Answer:

2.899

Step-by-step explanation:

The formula for calculating the distance between two points P(x1, y1) and (x2, y2) is expressed as:

D = √(x2-x1)²+(y2-y1)²

Given the points (2,-2) and (1,x) and the distance between the point as 5, we are to get x. To get x we will substitute the points and the distance given into the formula.

Given x1 = 2, y1 = -2, x2 = 1, y2 = x and D = 5

On substitution:

5 = √(1-2)²+(x-(-2))²

5 = √1²+(x+2)²

5 = √1+(x+2)²

Square both sides of the equation

5² = (√1+(x+2)²)²

25 = 1+(x+2)²

(x+2)² = 25-1

(x+2)² = 24

Square both sides

√(x+2)² = √24

x+2 = √24

x = √24- 2

x = 4.899-2

x = 2.899

Hence the other value is 2.899

Answer:

1.) Time in minutes

2.) Distance in feet.

Step-by-step explanation:

What is the independent quantity?

Independent quantity are the domain. In this question since the rate is 400 feet per minute, this can be refer to slope.

The independent quantity is therefore the time in minutes.

What is the dependent quantity?

Dependent quantity depends on independent quantity. Since time is the independent quantity, distance in feet will be the dependent quantity.

Answer:

[tex]\sqrt{x}[/tex]

Step-by-step explanation:

If we have that worded expression, we can convert it into actual mathematical terms.

x to the one sixth power: [tex]x^{\frac{1}{6}}[/tex]

That to the power of 3:

[tex](x^{\frac{1}{6}})^3[/tex]

Using exponent rules, since we have a power to a power, the powers multiply, so:

[tex]x^{\frac{1}{6}\cdot 3}\\\\x^{\frac{3}{6}}\\\\ x^{\frac{1}{2}}[/tex]

If we have a number to a fraction power, the denominator becomes the “find the (denominator) root of x.

So:

[tex]x^{\frac{1}{2}} = \sqrt{x}[/tex]

Answer:

The correct option is;

C. Domain: {9, 10, 11, 12}; range {22, 32, 41, 30}

Step-by-step explanation:

The given parameters are;

The ticket sold at the talent show for different grades;

For grade 9, 22 tickets were sold

Grade 10, had 32 tickets sale

The number of tickets sold for grade 11 = 41 tickets

The number of tickets sold for grade 12 = 30 tickets

We note that the domain are the inputs and independent variables, x, of a function,f(x), while the range is the set of outputs, dependent, variables,  of the function or the values of f(x)

Therefore, given that the domain are the independent variable, that is their values are not influenced by other variables, then the domain are the grades, which are 9, 10, 11, 12, while the range are the range are the number of tickets sold (22, 32, 41, 30) which are dependent on the grades

Answer:

(2x + 1)(x + 4)

Step-by-step explanation:

2x² + 9x + 4 cannot be factored normally - we must use the grouping technique (a > 1).

First, check for a GCF. Because there is not a GCF within this (factors of 9 are 1 and 3 - taking a 1 out is pointless), we will instead break the equation into two factors.

2x² will be apart of the first factor. You want to break the 9x into factors that will evenly break down with the 2x^2, so 3x will not work.

Your grouping factors should then be (2x^2 + 8x)(x + 4).

Then, take out the GCFs of the factors.

2x can come out of (2x^2 + 8x), so your new factor is 2x(x + 4). Your second factor set has no GCF, so you take out a 1 and get 1(x+4). In order to verify you did this correctly, the terms having the GCF distributed cannot be different in anyway.

Your factors are now (2x + 1)(x + 4) take the two GCFs and make them a factor set, then the second factor is the common factor.

Step-by-step explanation:

Answer:

[tex]x=11[/tex]

Step-by-step explanation:

So we have the equation:

[tex]\frac{-2-2x}{3} =-8[/tex]

First, multiply both sides by 3. This cancels out the denominator:

[tex]3(\frac{-2-2x}{3} )=3(-8)[/tex]

The left side cancels. Multiply the right:

[tex](-2-2x)=-24[/tex]

Add 2 to both sides. The 2s on the left cancel:

[tex](-2-2x)+2=(-24)+2\\-2x=-22[/tex]

Divide both sides by -2. The -2 on the left cancel.

[tex](-2x)/-2=(-22)/-2\\x=11[/tex]

Therefore, the answer is 11.

Answer:

x = 11

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

*(-2-2*x)/(3)-(-8)=0

Simplify:

*-2 - 2x  / 3

Pull out like factors:

*-2 - 2x  =   -2 • (x + 1)

Now It should look like this:

-2 • (x + 1) / 3 - (-8)  = 0

Rewrite the whole as a equivalent fraction using 3 as the denominator:

*-8 = -8 / 1 = -8 • 3 / 3

Add the two equivalent fractions which now have a common denominator

-Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

*-2 • (x+1) - (-8 • 3) / 3 = 22 - 2x / 3

Pull out like factors:

*22 - 2x  =   -2 • (x - 11)

Now you should have this:

*-2 • (x - 11)  / 3  = 0

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

-Now, to get rid of the denominator, multiply both sides of the equation by the denominator.

*-2•(x-11)  / 3 • 3 = 0 • 3

-Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

Now you should have this:

*-2  •  (x-11)  = 0

Now Solve:

x-11 = 0  

-Add  11  to both sides of the equation:

x = 11

Answer:

6 yards long

Step-by-step explanation:

1/3 yards wide = 2 yards long

Let x = length of the other rug

1 yard wide = x yards long

1/3 : 2 = 1 : x

1/3 ÷ 2 = 1 ÷ x

1/3 × 1/2 = 1 / x

1/6 = 1/ x

Cross product

1*x = 6*1

x= 6 yards

Therefore, the length of the new rug with 1 yard wide is 6 yards long

The first thing to do is to find the ratio of wide to long of the two rugs by representing the long of the second rug with x

Option C: x = 300

Step-by-step explanation:

Step 1. Expand the brackets.

When factorising (putting into brackets) and expanding (taking out of brackets), it is always important to remember that the number on the outside multiplies everything on the inside. It is also important to remember the signs of the outside and inside numbers (i.e. if the numbers are positive or negative).

[tex]\frac{1}{3}[/tex](x - 15)

= ([tex]\frac{1}{3}[/tex] × x) - ([tex]\frac{1}{3}[/tex] × 15)

= (x ÷ 3) - (15 ÷ 3)

= [tex]\frac{x}{3}[/tex] - 5

Step 2. Solve the equation.

[tex]\frac{x}{3}[/tex] - 5 = 95

What we want to do is to get x on its own on one side, so that we can figure out the value of x.

[tex]\frac{x}{3}[/tex] - 5 = 95

+ 5 to both sides (do the opposite of what is there, [tex]\frac{x}{3}[/tex] is subtracting 5 right now, but we want to cancel that subtraction out, so we do the opposite of subtraction, i.e. addition)

[tex]\frac{x}{3}[/tex] = 95 + 5

[tex]\frac{x}{3}[/tex] = 100

× 3 to both sides (do the opposite of what is there: x is divided by 3 right now, but we want to cancel that division out, so we do the opposite of division, i.e. multiplication)

[tex]\frac{x}{3}[/tex] x 3 = 100 x 3

x = 100 x 3

x = 300

Step 3. We look for out answer within the options given.

As we can see, the option of [x = 300] is option C, so the answer we would give would be "C".

Answer:

11.3 cm

Step-by-step explanation:

The diagonal d divides the square into 2 right triangles with legs 8 and hypotenuse the diagonal d.

Using Pythagoras' identity in one of the right triangles, then

d² = 8² + 8² = 64 + 64 = 128 ( take square root of both sides )

d = [tex]\sqrt{128}[/tex] ≈ 11.3 cm

Answer:

[tex]\huge\boxed{c = 11.3 cm}[/tex]

Step-by-step explanation:

Using Pythagorean Theorem:

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

Where  c is the length of diagonal and a and b are the sides of the square

[Remember that all sides of the square are equal]

=> [tex]c^2 = 8^2 + 8^2[/tex]

=> [tex]c^2 = 64+64\\[/tex]

=> [tex]c^2 = 128[/tex]

Taking sqrt on both sides

Answer:

1035

Step-by-step explanation:

(2.3 × 10^4)(4.5 × 10^6)

First we do the exponents:

10^-4 = 0.0001

10^6 = 1,000,000(1 mil)

Now we plug them into the equation:

(2.3 × 0.0001)(4.5 × 1,000,000)

Now we multiply the numbers in the paranthesis:

(0.00023)(4,500,000) = 0.00023 × 4,500,000

Now we multiply both of them:

0.00023 × 4,500,000 = 1035

Answer:

School to library = 875 feet

School to train station = 1000 feet

School to town hall = 1125 feet

Step-by-step explanation:

School to library: 3.5 cm

Since 2 cm is equal to 500 feet, then 1 cm is equal to 250 feet.

3.5 cm = 250 (3.5) = 875 feet.

School to train station: 4 cm

4cm = 4 (250) = 1000 feet.

School to town hall: 4.5 cm

4.5 cm = 4.5 (250) = 1125 feet.
