Answer:
1.5 cm.
Step-by-step explanation:
If 1 cm = 30 km, then half a cm equals 15 km.
We need to find 45 km. We know that 1 cm = 30km and half a cm = 15 km. Adding both of these together, we can get 1.5cm = 45km.
A cyclist travels 15 miles in 45 minutes.
What is his average speed in mph?
The answer is 20 Km/hr
first : you have miles . then change it into Km .
second: 45 min to sec
finally speed is the distance per unit time
Find the value of x.

Answer:
x = 70
Step-by-step explanation:
180* (n-2)
180*(6-2)
180*(4) = 720
102 + 146 + 120 + 124 + 158 = 650
720 - 650 = 70
A polygon is a planar figure characterized by a limited number of straight-line segments. The value of the x is 70°.
What is a polygon?A polygon is a planar figure characterized by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
The sum of the interior angles of a n-sided polygon is calculated using the formula,
Sum of the interior angles = (n-2) × 180°
For the given polygon, the number of sides is equal to 6. Therefore, the sum of the interior angles of the polygon is,
Sum of the interior angles = (6-2) × 180°
= 4 × 180°
= 720°
Further, the sum of the interior angles for the given polygon can be written as,
Sum of the interior angles = 102° + 146° + 120° + 124° + 158° + x°
720° = 102° + 146° + 120° + 124° + 158° + x°
x = 720° - (102° + 146° + 120° + 124° + 158°)
x = 720° - 650°
x = 70°
Hence, the value of the x is 70°.

Do 4x and 15+x have the same value when x is 5?
Are 4x and 15+x equivalent expressions? Explain your reasoning.
Answer:
1. yes 2. no
Step-by-step explanation:
Hi there!
When x is equal to 5, 4x and 15+x have the same value because 4*5= 20 and 15+5 = 20.
4x and 15+x are not equivalent expressions because they cannot be simplified to create the same expression nor will they produce the same answer every time.

Answer:
[tex]a)\ x_1=-3i,\ x_2 =3i[/tex]
[tex]b)\ x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]
Step-by-step explanation:
Given equations:
[tex]a)\ x^2+19=10\\\\b)\ 4x^2+3=43[/tex]
A. x² + 19 = 10
Step 1: Subtract 19 from both sides.
[tex]\\\implies x^2+19-19=10-19\\\\\implies x^2=-9[/tex]
Imaginary number rule: For any positive real number "k", [tex]\sqrt{-k} = i\sqrt{k}[/tex]
Note: Two imaginary (complex) solutions indicate that the graph will not intersect the x-axis. As a result, it has no real roots.
Step 2: Take the square root of both sides (positive and negative roots).
[tex]\\\implies \sqrt{x^2}=\sqrt{-9}\\\\\implies x=\pm\ i\sqrt{9}\\\\\implies x=\pm\ 3i[/tex]
Step 3: Separate the solutions.
[tex]\implies x_1=-3i,\ x_2 =3i[/tex]
----------------------------------------------------------------------------------------------------------------
B. 4x² + 3 = 43
Step 1: Subtract 43 from both sides.
[tex]\\\implies 4x^2++3-3=43-3\\\\\implies 4x^2=40[/tex]
Step 2: Divide both sides by 4.
[tex]\\\implies 4x^2=40\\\\\implies \dfrac{4x^2}4=\dfrac{40}{4}\\\\\implies x^2=10[/tex]
Step 3: Take the square root of both sides (positive and negative roots).
[tex]\\\implies \sqrt{x^2}=\sqrt{10}\\\\\implies x=\pm\ \sqrt{10}[/tex]
Step 4: Separate the solutions.
[tex]\implies x_1=-\sqrt{10},\ x_2=\sqrt{10}[/tex]

Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)
Answer:
An exponential function in the form y=9(4ˣ)
Step-by-step explanation:
Step(i):-
Given that exponential function
y = a bˣ ...(i)
The equation (i) passes through the point (0,9)
9 = a (b )⁰ = a
a =9
Step(ii):-
The equation (i) passes through the point (3,576)
576 = 9(b)³
⇒ [tex]\frac{576}{9} = b^{3}[/tex]
⇒ 64 = b³
⇒ 4³ = b³
[tex](4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }[/tex]
b = 4
Final answer:-
An exponential function in the form y=abˣ
An exponential function in the form y=9(4ˣ)

2x+3y=34
3x+2y=36
solve for x and y
Answer:
(8, 6 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 34 → (1)
3x + 2y = 36 → (2)
Multiplying (1) by 3 and (2) by - 2, then adding will eliminate the x- term
6x + 9y = 102 → (3)
- 6x - 4y = - 72 → (4)
Add (3) and (4) term by term to eliminate x, that is
5y = 30 ( divide both sides by 5 )
y = 6
Substitute y = 6 into either of the 2 equations and solve for y
Substituting into (1)
2x + 3(6) = 34
2x + 18 = 34 ( subtract 18 from both sides )
2x = 16 ( divide both sides by 2 )
x = 8
solution is (8, 6 )
