square root property

Answer:

55

Step-by-step explanation:

First, you do 22 divided by 2, which is 11. Then, you would multiply that by 5 which equals 55. So, the number is 55.

Answer:

55

Step-by-step explanation:

x=missong number

of means *

2/5 * x = 22

multilpy both sides by 5/2

x =22* 5/2

x = 55

Answer: The package reaches the ground in

4.67 s

and hits the ground with a speed of

33.8 m/s

Answer:

3m/s or option 1

Step-by-step explanation:

Given,

Height(h)=90m

time(t)=30s

Speed(v)=?

Now,

Speed(v)=distance/time

v=height/time(Since,height here is the distance covered by the balloon)

v=90/30

v=3

Unit of speed is m/s

Therefore,v=3m/s

By the way,this is a question related to physics

Question:

Which of the equivalent expressions for P(x) reveals the profit when the price is

zero without changing the form of the expression? P(x) = -3x² + 432x - 1680

a) P(x) = -3(x - 4)(x - 140)

b) P(x) = -3(x - 72)² + 13872

Find the profit when the price is zero

Answer:

- P(x) = -3(x - 140)(x - 4).

- P(0) = -1680

Step-by-step explanation:

Given

P(x) = -3x² + 432x - 1680

Required

- Find equivalent of P(x)

- Find P(x) when x = 0

To find the equivalent of P(x), we simply factorize P(x) = -3x² + 432x - 1680.

This is done as follows

P(x) = -3x² + 432x - 1680

P(x) = -3x² + 12x + 420x - 1680

P(x) = -3x(x - 4) + 420(x - 4)

P(x) = (-3x + 420)(x - 4)

Further expand -3x + 420

P(x) = -3(x - 140)(x - 4).

Hence, the equivalent of

P(x) = -3x² + 432x - 1680

without changing its form is

P(x) = -3(x - 140)(x - 4).

When price is 0, then x = 0.

Substitute 0 for P(x) in P(x) = -3(x - 140)(x - 4).

P(0) = -3(0 - 140)(0 - 4).

P(0) = -3(-140)(-4)

P(0) = -1680

Hence, the profit when price is 0 is -1680

Answer:

The sum of the inverses of two rational numbers is 5 by 6, and the difference of the inverses of the numbers is 1 by 6. Calculate the sum and product of numbers.

Sum = a + b = 5

Product = a ₓ b = 6

Step-by-step explanation:

[tex]\frac{1}{a} +\frac{1}{b} =\frac{5}{6}[/tex]

[tex]\frac{1}{a} -\frac{1}{b} =\frac{1}{6}[/tex]

Add both equations together

[tex]\frac{1}{a} +\frac{1}{a} +\frac{1}{b} -\frac{a}{b} =\frac{5}{6} +\frac{1}{6}[/tex]

2 / a = 6/6

2 / a = 1

a = 2

we replace in any relation a

1 / 2 + 1 / b = 5 / 6

3b + 6 = 5b

5b - 3b = 6

2b = 6

b = 3

Sum = a + b = 2 + 3 = 5

Product = a ₓ b = 2 ₓ 3 = 6

Answer:

1/2

Step-by-step explanation:

There are exactly 6 shaded regions; for every shaded region, there is also an unshaded region -- making this value 6 as well.

There are 12 possible outcomes, and 6 events

To determine probability, we divide the number of events by the number of possible outcomes, like this:

[tex]6/12=1/2\\1/2=.50\\[/tex]

.50 = 50% or 1/2 chance.

Answer:

The median is the middle number.

Step-by-step explanation:

You have to order the numbers from least to greatest, or greatest to least, and choose the number in the middle. Since there is an even number of values, you have to take the mean of the two middle numbers. I hope this helps.

Answer:

F(x)=(x-3)(x+8)(x-11)=0

(x-3)=0, (x+8)=0, (x-11)=0

X=3

X=-8

X=11

Answer:

1x+ 1y =11

10x + 5y = 80

x = the cost of a taco = $5

y = the cost of a burrito = $6

Step-by-step explanation:

x = the cost of a taco

y = the cost of a burrito

1x+ 1y =11

10x + 5y = 80

rearange 1st equation as y = 11 -x and plug in into the 2nd one for y:

10x + 5( 11-x) = 80 distribute left side

10x + 55 - 5x = 80 combine like terms

10x - 5x = 5x

5x + 55 = 80 subtract 55 from both sides

5x = 80 - 55

5x = 25 divide by 5

x = 5

plug in for y in 1st equation y = 11--x =11-5 = 6

Answer:

8 p^ (19)

Step-by-step explanation:

8p^15 x (–p)^4

Since this is even, a negative number to an even power is the same as the positive number to the even power

8p^15 x (p)^4

We know a^b * a ^ c = a^ (b+c)

8 p^(15+4)

8 p^ (19)

Step-by-step explanation:

420/35

12

12*35=420

Answer:

The corresponding base is 12 cm.

Step-by-step explanation:

The area of a parallelogram is calculated with the formula of A=bh, where b is the base and h is the height.

You can apply the problem to the formula:

420=b(35)

To solve, work backwards.

Divide 35 to both sides.

420 divided by 35 is 12

b=12
