Help, For each equation, use guess-check-and-improve to approximate a
Contact [7]

Answer:

B) 6

Step-by-step explanation:

3(6) + 8 = 26

18 + 8 = 26

26 = 26

I don't know that method they are referring to. Seems pointless.

Typically, you would just set that equation up like:

3n + 8 = 26

    - 8      -8

3n = 18

3n/3 = 18/3

n = 6

What are the values of a and b?
Leona [35]

Answer:

<h2>          A.   \bold{a=\dfrac92\ ,\quad b=\dfrac{15}2}</h2>

Step-by-step explanation:

The segment 6 is dividing the large triangle to similar triangles, so:

\dfrac a6=\dfrac b{10}=\dfrac68

Therefore:

\dfrac a6=\dfrac68\\\\8a=36\\\\a=\dfrac{36}8=\dfrac92            and            \dfrac b{10}=\dfrac68\\\\8b=60\\\\b=\dfrac{60}8=\dfrac{15}2

Find the value of x such that the data set has the given mean.
Klio2033 [76]

therefore, x = 59

Step-by-step explanation:

Here,

Mean (m) = 101

No. of terms (n) = 6

submission x (total) = 102+120+106+111+108+x

= 547 + x

Now, We know;

m = total / n

101 = 547 + x / 6

101 × 6 = 547 + x

606 - 54u = x

Hence , x = 59.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
puteri [66]

To find "s", you can use the Pythagorean theorem(which you can only use for right triangles):

a² + b² = c²               (c is the hypotenuse/the longest side of the triangle)


t = 18  (hypotenuse)

r = 12

s = ?

Plug in the numbers into the equation

a² + b² = c²

(12)² + b² = (18)²

144 + b² = 324        Subtract 144 on both sides

b² = 180           Square root both sides

b = √180  or  13.4
