notsponge [240]

Answer:

The volume of the pyramid is $1,260\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the triangular pyramid is equal to

$V=\frac{1}{3}BH$

where

B is the area of the triangular base

H is the height of the pyramid

step 1

Find the area of the base B

$B=\frac{1}{2}bh$

we have

$b=14\ cm$

$h=18\ cm$

substitute

$B=\frac{1}{2}(14)(18)=126\ cm^{2}$

step 2

Find the volume

we have

$B=126\ cm^{2}$

$H=30\ cm$

substitute

$V=\frac{1}{3}BH$

$V=\frac{1}{3}(126)(30)=1,260\ cm^{3}$

guapka [62]

First apply 20% discount then applied $15 coupon combination gives better deal.

As given in the question,

Let final cost of the shoes be $100

First apply $15 coupon then applied 20% discount

100-15=$85

Now, 20% of 85= (20/100) × 85

=$17

Final price, 85 - 17 =$68

First apply 20% discount then applied $15 coupon

Now, 20% of 100= (20/100) × 100

=$20

100-20 = $80

Apply coupon $15

Final price, 80 - 15 =$65

Therefore, first apply 20% discount then applied $15 coupon combination gives better deal.
