Answer:

The statement 'Every square is a rhombus' is correct.

Step-by-step explanation:

Here are the reasons.

Is every rhombus a square?

Answer: No. Every rhombus is not a square, The reason is that rhombus does not contain any right angles, so it would not a square.

Every parallelogram is a rhombus?

Answer: No. Every parallelogram is a not rhombus as the rectangle has two pairs of parallel sides, so it would be a parallelogram, but it doesn't have equal sides so it would not be a rhombus.

Every square is a rhombus?

Answer. Yes, a rhombus is a quadrilateral with four equal sides. Every square contains 4 equal sides in length. Thus, every square would be a rhombus.

Every rectangle is a square?

No. Some rectangles would not be squares, because they don't have 4 equal length sides.

So, the statement 'Every square is a rhombus' is correct.

Keywords: square, rhombus, rectangle, parallelogram

How do u answer thiss

nekit [7.7K]

Answer:

15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.

Step-by-step explanation:

Length, Area, and Volume Scale Factors

If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is $a^2:b^2$ and the scale factor of their volumes is $a^3:b^3$ .

We are given the scale factor of the surface areas of two similar containers A and B as 4:25.

The length scale factor is

$\sqrt{4}:\sqrt{25}=2:5$

The volume scale factor is: $5^3:2^3$ = 125:8 = 15.625

Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.

Thus, after she pours the 15th container, in the middle of the next one, the work will be done

Lorico [155]

One set of magnet with 10% discount would cost
(6.4)*(1-0.10) =
6.4*0.9 = 5.76
For two sets of magnets
5.76*2 =11.52

Step-by-step explanation:

isolate the x by adding4 to each side of the equation

x - 4 = 9

+ 4 =+ 4

and then the -4 cancels out and you get x = 13

Fifteen dozen eggs were needed for baking four wedding cakes. The first cake

Mazyrski [523]

Answer:

96 eggs

Step-by-step explanation:

A dozen is equal to 12 eggs, so 15 dozen is equal to 180 eggs

(Because 15*12 = 180)

We already know how many eggs are required for the 1st cake: 12 eggs.

Then it says "each successive cake needs twice as many eggs as the previos cake".

(Successive means the cake directly after the previous cake)

Here's how we find the number of eggs needed for the 2nd cake:

The 1st cake needed 12 eggs, and because the 2nd cake is directly after the 1st cake, we are going to need two times the amount of 12 eggs.

This equation represents the above scenario:

12*2 = 24

So we need 24 eggs for the 2nd cake.

Now we repeat this process for the 3rd cake, finding twice the amount of eggs from the 2nd cake to find the amount of eggs needed for the 3rd cake:

24*2 = 48

And we repeat it once more for the 4th cake, using the eggs from the 3rd cake:

48*2 = 96

So here's the list of how many eggs are required for each of the cakes:

1st cake: 12

2nd cake: 24

3rd cake: 48

4th cake: 96

If you add all the eggs from each of the cakes, you will get 180, which is the number of eggs needed for all four cakes. So our answer is correct.

Hope this helps (●'◡'●)
