A) Pine Road and Oak Street form a right angle, so we can extract the relation

\tan30^\circ=\dfrac x{11\sqrt3}\implies\dfrac1{\sqrt3}=\dfrac x{11\sqrt3}\implies x=11

where x is the distance we want to find (bottom side of the rectangle).

Alternatively, we can use the other given angle by solving for x in

\tan60^\circ=\dfrac{11\sqrt3}x

but we'll find the same solution either way.

b) Pine Road and Oak Street form a right triangle, with Main Street as its hypotenuse. We can use the Pythagorean theorem to find how long it is.

(\text{Pine})^2+(\text{Oak})^2=(\text{Main})^2

Let y be the length of Main Street. Then

(11\sqrt3)^2+11^2=x^2\implies x^2=484\implies x=\pm22

but of course the distance has to be positive, so x=22.

Answer:

200 trucks

Step-by-step explanation:

There's about 15 trucks in the 2nd row from the right. It looks to be about 1/2 the size of the rows to the left of it.

So based on that, I can assume, there are about 30 trucks in each of the 5 long rows, and both of the short rows would make up about another 30 trucks total. There are various trucks parked along the perimeter or between rows, so I estimated there would be about 20 of those based on 3 per row.

30 x 5 = 150 +30 = 180 + 20 = 200

It would be 45 cups because each number is multiplied by 5
2 x 5 = 10
3 x 5 = 15
4 x 5 = 20
9 x 5 = 45

What if the value of x? show all work
alina1380 [7]
For this case we can make use of the Pythagorean theorem.
 We have then:
 (root (117)) ^ 2 = x ^ 2 + 6 ^ 2
 Clearing x we have:
 x ^ 2 = (root (117)) ^ 2 - 6 ^ 2
 Rewriting:
 x = root (117-36)
 x = root (81)
 x = 9
 Answer:
 
The value of x is given by:
 
x = 9 cm

Find the value of z. round to the nearest hundredth
Svetradugi [14.3K]

ANSWER

C. 64.29

EXPLANATION

The bigger right triangle is similar to the smaller right triangle, therefore

\frac{30}{14}  =  \frac{z}{30}

Multiply both sides by 30;

30 \times  \frac{30}{14}  =  \frac{z}{30}  \times 30

Simplify

z =  \frac{900}{14}

z = 64.28571429

We correct to the nearest hundredthth to obtain,

z = 64.29

The correct choice is C.
