Answer:
Potential Energy = 8550 Joules
Step-by-step explanation:
The potential energy of the body is the energy possessed by it due to its position therefore:
Potential energy = mgh
m = mass of the body measured in kg
g= acceleration due to gravity
h= height or distance measured in meters
But in the question asked we are not given mass but weight so
w= mg measured in newtons
We have
w= 190 N
h= 45m
PE= mgh
PE = w h= 190 * 45 = 8550 J
The unit of energy is Joule.

In this hanger, the weight of the triangle is x and the weight of the square is y.
Write an equation using x and y to represent the hanger.
9514 1404 393
Answer:
x +3y = 4x +y
Step-by-step explanation:
Apparently, the "hanger" is in balance between its left side, which weighs x+3y, and it right side, which weighs 4x+y. We can represent this balance by ...

There are 312 calories in six ounces of a certain ice cream. How many calories are there in three pounds?
Answer:
2496 calorise
Step-by-step explanation:
3 pounds = 3 x 16 = 48 ounces
312 cal = 6 ounces, so the unit rate is ( 312 ÷ 6 = 52) 52 cal per ounce
52 x 48 ounces = 2,496

You and your friends order Dominos pizza. Each pizza costs $5.25 and each drink costs $1.75. Write an equation to represent what the total cost would be.
Answer:
[tex]5.25x + 1.75y = b[/tex]
Step-by-step explanation:
⇒Lets solve!
⇒ First we must define our variables!
x = number of pizzas
y = number of drinks
b = total costs
⇒ We already know the costs so lets construct the equation.
[tex]5.25x + 1.75y = b[/tex]

What is the nth term rule of the quadratic sequence below?
-5, -3,3, 13, 27, 45, 67, ...
Answer:
the pattern is +2, +6, +10, +14, +18 etc
so its in increment of 4
the rest is trivial
Step-by-step explanation:
Answer:
[tex]u_{n} = 2n^{2} -4n-3[/tex]
Step-by-step explanation:
a +b + c = - 5 First term in sequence
3a + b = 2 Difference between first two terms
2a = 4 Difference between the difference of the first two terms and the second third terms (the difference between -5 and -3 is 2 the difference between -3 and 3 is 6; the difference between 6 and two is 4)
2a = 4 so a = 2; 3(2) + b = 2 → 6 + b = 2 so b = -4; 2 - 4 + c = -5 → -2 + c = -5 so c = -3

Can someone help plz? Jack and Jessica earned the same amount last week. Jack earned $18 per hour and had $41 taken from his check for taxes LaTeX: (18x-41)( 18 x − 41 ). Jessica earned $15 per hour and had $17 deducted from her pay. How many hours did each work in order to get paid the same amount?
Write the equation
Solve for the number of hours
Answer:
the answer is 8
Step-by-step explanation: so first what you want to do is you want to set up the equation 18x-41. then you want to do 15x because of the 15 per hour. then you minus 17. so your equation is 18x-41=15x-17 then the answer to that is 8 hours

In AEB,CD is parallel to AB. Complete each proportion please help!!!!!!!!!!!!
Answer:
see explanation
Step-by-step explanation:
Given a line CD parallel to a side of the triangle and intersecting the other 2 sides, then it divides those sides proportionally, thus
(a)
[tex]\frac{EC}{CA}[/tex] = [tex]\frac{ED}{DB}[/tex]
(b)
[tex]\frac{EC}{EA}[/tex] = [tex]\frac{ED}{EB}[/tex]

Winnie needs to spend $120 on two kinds of fancy cakes:
Chocolate Delight and Coffee Comfort. The Chocolate cake
sells at 12 dollars per slice and the Coffee cake sells at 10
dollars per slice.
If Winnie buys 5 slices of Chocolate cake, how many slices of
Coffee cake does she buy?
___slices
Answer:
Winnie needs to buy 6 slices of Coffee cake.
Step-by-step explanation:
12 * 5= $60 (chocolate cake)
120 - 60= 60
since we know the coffee cake costs $10(per slice) we do:
60/ $10= 6 slices of coffee cake.
what is the equation for the line in slope intercept form plz help ASAP
Answer:
y = - 4x + 5
Step-by-step explanation:
y = mx + b
(0, b) y-intercept
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
~~~~~~~~~~
( - 2, 13)
(0, 5) <----- y-intercept
(3, - 7)
(4, - 11)
m = [tex]\frac{-11+7}{4-3}[/tex] = - 4
y = - 4x + 5
Write an equation in slope-intercept form of the line that passes through the given points.
Answer:
y=3/2x+2
Step-by-step explanation:
The slope is 3/2
To find it find to perfect points or "pretty points" and rise then run, so the point (0,2) is a pretty point and (2/5) is a pretty point to get to this point you rise 3 and run 2, so 3/2.
The y-intercept is 2
To find the y-intercept all you need to do is find the point that passes through the y-axis, so (0,2) the y-intercept would be 2.
