Which statement is true?

All quadrilaterals have at least 1 pair of parallel sides.
Parallelograms have 2 pairs of congruent angles.
A rhombus is a rectangle.
A trapezoid is a parallelogram.

Answer:

496

Step-by-step explanation:

Answer:

It's the 2nd one

Step-by-step explanation:

So to find the perimeter you add all the sides together. So if 2 of the sides are 20 and 15, that means the other ones are 20 and 15.

Once you add those all together you get 70.

To find the area you multiply the two different sides, so that would be 20 and 15.

20 times 15 is 300.

Step-by-step explanation:

no solution is when numbers on either side of the equal sign are different

have both equations in each system look like

y = ....

then since both are equal to y

have both equations equal to each other to get the value of

x

system 1:

6x+3=6x+3

0=0

infinite

system 2:

1/2x-5= -2x-4

5/2x=1

x=2/5

one solution

system3

4y-x= -4

y=(x-4)/4= 1/4x-1

1/4x-1= 1/4x-1

infinte

system4:

1/2x=1/2x+3

0 does not equal 3

no solution

graph is in the attached picture

both equations are parallel to each other

Answer:

75 large and 50 small

Step-by-step explanation:

= 75 and 50

Answer: This is the anwser to test 1

The X on the start is 46 then just do 46 + 18 = 64 This is the anwser for letter A

This is gonna be the awnser for letter B

There are 46 students in the filmaking club and 18 on the yearbook

Test 2

This is the awnser to letter A The cost of the adult ticket is 8 dollars

So it will be 8 + 4 = 1,040 if its wrong then you can put 520 or just divide it example: 8 divided by 520, 4 divided by 520

Awnser for letter B is

Each adult ticket cost = 8 dollars

Each student ticket cost = 4 dollars

Hope it helps :)

Answer:

The answer is Quotient X: 4/10

3/5 minus 1/5 is 2/5. 4/10 can be simplified to 2/5, which is the answer.

Answer:

108

Step-by-step explanation:

a = pi(r^2) is the same as a = 3(6^2).

6 x 6 = 36

36 x 3 = 108

So the answer is 108 cm squared.

Answer:

The 8x11 pan.

Step-by-step explanation:

Because of the way math works, the 8x11 would be your best guess.

Answer:

A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches.

A cross section parallel to the base is a rectangle measuring 15 inches by 6 inches.

A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.

A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 4 inches by 15 inches.

A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.

Answer:

The answer is :

[tex] - 7 \sqrt{5} - 5 \sqrt{13} [/tex]

Step-by-step explanation:

[tex] \sqrt{5} - 5\sqrt{13} - 8 \sqrt{5} [/tex]

Combine like terms

[tex] - 7 \sqrt{5} - 5 \sqrt{13}[/tex]

Answer:

The answer is....D

Step-by-step explanation:

First I would make the fractions 1/8 and 2/3 have simular denominators

First I would have to find the LCD (Lease common denomitor)

Which would be 24

which changes the fractions to 3/24 and 16/ 24

Add teh fractions

19/24

Answer:

c

Step-by-step explanation:

Answer:

about 6.9

Step-by-step explanation:

first we have to find the missing side that doesn't have a "?". we can do this using pythagorean theorem. using the equation a^2 + 1^2 = 5^2 we know that this side is about 4.8. using this, we can use 4.8^2 + 5^2 = c^2. then, after doing this, we get about 6.9.

Step-by-step explanation:

keep in mind that a circle is 360 degrees so half (or two side by side angles) would equal 180 degrees.

opposite angle would be the same number

Answer:

9/2≈4.5

Step-by-step explanation:

mean is 4, 5,6,3

Find the mean of the list:

(4, 5, 6, 3)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 4 + 5 + 6 + 3:

(4 + 5 + 6 + 3)/(number of elements)

Counting, we see that the list has 4 elements:

(4 + 5 + 6 + 3)/4

4 + 5 + 6 + 3 = 18:

18/4

18/4 = 9/2:

Answer: 9/2≈4.5

Answer:

B

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

You have to find the average of the set of numbers by adding them all together, and divide them by how many numbers there are. In this case, the numbers are 6, 5, 3, & 2. You add 6, 5, 3, & 2 together and you get 16. Then you divide it by four since 4 numbers were provided. 16/4=4.
