A rectangular swimming pool is 19 m wide by 35 m long. what is the length of the diagonal of the pool round to the nearest 10th
Answer:
39.8
Step-by-step explanation:
for this question, use the Pythagorean theorem which is:
a^2 + b^2 = c^3
a = 35
b = 19
c = the answer
lets solve it:
35^2 +19^2 = c^2
solve the exponents first
1225 + 361 = c^2
1586 = c^2
square root both to find c
(the answer is rounded)
39.824 = c
rounded to nearest 10th:
c = 39.8
Answer:
the answer is 39.8m
Step-by-step explanation:
You divide the pool with the diagonal and you obtain a right angled triangle with its base as 35m and its height as 19m. then using pythagoras theorem, you find the length of the hypotenuse and this is the length of the diagonal of the pool.
y+3 7/15 =12 14/15 − 8/15
Solve the equation.
Answer:
y=9 7/15
Step-by-step explanation:
y + 3 7/15 = 12 14/15 - 8/15
y + 3 7/15 = 12 14/15
y + 3 7/15 = 12 14/15
- 3 7/15 - 3 7/15
y = 9 7/15

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]
15 POINTS!!!ASAP!!!HELP!!!!!! I WILl MARK THE BRANLIEST!!!The graph relates the number of gallons of white paint to the number of gallons of red paint Jess used to make the perfect print. Write an equation that describes the relationship.
Answer:
y = 2/3x
Step-by-step explanation:
The first step is to find the slope
Pick two points on the line (0,0) and (3,2)
m = (y2-y1)/(x2-x1)
= (2-0)/(3-0)
= 2/3
The y intercept is 0
Using the slope intercept form
y =mx+b where m is the slope and b is the y intercept
y = 2/3 x +0
y = 2/3x
Answer:
1/3x

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 unitsFind the surface area of the cylinder. Round your answer to the nearest tenth. Diameter: 6 Height: 12

Answer:
She wronged in V1.
Step-by-step explanation:
She write wrongly for the values of length and height. The length of V1 should be 7ft + 4ft which is 11ft and the height is 5ft.
So the volume of V1 is :
V1 = 2ft × 11ft × 5ft
= 110 ft³
Which of these tables represents a function?
Answer:
The answer would be B
Step-by-step explanation:
x-1=y
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

Answer:

Step-by-step explanation:
Use the system of equations to answer the question.
2x + 3y = 8
x-y=5
Answer:
x = 23/5
y = -2/5
Step-by-step explanation:
We are given two equations
2x + 3y = 8 eq. 1
x - y = 5 eq. 2
From eq. 2
x - y = 5
x = 5 + y eq. 3
Substitute eq. 3 into eq. 1
2x + 3y = 8 eq. 1
2(5 + y) + 3y = 8
Simplify the equation
10 + 2y + 3y = 8
10 + 5y = 8
5y = 8 - 10
5y = -2
y = -2/5
or
y = -0.4
Substitute the value of y into eq. 3 to get the value of x
x = 5 + y eq. 3
x = 5 - 2/5
x = 23/5
or
x = 4.6
Therefore, the solution set is
(x, y) = (23/5, -2/5)
This is the point of intersection where these two equations meet.

Answer:
28
Step-by-step explanation:
Consider the expansion:
[tex]$(x+y)^2=\sum_{k=0}^{n} \binom{n}{k}y^{n-k}x^k$$[/tex]
[tex]$ \binom{n}{k}=\frac{n!}{(n-k)!k!}[/tex]
We have
[tex]$\left(x + y\right)^{8}=\sum_{k=0}^{8} \binom{8}{k} \left(y\right)^{8-k} \left(x\right)^k[/tex]
I'm sorry but I will not write and solve everything, typing LaTeX takes time. But that's the idea:
For [tex]k=0[/tex]
[tex]$\binom{8}{0} \left(y\right)^{8-0} \left(x\right)^{0}=\frac{8!}{(8-0)! 0!}\left(y\right)^{8} \left(x\right)^{0}=y^{8}[/tex]
For [tex]k=2[/tex]
[tex]$\binom{8}{2} \left(y\right)^{8-2} \left(x\right)^{2}=\frac{8!}{(8-2)! 2!}\left(y\right)^{6} \left(x\right)^{2}=28 x^{2} y^{6}[/tex]

You are starving after class and go to the kitchen to make a sandwich. You look in the refrigerator and you see you have white bread, rye bread and whole wheat bread, as well as turkey and ham lunch meat, and Swiss cheese, American cheese and Cheddar cheese. How many different possible sandwich combinations can you make
A)16
B)12
C)36
D)18
Step-by-step explanation:
Assuming we use only one kind of bread, meat and cheese, we have 3, 2, and 3 options for them respectively. Therefore, the total amount of sandwiches we can make is 3 * 2 * 3 = 18.

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
