1. 30/23, do the math, if you cant do simple math, use a calculator
2a. 2.60 x 35 = distance of the laps together
t = d/s
t = distance of the laps ÷ 182m/h
2b. You have the info, do it urself
3a. 30 x 6. Not that hard, giving you hints here
3b. Look at the answer at 3a, now look at what your friend wrote. Clearly he/she listened to some dumb person on brainy
4. s = d/t
s = 22/30. Again, use a calculator
I did basically all the work for you. Just get up your lazy butt to get a calculator. Not that hard! I probably am smaller and younger than you!
I better get brainilest for this...
You're welcome :)
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx
where
k is the constant of proportionality
Verify each table
table a
Let
x ----> distance
y ----> sound level
For each ordered pair calculate the value of k
k=y/x
so
(5,85) -----> k=85/5=17
(10,79) ----> k=79/10=7.9
the values of k are differents
that means
the table nor represent a proportional relationship
table b
let
x ----> volume
y ----> cost
k=y/x
(16,1.49) ----> k=1.49/16=0.093125
(20,1.59) ----> k=1.59/20=0.0795
the values of k are differents
that means
the table nor represent a proportional relationship
Answer:
0
Step-by-step explanation:
while rounding the fraction to half,it is to remember that
anything less than 1/4 can be rounded to zero.
anything equal or 1/4 or greater and less than 3/4 can be rounded to 1/2.
anything greater than 3/4 and less than 1 can be rounded to one.
so,1/9<1/4
the value is 0.
You need to find the surface area and the volume. The formula for surface area is 4*3.14(pi)*radius^2 which is equal to 6.5144 inches^2 in this case. The amount of rubber needed to fill it is equal to the volume. The formula for volume of a sphere is 4/3*3.14(pi)*radius^3, just plug in the number (remember radius is half of diameter) and that will give you the answer!
