Answer:

Equation : 35 + 6.40t < 86.20

t = less than 8 hours

Step-by-step explanation:

If t equals the number of hours they can rent the room before going over their set limit, we would add the base amount (35) to the hourly (6.40t) less than 86.20.

So :

35 + 6.40t < 86.20

6.40t < 51.20 (subtract 35 on both sides)

t < 8 (divide 6.40 on both sides)

Caroline resting heart is 52 beats per minute (bpm). When she starts running her heart rate increases 1.25% each second until it
horsena [70]

Answer:74.55 beat per minute

Step-by-step explanation:

Given

Heart beat is 52 beat per minute

i.e. B=\frac{52}{60} beat per sec

If heart rate is increases 1.25 % each sec

suppose B is the heart beat at first second therefore heat beat at 2 nd second

B_2=B+1.25 \% B

B_2=B(1+1.25 \% )

For 3 rd sec

B_3=B(1+1.25\%)+1.25\%B(1+1.25\%)

B_3=B(1+1.25\%)^2

similarly for 3 sec

B_{30}=B(1+1.25\%)^{29}

B_{30}=1.433B

B_{30}=1.242\ \text{beat per second }

B_{30}=74.55\ \text{beat per minute}

A grocer wants to make a 10-pound mixture of peanuts and cashews that he can sell for $4.75 per pound. If peanuts cost $4.00 per
vladimir2022 [97]
The grocer wants to make a 10 pound mixture 
p - pounds of peanuts
c - pounds of cashews
therefore the total pounds should be equal to 10 pounds 
p + c = 10 -----> 1)
the cost for ;
peanuts - 4.00 per pound * p pounds = 4p
cashews - 6.50 per pound * c pounds = 6.5c
the price of 10 pounds mixture = 4.75 per pound * 10 pounds = 47.5
4p+6.5c = 47.5 ---> 2)

to solve for p and c lets use simultaneous equations 
p + c = 10 -----> 1)
4p+6.5c = 47.5 ---> 2)
multiply 1st equation by 4
4p + 4c = 40 ---> 3)
subtract 3rd equation from the 2nd
2.5c = 7.5
c = 3
substituting c= 3 in 1st equation
p+c = 10
p+3 = 10
p = 7
therefore 3 pounds of cashews and 7 pounds of peanuts are needed to make the mixture
