answer:
m/s --- km/h = [tex]\frac{1000}{3600}[/tex]
km/h= [tex]\frac{5}{18}[/tex]
6m/s= [tex]\frac{6*5}{18}[/tex]
6m/s= 1.66 km/h
The speed of the bicycle in km/h is 21.6 km/h.
Given that;
A bicycle has a speed of 6 m/s.
Since we know that;
1 km = 1000 m
And, 1 hour = 3600 s
Hence change the speed of the bicycle in km/h as;
[tex]Speed = 6 m/s[/tex]
It can be equal to;
[tex]Speed = \dfrac{6 \times \dfrac{1}{1000} km }{\dfrac{1}{3600} seconds }[/tex]
[tex]Speed = 21.6 km/s[/tex]
Therefore, the speed of the bicycle in km/h is 21.6 km/h.

Please Help, solve this create and solve system of equations and solve for x and y
Answer:
x = 4, y = 12
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral sum to 180° , then
25x - 2 + 7y - 2 = 180
25x + 7y - 4 = 180 ( add 4 to both sides )
25x + 7y = 184 → (1)
--------------------------
22x + 7 + 7y + 1 = 180
22x + 7y + 8 = 180 ( subtract 8 from both sides )
22x + 7y = 172 → (2)
Subtract (2) from (1) term by term to eliminate y
3x + 0 = 12
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
25(4) + 7y = 184
100 + 7y = 184
7y = 84 ( divide both sides by 7 )
y = 12

Step-by-step explanation:
Answer:
x=-14
Step-by-step explanation:
Expand 8(3x+6)
a=8 b=3x c=6
=8*3x+8*6
Simplify; 8*3x+8*6

24x+48=18x-36
Subtract 48 from both sides;
24x+48-48=18x-36-48
Simplify;
24x=18x-84
Subtract 18x from both sides;
24x-18x=18x-84-18x

A number decreased by 9 is 12. Which equation represents this situation?
Answer:
x - 9 = 12
Step-by-step explanation:
We can use x as "a number"
So the equation so far is just "a number", or x.
Decreased by 9 can also be said as subtracted by 9, so that makes the equation x - 9.
"is 12" can also be said as equals 12, which makes the equation x - 9 = 12
Answer:
_ - 9 = 12
Step-by-step explanation:
You can identify the starting number by adding 9 and 12 together to get 21. The completed equation would be 21 - 9 = 12.

Answer:
122
Step-by-step explanation:
The first thing to notice is that <EBC and <ABE form a straight line. This means they are a linear pair, also known as complementary. So, when they are added together they will equal 180 degrees. Therefore, to solve, set up and solve the algebraic equation, 180=58+x. When 58 is subtracted from both sides, you are left with x=122.

Answer:
x³ + 11x² + 18x
Step-by-step explanation:
(x² + 2x)(x + 9)
Step 1: Distribute x²+2x into x + 9.
x³ + 2x² + 9x² + 18x
Step 2: Combine like terms.
x³ + 11x² + 18x
The area of this rectangle is x³ + 11x² + 18x.
Answer:
Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x
Step-by-step explanation:
The height is (x + 9) and the width is (x^2 + 2x) and the the area of the rectangle is equal to: Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x

Evaluate without a calculator:
cot -270°
Answer:
0
Step-by-step explanation:
The cotangent function is defined as cot x = adj / opp.
The terminal side of 270 degrees is the lower half of the y-axis. The adj side is zero (0) and the opp side is -1;
Therefore, cot (-270 degrees) = adj / opp = 0/(-1) = 0
The required answer is cot(-270°) is undefined
Given that cot(-270°).
To evaluate cot(-270°) without a calculator, use the trigonometric properties and definitions.
First, let's recall the definition of the cotangent function. The cotangent of an angle is defined as the ratio of the adjacent side to the opposite side in a right triangle.
cot(theta) = adjacent side / perpendicular
When we consider -θ, it represents a reflection or rotation of θ about the origin. This reflection does not affect the ratio of the adjacent side to the opposite side in a right triangle.
Thus, cot(-θ) = cot(θ).
In this case, dealing with an angle of -270°. Since angles can be measured counterclockwise, -270° represents a rotation of 270° clockwise from the positive x-axis.
At -270°, the terminal side of the angle lies on the negative y-axis.
cot(-270°) = cot(270°)
Since 360° - 270° equals 90°, cot(360° - 270°) = cot (90°)
At 90°, the terminal side of the angle lies on the positive y-axis.
In a right triangle formed with the terminal side of the angle, the adjacent side and the opposite side are both zero.
Since the cotangent is the ratio of the adjacent side to the opposite side, and both sides are zero in this case, the cotangent of -270° is undefined or "not defined."
Therefore, cot(-270°) is undefined.

What is a rectangular prism?A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.
The figure below is a net for a right rectangular prism.
Then the surface area of the rectangular prism will be
Surface area = 2(LW + WH + HL)
Surface area = 2(7 × 8 + 8 × 14 + 14 × 7)

Mrs. Delgado purchased notebooks at 2 for $5 and pens
at $2 per package. She spent $19 for a total of 8 items.
How many notebooks and pens did she buy?
Answer:
Mrs. Delgado purchased 6 notebooks and 2 packages of pens.
Step-by-step explanation:
Given that Mrs. Delgado purchased notebooks at 2 for $ 5 and pens at $ 2 per package, and she spent $ 19 for a total of 8 items, to determine how many notebooks and pens did she buy the following calculation must be performed:
5/2 = 2.5
8 x 2.5 + 0 x 2 = 20
6 x 2.5 + 2 x 2 = 19
Therefore, Mrs. Delgado purchased 6 notebooks and 2 packages of pens.
