Which of the following will be the ratio of the perimeter of the blue triangle to the red triangle.
Kazeer [188]

The ratio (red to blue) of the perimeters of the similar triangles is 12:7

Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.

Perimeter of a triangle = s1 + s2 + s3

For the red triangle;

Perimeter of the red triangle = 12 + 12 + 12

Perimeter of the red triangle = 36

For the blue triangle:

Perimeter of the blue triangle = 7 + 7 + 7

Perimeter of the blue triangle = 21

Taking the ratio of their perimeters;

Ratio of red to blue = 36:21 = 12:7

Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

The girl in the picture is at the highest point in swinging and starts to come down. Which statement best describes the changes
SpyIntel [72]

When she descends the potential energy will decrease at the same rate that the kinetic energy increases.

<h3></h3><h3>How to describe changes in energy?</h3>

We know that we can write the total energy of a moving object as:

E = U + K

Where U is the potential energy and K is the kinetic energy.

In the given case, U will only depend on the height of the girl and it will be maximized when the height is maximum.

K = (1/2)*m*v^2

where m is the mass and v is the velocity.

When the girl is at the highest point, the velocity becomes equal to zero. This happens because at that point she stops going up and starts going down, so the velocity must be zero at that moment.

Then we have K = 0.

E = U.

As she starts going down, the velocity starts increasing and the height decreases, thus, the kinetic energy increases and the potential energy decreases. This relates to the conservation of energy. E will always be the same value, but K and U will depend on the position of the girl.

This means that if the potential energy decreases a quantity e', then the kinetic energy must be increased by that same amount.

because parts washers use cleaning solutions that eventually become spent, they must be disposed of properly.
kipiarov [429]

Jose and zola want to purchase their first home. Jose makes $23. 50 an hour and works 40 hours per week. Zola makes $21. 50 an h
PolarNik [594]

Based on the computation done, the value of the combined gross monthly income is $7630.

Since there are four weeks in a month, Joe's income will be:

= 23.50 × 40 × 4

= 3760

The value of Zola's income will be:

= 21.50 × (40 + 5) × 4

= 21.50 × 45 × 4

= 3870

Therefore, the combined gross monthly income will be;

= $3760 + $3870

= $7630
