Please answer i need help

labwork [276]

Answer:

first answer is 9.84

Step-by-step explanation:

9.84 is the square root of 97, rounded to the nearest hundredth.

the legs measure 9 x 9 and 4 x 4 = 81 and 16.

81 + 16 = 97, so your answer is the square root of 27, which rounded to the nearest hundredth, equals 9.84. Rounding towards the nearest whole, 10 would be your best bet.

hope this helps!!

Last Sunday a certain store sold copies of Newspaper A for $1 and Newspaper B for 1.25. If r percent of the stores revenue came

Oksanka [162]

Answer:

Option 400p/500-p

Step-by-step explanation:

Let the number of newspaper A sold be 'x'

and the number of newspaper A sold be 'y'

Therefore,

Total revenue = $1x + $1.25y

Total newspapers sold = x + y

Therefore,

according to the question

r = $\frac{x}{x + 1.25y}\times100$ ..........(1)

and,

p = $\frac{x}{x + y}\times100$

or

(x + y)p = 100x

or

y = $\frac{x}{p}\times100-x$

or

y = $\frac{x(100-p)}{p}$

substituting y in 1

r = $\frac{x}{x + 1.25(\frac{x(100-p)}{p})}\times100$

or

r = $\frac{100p}{p+125-1.25p}$

or

r = $\frac{100p}{125-0.25p}$

multiply and divide the RHS with 4

we get

r = (400p)÷(500-p)

hence,

Option 400p/500-p

The value of x is a third of the value of 45-10x

Mnenie [13.5K]

Answer:

x = 45/13, also x = 3 6/13

Step-by-step explanation:

is = equal sign

of = multiply

<u>Equation:</u>

$x = 1/3 (45-10x)$

To do this, you could easily do communitive property of multiplication, but to make it more understandable I will use reversing.

1. Simplify. Multiply - Divide.

$x=\frac{45-10x}{3}$

2. Factor out common term 5.

$x=\frac{5(9-2x)}{3}$

3. Multiply both sides by 3.

$3x=5(9-2x)$

4. Expand.

$3x=45-10x$

5. Add <em>10x</em> to both sides.

$3x+10x=45$

Simplify. <em>3x + 10x = 13x.</em>

$13x=45$

Divide both sides by 13.

$x= \frac{45}{13}$

Mixed Number = $x=3\frac{6}{13}$ .

You can also use distributive property. The formula for this problem is: $(\frac{1}{3} * 45) - (1/3*10x)$ .
