When the bases are the same, you can combine the exponents.
x³ [x is where the base is]
For example:
x³ · y² = x³y² You can't simplify this anymore because they have different bases/variables
[when you multiply a variable with an exponent by a variable with an exponent, you add the exponents together] so:

lizzy gets her paycheck every 10 days. Her husband, Don gets a paycheck every 14 days. On July 3, they both get a paycheck. How many days will pass before they both get check on same day
5 weeks .... 35 days
Lizzy and Don will both receive their paychecks on the same day after 70 days, as 70 is the Least Common Multiple (LCM) of their paycheck intervals of 10 and 14 days.
Lizzy and Don are trying to find out when they will both receive their paychecks on the same day again. To solve this, we need to find the Least Common Multiple (LCM) of their paycheck intervals which are 10 days for Lizzy and 14 days for Don. The LCM of 10 and 14 is the smallest number that both 10 and 14 can divide into without leaving a remainder.
Let's list the multiples of each:
Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, ...
Multiples of 14: 14, 28, 42, 56, 70, 84, 98, 112, ...
The smallest common multiple they share is 70. This means that after 70 days, both Lizzy and Don will receive their paychecks on the same day again.
5x < 45
please help
ANSWER
[tex]x \: < \: 9[/tex]
EXPLANATION
The given inequality is
[tex]5x \: < \: 45[/tex]
We divide through by 5 to get:
[tex]x \: < \: \frac{45}{5} [/tex]
This will simplify to
[tex]x \: < \: 9[/tex]
Therefore the solution to the inequality is
[tex]x \: < \: 9[/tex]
x < 9
Start with 5x < 45.
Divide both sides of the inequality by 5 to get x < 45 / 5, or x < 9.

Anne bought 3 hats for $19.50. which equation could be used to find the cost of each equation?
Answer:
19.50 divided by 3
Step-by-step explanation:
Answer:
3h = 19.50
Step-by-step explanation:
First lets define the price of each hat as the variable h.
Next we know that there are 3 hats so we can write that variable as 3h
We also know that the cost of all 3 hats was $19.50. This means that we can set each side of this equation equal to each other.
This gives us the equation 3h = 19.50
If you were to solve for h, you would get
[tex]h = \frac{19.50}{3}[/tex]
Which would simplify to
h = 6.50
This means that each hat costs $6.50
What is the name of a polygon that has four congruent sides and these angle measures 80,100,80,100
Quadrilateral. If you add the angles up on any quadrilateral, it equals 360 (it should always add to 360 for a quadrilateral)
The polygon you're describing is a kite.
To verify this, let's calculate the sum of the interior angles of the polygon:
Sum of interior angles = [tex](n - 2) * 180 degrees[/tex]
For a polygon with 4 sides: [tex](4 - 2) * 180 = 360 degrees[/tex]
Now, let's add up the given angle measures: 80 + 100 + 80 + 100 = 360 degrees
Since the sum of the interior angles matches the calculated sum for a four-sided polygon, and the sides are congruent, the polygon is indeed a kite.
1. Calculate the sum of interior angles: The sum of interior angles of any polygon can be found using the formula (n - 2) * 180 degrees, where 'n' represents the number of sides. For a four-sided polygon, the sum is (4 - 2) * 180 = 360 degrees.
2. Add up the given angle measures: The given angle measures are 80, 100, 80, and 100 degrees. Adding them together gives a total of 360 degrees, which matches the sum calculated for a four-sided polygon.
3. Confirming the polygon type: Since the sum of the interior angles matches the calculated sum for a four-sided polygon, and the sides are congruent (meaning all sides have the same length), the polygon fits the definition of a kite.
Therefore, the polygon with four congruent sides and angle measures of 80, 100, 80, and 100 degrees is indeed a kite.

Radius BE is a perpendicular bisector of chord AC. What is the measure of
A. 100°
B. 50°
C. 90°
D. 40°
Answer:
A. 100
Step-by-step explanation:
50 + 50 + 100
Answer:
A. 100°
Step-by-step explanation:
Let's take a look at the image and make some conclusions.
Angle BAE is 40 degrees
All angles at the crossing of BE and AC are right angles (90 degrees) because they are perpendicular lines.
Since BE is a bisector of angle ABC, we know that angles ABD and DBC are equal.
We don't know angle ABD but it's easy to find... since we know 2 angles from triangle ABE, and the sum of the interior triangles is 180. So,
ABD = 180 - 40 - 90 = 50
Since ABD is 50 degrees and represents half of angle ABC... we know that ABC is 100 degrees.
two lines are intersecting what is the value of x
Answer:
[tex]x=111[/tex]
Step-by-step explanation:
Since these angles are supplementary, they add up to 180°.
Let's make an equation.
[tex]360=(x+23)+(2x+4) \\ \\ 360=x+23+2x+4 \\ \\ 360=3x+27 \\ \\ 3x=333 \\ \\ x = 111[/tex]
Answer:
[tex]x=51[/tex]
Step-by-step explanation:
We have been given an image of two intersecting lines. We are asked to find the value of x.
We can see that both angles are supplementary, so we can set an equation as:
[tex]x+23+2x+4=180[/tex]
[tex]x+2x+4+23=180[/tex]
[tex]3x+27=180[/tex]
[tex]3x+27-27=180-27[/tex]
[tex]3x=153[/tex]
[tex]\frac{3x}{3}=\frac{153}{3}[/tex]
[tex]x=51[/tex]
Therefore, the value of x is 51.

