Answer: \dfrac{15}{4}

Step-by-step explanation:

Given

\Rightarrow \dfrac{3}{k}=\dfrac{4}{5}

Apply cross-multiplication

\Rightarrow K=3\times \dfrac{5}{4}=\dfrac{15}{4}\\\\\Rightarrow k=3\ \dfrac{3}{4}

The value of k is \dfrac{15}{4}\ \text{or}\ 3\ \dfrac{3}{4}

the sum of inner angles of a pentagon is equal to

n - 2 \times 180  = (5 - 2) \times 180  \\ 3 \times 180 = 540

so:

x + 10 + x + 20 + 2x + 10 \\  + x + 10 + 2x = 540 \\ 7x + 50 = 540 \\ 7x = 490 \\ x = 70

and the largest one is 150

2x + 10 = 2(70) + 10 = 150

the answer is 1/16

4  {}^{ - 2}  =  \frac{1}{4 {}^{2} }  =  \frac{1}{16}

the parallel line can be

y=2x+4

or any line with different y intercept

good luck

NO LINKS!!!!!!!!! please solve it and explain it.
Usimov [2.4K]

Answer:

Linear: y = 2x-1

Step-by-step explanation:

slope 1 = (5 - -9)/(3 - -4) = 14/7 = 2

slope 2 = (19-5)/(10-3) = 14/7 = 2

equation: y = mx + b          b = y-mx = 19 - 2*10 = -1

y = 2x - 1

Let a_n be the n th digit after the decimal point in
WITCHER [35]
I believe this should just be equal to<span>
9π+5e−<span>(<span>⌊9π+5e⌋</span>)</span>=9π+5e−41</span>
The first element in your sum should be the first digit after the decimal point times .1, so you have
.8
The next element in the sum is the second digit after the decimal place times .01, so you get<span>
.8+.06=.86

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
