Answer:

x>-3

Step-by-step explanation:

−3x+6<15

Step 1: Subtract 6 from both sides.

−3x+6−6<15−6

−3x<9

Step 2: Divide both sides by -3.

−3x

−3

x>−3

Answer:

$11 \frac{25}{64}$

<h3>First answer is correct</h3>

Step-by-step explanation:

$2 \frac{1}{4} \times 2 \frac{1}{4} \times 2 \frac{1}{4} \\ \frac{9}{4} \times \frac{9}{4} \times \frac{9}{4} \\ = \frac{729}{64} \\ = 11 \frac{25}{64} \: \: \: {in}^{3}$

Which equation represents the circle described? (in picture)

Sedaia [141]

You are right. In circle equation we have =r² so the correct answer will be C od D. But we have to calculate the center of a circle.

$x^2+y^2-8x-6y+24=0\quad|-24\\\\(x^2-8x)+(y^2-6y)=-24$

Complete the square:

$x^2-8x+a^2\implies a=\dfrac{8x}{2x}=4\implies x^2-8x+4^2\\\\\\y^2-6y+b^2\implies b=\dfrac{6y}{2y}=3\implies y^2-6y+3^2$

And we have:

$(x^2-8x)+(y^2-6y)=-24\\\\(x^2-8x+4^2)-4^2+(y^2-6y+3^2)-3^2=-24\\\\
(x-4)^2+(y-3)^2-16-9=-24\\\\(x-4)^2+(y-3)^2-25=-24\quad|+25\\\\\boxed{(x-4)^2+(y-3)^2=1}$

So the answer is C (the same left side of equation).

A fruit sekker buts 50 boxes of mangoes each containing 100 m mangoes at the rate of ₹1200 per box he sells each mangoes for ₹20

Dahasolnce [82]

Answer:

₹40000, 66.6%

Step-by-step explanation:

Given data

Number of boxes= 50

Cost per box= ₹1200

Total cost= 50*1200= ₹60000

Total number of mangoes in all 50 boxes= 50*100= 5000 mangoes

Cost price per mago= 60000/5000= ₹12

Selling price per mango= ₹20

profit = selling price- cost price

profit= 20-12

proft= ₹8

Total profit = 8*5000

Total profit= ₹40000

%profit = 40000/60000*100

%profit= 0.666*100

%profit= 66.6%
