the answer is 78 kilometers.

1 cm=15 kilometers

so, 6 cm is equal to 90 kilometers.

0.8 millimetres is approximately 12 kilometers.

90 kilometers minus 78 kilometers is equal to 12.

2) AB = BC. Congruent sides of isosceles triangle

3) AE Cong. DC. Given

4) AE = DC. Definition of congruency

5) ED Cong. ED. Reflexive property of equality

6) AE + ED = DC + ED Addition property of equality

7) AE + ED = AD, DC + ED = CD Addition property of equality

8) AD = ED, Substitution property of equality

9) AD Cong. ED Definition of congruency

Please solve with full steps (only question 6)

Answer:

$\large \boxed{\sf \ \ k=1 \ \ }$

Step-by-step explanation:

Hello,

First of all, let's notice that even if we do not know the zeros of P(x) we can say that

$(1) \ \alpha + \beta =\dfrac{5}{6} \\ \\ (2) \ \alpha * \beta =\dfrac{k}{6}$

<u>But, why !?</u>

As they are the zeros of P(x), we can write:

$P(x)=6(x^2-\boxed{\dfrac{5}{6}}x+\boxed{\dfrac{k}{6}})=6(x-\alpha)(x-\beta)=6(x^2-\boxed{(\alpha +\beta)}x+ \boxed{\alpha *\beta} )$

And then we can identify the coefficients of the like terms to find the equations (1) and (2).

Now, we have <u>one more equation</u> which is:

$(3) \ \alpha -\beta =\dfrac{1}{6}$

(1)+(3) gives:

$\alpha + \beta +\alpha -\beta =\dfrac{5}{6}+\dfrac{1}{6}=\dfrac{6}{6}=1 \\ \\ 2\alpha =1 \ \text{ divide by 2 } \\ \\ \alpha =\dfrac{1}{2}$

And we replace in (3) to get the value of the second zero.

$\beta = \dfrac{1}{2}-\dfrac{1}{6}=\dfrac{3-1}{6}=\dfrac{2}{6}=\dfrac{1}{3}$

And, finally, from (2), it comes:

$k=6*\alpha *\beta =6*\dfrac{1}{2}*\dfrac{1}{3}=\dfrac{6}{6}=1$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

The ratio of the length to the width of a map is 8 to 5. The map is exactly 32 inches in length. What is the width of the map? A

docker41 [41]

Ratio of length to width of a map = 8:5

Length of the map = 32 inches
Let the width of the map = x inches

So,

Length : Width = 8 : 5
32 : x= 8: 5

x = 5/8 * 32

x = 20 inches

So, the width of the map is 20 inches
