Answer:
Yes, the bill is absolutely accurate
Step-by-step explanation:
Cost of materials= $ 678.12
Final bill amount(given)=$1206.12
Rate= $32 per hour for 16.5 hrs
Total amount for 32 hrs = time * rate = 16.5* 32=$528
Therefore, by the problem ,
<em>Cost of materials+ Total amount for 32 hrs = Final bill amount</em>
= 678.12+ 528
=1206.12
<u>Therefore , the final bill amount is 100% accurate as it completely matches with the given bill amount</u>
Answer:
The answer is $4.10
Step-by-step explanation:
If 3 pounds = $1.23
1 pound =1.23/3
= 0.41
Therfore 10 pounds = 10× 0.41 = $4.10
C = 2r in terms of r is
C/2 = r
The answer is C/2 = r
Y = mx + b is slope-intercept form.
"m" is the slope and "b" is the y-intercept.
The slope, 5/4, is in place for "m".
All you will need to do is graph the problem, so either graph a point starting at <span>(−8, −7) that uses a rise of 5 and run of 4, or go to desmos graphing (the best graphing website in my opinion).
I will attach an image of the graph, where we see the y-intercept is (0, 3).
This means our final answer is
y = 5/4x + 3.</span><span>

Yes, the two ratios are proportional to each other. The multiplier from the first ratio to the second ratio is 3. For example, 4.2 x 3 = 12.6 and 1.5 x 3 = 4.5. Basically, to figure out if two ratios are proportional to each other, just divide the smaller number into the bigger number for both corresponding numbers. If they're the same ---> Proportional. If they're not the same ---> Not Proportional
