Answer:

C: Irrational

Explanation:

the reason i chose C because when you add a rational and irrational number together you still get a repeating number which is irrational.

For Example: Take a rational number 5 and Pi

if you ad those together 5+3.1415... you still get a repeating decimal, and repeating decimals are also irrational numbers.

Hope this helps :D

Answer:

Step-by-step explanation:

2081.25 ; 2312.50 ; 2543.75 ; ..... 7500

a= 2081.25

d = 231.25

$t_{n}= 7500$

$a + (n-1)d = t_{n}$

2081.25 + (n-1) * 231.25 = 7500

(n -1) *231.25 = 7500 - 2081.25

231.25n - 231.25 = 5418.75

231.25n = 5418.75 + 231.25

231.25n = 5650

n = 5650/231.25 = 565000/23125

n = 904/37

n = 24 years 157 days

Convert 120 kilometers per hour into miles per hour using dimensional analysis

musickatia [10]

Answer:

74.56 miles / h

Step-by-step explanation:

1 mile = 1.609 km

Using the dimensional analysis you multiply the number you want to convert by 1 (using a fraction with the needed units)

Since 1 mile = 1.609 km then:

$1= \frac{1 mile}{1.609 km}$

Now to convert 120 kilometers per hour to miles per hour :

$120 \frac{km}{h} * \frac{1 mile}{1.609 km} = \frac{120}{1.609}\frac{miles}{h} = 74.56 \frac{miles}{h}$
