Step-by-step explanation:

Let x = the number of muffins

x*3/4 = 21

Multiply each side by 4/3

Answer:

659 units

Step-by-step explanation:

The length of the segment is the distance between the points.

The distance between two points on the number line is the absolute value of the difference between their coordinates. It does not matter in which order you subtract the numbers.

One point has coordinate 225.

Another point has coordinate -434.

Subtract one coordinate from the other and take the absolute value of the difference.

distance = |-434 - 225| = |-659| = 659

Answer: 659 units

Length of given line segment is 659 units

Step-by-step explanation:

Given:

First point plotted on number line = 225

Second point plotted on number line = - 434

Find:

Length of line segment

Computation:

Length of line segment = Distance between two point

(Distance between two point will be added as absolute value)

So,

Length of line segment = |-434| + |225|

Length of line segment = 434 + 225

Length of line segment =  659 units

Answer:

59330 feet

The width of the rectangle with the given perimeter and length is 29,686 inches.

Given that, the perimeter of a rectangle = 6x³+ 9x² - 10x + 5 and length=x.

We need to find the width of the rectangle when the length is 21 inches.

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Let the width of the rectangle be y.

Now, length=x=21 inches.

Thus, 6x³+ 9x² - 10x + 5 = 2(x+y)

⇒6×21³+ 9×21² - 10(21)+ 5=2(21+y)

⇒55,566+3,969-210+5=42+2y

⇒59,372=2y

⇒y=29,686 inches

Therefore, the width of the rectangle with the given perimeter and length is 29,686 inches.

Step-by-step explanation:

a money account works in the same way as real things we can touch.

so, when I have 300 apples at a place (e.g. a grocery store), then I take away 300 apples, and then put again 300 apples there - how many apples will be there at that moment ?

we had 300 and took away 300.

300 - 300 = 0

at that moment we have 0 apples.

but then we put again 300 apples there.

0 + 300 = 300

so, we end up with 300 apples. the same number we started with.

and the same way for the savings account.

he takes out $300.

that means he has now $300 less on his account.

and then he adds $300.

so, he added exactly the same amount as he took out earlier, which means nothing else than that he undid his earlier action regarding his bank account.

so, his balance is now exactly the same as before he did the first transaction.

therefore the change is exactly : $0

Answer:

y = 2.25x

Step-by-step explanation:

Given x is directly proportional to y then the equation relating them is

x = ky ← k is the constant of proportion

To find k use the condition when x = 4, y = 9 , then

4 = 9k ( divide both sides by 9 )

[tex]\frac{4}{9}[/tex] = k

x = [tex]\frac{4}{9}[/tex] y ← equation of proportion

Multiply both sides by [tex]\frac{9}{4}[/tex] to clear the fraction

[tex]\frac{9}{4}[/tex] x = y , then

y = [tex]\frac{9}{4}[/tex] x , or

y = 2.25x

Using the fundamental counting principle, it is found that there are 84 different paths.

-----------------------------

Fundamental counting principle:

States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.

The movements are independent, which means that the fundamental counting principle is used.

Ramesh took a loan of rs 50000 from Urmila at the rate of 10%p.a. if he paid half of the principal and all the interest at the end of 3 years

P= 80000

R = 10% '

1st-year amount = 88000

10% compounded annually

If you pay the loan of  55000 at the end of year 2, constant payment from year 1 After that, I paid 110% of the balance. C. I have always calculated in terms of the previous year's amounts

= \frac{55000}{110} \times 100 = 50000

So after the first year, a certain amount is paid, and the remaining amount is will be 50000.

So a certain amount to be paid in 1 year = 88000 -50000 = 38000

Answer:

The polygon has [tex]12[/tex] sides.

Step-by-step explanation:

Recall that the expression for finding the measure of one interior angle of a regular polygon is [tex]\frac{180(n-2)}{n}[/tex], where [tex]n[/tex] is the number of sides the polygon has (and [tex]n\neq 0[/tex]), which is what we want to find.

Because the measure of one interior angle of the given polygon is [tex]150\textdegree[/tex], we can write the following equation to solve for [tex]n[/tex]:

[tex]\frac{180(n-2)}{n}=150[/tex]

Solving for [tex]n[/tex], we get:

[tex]\frac{180(n-2)}{n}=150[/tex]

[tex]\frac{180n-360}{n}=150[/tex] (Distribute the [tex]180[/tex] in the numerator)

[tex]180n-360=150n[/tex] (Multiply both sides of the equation by [tex]n[/tex] to eliminate the denominator and simplify)

[tex]30n-360=0[/tex] (Subtract [tex]150n[/tex] from both sides of the equation and simplify)

[tex]30n=360[/tex] (Add [tex]360[/tex] to both sides of the equation to isolate [tex]n[/tex] and simplify)

[tex]\bf n=12[/tex] (Divide both sides of the equation by [tex]30[/tex] to get rid of [tex]n[/tex]'s coefficient and simplify)

Therefore, the polygon has [tex]\bf 12[/tex] sides. Hope this helps!
