What is 65.047 to 1 decimal place?

Anarel [89]

65.0

This is because 4 is not a big enough number to round up, so you must round down. When it is 5 and over, you can round up.

Step-by-step explanation:

YELLOW TRIANGLE:

$\sin(30) = \frac{x}{12} \\ x = 12 \sin(30) = 6$

PURPLE TRIANGLE:

Since one of the angle is 45°, x = BC = 6

To prove:

$\tan(45) = \frac{bc}{x} \\ bc = x \tan(45) = 6 \tan(45) = 6$

PINK TRIANGLE:

$\tan(60) = \frac{bc}{y} \\ y = \frac{bc}{ \tan(60) } \\ = \frac{6}{ \tan(60) } \\ = 2 \sqrt{3}$

PLEASE HELP !!

Soloha48 [4]

Answer:

C. 15

Step-by-step explanation:

Given:

$4x + 2y = 50 \hspace{18mm} (1) \hspace{15mm} x - 3y = 30 \hspace{20mm} (2)$

Dividing Eqn. (1) thorough out by 2, we get $2x + y = 25 \hspace{15mm} (3)$

To solve for $x$ , multiply (3) by 3 and add (2) and (3).

i.e., $6x + 3y - 75 + x - 3y - 30 = 0$

$\implies 7x = 105$

$\implies x = 15$

HELP, DOING A QUIZZ!!!!! ONLY GOT AN HOUR:(

Pavlova-9 [17]

Answer: $P(1$

Step-by-step explanation:

Since we have given that from the table

$P(X=2)=0.07\\\\P(X=3)=0.22\\\\P(X=4)=0.22$

now, we need to calculate,

$P(1$

As we just take the values of from 2 to 4 as 1 and 5 is not included.

So, we get our answer:

$P(1$
