Answer:
fewest to most:
0.000000009 ⇒ 0.0450 ⇒ 321.598 ⇒ 1.0000001
Step-by-step explanation:
0.000000009 = 1 sig fig
0.0450 = 3 sig figs
321.598 = 6 sig figs

Answer: b =50°
Step-by-step explanation:
The angles on a straight line =180°
180° = 50°+90°+b
180°-50°-90°=b
50° = b
Answer:
Step-by-step explanation:
∠b + ∠a + 50° = 180°
∠b + ∠90 + 50° = 180°
∠b = 180° - 90° - 50° = 40°

Aregular hexagon is dilated by a scale factor of 0.4 to create a new hexagon. The perimeter of the new hexagon is 0.4 times the perimeter of
the original hexagon
O True
False
Answer:
True.
Step-by-step explanation:
It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.
It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.
For example,
Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32
Let's find image using scale factor 0.4, we get
length =0.4(12)= 4.8
width =0.4(4)=1.6
So, perimeter of image = 4.8+4.8+1.6+1.6=12.8
If we compare the perimeters
0.4(32)=12.8.
So, it is true.

what is the value of x in simplest radical form?
Answer:
13
Step-by-step explanation:
here's your solution
=> base = 12
=> perpendicular = 5
=> we need to find hypotenuse = ?
=> we know , h^2 = p^2 + b^2
=> h^2 = 12^2 + 5^2
=> h^2 = 144 + 25
=> h^2 = 169
=> h= √169
=> h= 13

Of 42 cities, 5 have a lake and 29 have a river running through them what fraction of these 42 cities have a lake or river running through them
Answer: 17/21
Step-by-step explanation:
Number of cities = 42
Fraction of cities that has lake = 5/42
Fraction of cities that have rivers = 29/42
The fraction of these 42 cities that have a lake or river running through them will then be:
= 5/42 + 29/42
= 34/42
= 17/21

The equation that matches this diagram is
3(y + 200) = 3000.
What is the value of Y.
Answer: y = 800
Step-by-step explanation:
3(y + 200) = 3000
3y + 3(200) = 3000
3y + 600 = 3000
3y = 2400 [Subtract 600 from both side]
y = 800 [Divide 3 in both side to solve for y]
Complete the square of x^2-2x+17
Answer:
(x - 1)² + 16
Step-by-step explanation:
x² - 2x + 17 = 0Subtract 17 from both sides of the equation.
x² - 2x = -17Use the formula (b/2)² to see which number you have to add to both sides.
(-2/2)² = 1Add 1 to both sides of the equation.
x² - 2x + 1 = -17 + 1Factor the left side of the equation into a perfect square.
(x - 1)² = -16Add 16 to both sides of the equation.
(x - 1)² + 16(x - 1)² + 16 is the equation in standard form (x² - 2x + 17) rewritten by completing the square.

Simplify the sum. State any restrictions on the variables.
X-2/x+3 + 10x/(x^2)-9
Please show all work and don’t forget the restrictions!
The resulting expression will be [tex]\frac{x+2}{x-3}\\[/tex]
How to simplify fractional sumGiven the expression as shown in the question:
[tex]\frac{x-2}{x+3} + \frac{10x}{x^2-9}[/tex]
Find the LCM of the expression to have:
[tex]\frac{(x-2)(x-3)+10x}{(x+3)(x-3)}[/tex]
Expand the expression
[tex]\frac{(x^2 - 5x+6+10x}{(x+3)(x-3)}\\\frac {x^2 + 5x+6}{(x+3)(x-3)}\\[/tex]
Expand the expression
[tex]=\frac {x^2 + 2x + 3x +6}{(x+3)(x-3)}\\=\frac {x(x + 2) + 3(x +2)}{(x+3)(x-3)}\\=\frac{(x+2)(x+3)}{(x+3)(x-3)}\\ =\frac{x+2}{x-3}\\[/tex]
Hence the resulting expression will be [tex]\frac{x+2}{x-3}\\[/tex]

david and jason have marbles in a ratio of 2:3. together they have a total of 35 marbles . how many marbles dose David have
Answer:
14 marble
Step-by-step explanation:
here's your solution
=> Total number of marble = 35
=> ratio of David and Jason = 2 : 3
=> let the ratio be in x
=> now, 2x + 3x = 35
=> 5x = 35
=> x = 35/5
=> x = 7
=> number of marble with David = 7*2 = 14
=> number of marble with Jason = 7*3 = 21
hope it helps
Answer:
number of marbles that David had=
[tex]35 \times \frac{2}{5} \\ 14marbles[/tex]
