Put it a hole number so make the 20 become a hundred and then use the same common number and multiply it by the top and u have ur answer ..it will only work with an even number of 100

the common multiple is 5. take 5*20 thats 100. 5*5= 25. 25/100 is .. 25%

To convert $\frac{5}{20}$ to a percent, you must convert it to a decimal first

Divide the numerator(top) by the denominator(bottom)

5÷20=.25

All percents are based off of "100%" so multiply .25 by 100(%) which is 25%

Answer: 25%

What is the value of x ?

Contact [7]

Answer:

x = 19

Step-by-step explanation:

The two angles form a right angle

A right angle has a measure of 90 degrees

Thus, x + 14 + 3x = 90

^This is the equation we will use to solve for x

x + 14 + 3x = 90

step 1 combine like terms

x + 3x = 4x

we now have 4x + 14 = 90

step 2 subtract 14 from each side

90 - 14 = 76

14 - 14 cancels out

we now have 76 = 4x

step 3 divide each side by 4

4x / 4 = x

76 / 4 = 19

we're left with x = 19

Quadratic Equation

Natasha_Volkova [10]

Step-by-step explanation:

The sum of ages of two friends is 13 years.

The product of their ages is 42.

Let the age of 1st friend and 2nd friend is x, y respectively.

1 st condition= The sum of ages of two friends is 13 yrs.

i.e x+y = 13........ (I)

2nd condition= The product of their ages is 42.

i.e X*y = 42........(ii)

From equation (I)

X+y = 13

or, X = 13-y........ (iii)

Putting the equation (iii) in equation (ii).

X*y= 42

(13-y) * y = 42

13y - y^2 = 42

${y}^{2} - 13y + 42 = 0$

${y}^{2} - (7 + 6)y + 42= 0$

${y}^{2} - 7y - 6y + 42 = 0$

$y(y - 7) - 6(y - 7) = 0$

$(y - 6) (y - 7) = 0$

Either; y-6 = 0

y = 6

Or;

y-7=0

y = 7

Keeping the value of y as "7" in equation (ii)

x*y = 42

7x = 42

X = 42/7

Therefore, the value of X is 6.

Therefore, either 1st friend is 6 years and 2nd is 7 years.

Hope it helps...

I think you might need Desmos for graphing?? Explain your answer!

kotegsom [21]

Yes you are correct! This equation will make a parabola. The width when the arch is at ground level would be the x-intercepts, or zeros, of the parabola.

The vertex point is (0,12)

the axis of symmetry is 0

The zeros are (-4,0) and (4,0)

using the zeros take away the negative because something cant be negative feet wide and add the numbers together (4+4)

Your answer is 8

i attached the graph

Hope this helps you!

P.S. Can i get brainliest? :)
