Your friend shows you a coin collection. In​ it, 48/50 of the coins are quarters. What percent of the coins are​ quarters?

Answers

Answer:

If you take 50 and multiply it by two, you get 100. But, in order to get the right number, you have to multiply 45 by two as well. 45 x 2 is 90. 90 out of 100 is 90 percent. So 90% is the answer

Step-by-step explanation:

Answer:

96% or .96

Step-by-step explanation:

48 divided nu 50 equals .96 which then equals to 96 percent.

Answer:

y = x + 1

Step-by-step explanation:

I HOPE IM NOT TOO LATE BUT basically first u use the points to find the slope:

[tex]\frac{3+1}{2+2} = \frac{4}{4} = 1[/tex]

so far then, u have y = x + b  (there's an invisible 1 in front of the x)

next, substitute in the values from one set of coordinates to solve for b. I picked the second one bc positive numbers are easier:

y = x + b

3 = 2 + b

3 - 2 = b

1 = b

put this into your equation, and u get y = x + 1

3x+2y=21
-2y -2y
3x= -2y+2y
•then divide both sides by 3
3x/3 = -2y+21/3

Answer:

  59.8 cm

Step-by-step explanation:

The length of arc ABC is ...

  s = rθ

  s = (9 cm)(220/180π) = 11π cm ≈ 34.558 cm

The length of segment CD is 9 cm less than the length of segment OD. OD can be found using the law of sines.

  OD/sin(A) = AD/sin(O)

  OD = AD·sin(A)/sin(O) = (21 cm)sin(24°)/sin(140°) ≈ 13.288 cm

Then the length of CD is ...

  CD = OD -9 cm = (13.288 cm) -(9 cm) = 4.288 cm

The perimeter is the sum of the segment and arc lengths:

  P = ABC + CD +AD

  P = 34.558 cm + 4.288 cm + 21 cm = 59.846 cm

The perimeter of the shape is about 59.8 cm.

Wo groups are hiking at about the same speed. Mario's group hikes for 2.5 hours. Seema's group hikes for 4.7 hours and covers 8.8 more miles. How fast are the hikers going? Solve the equation below to find out. 4.7x = 2.5x + 8.8

Answers

Answer:

x = 4 miles per hour

Step-by-step explanation:

4.7x = 2.5x + 8.8

Collecting like terms

4.7x - 2.5x = 8.8

2.2x = 8.8

x = 8.8 / 2.2

x = 4 miles per hour

This ellipse is centered at the origin. Find it’s equation. Verticles: (0,-6) (0,6) Foci: (0,-2) (0,2)

Answers

The equation of the ellipse will be x² / 36 – y² / 32 = 1.

What is an ellipse?

An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.

This ellipse is centered at the origin.

Vertices: (0,-6) (0,6)

Foci: (0,-2) (0,2)

Then the equation of the ellipse will be  given as

x² / a² – y² / b² = 1

Let c be the distance between the origin to foci.

Then we have

c = 2

And the value of a will be

a = 6

Then the value of a² will be

a² = 6² = 36

The value of b is the distance from center to one of the Co-vertices. Then the value of b² will be

a² – b² = c²

36 – b² = 2²

        b² = 36 – 4

        b² = 32

Then the equation of the ellipse will be x² / 36 – y² / 32 = 1.
