Are heart rate and age proportional or non proportional for each method

Answers

Answer 1

Answer:

Yes

Step-by-step explanation:

For example

Doctors have two methods of calculating maximum heart rate. With the first method, maximum heart rate, y, in beats per minute is y=220−x, where x is the person’s age.

Answer:

92 ...... .......... ..........

Answer:

348 square units

Step-by-step explanation:

Let's find the area of the front, the bottom and the end:

(9)(6) + (9)(8) + (6)(8) = 54 + 72 + 48 = 174 square units

Since there are two of each of these areas, double 174 to obtain 348 square units

in Mike’s house are broken now. His father replaced 3/14 of the broken) .4 windows. Uncle Jack replaced 1/7 of the broken windows. Who replaced the greater fraction of the broken windows?

Answers

Answer:

Mike's father produces a greater fraction.

Step-by-step explanation:

Amount of windows replaced by Mike's father = 3/14

Amount of windows replaced by Uncle Jack = 1/7

This 1/7 can also be expressed as 2/14

Now, since they both have the same denominators, it means that the higher the numerator the greater than the other fraction.

Thus, 3/14 is greater than 2/14.

Hence, Mike's father replaced a greater fraction of the broken windows.

Write in Slope Intercept form

Answers

Answer:

its the first choice

Step-by-step explanation:

Answer:

y=  -3/5x +5

Step-by-step explanation:

Step one - find where the line is intercepting. In your case this is at positive 1.

Next step is to check the change of the slope - directio.  The line goes up to the positive Y access  and to the left of the negative X access.

That leads to a negative slope.

Respectavley the only posible  answer on this question is  

y=  -3/5x +5

Good luck.

Here are some values of sequence Q. Write a recursive definition for the sequence.

n Q(n)
1 3
3 8
7 18​

Answers

Answer: Q(n) = Q(n - 1) + 2.5

Step-by-step explanation:

We have 3 values of the sequence Q(n)

These values are:

Q(1) = 3

Q(3) = 8

Q(7) = 18

I would think that this is a geometric sequence.

Remember that the equation for the n-th term of a geometric sequence is:

A(n) = A(1)*r^(n-1)

where r is a constant, and A(1) is the first term of the sequence.

If we rewrite the terms that we know of Q(n) in this way we get:

Q(3) = Q(1)*r^(3 - 1) = 3*r^2 = 8

Q(7) = Q(1)*r^(7 - 1) = 3*r^6 = 18

Then we have two equations:

3*r^2 = 8

3*r^6 = 18

We should see if r is the same for both equations:

in the first one we get:

r^2 = 8/3

r = (8/3)^(1/2) = 1.63

and in the other equation we get:

r^6 = 18/3

r = (18/3)^(1/6) = 1.34

Then this is not a geometric sequence.

Now let's see if this is an arithmetic sequence.

The n-th term of an arithmetic sequence is written as:

A(n) = A(1) + (n - 1)*d

where d is a constant.

If we write the terms of Q(n) that we know in this way we get:

Q(3) = Q(1) + (3 - 1)*d = 3 + 2*d = 8

Q(7) = Q(1) + (7 - 1)*d = 3 + 6*d = 18

We need to see if d is the same value for both equations.

in the first one we get:

3 + 2*d = 8

2*d = 8 - 3 = 5

d = 5/2 = 2.5

In the second equation we get:

3 + 6*d = 18

6*d = 18 - 3 = 15

d = 15/6 = 2.5

d is the same for both terms, then this is an arithmetic sequence.

An arithmetic sequence is a sequence where the difference between any two consecutive terms is always the same value (d)

Then the recursive relation is written as:

A(n) = A(n - 1) + d

Then the recursive relation for Q is:

Q(n) = Q(n - 1) + 2.5

A group of people attempt to bake the largest vegan cake the used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. How many kilograms of cocoa powder and dates do they use?

Answers

Answer: 187 kilogram

Step-by-step explanation:

Let the kilogram of dates be represented by x.

Since they used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. The dates will be:

= 1/10 × x = 17

0.1x = 17

x = 17/0.1

x = 170 kilogram

Date = 170 kilogram.

Cocoa powder = 17 kilogram

The total kilogram of date and cocoa powder used will be:

= 170 + 17

= 187 kilogram

The old bag of marbles contains 4 blue and 3 red marbles. If you were to double the number of red and blue marbles to create a NEW bag, would the chance of pulling out a blue marble be the same as pulling a blue marble from the old bag? (this is for math class by the way-)

Answers

Answer:

The chance will be the same (4/7)

Step-by-step explanation:

Old bag

p(blue)=4/7

New bag

p(blue)=8/14=4/7

The chance will be the same (4/7) since both the red and the blue marbles are doubled at the same time implying that the ration of red to blue still remails the same.
