The value of the angle ∠BCA when approximated to 3 significant figures is;  20.4°

From the attached image of the triangle ABC showing the side lengths x and y, we can see clearly that it is a right angle triangle.

Now, since we want to find the value of the angle ∠BCA, then it means we have to use trigonometric ratio to get;

x/y = sin BCA

Plugging in the relevant values gives us;

8/23 = sin BCA

∠BCA = sin⁻¹(8/23)

∠BCA = 20.355

Approximating to 3 significant figures gives us;

∠BCA = 20.4°

Using a linear function, it is found that you would need roughly 24 hours of training to have a monthly pay of $1500.

A linear function is modeled by:

y = mx + b

In which:

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.

Answer:

The equation representing the proportional relationship between j and m is m = 3j/4 .

Step-by-step explanation:

Writing an Equation to Represent a Proportional Relationship

What is proportional relationship?

A proportional relationship between two quantities is when the two quantities vary directly with one and other. Meaning if one item is doubled, the other item is also doubled.

Going back to the given problem above, we have the table showing the proportional relationship between j and m.

j | 4 | 12 | 20 |

m | 3 | 9 | 15 |

Solution:

Step #1

The proportional relationship can be written as:

m/j = ¾ = ‌9⁄12‌ = ‌15⁄20‌ = ¾

Step #2

So, the equation representing this proportional relationship is:

m = ¾ × j/1 = 3j/4

Final Answer:

The equation representing the proportional relationship between j and m is m = 3j/4 .

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

If m has exactly 5 positive divisors then there can only be one prime factor.

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

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.

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).

It also means that the motorcycle took 4 hours to travel 280 miles, and the car took 3 hours more, or 7 hours to travel the same distance.

Answer:

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

2.50x+1.25y=z

Step-by-step explanation:

Let the number of juice bottles = x

And the number of containers of popcorns=y

And the total number of juice bottles and containers of popcorns=z

Total number of juice bottles=x times $2.50

Total number of containers of popcorn= y times $ 1.25

equation; 2.50x+1.25y=z

The linear equation that best fits the data is: y = 10x + 15.

First, find the slope/unit rate (m) and the y-intercept/starting value, then substitute the values into y = mx + b.

Using two points on the graph, (1, 25) and (2, 35), find the slope (m):

Slope (m) = (35 - 25)/(2 - 1)

Slope (m) = 10/1

Slope (m) = 10

Substitute (x, y) = (1, 25) and m = 10 into y = mx + b to find b

25 = 10(1) + b

25 - 10 = b

b = 15

Substitute m = 10 and b = 15 into y = mx + b

y = 10x + 15
