(b)

3\div \frac{2}{3}=\dfrac{3}{\frac{2}{3}}=\frac{3\times3}{2}=\frac{9}{2}

(c)

6 \frac{3}{4}\div 2\frac{1}{4}=\dfrac{\frac{6\times4+3}{4}}{\frac{2\times4+1}{4}}\\\Rightarrow \dfrac{\frac{27}{4}}{\frac{9}{4}}=\frac{27}{9}=3

(d)

Find the value of x in the triangle shown below.
DIA [1.3K]

Answer:

x=8

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2 + x^2 = 10^2

36 + x^2 = 100

Subtract 36 from each side

36-36 +x^2 = 100-36

x^2 = 64

Take the square root of each side

sqrt(x^2) = sqrt(64)

x = 8

g100num [7]

Answer:

Bag 2

Step-by-step explanation:

Given

Bag 1:

14\ ounce = 3.50

Bag 2:

24\ ounce = 5.28

Required

Which is a better buy

To get which buy is better, we first get the unit price of each bag.

Unit\ Price = Amount/Size

For bag 1:

Unit\ Price = 3.50/14

Unit\ Price = 0.25

For bag 2:

Unit\ Price = 5.28/24

Unit\ Price = 0.22

The best buy is the one with smaller unit price

Hence, bag 2 is better to buy
