Answer:

8 to 40

6:30

2/10

Step-by-step explanation:

To check if this is the answer you can multiply the first number of each of these ratios by 5. (We multiply them by five because it is the second number in the ratio 1:5)

8 times 5 equals 40 -so this one is right

6 times 5 equals 30 -yep this one is right too

2 times 5 equals 10 -yeperdoodle

Yeah..so these are the answers! let me know if this helps you out.

Can you plz help me with this, because I don’t know how to do this and can u plz explain how to do it
Alecsey [184]

Answer:

Step-by-step explanation:

You can start this in may ways but let's start by isolating one of the parenthesis:

x (x² - 5) = - (x - 3)

x³ - 5x = -x + 3 (here I multiplied x for what's inside the parenthesis and the "minus" signal by the other parenthesis which was (x - 3))

x³ - 5x + x = 3

x³ -4x = 3

x³ -4x -3 = 0 (now this right here is a "depressed cubic equation" and it's one of the toughest sit of all time, so good luck with that, you might wanna take a look at this:

ytb/watch?v=rNDy2ZFvG1E

or maybe I'm doing something wrong and it's simpler than that, but whaterver...)

Answer:

<h2><em><u>120</u></em><em><u> </u></em><em><u>square</u></em><em><u> </u></em><em><u>units</u></em><em><u> </u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>, </u></em>

Base of the parallelogram = 10

Height of the parallelogram = 12

<em><u>Therefore</u></em><em><u>, </u></em>

Area of the parallelogram = <em>base</em><em> </em><em>×</em><em> </em><em>height</em><em> </em>

= 10 × 12

= 120

<em><u>Hence</u></em><em><u>,</u></em>
