Determine if line AB is tangent to the circle.
Answer:
Is a tangent
Step-by-step explanation:
~ By definition, a tangent to circle is a straight line, presently perpendicular to a radius if one. In this case tangent AB should be perpendicular to the radius. If we were to call the center O, we would say AB should be perpendicular to OA. ~
1. Now let us say at the moment that AB is a tangent. If that is so, it should be that m∠A = 90 degrees ( ° ), provided AB is ⊥ to OA by definition.
2. Now the triangle ABO is a right triangle, and with that is should be that Pythagorean Theorem is applied. This can help us prove if AB is a tangent or not. If Pythagorean Theorem is not applicable it would mean ABO is not a right angle triangle, that AB is not ⊥ to OA, and thus can't be a tangent.
3. Let us say x ⇒ side OA, and that side BO = 9 + 8 + 17:
AB^2 + OA^2 = BO^2,
15^2 + x^2 = 17^2,
x = 8
4. Now there are two radii present, OA is only one of them. As radii are ≅, OA = other radii, 8 = 8
5. This proves that Pythagorean Theorem is applicable, that ABO is a right triangle, that m∠A = 90°, and that by definition AB is a tangent

how many times smaller is the surface area of a cube if the side length is multiplied 1/2
Answer:
1/4, or 4 times smaller
Step-by-step explanation:
Since the surface area of a cube is just the combination of the area of all of the square sides, and the formula for those is s^2, if the side length was decreased by 1/2 then the surface area would decrease by (1/2)^2=1/4. Hope this helps!
A prism with a square base has a volume of 96 ft3. The height of the unit is 6 feet. A prism has a length of l, width of 2, and height of 6 feet. Given what you know about the figure, complete these sentences. The area of the square base is feet2. The length of the prism is feet. The width of the prism is feet.
Answer:
The area of the square base is 16 feet the length of the prism is 4 feet, and the width of the prism is 4 feet.
Step-by-step explanation:
The length of the prism is L = 4 feet
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
A square base has a volume of 96 ft3 and a height of 6 feet. Since the volume of a prism is given by the product of the area of the base and the height, we can find the area of the square base as follows:
Volume = area of base x height
96 = area of base x 6
Area of base = 16 ft²
Now, we are given a prism with length of l, width of 2, and height of 6 feet. Since the base is a square, we can set l equal to the width and solve for it using the area of the base we found earlier:
Area of base = l²
16 = l²
l = 4 feet
Hence , the length of the prism is 4 feet and the width is 2 feet

ABCD is a square with sides of length 9cm. How many points (inside or outside the square) are equidistant from B and from C, and are exactly 6cm from A?
Answer: one point only.
Step-by-step explanation:
Since the length of the sides of the square is 9 cm, taking a point outside the square which is equidistant from point B and C will never give exact 6 cm from A.
The only way to achieve this is by taking a equidistant point inside.
You can achieve exactly 6 cm from point A from point between B and C
But can only achieve a single point if it has to be equidistant from point B and C.

You can use Pythagoras theorem as it is a right angle
a^2 + b^2 = c^2
where 'c' is the hypotenuse
Rearrange this to find a side length
c^2 - a^2 = b^2
where 'b' is the missing length
10^2 - 8^2 = b^2
100 - 64 = b^2
b^2 = 36
Square root this to get the answer
b = 6cm

Use the spinner to find the theoretical probability of the event. Type your answer in box below in simplified fraction form.
a. Spinning red ___________
b. Spinning a 1 __________
c. Spinning an odd number ___________
d.Spinning a 9 _____________
Answer:
A.) 1/3
B.) 1/6
C.) 1/2
D.) 0
Step-by-step explanation:
Total number of faces on spinner = 6
Probability = (required outcome / Total possible outcomes)
A)
P(spinning Red):
n(Red) / n(total)
n(red) = 2, n(total) = 6
P(spinning red) = 2/6 = 1/3
B.)Spinning a 1 :
n(1) = 1
Therefore, P(spinning 1) = 1/6
C.) spinning an odd number :
Odd numbers = 1,3,5
P(spinning an odd number) = 3/6 = 1/2
D.) spinning a 9:
9 isn't a number on the wheel
P(spinning a 9) = 0/6 = 0
What is the answer to this question? Write an expression in simplest form for the perimeter of a right triangle with leg lengths of 3a to the third power and 4a to the third power.
Answer:
Step-by-step explanation:
Since the length of both legs of the right angle triangle are given, we would determine the hypotenuse, h by applying Pythagoras theorem which is expressed as
Hypotenuse² = one leg² + other leg²
Therefore,
h² = (3a)³ + (4a)³
h² = 27a³ + 64a³
h² = 91a³
Taking square root of both sides,
h = √91a³
The formula for determining the perimeter of a triangle is expressed as
Perimeter = a + b + c
a, b and c are the side length of the triangle. Therefore, the expression for the perimeter of the right angle triangle is
√91a³ + (3a)³ + (4a)³
= √91a³ + 91a³
Candice won the lottery for 30000 dollars.However 20% of her money has to go to the state for taxes.How much money will she receive after paying taxes?
Answer:
She will receive $24,000 after paying taxes
Step-by-step explanation:
This question can be solved using a rule of three.
20% of her money has to go to the state for taxes. So she will receive 100-20 = 80%. $30000 is 100% = 1. How much is 80% = 0.8?
$30000 - 1
$x - 0.8
x = 30000*0.8
x = 24000
She will receive $24,000 after paying taxes

4. The area of the rectangle shown is 200 square units. Find the value of x.
1 point
Your answer
Answer: x = 40
Step-by-step explanation:
Here is the complete question:
The area of the rectangle shown is 200 square units. Find the value of x. Width: 8 Length: 1/2x+5
The area of a rectangle is length multiplied by the width.
Area = Length × Width
Area = 200
Width = 8
Length = 200/8 = 25
Since length is 25 and it has bee denoted as 1/2x + 5. This will be:
1/2x + 5 = 25
1/2x = 25 - 5
1/2x = 20
x = 20 × 2
x = 40
Check:
= 1/2x + 5
= (1/2 × 40) + 5
= 20 + 5
= 25

Get a common denominator of 6
1/2 * 3/3 = 3/6
3/6 + 4/6 = 7/6
We change back to a mixed number
1 1/6
Answer:
7/6 or 1 1/6
Step-by-step explanation:
In this case, you're adding 1/2 plus 4/6.
One strategy you can use to solve this problem is by getting the common denominator.
1/2 is equal to 3/6.
Then you could add 3/6 to 4/6 and you'll get 7/6.
Now depending on the teacher they might want you to have an improper fraction or mixed number.
You can get this mixed number by dividing 7/6 which equals 1 1/6.

You have been tracking how much you spend on gas every month for several months and found that on average you spend about $60 per month. If you had to guess, what would you expect the IQR (Interquartile Range) of your gas spending to be? Would $1, $5 or $100 be most logical? Give statistical reasoning to back up your answer.
Answer: $5
Step-by-step explanation: The interquartile range (IQR) refers to the difference between the upper(75%) quartile and lower(25%) quartile of a distribution. Hence, ensuring that the middle 50% is being captured. With the average given as $60, having a interquartile range capturing the middle 50% as $1 seems so small from a statistical stand point. Similarly, an interquartile range of $100 capturing the middle 50% is also too large and nearly impossible if the average price is $60. However, a price of $5 sit well in between considering the average price of $60
