Answer:

the first one is A, the second one is D.

Step-by-step explanation:

For the perimeter you have to multiply by the original dilation number, and for the area, you have to dilate by 2.5




Hope this helps :D

one angle of a linear pair is 10 more than two thirds the other angle. find the measure if both angles
BigorU [14]

Answer:

One Angle = 110°

Other Angle = 70°

Step-by-step explanation:

A linear pair means that two angles are in a straight line (or, a straight angle).

A straight line is 180 degrees.

THey are supplementary.

We can say one angle is "a" and another one is "b".

<em>One angle is 10 MORE THAN 2/3rds of the other, we can write:</em>

<em>a=\frac{2}{3}b+10</em>

<em />

<em>Also, since they are supplementary (add up to 180), we can write:</em>

<em>a + b = 180</em>

<em />

We can now substitute 1st equation in this one and find b:

a+b=180\\(\frac{2}{3}b+10)+b=180\\\frac{2}{3}b+b=180-10\\\frac{5}{3}b=170\\b=\frac{170}{\frac{5}{3}}\\b=170*\frac{3}{5}\\b=110

Since a + b = 180, we can write:

a + 110 = 180

so,

a = 180 - 110

a = 70

Thus,

One Angle = 110°

Other Angle = 70°

TravelEz sells dollars at a rate of ($1.40)/(1 euro) and buys dollars at a rate of ($1.80)/(1 euro). At the beginning of a trip,
Natalija [7]

Answer:

Sophie will get <u>$56</u> in exchange.

Step-by-step explanation:

Given:

TravelEz sells dollars at a rate of ($1.40)/(1 euro).

And dollars they buy at a rate of ($1.80)/(1 euro).

Sophie exchanged $540 to get 300 euros, at the beginning of trip.

And, she is left with 40 euros at the end of trip.

So exchanges the euros back to dollars.

Now, to find the dollars Sophie will get in exchange.

Let the dollars Sophie will get in exchange be x.

The rate at which TravelEz sells dollars = \frac{\$1.40}{1\ euro}

Number of euros Sophie is left with = 40.

Now, to get the dollars she will get we set proportion:

<em>As, </em>\$1.40<em> is equivalent </em>1\ euro<em>.</em>

<em>So, </em>x<em> is equivalent to </em>40\ euros<em>.</em>

Thus,

\frac{1.40}{1} =\frac{x}{40}

By cross multiplying we get:

56=x

x=\$56.

Therefore, Sophie will get $56 in exchange.

The measures in the table describe the weights of animals that visited a vet on one day, in pounds. Mean Median Mode Mean Absolu
MrMuchimi

Answer: On average, the weight of a pet visiting this vet on this day is about 2.4 pounds away from 12.9 pounds.

If the MAD of weights for another day was 1.5, then that day's weights would be less variable than the weights of pets seen on this day.

Step-by-step explanation:

Given: The measures in the table describe the weights of animals that visited a vet on one day, in pounds.

Mean = 12.9

Median= 12.0

Mode = 12.0

Mean Absolute Deviation = 2.4

We know that the mean absolute deviation (MAD) of a data set is the mean distance between each and every data value and the mean.It tells about the variation in a data set.

Therefore, On average, the weight of a pet visiting this vet on this day is about 2.4 pounds away from 12.9 pounds.

Also, If the MAD of weights for another day was 1.5, and since 1.5< 2.4.

Then that day's weights would be less variable than the weights of pets seen on this day.

Division of two quantities is expressed as the ____ of those two quantities.
andreev551 [17]


Division of two quantities is expressed as the  quotient of those two quantities.

The word quotient is derived from the Latin language. It is from the Latin word "quotiens" which means "how many times." A quotient  is the answer to a divisional problem. A divisional problem describes how many times a number will go into another. The first time that this word was known to have been used in mathematics was around 1400 - 1500 AD in England.

There are two different ways to find the quotient of two numbers.  One of them is through Fractions. The quotient of a fraction is the number obtained when the fraction is simplified. The other way to find a quotient is  by employing the long division method where the quotient  value is positioned above the divisor and dividend.
