At a leather shop 50 jackets were sold in February the shop keeper at the store wants to encourage the sales team to sell more l

Gekata [30.6K]

If 50 jackes have been sold in February and the team will get bonus by selling 30% more jackets in March, then they'll need to sell:

30% * 50 =
= 30/100 * 50 =
= 3/10 * 50 =
= 3 * 5 =
= 15 [more jackets]

So they'll get the bonus after selling 50 + 15 = 65 jackets.

7. A kite in the shape of a square with a diagonal 32 cm and an isosceles triangle of base 8 cm and sides 6 cm each is to be mad

grin007 [14]

Answer:

Step-by-step explanation:

diagonal = 32 cm

Area of square = $\dfrac{d^{2}}{2}$

$=\dfrac{32*32}{2}\\\\=512 \ cm^{2}$

Diagonal separate the square into two equal triangles.

Area of upper triangle that is shaded black = area of lower triangle = 512/2

= 256 cm²

Isosceles triangle:

a = 6 cm ; b = 6 cm c = 8cm

$s = \dfrac{a+b+c}{2}\\\\=\dfrac{6+6+8}{2}\\\\=\dfrac{20}{2}\\\\=10\\\\s-a = 10 - 6 = 4 \ cm\\\\s-b = 10-6 = 4 \ cm\\\\c - c = 10 - 8 = 2 \ cm\\\\Area = \sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{10*4*4*2}\\\\=\sqrt{2 * 2 * 4 * 4 * 5}\\\\=4*2\sqrt{5}\\\\=8\sqrt{5}\\\\=8*2.24\\\\=17.92 \ cm^{2}$

Area of black shade paper = 256 + 17.92 = 273.92 cm²

Area of white shade paper = 256 cm²

Area of the isosceles triangle = s(s-a)(s-b)(s-c)

kvasek [131]

Answer:

254.34

Step-by-step explanation:

You first have to know the formula which is

$c = \pi \: {r}^{2}$

You multiply 9 by 9 which gives you 81.

$c = \pi \times 81$

pi equals 3.14

so 3.14 × 81 = 254.34
