Answer:

x/90 = 13/130(you can simplify this btw)

x90 x90

X = 9

Make both of them ratios

X to 90 and pick another random one 13 to 130.

Make sure to make them equal to eachother then just solve for x.

You can also compare it to 9 to 90

It would still work:

x/90 = 9/90

x90 x90

X = 9, x would also equal 9

Answer:

x = 9

Step-by-step explanation:

Assuming the rectangles are similar

13 x

------ = ---------

130 90

Using cross products

13*90 = 130*x

Divide each side by 130

13*90/130 = x

x = 9

Which of the following are solutions to the equation below?

Answer:

$\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}$

$x=3,\:x=-\frac{1}{2}$

Step-by-step explanation:

considering the equation

$2x^2\:-\:4x\:-\:3\:=\:x$

solving

$2x^2\:-\:4x\:-\:3\:=\:x$

$2x^2-4x-3-x=x-x$

$2x^2-5x-3=0$

$\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}$

$x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$\mathrm{For\:}\quad a=2,\:b=-5,\:c=-3:\quad x_{1,\:2}=\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\left(-3\right)}}{2\cdot \:2}$

solving

$x=\frac{-\left(-5\right)+\sqrt{\left(-5\right)^2-4\cdot \:2\left(-3\right)}}{2\cdot \:2}$

$x=\frac{5+\sqrt{\left(-5\right)^2+4\cdot \:2\cdot \:3}}{2\cdot \:2}$

$x=\frac{5+\sqrt{49}}{2\cdot \:2}$

$x=\frac{5+7}{4}$

$x=3$

also solving

$x=\frac{-\left(-5\right)-\sqrt{\left(-5\right)^2-4\cdot \:2\left(-3\right)}}{2\cdot \:2}$

$x=\frac{5-\sqrt{\left(-5\right)^2+4\cdot \:2\cdot \:3}}{2\cdot \:2}$

$x=\frac{5-\sqrt{49}}{4}$

$x=-\frac{2}{4}$

$x=-\frac{1}{2}$

Therefore,

$\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}$

$x=3,\:x=-\frac{1}{2}$

What is the answer to this problem above?

Ronch [10]

Answer:

Value of f (Parapedicular) = 7√6

Step-by-step explanation:

Given:

Given triangle is a right angle triangle

Value of base = 7√2

Angle made by base and hypotenuse = 60°

Find:

Value of f (Parapedicular)

Computation:

Using trigonometry application

Tanθ = Parapedicular / Base

Tan60 = Parapedicular / 7√2

√3 = Parapedicular / 7√2

Value of f (Parapedicular) = 7√2 x √3

Value of f (Parapedicular) = 7√6

Helpppp ASAP only the table

Elenna [48]

For the 2 tabs on the table you subtract and get your answer. And for 3 and 4 you divide 90 and 55, 42 and 30. Then try to divide the other ones too :)
