Answer:

105cm

Step-by-step explanation:

Call the rat's height r, the cat's height c and the table height t.

The left part says that

(t + c) - (0 + r) = 120 = t + c - r

c - r = 120 - t

Right part says that (t + r) - (0 + c) = 90 = t + r - c

c - r = t - 90

120 - t = t - 90

2t = 210

t = 105

Before offering imaging programs, practitioners need to be aware of the reasons why exercise participants are doing it.

<h3>Define imagery in sports.</h3>

When we use imagery, we simulate an actual situation in our minds rather than actually going through it. It differs significantly from daydreaming or simply thinking about anything because it is a cognitive activity that is consciously used by an athlete or exerciser to accomplish a certain task.

In this study, an analysis of secondary data from a recently published randomized controlled trial. In a community-based, group-mediated physical activity intervention for sedentary people 50 and older, the Active Adult Mentoring Program (AAMP) tested the effectiveness of peer volunteers as delivery agents. The AAMP was built on the social-cognitive and self-determination theories, and mentors were trained to lead discussions in groups that would help reinforce key ideas from both theories.

The adaptability of images makes it useful at different times and in varied settings. Athletes employ imagery most frequently right before a competition or during practice, but they do so during the entire season, including the off-season. Similar to how it's reported by athletes, visualization is frequently used before an activity session. For example, it would be more effective for a swimmer to mentally practice her race start by adopting the proper position on the starting block at the swimming pool, as opposed to sitting on a chair at home. Both types of people will typically imagine within the sport and exercise environment where the benefits of this technique are maximized.

Mid-point= $( \frac{ x_{1}+ x_{2} }{2} ,\frac{ y_{1} y_{2} }{2}$
Mid-point=( $\frac{5+(-3)}{2} , \frac{9+7}{2}$
Mid-point=(1, 8)

Find the value of x in the isosceles triangle.

vichka [17]

Answer:

Step-by-step explanation:

The total length of triangle is 40 in. The length of the right triangle is the total length divided by 2 which 40/2 = 20.

We have 2 right triangles. We can use the pythagorean theorem to solve for x.

a^2 + b^2 = c^2

x^2 + 20^2 = 25^2

x^2 + 400 = 625

- 400 - 400

x^2 = 225

x = 15

Find the volume on the following prims it says please help me!! I need to find the volume :)

Delvig [45]

Answer:

V = 277.088 m³

Step-by-step explanation:

Volume of Cylinder Formula: V = πr²h

We are given <em>r</em> = 4.2 and <em>h</em> = 5, so simply plug it into the formula and solve:

V = π(4.2)²(5)

V = 17.64π(5)

V = 88.2π

V = 277.088
