Alexxx [7]

$f(1)=3\\\\f(n)=[f(n-1)]\\\\f(2)=[f(2-1)]=[f(1)]=[3]=3\\\\f(3)=[f(3-1)]=[f(2)]=[3]=3\\\\f(4)=[f(4-1)]=[f(3)]=[3]=3\\\\f(5)=[f(5-1)]=[f(4)]=[3]=3$

Given that ABCD is a rhombus, what is the value of x?

stealth61 [152]

Answer:

Diagonals of a rhombus intersect at right angles

Therefore, $\angle AOD=90$

$Now,in\: \bigtriangleup AOD$

$\angle OAD+\angle AOD+\angle ADO=180$

$x+90+3x+12=180$ $\leftarrow [combing \: like\: terms]$

$4x+102=180\\-102 \: -102$ $\leftarrow [subtracting \:102 ]$

$\frac{4x}{4} =\frac{78}{4} \leftarrow [dividing \: by\: 4]$

$x=19.5$ $\Longleftarrow$

Pls help and show work so I can understand

Since there is no x it’s simply moving down 4. There is no movement left or right (x) just simply down for -4.

Leo reads 14 pages in 1/2 hour. What is the unit rate for pages per hour? For hours per page?

SVEN [57.7K]

Answer:

1:28 | 1:1/28

Step-by-step explanation:

We can show the first two numbers as a ratio:

14:1/2

But we want that second number to be 1 so we can multiply by 1:

28:1 <------ Pages per hour

But now we need the left to be 1, so we divide by 28:

1/28:1

Then flip:

1:1/28
