Mathematics
1 answer:
Elden [556K]3 years ago
4 0

Answer:

B. SAS

Step-by-step explanation:

In the given diagram, it would be observed that each side of the bigger triangle are multiplied by a factor of \frac{1}{3} to give the values of each corresponding sides of the smaller triangle. But the included angle of the two triangles are the same.

Therefore, the reason why the triangles are similar is because of side-angle-side (SAS) relations. The correct option is B.

Which division sentence is related to the product of a/3(a/3) when a≠0
Mashcka [7]

Answer:

\frac{a}{3} \frac{.}{.}\frac{3}{a} =1

Step-by-step explanation:

As we seen that the reciprocal of the a/3(a/3) provides the result as a product number that gives the output as 1 .

Also we know that two fractions number gives output 1 if they are the reciprocal or multiplicative inverse from each other.

So,  a/3(a/3

\frac{3a}{3a} \\\\it\ can\ be \ written \ as \\\frac{3}{a} \frac{.}{.}\frac{a}{3}=\ 1

What is the slope of a line perpendicular to the line whose equation is
Marina86 [1]

Answer:

The slope of a line perpendicular to the line whose equation is 4x - 5y = 10 is -5/4.

Step-by-step explanation:

provided the equation;

4x- 5y=10.(let it be equation of line1 )

and the other line be line2

from perpendicularty principle

M1×M2= -1

BUT for M1(slope of line L1)

y= mx+c

where "c" is constant value.

"m" is slope.

therefore

5y= 4x - 10

(dividing by five throughout)

y=(4x/5) - 2

y= (4/5)x - 2

therefore M1= (4/5)

Returning back to our principle

M1×M2= -1

(4/5)M2=-1

<u>M2= -5/4</u>

4. A local DVD rental machine rents
Mrrafil [7]

It takes 16 movie rentals for both options to be the same  price

<u>Solution:</u>

Given that, A local DVD rental machine rents movies out to customers for $5.75 per movie.  

A digital movie company allows you to rent movies for $3.25 but requires a membership fee of $40.  

We have to find how many movie rentals will it take for both options to be the same price?  

Now, let the number of movies rented be "n"

Then, according to the given information,

\begin{array}{l}{5.75 \times n=3.25 \times n+40} \\\\ {5.75 n=3.25 n+40} \\\\ {5.75 n-3.25 n=40} \\\\ {2.50 n=40} \\\\ {n=\frac{40}{2.5}=16}\end{array}

Hence, it takes 16 movies to be the same price for both options.
