Which of the following statements is correct baded on the number line below?​

Answer:

A. Width = 25   Length = 15

Step-by-step explanation:

Length = L = Width - 10

Width = W

Perimeter of a rectangle

=> 2 (L + B) = 80

=> 2 (W - 10 + W) = 80

=> 2 (2W - 10) = 80

=> 4W -20 = 80

=> 4W -20 + 20 = 80 + 20

=> 4W = 100

=> 4W/4 = 100/4

=> W = 25

Width = 25

Length = 25 - 10 = 15

So, the answer is A.

Answer:

  swap 1,2; swap 3,4

Step-by-step explanation:

Put the numbers in scientific notation, with one digit left of the decimal point.

The number with the largest exponent is largest.

If exponents are equal, the number with the largest mantissa is the largest.

Here, the exponents are already in order, so you need only order the mantissas for each exponent. Ascending order is ...

Hi there! :)

Answer:

[tex]\huge\boxed{D, x -4}[/tex]

---- Starting with: ----

x² - 10x + 24

Since we have a leading coefficient of 1, simply find two numbers that sum up to -10 and multiply into 24.

By guessing and checking, we get the numbers -6 and -4. Put these into factors:

(x - 6)(x - 4)

Therefore, a binomial present in factored form is D. x - 4

Answer:

Step-by-step explanation:

7). Since the points J, K and L are on a same line, these points are collinear.

8). Point M is a point which is on the same plane with the points J, K and L but it is not collinear as the points J, K, and L are.

9). Points J, K, L and M are on the same plane (horizontal plane) but point N is not coplanar with these points.

10). Since a plane is named using 3 points lying on it. Therefore, JKL is the appropriate name of the given plane with these points.

Answer:

JKL is the appropriate name of the given plane with these points.

Answer:

8640 square inches

Step-by-step explanation:

There are 12 inches in one foot so there would be 12 * 12 = 144 square inches in 1 square foot. Therefore, there are 144 * 60 = 8640 square inches in 60 square feet.

Question:

Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the  water. At the end of his jump, Danny was 2.3 meters below the surface of the water.

The following equation describes this situation  14.2 + (-16,5) = -2.3 .

What does -16.5 tell us?

Answer:

The displacement between his current position and his initial position

Step-by-step explanation:

Given

[tex]Initial\ Position = 14.2m[/tex]

[tex]Final\ Position = -2.3m[/tex]

[tex]14.2 + (-16.5) = -2.3[/tex]

Required

What does -16.5 represents?

To understand this, we need to first calculate the displacement between his initial and final position

[tex]Displacement = Final\ Position - Initial\ Position[/tex]

[tex]Displacement = -2.3m - 14.2m[/tex]

[tex]Displacement = - 16.5m[/tex]

So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)

5(0.3) + 2y = 20

| 5(0.3) + 2y = 20

| Multiply 5 and 0.3 to get 1.5

\/

1.5 + 2y = 20

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We subtract 1.5 from both sides.

2y = 20 - 1.5

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Subtract 1.5 from 20 to get 18.5.

2y = 18.5

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Divide both sides by 2.

[tex]y = \frac{18.5}{2}[/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Expand [tex]\frac{18.5}{2}[/tex] = 9.25 by multiplying both numerator and the denominator by 10.

[tex]y =\frac{185}{20}[/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Reduce the fraction [tex]\frac{185}{20} = 9.25[/tex] to lowest terms by extracting and canceling out 5.

[tex]y =\frac{37}{4}[/tex].

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[tex]\frac{37}{4} = 9.25[/tex] in decimal form.

Answer:

y = 9/5

4th Option

Step-by-step explanation:

Step 1: Write out function f(y)

f(y) = 5y - 3

Step 2: Define variable from problem

f(y) = 6

Step 3: Replace variable

6 = 5y - 3

Step 4: Add 3 to both sides

9 = 5y

Step 5: Isolate y by dividing both sides by 5

y = 9/5

Answer:

400 feet

Step-by-step explanation:

We just need to find h when t = 5. To do so, we can plug t = 5 into the function, which would be:

h = -16t² + 120t + 200

  = -16 * 5² + 120 * 5 + 200

  = -400 + 600 + 200 = 400 feet

Answer:

h = 400 feet

Step-by-step explanation:

given t = 5 seconds

h = -16t² + 120t + 200

just substitute t = 5

h = -16(5)² + 120(5) + 200

h = 400 feet

Answer:

98.02

Step-by-step explanation:

Take 26 and multiply by 277%

26 * 277%

Change to decimal form

26 * 2.77

72.02

That is the amount of the increase

Now add it to the original amount

26+72.02

98.02

Answer:

98.02

Step-by-step explanation:

[tex]26 + 26 \times \frac{277}{100} \\ = 26 + 26 \times 2.77 \\ = 26 + 72.02 \\ = 98.02[/tex]

Answer:

13.2

Step-by-step explanation:

Given

[tex]10x = 132[/tex]

Required

Determine the initial quantity

The interpretation of this question is to solve for the value of x

To start with:

[tex]10x = 132[/tex]

Divide both sides by 10

[tex]\frac{10x}{10} = \frac{132}{10}[/tex]

[tex]x = \frac{132}{10}[/tex]

[tex]x = 13.2[/tex]

Hence, the initial quantity is 13.2

Probability that both marbles drawn will be green = 1 / 20

Step-by-step explanation:

(It is assumed that marbles are not returned in the bag)

[tex]p(1st \: marble \: drawn \: is \: green) = \frac{5}{20} [/tex]

[tex]p(2nd \: marble \: drawn \: is \: green) = \frac{4}{20} [/tex]

Multiplying theses we get :

Answer:

(-10,8)

Step-by-step explanation:

So our original point is (-6,9).

A translation of 4 units to the left means that the x-value would go left by 4. In other words, we subtract 4 to -6. We subtract because going to the left means that it's going to the negative direction.

A translation of down 1 unit means that the y-value would go down by 1. In other words, we subtract 1. Again, we subtract because going downwards means that it's going to the negative direction.

Therefore, the new point would be:

Answer:

[tex]A=73.5\text{ cm}^2[/tex]

Step-by-step explanation:

The formula for an area of a triangle is:

[tex]A=\frac{1}{2}bh[/tex]

Where b is the base length and h is the vertical height.

From the triangle, we can see that the base is 21 cm while the vertical height is 7. Thus:

[tex]A=\frac{1}{2}(7)(21)[/tex]

Multiply:

[tex]A=\frac{1}{2}(147)[/tex]

Multiply:

[tex]A=73.5\text{ cm}^2[/tex]

And that's our answer :)

The Area of triangle is 73.5 square cm.

We have from the figure,

Base of triangle = 21 cm

Height of triangle = 7 cm

side of triangle = 15 cm

We know the formula for Area of Triangle

Area of Triangle = 1/2 x base x height

Now, plugging the value of base and height in the formula we get

Area of triangle = 1/2 x  base x height

= 1/2 x 21 x 7

= 147/2

= 73.5 square cm

Step-by-step explanation:

area of shaded region = area of whole rectangle - area of unshaded region

Area of a rectangle is length × width.

A = 5x(3x+2) - (x(5x-2))

Expand brackets.

A = 15x² + 10x -(5x² - 2x)

Distribute negative sign.

A = 15x² + 10x - 5x² + 2x

Combine like terms.

A = 10x² + 12x
