Answer:

1/98

Step-by-step explanation:

Step 1: Translate statement into equation.

$\frac{1}{7}/x = 14$
$\frac{1}{7x}=14$

Step 2: Multiply both sides by 7x.

$\frac{1}{7x} * 7x = 14 * 7x$
$1 = 98x$

Step 3: Divide both sides by 98.

$\frac{1}{98} =\frac{98x}{98}$
$x = \frac{1}{98}$

Step 4: Check if solution is correct.

$\frac{1}{7}/\frac{1}{98}$
$\frac{1}{7}*98$
$14$

Therefore, the answer is 1/98.

Martin throws a ball straight up in the air. the equation h(t) = -16t^2 + 40t + 5 gives the height of the ball, in feet, t secon

Lisa [10]

Answer:

2.62 seconds

Step-by-step explanation:

Let

t ----> the time in seconds

h(t) ----> he height of the ball, in feet

we have

$h(t)=-16t^2+40t+5$

we know that

When the ball hits the ground, the height is equal to zero

$-16t^2+40t+5=0$

The formula to solve a quadratic equation of the form

$at^{2} +bt+c=0$

is equal to

$t=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-16t^2+40t+5=0$

$a=-16\\b=40\\c=5$

substitute in the formula

$t=\frac{-40\pm\sqrt{40^{2}-4(-16)(5)}} {2(-16)}$

$t=\frac{-40\pm\sqrt{1,920}} {-32}$

$t=\frac{-40+\sqrt{1,920}} {-32}=-0.12\ sec$

$t=\frac{-40-\sqrt{1,920}} {-32}=2.62\ sec$

therefore

The solution is t=2.62 seconds

Please help I don't understand

Mars2501 [29]

Answer:

3. 3:5

4. 4:1

Step-by-step explanation:

Just ratios I believe, myb if it's wrong but that should be it.

Since 3 & 5 aren't divisible by anything the scale factor is just 3:5.

Since 24 & 6 are divisible by a common number, being 6, you'd divide 24:6 & get a scale factor of 4:1.

If six more than the product of a number and -2 is greater than 10, which of the following could be that number

laiz [17]

To get that number in the problem, you need to translate first the word problem into mathematical expression.

We will let x as the number.
six more than the product of a number and -2 is greater than 10 can be written as (-2x) + 6 > 10
We will now solve for x to get the number.
   (-2x) + 6 > 10
Add -6 to both sides of the equation
      -2x + 6 - 6 > 10 - 6
      -2x > 4
Divide both sides of the equation with -2
Take note that if we divide a negative number in inequality, the inequality symbol will be change from greater than to less or from less than to greater than.
   -2x / -2< 4 / -2
   x < -2

Therefore, the number that we are looking for is less than -2.
