How many triangles are there in this shape

Answer:

12

Step-by-step explanation:

You are given two lines, the blue one and the one with the letters and are told to find the length of UV (which would just be from point U to point V)

The blue line seems to represent the total length of the black line and the length of VW is already shown. Since the total length is 16 and we alredy know that VW is 4, we'll subtract the two to find the length of UV

Which would be: 16-4=12

Answer:

Answer is 12.

Step-by-step explanation:

If UW is 16, and VW is 4, then just do 16-4 to get 12.

Hope this helps.

Step-by-step explanation:

You multiply the two other sides by itself like 12x12=144 and do that for all the sides that you know then you add up all of the numbers you got from adding like 144 plus 64 equals 208 and then 208 is the hypotenuse.

Answer:

f(1) - 1 = -3

Step-by-step explanation:

Step 1: Find f(1)

f(1) = -3(1) + 1

f(1) = -3 + 1

f(1) = -2

Step 2: Find f(1) - 1

f(1) - 1 = -2 - 1

f(1) - 1 = -3

Answer:

B. 0.3^3 is just 0.3 times itself 3 times. We can right it as 0.3 x 0.3 x 0.3 -> 0.09 x 0.3 -> 0.027

Step-by-step explanation:

Hope this helps :)

0.3^3 is just 0.3 times itself 3 times. Thus, 0.027 option 2 is correct.

If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}[/tex]

We can right it as;

0.3 x 0.3 x 0.3

= 0.09 x 0.3

= 0.027

Therefore, 0.3^3 is just 0.3 times itself 3 times. Thus, 0.027 option 2 is correct.

Answer:

m-4 = 64 degrees.

Step-by-step explanation:

180 - 116 = 64

supplementary angles are when 2 degrees add up to 180

so if one of them is 116 then you subtract that from 180 and get 64

so the other angle would be 64 degrees

Answer:

64 degrees

Step-by-step explanation:

Supplementary angles add up to 180

180-116=64

Answer:

  C. (3x)^2 - (2)^2

Step-by-step explanation:

Each of the two terms is a perfect square, so the factorization is that of the difference of squares. Rewriting the expression to ...

  (3x)^2 - (2)^2

highlights the squares being differenced.

__

We know the factoring of the difference of squares is ...

  a^2 -b^2 = (a -b)(a +b)

so the above-suggested rewrite is useful for identifying 'a' and 'b'.

Answer:

Terminating decimal.

Step-by-step explanation:

We need to find, if a fraction converts into a decimal that eventually stops what do we call it.

If a fraction converts into a decimal that eventually stops is called terminating decimals.

For example : 0.1, 2.45, 3.4657 etc.

If a fraction converts into a decimal that is repeating and do not stops is called non-terminating recurring decimals.

For example : 0.333..., 2.3454545... etc.

If a fraction converts into a decimal that is not repeating and do not stops is called non-terminating, non-recurring decimals.

For example : 0.2345172..., 2.34093795... etc.

Therefore, required answer is terminating decimal.

The answer is

Step-by-step explanation:

- 2x + 4 > - 4x + 8

Add 4x to both sides of the inequality

That's

- 2x + 4x + 4 > - 4x + 4x + 8

2x + 4 > 8

Subtract 4 from both sides

That's

2x + 4 - 4 > 8 - 4

2x > 4

Divide both sides by 2

That's

Answer:

3.6 hours

Step-by-step explanation:

One person can complete a typing project in 6 hours,

Hence, in 1 hour, 1/6 of the project is completed by person A

Another can complete the same project in 9 hours.

Hence, in 1 hour, 1/9 of the project is completed by person B

Let the number of hours of completing the project be represented by 1

Hence,

x/6 + x/9 = 1

We find the L.C.M

9x + 6x/54= 1

15x/54 = 1

Cross Multiply

15x = 54

x = 54/15

x = 3.6 hours.

Therefore, both people can complete the project in 3.6 hours.

Answer:

3.45 acres

Step-by-step explanation:

The area is the average of the the 2 numbers, that is

area of backyard = [tex]\frac{3.4+3.5}{2}[/tex] = [tex]\frac{6.9}{2}[/tex] = 3.45 acres

The area of the backyard will be 3.45 acres.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In other meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

Given that area of backyards is halfway between 3.4 and 3.5 acres

It means an area of backyards will be an average of 3.4 and 3.5 acres

So,

Area of backyards = (3.4 + 3.5)/2 = 3.45 acre.

Hence "The area of the backyard will be 3.45 acres".
