STEM In 10 minutes, a heart can beat 700 times. At this rate,
in how many minutes will a heart beat 140 times? At what rate.
can a heart beat? (Example 4)

Answers

Answer 1

According to the average rate, Heart can beat 140 times in = 2 minutes and Rate of heart beat= 70 beat per minute .

According to the statement

We have to find that the rate of the heart beat.

So, For this purpose, we know that the

Average rate is a measure of how much the function changed per unit, on average, over that interval.

From the given information:

In 10 minutes, a heart can beat 700 times. At this rate,in how many minutes will a heart beat 140 times?

Then

Heart can beat 700 times in = 10 minutes .

Heart can beat 140 times in = 10*140/700 minutes .

Heart can beat 140 times in = 1400/700 minutes .

Heart can beat 140 times in = 2 minutes .

Rate of heart beat : 140/2 beat per minute.

Rate of heart beat= 70 beat per minute .

Therefore, According to the average rate, Heart can beat 140 times in is 2 minutes and Rate of heart beat is 70 beat per minute.

Point Q is the midpoint of segment PR. QR = 18 and PR = 5x+6.

Answers

Applying the definition of the midpoint of a segment, we have:

x = 6

PR = 36 units

What is the Midpoint of a Line Segment?

If point Q is the midpoint of segment PR, it therefore means that point Q bisects (divides) line segment PR into two equal parts, namely: PQ = QR.

Also, PQ + QR = PR

Given the following:

QR = 18

PR = 5x + 6

Thus, we can create the following equation:

2(QR) = PR

Substitute

2(18) = 5x + 6

36 = 5x + 6

36 - 6= 5x + 6 - 6

30 = 5x

30/5 = 5x/5

6 = x

x = 6

PR = 5x + 6

Plug in the value of x

PR = 5(6) + 6

PR = 36 units

I use a prime factor analysis (identify all the prime factors).

54 = 2×3³

the largest number that can divide them both without remainder is the combination of the prime factors they have in common :

#SPJ1

Answer:

A. 26 = 13.5 + m/2.5; m = 5 is the correct equation and solution.

To explain, the word "quotient" indicates that we need to divide a number by 2.5. Let the unknown number be represented by the variable "m". Then, the quotient of a number and 2.5 can be written as m/2.5. The math sentence can be written as: 26 = 13.5 + m/2.5

To solve for "m", we can isolate it by subtracting 13.5 from both sides and then multiplying both sides by 2.5:

26 - 13.5 = m/2.5

12.5 = m/2.5

m = 12.5 * 2.5

m = 5

Therefore, the equation that represents the given math sentence is 26 = 13.5 + m/2.5, and the solution is m = 5. Option a is correct.

What is the y-intercept of a function?

The y-intercept of a function is the value of f(x) when x = 0, that is, the value of y for which the function crosses the y-axis.

If the function crosses the y-axis at y = 0, it will have a y-coordinate of 0, hence:

In linear equations, the possible number of players in a game with eight teams  is given by 16 ≤ P ≤ 32.

What are instances of linear equations?

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is rather simple (x and y).

Let the number of players be n

Since each team can have between 2 and 4 players

n ≥ 2 or 2 ≤ n, and n ≤ 2

Therefore, the allowable number of players on a team   is given by 2 ≤ n ≤ 4

2) There are four players in Han's team and a perfect score is 20

Therefore, the number of points Han's team earns in one round if every player earns a perfect score   is given by 4 * 20

3) There are four players in Han's team

Total score if each player in Han's team earns a perfect score is 4 * 20 = 80

Let the total score of Han's team be T

Therefore, the number of points, Han's team earns in one round if no players earn a perfect score   is given by T < 80

4) If two team have 4 players, it is given by 2 * 4

If the rest four teams have 3 players each, it is given by 4 * 3

Therefore, the number of players in a game with six teams of different sizes: two teams have 4 players each and the rest have 3 players each  is given by (2 * 4) + (4 * 3)

5) Let the possible number of players in a game with be P

Maximum number of players in eight teams = 4 * 8 = 32

Minimum number of players in eight teams = 2 * 8 = 16

P ≤ 32 and P ≥ 16 or 16 ≤P

Therefore, the possible number of players in a game with eight teams  is given by 16 ≤ P ≤ 32.

Percentage that are high school students; 40% = 0.4

Percentage of high school students who chose dancing; 6% = 0.06

Thus, Percentage of high school students who chose watching movies/TV = 0.4 - (0.22 + 0.06) = 0.12

Percentage that are college students; 100% - 40% = 60% = 0.6

t=5s+50c   ==> c=2

t=5s+50(2)

t=5s+100

5 is the cost of making each shirt and 50 is the cost of making shirts in one color. Hence, 50c is the cost of making shirts in c number of colors and 5s is the cost of making s number of shirts. 50c translates to 50(2) since shirts are made in two colors, so 50(2)=100. 100 dollars is the total cost of making shirts in 2 different colors.

Considering the sum of the internal angles of the polygon, it is found that the measures of the angles A and B are given as follows;

Angle A: 119º.Angle B: 93º.

What is the sum of the internal angles of a polygon?

The sum of the internal angles of a polygon with n vertices is given by the following equation:

S = (n - 2) x 180º.

For this problem, the polygon has 6 vertices, hence n = 6 and the sum is given by:

S = (6 - 2) x 180º = 720º.

Considering each internal angle, we can solve for x as follows:

13x + 2 + 16x + 7 + 88 + 155 + 170 + 95 = 720

29x + 517 = 720

29x = 203

x = 203/29

x = 7.

Then the measures are given as follows:

Angle A: 16 x 7 + 7 = 119º.Angle B: 13 x 7 + 2 = 93º.
