Answer:

scale factor = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Given

A(4, - 2 ) → A'(1, - [tex]\frac{1}{2}[/tex] )

To determine the scale factor compare the ratio of corresponding coordinates, image to original, that is

scale factor = [tex]\frac{1}{4}[/tex] = [tex]\frac{-\frac{1}{2} }{-2}[/tex] = [tex]\frac{1}{4}[/tex]

Answer: This was confusing, but I think I get it.? Your answer is 800,000

Step-by-step explanation: 80,000 x 10 = 800,000

Answer:

SO we have to solve this equation:

24p + 12 - 18p = 10 + 2p - 6

First, we will operate what we have in both sides:

24p - 18p + 12 = 10 - 6 + 2p

6p + 12 = 4 + 2p

We substract 2p in both sides and 12 too.

6p + 12 - 2p - 12 = 4 + 2p - 2p - 12

4p = -8

Now, we divide both sides by 4

4p/4 = -8/4

p = -2

The value of p is -2.

The correct option is (B)

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

24p +12 - 18p = 10 + 2p - 6

Now, solving for p

6p + 12= 2p + 4

6p - 2p = 4 -12

4p = -8

p= -8/4

p= -2

Hence, the value of p is -2.

[tex]\frac{\sqrt{3}}{11}>\frac{\pi }{24}>\frac{3}{25}>\frac{9}{100}[/tex]

Step-by-step explanation:

To get the order of the lengths in the order from greatest to least we will make the denominator of the given fractions common and then compare the numerators.

[tex]\frac{3}{25}, \frac{\sqrt{3}}{11}, \frac{9}{100},\frac{\pi }{24}[/tex]

LCM of the denominators,

2 |  25   11    100   24

2 |  25    11     50    12

5 |  25    11     25     6  

5 |    5     11     5      6  

      1      11      1       6

LCM = 2×2×5×5×6×11 = 6600

[tex]\frac{3}{25}=\frac{3}{25}\times \frac{264}{264}[/tex]

   [tex]=\frac{792}{6600}[/tex]

[tex]\frac{\sqrt{3}}{11}=\frac{\sqrt{3} }{11}\times \frac{600}{600}[/tex]

    [tex]=\frac{600\sqrt{3}}{6600}=\frac{1039}{6600}[/tex]

[tex]\frac{9}{100}=\frac{9}{100}\times \frac{66}{66}[/tex]

     [tex]=\frac{594}{6600}[/tex]

[tex]\frac{\pi }{24}=\frac{\pi }{24}\times \frac{275}{275}[/tex]

    [tex]=\frac{275\pi }{6600}[/tex]

    [tex]=\frac{864}{6600}[/tex]

Now we can arrange these fractions in the order of greatest to least.

[tex]\frac{1039}{6600}>\frac{864}{6600}>\frac{792}{6600}>\frac{594}{6600}[/tex]

Answer:

[tex]q=33[/tex]

Step-by-step explanation:

So we have:

[tex]3=\frac{q}{11}[/tex]

Multiply both sides by 11:

[tex]11(3)=(11)\frac{q}{11}[/tex]

The right side cancels:

[tex]11(3)=q[/tex]

Multiply the left:

[tex]33=q[/tex]

Thus, the value of q is 33.

Answer:

q = 33

Step-by-step explanation:

3 = q/11 multiply both side by 11

3 * 11 = [tex]\frac{q}{11}[/tex] * 11

33 = q

Answer:

its called a Domain

Step-by-step explanation:

All of the x-values or inputs are called Domain.

"x-values" is the word used in mathematics and statistics to describe the input values or independent variables in a function or equation.

These x-values stand for a function's inputs, arguments, or the points at which a mathematical connection is being assessed.

The outputs or dependent variables of a function are represented by the appropriate y-values, which are often paired with the associated x-values. The link between the independent and dependent variables can be seen on a graph by plotting the x-values and y-values together as data points.

For example, in the equation y = 2x + 3, "x" represents the x-values or inputs, while "y" represents the corresponding y-values or outputs. By substituting different values for x, you can calculate the corresponding y-values and observe how changes in the x-values affect the relationship described by the equation.

Hence the answer is Domain.

Answer:

0 is the answer

Step-by-step explanation:

The position of point P is at 0 on number line.

What is Number line?

Number line is a straight line with numbers placed at equal intervals.

Given that;

Point C is located at -4.

Point D is located at 6.

Now,

Distance between points -4 and 6 is,

6 - (-4) = 6 + 4 = 10

Since, Point P be located so that the directed line segment from C to D will be partitioned in a 2 : 3.

Let partitions are 2x and 3x.

