Answer:
[tex]s^2+11s+15[/tex]
Step-by-step explanation:
Let side length of pool=s
According to question
Length of rectangular deck , l=2s+5
Width of rectangular deck, b=3+s
We have to find the area of deck in terms of s.
We know that
Area of square=[tex](side)^2[/tex]
Area of rectangle=[tex]l\times b[/tex]
Using the formula
Area of pool=[tex]s^2[/tex]
Area of (rectangular deck+ pool)=[tex](2s+5)(3+s)[/tex]
Now,
Area of rectangular deck
=[tex](2s+5)(3+s)-s^2[/tex]
[tex]=6s+2s^2+15+5s-s^2[/tex]
=[tex]s^2+11s+15[/tex]
A 1kg book is lifted 2m. How much work was done?
Answer:
work= force ×distance
force= mass × acceleration due to gravity
mass= 1kg
acceleration=10
Force=1×10=10N
Work=10×2=20joules
The work done is 20 joule.
What is Work done?
It should be converted to energy in order to move an object. Energy can be transferred by the use of force. Work done refers to the amount of energy used by a force to move an object.
Given:
mass, m= 1 Kg
So, force = mg = 1 x 10 = 10 N
and, displacement = 2m
Now, work done= force x displacement
= 10 x 2
= 20 Joules.
Hence, the work done is 20 joule.

Simplify the expression shown
-3√6-3√20-√6
And also please show work and explain how you got the answer!!!
Answer:
-4√6-6√5
Step-by-step explanation:
-3√6-3√20-√6 = (-3√6-√6)-3√20 = -4√6-3√20
√20 = √4*√5 or 2√5
substitute that in and you get -4√6-3(2√5) which then becomes
-4√6-6√5

entre 4 grupos de un colegio recolectaron 200kg de papel para reciclarlo.el primer grupo recogio 60 1/4 kg el segundo 13 1/5 y el tercero 45,93 kg cuanto recogio el cuarto grupo?
Answer:
segun yo es asi no confies mucho en mi
Step-by-step explanation:
200 kg total de papel
primer grupo= 60kg
segundo= 13kg
tercero= 45.93
cuarto= x
si sumamos el total recolectado por los tres primero grupos
60+13+45.93
esto nos da
118.93
si en total se recgio 200kg de basura y tenemos que los tres primeros grupos recogieron 118.93, entonces solo queda restar el total menos lo recolectado
200-188.93= cuarto grupo
cuarto grupo=81.07kg
Roberto earns $6.50 per hour. He worked 32 hours at the regular rate, 8 hours at a time and a half, and 8 at double time. How much did he earn?
Answer $390
Step-by-step explanation:
Answer:
$390
Step-by-step explanation:
First Roberto works 32 hours at 6.50 per hour. At that time, he earn 32*6.5 = $208. Then he works 8 hours at a time and a half. This means that his pay rate is 50% more, or 6.5*1.5 = $9.75 per hour. Since he worked 8 hours at this pay rate, he earns 8*9.75 = $78. And then he works 8 hours double time. This means his pay rate was doubled during that duration. 6.5*2 = 13, 13*8 = $104.
Total: 208 + 78 + 104 = $390
Find the missing angle measurement in the triangle.
Answer:
the answer is C
Step-by-step explanation:
the right angle is = 90
the other angle= 55
so you add them together which makes 145
so subtract 180 which is = to a triangle subtract 180-145=35
Answer: C.)
Step-by-step explanation:
Triangle angles add up to 180 degrees.
The box is a right angle which equals 90 degrees.
55 degrees + 90 degrees = 145 degrees, but we need the sum to be 180, so we subtract 145 from 180 and you should get the answer of "35".
