12.13 = 12 13/100....the numbers to the left of the decimal are ur numbers greater then 1....the numbers to the right of the decimal are ur numbers less then 1, ur fractions. Notice the last number (3), it is in the hundredths place...so put it over 100...and then the whole number...giving u 12 13/100

You would keep the 12, and change the .13 into 13/100. 13 is prime, so it can't be simplified, and you would just leave it as 12 13/100 inches

The sum of the reciprocal of two consecutive odd integers is 44/483.Write a rational equation to solve the problem.
Arturiano [62]

Answer:

Step-by-step explanation:

Let consecutive odd integers be (2x + 1) and (2x + 3)

Their reciprocals are \frac{1}{2x + 1 }    and \frac{1}{2x + 3 }

\frac{1}{2x+1}+\frac{1}{2x+3}=\frac{44}{483}\\\\\frac{1*(2x+3)}{(2x+1)(2x+3)}+\frac{1*(2x+1)}{(2x+3)(2x+1)}=\frac{44}{483}\\\\\frac{2x + 3 + 2x +1}{(2x + 1)(2x+3)}=\frac{44}{483}\\\\\frac{4x + 4}{4x^{2}+8x+3}=\frac{44}{483}\\

483*(4x+4) = 44*(4x² + 8x + 3)

483*4x + 483*4 = 44*4x² + 44*8x  + 44*3

1932x + 1932 = 176x² + 352x + 132

176x² + 352x + 132 -1932x - 1932 = 0      

Combine like terms

176x² + 352x - 1932x - 1932 + 132 = 0

176x² - 1580x - 1800 = 0

Divide the equation by 4

44x² - 395x - 450 = 0

x=3 and y=−2

Step-by-step explanation:

Solve8x+5y=14for x:

8x+5y=14

8x+5y+−5y=14+−5y(Add -5y to both sides)

8x=−5y+14

8x8=−5y+148(Divide both sides by 8)

x=−58y+74

Step: Substitute−58y+74forxin−4x−5y=−2:

−4x−5y=−2

−4(−58y+74)−5y=−2

−52y−7=−2(Simplify both sides of the equation)

−52y−7+7=−2+7(Add 7 to both sides)

−52y=5

−52y−52=5−52(Divide both sides by (-5)/2)

y=−2

Step: Substitute−2foryinx=−58y+74:

x=−58y+74

x=−58(−2)+74

x=3(Simplify both sides of the equation)

Answer:

x=3 and y=−2

E im so confused-<br> ( Please explain your answer! )
Drupady [299]

Answer:

  B.  180° about the origin

Step-by-step explanation:

You are given a figure and its image, and asked to determine the angle of rotation. All of the answer choices indicate the center of rotation is the origin.

__

You have two clues that the rotation is 180° about the origin:

  1. The original figure is in the 2nd quadrant, and the image is in the 4th quadrant, directly opposite the origin.
  2. Line ST is directed to the northeast; line S'T' is directed to the southwest, in exactly the opposite direction.

__

To find the angle of rotation, you can look at the angle formed by a point, the center of rotation, and the image of the original point. Here, the angle UOU' is a straight angle, so the angle of rotation about O is 180°--the measure of that angle. (It can be convenient to use points close to the center of rotation, but any corresponding points on preimage and image will do.)

The giant panda population in China is increasing at a rate of 1.5% each year. There are 1864 giant panda in 2014. Write a funct
guajiro [1.7K]

Given:

Giant panda population in 2014 = 1864

The giant panda population in China is increasing at a rate of 1.5% each year.

To find:

The function that models the panda population since 2014.

Solution:

Since population of giant panda is increasing, therefore the function is the exponential growth model.

The general exponential growth model is:

P(t)=P_0(1+r)^t

Where, P_0 is the initial population, r is the growth rate in decimal and t is the time period.

Putting P_0=1864,r=0.015, we get

P(t)=1864(1+0.015)^t

P(t)=1864(1.015)^t

Where, t is the number of years since 2014.

Therefore, the required exponential growth model is P(t)=1864(1.015)^t.
