X/3 = 10 question 24 options: 10 3 30 7

Answers

x ÷ 3 = 10

what you want to do is isolate for x by multiplying both sides by 3

10 × 3 = 30

So x = 30
x/3=10 

x=10*3 

x=30

1+4=5
2+5=12
3+6=21
8+11=

Answers

There's a pattern
You see, like in this problem:
2 + 5 = 12
They did 5 times 2 = 10, plus da 2 in da problem = 12.
Same with 3 + 6 = 21, 6 times 3 = 18, 18 plus da 3 given in da problem = 21.
Just like 1 + 4 = 5, 4 times 1 = 4, plus da 1 in da problem = 5.
SO,
with that strategy, 8 +11 = 96, because 8 times 11 = 88, plus da 8 given in da problem = 96.
I hope I helped! =D

Solve 2cos^2x+3cosx-2=0

Answers

\bf 2cos^2(x)+3cos(x)-2=0\impliedby \textit{so, notice is just a quadratic} \n\n\n\ [2cos(x)~~-~~1][cos(x)~~+~~2]=0\n\n -------------------------------\n\n 2cos(x)-1=0\implies 2cos(x)=1\implies cos(x)=\cfrac{1}{2} \n\n\n \measuredangle x=cos^(-1)\left( (1)/(2) \right)\implies \measuredangle x= \begin{cases} (\pi )/(3)\n\n (5\pi )/(3) \end{cases}\n\n -------------------------------\n\n cos(x)+2=0\implies cos(x)=-2

now, for the second case, recall that the cosine is always a value between -1 and 1, so a -2 is just a way to say, such angle doesn't exist.

A circular patio has a radius of 18 feet.What is the longest distance across the patio?
A.
9 ft
B.
18 ft
C.
36 ft
D.
54 ft

Answers

The longest distance of a circle is its circumference.

Circumference = π d
d = diameter is twice the radius

C = 3.14 * 2 * 18ft
C = 3.14 * 36 ft
C = 113.04 ft

However, with the choices we only need to get the diameter as the longest distance from one end of the circular patio to the other.

d = 2 r
d = 2 * 18ft
d = 36 ft.  CHOICE C.
We have some clues here. 

'longest distance' could mean Diameter. 

r*2= d
radius = 18 feet
18*2 = 36

d = 36

The answer would be: 36 ft
