Answer:
every parallelogram is a square? False
every rectangle with four congruent sides is a square? True
every rectangle is a quadrilateral? True
every quadrilateral is a rectangle? False
Step-by-step explanation:
every parallelogram is a square?
A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.
every rectangle with four congruent sides is a square?
Square require 4 congruent sides and 4 right angles. Rectangles already have 4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.
every rectangle is a quadrilateral?
A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.
every quadrilateral is a rectangle?
A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.
Answer:
4. D
5. B
6. B
Step-by-step explanation:
Flowcharts are used to show the steps of a process in a subsequential order. They are not used to represent relations or functions therefore the answer is D
In a function each x value had its own corresponding y value. To be more specific the x value cannot repeat.
In answer choice A the x value 3 and -3 repeats therefore is is not a function
in answer choice b each x value has it's own y value. So this might be the answer but just to be safe let's check the other
In answer choice C the x value 2 repeats multiple times therefore it is not a function
In answer choice D the x value 4 repeats therefore it is not a function
So we can conclude that the answer is B
The dependent variable is the variable the depends on another variable to get it's value. in the description of the question it says that the number of products on his plastic bag lists INFLUENCES how many plastic bags he brings to the store.This means that the number of plastic bags depends on the number of products on the plastic bags lists. Hence the answer is B
Answer:
Complementary Angles
Step-by-step explanation:
When all angles are added together they have a sum of 90°. Two angles that have a sum of 90° are complementary angles.
I know this is 90° because it is a right angle.
Are you supposed to estimate or get an exact answer? If you're estimating you can see if the number is close to any perfect squares. In this case 63 is very close to 64, and 48 is very close to 49. The answers can then be estimated to be approximately 8 and 7, respectively.
Answer:
Step-by-step explanation:
-3 because you subtract 19 to 16
