Answers

Answer 1
Answer:

For serving 8 peoples, 4 pounds of beef is needed.

What is a linear function? What is a mathematical function, equation and expression?

  • function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
  • expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • equation : A mathematical equation is used to equate two expressions.

Given is that a recipe for stew calls for 2 pounds of beef to serve 4 people. Gina wants to serve 8 people.

It is given that it requires 2 pounds of beef to serve 4 people.

For 1 people, it will take (2/4) or 1/2 pounds of beef.

So, for serving 8 peoples, (1/2) x 8 or 4 pounds of beef is needed.

Therefore, for serving 8 peoples, 4 pounds of beef is needed.

Answer:

h = b = 866.025 m or 866.03 rounded

Step-by-step explanation:

Sides:

a = 1000 m

b = 866.025 m

c = 500 m

Angles:

A = 90 °

B = 60 °

C = 30 °

Other:

P = 2366.03 m

s = 1183.01 m

K = 216506 m²

r = 183.013 m

R = 500 m

Agenda: A = angle A

B = angle B

C = angle C

a = side a

b = side b

c = side c

P = perimeter

s = semi-perimeter

K = area

r = radius of inscribed circle

R = radius of circumscribed circle

Find the constant of variation k for inverse variation. Then write an equation for the inverse variation. y= 5 when x = 7.5 k = 37.5;y = 37.5/x k = 15;xy = 1.5 k = 2.5;y = 2.5/x k = 37.5;y=37.5x

Answers

direct variation has this formula: y = kx
inverse variation has this formula: y = k/x

y = 5 ; x = 7.5 ; k = 37.5

y = k/x ⇒ 5 = 37.5 / 7.5 ⇒ y = 37.5/x

Answer:k=37.5 ; xy=37.5

For the system of equations shown below2x = −y + 6
−4x + 3y = 8
What is the solution to the system of equations?

Answers

2x=-y+6
-4x+3y=8
Rewriting the equations;
y+2x=6
3y-4x=8

Multiplying equation I by 3;
3y+6x=18
3y-4x=8
Subtracting equation II from equation I;
10x=10
x=1

Replacing for x in the first equation;
2x=-y+6
2(1)=-y+6
2=-y+6
2-6=-y
-4=-y
y=4
