It is given in the question that
Emily’s last water bill listed a previous reading of 7,123 ccf and a present reading of 7,171 ccf. Her water company charges $0.73 per ccf of water.
Therefore number of ccf is
And company charges $0.73 per ccf.
So for 48 ccf, company charges
And that's the required answer .
Answer:
The simplification of the given expression (r3s2t)4 is:
r¹²s⁸t⁴
Step-by-step explanation:
Given expression:
(r³s²t)⁴
power of '4' on the whole term will be applied to individual terms after we open the brackets. In this case the power on the whole term will be multiplied to the power of each individual term:
= (r³)⁴(s²)⁴(t1)⁴
= r³ˣ⁴ s²ˣ⁴ t¹ˣ⁴
= r¹²s⁸t⁴
<span>Equation A: 4c = d − 8
</span><span>Equation B: c = 5d + 8
</span>
Multiply Equation A by -5:
Equation A: - 20c = -5d + 40
Equation (1) + (2) :
-19c = 48
Answer: <span>B. Multiply equation A by -5</span>
<span>|4x + 12| = 16
As it is in modulus function, it could be either +ve or -ve
4x+12 = 16 OR 4x - 12 = 16
4x = 16-12 OR 4x = 16 + 12
4x = 4 OR 4x = 28
x = 4/4 OR x = 28/4
x = 1 OR x = 7
In short, Your Answer would be either 1 or 7
Hope this helps!</span>
Answer:
To find a
sin 30=a/6in
1/2=a/6in
2a=6in
a=6in/2
a=3in
To find b
cos 30=b/6in
/3/2=b/6in
2b=/3*6in
b=2/3(two radical three)
I don't get the radical sign so I use / sign on the last 3 steps on the second
