Answer:

The answer is photo.

Step-by-step explanation:

So:

167 - 66 = 101

So the total of Spain is 101

Now what is Marc’s value for Spain?

33 + 40 = 73

101 - 73 = 28

Marc’s value is 28.

Elli’s value for Portugal is unknown. We know Elli’s total is 57 and her value for Spain is 40. So: 57 - 40 = 17.

Elli’s value for Portugal is 17.

Now what is Marc’s total?

We know Spain is 28 and Portugal is 24. So add them:

28 + 24 = 52

Marc’s total is 52.

Now, what is Raisa’s total. We everyone else’s total and we know it all adds up to 167 so:

57 + 52 = 109

167 - 109 = 58

Raisa’s total is 58.

What is her Portugal value?

58 - 33 = 25

Her Portugal value is 25.

Aime hiked for 3 days across an island. He started at the shoreline, which is at an elevation of 0 feet. At the end of day 1, Ja

koban [17]

Answer:

4120 feets

Step-by-step explanation:

Given that:

Starting elevation = 0 feets

Elevation gained on first day = 2150 feets

Total elevation at the end of day 1 = 0 + 2150 = 2150 feets

Elevation gained on second day = 1970 feets

Total elevation at the end of day 2 = 2150 + 1970 = 4120 feets

Elevation at the end of 3 rd day = 0 feets

Hence, elevation lost on day 3 ;

(4120 - 0) = 4120 feets

The Baker formula estimates the maximum heart rate, in beats per minute, of a person who is

seropon [69]

Answer:

For a=16, the Maximum Heart Rate is 188 Beats Per Minute.

Step-by-step explanation:

To begin, we know that the formula:

$b(a)=200-0.75a$ Eqn(1).

is equivalent to a linear equation of algebraic form denoted as:

$y=k+mx$ Eqn(2)

as such that Eqns (1) and (2) relate as follow:

$y$ ⇔ $b(a)$ : denoting our Dependent Variable, in this case Max. Heart Rate in Beats Per Minute

$x$ ⇔ $a$ : is our Independent Variable, in this case the Age of the Person

$m$ ⇔ $0.75$ : denoting the Rate of Change of the Age.

$k$ ⇔ $200$ : denoting our Constant.

Now in the question our value of $b(a)$ is given as 188 beats per minute, which by plugging in Eqn(1) gives:

$200-0.75a=188$

from which we can solve to obtain the value of $a$ as follow:

$-0.75a=188-200$ Gather similar terms on each side

$-0.75a=-12\\$ Simplify

$a=\frac{-12}{-0.75}$ Solve for $a$

$a=16$

Which tells us that at the Age of 16, the Max. Heart Rate is 188 Beats Per Minute.

Answer:

Option (2)

Step-by-step explanation:

Standard form of the polynomial will be in the form of (ax⁴+ bx³+ cx²+ dx + e).

Which means exponents of each successive term will be in the reducing form and the last term will be a constant term.

Now we can rearrange the terms of the given polynomial (5x + 2x⁴ - 4) for the standard form.

(2x⁴ + 5x - 4)

Since, degree of the leading term = 4

And number of terms = 3

Given polynomial is a fourth degree trinomial.

Option (2) will be the answer.

Answer:

Your answer is B) 3.6 cm.

Step-by-step explanation:

10 mm = 1 cm. To convert 36 mm to cm all you have to do is divide by 10.

36/10 = 3.6

So, 36 mm = 3.6 cm.

In the future, if you were to convert cm to mm, just multiply by 10.
