What is the value of x
1 answer:
Answer:
98
Step-by-step explanation:
There are 7 sides to this polygon. Forget all the lettering on the figure. Concentrate on the number of triangles you can count. There are 5 of them. Each one has 180 degrees. So the total number of degrees on the interior of the figure is
5 * 180 = 900
All you have to do is add up all the angles including the x and equate them to 900
x + 146 + 122 +142+ 140 + 110 + 142 = 900 Collect the terms on the left.
x + 802 = 900 Subtract 802 from both sides
x = 900 - 802
x = 98

Answer:
A. 1206 cm³
Step-by-step explanation:
We have a cone and are asked to find the approximate volume of it.
Keep in mind we are using π for 3.14
The forumla of a cone is V = πr²
We know the radius = 12
and the height = 8
Substitute :
V = π12²
Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:
V =
Cancel the common factor - 3 :
V =
Multiply 8 and 3π :
V =
Solve the exponent :
V =
Multiply :
V =
Multiply for the final answer :
1205.76 cm³
which can be rounded up to
A. 1206 cm³
Answer:
-4
Step-by-step explanation:
The function is linear; therefore, the slope of the line joining any two points is the same.
We take any two points from the table and compute the slope or rise/ run between them— let is take points (-4, -2) and (-2, -10).
The slope of the line joining the points is
The slope of the function is -4.
