Do 65/100. Gives you 0.65 right.
So then do 0.65*40 = 26
Answer is 26 minutes.
<span>The expression for the total price paid for all snacks (P pence)= 4n Pence
will be; P=4n.
Calculation:
let the total price for the four snacks be P pence.
let the four snacks be s1,s2,s3, and s4;
their prices are:
s1=n pence; s2= n pence; s3=n pence; s4= n pence.
therefore;
the total price paid for all snacks (P pence)= s1 price +s2 price +s3 price +s4 price = n+n+n+n= 4n
hence; P=4n
i.e. the total price paid for all snacks (P pence)= 4n Pence</span>
Answer:
5 cm approx
Step-by-step explanation:
Given data
Diameter= 20cm
radius= 10cm
Volume= 1570cm^3
We know that the expression for the volume of the container/cylinder is
V= πr^2h
1570= 3.142*10^2*h
1570=3.142*100*h
1570=314.2h
h= 1570/314.2
h=4.99 cm
Hence the height is 5 cm approx
4/5 because the equation is y=mx+b
m= slope = 4/5
I hope that makes sense
