h²=p²+b²

20²=x²+12²

400-144=x²

256=x²

16²=x²

square will be cancelled so answer is 16

Answer:

h²+b²=H²

x²+12²=20²

x²=20²-12²

x²=400-144

x²=256

look for the square root,,,which is 16

and so x=16

A circular pond is modeled by the equipment x^2+y^2=225. A bridge over the pond is modeled by a segment of the equation x-7y=-75

makkiz [27]

X² + y² = 225
x - 7y = -75

x = 7y - 75

x² + y² = 225
(7y-75)² + y² = 225
(7y - 75)(7y - 75) + y² = 225
49y² - 525y - 525y + 5625 + y² = 225
50y² - 1050y + 5400 = 0
50(y² - 21y + 108) = 0

y² - 21y + 108 ⇒ (y - 12)(y - 9)

x = 7(12) - 75
x = 84 - 75
x = 9 ⇒ (9,12)

x = 7(9) - 75
x = 63 - 75
x = -12 ⇒ (-12,9)

Find parametric equations for the line through point P(-4,5,2) in the direction of the vector (-6,6,-5)

tigry1 [53]

The vector v (-6, 6, -5) points in the direction of itself, so we start there.

We can capture all points on the line through the origin and the point (-6, 6, -5) by scaling v by an arbitrary real number t.

The line through point P and pointing in the same direction as v is parallel to the other line that passes through the origin. Then the line we want can be obtained by translating the line through the origin by a vector p that points to (-4, 5, 2), so the vector equation for this line is

r (t ) = p + t v

r (t ) = (-4, 5, 2) + t (-6, 6, -5)

r (t ) = (-4 - 6t, 5 + 6t, 2 - 5t )

To get the parametric equations, simply take out the components:

x (t ) = -4 - 6t

y (t ) = 5 + 6t

z (t ) = 2 - 5t

Jesse is playing a game with a number cube with faces numbered 1 through 6. What is the probability of rolling a number that is

lana [24]

Answer:

The probability of rolling a number that is even and a multiple of 3 is $\frac{1}{6}$

Step-by-step explanation:

The total possible outcomes of cube = { 1, 2, 3 , 4 , 5 , 6}

Now, let E: Event of getting an even number and a multiple of 3

So, out of all the outcomes, {6) is the ONLY possible favorable outcome.

$\textrm{P(E)} =\frac{\textrm{Number of favorable outcomes }}{\textrm{Total number of outcomes}}$

or, $P(E) = \frac{1}{6}$

Hence, the probability of rolling a number that is even and a multiple of 3 is $\frac{1}{6}$

Karra is at the dollar store buying bags of chips for her sleepover party. For every 5 bags of chips she buys, she pays $6. What

Alexus [3.1K]

Answer:

$1.20

Step-by-step explanation:

Given that:

Price paid to buy 5 bags of chips = $6

To find:

Price per bag of chips in two digits after the decimal.

Solution:

To find the price of each bag of chips, we need to divide the price of 5 bags of chips with 5.

i.e. we need to divide $6 with 5, then we will get the price of each bag of chips.

$\text{Price of each bag of chips}=\dfrac{\text{Price of 5 bags of chips}}{5}\\\Rightarrow \dfrac{\$6}{5} = \bold{\$1.2}$

Therefore, the answer is:

Price of each bag of chips is $1.2.
