Answer:

[A] 18

Explanation:

[I'm assuming you want us to find the measure of ∠ABC]

∠ABC is a right angle, meaning ∠ABD and ∠DBC added together must equal 90°

2x° + 3x° = 90

2x + 3x = 5x

5x = 90

5x / 5 = 90 / 5

x = 18

Answer:

Step-by-step explanation:

1l ........8.5 miles

x l .......6 miles

-----------------------

x=6*1/8.5

x=0.70 l

2*0.7=1.4 l petrol/day ( to work and come back home)

5*1.4=7 l/week ( 5 days works in a week)

7*1.26=8.82 L /week

8.82>8.5

The petrol costs more

Find the radius of a circle that has an area of 6.76 cm². Use it for pi.

Inessa05 [86]

Answer:

<h2>radius = 1.47 cm</h2>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius

From the question

Area = 6.76 cm²

To find the radius substitute the value of the area into the above formula and solve for the radius

That's

$6.76 = \pi \: {r}^{2}$

Divide both sides by π

We have

${r}^{2} = \frac{6.76}{\pi} \\ r = \sqrt{ \frac{6.76}{\pi} }$

r = 1.46689291

We have the final answer as

radius = 1.47 cm

Hope this helps you

$\bf \begin{cases}

g(x)=\cfrac{-x}{x-3}
\end{cases}\qquad f(x)+g(x)\implies \cfrac{x}{x-9}+\cfrac{-x}{x-3}$

get their LCD, like you'd with any other fractions, and add them up
