The number that has 3 hundreds, 4 more tens than hundreds, and 1 more one than hundreds is 374.

The student is asking us to construct a number based on place value criteria. To assemble this number, we will assign the digits to their appropriate places based on the given conditions. Three hundreds means the hundreds place must be 3, so we have '3' in the hundreds place. Since there are 4 more tens than hundreds, we add 4 to 3, giving us 7, which becomes the digit in the tens place. Lastly, there is 1 more one than hundreds, meaning we need to add 1 to 3 to get 4 for the ones place. Therefore, our number is 374, as it meets all the conditions: 3 hundreds, 7 tens (which is 4 more than the hundreds), and 4 ones (which is 1 more than the hundreds).

Answer:

The amount of money which she earn as commission after selling the house is $ 10,740 .

Step-by-step explanation:

Given as :

The selling price of the Mrs. Miller house = $ 179, 000

The percentage of commission which she earn = 6 % of the selling price

Let the amount of money she earn = $ x

Now, According to question

The amount of money she earn = 6 % of the selling price of house

I.e the amount of money she earn = [tex]\frac{6}{100}[/tex]×$ 179,000

Or, the amount of money she earn = 6 × 1790

∴ The amount of money which she earn as commission = $ 10,740

Hence The amount of money which she earn as commission after selling the house is $ 10,740 . Answer

Mrs. Miller earns a commission of $10,740 on selling a house for $179,000.

To solve this problem, we need to calculate 6% of $179,000. The commission amount can be found by multiplying $179,000 by 6% (or 0.06). So, the commission earned by Mrs. Miller would be $179,000 * 0.06 = $10,740. Therefore, Mrs. Miller earns $10,740 as her commission.

Answer:

Number of necklaces sold

Step-by-step explanation:

Every necklace sold becomes added up to make up y, and then you multiply that by $10(the money for necklaces).

Answer:

l = 48(1/4) = 12 cm

w = 20(1/4) = 5 cm

Length: 48 cm

Width: 20 cm

The length of the smaller rectangle is 12 cm, which is one-quarter of the length of the original figure. Therefore, the length of the original figure is 12 cm * 4 = 48 cm.

The width of the smaller rectangle is 5 cm, which is one-quarter of the width of the original figure. Therefore, the width of the original figure is 5 cm * 4 = 20 cm.

The value of "y" is 3

Given that,

[tex]y+\frac{4}{12}-y-\frac{1}{12}=\frac{y}{2}[/tex]

We have to solve for "y"

Let us simplify the given expression and solve for"y"

[tex]y+\frac{4}{12}-y-\frac{1}{12}=\frac{y}{2}[/tex]

On cross multiplication in L.H.S we get,

[tex]\frac{12 y+4-12 y-1}{12}=\frac{y}{2}[/tex]

Cancelling denominator 12 from both sides, we get

12y + 4 -12y - 1 = y

Again cancelling +12y and -12y we get

4 - 1 = y

y = 3

Thus the value of "y" is 3

Answer:

7,920,000

Step-by-step explanation:

The question is asking the number of times that 4 inches fits in 500 miles. We need to divide 500 miles by 4 inches, but first we need to convert 500 miles into inches.

12 inches = 1 foot

5280 ft = 1 mile

500 miles * (5280 ft)/(1 mile) * (12 in.)/(1 ft) = 31,680,000 inches

Now that we know that 500 miles is the same as 31,680,000 inches, we divide that number of inches by 4 inches.

(31,680,000 inches)/(4 inches) = 7,920,000

Answer: 7,920,000

Answer:

10^7

Step-by-step explanation:

So we would start with 10 and a trick to help you is when your turning a number with 10 at the start with each number you raise it by is how many 0 it will have behind it for example 10,000,000 would be 10^7 cause you have 0 zeros in it.

10,000,000 in exponent form is 10⁷. Therefore, 20,000,000 can be written as 2 × 10⁷. This provides a concise mathematical way of expressing large numbers.

