A healthy human heart beats about 1,533,000 times a year. A sparrow's heart beats about 2,417,760,000 times in a year. About how many times faster does the sparrow's heart beat compared to the human heart? Show your work.

Answers

Answer: 1577.14

Step-by-step explanation:

From the question, we are informed that a healthy human heart beats about 1,533,000 times a year and that a sparrow's heart beats about 2,417,760,000 times in a year.

To calculate how many times faster the sparrow's heart beat compared to the human heart, we divide the sparrow's heartbeat in a year by the humans heartbeat in a year. This will be:

= 2,417,760,000 / 1,533,000

= 1577.14 times

A T-shirt printing machine takes 80 minutes to print 1120 shirts. Consider the number of shirts printed per minute. Find the constant of proportionality in this situation. b. Write an equation to represent the relationship. How many shirts are printed in 30 minutes?​

Answers

Answer:

Every minute there are 14 shirts made so there would be 420 shirts made in 30 minutes. Y=14x

Step-by-step explanation:

Divide 1120 by 80 to get 14 then you multiply 14 by 30 to get 420

Then to get an equation you write the number of shirts made per minute and then plug in how many minutes you want.

the volume of a large sphere (of radius R) is twice the volume of a smaller sphere (of radius r). form an equation linking r and R.

Answers

Step-by-step explanation:

radius of large sphere is R,

then volume is (4/3)*pie*R³

and

the radius of small sphere is r,

then volume is (4/3)*pie*r³

condition is,

volume of larger sphere is twice of the volume of smaller sphere.

then, (4/3)*pie*R³=2*(4/3)*pie*r³;

R³= 2r³

R=(2^⅓)*r

what is the solution of −2 < x/4

Answers

Answer:

Inequality Form: x > −8

Interval Notation: (−8, ∞)

Step-by-step explanation:

−2 < x/4

Rewrite so x is on the left side of the i nequality.

x/4 > −2

Multiply both sides of the equation by 4.

x > −2 ⋅ 4

Multiply −2 by 4.

x > −8

The result can be shown in multiple forms.

An Isosceles right triangle has a 90 degree angle and 2
equal acute angles. What is the measure of each of the
acute angles in this triangle?
A. 45 degrees.
B.144 degrees.
C.36 degrees.
D.108 degrees.

Answers

They are 45°.


Explanation:

A triangle equals 180° so if one of the sides is 90° and the other two are equal we know it has to be half of 90 because 90+90 is 180

I’m struggling. Sorry. Any help is appreciated

Answers

Answer:

(8x+13)=(10x-27) being vertically opposite triangles.

Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x

Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x

Answer:

x = 20

Step-by-step explanation:

The 2 angles are vertical and congruent, thus

10x - 27 = 8x + 13 ( subtract 8x from both sides )

2x - 27 = 13 ( add 27 to both sides )

2x = 40 ( divide both sides by 2 )

x = 20

The school that Jeremy goes to is selling tickets to a play. On the first day of ticket sales the school sold 8 senior citizen tickets and 9 child tickets for a total of $188. The school took in $70 on the second day by selling 1 senior citizen ticket and 5 child tickets. What is the price of one senior citizen ticket and one child ticket

Answers

Answer:

x=$10

y=$12

Step-by-step explanation:

Step one:

given

let senior tickets be x

and child be y

8x+9y=188----1

also on the second day

x+5y=70-------2

the system of equation is

8x+9y=188-----1

x+5y=70---------2

x=70-5y, put this in 1

8(70-5y)+9y=188

560-40y+9y=188

-31y=-372

divide by -31

y=-372/-31

y=$12

put y= 12 in x+5y=70---------2

x+5(12)=70---------2

x+60=70

x=$10

You, like all animals as well as plants and fungi, have eukaryotic cells. That means your cells have a nucleus. Inside that nucleus, genetic material (DNA) is coiled into thread-like chromosomes. Organisms with eukaryotic cells are called eukaryotes. Prokaryotic cells, on the other hand, are more simple. They lack specialized, membrane-bound organelles, like mitochondria, and they do not have a nucleus. Their genetic material is usually in a loop that floats in the cytoplasm. That loop is called the nucleoid. Prokaryotic cells are much smaller than eukaryotic cells. All bacteria are unicellular, made of just one cell, and they are prokaryotes. Some bacteria have flagella, tail-like structures on the end that help them to move.How are bacteria cells different from human cells?ABacteria cells do not contain a cytoplasm.BBacteria cells do not contain genetic material.CBacteria cells are much bigger than human cells.DBacteria cells are less complex than human cells.