Answer:
the sine of angle R is 5/7.
Step-by-step explanation:
Recall that the sine function is defined as sin Ф = (opposite side) / hypotenuse.
The side opposite Angle R is √65 and the hypotenuse is √91.
Thus, the sine of angle R is sin R = √65 / √91, or 5/7.
find all zeros: f(x)=x^3-2x^2-4x+8
To find all zeros of f(x) = x^3 - 2x^2 - 4x + 8, we can use the Rational Root Theorem to test possible rational roots. The only rational root is x = 2. The complex roots can be found by dividing the equation by (x - 2) and solving the resulting quadratic equation.
Explanation:To find all zeros of the equation f(x) = x^3 - 2x^2 - 4x + 8, we can use the Rational Root Theorem to test possible rational roots. By factorizing the constant term, 8, and the leading coefficient, 1, we find that the possible rational roots are ±1, ±2, ±4, ±8. By testing these values in the equation, we can find that the only rational root is x = 2. To find the complex roots, we can use polynomial long division or synthetic division to divide the original equation by (x - 2) and solve the resulting quadratic equation.

find 2 different ways to make the addition problem work. each letter stands for the same digit 0 to 9 whenever it is used
The addition problem can be solved in two ways: treating each column separately without carrying and writing down the sum of each column even if it is 10 or more. Examples demonstrate each method using single-digit addition without carrying and adjusting sums that exceed single digits.
Explanation:The question at hand involves solving a unique addition problem where each letter corresponds to a digit between 0 and 9. To find 2 different ways to make the addition problem work, we need to apply traditional addition rules along with the clues provided.
First, let's analyze the given examples:
42 + 59 equals 911 - This suggests that each digit is added independently, without carrying over to the next column. Adding 2 and 9 gives 11, placed in the units column. 4 and 5 give 9, placed in the tens column.23 + 54 equals 77 - This result follows the standard addition rules with carrying over.To construct two solutions, let's use the same principle:
For the first way, treat each column separately without carrying. For example, 35 + 46 would equal 711 (5+6 = 11 and 3+4 = 7).For the second way, consider a different interpretation where numbers in each column that add up to 10 or more result in just writing down the sum. For instance, 85 + 78 would equal 1513 (5+8 = 13, and 8+7 = 15).It's important to follow the instructions closely and understand that digits in these sum calculations are handled independently based on the context provided.

Step-by-step explanation:
In the triangle ABC , AB=17cm,BC=9cm and angle ACB=90°
Calculate AC
I believe the answer is 14.42
The length of AC is 14.42 in the triangle ΔABC where AB=17cm, BC=9cm and angle ∠ACB=90°. This can be obtained by using Pythagoras' theorem.
What is Pythagoras' theorem?Pythagoras' theorem states that the sum of squares of the legs of a right triangle is equal to the square of the hypotenuse, that is,⇒ a² + b² = c²Calculate the side AC of ΔABC:Given that, AB=17cm, BC=9cm and angle ∠ACB=90°.
By using Pythagoras' theorem,
AB² = AC²+BC²
17² = AC²+9²
AC² = 17²-9² =289-81 = 208
AC = √208 =14.42
⇒AC = 14.42cm
Hence the length of AC is 14.42 in the triangle ΔABC where AB=17cm, BC=9cm and angle ∠ACB=90°.

Answer:
the answer is 1,194
Step-by-step explanation:
what you want to do is find the area of 2 triangles and 3 rectangles
area of 1st rectangle
1 = ae
=(22 ft) (19 ft)
=418 sq. ft.
area of 2nd rectangle
2 = ab
=(22 ft.) (14 ft.)
=308 sq. ft.
area of 3rd rectangle
3=ad
=(22 ft.) (13 ft.)

Solve this system of linear equations. Separate the x- and y-values with a comma. -3x=42-16y 14x=76-16y
To solve the given system of linear equations -3x = 42-16y and 14x = 76-16y, use the method of elimination to find the solution (20-6y, y).
Explanation:To solve the system of linear equations -3x = 42-16y and 14x = 76-16y, we can use the method of substitution or elimination. Let's use the method of elimination:
Multiply the first equation by 2 to make the coefficients of y in both equations equal. The equations become:
-6x = 84-32y and 14x = 76-16y
Add the two equations together:
-6x + 14x = 84-32y + 76-16y
Simplify:
8x = 160-48y
Rearrange the equation to solve for x:
x = (160-48y)/8
Simplify further:
x = 20-6y
The solution to the system of equations is x = 20-6y. To separate the x- and y-values, we write it as (20-6y, y).