To write 10,000,000 using exponents, we recognize that this number is a power of 10. Specifically, 10,000,000 can be written as 10 to the power of 7. This is because:

10,000,000 = 10⁷

When you multiply 10 by itself 7 times (10 × 10 × 10 × 10 × 10 × 10 × 10), you get 10 million. Therefore, the population of Australia, which is more than 20,000,000 people, can be written as:

20,000,000 = 2 × 10,000,000 = 2 × 10⁷

To find the base and height of a parallelogram with an area of 48 square miles, apply the formula Area = Base x Height and then solve for the base and height values using the given area. In this case, the base and height would be 6 miles and 8 miles, respectively.

Explanation:

To find the base and height of a parallelogram, you can use the formula: Area = Base x Height. Given that the area is 48 square miles, and the parallelogram formula, you can find the base and height by solving the equation.

Given: Area = 48 square miles

Formula: Area = Base x Height

The base and height would be 6 miles and 8 miles, respectively.

Answer:

C = 20 + 25h ..... Required identity

(C - 20) = 25(h - 0) ..... Point-slope form

C = 25h + 20 ..... Slope-intercept form.

25h - C = - 20 .... Standard form.

Step-by-step explanation:

A landscaper charges customers a one time fee and an hourly rate of $25.

If for 3 hours of work, it charges $95.

Then, C = C' + 25h ......... (1)  

Where C is the total charge, C' is the fixed charge and h is the number of hours he works.  

Therefore, putting C = $95 and h = 3, we get from equation (1),

95 = C' + 75  

⇒ C' = 20

Therefore, the equation (1) becomes C = 20 + 25h

Hence, this is the identity in the scenario. (Answer)

Now, the point-slope form of the equation is (C - 20) = 25(h - 0)

where slope is 25 and the point is (0,20).

Now, C = 25h + 20

is the slope-intercept form having slope 25 and y-intercept 20.

Now, the standard form of the equation is 25h - C = - 20 (Answer)  

In an ordered pair for a Cartesian coordinate system, the input is represented by the x-axis. It is denoted as the first value in an (x, y) pair and represents the horizontal direction in a two-dimensional space.

In an ordered pair, the input is typically represented by the x-axis in a Cartesian coordinate system. An ordered pair is denoted as (x, y), where 'x' represents the input or independent variable, and 'y' represents the output or dependent variable. For instance, in a function such as y = mx + b, 'x' would be the input and 'y' would be the output. This input value corresponds to the position along the horizontal x-axis.

While the y-axis represents the vertical direction or output value, the x-component of a vector is a dot product with the unit vector in the x-direction. For two-dimensional vector problems, it's also easier to pick a coordinate system that has one horizontal axis (x) and one vertical axis (y), projecting the vectors onto these axes.

Final answer:

In an ordered pair (x, y), the x-axis represents the input which is the horizontal direction on the Cartesian coordinate system.

Explanation:

In an ordered pair, such as (x, y), the x-axis represents the input, which is the horizontal direction, and the y-axis represents the output, which is the vertical direction. In the Cartesian coordinate system, the origin, where the x and y axes intersect, is the point of projection.

By convention, the positive x-axis generally extends to the right, and the positive y-axis extends upwards. The x-coordinate corresponds to the position along the x-axis while the y-coordinate corresponds to the position along the y-axis.

OPTION C: (1,7)

Step-by-step explanation:

The two equations are:

[tex]$ x - y = -6  \hspace{25mm} ....(1) $[/tex]

[tex]$ 5x + 3y = 24 \hspace{25mm} ...(2) $[/tex]

To solve these two equations, multiply (1)  by 5 and subtract (1) and (2).

Therefore, we get the value of y.

[tex]$ y = \frac{54}{8} $[/tex]

This is approximately equal to 7.

Substituting y = 7 in (1), we get x - 7 = -6

⇒ x = -6 + 7

∴ x = 1

So, we say the approximate solution to the equations is: (1,7).

In other words, the two lines meet approximately at (1,7).

Answer:

137.5° and 42.5°

Step-by-step explanation:

supplementary angles are two angles whose sum is equal to 180°.

Let the second angle be x then it is given that the first angle is 10 degrees more than 3 times second angle that is 3(x)+10°.

we know that the sum of first and second angles is 180° (supplementary angles)

so, (3(x)+10°)+(x) = 180°

                   4(x) = 170°

                       x = 170°/4 = 42.5°

so, first angle is 3(42.5°)+10° = 137.5°, second angle is x that is 42.5°

therefore, the angles are 137.5° and 42.5°.
