Well, this is really simple math.

Divide 7 by 15.

7/15 = 0.46666666666

To make it simple, round to the nearest hundredths.

7/15 = 0.47

60 POINTS PLEASE HELP ITS URGENT 1. Write a quadratic equation that can be solved by factoring. Solve your equation and show and

Vika [28.1K]

you have a quadratic equation that can be factored, like x2+5x+6=0.This can be factored into(x+2)(x+3)=0.

So the solutions are x=-2 and x=-3.

1. Try first to solve the equation by factoring. Be sure that your equation is in standard form (ax2+bx+c=0) before you start your factoring attempt. Don't waste a lot of time trying to factor your equation; if you can't get it factored in less than 60 seconds, move on to another method.
2. Next, look at the side of the equation containing the variable. Is that side a perfect square? If it is, then you can solve the equation by taking the square root of both sides of the equation. Don't forget to include a ± sign in your equation once you have taken the square root.
3.Next, if the coefficient of the squared term is 1 and the coefficient of the linear (middle) term is even, completing the square is a good method to use.
4.Finally, the quadratic formula will work on any quadratic equation. However, if using the formula results in awkwardly large numbers under the radical sign, another method of solving may be a better choice.

Working alone, Ryan can dig a 10 ft by 10 ft hole in 5 hours Castel can dig the same hole in 6 hours how long would it take them

Fed [463]

Answer:

The time taken by both boys to complete work = 2.73 hours

Step-by-step explanation:

Time taken by rayan to dig hole $T_{1}$ = 5 hours

Time taken by castel to dig hole $T_{2}$ = 6 hours

Now the time taken by both persons working together

$T = \frac{T_{1} T_{2} }{T_{1} + T_{2}}$

Put all the values in above formula we get

$T = \frac{ 30 }{6 + 5}$

$T = \frac{30}{11}$

T = 2.73 hours

Therefore the time taken by both boys to complete work = 2.73 hours

Given a right prism where p is the perimeter of the base, h is the height, BA is the area of the bases, and LA is the lateral ar

Ymorist [56]

Let
p ----------------> is the perimeter of the base
h ---------------> is the height
BA-------------> is the area of the bases
LA--------------> is the lateral area

we know that surface area is the sum of base areas plus lateral areas
then
SA=[BA]+P*h
but remember that
LA=P*h
then
SA=[BA]+LA----------> SA=BA+LA

the answer are the options B.) SA=BA+LA and the option D.) SA=BA+ph

Explain why the square root of 64 has a positive and negative value.

weeeeeb [17]

Since the square root of 64 is 8, 8 has an absolute value, so it can be opposites as it, eg. 8 = -8.
