Answer:
a-b=10
Step-by-step explanation:
add all the numbers then round
13+ 14+ 22+ 52+ 63+ 77=241
Round to the nearest ten
a =240
first rounding each number to the nearest ten and then add
13+ 14+ 22+ 52+ 63+ 77
10+10+20+50+60+80 =230
b= 230
a-b = 240-230
= 10
Answer:
Kayla bought 7 tacos and 10 hotdogs
Step-by-step explanation:
Let the number of hotdogs be x.
Let the number of tacos be y.
i) It is given that x = y + 3
ii) It is also given that 3.5x + 4y = 63, therefore 7x + 8y = 126
iii) substituting the value of x from i) in ii) we get 7(y + 3) + 8y = 126
therefore 15y + 21 = 126
therefore 15y = 105
therefore y = 7
Therfore Kayla bought 7 tacos
iv) Using the value of y from iii) in i) we x = 7 + 3 = 10
Therefore Kayla bought 10 hotdogs

I hope this helps :)
V=hpir^2
I will assume that the first one is the one with radius 16 and height 40
2nd is radius 7 and height 26
1. v=hpir^2
v=40pi16^2
v=40pi256
v=10240pi cubic inches
3rd option
2.
v=hpir^2
v=26(3.14)7^2
v=26(3.14)(49)
v=1274(3.14)
v=4000.36 cubic cm
1st option
