1 answer:

The best approach would be B. make a table. It is the only of the answers that is correct and gives a clear strategy to find the answer. C...? Guessing is never good in math as a rule... and A... well this one is just wrong. You wouldn't be dividing the total by 7, you would be multiplying.

B is your correct answer.

How does one determine a TVs height and width when we only know the diagonal measurement

aliya0001 [1]

Answer:

Diagonal = $\sqrt{w^{2}+h^{2} }$

The diagonal equals the square root of the width squared plus the height squared.

Step-by-step explanation:

With this equation you would then plug in the known measurements and solve it out.

In equilateral ΔABC, AD, BE, and CF are medians. If FO = 4, then AE = A) 4 B) 4 3 C) 8 D) 12

vampirchik [111]

Firstly, we need to draw triangle

we know that

O is a centroid

and centroid divides median into 2:1

so,

$\frac{CO}{FO} =\frac{2}{1}$

we have FO=4

so, we can plug it

$\frac{CO}{4} =\frac{2}{1}$

$CO=8$

now, we can find CF

CF=OC+FO

CF=8+4

CF=12

now, we can see triangle ACF is a right angled triangle

so, we can use pythagoras theorem

$x^2=(\frac{x}{2} )^2+12^2$

now, we can solve for x

$\frac{3x^2}{4}=144$

$x^2=192$

$x=8\sqrt{3}$

Since, it is equilateral triangle

so,

$AC=x=8\sqrt{3}$

we know that

E is a mid-point

so,

$AE=\frac{AC}{2}$

now, we can plug values

$AE=\frac{8\sqrt{3}}{2}$

$AE=4\sqrt{3}$ ................Answer

You can walk 4.4 feet per second. How many minutes will it take you to get to Room 117? Round your answer to the nearest hundred

OverLord2011 [107]

For this problem, I have to know the amount of distance to get to Room 117. If I do, I can give an exact answer to this problem. Through dimensional analysis, you have divide distance with speed to determine the time:

Time = Distance/Speed
Time = d/4

As long as you know the distance, when you substitute it to d in the equation, you can already answer the time.
