1.0 is what percent of 3.5

Mathematics
1 answer:
olasank [31]2 years ago
6 0

Answer:

28.57%

Step-by-step explanation:

Let the required percent be x

1.0 is what percent of 3.5 is written as;

1.0 = x% of 3.5

1.0 = 0.01x * 3.5

0.01x = 1/3.5

0.01x = 0.2857

x = 0.2857/0.01

x = 28.57%

Hence 1.0 is 28.57% of 3.5

Finger [1]

Answer:

49x + 114

Step-by-step explanation:

[   [ fireplace ] x   = area of 5x^{2}                   ]  x + 6

     5x

   patio               = area of 5x^{2} + 49x + 114

5x + 19

 

(5x + 19) ( x + 6) = 5x^{2} + 19x + 30x + 114

(5x^{2} + 49x + 114)                     -   (5x^{2} )                         =           49x + 114

(area of patio and fireplace) - (area of fireplace)     =       (area of patio only)

Find the volume of the square pyramid below.
miv72 [106K]

Hello!

\bf ANSWER

The volume of the square pyramid is approximately \boxed{ \bf 19.19~km^3}

____________________________________________________________

\bf EXPLANATION

V = a^{2}\frac{h}{3}

First, we must find the area of the square base.

A = l * w

A = 3.5 * 3.5

A = 12.25 km^2

The area of the base is 12.25 km^2. Now, multiply the base area by the perpendicular height. Then divide by 3.

V = (12.25 * 4.7) / 3

V = 19.1916666667

V ≈ 19.19 km^3

PLEASE HELP!!!!<br><br> f(x)= {____for____<br> {____for____
hammer [34]

9514 1404 393

Answer:

  f(x)=\left\{\begin{array}{ccc}3&\text{for}&-5\le x < 0\\1-x&\text{for}&0

Step-by-step explanation:

The left section is defined at x = -5, but not at x = 0, so the interval for that definition is -5 ≤ x < 0. The function value on that interval is constant: 3.

The right section is defined a x = 5, but not at x = 0, so the interval for that definition is 0 < x ≤ 5. That section is a straight line with a slope of -1 and a y-intercept of 1. The function value on that interval can be written -x+1.

Then the piecewise definition is ...

  f(x) = {3, for -5 ≤ x < 0; -x+1, for 0 < x ≤ 5}
