I need help with these 2 problems please, thank you

Answer:

11. parallelogram, rectangle

12. parallelogram, rhombus

13. parallelogram, square

For parallelogram:

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

for rectangle:

A quadrilateral is a polygon in Euclidean plane geometry with four edges (sides) and four vertices (corners). Other names for quadrilateral include quadrangle (in analogy to triangle), tetragon (in analogy to pentagon and hexagon), and 4-gon (in analogy to n-gons for arbitrary values of n).

for rhombus:

In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond.

for Square:

·There are four methods that you can use to prove that a quadrilateral is a square. In the last three of these methods, you first have to prove (or be given) that the quadrilateral is a rectangle, rhombus, or both:

·If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).

·If two consecutive sides of a rectangle are congruent, then it’s a square (neither the reverse of the definition nor the converse of a property).

·If a rhombus contains a right angle, then it’s a square (neither the reverse of the definition nor the converse of a property).

·If a quadrilateral is both a rectangle and a rhombus, then it’s a square (neither the reverse of the definition nor the converse of a property).

Answer:

The probability is 0.81

Step-by-step explanation:

The probability we want to find here is that;

the mail was delivered before 2 pm the first day and also delivered before 2 pm the next day

what we have to do here is to

multiply together, the probability in the two cases (for both days)

So we have this as:

0.9 * 0.9 = 0.81

Answer:

.81

Answer:

x = 41

Step-by-step explanation:

All triangle angles add up to 180 so:

x + 90 + 49 = 180

x + 139 = 180

x = 180 - 139

x = 41

Answer:

F i think

Step-by-step explanation:

Answer:

x = 17

y = 8

QPR = 35º

QRP = 60º

Step-by-step explanation:

2x + 1 = x + 18

Subtract x from both sides

x + 1 = 18

Subtract 1 from both sides

x = 17

QPR = 2x + 1

QPR = 2(17) + 1

QPR = 35º

-------------------------------

8y - 4 = 4y + 28

Subtract 4y from both sides

4y - 4 = 28

Add 4 to both sides

4y = 32

Divide both sides by 4

y = 8

QPR = 8y - 4

QRP = 8(8) - 4

QRP = 60º

Answer:

2n^3

Step-by-step explanation:

Hey there!

7/4 = 35/m

CROSS MULTIPLY BOTH of your NUMBERS

7(m) = 4(35)

7(m) = 7m

4(35) = 140

NEW EQUATION: 7m = 140

DIVIDE 7 to BOTH SIDES

7m/7 = 140/7

CANCEL out: 7/7 because that gives you 1

KEEP: 140/7 because that gives you the value of m

140/7 = m

Solve above and you have the answer of m

140/7 = 20

Therefore, the value of m = 20

Answer: m = 20

Good luck on your assignment and enjoy your day!

Answer:

2

Step-by-step explanation:

add 16 to zero

4x2=16

Divide 4x by 2 and 16 by two

4x=8

divide 8 by 4

x=2

Answer:

x = ± 2

Step-by-step explanation:

Given

4x² - 16 = 0 ( add 16 to both sides )

4x² = 16 ( divide both sides by 4 )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

solutions are x = - 2, x = 2

Answer:

7.85

Step-by-step explanation:

firstly convert the 45 deg into radians

which is 0.785398 rads multiply it by ten ..

using the formula s=r∅

Answer:

Correct Answer Is 7.85

Step-by-step explanation:

Since 45 degrees is 1/8th of a circle Then you would find the circumference divided by 8.

10= Radius Then Circumference= 62.83

(Divide Circumference by 8) = 7.85 (Answer)

Answer:

15 marbles in a jar.

Step-by-step explanation:

[tex]\frac{y}{3000} :\frac{1}{200}[/tex]

y · 200 = 3000 · 1

200y = 3000

200y ÷ 200 = 3000 ÷ 200

y = 15
