a person's heart beats approximately 10^5 times each day. a person lives approximately 81 years. Work out an estimate for the number of times a person's heart beats in their lifetime

Answers

Answer:

29565x(10^5)

Step-by-step explanation:

heartbeat in 1 day=10^5.

we have 365 days in a year. it means that;

365x(10^5)=365x(10^5). this is heartbeat for 1 year.

then for 81 years,we multiply the value of 1 year heartbeat by 81.

=29565x(10^5).

solve for the value of c

The green parallelogram is a dilation of the black parallelogram. What is the scale factor of the dilation?
A) 1/3
B) 1/2
C) 2
D) 3

Answers

Answer:  B)  1/2

=============================================================

Explanation:

"The green parallelogram is a dilation of the black parallelogram"

This tells us that the preimage is the black parallelogram and the image is the green one.

In short, the mapping is [tex]\text{black} \to \text{green}[/tex]

The image is smaller than the preimage (green is smaller than black), indicating the scale factor is some value of k such that 0 < k < 1. We can rule out choices C and D because of this.

--------------------

Measuring along the top, we can see that the black parallelogram goes from x = -6 to x = 8. Check out the image shown below where I've marked your given diagram, adding on helpful lines to show this going on.

The number-line distance from x = -6 to x = 8 is 14 units, so the top side of the black parallelogram is 14 units long.

The corresponding top side of the green parallelogram is 7 units long (because it spans from x = -3 and x = 4; as shown in blue in the figure below).

Divide the image length over its corresponding preimage length to get the scale factor.

scale factor = (image length)/(preimage length)

scale factor = 7/14

scale factor = 1/2

which points to choice B as our final answer.

Answers

Answer:

Step-by-step explanation:

[tex]1)\ 180 - 121.8 = 58.2[/tex]

[tex]2)\ angle\ 2 = 58.2 - 17.3 = 40.9[/tex]

Answer:

m∠1  = 67.4°      m∠2 = 104.5°

Step-by-step explanation:

17.3 + m∠2 = 121.8

m∠2 = 104.5°

m∠1 + 37.1 = m∠2 = 104.5

m∠1  = 67.4°

Which of these best describes π? A The area of a circle divided by its diameter. B The circumference of a circle divided by its radius. C The circumference of a circle times 3.14 D The ratio of a circle's circumference to its diameter

Answers

Answer: D. The ratio of a circle's circumference to its diameter

Step-by-step explanation:

Pi is the ratio of the circumference of a circle to its diameter which means that we get pie by dividing the circumference by the diameter. This relationship is true regardless of the size of the circle because the relationship between the circumference and the diameter does not change regardless of size.

Pi is very useful when calculating measures related to circles such as area and circumference. It also comes in handy for shapes that have circles in them such as cones.

Answer: 91.65

Part 1: You will need to find the average by adding 108, 72, and 95. This will give you 275. Now you divide the sum by the amount of numbers there are which is 3 numbers. 275/3 would be 91.6

Part 2: Now that you have all four numbers you should repeat the process, 108 + 72 + 95 + 91.6 which is 366.6 now divide by four, and you have 91.65.

Answers

Answer: 195 CM

Step-by-step explanation:

Volume: Length x Width x Height

“First we have to break it into 2 shapes”

“Let’s solve the top shape!!”

The length is 5 the width is 3 and the height is 4.

Volume = 5 x 3 x 4 = 60

Now the bottom shape

The length is 9 the Width is 5 and the Height is 3

The height isn’t given so we must do some math

Subtract the 7 from 4 = 7 - 4 = 3

Volume = 9 x 5 x 3 = 135

Finally, 135 + 60 = 195 cm

In circle D with m \angle CDE= 122m∠CDE=122 and CD=6CD=6 units, find the length of arc CE. Round to the nearest hundredth.

Answers

Answer:

12.78 units

Step-by-step explanation:

The formula for arc length =

2πr × θ/360

From the question:

θ = 122°

r = 6 units

Therefore, the arc length =

2 × π × 6 × (122/360)

= 12.775810125 units

Approximately to the nearest hundredth = 12.78 units

Therefore, the length of arc CE is 12.78 units

An isosceles triangle has an angle that measures 110°. Which other angles could be in that isosceles triangle? Choose all that apply: 110 55 35 15

Answers

Answer:

35 degrees

Step-by-step explanation:

An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side

sum of angles in a triangle = 180

180 - 110 = 70

since 2 angles would be equal

70 / 2 = 35
