Answer:

$1 \cdot 10^7 +2 \cdot 10^6+ 4 \cdot 10^5+ 3 \cdot 10^4$

Step-by-step explanation:

write 12,430,000 in expanded form using exponents

First we write the expanded form of each digit

1 is in ten millions place , 1 times 10,000,000

2 is in millions place , 2 times 1,000,000

4 is in hundred thousands place , 4 times 100,000

3 is in ten thousands place , 3 times 10,000

Now we write it in expanded form

$1 \cdot 10,000,000 +2 \cdot 1,000,000 + 4 \cdot 100,000+ 3 \cdot 10,000$

$1 \cdot 10^7 +2 \cdot 10^6+ 4 \cdot 10^5+ 3 \cdot 10^4$

The blue whale is the largest animal living on the earth. The average blue whale measures 100 feet long (30 meters) and weighs 3

mamaluj [8]

The average blue whale measures 100 feet(30 meters) long and weighs 300,000 pounds(136,000 kilograms).

A whale’s head is $\frac{1}{3}$ of the length of its body. So, the length of a whale's head $=(\frac{1}{3}*100)feet = 33.33 feet$ or $(\frac{1}{3}*30)meter= 10 meter$

A new baby whale is $\frac{1}{4}$ length of a grown whale. So, the length of a new baby whale $=(\frac{1}{4}*100)feet = 25 feet$ or $(\frac{1}{4}*30)meter = 7.5 meter$

The average man is $\frac{1}{17}$ the length of a blue whale. So, the height of the average man $=(\frac{1}{17}*100)feet = 5.88 feet$ or $(\frac{1}{17}*30)meter =1.76 meter$

The average man is $\frac{1}{1818}$ the weight of a blue whale. So, the average man weighs $= (\frac{1}{1818}*300000)pounds= 165.02 pounds$ or $= (\frac{1}{1818}*136000)kilograms= 74.81 kilograms$

A human baby measures $\frac{1}{4}$ of the length of an adult. So, the height of the average human baby $= (\frac{1}{4}*5.88)feet = 1.47 feet$ or $= (\frac{1}{4}*1.76)meter = 0.44 meter$

Rumor of the cancellation of final exams began to spread one day on a college campus with a population of 80 thousand students.S

Nikolay [14]

Answer:

P(t) is directly proportional to N and N'.

Where P is the increase in numbers of students who have heard the exam's cancellation rumor at any time t;

N is numbers of students who have heard the rumor of the exam's cancellation;

N' is numbers of students who have not heard the rumor of the exam's cancellation;

N' = (80 - N). Since the total number of students is 80;

K is the constant of the proportionality.

K is calculated to be 9/700

Therefore,

P(t) = KNN'

P(t) = (9/700) x N x (80 - N)

Step-by-step explanation:

The total number of students is 80. For N, N' = 80 - N.

Initially, 1 thousand people heard the rumor.

Within/after a day, the increased in number of students who have heard the rumor is P = 10 - 1 = 9

P = 9 = K x 10x (80-10)

9 = K x 10 x 70 = 700K.

Divide both sides by 700,

9/700 = (700/700)K

K = 9/700

Subtitle K into the equation P(t) = KNN'

P(t) = (9/700) x N x N'

P(t) = (9/700) x N x (80 - N), where N' = 80 - N

the members of the gardening group plan to build a walkway through the garden as formed by the IHOP potenuse of each of the four

aliya0001 [1]

Answer:

50.24 yards

Step-by-step explanation:

We will use the pythagorean theorem to find hypotenuse of each of the 4 triangles.

Pythagorean Theorem is $Hypotenuse^2=OneLeg^2+AnotherLeg^2$

For Spinach area, two of the legs are 8 and 6. Solving for hypotenuse:

$hyp^2=6^2+8^2\\hyp^2=100\\hyp=10$

For watermelon area, two of the legs are 12 and 8. Solving for hypotenuse:

$hyp^2=12^2+8^2\\hyp^2=208\\hyp=\sqrt{208}$

in red peppers area, the hypotenuse is already given as 15. But we need to find one leg since that will be the leg of the triangle in tomatoes area. Hypotenuse is 15 and one leg is 12, so the other leg is:

$15^2=12^2+eg^2\\15^2-12^2=leg^2\\leg=9$

So, in tomatoes area, we have one leg 9 and another leg 6. Solving for hypotenuse:

$hyp^2=9^2+6^2\\hyp^2=117\\hyp=\sqrt{117}$

Adding all the four hypotenuses, we get the length of the walkway:

Length of Walkway = $10+\sqrt{208} +15+\sqrt{117}\\ =50.24$ yards

You mix soda water, fruit punch concentrate, and ginger ale in the ratio of 1 : 2 : 5 to make fruit punch. How many pints of eac

EastWind [94]

So the ratio is 1 to 2 to 5
so basically 1 unit of soda water to 2 units of fruit punch to 5 units of ginger ale

total is 1+2+5=8 units

so 4 gallons=8 units
divide by 8
1/2 gallon=1 unit

soda water=1 unit=1/2 gallon
fruit punch=2 unit=1/2 times 2=1 gallon
ginger ale=5 unit=5 times 1/2=5/2=2 and 1/2 gallon

soda water=1/2 gallon
fruit punch concentrate=1 gallon
ginger ale=5/2 gallon or 2 and 1/2 gallon