Then,

2x + 3x = 10

5x = 10

x = 2

So, The partitions between point C and D is,

2x = 2 × 2 = 4

3x = 3 × 2 = 6

So, The ratio become = 4 : 6

Thus, Position of point P from C = - 4 + 4 = 0

Position of point P from D = 6 - 6 = 0

So, The position of point P is at 0 on number line.

110 miles ................. 5 hours

176 miles ..................x hours

x = 176×5/110 = 880/110 = 8 hours

Answer:

maya drives 110 miles in 5 hours. If she continued at the same rate, how long would it take to travel 176 miles?

We use the rule of three

110 miles -------------> 5 hours

176 miles ------------> ???

So (176 miles × 5 hours) /110 miles

We simplify by 《miles》 because it is in the numerator and the denominator

SO (176×5 hours )/110

= 880 hours / 110

= 8 hours

So she drives 176 miles in 8 hours.

Step-by-step explanation:

If we assume that the combination of green and pink means, 1 green and 1 pink, then we can say the following:

P = 1 / 25 + 1 / 25

P = 2 / 25

This is because the squares where green and pink intersect only occurs twice.

Answer:

x = 18

Step-by-step explanation:

Solve for x:

15 (x - 20) - 21 = 6 - 3 (x + 1)

Hint: | Distribute 15 over x - 20.

15 (x - 20) = 15 x - 300:

15 x - 300 - 21 = 6 - 3 (x + 1)

Hint: | Group like terms in 15 x - 300 - 21.

Grouping like terms, 15 x - 300 - 21 = 15 x + (-300 - 21):

15 x + (-300 - 21) = 6 - 3 (x + 1)

Hint: | Evaluate -300 - 21.

-300 - 21 = -321:

15 x + -321 = 6 - 3 (x + 1)

Hint: | Distribute -3 over x + 1.

-3 (x + 1) = -3 x - 3:

15 x - 321 = -3 x - 3 + 6

Hint: | Group like terms in -3 x - 3 + 6.

Grouping like terms, -3 x - 3 + 6 = (6 - 3) - 3 x:

15 x - 321 = (6 - 3) - 3 x

Hint: | Evaluate 6 - 3.

6 - 3 = 3:

15 x - 321 = 3 - 3 x

Hint: | Move terms with x to the left hand side.

Add 3 x to both sides:

15 x + 3 x - 321 = (3 x - 3 x) + 3

Hint: | Look for the difference of two identical terms.

3 x - 3 x = 0:

15 x + 3 x - 321 = 3

Hint: | Group like terms in 15 x + 3 x - 321.

Grouping like terms, 15 x + 3 x - 321 = (15 x + 3 x) - 321:

(15 x + 3 x) - 321 = 3

Hint: | Add like terms in 15 x + 3 x.

15 x + 3 x = 18 x:

18 x - 321 = 3

Hint: | Isolate terms with x to the left hand side.

Add 321 to both sides:

18 x + (321 - 321) = 321 + 3

Hint: | Look for the difference of two identical terms.

321 - 321 = 0:

18 x = 3 + 321

Hint: | Evaluate 3 + 321.

3 + 321 = 324:

18 x = 324

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 18 x = 324 by 18:

(18 x)/18 = 324/18

Hint: | Any nonzero number divided by itself is one.

18/18 = 1:

x = 324/18

Hint: | Reduce 324/18 to lowest terms. Start by finding the GCD of 324 and 18.

The gcd of 324 and 18 is 18, so 324/18 = (18×18)/(18×1) = 18/18×18 = 18:

d = 81

Step-by-step explanation:

Solve for d:

36 = (4 d)/9

Hint: | Reverse the equality in 36 = (4 d)/9 in order to isolate d to the left hand side.

36 = (4 d)/9 is equivalent to (4 d)/9 = 36:

(4 d)/9 = 36

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (4 d)/9 = 36 by 9/4:

(9×4 d)/(4×9) = 9/4×36

Hint: | Express 9/4×4/9 as a single fraction.

9/4×4/9 = (9×4)/(4×9):

(9×4)/(4×9) d = 9/4×36

Hint: | Express 9/4×36 as a single fraction.

9/4×36 = (9×36)/4:

(9×4 d)/(4×9) = (9×36)/4

Hint: | Cancel common terms in the numerator and denominator of (9×4 d)/(4×9).

(9×4 d)/(4×9) = (4×9)/(4×9)×d = d:

d = (9×36)/4

Hint: | In (9×36)/4, divide 36 in the numerator by 4 in the denominator.

36/4 = (4×9)/4 = 9:

d = 9×9

Hint: | Multiply 9 and 9 together.

9×9 = 81:

Answer: d = 81

Answer: d=81

Step-by-step explanation:

Given

36=4/9 d

Divide both sides by 4/9 (division property of equality)

d=36 ÷ (4/9)

Turn division of fraction into multiplication of its reciprocal

d=36 × (9/4)

Simplify

d=81
