Answer:

  2. chord theorem; t = 10.5

  3. chord theorem; x = 5

Step-by-step explanation:

For both of these problems, the relevant theorem is the "intersecting chord theorem", also referred to as the "chord theorem." It tells you the product of the lengths of the parts of one chord is equal to the product of the lengths of the parts of the other chord.

2. 20t = 10·21

  t = 210/20 . . . . divide by 20

  t = 10.5 . . . . . . . simplify

__

3. 10(x +4) = 15(x +1)

  10x +40 = 15x +15 . . . . . eliminate parentheses

  25 = 5x . . . . . . . . . . . . . subtract 10x+15

  5 = x . . . . . . . divide by 5

39,000 over 12 = ?? Also, show your work so I can do the rest of these myself

Answers

Answer:

3,250

Step-by-step explanation:

Let's go from left to right, using multiple of 12 times a power of 10 in the process.

What is the closest multiple of 12,000 (12 * 10^3) to 39,000 without going over? That's 3 (36,000). That's the thousands digit in this answer.

12,000 * 3 = 36000

39000 - 36000 = 3000

What's the closest multiple of 1,200 (12 * 10^2) to 3,000 without going over? That's 2 (2,400). That's the hundreds digit.

1,200 * 2 = 2,400

3,000 - 2,400 = 600

What is the multiple of 120 (12 * 10) closest to 600 without going over? That's 5 (600, it's even!). That's the tens digit. Since it goes evenly, 0 is the ones digit.

120 * 5 = 600

600 - 600 = 0.

The answer to 39,000 over 12 is 3,250.

JKLM is a rhombus. Find JK. PLZ HELP!

Answers

Answer:

JK=8

Step-by-step explanation:

the sides are equal so set KL equal to LM

b+5=3b-1

b=6=3b

6=2b

b=3

b+5

3+5

8

Using the property of the sides of a rhombus, the missing length is determined as: B. JK = 8.

What is a Rhombus?A rhombus is a quadrilateral.The four sides of a rhombus are congruent, that is, they have equal measure.

Thus:

KL = ML

Substitute

b + 5 = 3b - 1

Solve for b

b - 3b = -5 - 1

-2b = -6

b = 3

Find JK

JK = KL = b + 5

JK = b + 5

Plug in the value of b

JK = 3 + 5

JK = 8

Therefore, using the property of the sides of a rhombus, the missing length is determined as: B. JK = 8.

The shed in Stephanie’s back yard has a door that measures 6 feet high and 3 feet wide. Stephanie would like to buy and store a ladder in the shed diagonally. What is the maximum height, in feet, of a ladder she can buy to fit through the door?

Answers

Answer:

the answer is 6 ft hope it helps

The maximum height, in feet, of a ladder she can buy to fit through the door is, 6.7 feet

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

We have to given that;

The shed in Stephanie’s back yard has a door that measures 6 feet high and 3 feet wide.

Now, By using Pythagoras theorem;

The length of a ladder she can buy to fit through the door is, x

⇒ x² = 6² + 3²

⇒ x² = 36 + 9

⇒ x² = 45

⇒ x = √ 45

⇒ x = 6.7 feet

Thus, The maximum height, in feet, of a ladder she can buy to fit through the door is, 6.7 feet

Raul calculated that he would spend $125 on school supplies this year. He actually spent $87.50 on school supplies. What is Raul’s percent of error?

A 42.9%

Answer:

C 30%

Step-by-step explanation:

87.50/125= 0.70

1-0.7-0.3

Answer:

42.9%

Step-by-step explanation:

So you would use [ ((V2 - V1) / |V1|) * 100 ]

V1 = 87.5 to V2 = 125

= ((125 - 87.5) / |87.5|) * 100

= (37.5 / 87.5) * 100

= 0.428571 * 100

= 42.8571% change

= 42.8571% increase

Then you round to 42.9!

A cylinder has a volume of 198 cm3, and its base has an area of 22 cm2. What is the height of the cylinder? V= πr²h

Answers

Answer:

The height of cylinder is 9 cm

Step-by-step explanation:

Volume of cylinder = 198 cm³

Base Area = 22 cm²

We need to find height of the cylinder

The formula used is: [tex]Volume\:of\:cylinder=\pi r^2h[/tex]

Where [tex]Base\: Area = \pi r^2[/tex]

First we need to find radius r

[tex]Base\: Area = \pi r^2\\22=3.14\: r^2\\r^2=\frac{22}{3.14}\\r^2=7\\Taking\: square\: root\: on\: both\: sides\\\sqrt{r^2}=\sqrt{7}\\r=2.656[/tex]

So, we get radius r = 2.656

Putting values of volume and radius are to find height

[tex]Volume\:of\:cylinder=\pi r^2h\\198=3.14(2.656)^2h\\h=\frac{198}{22}\\h=9[/tex]

So, the height of cylinder is 9 cm
