Answer 1
Answer:  Exact length: OP = 6*sqrt(2) centimetersApproximate length: OP = 8.48528 centimeters

====================================================

Explanation:

Check out the diagram below. I recreated the diagram in your textbook, but I added on a few other points and segments.

Point E is the midpoint of segment AB. Segment OE is perpendicular to AB.

Point F is the midpoint of CD. Segment OF is perpendicular to CD.

Right triangle AOE forms with OA = 10 as the hypotenuse (radius of the circle) and AE = 8, since E cuts AB in half.

Use the pythagorean theorem to find that...

a^2+b^2 = c^2

(AE)^2 + (OE)^2 = (OA)^2

8^2 + (OE)^2 = 10^2

64 + (OE)^2 = 100

(OE)^2 = 100-64

(OE)^2 = 36

OE = sqrt(36)

OE = 6

--------------------

Because chord CD is the same length as chord AB, this means the chords are the same distance from the center point O.

So, OE = OF = 6

Since we have rectangle OEPF, the opposite sides are congruent and we can say OF = EP = 6

Now focus on right triangle OEP. Use the pythagorean theorem again

a^2+b^2 = c^2

(OE)^2 + (EP)^2 = (OP)^2

(6)^2 + (6)^2 = (OP)^2

72 = (OP)^2

(OP)^2 = 72

OP = sqrt(72)

OP = sqrt(36*2)

OP = sqrt(36)*sqrt(2)

OP = 6*sqrt(2)

I believe it’s C, 21 divided by 7. This one doesn’t leave any extra mugs out cause 21 divided by 7 is 3, leaving 7 mugs per 3 shelves and having none left.

Both sides minus 3

[tex]7x = 4x + 15 - 3[/tex]

[tex]7x = 4x + 12[/tex]

Both sides minus 4x

[tex]7x - 4x = 12[/tex]

first, group the same variables together.

2x - 2x - 2y - y + 5z + 3z

then, this step which I don't have a name for.

2x - 2x = 0x.

-2y - y = -3y

5z + 3z = 8z

0x - 3y + 8z

2). Bill has twice as many candies as Fred. Tim has 3 fewer than 3 times as many candles as Fred.
In all, they have 177 candies. How many do they each have?

Answers

Step-by-step explanation:

Answer:-

[tex]\tt{Let \ the \ candies \ taken \ by \ Fred \ be \ x.}[/tex]

Now, let's Solve!

So, according to Question,

Bill = 2x

Tim = 3x-3

Total Candies = 177.

[tex]\bf{x+2x+3x-3=177}[/tex]

Totalling x,

[tex]\bf{6x-3=177}[/tex]

[tex]\bf{6x=177+3}[/tex]

[tex]\bf{6x = 180}[/tex]

[tex]\boxed{\sf{x = 30}}[/tex]

So, Fred has 30 candies.

Bill's Candies = 2×30 = 60 Candies

Tim's Candies = 3×30-3 = 90-3 = 87 Candies.

The area of a square ice rink is 400 yd.². What is the perimeter of the rink in yards

Answers

Answer:

80 yd^2

Step-by-step explanation:

Since the formula for squares is s^2, we can use this to set up an equation, which is

s^2=400

If we square root this, we get

s=20

The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

How can you use the graph of a quadratic equation to determine the number of real solutions of the equation?​

Answers

Answer:

Step-by-step explanation:

The number of real solution of a quadratic equation can be found from the number of x-intercepts on the graph. If the curve passes through the x-axis twice, (2 x-intercepts), then the equation has two real solutions.

If it passes through once, (the vertex is on x-axis), then there is one real solution, and if it does not touch the x-axis at all (floating above it or below it), then it has no real solutions.

Hope this helped!

75.6

Step-by-step explanation:

75.64

The 6 is in the tenths place.

Drop all digits to the right of the 6.

A bag with quarters and nickels contains 87 coins.The total amount is $7.35. How many quarter and nickels are in the bag

Answers

Answer: 72 nickels and 15 quarters

Step-by-step explanation:

72 times .05 = 3.6 or $3.60

15 times .25 = $3.75

Total = $7.35

.05 is representing the nickels and .25 is representing the quarters and if you take a calculator and do 87-72 you get 15 and you can set it up yourself to double check. But I wouldn't recommend doing it with pennies that's how I got confused so many times and you can also give yourself a similar problem if you want to make sure you know how to do it. Sorry if this was confusing.
