The High Roller, a giant ferris wheel in Las Vagas, casts a 242-foot shadow. A 6’3” tall man standing nearby casts a 2 3/4-foot
Ira Lisetskai [31]

Answer:

550ft

Step-by-step explanation:

Simple napkin math, so you know what both shadows are you need to find how tall the High Roller is we will use X for this.

\frac{242ft}{6'3"}  x \frac{x}{2'9"}

Im not 100% I set it up right but essentially 242 divided by 2'9" and that equals 88

Take 88 and multiply that by 6'3" and you get your Height for the High Roller

What I did their was I scaled the humans height to that of the High Roller dividing it gives you a number you can use to scale the height of that human to how it should scale to the High Roller, which is why I took 88 and multiplied it by the human's height.

Hope this helped :)

HELP Plssss..... The m
hammer [34]

Answer:

Step-by-step explanation:

Hey there!!!

According to the question,

Angle P is three less than twice less of an angle Q.

Then, let angle Q be x then angle P is 2x-3.

Now, it has also given that they are supplementary angle.

We know that the sum of supplementary angle is 180°.

Therefore, x+ 2x - 3°=180°.

Or, 3x = 180°-3°

Or, x = 177°/3

Therefore the measure of angle Q is 59° and P is 2×59°-3°= 121°.

Hope it helps....

Step-by-step explanation:

<u><em>The correct question is</em></u>

Jackson bought 5 ounces of raisins for $4 dollars.

To find out the unit rate divide the total cost by the total weight

so

\frac{4}{5} =\$0.8\ per\ ounce

therefore

The raisins cost $0.8 per ounce

Part b) How many ounces of raisins can be bought for $1?

we know that

The raisins cost $0.8 per ounce

using proportion

Find out how many ounces of raisins can be bought for $1

Let

x -----> the ounces of raisins

\frac{1}{0.8}=\frac{x}{1}\\\\x= 1.25\ ounces
