Answer:
1000 seconds
Step-by-step explanation:
You can start by finding the unit rate for each of them to lay down a tile. That is, how many tiles they can lay down in one second. Ralph can lay one down in 1/5 of a second, while Bob takes 1/4. 1/5+1/4=4/20+5/20=9/20 of a tile per second. Dividing 450 by 9/20, you get 1000 seconds. Hope this helps!

Answer:
C 720`
Step-by-step explanation:
The sum of the interior angles of the hexagon is S = 720°
What is the sum of the interior angles of a polygon?The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the sum of the interior angles of a hexagon be S
Let the polygon be represented as a hexagon
Now , the number of sides of a hexagon is n = 6
So , sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
On simplifying , we get
nθ = S = 180 ( 6 - 2 )
S = 180 x 4
S = 720°
Therefore , the value of S is 720°
Hence , the sum of the interior angles of hexagon is 720°

Answer:
6 units by 12 unitsStep-by-step explanation:
Since the measurements in meters are multiples of 4, it makes this problem a little easier.
First you divide 8 by 4 to get 2
Then divide 16 by 4 to get 4
After that you're going to multiply 3 units by both quotients separately.
So you multiply 3 by 2 to get 6
Then you multiply 3 by 4 to get 12
So then you end up with a 6 unit by 12 unit drawing.
therefore, the answer is
6 units by 12 unitsformula of area of a semicircle

THE FUNCTION IS ALWAYS INCREASING.
Complete question: The graph of f(x)= power of 3√x + 8 is shown.
Step-by-step explanation:
See attachment for the missing graph.
when x = -16 ; y = -2
when x = -12 ; y = -1.5
when x = -8 ; y = 0
when x = -6 ; y = 1.25
when x = 0 ; y = 2
when x = 6 ; y = 2.5
As the value of x increases, so does the value of y. Thus, the function is always increasing.

Suppose that a storm front is traveling at 33 mph. When the storm is 13 miles away a storm chasing van starts pursuing an average speed of 54 mph. How long does it take for the van to catch up with the storm? How far have they driven? (Hint: we can let our two variables be x= distance and t= time. Additionally, [speed x time= distance]. Won’t the van catch up when the distances are equal?
Answer:
= 15mins 18 seconds. The storm chaser van drove 13.53 miles to catch up with the storm which obviously has moved less than 0.53 miles as it was same time but multiplied below by 0.5 per minute as speed per minute is 0.5 for the storm. See right at the end the storm only moved 1.11 mile.
Step-by-step explanation:
We count in 1 minutes
54 mph = 54/60 = 0.9 miles per minute
Storm = 13 m + 1 minute is;
33/60 = 0.55 miles = 11/20
M = (16 7/10 * 9/10x) = ( 3 7/10 * 11/20y ) +13
M = 15 3/10x = ( 407/200y +13) (407/200 = y starting value +13)
M = 15 3/10x = 15 3/10 = 16 7/10x (the same as 16 7/10* 9/10 for x)
M = 15 3/10 x = 15 3/10 = 15.03
M = 16 7/10x / 9/10y (is also the same as 186/1000)
X = 185⁄1000 = 37⁄200xy x 16 7/10 (as starting value)
7/10 of 60 = 42 minutes
3/10 of 60 = 18 minutes
x = 15 mins 18 seconds.
y = 15 mins 18 seconds.
as 0.005 left over for y 3/10 was actually 15.035 gives us 0.005 of 60 can not be rounded up to a second.
However as we started with 16mins and 7/10 we can see that we multiplied by 9/10 so when we divide 16 7/10 by 9/10 we find 185⁄1000 = 37⁄200
To equal the mileage of the storm of where we multiplied 3 7/10 by 17/10
= 37/200 just the same
We added 13 miles of the storm to find each was multiplied by the larger x sum 9/10 and y was multiplied
As 35/200 + 13 =
13 37/200
37/200 of 60 = 11.1 = 11.06 minutes which is
= 15.04 % more for y as 13 + 2 mins + 06 seconds = 15.06 = 15.035
The percentage looks the same but valued different as 2 of 13 as a percentage is multiplied as 13 x 15.04% to equal the 2 of 15 miles as 15.04%.
To find how many miles we go back and see 15.035 = 15 7/200
Then we multiply this by 0.9 miles for the storm van
= 15 7/200 x 0.9 = 13.5315 = 13.53 miles
For the storm itself we can prove 0.53 increase of mileage
417/200 x 0.53 = 1.10505 = 1.11 miles. rounded up

