Answer:
$ 10.69
Step-by-step explanation:
225 is 2.25 times the 100 pencils. ( 225/100) So all you have to do is multiply 2.25 the price ($4.75) and you get 10.6875, money can only go to the tenth place so you round it to $10.69

Answer:
8 weeks
Step-by-step explanation:
Amount saved from mowing lawns = $433 - $145
= $288
Number of weeks to save $288 from $36 a week = 288/36 = 8 weeks
2/3 * 2 = 4/6
4/6 + 1/6 = 5/6
1 - 5/6 = 1/6
750*6 = 4500
Hope this helps! :)

Raul's cost per unit for each paragraph reads is
page points, that's why the model a link with the same unit rate. please find the graph in the attached file.
Answer:
The rate of change of blood pressure at the 50-pound weight level is 0.26
The rate of change of blood pressure at the 80-pound weight level is 0.16
Step-by-step explanation:
We have, P(x) = 12.9(9 + ln x)
We need to compute the rate of change of blood pressure P(x) so, we will differentiate the function P(x) with respect to x.
P(x) = 12.9(9 + ln x)
P(x) = 116.1 + 12.9ln x
Differentiating with repect to x:
= 0 + 12.9 (
)
= 12.9 (
)
The differential of ln x is
and the differential of constant terms is 0.
The rate of change of blood pressure at the 50-pound weight level can be calculate by substituting 50 in place of x, so
= 12.9 (
)
= 12.9 * (1/50)
= 0.258
= 0.26
Similarly, The rate of change of blood pressure at the 80-pound weight level can be calculate by substituting 80 in place of x, so
= 12.9 (
)
= 12.9 * (1/80)
= 0.16125
= 0.16
