Answer:

0.8888

Step-by-step explanation:

Step-by-step explanation:

Remember: when we divide fractions, we always:

• Flip the sign (change it to a multiplication sign)

• Flip the second fraction (4 goes on top and 3 goes on the bottom)

Now we have the rules covered, let's set up our expression.

[tex]\frac{2}{3} *\frac{4}{3}[/tex]

To multiply, we just have to multiply across. 2 • 4 is 8, and 3 • 3 is 9.

Our final answer: [tex]\frac{8}{9}[/tex]

Answer:

option B is correct -7 is the answer

Step-by-step explanation:

=4⁴-3³.(12-3)-20

=256-27×(9)-20

=256-243-20

=256-263

=-7

hope it will help ^_^

Answer:

[See Below]

Step-by-step explanation:

First you'll solve the parenthesis part:

* 12 - 3 = 9

Then Solve the exponents:

* 4^4 = 256 (4 x 4 x 4 x 4)

* 3^3 = 27 (3 x 3 x 3)

Rewrite:

* 256 - 27 x 9 - 20

Multiply:

* 27 x 9 = 243

Subtract:

* 256 - 243 = 13

* 13 - 20 = -7

So the answer would be B, -7

(Remember to use PEMDAS to solve)

Answer:

-58

Step-by-step explanation:

The first term (a₁) is 7 and the common difference (d) is 2 - 7 = -5.

Explicit formula of arithmetic sequence: aₙ = a₁ + (n - 1) * d

aₙ = 7 + (n - 1) * (-5) = 7 - 5n + 5 = -5n + 12

Therefore, a₁₄ = -5 * 14 + 12 = -58.

Step-by-step explanation:

This question requires an attachment.

However, if you follow my explanation, you'll arrive at your answer

The area of a parallelogram is:

[tex]Area (A)= Base (b) * Height (h)[/tex]

[tex]A = b * h[/tex]

To solve for Height, we simply make h the subject of formula

[tex]h = \frac{A}{b}[/tex]

In this question, we have that A = 54

Now, let's assume base (b) = 6.

This implies that

[tex]h = \frac{54}{6}[/tex]

[tex]h = 9[/tex]

Or;

Assume that b = 3

[tex]h = \frac{54}{3}[/tex]

[tex]h = 18[/tex]

So, whatever the base of the parallelogram is;

You can easily solve for the height using the above steps

Answer:

Step-by-step explanation:

acceleration, a = 20 m/s^2

initial velocity, u = 0 since it starts from rest

final velocity, v = 400 m/s

v = u + at

400 = 0 + 20 t

400 = 20 t

t = 400 / 20

t = 20 sec

Hope this helps

plz mark as brainliest!!!!

It will take 20 sec the rocket reach a velocity of 400 m/s

There are three equation of motions that can be used when motion of the object is under constant acceleration and on a straight path.

They are listed below as:

[tex]v = u + at\\\\s = ut + \dfrac{1}{2} at^2\\\\v^2 = u^2 + 2as[/tex]

We are given that manned rocket accelerates at a rate of 20 m/s2 during launch

The acceleration, a = 20 m/s^2

The initial velocity, u = 0 since it starts from rest

The final velocity, v = 400 m/s

Therefore, v = u + at

400 = 0 + 20 t

400 = 20 t

t = 400 / 20

t = 20 sec

Hence, It will take 20 sec the rocket reach a velocity of 400 m/s

Answer:

63

Step-by-step explanation:

The answer is 63 because k/3 =63

k/3-9=12

We move all terms to the left:

k/3-9-(12)=0

We add all the numbers together, and all the variables

k/3-21=0

We multiply all the terms by the denominator

k-21*3=0

We add all the numbers together, and all the variables

k-63=0

We move all terms containing k to the left, all other terms to the right

k=63

An equation is formed when two equal expressions. The value of k in the given equation is 63. The correct option is D.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the equation k3-9=12.

Now, for the given equation the value of k can be found by solving the equation,

k/3 – 9 = 12

k/3 – 9 + 9 = 12 + 9

k/3 = 21

k/3 × 3 = 21 × 3

k = 63

Hence, the value of k in the given equation is 63.

