Answer:
a: 120m
b:rs. 9000
Step-by-step explanation:
Lenght:35m
Breadth:25m
Lenght of wooden strip required to frame(perimeter) = 2(L + B)
=2(35m +25m)
= 2(60m)
= 120m
Cost of wooden strip =Rs.75/m
Total cost= length of wooden strip × cost
= 120m × Rs.75/m
= Rs. 9000
Answer:
43100
Step-by-step explanation:
A rectangular one-story house covers an area of 3,700 square feet. The ceilings are 8 feet high. The owners add a second floor to the house. The second floor is 50 feet long and 30 feet wide with ceilings that are 9 feet high. What is the total volume of the interior of the house?
Volume = length x width x height
or volume = area x height
Volume of the one- storey = 3700 x 8 = 29600 square feet
Volume of the second floor = 50 x 30 x 9 = 13500 square feet
volume of interior = 29600 + 13500 = 43100 square feet
Answer:
2.35 yards/second or 7.07 ft/second
Step-by-step explanation:
The distance to be covered is 55 yards.
The casting cools at the rate of 
and the temperature must not be allowed to cool more than 
.
We know that, 
By the time, the temperature reaches , it will take about,
, so it will take about 23.33 seconds.
Also, 55 yards = 
So the minimum speed that conveyor must move is,
Hence, the speed of conveyor is 7.07 feet per second.
Answer:
2
Step-by-step explanation:
given the difference of twice a number and one is three to find "number" let the number be x
2x - 1 =3
2x = 4
x= 2
thus the number is 2
Answer:
Step-by-step explanation:
from the graph of f(x)
when x=1,f(x)=0
or f(1)=0
when f(x)=2,x=2
for g(x)
when x=6,g(x)=16
or g(6)=16
when g(x)=18,x=32
for h(x)
when x=14
h(x)=27x-7
h(14)=27×14-7=7(27×2-1)=7(54-1)=7×53=371
h(x)=-493
27x-7=-493
27 x=-493+7=-486
3 x=-54
x=-18
for p(t)
when t=94
p(t)=24
p(94)=24
p(t)=67
t=31
