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

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

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 bb - 3b = -5 - 1
-2b = -6
b = 3
Find JK
JK = KL = b + 5
JK = b + 5
Plug in the value of bJK = 3 + 5
JK = 8
Therefore, using the property of the sides of a rhombus, the missing length is determined as: B. JK = 8.

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.

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

First you need to find the slope of the two points.
The slope is -2
Then you use the slope intercept form to find the y intercept.
y=2x+b
You then have to plug in the x and y points.

6= -4+b
b=10
Lastly write using the slope intercept
