It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.

April shoots an arrow upward at a speed of 80 feet per second from a platform 25 feet high. The pathway of the

zaharov [31]

Answer:

The maximum height of the arrow is 125 feet.

Step-by-step explanation:

The pathway of the arrow can be represented by the equation,

$h = -16t^2 +80t + 25$ .....(1)

Where h is height in in feet and t is time in seconds.

It is required to find the maximum height of the arrow. For maximum height, $\dfrac{dh}{dt}=0$ .

So,

$\dfrac{d(-16t^2 +80t + 25)}{dt}=0\\\\-32t+80=0\\\\t=\dfrac{80}{32}\\\\t=2.5\ s$

Put t = 2.5 s in equation (1). So,

$h = -16(2.5)^2 +80(2.5) + 25\\\\h=125\ \text{feet}$

So, the maximum height of the arrow is 125 feet.

A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 40% off clearan

Hatshy [7]

Answer: He would pay 45% of the original price.

Step-by-step explanation:

Since we have given that

Let the original price of item be 'x'

Rate mark down by 25%

Amount of marked down would be

$\dfrac{25}{100}\times x\\\\=0.25x$

Amount after marked down becomes

$x-0.25x\\\\=0.75x$

Additional clearance items by 40% off

Amount of additional off is given by

$\dfrac{40}{100}\times 0.75x\\\\=0.4\times 0.75x\\\\=0.3x$

After additional off, the amount becomes,

$0.75x-0.3x\\\\=0.45x$

Hence, he would pay 45% of the original price.
