Answer:
1. A. contain a right angle
1. B. opposite sides are parallel
2. (c) 2 pairs of parallel sides
3. (b) 2 sides of equal length
Step-by-step explanation:
Here you are asked to find patterns and to make use of the definitions of different geometric figures.
<h3>1.</h3>
The figures in Circle A do not all have the same number of sides, or sides of the same length. However, they do all have at least one right angle.
The figures in Circle B are rectangles and parallelograms. The attributes listed in question 2 can be used here. They all have two pairs of parallel sides.
<h3>2.</h3>
As we observed in question 1, rectangles and parallelograms share the feature of 2 pairs of parallel sides.
A kite may have 2 pairs of equal-length sides. While a square and a rhombus have 4 sides of equal length, that description is not true of rectangles and parallelograms in general.
Angles in a rectangle are all 90°, while those in a parallelogram may not be. The offered descriptions of angles do not apply to apply to both shapes.
<h3>3.</h3>
An isosceles triangle has two sides equal length and two equal angles. An equilateral triangle is a special case of an isosceles triangle in which all three sides are equal, as are all three angles. The description that applies to both kinds of triangles is 2 sides of equal length.

Answer:
5.6 miles
Step-by-step explanation:
Firstly, we need to find the unit rate (the number of miles in 1 minutes).
To get this, we need to divide total miles ran (7 miles) by the total minutes taken (80 minutes). Thus, we will have MILES PER MINUTE.
7 miles ÷ 80 minutes = 7/80 miles per minute
Now,
We want number of miles in 64 minutes. Since we know "PER MINUTE", we simply multiply that with 64 to get number of miles in that amount of time.
THus,
So, in 64 minutes, Maria can run 5.6 miles
Answer:
x1 = 275 miles (shorter)
x2 = 318 miles (longer)
Step-by-step explanation:
Let
x1 = be the shorter route
v1 = speed of the car in the shorter route
t1 = time it took to cover shorter route
x2 = the longer route
v2 = speed of the car in the longer route
t2 = time it took to cover longer route
x1 + 43 = x2 (1)
v2 = v1 -2 (2)
v2 = x2/t2 = x2/6
v1 = x1/t1 = x1/5
This means that
v2 = v1 -2 =>
x2/6 = x1/5 -2
The system of equations results
a. x1 -x2 = -43
b. x1/5 - x2/6 = 2
Solving this system of equations, we find that
x1 = 275 miles
x2 = 318 miles
