The answer is 133 beats per minute.

To calculate this, we will use proportion.
If 190 beats per minute are 100%, how many beats per minute are 70%:
190 bpm : 100% = x : 70%
\frac{190 bpm}{100} =  \frac{x}{70}
\frac{70 * 190bpm}{100} = x
x = 133 bpm

Thus, Xanthe's target heart rate is 133 beats per minute.

SMART PPL PLEASE HELP ,Explain how you know the expression represents the area of shaded part of the rectangle.
MrRa [10]

Answer:

6(m-2)

Step-by-step explanation:

Alright. Let's start by finding the length of this shaded area. The full length of the rectangle is 'm', and the part that is not shaded has a length of '2', so if we subtract the full length and the non-shaded length, we will get the shaded part's length. This is 'm-2'. The width/height we already know...it is 6, so-

Answer is: 6(m-2)

A whale costs $14700 and depreciates in value by 8% per year. When will the whale be worth $100
sammy [17]

Answer:

x = 60

Step-by-step explanation:

The question is asking

$14,700 * (1 - 8%)^x = $100

$14,700 * (1 - 0.08)^x = $100

$14,700 * (0.92)^x = $100

(0.92)^x = $100/$14,700

log(0.92^x) = log($100/$14,700)

x * log(0.92) = log(0.0068027)

x = log(0.0068027)/log(0.92)

x = 59.85

Since this question is asking in terms of years, we always round up (in this case to 60), as it won't fully be worth $100 by the beginning of the 59th year.