2(6x+9−3x)=5x+21 PLEASE HELP !!
Answer:
x=3
Step-by-step explanation:
Simplifying
2(6x + 9 + -3x) = 5x + 21
Reorder the terms:
2(9 + 6x + -3x) = 5x + 21
Combine like terms: 6x + -3x = 3x
2(9 + 3x) = 5x + 21
(9 * 2 + 3x * 2) = 5x + 21
(18 + 6x) = 5x + 21
Reorder the terms:
18 + 6x = 21 + 5x
Solving
18 + 6x = 21 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
18 + 6x + -5x = 21 + 5x + -5x
Combine like terms: 6x + -5x = 1x
18 + 1x = 21 + 5x + -5x
Combine like terms: 5x + -5x = 0
18 + 1x = 21 + 0
18 + 1x = 21
Add '-18' to each side of the equation.
18 + -18 + 1x = 21 + -18
Combine like terms: 18 + -18 = 0
0 + 1x = 21 + -18
1x = 21 + -18
Combine like terms: 21 + -18 = 3
1x = 3
Divide each side by '1'.
x = 3
Answer:
x=3
Step-by-step explanation:
(12x+18-6x)=5x+21
6x+18=5x+21

Since they're congruent triangles according to the given.
help me write an expression to find perimeter.
Answer:
Perimeter, [tex]P=\dfrac{2}{5}(5x+14)[/tex]
Step-by-step explanation:
We have, a hand woven rectangular rug measures x ft long and [tex]2\dfrac{4}{5}\ ft[/tex] wide. For a rectangular shaped object, perimeter is equal to the sum of all sides. If l is length and b is width, then
Perimeter, [tex]P=2(l+b)[/tex]
We have, l = x ft and b = [tex]2\dfrac{4}{5}\ ft=\dfrac{14}{5}\ ft[/tex]
So,
[tex]P=2(x+\dfrac{14}{5})[/tex]
or
[tex]P=\dfrac{2}{5}(5x+14)[/tex]

Answer:
C!
Step-by-step explanation:
It appears that all choices have the 1st part the same, so we are looking at domains. I recommend drawing the functions without the domain limitations. We know that the linear function is closed so it's inequality is either [tex]\geq[/tex] or [tex]\leq[/tex]. So eliminate B and D. Since the quadratic function continues to the left the inequality sign should be <. So the answer is C

Write an equation of a circle whose center is (-5,4) and whose diameter is 12
Answer:
(x + 5)² + (y - 4)² = 36
Step-by-step explanation:
The equation of a circle in standard form id
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 5, 4) and r = 12 ÷ 2 = 6 , thus
(x - (- 5))² + (y - 4)² = 6², that is
(x + 5)² + (y - 4)² = 36

Good luck on your assignment....
Answer:
x = 9
Step-by-step explanation:
→You can use the Pythagorean Theorem to solve:
[tex]a^2+b^2=c^2[/tex]
→The "a," and "b," are the legs, and the "c," is the hypotenuse. In this case, we are already given the hypotenuse as 41, and we are trying to find a leg:
[tex]40^2+b^2=41^2[/tex]
[tex]1600+b^2 = 1681[/tex]
→Subtract 1600 from both sides:
[tex]b^2=81[/tex]
→To get "b," by itself, square root both sides, like so:
[tex]\sqrt{b^2} =\sqrt{81}[/tex]
→81 is a perfect square meaning it has two factors that are identical.
[tex]b = 9[/tex]
Factor 2x^2-7x-15.
