ASAP PLEASE HELP!! “Find the quotient”
elena-14-01-66 [18.8K]

Answer:

The quotient is \frac{x(2x-3)}{7} answer (D)

Step-by-step explanation:

\frac{2x-3}{x} ÷ \frac{7}{x^{2} }

In division with fractions we reverse the fraction after division sign and change division sign to multiplication sine

\frac{2x-3}{x} × \frac{x^{2} }{7}

\frac{2x-3}{1} × \frac{x}{7}

\frac{x(2x-3)}{7}

Find thhe remainder when 7^203 is divided by 4
Aleksandr [31]
Using the square-and-multiply approach, we have

7^{203}=7\times(7^{101})^2
7^{101}=7\times(7^{50})^2
7^{50}=(7^{25})^2
7^{25}=7\times(7^{12})^2
7^{12}=(7^6)^2
7^6=(7^3)^2
7^3=7\times7^2

and so, using the property that, if a_1\equiv b_1\mod n and a_2\equiv b_2\mod n, then a_1a_2\equiv b_1b_2\mod n, we get

7\equiv3\mod4
7^2\equiv9\equiv1\mod4
7^3\equiv7\times1\equiv7\equiv3\mod4
7^6\equiv9\equiv1\mod4
7^{12}\equiv1\mod4
7^{25}\equiv7\times1\equiv7\equiv3\mod4
7^{50}\equiv9\equiv1\mod4
7^{101}\equiv7\times1\equiv7\equiv3\mod4
7^{203}\equiv7\times9\equiv3\times1\equiv3\mod4

In ABC, m∠A=10 and m∠B=145. Select the triangles that are similar to ABC.
Tanya [424]

Answer:

A

Step-by-step explanation:

A triangle has 180 degrees.

So, 10 + 145 + x = 180

x = 25

This means that the angles in the triangle are:

10, 145, and 25

Using this information, only A has the same values so it is the answer
