Debora [2.8K]

Answer:

The fraction of the students that walk in in Marla's school is equal to $\frac{2}{9}$

Step-by-step explanation:

Let

x------> the total students in Marla's school

we know that

The number of students that not ride the bus is equal to

$\frac{6}{15}x\ students$

The number of students that walk to the school is equal to

$\frac{6}{15}x*\frac{5}{9}=\frac{2}{9}x\ students$

therefore

The fraction of the students that walk in in Marla's school is equal to $\frac{2}{9}$

A tourist looks out from the observation deck of the Space Needle in Seattle. The deck is at a height of 520 ft. She sees her fr

WARRIOR [948]

Answer:

Last option 527.7 ft

Step-by-step explanation:

From the diagram attached we can see the angle of depression is 80.2 which is equal to ∠ACB (alternate angles)

Height of the deck AB = 520 ft. and we have to calculate the distance H between the tourist and her friend.

Sin ∠ACB = $\frac{AB}{AC}$

Now we apply sin rule sin 80.2 = $\frac{520}{H}$

$.9854=\frac{520}{H}$

$H = \frac{520}{.9854} = 570 ft$

So the tourist and her friend are 527.7 ft apart.

Kamila [148]

Answer:

4n-7

Step-by-step explanation:

First, you know that Sam's equation is 4n, since it is 4 times Declan's value n. Next, you take Sam's equation and subtract 7 from that value, since Amaya has 7 fewer cards than Sam. The final equation will be 4n-7.
