Answer:

1.6, 1.64, 16.099, 16.4

Step-by-step explanation:

Add a 0.

1.60, 1.64, 16.099, 16.40

The ones are of lesser value because they only have one whole number, and the 16.099 is less than 16.40 because it has that 0 in front of the nines.

Step-by-step explanation:

Answer:

m=-7/2

Step-by-step explanation:

 (5 • (m + 2) -  m) -  (2m + 3)  = 0

 2m + 7  = 0

3.1      Solve  :    2m+7 = 0

Subtract  7  from both sides of the equation :

                     2m = -7

Divide both sides of the equation by 2:

                    m = -7/2 = -3.500

Answer

5(m+2)-m=2m+3

5m+10-m=2m+3

5m-2m-m=-10+3

3m-m=-10+3

2m=-7

m= -7/2

m= -3.5

Answer:

No possible answer (unless the equal sign was supposed to be a plus sign, then see answer below)

Step-by-step explanation:

we can simplify the expression like such:

24 + 2x = 2x = 24

As you will notice 2x + 24 cannot equal 2x, or 24.

If the equals sign was a typo and was meant to be a plus sign then the answer is all real numbers.

2(12 + x) can be broken down to (2*12) + (2*x) which equals 2x + 24.

Then this equals the other side of the equation meaning that it doesn't matter what x equals the equation is always equal.

Answer:

x = - 13

Step-by-step explanation:

- 0.4(x + 3) = 4 ( divide both sides by - 0.4 )

x + 3 = - 10 ( subtract 3 from both sides )

x = - 13

Answer:

h = 16°

Step-by-step explanation:

The total angle of a straight line = 180°.

So we can say that 151° + x = 180°

180° - 151° = x

x = 29°

total angles of a triangle = 180°

∴ 118 + 29 + 2h + 1 = 180

⇒ 148° + 2h = 180°

⇒ 2h = 180° - 148°

⇒2h = 32°

⇒h = 32° ÷ 2

⇒ h = 16°

Answer: The area of the shaded region is 30 cm^2

Step-by-step explanation:

First, we recall the area for a rectangle and a triangle.

-Area for rectangle: A = L x W

-Area for triangle: A = 1/2 x b*h

Next, I find the area of the total region.

-12 cm x 4 cm = 48 cm^2

Then, I find the area for the non-shaded region (or the white triangle)

- A= 1/2 x 9*4

- A= 1/2 x 36

- A = 18 cm^2

Finally, I subtract the total area of the whole region from the non-shaded region ( or again white triangle)

- 48 minus 18 = 30 cm ^2

Answer:

1.44 meters squared

Step-by-step explanation:

area = h · b

1.60 * 0.75 = 1.2

1.2 * 1.2 ( to find area in m square ) = 1.44

Answer:

Step-by-step explanation:

It is because since Cody's age is x years, 9 times x minus 3 is Cruz's age.

Answer:

Step-by-step explanation:

In similar triangles, corresponding sides are in same ratio.

AD = 14 + 8 = 22

[tex]\dfrac{AD}{AB}=\dfrac{DE}{BC}=\dfrac{AE}{AC}\\[/tex]

[tex]\dfrac{AD}{AB}=\dfrac{DE}{BC}\\\\\\\dfrac{22}{14}=\dfrac{DE}{10}\\\\\\\dfrac{22}{14}*10=DE\\\\\\DE = 15.71[/tex]

[tex]\cfrac{\stackrel{Ann}{120}}{\underset{Betty}{b}}~~ = ~~\stackrel{ratio}{\cfrac{2}{3}}\implies 360=2b\implies \cfrac{360}{2}=b\implies 180=b[/tex]

Answer:

Answer:

67.5°

Step-by-step explanation:

3x+X+90=360°(circle angle)

4x=360-90

4x=270

X=270/4

X=67.5°

Answer:

150% is the right answer

Answer:

3.2%

Step-by-step explanation:

You want to find the area of the hole and the area of the board. The area of the board is 21x42 which is 882 inches squared. The circular hole has a radius of 3 inches so [tex]\pi[/tex]3² which is 9[tex]\pi[/tex].

Now put in calculator [tex]\frac{9\pi }{882}[/tex] which is pi over 98 which simplifies to 0.032.
