Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water.
represents the volume of water Andrei uses (in liters) if he uses marbles.
What is the glass tank's volume?
______________liters
Answer: the amount of liters that would fill the glass tank's volume can not be found
Step-by-step explanation:
there is not enough information to find out how many liters could fill the glass tanks volume
The required volume of glass tank = Vb +Vw liters
Volume, is defined as the ratio of the mass of object to its density.
Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water.
Volume of pebbles = Vb
Volume of water = Vw
Volume of glass tank = Vg
Vg = Vb + Vw
Thus, the required volume of glass tank is = Vb + Vw liters

a ramp is 17 feet long, rises 8 feet above, and a covers a horizontal distance of 15 feet as showed in the figure. the ratio of to is equal to tan B
Using relations in a right triangle, it is found that:
The ratio of 8 to 15 is equals to tan B.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.Researching the problem on the internet, we have that:
The side opposite to angle B has a length of 8 feet.The side adjacent to angle B has a length of 15 feet.Hence the tangent of B is:
tan(B) = 8/15.
Which means that:
The ratio of 8 to 15 is equals to tan B.

Find the value of x:
X

Applying the definition of similar triangles, the value of x is determined as: 12.5.
What are Similar Triangles?In a triangle like the one shown above, the line that intersects the two sides of the triangle divides the two sides of the triangle to form similar triangles. Thus, their corresponding sides are proportional to each other.
Therefore, we would have:
(x + 5) / 5 = (10 + 4) / 4
(x + 5) / 5 = 14/4
4(x + 5) = 5(14)
4x + 20 = 70
4x = 70 - 20
4x = 50
x = 50/4

A boy walks 58 feet up a ramp having a 22.5 degree inclination. how high is he standing from the ground?
Boy is 22.5 feet high from the ground
The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.
The given question can be solved by sin, as value of perpendicular is to be evaluated and height and angle is provided. Let height from the ground be x
sin(22.5°) = x / 58
x = 58sin22.5 = 58(.38258) = 22.5 feet high.
Thus the Boy is 22.5 feet high from the ground.

0 = 3 ( x-1)(x+7) so you can see this = 0 when x =1 or when x = -7
these are the x-axis intercepts
the vertex will be right in the middle between the intercepts found above ....... at x = -3
plug this value in to find the y coordinate 3 ( -3-1)(-3+7) = -48

a square room has a area of 49 square feet the height of the room is 4 feet. what is the area of one wall
Answer:
28 ft^2
Step-by-step explanation:
The room is in the shape of a square. That means the base of the room (width and length) will have the same dimensions.
Length x Width = 49 ft^2
Length = Width
Length^2 = 49 ft^2
Length = 7 feet
Width is also 7 feet
The height of the room is 4 feet, plenty for non-humans. One wall area would be (7 ft)*(4 ft) = 28 ft^2

Slope is negative, the other must be positive due to m1 x m2 = - 1
m1 = -2/5
The diagram shows a gradient of -2/5. So, the
reciprocal of this valve to make - 1 is 5/2 (which is the - 2/5 flipped upside down, but positive)
-2/5 x 5/2 = - 10/10 (or - 1)

According to the table, how many hours of training would you need to have a
monthly pay of $1500?
Using a linear function, it is found that you would need roughly 24 hours of training to have a monthly pay of $1500.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Looking at the table, the pay increases $200 each 10 hours of work, hence the slope is:
m = 200/10 = 20
Then:
y = 20x + b
When x = 10, y = 1220, hence:
y = 20x + b
1220 = 20(10) + b
b = 1020.
Then the pay for x hours of training is:
y = 20x + 1020.
For a pay of $1500, we have that:
y = 20x + 1020.
1500 = 20x + 1020.
20x = 480
x = 24
You would need roughly 24 hours of training to have a monthly pay of $1500.

According to statement
m has exactly 5 positive divisors AND
Let A^p,B^q,.... are the possible factors of integer m then
assume that p and q ≥ 1.
then the number of possible divisors cannot be 5 because there are no two integers p, q ≥ 1, such that (p +1)(q + 1) = 5

A motorcycle traveling at 70 miles per hour overtakes a car traveling at 40 miles per hour that had a three-hour head start. How far from the starting point are the two vehicles.
----------------------
The car is 120 miles away when the motorcycle starts.
The bike gains on the car at 30 mph (70-40).
It takes 4 hours for the bike to close the gap (120/30).
In 4 hours, the bike and the car are 280 miles from the starting point.
---------
4*70 = 280
7*40 = 280
Since Distance = Speed x Time, and in this case, the distances are equal, we, therefore, have: 70T = 40(T + 3)
70T = 40T + 120
30T = 120
T=4, which makes the distance that both vehicles traveled, highlight_green280miles, calculated as (70 * 4), or (40 * 7).
