Answer:
150 degrees
Step-by-step explanation:
Let's start off by looking at what we are working with in this specific problem:
We can see that we are looking at 2 angles, angle L and angle M, that add up to a total of 180 degrees (aka a straight line)
Now that we know that, we also have to keep is mind that angle L + angle M = 180 degrees.
Now that we've got all of that out of the way, let's set up a simple algebraic equation:
angle L + angle M = 180
We also know that angle L is 30 degrees so let's add it into the equation we have just created:
30 + angle M = 180
We now know that 30 plus angle M (whatever it might be) is equal to 180 so in order to solve this problem we have to do some simple subtraction.
180 - 30 = angle M
Now we are left with:
150 degrees = angle M
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!
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

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.
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

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

What is the equation of the circle with a radius of 5 and center of (2, 3)?
A (x + 2)2 + (y + 3) = 25
B (x + 2)2 + (y + 3)2 = 5
OA
OB.
Answer:
None of the above.
Step-by-step explanation:
The equation should be (x - 2)^2 + (y - 3)^2 = 25
The standard equation of a circle is:
(x - a)^2 + (y - b)^2 = r^2
where (a,b) are the coordinates of the center and r, the radius.
here the center = (2,3) hence a = 2 , b = 3 and r = 5

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
