Ethan will subtract a 3-digit number

from 920. He says the difference could be a 1-digit

number, a 2-digit number, or a 3-digit numbens

Write three subtraction equations that show each

difference. Be sure you start with 920 and subtract a

3-digit number each time

Answers

Final answer:

Subtracting smaller 3-digit numbers from 920 results in 3-digit answers, subtracting larger 3-digit numbers gives 2-digit answers, and subtracting even larger 3-digit numbers results in 1-digit answers. Examples include: 920 - 120 = 800, 920 - 825 = 95, and 920 - 915 = 5.

Explanation:

This question involves simple subtraction operations. Here are three subtraction equations that meet the conditions:

For a 3-digit result: 920 - 120 = 800. Here, subtracting a 3-digit number (120) from our original number (920) results in a 3-digit number (800). For a 2-digit result: 920 - 825 = 95. In this case, subtracting a bigger 3-digit number (825) leaves us with a 2-digit number (95). For a 1-digit result: 920 - 915 = 5. Subtraction of an even larger 3-digit number (915) results in a 1-digit number (5).

As we increase the 3-digit number that we subtract from 920, the result decreases in the number of digits,

Final answer:

To subtract 3 digit numbers from 920 and end up with a 1-digit, 2-digit or 3-digit number, the following equations are provided: 920 - 911 = 9, 920 - 815 = 105 and 920 - 100 = 820.

Explanation:

To find three subtraction equations that show the difference when subtracting a 3-digit number from 920, we need to consider all possible scenarios for the difference.

The smallest possible difference would be a 1-digit number.

To get a 1-digit number, 2-digit number, or a 3-digit number as the result while subtracting a 3-digit number from 920, here are three equations:

• The smallest possible difference would be a 1-digit number. 920 - 911 = 9

• The next possible difference would be a 2-digit number. 920 - 815 = 105

• The largest possible difference would be a 3-digit number. 920 - 100 = 820

In each equation, we started with 920 and subtracted a 3-digit number. Given that the numbers we subtract are less than 920, it becomes possible to get a 1-digit, 2-digit, or 3-digit result.

A cylinder with height 10 inches and radius 4 inches is filled with water. The water is poured into a bowl

will fit, tell how much empty space remains in the bowl. If all the water will not fit, tell how much water is left in
the cylinder. (leave your answer in terms of pi)

Answers

Answer:

Volume of water left in the cylinder=[tex]76\frac{2}{3}\pi \:in^3[/tex]

Height of the Cylinder=10 inches

Radius of the cylinder=4 Inches

Volume of the Cylinder

Radius of the Hemisphere=5 Inches

Which equation represents the line
3x - 2y = -8 in slope-intercept
form?

Answers

Answer:

The slope -intercept form of the equation is;

y = [tex]\frac{3}{2}[/tex]  x  +   4

Step-by-step explanation:

The slope-intercept form of an equation is;

y = mx + c

where m is the slope and c represent the intercept

To represent the equation given; 3x - 2y = -8 in its slope intercept form, we will follow the steps below:

3x - 2y = -8

subtract 3x from both-side of the equation

3x - 3x -2y  = -3x - 8

-2y = -3x -8

Divide throught the equation by -2

-2y/-2 =-3x/-2  -8/-2

y = [tex]\frac{3}{2}[/tex]  x  +   4

The slope -intercept form of the equation is;

y = [tex]\frac{3}{2}[/tex]  x  +   4

Angle 1 is 100 degrees. What is the measure of angle 3?

Answers

Answer:

Angle 3 is also 100

Step-by-step explanation:

They are vertical angles and vertical angles are always congruent.

The angle 3 is in the given figure is ∠3 = 100°.

What are parallel lines?

The parallel lines are a group of straight lines that never intersect with one another. The distance between two parallel is always the same.

The measure of angle 1 is given as ∠1 = 100°.

When two lines intersect each other, the pair of vertically opposite angles are equal.

Since, angle 1 and angle 3 are vertically opposite, they are equal.

Thus, ∠3 = 100°.

Hence, the measure of angle 3 is 100°.

A cash register contains $10 bills and $100 bills with a total value of $2010. If there are 30 bills total, then how many of each does the register contain? $10 bills

Answers

Answer:

there will be 19 $100 bills

and 11 $10 bills

Step-by-step explanation:

[tex]100*19=1900\\10*11=110\\1900+110=2010[/tex]

Answer:

11

Step-by-step explanation:

Let x be how many $10 bills there are.

Let y be how many $100 bills there are

x + y = 30

x = 30 - y

10x + 100y = 2010

10(30 - y) + 100y = 2010

300 - 10y + 100y = 2010

-10y + 100y = 2010 - 300

90y = 1710

y = 1710 / 90

y = 19

x = 30 - 19

x = 11

3.5(2.25 + x) = 14

Answers

Answer:

1.75

Step-by-step explanation:

Use the distributive property first.

(3.5 x 2.25) (3.5 x X) = 14

7.875 + 3.5x = 14   Now subtract 7.875 from both sides

3.5x = 6.125  Now divide 3.5 by both sides

x = 1.75

Final answer:

The equation 3.5(2.25 + x) = 14 is solved by first distributing 3.5 through the parentheses, then isolating x on one side, yielding a result of x = 1.75.

Explanation:

In this mathematical equation, the first step is to distribute 3.5 to (2.25 + x). The result is 7.875 + 3.5x = 14. We then subtract 7.875 from both sides to isolate the term with x which gives 3.5x = 6.125. Finally, to solve for x, we divide both sides by 3.5. This gives us x = 1.75.

There are 3 less than twice as many cats than dogs in the local animal shelter. If there are 210 cats and
dogs combined, how many dogs are in the animal shelter?

Answers

There are 71 dogs in the local animal shelter.

To determine the number of dogs and cats in the shelter, let's denote the number of dogs by D and the number of cats by C. According to the problem statement, there are twice as many cats as dogs, minus three. Mathematically, this is represented as C = 2D - 3. We also know that the combined total of cats and dogs is 210, which can be expressed as C + D = 210. To find the number of dogs, we can solve these two equations simultaneously.

From the first equation, we solve for C in terms of D: C = 2D - 3.

Substitute C into the second equation: (2D - 3) + D = 210.

Combine like terms: 3D - 3 = 210.

Add 3 to both sides of the equation: 3D = 213.

Divide both sides by 3 to solve for D: D = 71.

Therefore, there are 71 dogs in the local animal shelter.

As we can see in the graph, the points:

P is located at (-2, 8)Q is located at ( 6, 8) R( is located at (6, 2) S is located at (-5, 0)

To find a distance between two points or the length of the segment, we use the following formula:

[tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

Because the two points P and Q are located at the same libe y = 8

=> the lenght of PQ = [tex]\sqrt{(6- (-2))^{2} } = \sqrt{8^{2} } = 8\\[/tex]

Because the two points R and Q are located at the same libe x = 6

=>  the length of RQ = [tex]\sqrt{(8-2)^{2} } = \sqrt{6^{2} } = 6\\[/tex]

The lenght of RS is: [tex]\sqrt{(-5-6)^2+(0-2)^2} = \sqrt{-11^{2} +(-2)^{2} }[/tex] = [tex]\sqrt{125} = 11.1[/tex]

The lenght of SP is: [tex]\sqrt{(-5-(-2))^2+(0-8)^2} = \sqrt{-3^{2} +(-8)^{2} } = \sqrt{73}[/tex] = 8.5
