Given:

The actual length of side y is 22cm.

To find:

The length of side x by using the scale drawing.

Solution:

We know that the corresponding sides of original figure and scale drawing are proportional.

$\dfrac{x}{1.8}=\dfrac{y}{1.4}$

$\dfrac{x}{1.8}=\dfrac{22}{1.4}$

$x=\dfrac{22}{1.4}\times 1.8$

$x\approx 28.286$

Therefore, the length of side x is about 28.286 cm.

Answer:

The quotient = 4x - 17 and the remainder = 54

Step-by-step explanation:

$\frac{4x^{2}-5x+3 }{x+3}=4x+\frac{-17x+3}{x+3}$

$\frac{-17x+3}{x+3}=-17+\frac{54}{x+3}$

The quotient = 4x - 17 and the remainder = 54

What ratio forms a proportion with 14/42? A. 1/4 B. 7/21 C. 12/40 D. 28/80

koban [17]

Hey there!

"What ratio forms a proportion with $\frac{14}{42}$ ?"

- $\frac{14}{45} =0.56$ (for the decimal)

$A) \frac{1}{4}$ $=0.25$ $(incorrect)$
$B) \frac{7}{21}$ $=0.33$ $(Incorrect)$
$C) \frac{12}{40}$ $0.3$ $(incorrect)$
$D) \frac{28}{80}$ $0.7$ $(incorrect)$

But in order for you to solve this particular equation you'd have to go in with two (like multiplying by two)

$1\times2= 2$ ; $4\times2 = 8$ $(incorrect)$
$7\times 2= 14$ ; $21\times2 = 42$ $(correct)$
$12 \times2 = 24$ ; $40\times 2 = 80$ $(incorrect)$
$2 \times 28 = 56$ ; $2\times 80 = 160$ $(incorrect)$

Your result: $\boxed{Answer: B. \frac{7}{21} }$

Good luck on your assignment and enjoy your day!

Help pls I no it’s simple but I don’t understand pls look at the pictures or image pls pls number 1 pls

Answer: The answer would be No, Yes, No.

Step-by-step explanation:

Look at the grid, you can see that it has 100 units in all.

0.42 equals 21/50, so they are both wrong. The denominator would have to be 100. The only logical one would be the second one.

What is the first step to 7(x – 4) = 84.

ss7ja [257]

Parenthesis according to the PEMDAS rule

So
7(x - 4) = 84

Would be

7x -28 = 84

Hope this helped :)

Determine determine whether the following geometric series converges or diverges. if the series converges find its sum.

Lilit [14]

For starters,

$\dfrac{3^k}{4^{k+2}}=\dfrac{3^k}{4^24^k}=\dfrac1{16}\left(\dfrac34\right)^k$

Consider the $n$ th partial sum, denoted by $S_n$ :

$S_n=\dfrac1{16}\left(\dfrac34\right)+\dfrac1{16}\left(\dfrac34\right)^2+\dfrac1{16}\left(\dfrac34\right)^3+\cdots+\dfrac1{16}\left(\dfrac34\right)^n$

Multiply both sides by $\frac34$ :

$\dfrac34S_n=\dfrac1{16}\left(\dfrac34\right)^2+\dfrac1{16}\left(\dfrac34\right)^3+\dfrac1{16}\left(\dfrac34\right)^4+\cdots+\dfrac1{16}\left(\dfrac34\right)^{n+1}$
