Answer:
x = 19°, <SOR = 17°
Step-by-step explanation:
(5x + 4) + (x - 2) + (3x + 7) = 180°
Combine like terms:
9x + 9 = 180°
9x = 171
x = 19
<SOR = (19 - 2) = 17°

Step-by-step explanation:
Calculate the approximate area of the shape to the nearest cm2.
This is very simple. So you use two formulas:
Rectangle: Length • Width
Semicircle: Area = [tex]\frac{\pi r^2}{2}[/tex]
With that, you do 0.8 ÷ 2 = 0.4 because we will be using radius. When solved, you get 0.2512... But for this problem, I will be rounding everything to the nearest hundredths.
Area of semicircle: ≈ 0.25
Now we solve for the rectangle. That is very easy. Just multiply 0.75 • 0.8 and you get 0.6
For this problem, I'm not sure why they make you round to the nearest centimeter, but if you do, you get 1 cm. Otherwise,
Round to nearest tenth: 0.9
Round to nearest hundredths: 0.85
The weight of the square is 10 grams
how much heavier is the circle then the triangle
Will be marked BRAINLIEST
Answer:
The circle is 2 times heavier than the triangle.
Step-by-step explanation:
We can see this by identifying the amount of squares there are per shape.
Since there are 3 triangles and 3 circles on each side, we can identify how heavy each one is by comparing them to the squares.
There are 2 squares per triangle and 1 square per circle, so we know that the circles are 2 times heavier than the triangles.
The weight of the circle is 10 grams heavier than the weight of the triangle.
What is the solution to the equation?In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.
The weight of the square is 10 grams. Let 'x' and 'y' be the weight of the triangle and circle. Then the equation is given as,
x + 20 + x + 20 + x + 20 = y + 10 + y + 10 + y + 10
Simplify the expression, then we have
x + 20 + x + 20 + x + 20 = y + 10 + y + 10 + y + 10
3x + 60 = 3y + 30
x + 20 = y + 10
y = x + 10
The weight of the circle is 10 grams heavier than the weight of the triangle.

Can u explain how to get the answer???
Answer:
Since there are 8 sections and 3 are even
We consider that 3/8
We now multiply by 120 since they said 120 times it is spun
3/8 x 120 = 45
The answer is 45.

I think the answer would be high.
Step-by-step explanation:
You can see how the X on the bottom is (13) it's one less than the X on the top. So my reasoning is since there are fewer differences b/w the two sets, there are more vaiables overlapping.

Four runners completed in a 10-kilometer relay race. Each Runner ran the same distance. What was that distance?
Answer:
each runner ran 2.5 kilometers
Step-by-step explanation:
10÷4=2.5
The distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.
What is division?A method of dividing something into equal parts is called division. It produces a fair distribution of resources and is one of the four basic operations in mathematics.
How to solve this problem?Total distance = 10 kilometers
Total number of runners = 4
Since they all covered the same distance,
the distance = 10/4 = 2.5 kilometers
Therefore, the distance would be 2.5 kilometers if four runners completed a 10-kilometer relay race while covering the same distance each.
