What are a, b, c and d​

Mathematics
1 answer:
GuDViN [60]2 years ago
7 0

Answer:

Step-by-step explanation:

4 g.

c=42

a=b=d

a+b+42=180

a+a=180-42

2a=138

a=138/2=69

a=69

b=69

c=42

d=69

5a.

a=30

angle O=180-(a+30)=180-(30+30)=180-60=120°

d=80

angle O=180-(d+80))=180-(80+80)=180-160=20°

central angle O of middle triangle=180-(120+20)=180-140=40°

b=c

b+c+40=180

b+b=180-40

2b=140

b=140/2=70

b=70°

c=70°

Johanna is selling cheese at the farmers’ market. One wheel of cheese has a diameter of 9 inches.
AleksAgata [21]

Answer:

The area of the wheel cheese is 63.62 inches²

The cost per square inch is $0.29

Step-by-step explanation:

* Lets explain how to solve the problem

- One wheel of cheese has a diameter of 9 inches

∵ The wheel is shaped a circle

∵ The diameter of the wheel is 9 inches

- The radius of the circle is half its diameter

∵ The radius of the wheel = 1/2 its diameter

∴ The radius of the wheel = 1/2 (9) = 4.5 inches

- The area of a circle = πr²

∴ The area of the wheel cheese = π(4.5)² = 63.61725124 inches²

* The area of the wheel cheese is 63.62 inches²

- The 9-inch wheel of cheese costs $18.60

∵ The area of the wheel cheese is 63.62 inches²

∵ It cost is $18.60

- To find the cost per square inch divide the cost of the wheel

  by its area

∴ The cost per square inch = 18.60 ÷ 63.62 = 0.29

∴ The cost per square inch is $0.29

A company manufactures its product at a cost of $0.50 per item and sells it for $0.85 per item daily overhead is $600 how many i
Nataly_w [17]

so the company has an overhead of $600, usually that involves premises leasing and industrial equipment for the manufacturing of the product, that's cost.  The cost to make each item is 50 cents, so if the company produces "x" items, their cost is 0.5x total.

so our cost equation C(x) = 0.5x + 600   <---- items' cost plus overhead.

the company sells the product for 85 cents, so if they sell "x" items, their total revenue or income will be 0.85x.

so our revenue equation is simply R(x) = 0.85x.

as you already know, the break-even point is when.... well, you break even, no losses but no gains either, how much you take in is the same amount that you shelled out, namely R(x) = C(x).

\bf \stackrel{R(x)}{0.85x}=\stackrel{C(x)}{0.5x+600}\implies 0.35x=600\implies x=\cfrac{600}{0.35} \\\\\\ x\approx 1714.285714285714\implies \stackrel{\textit{rounded up}}{x=1714}

Does (-15, -691) make the equation y = -51x - 74 true?<br><br><br>​
dimulka [17.4K]

Well, we can input both variables to check and see if the numbers hold.

-691 = -51(-15) - 74

-691 = 765-64

-691 = 701

(-15, -691) does not make the equation true.
