Answer:
9:6, 12:8, and 15:10 are all ratios equivalent to 3:2
Step-by-step explanation:
To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero).
I love math. Well the formula is y=mx+b. the slope is m so the answer is 7
9x < -27 or 4x > 36
9 9 4 4
x < -3 x > 9
x ∈ (-∞, 3) or (9, ∞)
Answer:
Part A) Is a square
Part B) Is a rectangle
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The figure show a rectangular prism with a square base
Part A) A cross section formed by a plane that intersects the prism parallel to its base would take the shape of a
we know that
A cross section is the intersection of a figure in three-dimensional space with a plane
A plane parallel to the base of a rectangular prism will intersect a cross section that is the same shape as its bases.
so
The cross section is a square
Part B) A cross section formed by a plane that intersects the prism perpendicular to its base would take the shape of a
we know that
A plane perpendicular to the base of a rectangular prism will intersect a cross section that is the same shape as its lateral faces
so
The cross section is a rectangle
Answer:
a. Linear pair theorem
b. x = 40
Step-by-step explanation:
a. You can use linear pair theorem. That is, two angles on a straight line are supplementary. They sum up to 180°
b. Thus:
x + (4x - 20) = 180°
x + 4x - 20 = 180
5x - 20 = 180
5x = 180 + 20
5x = 200
x = 200/5
x = 40
