0.3:0.1

Step-by-step explanation:

first convert the % to decimals.

75%=0.75

25%=0.25

then look for a common factor and divide be that, in this case its 5.

0.75/5=0.15

0.25/5=0.5

now since these arent in the simplified form, you gotta divide again by 5.

0.15/5=0.3

0.5/5=0.1

Pythagorean theorem
for a right triangle with legs legnth a and b and hytponuse c
a^2+b^2=c^2

the legnht of th eladder is the hypotnuse
the 3 feet is bottom leg
height is other leg

10=c
3=a
b=?
3^2+b^2=10^2
9+b^2=100
minus 9 both sides
b^2=91
sqrt both sides
b=√91
aprox
b=9.53939


answer is √91 feet or aprox 9.53939

Explain how 50 tens x 4 hundreds = 40 tens x 5 hundreds
Anna007 [38]
50 tens is equal to 500 because if you multiply a number by 10, you just add a 0 behind it.
4 hundreds is literally just 400.
So 500 x 400 = 200,000

40 * 10 = 400
5 * 100 = 500
400 x 500 = 200,000

so both sides are equal to 200,000 and therefore the equation is true.

Answer: a) 6, 0, 10       b) yellow/orange line  

Step-by-step explanation:

a) Plug the x in the y functions, y = 2x² + x

when x = -2, y = 2(-2)² + (-2) = 8 - 2 = 6

when x = 0, y = 2(0)² + (0) = 0 + 0 = 0

when x = 2, y = 2(2)² + (2) = 8 + 2 = 10

b) By looking the table, the equation has a point (0,0), only blue and yellow/orange line has the passed the point (0,0), so we delete the red line option.

And we choose a point (1,3), then only yellow/orange line has passed the point (1,3). So the yellow/orange line fits the equation.
