All four-sided figures are parallelograms true or false
pls explain why

Answers

Answer 1

Answer:

True

Step-by-step explanation:

Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms.

Answer 2

A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.

Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides.

Parallelograms are quadrilaterals with two sets of parallel sides. Since squares must be quadrilaterals with two sets of parallel sides, then all squares are parallelograms. This is always true. (actually is true)

A clock runs 5 minutes slow every hour. The clock was set
at the proper time 12 hours ago. The correct time now is 3 p.m.
How many minutes will elapse before the clock indicates 3 p.m.?

Answers

60 minutes because 12 (hours) times the 5 minutes is 60 minutes
2:00 because if you multiply 5 times 12, it will equal 60. Subtract 3:00 from 60 mins, you get 2:00 pm

K=1/2mv square root of 2
rearrange for m:​

Answers

Answer: V = The square root of (2K/M)

We are starting with the formula: K = 0.5MV^2

Our first steps to isolate V would be to multiply by 2 and divide by M on both sides of the equation.

2K/M = V^2

Now, we just have to take the square root of both sides of the equation

The equation rearranged for m is [tex]m = (2K) / v^2[/tex].

This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.

To rearrange the equation [tex]K = (1/2)mv^2[/tex] for m, we can follow these steps:

Step 1: Multiply both sides of the equation by 2 to remove the fraction:

[tex]2K = mv^2[/tex]

Step 2: Divide both sides of the equation by[tex]v^2[/tex] to isolate m:

[tex](2K) / v^2 = m[/tex]

Therefore, the equation rearranged for m is [tex]m = (2K) / v^2[/tex].

This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.

Step-by-step explanation:

Perimeter means the sum of length of all sides of a figure.

So, the perimeter of this triangle would also be the sum of the length of its sides.

Your business has two branch stores. The recent physical inventory reports that the merchandise value for each store is: Store A $750,000, and Store B $580,000. The merchandise book value for each store is: Store A $757,000, and Store B $600,000. What is the dollar amount of shrinkage for each store?

Answers

Answer: Store A: 7,000 Store B: 20,000

Step-by-step explanation:

The amount of shrinkage for store A is $7000 and for store B is $20000.

What is loss?

"If the selling price of an item is less than the cost price, then the difference between the cost price and the selling price of an item is called the loss".

For the given situation,

The merchandise book value for store A = $757,000

The merchandise book value for store B = $600,000

Based on physical inventory reports,

The merchandise value for store A = $750,000

The merchandise value for store B = $580,000.

The amount of shrinkage determines the loss and it is calculated by taking the difference between the values.

Store A = [tex]757000-750000[/tex]

⇒ [tex]7000[/tex]

Sore B = [tex]600,000-580000[/tex]

⇒ [tex]20000[/tex]

Hence we can conclude that the amount of shrinkage for store A is $7000 and for store B is $20000.

A, E and B lie on a straight line segment. C, D and B lie on a straight line segment. BD = 3m, CD = 12m and AB = 19m. Work out the length of BE. Give your answer as a decimal. please help

Answers

Answer:

3.8m

Step-by-step explanation:

If A, E and B lie on a straight line segment. C, D and B lie on a straight line segment, based on their similarities,

AB/CB = BE/BD

Given

BD = 3m,

CD = 12m

AB = 19m.

CB = CD+BD

CB = 12+3 = 15m

On substituting

19/15 = BE/3

Cross multiply

15BE = 19×3

15BE = 57

BE = 57/15

BE = 3.8m

Hence the length of BE is 3.8m
