Each morning Rin rides 1.5 miles to school and then rides home in the afternoon. Later in the evening, she rides to the park and
zimovet [89]
Although you didn’t list any equations, here is the correct one:

15 + 5x = 25

1.5 twice a day makes it so it’s 3 miles total. Thus, you need to multiply that by 5 to get the total amount in one week.

x will solve for each evening per day.

Hope this helps!

A figure is dilated by a scale factor of 2.5. If the origin is the center of
katen-ka-za [31]

Answer:

C.

Step-by-step explanation:

So, if the new image coordinates are (7,9) and it is dilated from the origin there is a rule. If it is dilated from the origin you would multiply the pre-image coordinates by the scale factor so, (kx,ky) where k is the scale factor. In this case, we would divide by 2.5 so 7 divided by 2.5 is 2.8 and 9 divided by 2.5 is 3.6. The correct answer would be C. (2.8,3.6).

Given △ABC. m∠A>m∠B>m∠C. Perimeter=30. Which side of △ABC may have length 7?
lisabon 2012 [21]

<u>Solution-</u>

As given in △ABC,

m\angle A>m\angle B>m\angle C

As from the properties of trigonometry we know that, the greater the angle is, the greater is the value of its sine. i.e

\sin A>\sin B>\sin C

According to the sine law,

\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}

In order to make the ratio same, even though m∠A>m∠B>m∠C, a must be greater than b and b must be greater than c.

\Rightarrow a>b>c

Also given that its perimeter is 30. Now we have to find out whose side length is 7. So we have 3 cases.

Case-1. Length of a is 7

As a must be the greatest, so b and c must be less than 7. Which leads to a condition where its perimeter won't be 30. As no 3 numbers less than 7 can add up to 30.

Case-2. Length of b is 7

As b is greater than c, so c must 6 or less than 6. But in this case the formation of triangle is impossible. Because the triangle inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. If b is 7 and c is 6, then a must be 17. So no 2 numbers below 7 can add up to 17.

Case-3. Length of c is 7

As this is the last case, this must be true.

Therefore, by taking the aid of process of elimination, we can deduce that side c may have length 7.

What is the height of the building pictured below if its shadow is 100 ft. long?
Evgen [1.6K]
Yeah.. baby, do the SOH CAH TOA with the hula hoop

\bf &#10;sin(\theta)=\cfrac{opposite}{hypotenuse}&#10;\qquad \qquad &#10;% cosine&#10;cos(\theta)=\cfrac{adjacent}{hypotenuse}&#10;&#10;\\ \quad \\&#10;% tangent&#10;tan(\theta)=\cfrac{opposite}{adjacent}&#10;

so.. hmmm we have in the picture, an angle, and two sides,
actually, is the "adjacent" side, and the "opposite"

so.. which  of those ratios give us only
the angle
the adjacent side
the opposite side?

ahhha!, is Ms tangent
so  \bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(42^o)=\cfrac{h}{100}

solve for "h"