Answer:

  8y -2 = 2x

Step-by-step explanation:

The equation of the perpendicular line will have the coefficients of x and y swapped, and one of them negated. The constant can be found by substituting the given point value:

  8y +constant = 2x . . . . coefficients swapped; former y-coefficient negated

  8(2) +constant = 2(7) . . . . . fill in given point values (x, y) = (7, 2)

  constant = 14 -16 = -2 . . . . subtract 16

The equation can be written as ...

  8y -2 = 2x

_____

Additional comment

Personally, I prefer standard form, which has common factors removed from the coefficients, and has the constant separated from the variable terms:

  x -4y = -1

Some like the slope-intercept form better:

  y = 1/4x +1/4

Apparently, your curriculum author doesn't care how the equation of the line is written, so we have answered with the same form that was given.

Answer:

Step-by-step explanation:

that is the answer

You need the starting point, and another point that helps direct where the ray is aimed. Call these two points A and B.

Saying "Ray AB" means we extend a line through AB such that the line goes forever through B and beyond B, but we do not do the same for point A. The point A is effectively a cliff where no road goes on the other side of it. Check out the diagram below to see what I mean. The arrow means the line goes on forever in that direction.

Answer:

d. 0.6 > 4/7

Step-by-step explanation:

a. 1.5 > 5/3

From part a, it is given that 1.5 is greater than 5/3

changing 5/3 to decimal figure, we get 1.67

Thus, the claim that 1.5 > 1.67 is not valid because 1.67 is greater than 1.5

b. 2.5 < 0.25

given that 2.5 is less than 0.25 is not valid because 2.5 is greater than 0.25

c.  0.07 > 7/10

if we convert 7/10 to decimal figure, we get 0.7

the claim that 0.07 is greater than 0.7 is not valid because 0.7 is greater than 0.07

d. 0.6 > 4/7

If we convert 4/7 to decimal figure, we get  0.57

Therefore, the claim that 0.6 is greater than 0.57 is accurate and valid

Hence, Option d is the correct answer.

Answer:

Length of the pole = 10.8 ft

Depth of the snow = 7.2 ft

Step-by-step explanation:

The correct question is

A vertical pole is placed in the ground at a campsite outside Salt Lake City, Utah. One winter day, 1/6 of the pole is in the ground, 2/3 of the pole is covered in snow, and 1.8 ft is above the snow. How long is the pole, and how deep is the snow.

The fraction of the pole in the ground = 1/6

The fraction of the pole in the snow = 2/3

The length of the pole above the snow = 1.8 ft

Total fraction of the length of the pole = 1

For the fraction of the length above the snow, we solve as

1/6 + 2/3 + [tex]x[/tex] = 1

[tex]x[/tex] = 1 - 1/6 - 2/3 = 1/6

This means that the length of the pole above the snow 1.8 ft = 1/6 of the length of the pole.

Also, the fraction of the pole in the ground = 1/6

this means that the length of the pole in the ground = 1.8 ft

If 1/6 of the length of pole is 1.8 ft,

the length of the pole = 1.8 ft x 6 = 10.8 ft

Length of the pole in the snow = 2/3 of 10.8 = 2/3 x 10.8 = 7.2 ft

this means that the the snow is 7.2 ft deep

Answer:

19

Step-by-step explanation:

Assuming that [tex]l[/tex] represents length and [tex]w[/tex] represents width, we can make a systems of equations and solve for l and w.

[tex]2l+2w=60[/tex], since the perimeter of a rectangle will be double the length plus double the width.

Also we can make the equation [tex]l = 2w+3[/tex], as stated in the last part of the question.

We can now substitute the value of [tex]2w+3[/tex] into the equation [tex]2l+2w=60[/tex] as l.

[tex]2(2w-3) + 2w = 60\\\\4w-6+2w=60\\\\6w-6=60\\\\6w=66\\\\w = 66\div6\\\\w = 11[/tex]

So we know the width is 11. Now that we know the width, we can substitute it back into the equation  [tex]l = 2w+3[/tex] to find the length.

[tex]l=2\cdot11-3\\\\l=22-3\\\\l=19[/tex]

So the length is 19.
