expression for "12 times 1."  -> 12*1

Step-by-step explanation:

x+2x+6x=180

9x=180

x=20°

m<A = 20°

Answer:

Y = x+3

Step-by-step explanation:

You want to start by figuring out how to get Y alone.

So to get it alone so you add +3 on both sides

Y - 3 = x

+3. +3

Positive 3 and Negative 3 cancel out making it zero.

Visual: 3 - 3 = 0

Since you cant take or add anything from x you leave it as + 3 so the answer should be.

Y = x + 3

I hope I could help :)

Step-by-step explanation:

Height of tower - 80m

Distance between foot of tower and boat 1 = x

Distance between boat 1 and boat 2 =y

Tan 45 = 1 = 80/x

x = 80

Tan 30 = 1 / root 3 = 80 / 80 + y

y = 80 root 3 + 80

A

Step-by-step explanation:

This graph represents the inequality x < 2. you may be confused as to why the answer is not x ≤ 2, but the circle at the start of the line is not shaded in. This tells us that an answer to this inequality cannot be x

Answer:

(x - 4)(x - 3)

Answer:

44 inches and 24 inches

Step-by-step explanation:

Let [tex]l,b[/tex] denotes length and breadth of a rectangle.

[tex]lb=1056[/tex]

A square of 3 inches is cut from each corner, and an open box is made by turning up the ends and sides.

New length [tex]=l-6[/tex] inches

New breadth [tex]=b-6[/tex] inches

Height of box [tex]=3[/tex] inches

Volume of box = length × breadth × height

[tex](l-6)(b-6)3=2052[/tex]

[tex]lb-6l-6b+36=684\\6(l+b)=408\\l+b=68\\b=68-l[/tex]

Put [tex]b=68-l[/tex] in [tex]lb=1056[/tex]

[tex]l(68-l)=1056\\l^2-68l+1056=0\\l^2-44l-24l+1056=0\\l(l-44)-24(l-44)=0\\(l-24)(l-44)=0\\l=24,44[/tex]

At [tex]l=24,b=\frac{1056}{24}=44[/tex] inches

At [tex]l=44,b=\frac{1056}{44}=24[/tex] inches

Answer:

50%

Step-by-step explanation:

To solve this you would do 1350/2700 which is 50%

Answer:

l=13 ft

w=6.5 ft

Step-by-step explanation:

a rectangular garden would have 4 sides

two of the sides are x feet long

and the other two sides are 2x feet long

therefore

x+x+2x+2x=39

which is the same as saying

6x=39

divide both sides by 6 to get

x=6.5

so the width is 6.5 feet and the length is twice that or 13 feet

Answer:

30% of the people surveyed in the mall go to movies at least once in a month

Step-by-step explanation:

A descriptive statistic would refer to a summary where it explain in quantitative way from the information collected also it it is used to analyze it. The parameter and descriptive statistics would be the percentage for the surveyed people that goes to the mall for watching out the movies at least for one time in a month

Here 30% come from

= 36 ÷ 120

= 30%

Answer:

no, 71.106 is greater

2. -x+4+3x+2=2x+6

3. -x-2-4x-3=-5x-5

4.-36-24=-60

5.  9+10-6-6=7

Answer:

Step-by-step explanation:

x is the third side

x² + 32² = 68²

x² = 68² - 32² = 3600

x = √3600 = 60

Answer:

22 and 2/3

Step-by-step explanation:

Height = √(90^2-63^2) = √4131 ≈ 64 ft

true

oops, i read it wrong LOL, it's true. .65 is less than .75

Answer:

1. P = [tex]\frac{I}{rt}[/tex]

2.  y = [tex]\frac{6 - 3x}{11}[/tex] or [tex]\frac{-3x +6}{11}[/tex]         (depending on how you want the equation arranged)

3. c = [tex]\frac{a-bd}{b}[/tex]

4 t = [tex]\frac{A - p }{pr}[/tex]

Step-by-step explanation:

1. I =Prt for P:

I = Prt                           divide both sides by rt to isolate P

P = [tex]\frac{I}{rt}[/tex]

2. 3x + 11y = 6 for y

   3x + 11y = 6                  subtract 3x from both sides

   11y = 6 - 3x                   divide both sides by 11

   y = [tex]\frac{6 - 3x}{11}[/tex] or [tex]\frac{-3x +6}{11}[/tex]         depending on how you want the equation arranged

3. a = b(c + d) for c

   a = b(c + d)                distribute b to (c+d)

   a = bc + bd                subtract bd from both sides

   a - bd = bc                 divide both sides by b

   c = [tex]\frac{a-bd}{b}[/tex]

4. A = p + prt for t

   A = p + prt                   subtract p from both sides

   A - p = prt                    divide both sides by pr

   t = [tex]\frac{A - p }{pr}[/tex]

Answer:

D) 31

Step-by-step explanation:

2x-7+2x+63=180

4x+56=180

4x=180-56

4x=124

x=124/4

x=31

Answer:

(d) x = 31

Step-by-step explanation:

(2x)° + (2x - 7)° + 63° = 180°

4x - 7 + 63 = 180

4x = 180 - 56

4x = 124

x = 31
