Mathematics
1 answer:
Mrac [35]3 years ago

Answer:

Part A) The statement is True

Part B) The statement is False

Part C) The statement is True

Part D) The statement is True

part E) The statement is False

Step-by-step explanation:

Part A) we have

1.66..=1 \frac{6}{9}

The statement Is True

Convert the repeating decimal 1.66.. to an equivalent fraction

Let

x=1.66..\\ 10x=16.66..\\ 10x-x=16.66..-1.66..\\ 9x=15\\ x=15/9

Convert to mixed number

15/9=9/9+6/9=1 \frac{6}{9}

therefore

1.66..=1 \frac{6}{9}

Part B) we have

0.6 < 6\%

The statement is false

Because

6\%=6/100=0.06

so

substitute

0.6 < 0.06 -----> is not true

Part C) we have

45\% \leq4.5

The statement is True

Because

45\%=45/100=0.45

substitute

0.45 \leq4.5 ----> is true

Part D) we have

5^{2} \geq 16

The statement is True

Because

5^{2}=25

substitute

25 \geq 16 ----> is true

Part E) we have

9.25 > 9\frac{3}{4}

The statement is false

Because

Convert mixed number to an improper fraction

9\frac{3}{4}=\frac{9*4+3}{4}=\frac{39}{4}

Convert decimal number to an improper fraction

9.25=9\frac{1}{4}=\frac{9*4+1}{4}=\frac{37}{4}

substitute

\frac{37}{4} > \frac{39}{4} -----> is not true

What equation best models this data? (Use y to represent the population in millions, and t to represent the year, assuming that
lapo4ka [179]

Answer:

y = 2.31x + 309.35

Step-by-step explanation:

Whenever you are checking for a best fitting equation you want to check if it has a constant slope.  If it does then the relation is linear and super easy.

So, since the t values are increasing by the same amount you want to see if the y values are  too.  And they are, each population entry is increasing by 2.31, this is the slope.  

Also, keep in mind you can caluclate slope with the equation \frac{y_2-y_1}{x_2-x_1}  here x is replaced by t though.

Now, since we know it's linear and we know the slope we can find the equation with the formula  y - y1 = m(x - x1) where again, x is replaced by t and m is the slope 2.31

I am just going to use the first point.  so x1 = t1 = 0

y - 309.35 = 2.31(x-0)

y = 2.31x + 309.35

Let me know if there was something you didn't understand.

PLEASE HELP!!
sp2606 [1]
Standard form is just putting (in this case) variables in alphabetical order. First we simplify- 2x+4=4y would become 1/2x+1=y. This is already in standard form, as numbers w/o variables come at the end. simplifying the next one is more tricky. first you get a variable/number alone-
9-2x-2y=4x+3
9-2y=6x+3
6-2y=6x
1-1/3y=x
1=x+1/3y
3=x+y
x+y=3
sorry if I was wrong and not of any help, But I do believe this is correct.

Need help figuring this out!
Ulleksa [173]

For this case, we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

where:

b: It's the base

h: It's the height

In this case we have:

b = 21 \ ft\\h = 6 \ ft

Substituting:

A = \frac {21 * 6} {2}\\A = 63 \ ft ^ 2

Answer:

63 \ ft ^ 2
