In a certain country, the life expectancy of a woman born in 1995 was 80.2 years. Between 1995 and 2005, the life expectancy increased 0.4 year every 5 years.

Answers

Answer 1

Answer:

The Equation of life expectancy is x- 0.4(2) = 80.2.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

The life expectancy of a woman born in 1995 was 80.2 years.

The life expectancy increased 0.4 year every 5 years.

So, from 1995 to 2005 there are two times the life expectancy increase.

let the lifeexpectancy by x.

Thus, the equation is

x- 0.4(2) = 80.2

Answer 2

Answer:

Answer:

a. L - 0.4(2)= 80.2 or L - 80.2 = 0.4(2) or 80.2 + 0.4(2) = L

b. No; The equations must be equivalent. They may look different, but all equations can be rewritten as L= 80.2 + 0.4(2).

2/3x+4=2x
Is it always, sometimes, or never true?

Answers

Presuming the first element of the equation is (2/3)x and not 2/(3x) then 4=(4/3)x ... 1=x/3 ... X=3 So x=3 is a solution

Final answer:

The equation 2/3x + 4 = 2x is sometimes true, specifically when x = 3. For any other values of x, it is not true.

Explanation:

The equation you've provided is 2/3x + 4 = 2x. To determine whether this is always, sometimes, or never true, we can solve for x. Start by subtracting 2/3x from both sides of the equation to isolate the term with 'x' on one side. This yields 4 = 2x - 2/3x, or 4 = 4/3x. If we divide both sides by 4/3 (or multiply by the reciprocal 3/4) to further isolate x, we get x = 3. Thus, the equation is true for x = 3 and not true for any other value of x, so it's not always true but sometimes true.

1 / 2 = ( 1 * 8 ) / ( 2 * 8 ) = 8 / 16 ;
9 / 16 + 8 / 16 = ( 9 + 8 ) / 16 = 17 / 16 ;

9 /16 + 1/2 =?
9 /16 = 0. 5625
1/2 = 0.5

What is the intersection of plane STXW and SVUT?A. SV
B. ST
C. YZ
D. TX

Answers

B. ST is the intersection of plane STXW and SVUT.

Answer: B. ST.

Step-by-step explanation: The intersection of two planes, if exists, is a straight line. Since the planes STXW and SVUT have S and T as common points and we can always draw a straight line given any two points in a plane, so ST is the line joining the points S and T, and hence, it is the intersection of the two given planes.

Thus, the correct option is B. ST.

Jill typed 84 words in 2 minutes . assuming that she types at a constant rate , How many words does she type in 1 minute , 3 minutes and 9 minutes ?

Answers

At the rate of 84 words per 2 minutes, which translates to 42 words per one minute.

So in one minute she types 42*1=42 words
In 3 minutes she types 42*3=126 words
In 9 minutes she types 42*9=378 words

If she typed 84 words in two minutes, and you must find how many words she types at 1 minutes, 3 minutes, and 9 minutes is she was consistent in her speed, all you have to do is find the WPM (words per minute), and then multiply. Since we start with her WPTM (words per two minutes), we simply divide that by two.
84/2=42
So, our WPM rate is 42.
So, she types 42 words in one minute.
42*3=126
She types 126 words in three minutes.
42*9=378
She types 378 words in nine minutes.
