the ratio of length and breadth of a piece of land is 5:3 and its breadth is 48m. find the perimeter and area of the land.

Marizza181 [45]

Answer:

256 m and 3840 m²

Step-by-step explanation:

The 3 part of the ratio represents 48 m , then

48m ÷ 3 = 16 m ← value of 1 part of the ratio, so

5 parts = 5 × 16 m = 80 m

Then breadth = 48 m and length = 80 m

perimeter = 2l + 2b = 2(80) + 2(48) = 160 + 96 = 256 m

area = lb = 80 × 48 = 3840 m²

if n is a positive integer, for what values of n is the function f(x) =x to the power of n a) even b) odd

Otrada [13]

$f(x)=x^n;\ n\in\mathbb{Z^+}\\\\
function\ is\ even\ when\ f(-x)=f(x)\\\\function\ is\ odd\ when\ f(-x)=-f(x)\\\\a)\ f(x)\ is\ even\ when\ n\ is\ even:f(-x)=(-x)^n=x^n=f(x)\\\\b)\ f(x)\ is\ odd\ when\ n\ is\ odd:f(-x)=(-x)^n=-x^n=-f(x)$

The cake recepi calls for 3 cups of sugar to every 2 cups of flour. if i use 9 cups of sugar how many cups of flour will i need?

scZoUnD [109]

Answer: 6cups of flour

Step-by-step explanation:

3cups of sugar to 2cups of flour

9cups of sugar to xcups of flour

Let sugar rep s

Flour rep f

So we have;

3s=2f

9s= xf

Cross multiply

3s×xf=2f×9s

Xf=2f×9s/3s

Xf=6f

Therefore, 9cups of sugar will be to 6cups of flour
