What u can do is do 3/63=5/x. so u have to get x all by itself.


3/63=5/x
cross multiply
63×5 and 3×x
315=3x
divide by 3 to the number 315

What is m∠A to the nearest degree?
Anuta_ua [19.1K]
So this is a right triangle so you can use sin, cosine, or tangent. for A, you have the sides opposite and hypotenuse, which means you use sin*
sin(A) = opposite / hypotenuse
sin(A) = 56 / 75
arcsin(56/75) = A
A= about 48.3
so to the nearest degree, your answer is 48

Describe the relationship between the perimeter of a triangle and the perimeter of the triangle that is formed by the midsegment
lilavasa [31]
It is 1/4 of the area of the larger triangle...basically if you connect the three midpoints of the triangle's sides it creates four identical smaller triangles...

The perimeter is one half of the larger triangle...

If a snail crawls 12 centimeters per hour, how long will it take for the snail to travel 1 meter
Pavlova-9 [17]

Answer: 8 1/3 hours or 500 minutes

Step-by-step explanation:

Keep in mind that there are 100 centimeters in a meter.

The snail moves at a pace of 12 cm/h, and needs to go 100 cm.  You can just divide 100/12 to get 8 1/3, which is how many hours (groups of 12 cm) it takes for the snail to travel 100 cm (1 meter).

If necessary, you can also multiply 8 1/3 by 60 to get the number of minutes the snail takes.  8 times 60 is 480, and 1/3 of an hour is 20, so add 480+20 to get 500 minutes.

A box with an open top will be constructed from a rectangular piece of cardboard. The piece of cardboard is 10 inches wide and 1
kupik [55]

Answer:

Domain of the function is  { x : x∈R, x>0 } or (0,∞).

Step-by-step explanation:

It is given that the dimensions of a rectangular piece of cardboard are

Length = 14 inch

Width = 10 inch

The box will be constructed by cutting out equal squares of side x at each corner and then folding up the sides. So the dimensions of the box are

Length = 14-2x inch

Breadth = 10- 2x inch

Height = x inch

The volume of cuboid box is

V=length\times breadth \times height

The volume function of the box is

V=(14-2x)\times (10-2x)\times x

V=(14-2x)(10-2x)x

The volume function is V=(14-2x)(10-2x)x.

It is a polynomial function and domain of a polynomial function is all real numbers.

Here, x represents the height of the box. So, value of x must be a positive real number.

Domain of the function is

Domain = { x : x∈R, x>0 }

It can be written as (0,∞).

Therefore, domain of the function is  { x : x∈R, x>0 } or (0,∞).
