Given :
A freight elevator has a weight limit of 15,000 pounds.
Workers have loaded items weighing 2.6 tons onto the elevator.
To Find :
How many more pounds of freight can they load before reaching the weight limit.
Solution :
We know, 1 ton = 2000 pounds.
So, 2.6 ton = 2.6 × 2000 = 5200 pounds.
Now, number of pounds of freight can be loaded before reaching the weight limit is :
N = 15000 - 5200 pounds
N = 9800 pounds

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

From corresponding angles theorem, we can see the 2 angles are equal.
16x+13=18x-1
2x=14
x=7
Done!
Any questions just leave them in the comments and I will answer.
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
34x+12=180
-12 - 12
34x= 168

Solve by substitution.
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.
Considera a sequencia: 5,9,13,17,21...Indica a expressão geradora desta sequencia. 5n 4n+1 5n-1 3n+1
Responder:
Tn = 4n + 1
Explicación paso a paso:
Dada la secuencia aritmética
5,9,13,17,21 ...
Debemos encontrar el enésimo término de la secuencia
Tn = una + (n-1) d
a es el primer término = 5
n es el número de términos
d es la diferencia común
d = 9-5 = 13-9
d = 4
Sustituir en la ecuación
Tn = 5+ (n-1) (4)
Tn = 5 + 4n-4
Tn = 4n + 5-4
Tn = 4n + 1
Por tanto, el enésimo término de la secuencia se expresa como Tn = 4n + 1

What is the length of the missing leg?
Answer:
b = 24
explanation:
you use the Pythagorean theorem.
a^2 + b^2 =c^2
so we do 32^2 + x^2 = 40^2 then solve
32 squared is 1024 and 40 square is 1600 so you minus the 2 and get 576 then you square root 576 and you finally answer is 24

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.
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

2.) LaSalle Peru Township High School is selling tickets to a football fundraiser dinner. On the first day of
ticket sales LP sold 4 adult tickets and 2 child tickets for a total of $52. LP took in $132 on the second day by
selling 12 adult tickets and 4 child tickets. What is the price each of one adult ticket and one child ticket?
Answer:
a = 7 and c = 12
Step-by-step explanation:
Set up 2 equations and use substitution:
4a + 2c = 52
12a + 4c = 132
In the first equation, c = 26 - 2a
We can plug that into the second equation to solve for a.
12a + 4(26 - 2a) = 132
a = 7
Plug a back in to either original equation to solve for c:
4(7) + 2c = 52
c = 12

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:
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.

The points (0,3), (1,8), (2,17), and (3,30) are on the graph of a function. Which of the following equations represents that function?
a.2x^{2}-3x+3
b.2x^{2}+3x-3
c.2x^{2}-3x-3
d.2x^{2}+3x+3
Answer:
D. 2x^{2}+3x+3Step-by-step explanation:
Use the ordered pairs to determine the correct function
Point (0, 3)
x = 0 and y = 3- options A or D, the others result in y = -3Point (1, 8)
x = 1, y = 8 - option A.
2*1^2 - 3*1 + 3 = 2 - incorrectIt leaves us with option D
2*1^2 +3*1 + 3 = 8 - correctCheck other two pairs as well:
2*2^2 + 3*2 + 3 = 172*3^2 + 3*3 + 3 = 30This confirms option D is correct
