Choose the right answer. A series of light brown lines drawn at intervals of 50 feet to designate their respective heights above

Natali [406]

Answer:

Contour lines

Step-by-step explanation:

A series of light brown lines drawn at intervals of 50 feet to designate their respective heights above sea level are called CONTOUR lines, or just contour.

A contour line (also called isoline) is a line that indicates points at the same elevation on the map, showing you a representation of the terrain's elevation (hills, mountains, canyons and so on). You will find those lines on specialized maps, like topographic maps, which are different than road maps.

Myra asked Annabelle to buy her some perfume while she was in France. Annabelle paid 200 euros for it. Myra wants to pay Annabel

serious [3.7K]

Answer:

286

Step-by-step explanation:

Given : Myra asked Annabelle to buy her some perfume while she was in France. Annabelle paid 200 euros for it. Myra wants to pay Annabelle back in U.S. dollars.

To Find: If the foreign exchange rate between the U.S. dollar and the euro is 1:0.7, how much should Myra pay Annabelle?

Solution:

Since Annabelle paid 200 euros

And Myra wants to pay Annabelle back in U.S. dollars.

Let Myra paid amount to Annabelle in U.S. dollar be x

We are also given that the U.S. dollar and the euro is 1:0.7

⇒ $\frac{1}{0.7}=\frac{x}{200}$

⇒ $\frac{1*200}{0.7}=x$

⇒ $\frac{200}{0.7}=x$

⇒ $285.7=x$

⇒285.7≈286

Thus Myra should pay $286 to Annabelle

Pleaseeee answer quick WILLL GIVE BRAINLIEST!!!!!! Given the expression: 5x10 − 80x2 Part A: Rewrite the expression by factoring

sladkih [1.3K]

Answer:

$5\,x^{10}-80\,x^2=5\,x^2\,(x^4+4)(x^2-2)(x^2+2)$

Step-by-step explanation:

First, extract the greatest common factor of the numerical as well as the variable parts:

the GCF of 5 and 80 is "5", and the GCF between $x^{10}$ and $x^2$ is $x^2$ , then:

$5\,x^{10}-80\,x^2=5\,x^2\,(x^8-16)$

Now, we can re-write the binomial in parenthesis as a difference o squares to be able to factor out even further:

$x^8-16=(x^4)^2-4^2=(x^4-4)(x^4+4)$

we now repeat the process for the binomial difference:

$(x^4-4)=((x^2)^2-2^2)=(x^2-2)(x^2+2)$

So finally the complete factorization is:

$5\,x^{10}-80\,x^2=5\,x^2\,(x^4+4)(x^2-2)(x^2+2)$

PLEASE HELP!!! ASAP The function graphed approximates the height of a rock, in meters, x seconds after it falls from a cliff

nasty-shy [4]

The vertical numbers are the distance and the horizontal numbers are the time in seconds.

Look at where the line is located at the number 20.

It si between the 2 and the 3 on the horizontal line, but you can see it is closer to the 2 than it is the 3, so the time would be 2.2s
