A rectangle has an area of (4x2 + 10) square inches. The length of the rectangle is (2x2 + 5) inches.

How many inches is the width of the rectangle?

Answers

Answer 1

Answer:

Area of the rectangle = 4x^2+8x = 4x(x+2)

So if the length is (x+2), the width of the rectangle = 4x(x+2)/ (x+2) = 4x.

The length is > the width, so

x+2 > 4x, or

2 > 3x, or

(2/3) > x or

x < (2/3).

Say x = 5/9 which is < 2/3, the length = 2 + 5/9 or 23/9 and the width =20/9, which is logical.

The area of the shaded region is 85 units cubed.

Answer:

85 Square Units

Step-by-step explanation:

We need to start by finding the area of the triangle:

(base*height)/2

[tex]\frac{17*10}{2} =85[/tex]

Then we find the area of the rectangle:

Height*Width= 170

Then we finally take the area of the rectangle (170) and subtract the area of the triangle (85) and we get the answer of 85.

Find the perimeter and area of a plank of size 300 cm * 30 cm​

Answers

Given :

Length of the plank = 300 cm.Breadth of the plank = 30 cm.

To Find :

The perimeter and area of the plank.

Solution :

Perimeter of the plank :

[tex]\: {\qquad \dashrightarrow \sf 2 \times (Length + Breadth) }[/tex]

[tex]\: {\qquad \dashrightarrow \sf{{ 2 \times (300 + 30) \: cm }}}[/tex]

[tex]\: {\qquad \dashrightarrow \sf{{ 2 \times (330) \: cm }}}[/tex]

[tex]\: {\qquad \dashrightarrow \sf{{ 600 \: cm }}}[/tex]

Area of the plank :

[tex]\: {\qquad \dashrightarrow \sf (Length \times Breadth) }[/tex]

[tex]\: {\qquad \dashrightarrow \sf (330 \times 30) \: {cm}^{2} }[/tex]

[tex]\: {\qquad \dashrightarrow \sf 9 000 \: {cm}^{2} }[/tex]

Step-by-step explanation:

Given :-

Length = 300cmWidth = 30 cm

To find :-

Perimeter and area of plank

Solution :-

Perimeter of rectangular plank = 2(L+W)

putting the values,

perimeter = 2(300+30)cm

⇝660 cm

Area of rectangular plank = L × W

putting the known values ,

Area = 300 × 30 cm²

⇝ 9000cm²

M is directionally proportional to r^3. when r=4, M=160. work out value of M if r=2

Answers

Answer:

M = 20

Step-by-step explanation:

given M is directly proportional to r³ then the equation relating them is

M = kr³ ← k is the constant of proportion

to find k use the condition when r = 4, M = 160 , then

160 = k × 4³ = 64k ( divide both sides by 64 )

[tex]\frac{160}{64}[/tex] = k , then

k = 2.5

M = 2.5r³ ← equation of proportion

when r = 2 , then

M = 2.5 × 2³ = 2.5 × 8 = 20

The BOLD number is your answer, and the other ones are the sequence. oof, that was a lot of calculating!

Thanks!

Answer:

0.046875

Step-by-step explanation:

Each number is being divided in half each time.

24 / 2 = 12

12 / 2 = 6

6 / 2 = 3

3 / 2 = 1.5

1/5 / 2 = 0.75

0.75 / 2 = 0.375

0.375 / 2 = 0.1875

0.1875 / 2 = 0.09375

0.09375 / 2 = 0.046875 <--- This is the ninth term of the sequence.

elimination method steps

Answers

Answer:

Remarks:

The method used in solving the example above is called the elimination method, because we eliminate one variable first, to get a linear equation in one variable. In the example above, we eliminated y. We could also have eliminated x. Try doing it that way. 2. You could also have used the substitution, or graphical method, to solve this problem. Try doing so, and see which method is more convenient.

steps of elimination method: Step 1:

First multiply both the equations by some suitable non-zero constants to make the coefficients of one variable (either x or y) numerically equal. Step 2: Then add or subtract one equation from the other so that one variable gets eliminated. If you get an equation in one variable, go to Step 3. If in

Step 2:

we obtain a true statement involving no variable, then the original equations has infinitely many solutions. If in Step 2, we obtain a false statement involving no variable, then the original pair of equations has no solution, i.e., it is inconsistent.

Step 3:

Solve the equation in one variable (x or y) so obtained to get its value.

Step 4:

Substitute this value of x (or y) either of the original equations to get the value of the other variable.

Find an equation of a square root curve of the form
= √ + that approximately contains the points
(3,7) and (6, 8)

Answers

Answer:

  y = √(5x+34)

Step-by-step explanation:

The regression formula that matches a square root function to these points can be worked out by a suitable calculator. The attachments shows the points are matched exactly by the function ...

  y = √(5x+34)

__

If you would like to work this by hand, you can put the (x, y) point values into the proposed equation and see what the coefficients need to be:

  y = √(ax +b)

  7 = √(3a +b)   ⇒   49 = 3a +b

  8 = √(6a +b)   ⇒   64 = 6a +b

Subtracting the first equation from the second, gives ...

  (64) -(49) = (6a +b) -(3a +b)

  15 = 3a   ⇒   a = 5

  49 = 3(5) +b   ⇒   b = 34

The first three steps of completing the square to solve the quadratic equation x² + 4.0 - 6 = 0 are shown
below.
Step 1: x2 + 4x = 6
Step 2: x² + 4x + 4 = 6+4

What is probability?

Probability is simply how likely something is to happen.

Probability formula

[tex]P(E )=\frac{Number\ of \ favorable\ outcomes }{Total\ number \ of outcomes}[/tex]

Where,

P(E) is the probability of an event.

What is the fair game?

A fair game is the game in which there is an equal chance of wining or losing.

According to the given question.

Two coins are tossed.

[tex]\implies sample\ space= \{ HH, HT, TH, TT\}[/tex]

[tex]\implies total\ number \ of outcomes = 4[/tex]

Therefore,

The probability that you win is given by

[tex]P(E_{1} )=\frac{Number\ of \ favorable\ outcomes }{Total\ number \ of outcomes}[/tex]

[tex]\implies P(E_{1} )= \frac{1}{4}[/tex]                            (getting HH is a favorable outcome)

[tex]\implies probability\ of\ losing\ the\ game = 1-\frac{1}{4} =\frac{3}{4}[/tex]

And, the probability that your friend wins the game is given by

[tex]P(E_{2}) = \frac{Total\ number\ of\ favorable\ outcomes\ }{Total\ number\ of\ outcomes}[/tex]

[tex]\implies P(E_{2} )=\frac{1}{4}[/tex]                    (getting TT is the favorable outcome)

[tex]\implies probability\ of\ losing\ the\ game = 1-\frac{1}{4} =\frac{3}{4}[/tex]

Hence, the game is fair because there is an equal chance of winning an losing the game.
