Find the ratio of length to breadth of the rectangle with length 80cm & breadth 32cm.

gtnhenbr [62]

The length of the rectangle equals 80 cm, and the width equals 32 cm.

Divide the length to the width, we get the ratio between them :

80 : 32

Now, we simplify by dividing them both by the same number, in this case it's 16

=> 80 : 32 = (80 : 16) : (32 : 16) = 5:2

So, the ratio between the length and the width is 5:2

Suppose that you want to mix two coffees in order to obtain 100 pounds of a blend. If x represents the number of pounds of coffe

Fantom [35]

Answer:

The required expression that represents the number of pound of coffees B is $100-x$

Step-by-step explanation:

Consider the provided information.

You want to mix two coffees in order to obtain 100 pounds of a blend.

Let x represents the number of pounds of coffee A and y represents the number of pounds of coffee B.

The obtained weight is 100 pounds.

$x+y=100$

$y=100-x$

Hence, the required expression that represents the number of pound of coffees B is $100-x$

The quadratic function f(x)=ax^2+4x+c has a maximum at the point (1, 9) . What are the values of a and c?

valina [46]

Answer: a = -2 and c = 7

Step-by-step explanation:

(this answer uses some basic calculus)

We know that $f'(x) = 2ax + 4$ , and since $(1,9)$ is a maximum of $f$ , then $f'(1) = 0$ . That means $2a + 4 = 0$ , so $\boxed{a = -2}$ . Then since $f(1) = 9$ , we have $-2(1)^2 + 4(1) + c = 9$ , so $\boxed{c = 7}$ .
