Question 1:

To start off this question, we can tell that this is a square because it has 4 right angles and 4 congruent sides.

A square has four parallel sides and 4 congruent sides, so a square is a rhombus and parallelogram. 

A square has 4 right angles, so it's also a rectangle.

A square has 4 sides, so it's also a quadrilateral.

The first choice is your answer.

Question 2:

Not all quadrilaterals are rectangles, so A is incorrect.

Not all quadrilaterals are squares, so B is incorrect.

All rectangles are types of quadrilaterals, so C is correct.

Not all quadrilaterals are parallelograms, so D is incorrect.

Thus, C is your answer.

Question 3: 

The first choice will not work because a rhombus will satisfy those conditions, and a rhombus is not always a square.

The second choice will work because only a square will satisfy that condition because only squares have 4 congruent sides along with equal diagonals.

Thus, the second choice is your answer.

Have an awesome day! :)

The small rectangle was enlarged to create the big rectangle.
kow [346]

Answer: the missing measure on the big rectangle is 30 feet.

Step-by-step explanation:

If the small rectangle was enlarged to create the big rectangle, it means that they are similar. This also means that the dimensions of the larger rectangle different form the dimensions of the smaller rectangle by a constant ratio or factor.

The smaller rectangle has a length of 12 feet and width of 2 feet. The larger rectangle has a length of x feet and width of 5 feet. This means that

x/12 = 5/2

Cross multiplying, it becomes

2x = 12 × 5 = 60

x = 60/2 = 30

Two identical jars are filled with equal numbers of marbles. The marbles are colored red or white. The ratio of red to white mar
IrinaK [193]
Let a=the number of white marbles in Jar 1
Let b=the number of white marbles in Jar 2
Total number of white marbles is a+b=90

Jar 1 has a white marbles and 7a red marbles so 8a marbles total
Jar 2 has b white marbles and 9b red marbles so 10b marbles total
Since both jars have equal amounts of marbles, 8a=10b

We have a system of equations:
a+b=90
8a=10b

The number of red marbles in Jar 2 is 9b so we solve for b

8a=10b
⇒a=\frac{5}{4}b
⇒\frac{5}{4}b+b=90
⇒\frac{9}{4}b=90
⇒b=40
Number of red marbles in Jar 2 is 9b=360

So there are 360 red marbles in Jar 2.
