Answer:

1 hour 39 Minutes

Step-by-step explanation:

At 8:09 P.M

Only the first plane was in the air

At 9:14 P.M

Both Planes were in the air

At 10:53 PM

First plane lands

For how long were both planes in the air at the same time.

Both planes were in the air between the 9:14 P.M and 10:53 PM

Duration = 1 hour 39 Minutes

Answer:

13

Step-by-step explanation:

it's a 5,12,13 triangle

and we can find the sides by Pythagorean theorem:

a^2 + b^2 = root of c

25 + 144 = 169

root of 169 = 13

Answer:

2.23456790123 x 10 ^ 2

Step-by-step explanation:

8.1 x 10^10 = 810,000,000,00( 10 Bounces from the decimal point) ( think of it as frog jums each jump is a single multiplication of 10 ^ 1)

1,810,000,000,000 = 1,81 x 10 ^12

1,81 x 10^ 12 - 8.1 x 10^ 10 =22.3456790123 = 2.23456790123 x 10 ^ 2

Answer:

the fraction of quart of milk does each of the four friend get is  1 ÷ 24

Step-by-step explanation:

The computation of the fraction of quart of milk does each of the four friend get is shown below:

= Sharing quart of milk × fraction of friends

= 1 ÷ 6 × 1 ÷ 4

= 1 ÷ 24

Hence, the fraction of quart of milk does each of the four friend get is  1 ÷ 24

Answer:

0.9043secs and 0.3456secs

Step-by-step explanation:

Given the height of an overhand volleyball modeled as h=-16t^2+20t+6.

If the height is 11feet, then;

11 = -16t^2+20t+6.

-16t^2+20t+6 - 11 = 0

-16t^2+20t-5 = 0

Multiply thriugh by -1

16t^2-20t+5 = 0

Factorize

t = 20±√20²-4(16)(5)/2(16)

t = 20 ±√400-320/32

t = 20 ±√80/32

t = 20 ±4√5/32

t = 20±8.94/32

t = 28.94/32 and 11.06/32

t = 0.9043 and 0.3456

Hence the required time are 0.9043secs and 0.3456secs

Answer:

26°,51°,103°

Step-by-step explanation:

sum of angles=180°

y = -2(x + 4)(x - 3)

y = -2(x² + x - 12)

y = -2x² -2x + 24

Answer:

the thrid answer

Step-by-step explanation:

Answer:

They are not equivalent.

Step-by-step explanation:

Before we solve the question, we need to know that from the laws of indices:

A^x x A^y = A^(x+y).

7 to the power of 8th power means 7^8

7^8 times 7 means 7^8 x 7. From the laws of indices we have 7^8 x 7 = 7^9.

7 to the power of 3rd power means 7^3

7^3 times 7 to the power of 3rd power means 7^3 x 7^3. From the laws of indices we have 7^3 x 7^3 = 7^6.

Obviously, 7^9 ≠ 7^3 therefore, they are not equivalent.

Answer:

bx + bc = d would be checked as yes

Step-by-step explanation:

if you follow pemdos it would go as the following:

b(x+c) = d

b(x) + b(c) = d

bx + bc = d

it is not express because the line is parallel at y axis

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

In similar triangles, the ratios of the length of the corresponding sides are equal.

[tex]\frac{CD}{ED}=\frac{GD}{FD}\\\\[/tex]

[tex]\frac{48}{5x-2}=\frac{40}{2x+7}\\[/tex]

Cross multiply,

48*(2x + 7) = 40*(5x - 2) {use distributive property: a*(b+c)=(a*b)+ (a*c)}

48*2x  + 48*7 = 40*5x - 40*2

  96x  + 336   = 200x - 80       {Subtract 96x from both sides}

             336   = 200x - 96x - 80

               336 =  104x - 80 {Add 80 to both sides}

      336 + 80 = 104x

               416 = 104x      {divide both sides by 104}

        416/104 = x

x = 4

Answer:

y = -7

Step-by-step explanation:

To find the y-intercept, you need to plug the coordinates into the equation.

y = 0x + b

-7 = 0(5) + b

-7 = b  

Answer: It will be set: a), e), g)

Step-by-step explanation:

In order to form a triangle then the sum of its angles has to be equal to 180 degrees. In order to find out if it’s possible to form a triangle from a specific set of angles, then you have to add them up and see if they are equal to 180 degrees. If they are then it’s a triangle if they less than or greater than 180 then a triangle cannot he formed.
