The new length of the string is  (16 + 1/4) feet, then the correct option is the second one (counting from the top)

We know that the current string was (7 + 3/4) feet in length. Then they add another piece that measures 8.5 feet.

The new length of the string is given by the addition of the above two lengths, we will get:

L = (7 + 3/4) feet + 8.5 feet

We can rewrite the second length as a mixed number:

8.5 = 8 + 1/2 = 8 + 2/4

Replacing that we get:

L = (7 + 3/4) ft + 4.5 ft

 =  (7 + 3/4) ft + (8 + 2/4) ft

 = (7 + 8) ft + (3/4 + 2/4) ft

 = 15ft + 5/4ft = 15ft + (4/4 + 1/4)ft = (16 + 1/4)ft

The new length of the string is  (16 + 1/4) feet, then the correct option is the second one (counting from the top)

complete the system that models the heights of the ball and the receiver’s hands over time. h = -16t² + 14t + h = -16t² + t +
adoni [48]

The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

A quarterback throws a football toward a receiver from a height of 6 ft. The initial vertical velocity of the ball is 14 ft/s. At the same time that the ball is thrown, the receiver raises his hands to a height of 8 ft and jumps up with an initial vertical velocity of 10 ft/s.

The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8

In anticipation of receiving a fertilized ovum, the lining of the uterine wall
Mariulka [41]

Every month, the lining of the uterus becomes thicker in preparation for an egg that has been fertilized to place itself there. In the event that this transpires, hormones originating from the reproductive organs will stabilize the vascular tissue of the endometrium, which in turn will offer a setting for the embryo to grow in.

This is further explained below.

<h3>What is the uterine wall?</h3>

Generally, The uterine lining grows every month in anticipation of the implantation of a fertilized ovum. When this happens, the endometrium's vascular tissue is stabilized by hormones from the reproductive organs, providing an environment for the growing fetus.

In conclusion, There are three distinct layers of muscle tissue that compose the uterine wall. The muscle fibers are intertwined with the connective tissue of blood vessels, elastic fibers, and collagen fibers, and they may run in either of three directions: longitudinally, circularly, and obliquely. As the baby grows within the uterus, this thick muscular wall begins to stretch out and eventually becomes much thinner.
