Answer:
Below in bold.
Step-by-step explanation:
The total sum of the numbers in A is 124 and the sum of the numbers in B = 56
Let x be the number passed from A to B, then from the given information:
124 - x = 56 + x + 20
124 - 56 - 20 = 2x
48 = 2x
x = 24.
a) So the number passed is 24.
b) Sum of numbers in B = 56 + 24 = 80.
c) Let pencil cost x then pen will cost 1.1 - x.
Now the pen costs 1 pound more than the pencil
so 1.1 - x - x = 1
-2x = -0.1
x = 0.05.
So the pen costs 1.1 - 0.05 = £1.05.

The velocity function, in feet per second, is given for a particle moving along a straight line. () = 2 − − 42, 1 ≤ ≤ 12
Answers
Question:
The velocity function, in feet per second, is given for a particle moving along a straight line. [tex]v(t) = t^2 - t - 42[/tex] [tex]1 \le t \le 12[/tex]
Find the displacement
Answer:
The displacement is 42.17ft
Step-by-step explanation:
Given
[tex]v(t) = t^2 - t - 42[/tex] [tex]1 \le t \le 12[/tex]
The displacement x, is calculated using:
[tex]x = \int\limits^a_b {v(t)} \, dt[/tex]
[tex]x = \int\limits^{12}_{1} {t^2 - t - 42} \, dt[/tex]
Integrate
[tex]x = \frac{1}{3}t^3 - \frac{1}{2}t^2 - 42t|\limits^{12}_{1}[/tex]
Substitute 12 and 1 for t respectively
[tex]x = (\frac{1}{3}*12^3 - \frac{1}{2}*12^2 - 42*12) - (\frac{1}{3}*1^3 - \frac{1}{2}*1^2 - 42*1)[/tex]
[tex]x = (576 - 72 - 504) - (\frac{1}{3} - \frac{1}{2} - 42)[/tex]
[tex]x = (0) - (-42.17)[/tex]
[tex]x = 42.17[/tex]

help me Find the Area of the Trapezoid
Answers
Answer:
294
Step-by-step explanation:
14 x 9 = 126
so the area of your rectangle is 126.
15 - 9 = 6
so 6 is the width, 14 is the height.
14 x 6 = 84
now you have to multiply is by 2, because there is still another Triangle on the other side.
84 x 2 = 168
Now you take 168 and 126 and add your areas, and you have found the complete area!
168 + 126 = 294
I hope this helps! :)

Answer:
6(7x+10)
Step-by-step explanation:
Hello There!
We can find an equivalent expression by factoring
First we need to find the greatest common factor (GCF)
GFC - largest number that both numbers can be divided by
Lets write down all of the multiples of each number
42 - 42 and 1, 21 and 2, 13 and 3, 6 and 7,
60 - 60 and 1, 30 and 2, 20 and 3, 4 and 15, 6 and 10
Then we find the greatest common factor which would be 6
42x/6=7x
60/6=10
so we can conclude that an equivalent expression would be
6(7x+10)

Answer:
25
Step-by-step explanation:
a^2 + b^2 = c^2
Here, c is the hypotenuse. We'll plug the given numbers into the equation, so we get:
15^2 + 20^2 = c^2
225 + 400 = c^2
625 = c^2
To undo a squared number, you find the square root of it:
[tex]\sqrt625[/tex] = 25
Your answer is 25! If you need more help, just ask :D

eight times a number plus five times another number is -13. the sum of the two is 1. What are the numbers?
Answers
Answer:
-6 and 7
Step-by-step explanation:
x is one number and y is the other
(1)----------------- 8x+5y=-13
(2)------------------ x+y= 1
first, let multiply both sides of (x+y=-1) by 8
(3)----------------- 8x+8y=8
lets subtract (1) from (3)
(8x+8y)-(8x+5y)=8-(-13)=3y
8-(-13)=3y -> 21=3y
y=7
lets plug in 7 into (2) for x
x+7=1
x=-6
the numbers are -6 and 7

hey i know this may be a lame question but can anyone help me how can i multiply 16 with 3,142 (with steps) ?? :/
Answers
Answer:
50272
Step-by-step explanation:
Okay how I solve these equations is I take the problem apart like this:
3142 = 3000 + 100 + 40 + 2
Now we multiply each number by 16:
3000 * 16 = 48000
100 * 16 = 1600
40 * 16 = 640
2 * 16 = 32
Then we add all the totals together:
48000 + 1600 + 640 + 32 = 50272
Hope this Helps ;)
