 : 10 = 9 : 12 : 15 = 3 : 4 : 5
so are the same for both triangles. Triangles CAB and FDE are similar by SSS.

9) MN/NQ = PN/NO = 6/5 = 12/10. The vertical angles between these corresponding sides are congruent. Triangles MNQ and PNO are similar by SAS.

10) BD/BA = BE/BC = 21/28 = 24/32 = 3/4. The shared angle between the corresponding sides is congruent to itself. Triangles DBE and ABC are similar by SAS.

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
Solve the simultaneous equations by substitution
3y - 2x = -7
5x + 3y = 28
Answer:
(5, 1 )
Step-by-step explanation:
Given the 2 equations
3y - 2x = - 7 → (1)
5x + 3y = 28 → (2)
Rearrange (1) expressing 3y in terms of x by adding 2x to both sides
3y = - 7 + 2x
Substitute 3y = - 7 + 2x into (2)
5x - 7 + 2x = 28
7x - 7 = 28 ( add 7 to both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5(5) + 3y = 28
25 + 3y = 28 ( subtract 25 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (5, 1 )
Answer:
-(3y-2x= -7)
3y+5x= 28
-3y+2x= 7
3y+5x= 28
7x=35
7x/7= 35/7
x=5
5(5)+3y= 28
25+3y=28
3y= 28-25
3y=3
3y/3=3/3
y= 1
3y-2x= -7
3(1) -2x= -7
3-2x= -7
-2x= -7-3
-2x= -10
-2x/-2=-10/-2
x= 5

5x+3y=28
5(5)+3(1)=28

y = 2.3 - 11
-2 + y = -4
Solution:
Answer:
Number 1: -8.7. Number 2: -2
Step-by-step explanation:
To find the first one, subtract 11 from 2.3.
2.3-11= -8.7 , so that's the answer for the first one.
To find the answer to the second one, just do -4+-2=-2, so that's the answer for the second one.
