Answer:
324
Step-by-step explanation:
The shirt would be the same value because they are the same so
288÷3=96
Pi Shirt = 96
then work out the 3rd one to find out the balloons
98+ balloon + balloon= 226-96=130÷2= 65
Balloons = 65
then work out the 2nd one 195÷65=3
Pizza = 3
Then 4th one
25+1=26-3=29
Maccoroni = 29
Last question
96×3+65-29=324
Answer:
15 hours.
Step-by-step explanation:
20 can be divided into quarters, 3 quarters is 15/20 hours.
Answer:
mean= sum of all observations /no.of observation
mean=45+80+15+10+94/5
mean=244/5
mean=48.8
this is how the calculator gets 48.8
That is height
h=16t^2+16t+480
when h=0 is when it hits the water
0=16t^2+16t+480
undistribbute 16 for ease
0=16(t^2+t+30)
16*0=0 so assume
t^2+t+30=0
factor
(t+6)(t-5)=0
set to zero
t+6=0
minus 6
t=-6
false, since you cannot have negative time
t-5=0
add 5
t=5
at t=5 she hits the water
5 seconds
1. combine like terms (2x and -7x) to create -5x
2. subtract 5 from each side to create: -5x=10
3. divide both sides by -5
4. x=-2
