Answer:

$Product = \frac{3}{5}ab$

Step-by-step explanation:

Given

$-\frac{3}{7}a$

$-\frac{21}{15}b$

Required

The product

The product is:

$Product = -\frac{3}{7}a * -\frac{21}{15}b$ '

Cancel out the negative signs

$Product = \frac{3}{7}a * \frac{21}{15}b$

Simplify fractions

$Product = \frac{1}{7}a * \frac{21}{5}b$

$Product = \frac{1}{1}a * \frac{3}{5}b$

$Product = \frac{3}{5}ab$

25% discount for AED 4000

Lostsunrise [7]

Answer:

The 25% discount on AED 4000 will be: 1000 AED

Step-by-step explanation:

Given

The amount = 4000

Discount = 25%

In order to determine a 25% discount on the amount AED 4000, all we need means is to multiply 25/100 or (0.25) by 4000.

i.e

Discount amount = 25% of 4000

= 25/100 × 4000

= 0.25 × 4000

= 1000 AED

Thus, the 25% discount on AED 4000 will be: 1000 AED

The volume of a cone is 1540cm³. If its radius is 7cm, calculate the height of the cone. (Take pi = 22/7)

Ann [662]

Answer:

$h=30$

Step-by-step explanation:

Volume of a cone=1540 $cm^{3}$ , Radius=7cm.

The height of a cone=h

When we need to find the height of a cone, we can use the formula of the volume of a cone, which is $\frac{1}{3} \pi r^{2} h$ to find the height of a cone.

$1540cm^{3} =\frac{1}{3}\pi r^{2} h$

Put the pi value=22/7 and the value of radius which is 7 cm into the formula.

$1540cm^{3}=\frac{1}{3}*\frac{22}{7} 7^{2}h$

$1540cm^{3} =\frac{154}{3}h$

Move $\frac{154}{3}$ to another side. 1540 divided by $\frac{154}{3}$ to calculate what is the value of h, h is the height of a cone. Like this.

$\frac{1540cm^{3} }{\frac{154}{3} } =h$

$30=h$

Rearrange the h.

$h=30$

I hope you will understand my solution and explanation. If you still cannot get the point, you can ask me anytime! Thank you!
