I can not use my calculator because my PC is going too slow. But what you do is add up 4+3+4+5+6+6+8+4 and divide it all by 8 (8 being the total numbers in all. That is how you solve all means.)
Answer:
131.88
Step-by-step explanation:
Volume of cylinder: pi r^2h
D=2r=6
R=3
V=3^2x3.14x7=131.88
(x`-b/2a)-D/4a
(x`-7)+576
answer! (7;-576)
Answer:
Emilia bought 28 sweets
Step-by-step explanation:
now they have 65, but before they had 65-15+10 because earlier, zakiah had ten more sweets than now and Emilia had 15 less, so basically, if you wanna calculate number of sweets they had earlier, you have to make minus from plus and in reverse too.
65-15+10=60 and now just do that simply ratio
E:Z=7:8
E+Z=7x+8x
60=15x
4=x
7x=28=Emilia
8x=32=Zakiah
Accuracy test:
(28+15)+(32-10)=65
28 is 4•7 and 32 is 4•8
Answer:
ANSWER: she worked 11 hours at the fast food restaurant and 5 hours helping her aunt
Step-by-step explanation:
First we are going to try to find how many hours she worked on the fast food restaurant so you multiply 4.25 time 16 and x
10.50x + 4.25(16-x) =136.75
10.50x + 68 - 4.25x= 136.75
Then, you subtract 68 from both sides and subtract 4.25x from 10.50x
6.25x=68.75
Divide
X=11 that is how many hours she worked at the FAST FOOD RESTAURANT
Then 16-11 and that gives us how many hours she helped her aunt.
