Answer: The required number is 52 and the correct option is

(A) 9+x\div 2=35.

Step-by-step explanation:  Given that the sum of 9 and half a number equals 35.

We are to find the number and also to select the correct translation.

Let x represents the required number.

Then, according to the given information, the equation can be written as :

9+\dfrac{1}{2}x=35\\\\9+x\div 2=35~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

The solution of equation (i) is as follows :

9+x\div 2=35\\\\\Rightarrow 9+\dfrac{x}{2}=35\\\\\Rightarrow \dfrac{x}{2}=35-9\\\\\Rightarrow \dfrac{x}{2}=26\\\\\Rightarrow x=2\times26\\\\\Rightarrow x=52.

Thus, the required number is 52 and the correct translation is 9+x\div 2=35.

Option (A) is CORRECT.

Answer:

Max vol = 2 cubic metres

Step-by-step explanation:

Given that from a square piece of cardboard paper of area size 9 m2 , squares of the same size are cut off from each corner of the paper.

Side of the square = 3m

If squares are to be cut from the corners of the cardboard we have the dimensions of the box as

3-2x, 3-2x and x.

Hence x can never be greater than or equal to 1.5

V(x) = Volume = V(x) = x(3-2x)^2\\= 9x+4x^3-12x^2

We use derivative test to find the maxima

V'(x) = 9+12x^2-24x\\V"(x) = 24x-24\\

Equate I derivative to 0

9+12x^2-24x=0\\x=1/2,3/2

If x= 3/2 box will have 0 volume

So this is ignored

V"(1/2) <0

So maximum when x =1/2

Maximum volume

=9(1/2)+4(1/2)^3-12(1/2)^2\\=2 cubic metres

You have 10 eggs you crack 2 cook 2 and eat 2 how many eggs do you have left?
Alexeev081 [22]

Answer:

Wouldn't it be 8?

Step-by-step explanation:

You crack 2 eggs and cook them, then eat them. If we cracked 2 eggs, cooked 2 different eggs, and ate 2 different eggs, that doesn't make sense.

Which equation has a graph perpendicular to the graph 7x=14y-8
IrinaVladis [17]
<span>Slope-intercept form is y = mx + b
m is the slope 
b is the y-intercept 

7x = 14y - 8

7x + 8 = 14y {added 8 to each side}
(1/2)x + (8/14) = y
slope is 1/2 

A line perpendicular would have a slope of -2 {the negative reciprocal of 1/2} 

#1 y = -2x - 7 {it is the only one with a slope of -2}</span>

Answer:

(-1,3)

Step-by-step explanation:

Thus;

When (-1,3) is placed in the relation 3x + y =0,the answer will be zero.

<h3>Calculations</h3>

Let;

x= -1

y= 3

3(-1) + 3 =0

-3 + 3 = 0
