Find the ratio of 300ml to 6l

Answers

Answer 1
Answer: 1:20 because 1=1000ml
6x1000ml=6000
300/6000=20
So the final answer is 1:20

B. x = 1
C. all real numbers except x = 1
D. all real numbers

Answers

2(x + 7) - 1 > 15                 3(x + 2) < 2x + 7
2x + 14 - 1 > 15                  3x + 6 < 2x + 7
2x + 13 > 15                       3x - 2x < 7 - 6
2x > 15 - 13                        x < 1
2x > 2
x > 2/2
x > 1

so, x > 1 OR x < 1.....all real numbers except 1

Step-by-step explanation:

What plus what equals 11 and what times what equals 30

Answers

The numbers that add up to 11 and multiply to 30 are 5 and 6

How to determine the numbers

From the question, we have the following parameters that can be used in our computation:

Multiply = 30

Addition = 11

Let the numbers be x and y

So, we have

xy = 30

x + y = 11

Let x be 5 and y be 6

So, we have

5 * 6 = 30

5 + 6 = 11

Hence, the numbers are 5 and 6

A projectile is fired straight upward with an initial velocity of 400 feet per second. The height of the projectile, h(t), if represented by the function h(t)=-16t^2+400t, where t is the time in seconds. How long does it take the projectile to reach the maximum height?

Answers

Taking into account the definition of maximum, minimum and vertex of a quadratic function, it takes 12.5 seconds for the projectile to reach maximum height.

A quadratic function is defined in the form:

y= f (x) = ax² + bx + c

Every quadratic function has a maximum or a minimum, which is the vertex of the parabola. If the parabola has an upward concavity, the vertex corresponds to a minimum of the function; whereas if the parabola has concavity downwards, the vertex will be a maximum.

That is, if the coefficient a is positive the parabola is concave and the vertex will be a minimum of the function, while if a is negative the parabola will be convex and the vertex is a maximum.

The maximum or minimum is reached in xv=(-b)/(2a)  

The maximum or minimum value of y is obtained by evaluating the function at xv, this is, f (xv).

In this case, the function is:

h(t)= -16t² + 400t

where t is the time in seconds

Being a = -16 and b = 400, the value of a is negative, so the vertex will be the maximum.

You want to know the time it takes for the projectile to reach the maximum height, that is, the maximum in t. That is, you must calculate t using the expression: t=(-b)/(2a)

So: t=(-400)/(2x(-16))

Solving:

t=(-400)/(-32)

t= 12.5 seconds

It takes 12.5 seconds for the projectile to reach maximum height.

Answer:

You can find the answer by using the formula x=-b/2a

Step-by-step explanation:

Remember the maximum height will be at the vertex. The x value of the vertex is your time, so use x=-b/2a. Then if it had also asked what the height was, you would plug that answer into your equation to find the y value of the vertex. Pretty sure your teacher is just asking you to find the x though:)

9. Find the diagonal of a square with perimeter 28 meters.

Answers

Answer:

diagonal of square = d = 9.899

Step-by-step explanation:

let side of square = x

diagonal of square = d

perimeter = P = 28

4 * x = P

x = 28/7

x = 7

By using Pythagorean theorem we get

x^2 + x^2 = d^2

7^2 + 7^2 = d^2

d^2 = 98

d = sqrt(98)

diagonal of square = d = 9.899
