Multiply -90/11 by -55/72 with explanation...

Pls fast...Will mark Brainliest for the best one...

Answer: The answer would be B

Write out the equation in slope-intercept form:

y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)

Subtract -5/3 from both sides of the equation:

y+5/3x=6

Subtract 6 from both sides:

y+5/3x-6=0

Multiply both sides by 3 to get rid of the fraction:

3y+5x-18=0

Then arrange the numbers to x and y are on one side by itself:

3y+5x=18

And that's your answer!

Hope this helped you!

Image result for What is true about the interior angles of a non-regular decagon?

A regular decagon has 10 equal-length sides and equal-measure interior angles. ... An irregular decagon has sides and angles that are not all equal or congruent. A convex decagon bulges outward, with no interior angle greater than 180° . A concave decagon have indentations, creating interior angles greater than 180° .

Answer:

well a regular has 10 equal-lenght sides and equal measure interior angles....

Answer:

2000mm:80mm:40mm

because 1 m is 1000mm and 1 cm is 10 mm so 2m will be 2000 mm and 8cm will be 80 mm

The simplified ratio will be equal to 10 : 40: 2.

In mathematics, a ratio is a comparison between two quantities or numbers. It is expressed as the quotient or fraction of one number divided by another.

To simplify the ratio of 2m: 8cm: 40mm, we need to convert all the measurements to the same units. One meter is equal to 100 centimeters, so we can convert meters to centimeters by multiplying by 100. One centimeter is equal to 10 millimeters, so we can convert centimeters to millimeters by multiplying by 10.

2m: 8cm: 40mm

= 200cm : 8cm : 40mm (2m = 200cm)

= 200cm : 800mm : 40mm (8cm = 80mm)

= 10 : 40 : 2 (divide all terms by 40 to simplify)

Therefore, the simplified ratio is 10 : 40: 2.

Answer:Matti has 3pencils

Step-by-step explanation:

Given that Jorge has 5pencils

Renaldo has 1more than Jorge that means ,he has 5 +1=6pencils

But also

Renaldo =3Chang-Lin

6==3Chang-Lin

Chang-Lin = 6/3 =2

Since Chang-Lin has 2, Matti having 1more I than Chang-Lin will have 2+1=3pemcils

r^2 + 14r + 33

Step-by-step explanation:

Apply the "FOIL" method for multiplying two binomials:

(r+3) (r+11) = r^2 (first terms) +

                    + 33 (last terms) +

                     + 11r (outer terms) +

                      + 3r (inner terms)

Combining ilke terms, we get:

r^2 + 14r + 33

Answer:

1.)x=15.9

2.)x=17.49

3.) x=7.29

Step-by-step explanation:

For all the questions use Pythagorean Theorem which is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex]

C=opposite of hypotenuse

A=Leg

B=Leg

1.) [tex]6^{2}[/tex]+[tex]b^{2}[/tex]=[tex]17^{2}[/tex]

Simplify the equation

36+[tex]b^{2}[/tex]= 289

Subtract 36 from both sides

[tex]b^{2}[/tex]=289

Square Root both sides to equal 15.9

Do the same for questions 2-3

Answer:

P(x) = x² - 15x + 50

Step-by-step explanation:

We write the polynomial function P(x), given that P(x) = 0 has the given roots, x = 5 and x = 10.

Since x = 5 and x = 10 are the roots of P(x) = 0, it follows that (x - 5) and (x - 10) are factors of P(x) = 0. So, P(x) = (x -5)(x - 10) = 0

Expanding the brackets, we have

x² - 10x - 5x + 50 = 0

Simplifying, we have

x² - 15x + 50 = 0 = P(x)

Thus,

P(x) = x² - 15x + 50

19.87 = 100%

If you divide both sides by ten, you would get what ten percent is.

1.987 = 10%

Multiply this by two to get 20%.

3.974 = 20%

Minus twenty percent from the original amount.

18.87 minus 3.974 = 15.886 after the discount.

  (x -2)² +(y -4)² = 25

Step-by-step explanation:

The area of a square is half the product of the diagonals, so that product is 50·2 = 100. This is the square of the diameter, so the square of the radius is 100/4 = 25. Then the circle equation is ...

  (x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r
