Answer:

You will need 39 nickels and 13 dimes.

Step-by-step explanation:

First you would find the number by choosing a number for example 10 so 10*5 which is 50 cents because, we are talking money here

So 39*5=195 which converts to $1.95

Next you would write that number down and divide 39 by 3 which would be 13

Then 13*10 would be 130 which would be converted into $1.30

Lastly you would add $.195 and $1.30 which would be $3.25

Therefore your answer is 39 nickels and 13 dimes

3d=n

10d+5n=325

10d+15d=325

25d=325

d=13

n=39

Hope this helps.

頑張って!

Prove that <br><img src="https://tex.z-dn.net/?f=4cot45%20%5E%7B2%7D%20%20-%203tan%20%5E%7B2%7D%2060%20%2B%202sec%20%5E%7B2%7D60
sesenic [268]

Answer:

4 \cot {}^{2} (45)  - 3 \tan {}^{2} (60)  + 2 \sec {}^{2} (60)  = 3 \\

LHS = 4 \cot {}^{2} (45)  - 3 \tan {}^{2} (60)  + 2 \sec {}^{2} (60)  \\

let us first take a look at the values of the trigonometric ratios given in the question so that we get quite clear about what is to be done.

here ,

\cot(45)  = 1 \\  \\  \tan(60)  =  \sqrt{3}  \\  \\  \sec(60)  = 2

now ,

we just have to plug in the values considering certain other things given in the question and we're done!

so let's start ~

4(1) {}^{2}  - 3( \sqrt{3} ) {}^{2}  + 2(2) {}^{2}  \\ \\ \dashrightarrow \: 4(1) - 3(3) + 2(4) \\ \\ \dashrightarrow \: 4 - 9 + 8 \\\\ \dashrightarrow \: 12 - 9 \\ \\\dashrightarrow \: 3 = RHS

hence , proved ~

hope helpful :D

Given: In triangle ABC, ∠B ≅ ∠C Prove: AB ≅ AC Complete the paragraph proof. We are given that ∠B ≅ ∠C. Assume segment AB is not
ELEN [110]

Answer:    

Given: Here ABC is a triangle,

In which \angle B \cong \angle C

Prove: AB \cong AC

Let us assume AB is not congruent to AC.

If AB > AC,

Then m\angle C > m\angle B ( By the converse of the triangle parts relationship theorem )

If  If AB < AC, then m\angle C < m\angle B  ( by the converse of the triangle parts relationship theorem. )

But, by the definition of congruent,

We know \angle B \cong \angle C ( by the given statement.)

Therefore, we have a contradiction,

And, AB \cong AC  and AB = AC.
