4. Ashley claims that if she triples the side length of a square (s), the area of the square will also be tripled. Do you agree?

stepladder [879]

Answer :-

Let the side of the square measure a cm, thus, according to the question,

New length = 3(a cm)

We know that,

➭ Area ( Square ) = a²

Thus, the area of the square with normal length i.e. a cm, will be,

⤳ Area = a x a

⤳ Area = a²

Now, by taking the new length, the area will become,

⤳Area = 3a x 3a

⤳ Area = 9a²

Now,

We observe that, if we divide these, we get,

➤ 9a²/a²

( a² will get canceled since its common )

Thus, the ratio becomes,

➭ 9 : 1 = Area square with tripled length : Area of square

Thus, the area will increase by 9 times, and not 3.

Hence, Ashley's assumptions are wrong.

The diagram rerpesents responses to a survey that include statements p and q . Which statement is true?

BARSIC [14]

Answer:

C. The number of responces $p\vee q$ is also 46

Step-by-step explanation:

Note that:

$p\wedge q$ means both p and q must hold;
$p\vee q$ means either p or q must hold.

From the diagram,

the number of responses $p\wedge q$ is 46;
the number of responces $p\vee q$ is also 46;
the number of responces $p\setminus q$ is 0;
the number of responces which are neuther p nor q is 20.

So, you can state that the correct answer is C

I need help with this please i have a test

Equation : (7x-4)+(3x-3)+(x) = 180
In the equation the sum of the internal angle in the triangle is 180 degrees. Use this equation to figure the sum of angle in any quadrilateral 180*(number of sides-2)
Solve the equation
Put all similar variable on one side
7x+3x+x-4-3=180
11x-7=180
11x=180+7
11x=187
x = 187/11
x = 17
Now find the angles by plugging in x
Angle F (7*17-4) = 115 degrees
Angle G (x) = 17 degrees
Angle E (3*17-3) = 48 degrees
If you add 115+48+17 you will get a sum of 180 this shows your answer is right

Angle F = 115
Angle G = 17
Angle E = 48
