Step-by-step explanation:

Given function:

A model rocket is launched off the ground at an initial velocity of 80 feet per second.

The function becomes:

Correct option is B.

Answer: 3/4 feet

Step-by-step explanation:Conversion a mixed number 3 5/

12

to a improper fraction: 3 5/12 = 3 5/

12

= 3 · 12 + 5/

12

= 36 + 5/

12

= 41/

12

To find new numerator:

a) Multiply the whole number 3 by the denominator 12. Whole number 3 equally 3 * 12/

12

= 36/

12

b) Add the answer from previous step 36 to the numerator 5. New numerator is 36 + 5 = 41

c) Write a previous answer (new numerator 41) over the denominator 12.

Three and five twelfths is forty-one twelfths

Conversion a mixed number 2 2/

3

to a improper fraction: 2 2/3 = 2 2/

3

= 2 · 3 + 2/

3

= 6 + 2/

3

= 8/

3

To find new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/

3

= 6/

3

b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8

c) Write a previous answer (new numerator 8) over the denominator 3.

Two and two thirds is eight thirds

Subtract: 41/

12

- 8/

3

= 41/

12

- 8 · 4/

3 · 4

= 41/

12

- 32/

12

= 41 - 32/

12

= 9/

12

= 3 · 3/

3 · 4

= 3/

4

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(12, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 3 = 36. In the next intermediate step , cancel by a common factor of 3 gives 3/

2x-6=20

2x=26

x=13

b 7-2x/4=9

-2x=8

x=-4

Answer:

x=3

Step-by-step explanation:

8-6x=18x

8-6x+6x=18x+6x

8=24x

x=3

Answer:

x=3

Step-by-step explanation:

First we have to get x by itself-

8-6x=18x     If you add 6x to -6x it chancels out

     +6x  +6x

8=24x        Now we have to divide by 8

/8  /8

x=3    

Answer:

The ans is 0.8

Step-by-step explanation:

80% = 0.8 in decimal form.

Percent means 'per 100'. So, 80% means 80 per 100 or simply 80/100.

If you divide 80 by 100, you'll get 0.8 (a decimal number). Read more below on this webpage.

As you can see, to convert from percent to decimal just divide the percent value (80) by 100, and remove the "%" sign.

Answer:

6.5units

Step-by-step explanation:

Find the length side of the smaller square

The area of the square is equal to

A = a^2

so

a^2 = 13

a = √13 units

step 2

Find the length side of the larger square

The area of the square is equal to

A = b^2

so

b^2 = 29.25

b = √29.25 units

step 3

Find the value of x

Applying the Pythagoras Theorem

x^2 = a^2 + b^2

x^2 = 13 + 29.25

x^2 = 42.25 units

x = √42.25

x = 6.5 units

The area of the square adjacent to the third side of the triangle is 85 square units.

Important information:

According to the Pythagoras theorem:

[tex]a^2=b^2+c^2[/tex]

Where, a is hypotenuse and b, c are two legs of a right-angle triangle.

Area of a square is the square of side length. So, [tex]b^2=35[/tex] and [tex]c^2=50[/tex]. Now,

[tex]a^2=35+50[/tex]

[tex]a^2=85[/tex]

Therefore, the area of the square adjacent to the third side of the triangle is 85 square units.

First we need to find all the interior angles.  So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180.

2x + x + 60 = 180

Now lets start to solve. First let's subtract the 60 from both sides.

2x + x = 120

Now we need to add the x's together.

3x = 120

Now we must divide the 120 by 3 to get x by itself.

x = 40

Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so <EHG would be equal to 80.

ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do!

Step-by-step explanation:

Firstly let's calculate the unknown angles in triangle ABC

2x + x + 60° = 180° { being sum of angles of triangle }

3x = 180° - 60°

3x = 120°

x = 120° / 3

x = 40°

2x = 2 * 40° = 80°

Now since it is said that triangle ABC and triangle EHG are similar so

< EHG = < ABC = 2x = 80°

Hope it will help :)

Answer:

x=18

Step-by-step explanation:

add 2y to both sides 5x=2y+88

subtract 88 from both sides 2y=5x-88

substitute 2y in the second equation for 5x-88

3x+10x-176=58

add like terms 13x-176=58

add 176 both sides

13x=234

x=18

Answer:

( 18, -6.5 )

Step-by-step explanation:

First choose which method you plan on using: Substitution or Elimation. I chose elimination based off preference.  

How to solve using Elimination:

5x -2y = 88  (multiply every number in this equation by two)

3x+4y=58

10x -4y = 176

3x+4y=58      (combine these two equations)

13x = 234  (isolate x by dividing by 13 on both sides)

x = 18         (this is your value for x)

3(18) +4y=58   (plug in for x)

54+4y=28        (solve)

4y = -26            (subtract 54 from both sides)

y = -6.5             (this is y)

write answer in (x, y) format

( 18, -6.5 )

Answer:

16

Step-by-step explanation:

p is directly proportional to M

p = km

given that k is the constant of proportionality

128 = 8k

k = 128/8

k = 16

the equation thus is p = 16M

Step-by-step explanation:

Remove parentheses.

15−7x−20=0.5(6x−14)

Simplify  15-7x-2015−7x−20  to  -7x-5−7x−5.

-7x-5=0.5(6x-14)

−7x−5=0.5(6x−14)

3 Expand.

-7x-5=3x-7

−7x−5=3x−7

4 Add 7x7x to both sides.

-5=3x-7+7x

−5=3x−7+7x

5 Simplify  3x-7+7x3x−7+7x  to  10x-710x−7.

-5=10x-7

−5=10x−7
