Slav-nsk [51]

Answer:

64 carnations and 16 roses.

Step-by-step explanation:

The events committee buys 80 flowers

The flowers are a combination of carnations and roses.

Each carnation costs $0.50 and each rose costs $2.50

The committee spends a total of $72

<u>Solution:</u>

<u />

Let there be (c) carnations and (r) roses.

So,

c + r = 80 flowers

and $0.50c + $2.50 = $72

This forms a simultaneous equation:

c + r = 80 ... (i)

0.5c + 2.5r = 72 ... (ii)

Multiplying equation (i) by 0.5 and equation (ii) by 1 gives;

0.5c + 0.5r = 40 ... (i)

0.5c + 2.5r = 72 ... (ii)

Subtracting (i) from (ii) gives;

0c + 2r = 32

2r = 32

r = 32 ÷ 2 = 16

Therefore, there are 16 roses

and 80 - 16 = 64 carnations

How do you solve: cos(x-π/3)=-1

gladu [14]

Answer:

x = $\frac{4\pi }{3}$

Step-by-step explanation:

given

cos(x - $\frac{\pi }{3}$ ) = - 1, then

x - $\frac{\pi }{3}$ = $cos^{-1}$ (- 1) = π

Add $\frac{\pi }{3}$ to both sides, hence

x = π + $\frac{\pi }{3}$ = $\frac{4\pi }{3}$

Math help please show work thanks

Answer:

600.4 cm^2

Step-by-step explanation:

first we should find the base of samller triangle

hypotenuse = 35 cm

one side = 30 cm whereas other has be be find

using pythagoras theorem

a^2 + b^2 = c^2

30^2 + b^2 = 35^2

900 + b^2 = 1225

b^2 = 1225 - 900

b^2 = 325

b = $\sqrt{325}$

b = $5\sqrt{13}$

area of big triangle

base = 22 + $5\sqrt{13}$

area of a triangle = base * height / 2

= 30 (22 + $5\sqrt{13}$ ) /2

=30*22 + 30* $5\sqrt{13}$ / 2

=660 + 540.83 / 2

=1200.83 / 2

=600.415

=600.4 cm^2
