Answer:
585 miles
Step-by-step explanation:
divide 715 by 11 so that you can see the mph (miles per hour). Then multiply that number by 9 for the amount of miles he would travel in nine hours
715/11=65
65x9=585

Need help ASAP please and thank you
how do i solve this
Answer:
64
Step-by-step explanation:
Okay, here it goes:
Where there is a g you insert -2 and where there is an h you insert 5
(2(-2)+9(5)-5)-(6(-2)-4(5)+2)
If two numbers are side-by-side with no other sign between them, you multiply
(-4+45-5)-(6(-2)-4(5)+2)
(-4+45-5)-(-12-20+4)
There is a subtraction sign between these equations. That means you must distribute the negative sign to the equation on the right.
Remember:
Negative × Negative = PositiveNegative × Positive = NegativePositive × Positive = Positive-4+45-5+12+20-4
Now just add them together. I recommend going left to right.
-4+45=41
41-5=36
36+12=48
48+20=68
68-4=64
You have a 3L jug and a 5L jug. You need to fill the 5L jug with exactly 4L of water. Write an algorithm to solve this problem. I will award Brainliest!
Fill the 3L jug, then pour its contents into the 5L jug.
Fill the 3L jug again, then pour as much of it (2L) as you can into the 5L jug.
Now the 5L jug is full, and the 3L jug is carrying 1L of water.
Empty the 5L jug.
Pour the 1L of water from the 3L jug to the 5L jug.
Finally, fill up the 3L jug, then transfer its water into the 5L jug. It now has 4L of water.

¿ Cuál es la ecuación de la circunferencia que pasa por punto (-4,2) y
su diámetro es 8 ?
Porfaaaa
Answer:
(x+4)² + (y-k) ² = 16
Step-by-step explanation:
The equation of the circumference is expressed as;
(x-h) ² + (y-k) ² = r²
(h,k) is the centre
r is the radius
Given that diameter = 8
radius = 8/2
radius = 4units
Given that h = -4 and k = 2
(x-h) ² + (y-k) ² = r²
(x-(-4)) ² + (y-2) ² = 4²
(x+4)² + (y-k) ² = 16
This gives the required equation

The surface area of a cube is S(x) = 6x?, where x is the length of the side of each edge of a cube, Restrict the domain to create a one-to-one
function. Find and describe the inverse function.
Answer:
Restrict values of x to . Then the surface area function is one-to-one and has an inverse.
Write y instead of S(x). Interchange x and y, then solve for y.
This function could be used to find the edge of a cube with a given surface area. For example, if the area is x = 54, then the edge is

Consider the functions f(x) = 2x + 10
Which statement is true?
Answer:
B
Step-by-step explanation:
It is linear and increasing.
If it is linear, it is increasing at a constant rate with a straight line.
Exponential means it is a curved line and would have an equation like f(x)=5^x
If it was decreasing, it would have a negative slope, such as -2x +10

Answer:
a= 45
Step-by-step explanation:
all angles equal 180 degrees so you take the angle given which is 45 and the other which is a right angle, or 90 degrees and subtract 45 from 90 and you get 45 so a = 45 and you add up 45 + 45 + 90 thats 180!

A swimming pool has a diameter of 24 feet. What is the minimum amount of fabric needed to cover the pool if the cover must hang off by 1 foot all around the pool?
Answer:
531.167 ft²
Step-by-step explanation:
Given data
Dimension of pool
Diameter =24ft
Radius =12ft
If the cover must hang by 1ft around, then the diameter is 26ft
Radius =13ft
Area of cover = πr²
Substitute
Area = 3.142*13²
Area =3.143*169
Area =531.167 ft²
Hence the minimum area is 531.167 ft²
How do I find the answer?

Put the quadratic into vertex form and state the coordinates of the vertex. y= y= \,\,x^2-6x-3 x 2 −6x−3
Answer:
[tex]y = (x - 3)^2 - 12[/tex]
[tex](3,-12)[/tex]
Step-by-step explanation:
Given
[tex]y = x^2 - 6x - 3[/tex]
Solving (a): In vertex form
The vertex form of an equation is:
[tex]y = a(x - h)^2 + k[/tex]
To do this, we make use of completing the square method.
We have:
[tex]y = x^2 - 6x - 3[/tex]
------------------------------------------------------------------
Take the coefficient of x (i.e. -6)
Divide by 2; -6/2 = -3
Square it: (-3)^2 = 9
Add and subtract the result to the equation
------------------------------------------------------------------
[tex]y = x^2 - 6x - 3[/tex]
[tex]y = x^2 - 6x + 9 - 9 - 3[/tex]
[tex]y = x^2 - 6x + 9 - 12[/tex]
Factorize [tex]x^2 - 6x + 9[/tex]
[tex]y = x^2 - 3x-3x + 9 - 12[/tex]
[tex]y = x(x - 3)-3(x - 3) - 12[/tex]
Factor out x - 3
[tex]y = (x - 3)(x - 3) - 12[/tex]
Express as squares
[tex]y = (x - 3)^2 - 12[/tex]
Hence, the vertex form of [tex]y = x^2 - 6x - 3[/tex] is: [tex]y = (x - 3)^2 - 12[/tex]
Solving (b): State the coordinates of the vertex.
In [tex]y = a(x - h)^2 + k[/tex]; the vertex is: (h,k)
The vertex of [tex]y = (x - 3)^2 - 12[/tex] will be [tex](3,-12)[/tex]
12- 1/5r = 2r + 1
R=??
Answer:
r = 5
Step-by-step explanation:
12 - 1/5r = 2r + 1
12 - 0.2r = 2r + 1
12 - 0.2r + 0.2r = 2r + 0.2r + 1
12 = 2.2r + 1
12 - 1 = 2.2r + 1 - 1
2.2r = 11
2.2r ÷ 2.2 = 11 ÷ 2.2
r = 5
Answer:
r = 5
Step-by-step explanation:
12- 1/5r = 2r + 1
12 = 11/5r + 1
5(11) = (11/5r)5
55 = 11r
r = 5
