what is the product of (2.8*10^8) and (9.2*10^6)

Answer:

2 will give you the larger value of 17

Step-by-step explanation:

Answer:

Given distance=360 km.

Let the speed of the train be x km/hr.

Speed when increased by 5 km/hr =(x+5) km/hr

Answer:

y = 1.5, x = [tex]1\frac{12}{13}[/tex]

Step-by-step explanation:

The given simultaneous equation system is;

-1 - 2·y = -4...(1)

13·x + 2·y = 28...(2)

By elimination method, we have;

From equation (1);

-1 - 2·y = -4

2·y = 4 - 1 = 3

y = 3/2 = 1.5

y = 1.5

We eliminate 'y' from equation (2) by replacing the value of 'y' with 1.5 as follows;

13·x + 2·y = 28

y = 1.5

∴ 13·x + 2 × 1.5 = 28

13·x = 28 - 3 = 25

x = 25/13 = [tex]1\frac{12}{13}[/tex] = [tex]1.\overline{923076}[/tex]

x = [tex]1\frac{12}{13}[/tex]

Answer:

29 rabbits and 29 chickens.

Step-by-step explanation:

Let there be r rabbits and c chickens.

Then we have the system:

r + c = 58

4r + 2c = 174

Multiplying the first equation by 2:

2r + 2c = 116

Subtracting this equation from the second equation:

2r = 174-116 = 58

r = 29

and c = 58-29 = 29.

Answer:

58 chickens and 116 rabbits

Step-by-step explanation:

Rabbits have 4 legs. Chickens have 2 legs.

4R+2C=174

R+C=58

R=58-C

4x(58-C) + 2C=174

4x58-4C+2C= 174

4x58-2C=174

232-2C=174

232-174= 2C

58=2C (1 chicken)

174-58=116

58 chickens and 116 rabbits

cos25°=BC/AB=8/c

c=8/cos25°

so cos function is helpful here

really a dum.beannie

Answer:

b) cos25

c = 7.248 or 7.2

Step-by-step explanation:

Cosine = [tex]\frac{adjacent}{hypothenuse}[/tex]

Cos 25 = [tex]\frac{8}{c}[/tex]

Cos of 25 is 0.906

0.906 = [tex]\frac{8}{c}[/tex]

Multiply 8 on both sides:

0.906 x 8 = [tex]\frac{8}{c}[/tex] x 8

7.248 = c

Answer:

yes

Step-by-step explanation:

just plug in

2+3 is equal to 5 so that works

4(2)+13(3) is greater than 20 so that also works

Answer:

Yes

Step-by-step explanation:

I can explain more in-depth if you'd like, but basically plug in 2 where x is and plug in 3 where y is. The first equation would turn into 2 + 3 ≤ 5, which is correct, and the second equation would transform to 4(2) + 13(3) > 20. Multiply, then it'll be 8 + 39 > 20, then add 8 and 39 and it'll be 47 > 20, which is true. I hope I explained that well, but yes, (2, 3) is a solution :)

Answer:

- 2t³ + 4t² - t

Step-by-step explanation:

f(t) - g(t)

= 3t³ - 4t + 6t² - (5t³ + 2t² - 3t) ← distribute parenthesis by - 1

= 3t³ - 4t + 6t² - 5t³ - 2t² + 3t ← collect like terms

= - 2t³ + 4t² - t

Answer: The new co-ordinates of A ( 2 ,-6)

Step-by-step explanation:

Type of transformation                                change to co-ordinate point

Vertical translation up 'd' units                  (x,y)→(x , y+d)

Vertical translation down 'd' units             (x,y)→(x , y-d)

Horizontal translation right 'c' units           (x,y)→(x+c , y)

Horizontal translation left 'c' units           (x,y)→(x-c , y)

Reflection over x-axis                               (x,y) →(x , -y)

Reflection over y-axis                               (x,y) →(-x , y)

Given the original vertex A ( -2 ,3)

a) First reflection over x-axis  ( -2 ,3) →(-2 , -3)

b) Vertical translation down '3' units  so it changes (-2 , -3)→(-2 , -3-3)

                        (-2,-3)→(-2 ,-6)

and

c) The Horizontal translation right '4' units

now it changes ( -2 ,-6) → (-2+4,-6)→(2 ,-6)

Final answer:-

The new co-ordinates of A ( 2 ,-6)

Answer:

Side = 0.7 units

Step-by-step explanation:

Area of a square = 0.49 sq. units

Side² = 0.49

side² = [tex]\frac{49}{100}\\\\[/tex]

[tex]side = \sqrt{\frac{49}{100}}=\sqrt{\frac{7*7}{10*10}}\\\\sides=\frac{7}{10}=0.7[/tex]

Answer:

20 times greater

Step-by-step explanation:

Given the following

Population of alaska = 6.5 * 10^(5) people

Population of illinois's = 1.3 * 10^(7)people.

To know the number of times population of Illinois in the population of Alaska, we will take their population ratio;

Ratio = Population of illinois's /Population of alaska

Ratio = 1.3 * 10^(7)/6.5 * 10^(5)

Ratio = 0.2 * 10^7-5

Ratio = 0.2 * 10^2

Ratio = 20

Hence the population of Illinois is 20 times greater than population of alaska

Answer:

-14

Step-by-step explanation:

if n = 1.5, replace all letters labeled "n" with 1.5

5(1.5) - (20 +1.5)

5 x 1.5 = 7.5

(20+1.5) = 21.5

7.5 - 21.5 = -14
