Answer:

18 and 52

Step-by-step explanation:

x + Y = 70

X - Y= 34 find the value of X interms of Y to find the answer:

X - Y= 34

X = 34 +Y

x + Y = 70

(34 + Y ) + Y = 70

34 + Y +Y = 70

2Y =70-34

2Y/2=36/2

Y = 18

x + 18 = 70

x=70 - 18

x= 52

check:

18 + 52= 70

52 - 18= 34

A tepee is designed to have a diameter of 10 ft and a volume of 393 ft. At

Citrus2011 [14]

Answer:

15 ft.

Step-by-step explanation:

The tepee is a cone and its volume

= 1/3 pi r^2 h where r = radius and h = height.

The radius r = 1/2 * 10 = 5 ft.

So we have the equation:

393 = 1/3*3.14* 5^2 * h

h = 393 / (1/3*3.14*25)

= 15.02 ft.

Ronald is making hats and scarves for charity. He has enough yarn to make 5 hats and 8 scarves. Takes him 12 hrs to knit a hat,

kari74 [83]

Constraints are simply the subjects of an objective function.

The inequality that represents the constraint is: $12x + 6y \le 20$

Represent the number of hats with x, and the number of scarves with y.

From the question, we have:

He spends 12 hours to knit a hat
He spends 6 hours to knit a scarf

So, the equation of the total time spent is:

$Time = 12x + 6y$

This time spent is not more than 20 hours.

So, the inequality is

$12x + 6y \le 20$

Hence, the inequality that represents the constraint is: $12x + 6y \le 20$
