Answer:
A scale factor exists because any two circles are similar. You can use the radii to determine the scale factor.
Step-by-step explanation:
The ratio between the radii is 31 so the scale factor is 31=3. The circumference of the smaller circle is C=2π(1)=2π.

Answer:
13.7
Step-by-step explanation:
It forms a triangle.
They are trying to find the height, cause they say the east-bound car went east so that makes the bottom of the triangle, the width. They also give is the distance in between both cars so that's the hypotenuse so let's set up the equation...
15² - 6² = 189
now we square root it

Answer:
x = 9cm
using sine rule
a/sine(A) = b/sine(B)
a= x; A= 64° ( alternating angles)
b= 10 cm ; B = 90°
x/sine(64) = 10/sine(90)
x= {10 × sin(64)}/ sin 90

Step-by-step explanation:
At the aquarium, posters of sharks cost $2 and posters of jellyfish cost $6. Mr. Benson spent $64 to buy 12 posters. How many of each type of poster did Mr. Benson buy?
Answer:
8
Step-by-step explanation:
Step 1: Add the cost of the posters together
Shark: 1 = $2
Jellyfish: 1 = $6
2 + 6 = 8
Step 2: Divide the result by the total amount Mr. Benson spent
64 ÷ 8
[tex]= \frac{64}{8}[/tex]
[tex]= 8[/tex]
Therefore, Mr. Benson bought 8 of each type of poster.

A rope is stretched from the top of a
7-foot tent pole to a point on the ground
12 ft from the base of the pole. How long
is the rope ?
Answer:
Step-by-step explanation:
we know two sides of a triangle, one side is 7 feet, the other is 12 feet , so use Pythagoras theorem
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]
[tex]C^{2}[/tex] = [tex]7^{2}[/tex] + [tex]12^{2}[/tex]
[tex]C^{2}[/tex] = 49 + 144
[tex]C^{2}[/tex] = 193
C = [tex]\sqrt{193}[/tex]
C = 13.89 feet
Answer:
The square of the hypotenuse equals the square of the sum of the other two sides.
13.89ft
Step-by-step explanation:
Definition Of Pythagoras Theorem :The Pythagorean theorem states that the total of the squares on a right triangle's legs equals the square on the hypotenuse (the side opposite the right angle)—or, in popular algebraic form, a2 + b2 = c2.
Given:Height of the Tent Pole = 7ft.
Base of the Pole of the Tent = 12ft.
Now we will use Pythagoras theorem to find how long the rope is.
Use of Pythagoras theorem
[tex]\begin{aligned}&C^{2}=A^{2}+B^{2} \\&C^{2}=7^{2}+12^{2} \\&C^{2}=49+144 \\&C^{2}=193 \\&C=\sqrt{193} \\&C=13.89 \text { feet }\end{aligned}[/tex]Hence, the length of the rope is 13.89ft.

3x + 5 = 2x -17
Solve it and show the work because i need to show the work
Answer:
x = -22
Step-by-step explanation:
Subtract 5 from both sides
3x + 5 (-5) = 2x - 17 (-5)
3x = 2x - 17
Subtract 2x from both sides
3x (-2x) = 2x (-2) -22
x = -22

Jessica made 6 19/20 cups of punch. Her punch had two different types of juices in it. If the lunch had 4 1/5 cups of one type of juice, how many cups of the other type of juice did it have?
Answer:
2 3/4 cups
Step-by-step explanation:
Jessica made 6 19/20 cups of punch. Her punch had two different types of juices in it. If the lunch had 4 1/5 cups of one type of juice, how many cups of the other type of juice did it have?
We solve this question using the Subtraction operation
Total cups = cups of first type of juice + cup of other type of juice
6 19/20 = 4 1/5 cups + x
x = 6 19/20 - 4 1/5 cups
Lowest Common Denominator = 20
x = 6 - 4 + (19/20 - 1/5)
x = 2 + (19 - 4/20)
x = 2 15/20 cups
x = 2 3/4 cups
Other type of juice had 2 3/4 cups of juice

A certain television is advertised as a 54-inch TV (the diagonal length). If the width of the TV is 40 inches, how tall is the TV? Round to the nearest tenth of an inch.
Answer:
36.3
Step-by-step explanation:
I tried using the Pythagorean Theorem to measure the length (tallness) of the TV.
[tex]a^2 + b^2 = c^2[/tex]
[tex]a^2 + (40)^2 = (54)^2[/tex]
[tex]a^2 + 1600 = 2916[/tex]
[tex]a^2 = 2916-1600 = 1316[/tex]
[tex]a = \sqrt{1316}[/tex]
[tex]a = 36.27671429[/tex]
When this is rounded up to the nearest tenth, it would go up to 36.3.
So, the length (tallness) of the TV would be 36.3 inches.

Y=-3x-14
-2x-y=9
Answer:
The value of x is -5 and y is 1
Step-by-step explanation:
Here,
y = -3x - 14
-2x - y = 9
Substitution Method
y = -3x - 14 ...(1)
-2x - y = 9 ...(2)
Now, substitute the value of y = -3x - 14 in equation (2) we get,
-2x - y = 9
-2x - (-3x - 14) = 9
-2x + 3x + 14 = 9
x = 9 - 14
x = -5
Now, put the value of x in equation (1) we get,
y = -3x - 14
y = -3(-5) - 14
y = 15 - 14
y = 1
Thus, The value of x is -5 and y is 1
FOR VERIFICATION ONLY:y = -3x - 14
1 = -3(-5) - 14
1 = 15 - 14
1 = 1
-2x - y = 9
-2(-5) - 1 = 9
10 - 1 = 9
9 = 9
Hence, L.H.S = R.H.S

In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. Of a = 7 miles and b = 3 miles, what is the perimeter? If necessary, round to the nearest tenth.
Answer:
17.6 miles.
Step-by-step explanation:
Use Pythagoreans Theorem to find c.
a^2+b^2=c^2
49 + 9 = c^2
58 =c^2
√58=c
7.6=c
Now add all of your sides together to find the perimeter.
7 + 3 + 7.6 = 17.6 miles.
The perimeter of the triangle is 17.6 units.
What is the Pythagorean theorem?The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.
Using the Pythagorean theorem, we can find the length of the hypotenuse c:
c² = a² + b²
c² = 7² + 3²
c² = 58
c = √58 ≈ 7.6 miles
The perimeter is the sum of the three sides:
Perimeter = a + b + c
Perimeter = 7 + 3 + 7.6
Perimeter ≈ 17.6 miles
