First take the fractions and find their common denominator:

x 4 =

Now you can add the fractions:

Now add your whole numbers and the fraction:
1+1= 2 >> 2+

= 2

yards
Now subract 2

from 5:
5-2

=
2
yards
Volume of a cylinder of radius r and heigth h is

Here h is 15 cm and r is 6 cm.
Answer:
80x
Step-by-step explanation:
If you pay 80 a month then to find the total you have paid after any number of months you would multiply amount times time which in this case is 80
a constant is the a number on its own so in this case there would be none
a coefficient is the number in front of a variable. Since the equation is 80x the coefficient is 80
Answer:
The degrees of freedom associated with the critical value is 25.
Step-by-step explanation:
The number of values in the final calculation of a statistic that are free to vary is referred to as the degrees of freedom. That is, it is the number of independent ways by which a dynamic system can move, without disrupting any constraint imposed on it.
The degrees of freedom for the t-distribution is obtained by substituting the values of n1 and n2 in the degrees of freedom formula.
Degrees of freedom, df = n1+n2−2
= 15+12−2=27−2=25
Therefore, the degrees of freedom associated with the critical value is 25.
<u>Solution:</u> 48cm/s^2
<u>Working:</u>
A = s^2
Derivate s^2 (as it is area formula) which gives
dA/dt = 2s dL/dt
dL/dt = 6cm/s
Hence,
2(6) = 12
Side: 4cm
Hence,
dA/dt = (4)(12) = 48cm/s^2
