find the perimeter and area of a square whose side measures

1)3point5 (3.5)
2)1m 20cm​

Step-by-step explanation:

the linear inequality is how to measure value of a line through quality and quantity.

Answer:

x < 45

Step-by-step explanation:

Let's call that number x. x/3 - 5 < 10, and we can add by five on both sides then multiply by 3 on both sides to get that x < 45.

Answer:

9.099 seconds

Step-by-step explanation:

The rock hits the surface of the moon when is t is 0.

[tex]-t^2 + 8t + 10 = 0\\t^2 - 8t - 10 = 0[/tex]

Use the quadratic formula

t = -1.099 and 9.099

Since time can't be negative, the answer is t = 9.099

Answer: Monitor C is the different one.

Step-by-step explanation:

The aspect ratio is the relationship between width and height.

So we only need to see the quotients between width and height for each monitor and see which quotient is different.

Monitor A:  

Quotient = 1152/864 = 1.333....

Monitor B:

Quotient = 800/600 = 1.333...

Monitor C:

Quotient = 1920/1080 = 1.777...

Monitor D:

Quotient = 1600/1200 = 1.333...

We can see that the one with a different aspect ratio is monitor C.

Answer:

Width=11

Length=16

Step-by-step explanation:

P=2L+2W

54=2(5+w)+2w

Open the brackets

10+2w+2w=54

10+4w=54

Collect the like terms

4w=54-10

4w/4w=44/4

W=11

Since the length is 5m longer

Therefore:11+5=16

Width=11

Length=16

Answer:

15 mph

Step-by-step explanation:

You need to find how much each side of the table is changing each time and change that into a fraction. In this example, the change in time is .5 hours. Repeat with the other side to get 12.5 miles. Next you change it into a fraction with the distance over the time to get 12.5/.5. Type this into the calculator to get the answer which is 15 mph.

Step-by-step explanation:

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\text{4R3+R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

and,

"A set of numbers arranged in rows and columns so as to form a rectangular array."

"A matrix formed by combining the columns of two matrices to form a new matrix."

"The mathematical operations that are performed on rows of a matrix."

For given question,

We have been given an augmented matrix.

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

We need to perform the row operation 4R3 + R1 → R1

To perform above row operation,

- First multiply the third row by 4. ([tex]4R_3[/tex])

- Add the new third row (4[tex]R_3[/tex]) with the first row.

- Then replace Row 1 with the result.

The resultant augmented matrix would be,

[tex]\begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

That is,

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\text{4R3+R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

Now, we need to perform the row operation  [tex]\frac{1}{4}[/tex] R1 → R1 on the above resultant augmented matrix.

To perform above row operation,

- Multiply the Row 1 by the reciprocal of 4.

- Then replace Row 1 with the result.

The resultant augmented matrix would be,

[tex]\begin{bmatrix}4 & 0 & -4& |& 4 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\frac{1}{4} \text{R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{1} & \bold{0} & \bold{0}& |& \bold{1} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

Therefore,

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\text{4R3+R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

and,

[tex]\begin{bmatrix}4 & 0 & -4& |& 4 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\frac{1}{4} \text{R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{1} & \bold{0} & \bold{0}& |& \bold{1} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

Complete Question:

There are 10 marbles. What is the probability of drawing 2 blue marbles if the first marble is NOT placed back in the bag before the second draw.

2 yellow, 3 pink, 5 blue    

Answer:

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Step-by-step explanation:

Given

[tex]Blue = 5[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 10[/tex]

When the first blue marble is selected, the probability is:

[tex]P(B_1) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{5}{10}[/tex]

Since the first marble is not returned, we have the following marbles left

[tex]Blue = 4[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 9[/tex]

The probability of picking a second blue marble is:

[tex]P(B_2) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{4}{9}[/tex]

So, the required probability is:

[tex]P(B_1\ and\ B_2) = P(B_1) * P(B_2)[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5}{10} * \frac{4}{9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5*4}{10*9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{20}{90}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Answer:

1.   2x + 8y = 10xy

2.   13ab + 15ab = 28ab

Step-by-step explanation:

  This is because for question 2 the "a" and "b" stay together since it's on 13 and 15. So that is why you would get 28ab. For question 1 it's basicly the same but instead, you combine the two to get your answer.

CHEEEEESEEEEEEEEEE

Answer:

x/121 + y/9 = 1

Step-by-step explanation:

The major axis is 22 units long, in a horizontal line, and the center is in the middle of the major axis line segment. The center is at the origin. The distance of the whole axis is 22, and its endpoints are 11 units from the center. The axis length is 2a = 22, so a = 11.

Becasue the major axis is horizontal, this ellipse is wider than it is tall.

The minor axis is perpendicular to the major axis and it always shoter (hence the name 'minor'). In this case, it is vertical, is 6 units long, so we say that 6 = 2b, and b = 3.

The ellipse center is (h,k). But in this case, the center is the origin, so h = 0 and k = 0.

The equation for a horizontal ellipse is (x-h)²/a² + (y-k)²/b² = 1, a>b

(x-0)²/11² + (y-0)²/3² = 1

*** x/121 + y/9 = 1

The equation for a vertical ellipse is (x-h)²/b² + (y-k)²/a² = 1, a>b

If the bigger denominator is under 'x' term the ellipse is horizontal, with the longer axis being horizontal.

If the bigger denominator is under the 'y' term, the ellipse is vertical, with the longer axis being vertical.

I'm including 2 files.

The 'brainly ellipse' is form this particular problem.

Discount:

20% is .2 as a decimal, so you multiply the value of 12 by .2

The discount is $2.40

Sale Price:

subtract 2.4 from the price of the original price

12-2.4=9.6

Answer:

Each can of soda will cost $0.37

Step-by-step explanation:

First you write 24/8.99 = 1/x because you are trying to find the cost for 1 soda

24/8.99 = 1/x

Then you cross multiply.

24*x  8.99*1

24x=8.99

Divide each side by 24

24x/24=8.99/24

x=0.374583

Round it to the nearest hundredths place.

x=0.37
