Answer:
2km/hr
Step-by-step explanation:
The formula for calculating speed is expressed as;
Speed = Distance/Time
Given the following;
Distance = 6km
Time = 3hours
Speed = 6km/3hr
Speed = 2km/hr
Hence the speed travelled is 2km/hr

c = 49 cm, a = 41°. Find B in degrees. Round to 2 decimal places.
Answer:
49.03 degrees
Step-by-step explanation:
c = 49, [tex]\alpha[/tex] = 41
We can solve for [tex]\beta[/tex] if we first find b.
Remember: SOH CAH TOA
Cosine = Adj/Hypotenuse
So, Cos (41) = b/49
49 x (Cos 41) = b
49 x .755 = b
b = 36.99
sin [tex]\beta[/tex] = Opp/Hyp = b/49 = 36.99/49 = .755
β = inverse sin (.755) = 49.03° (Inverse sin is designated by sin⁻¹ on your calculator)

Step-by-step explanation:
which equation represents a linear function? y=4/x+1, y=2/3x -1/2
Answer:
y = 2/3x - 1/2
Step-by-step explanation:
y = 2/3x - 1/2 is a linear function. It contains a slope and a y-intercept and every x value will produce a unique y value.
y = 4/x + 1 is a rational function, as it contains a fraction.
Answer:
y = 2/3x - 1/2
Step-by-step explanation:
y = 2/3x - 1/2 is a linear function. It contains a slope and a y-intercept and every x value will produce a unique y value.
y = 4/x + 1 is a rational function, as it contains a fraction.

If you have a robot arm that is 10 inches long, and a motor that lifts 100 ounces, how much torque is this?
Answer:
I hope its help U
Step-by-step explanation:
As we know the formula of torque
T= R*F
given R-=10 inches = 0.254 meter
Force=100 ounce=27.80 newton ( we convert unit to Si - system)
Now putt the values in above equation and multiply we get
T=0.254*27.80
T=7.061 newton-meter
if u want to get the answer in ounce and inches then simply convert the units u will get ,
T=1000 ounce-inches
What value of y would make {(-2, 18), (3, y), (6, 6), (-18, 2), (4, 9)} an inverse variation?
Answer:
The value of "y" the would make the ordered pairs an inverse variation is;
y = 12
Step-by-step explanation:
The given ordered pairs are;
{(-2, 18), (3, y), (6, 6), (-18, 2), (4, 9)}
When a pair of variables, "x" and "y", vary inversely to one another, as the value of one variable increases, the value of the other variable decreases
Mathematically, we have;
y ∝ 1/x
The above relation can be represented as an equation as follows;
y = k/x
Where;
k = The constant of proportionality
Therefore, k = y·x
From the given ordered, we have;
k = -2 × 18 = -36
k = 6 × 6 = 36
k = -18 × 2 = -36
k = 4 × 9 = 36
Therefore, the value of "k" is made constant as follows;
The inverse variation is y = k/(x × (-1)ⁿ)
Where;
n = The number of the term
Therefore, y = 36/(3 × (-1)²) = 12
y = 12
The given ordered pairs can therefore be written as follows;
{(-2, 18), (3, 12), (6, 6), (-18, 2), (4, 9)}.

Find the value of x in 4:x::x:16
Given:
4:x::x:16
To find:
The value of x.
Solution:
We have,
4:x::x:16
It means, we have
4:x = x:16
It can be rewritten as
[tex]\dfrac{4}{x}=\dfrac{x}{16}[/tex]
On cross multiplication, we get
[tex]4\times 16=x\times x[/tex]
[tex]64=x^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{64}=x[/tex]
[tex]\pm 8=x[/tex]
Since ratio can be negative or positive, therefore, the value of x is either -8 or 8.

Enter a value for x that makes the equation -2x + 10 + 4x = 70 true
Answer:
x = 30
Step-by-step explanation:
- 2x + 10 + 4x = 70, that is
2x + 10 = 70 ( subtract 10 from both sides )
2x = 60 ( divide both sides by 2 )
x = 30

If a circle is cut from a square piece of plywood, as shown in the picture below, how much plywood would be leftover?
Answer:
What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.
Step-by-step explanation:
Formulas:
area of a square: A = bh
area of a circle: A =
square measurements:
b = 28
h = 28
circle measurements:
(≈3.14)
r = 14
A = (28)(28)
A = 784
area of square = 784 in^2
A = 3.14 ()
A = 3.14 (196)
A = 615.44 in^2
784 - 615.44 = 168.56
The amount of plywood left over is 168.56 in^2.
Hope this Helps.

On a map, Roseville and smith town are 5 1/2 inches apart If the actual distance between the town is 16 1/2 miles, to what unit rate is the map drawn
Answer: The unit rate = 3 miles per inch.
Step-by-step explanation:
Given: Distance on map = [tex]5\dfrac12[/tex] inches [tex]=\dfrac{11}{2}[/tex] inches
Actual distance = [tex]16\dfrac12[/tex] miles [tex]=\dfrac{33}{2}[/tex] miles
That means 1 inch on map = [tex]\dfrac{\dfrac{33}{2}}{\dfrac{11}{2}}\ miles[/tex]
[tex]=\dfrac{33}{2}\ miles[/tex]
[tex]=3\ miles[/tex]
Hence, the unit rate = 3 miles per inch.
In a community center 15 bottles are spaced evenly 12 cm apart from each other in a row for competition. What is the distance from the fourth bottles to the tenth bottles
Answer:
72cm
Step-by-step explanation:
From the 4th bottle to the 10th bottle there would be 6 gaps each of 12 cm as mentioned in the question.
Therefore, the total gap or distance between 4th and 10th bottles = 6*12 =
72cm

The area of a rectangular field is 6840 m2. If the width of the field is 72m , what is its length?
Answer:
I believe that the answer is 95 meters.
Explanation:
Okay, so to solve this question, you must know the formula to solve for the area of a rectangle/square.
Area of a rectangle/square - l x w
In this question, you can see the the width (72 m) and the area (6840 m²) is already given. What you can do in this situation is to use the opposite operator (division) to solve for the length of the rectangular field.
6840 ÷ 72 = 95
You can always double check to see if the number is correct.
A = l x w
= 72 m x 95 m
= 6840 m²
Really hope this helped. :)
Given parallelogram JKLM, complete the following statements.
X=
Y=
m
m< L= Degrees
ML=
Answer: x= ?
y= 5
mK= 17
mL= 17
ML= 33
Step-by-step explanation:
i dont want to explain but i don’t know what x is i’m sure the rest are right
The value of x is; 20, the value of the y is 5 and the value of the angle K is; 43 degrees.
Given that;
Length of the line XL is 2y+23.
Length of the line Ml is 32-3y.
Length of the line JK is 6y-13.
What is Parallelogram?Parallelogram is a closed shaped quadrilateral in which the opposite sides are equal and parallel. Consecutive angles in a parallelogram are supplementary.
The sum of the consecutive angles is equal to the 180 degrees (supplementary).
Thus,
m∠M + m∠J = 180°
(6x + 17) + (2x + 3) = 180°
8x + 20 = 180°
8x = 160°
x = 20
So, m∠M = (2x + 3)°
= 2(20) + 3
= 43°
As the opposite sides of the parallelogram are equal. Thus;
(6y - 13) = 32 - 3y
6y + 3y = 32 - 13
9y = 45
y = 5
Now Opposite angles of a parallelogram are equal in measure thus,
m∠M = m∠K = 43°
Thus, the value of x = 20,
the value of the y = 5 and value of the angle K = 43 degrees.
