Answer:

Step-by-step explanation:

The distance between two points is given by

d = sqrt( (y2-y1) ^2 + (x2-x1)^2)

= sqrt((-9-5)^2 + (-3- -3)^2)

= sqrt(( -14)^2 +(-3+3)^2)

= sqrt((-14)^2 +0)

= sqrt((14)^2)

= 14

What part of 5 and 3/4 is 7/10?

Effectus [21]

Answer:

7/10 is approximately 12.17% of 5 3/4.

To solve this, you'd first convert each value into a decimal.

7/10 - 0.70

5 3/4 - 5.75

Look at each value as a whole number. For example, if you wanted to find 3 of 8, you'd solve 3/8. The same principle applies here. If you were to type this into your calculator, you'd get 0.12173913043.

Next, convert the decimal (your quotient) into a percentage.

Remember, to convert a decimal to a percent, you have to multiply it by one hundred. So, .12173913043 would be 12.173913043.

After you convert, you can round to the nearest hundredth- that would give you 12.17%.

Check your answer:

To do this, you could multiply 5.75 by 12.17%, which would give you 6.99775.

You could then take this value and round it to 7.

Hope this helps,

<h3>What is a triangular prism?</h3>

A triangular prism is a closed solid that has two parallel triangular bases connected by a rectangle surface.

A triangular prism has a height of 6 meters and a triangular base with the following dimensions.

The figure is shown below.

Then the area of the base of the triangular prism will be

$\rm Area = \dfrac{1}{2} \times 16 \times 6\\\\Area = 48$

The mistake was minus sign before the 15 and putting 15x² instead of 15x³.

The correct answer is:

$-5x^{2} (3x-4)\\ = -15x^{3} + 20x^{2}$

the width of a rectangle is 6inches less than twice it’s length. Find the dimension of the rectangle if it’s area is 108 square

Sindrei [870]

Answer:

Width = $12$ Length = $9$

Step-by-step explanation:

We have to first find an equations with the given variables:

$w = 2L - 6$

Now apply the area format:

$Length * Width$

Since the area is 108 square inches

$108 = l * w$

$108 = l(2l-6)$

$108 = l(2l) + l(-6)$

$108 = 2l^2 - 6l$

Simplify:

$(l-9) * (l+6) = 0$

Since no number can be negative

$w = 2*9(L)-6$

$w = 12$

$l=9$
