Ghella [55]

Answer:

2.22

Step-by-step explanation:

To get 2 2/9 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction. Here are the detailed math steps we use to convert 2 2/9 mixed number to decimal form:

Step 1: Multiply the whole number by the denominator:

2 × 9 = 18

Step 2: Add the product you got in Step 1 to the numerator:

18 + 2 = 20

Step 3: Divide the sum from Step 2 by the denominator:

20 ÷ 9 = 2.222222

That's it! The answer to 2 2/9 in decimal form is displayed below:

2 2/9 ≈ 2.22

if mike invests 2000 in the bank at a simple interest rate of 5.3% for 10 years how much interest will he make?
Tems11 [23]

Answer:

$1060

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5.3%/100 = 0.053 per year,

then, solving our equation

I = 2000 × 0.053 × 10 = 1060

I = $ 1,060.00

The simple interest accumulated

on a principal of $ 2,000.00

at a rate of 5.3% per year

for 10 years is $ 1,060.00.

Which statement correctly compares the two functions shown?
krok68 [10]

Answer:

C.

Step-by-step explanation:

For Function 2

x=1 y=8

x=2 y=11

8=m+b

11=2m+b

11-8=2m-m

m=3

8=3+b

b=5

y=3x+5

Function 1

y=4x+5

Function 2

y=3x+5

....................

Function 1 has the same y-intercept and greater slope than Function 2.

Hello Please Find The Answer To This Question (easy)
irina [24]

The equation of the line that is perpendicular to y = -5/2 x + 1 and passing through (10, 3) will be y = 2/5 x + 1.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The equation of the perpendicular line will be given as

y = mx + c

The given equation is y = -5/2 x + 1.

The slope of the line is -5/2.

Then the product of the slope of the perpendicular lines is a negative one.

-5/2 × m = - 1

m = 2/5

Then the equation will be

y = 2/5 x + c

Then the equation is passing through (10, 3). Then we have

3 = 2/5 × 10 + c

3 = 2 + c

c = 1

Then the equation is y = 2/5 x + 1.

More about the linear system link is given below.

X/2 + 3/2 &lt; 5/2 give solution ​
Nataly [62]

Start with

\dfrac{x}{2}+\dfrac{3}{2}

Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:

x+3

Subtract 3 from both sides:

x
