George bought a model of a Viking ship for $68. If he paid
$5.10 in sales tax, what was the sales tax rate?

Answers

Answer:

We can convert 6.75% to a decimal by dividing by 100.

If x is the price of the house, then the sales tax is 0.0675x. The price of the house and the sales tax add up to $319,000.

x+0.0675x=319,000

Combe terms on the left.

1.0675x=319,000

Finally, divide both sides by 1.0675.

x=319,0001.0675=298,829.04

luisa is building a sand box in her backyard. she places four pieces of wood in a rectangle to form the frame. the rectangle is 4 feet long and 3 feet wide. how can she use a measuring tape to make sure that the corners of the frame will be right angles?

Answers

Answer:

As we know rectangles have 90 degree angles at all 4 of its corners.

In this question we know that the length is 4 feet while the bredth is 3 feet.

Therefore to solve this answer we can use the Pythagoras theorm.

By Pythagoras:

[tex]4^{2} + 3^{2} = diagonal^{2}[/tex]

Therefore the diagonal must be 5 feet

So if Luisa measures the diagonal with a tape and it measures 5

Then it proves that all 4 corners due have 90 degree angles

Step-by-step explanation:

We have to multiply by the number of the area.If it is 4 inches we multiply by 4

15 x 4 =60

What are similar figures?

Two figures are defined as similar triangles when they share these two features listed as follows:

Congruent angle measures, as both triangles have the same angle measures.Proportional side lengths, which helps us find the missing side lengths.

Hence the top left figure is similar with the figure given in this problem, as:
