Step-by-step explanation:

60 cookies with 4 cups

that means 60 per 4 = 60/4 = 15

and that means that he can make 15 cookies with 1 cup.

that is clear : from 60/4 we immediately know 15/1.

and now, as we know how many cookies can be made with 1 cup, it is easy to say how many cookies can be made with 3 cups. right, 3 times a much.

so, yes, we multiply 15 by 3 and get 45 cookies as answer.

Q. A regular Hexagon has reflection symmetry : True!

Because,
A shape has reflection symmetry only when it has one or more lines of symmetry.

A line of symmetry is a line that passes through a figure such that it splits the figure into two congruent halves.

The United States has trained some of the world's best computer programmers and technology experts. Despite all of this training

Finger [1]

Step-by-step explanation:

1. Many state students are looking for employment opportunities through outsourced jobs in other countries, since their possibilities have been reduced within their own country.

2.One of the independent variables is outsourced work.

a. a type of moderate independent variable.

3. The analysis of the high demand for outsourcing.

a. Control dependent variable.

4.It is an experimental design.

Because you want to see if the outsourced market really has any effect on the US economy.

6. Possible dependent variables such as the effect on the US market or the creation of new markets, I do not consider to be reliable variables to measure the cause or independent variable.

7.It is ecologically valid in the sense that it allows visualizing a positive impact on a way of working that allows reducing costs in all senses, both monetary and transportation, contributing to the care of nature.

8.I do not consider that cause and effect can be claimed.

a.While the one that exitates this type of outsourced work from many parts of the world, this does not guarantee that it is the only source of income for a person, since these outsourced jobs often represent additional income.

9. Focal groups.

2. From the top of a vertical cliff 40 m high, the object is 59.3m from the base of the cliff. Find the angle of depression to t

ArbitrLikvidat [17]

$34^{\circ}$ is the angle of depression from the vertical cliff.

Option: A

Step-by-step explanation:

Given that, Height of the cliff (opposite side) = 40m

Distance of object from the base of the cliff (adjecent side) = 59.3m

To find the angle of depression of the object. From trigonometric rule in a right angled triangle, we know that $\tan \theta=\frac{\text { opposite side }}{\text { adjecent side }}$ $\theta=\tan -1 \frac{\text { opposite side }}{\text { adjecent side }}$ Angle of depression = $\tan -1 \frac{\text { height of cliff }}{\text { Distance of object from the base of the cliff }}=\tan ^{-1} \frac{40}{59.3}=34^{\circ}$ Therefore, the angle of depression to the object is $34^{\circ}$ .
