This sign shows when a lift is safe to use.
Total mass of people must be 480 kg or less
Fred and some other people are in the lift and their total mass
is 565 kg to the nearest 5 kg.
Fred, who has a mass of 88 kg to the nearest kg, gets out of the lift.
Is the lift now safe to use?
You must show your working and clearly state 'Yes it is safe' or 'No it is not safe'
Answer:
Yes it is safe
Step-by-step explanation:
lower bound of fred's weight (88kg) = 87.5kg
upper bound of total mass (480kg) = 567.5 kg
567.5kg - 87.5kg = 480 kg
The total mass in the lift after Fred gets out is [tex]477[/tex] kg which is less than the safe limit of [tex]480[/tex] kg. So, the lift is safe to use.
Maximum mass in the lift [tex]= 480[/tex] kg.
Total mass of Fred and other people in the lift [tex]= 565[/tex] kg.
Mass of Fred, in nearest kg, [tex]= 88[/tex] kg.
Fred gets out of the lift. So, subtract the mass of Fred from the total mass in the lift.
Total mass of people in the lift [tex]= 565-88 = 477[/tex] kg, which is less than safe limit of mass in the lift.
So, the lift is safe to use now.

Cost of cashews cost $2 more than peanuts. Gabriel orders 4 cans of cashews and 3 cans of peanuts the total cost was $56. Write an equation for the cost of peanuts
Answer:
3x = 56 - (4x + 8)
Step-by-step explanation:
Let
Cost of peanut = x
Cost of Cashew = x + 2
Total Cost = Cost of Cashew + Cost of peanut
56 = (x+2) * 4 + x * 3
Cost of peanut: 3x = 56 - (4x + 8)
Total Cost = Cost of Cashew + Cost of peanut
56 = (x+2) * 4 + x * 3
56 = (4x + 8) + 3x
56 = 4x + 8 + 3x
56 = 7x + 8
56 - 8 = 7x
48 = 7x
x = 48/7
x = 6.86

A force of 450 N is exerted with a pressure of 15 N/m2.
Calculate the area to which the force has been applied.
134356377489486467347
Step-by-step explanation:
Force (F) = 450 N
Pressure (P) = 15 N/m² or 15 pa
Area (A) = ?
We know the force acting normally per unit area is pressure so,
P = F / A
15 = 450 / A
A = 450 / 15
A = 30 m²
The area to which the force has been applied is 30 m².

Calculate the indicated function values in the following problems. Simplify your answers.
Answer:
14) [tex]f(10) = 10[/tex], 15) [tex]f(-2) = -2[/tex], 16) [tex]f(a) = a[/tex], 17) [tex]f(a+b) = a+b[/tex], 18) [tex]g(10) = 38[/tex], 19) [tex]g(-2) = -22[/tex], 20) [tex]g(a) = 5\cdot a - 12[/tex], 21) [tex]g(a+b) = 5\cdot a +5\cdot b -12[/tex]
Step-by-step explanation:
Let [tex]f(x) = x[/tex] and [tex]g(x) = 5\cdot x - 12[/tex], we proceed to resolve on each case:
14) [tex]f(10)[/tex]
[tex]f(x) = x[/tex]
[tex]f(10) = 10[/tex]
15) [tex]f(-2)[/tex]
[tex]f(x) = x[/tex]
[tex]f(-2) = -2[/tex]
16) [tex]f(a)[/tex]
[tex]f(x) = x[/tex]
[tex]f(a) = a[/tex]
17) [tex]f(a+b)[/tex]
[tex]f(x) = x[/tex]
[tex]f(a+b) = a+b[/tex]
18) [tex]g(10)[/tex]
[tex]g(x) = 5\cdot x - 12[/tex]
[tex]g(10) = 5\cdot (10) -12[/tex]
[tex]g(10) = 38[/tex]
19) [tex]g(-2)[/tex]
[tex]g(x) = 5\cdot x - 12[/tex]
[tex]g(-2) = 5\cdot (-2) -12[/tex]
[tex]g(-2) = -22[/tex]
20) [tex]g(a)[/tex]
[tex]g(x) = 5\cdot x - 12[/tex]
[tex]g(a) = 5\cdot a - 12[/tex]
21) [tex]g(a+b)[/tex]
[tex]g(x) = 5\cdot x - 12[/tex]
[tex]g(a+b) = 5\cdot (a+b) -12[/tex]
[tex]g(a+b) = 5\cdot a +5\cdot b -12[/tex]
A hot air balloons height varies directly as the balloons ascents the time in minutes. A hot air balloon rises at 350 feet in five minutes. Write a direct variation equation.
Answer:
h α t
h = kt
k = h/t
350 = k5
350/5 = k
k = 70
Step-by-step explanation:
Given that :
Ballon height varies directly as the Ascent time in minutes
Height of hot air Ballon rises 350 feets in 5 seconds
Expressing as a direct variation :
Let height of Ballon = h
Time it takes to rise = t
h α t
h = kt
k = h/t
350 = k5
350/5 = k
k = 70
