What is the length of the rectangle?

gregori [183]

Step-by-step explanation:

$area \: of \: rectangle \: = 60 \: {yards}^{2} \\ \therefore \: (w + 4) \times \: w = 60\\ \\ \therefore \: {w}^{2} + 4w -60 = 0 \\ \\ \therefore \: {w}^{2} + 10w - 6w -60 = 0 \\ \\ \therefore \: w({w} + 10) - 6(w + 10)= 0 \\ \\ \therefore \: ({w} + 10) (w- 6)= 0 \\ \therefore \: {w} + 10 = 0 \: or \: w- 6 = 0 \\ \therefore \: {w} = - 10 \: or \: w = 6 \\ \because \: sides \: of \: rectangle \: cant \: be \: negative \\ \therefore \: w \neq \: - 10 \\ \\ \therefore \: w = 6 \\ \\ \therefore \: w + 4 = 6 + 4 = 10 \\ \\ length \: of \: rectangle \: = 10 \: yards.$

Answer: 80%

80,000 = 100%

20,000 = 20%

100% - 20% = 80%

Always convert the main number into 100 and follow through with the other numbers

Jason has already used 4/12 cans of paint while painting furniture. He is painting chairs which each use 10/6 cans of paint.

Lady bird [3.3K]

Answer:

Based off of the calculations I did, I got 32 as the answer.

Step-by-step explanation:

Jason uses 10/6 of the paint for each chair he paints and according to the question, there are 19 chairs.

So we multiply these two numbers to get the amount of paint used after painting all 19 chairs.

10/6 * 19 = 31.666...

Then we add the previous amount Jason used for painting the furniture to the total amount of paint used after painting the 19 chairs.

31.666... + 4/12 = 32.

Thus, Jason used 32 cans of paint in total.

oksian1 [2.3K]

Answer:

$-\frac{3}{4}$ meters

Step-by-step explanation:

From the answer choices, we basically need to find which of them is between $-\frac{1}{2}$ and $-1\frac{2}{3}$

<em>Converting all of them to decimals would make it really easier:</em>

<em />

<em>So we need to find number between -0.5 and -1.67</em>

<em />

<em>Answer choice A is -2.33</em>

<em>Answer choice B is -0.75</em>

<em>Answer choice C is -0.25</em>

<em>Answer chioce D is -1.83</em>

<em />

<em>So which number, from the choices, is between -0.5 & -1.67?</em>

Clearly, it is -0.75, or, $-\frac{3}{4}$ meters
