Answers

Answer 1

Answer:

D) All rectangles are parallelograms is the answer.

All rectangles have two pairs of congruent and parallel sides

What is a math rectangle?

A rectangle is a polygon with four sides that are parallel and equal on the opposite side. This is one of the types of quadrilaterals where all four angles are equal to right angles or 90 degrees. A rectangle is a special type of parallelogram with all angles equal. A

rectangle is a type of rectangle with equal parallel sides and 90 degrees for all four vertices. Therefore, it is also called a parallelogram. A rectangle is also called a parallelogram because the opposite sides are equally parallel.

Answer 2

Answer:

Answer:

D) All rectangles are parallelograms.

Step-by-step explanation:

A) A trapezoid must have congruent sides. NO

because all sides may have different lengths

B) Every angle in a quadrilateral must be less than...

Angles of quadrilateral can have different measures.

It is important that they meet the condition:

The angles in any quadrilateral add up to 360°.

C) All rectangles are squares. NO

All squares are rectangles. The square has all sides congruent. The rectangle has two pairs of congruent sides.

D) All rectangles are parallelograms. YES

All rectangles have two pairs of congruent and parallel sides

How to solve for x on a quadratic function

Answers

To find the x-intercepts of any equation, substitute 0 in for y and solve for x. So, we have 0 = 3x2+ x + 1. Now, use the quadratic equation to solve for x, wich a = 3, b = 1, and c = 1: So, now we can find the value of the x-intercepts and not have to estimate!

Anita can paint the shed in 5 h. If Kris helps her, they can paint the shed in 3 h. How long will it take Kris to paint the shed alone?

Answers

Anita can paint the shed in 5 hours. If Kris helps her, they can paint the shed in 3 hours. How long would it take Kris to paint the shed alone?
----
Anita rate = 1/5 job/hr
Together rate = 1/3 job/hr
Kris rate = 1/x job/hr
Equation:
rate + rate = together rate

1/x + 1/5 = 1/3
----
Multiply thru by 15x to get:
15 + 3x = 5x
2x = 15
x = 7.5 hrs (time for Kris to do the job alone)

If a cylinder holds a volume of 100 cm3, and is 30 cm tall, which is the area of the bottom of the cylinder?

Answers

=πr2h

Area of circle
=πr2

=V/h
=100/30
≈3.33cm

Well, lets break this down.

Volume = area of base * height

we know that the volume is 100 and the height is 30 so we can work backwards

100 = b * 30

now divide both sides by 30

(100/30) = b * (30/30)

the height cancels itself out and we are left with...

base = 3.33

therefore your answer is 3.33 cm^2

3÷0.1=30Choose all of the statements that explain how the quotient relates to the dividend.
Dividing 3 by 0.1 tells how many tenths are in 3 ones.

3÷0.1 is the same as 30÷1, which is 30.

It takes 10 tenths to make 1 whole, so it will take 3 times 10 tenths to make 3 wholes. 3×10=30.

The quotient has 110 of the value of the dividend so the dividend must be 10 times greater.

The 3 in 30 is 1 place to the right of the 3 in the whole number 3 which increases the value of the number 10 times.

Can some one tell me which is bigger 5/8 or 0.58.also can someone tell em which is bigger out of 15% or 1/5

this is a two question i am asking

Answers

I always find that decimals are easier to work with so 5/8 as a decimal is 0.625. So 0.625 compared to 0.58 is bigger, so 5/8 is bigger than 0.58.15% = 0.15 and 1/5 = 0.2 So 1/5 is bigger than 15%
