Answers

Answer 1

Answer:

30, +11, 11, -1

Step-by-step explanation:

-10 + 30 = 10, 40 - 30= 10

-3 + 11 = 8

5 + (1.5 x 4) = 11

5 - (1.5 x 4) = -1

Answers

Answer:

5x^2 +4x -6

Step-by-step explanation:

that is the answer

yep

Answer:

5x² + 4x - 6

Step-by-step explanation:

Subtract 2x² - 5x - 12 from 7x² - x - 18 , that is the opposite operation, that is

7x² - x - 18 - (2x² - 5x - 12) ← distribute parenthesis by - 1

= 7x² - x - 18 - 2x² + 5x + 12 ← collect like terms

= 5x² + 4x - 6

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 in how many years should he pay the remaining amount with total interest of 20000 from the beginning?​

Answers

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

the measure of an interior angel of a regular polygon is 150. find the number of sides in the polygon.

Answers

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!

elena bikes 20 minutes each day for exercise write and equation to describe the relationship between her distance in miles d and her biking speed in miles per hour when she bikes at a constant speed of 15 miles per hour for the first 5 minutes then at 12 miles per hour for the last 15 minutes

Answers

Answer:
The equation to describe the relationship between Elena distance:
a) D = 4.34 miles, b) D = 4.25 miles and c) 12D = M + 3N miles.
Solution:
Given, Elena bikes 20 minutes each day for exercise.
We have to write an equation to describe the relationship between her distance in miles, D, and her biking speed, in miles per hour,
We know that, distance travelled = speed time
a. At a constant speed of 13 miles per hour for the entire 20 minutes
Her speed is 13 miles per hour.
Then, distance D miles = 13 miles per hour 20 minutes

b. At a constant speed of 15 minutes per hour for the first 5 minutes, then at 12 miles per hour for the last 15 minutes
Now, total distance travelled = distance travelled with 15 mph + distance travelled with 12 mph

c. At a constant speed of M miles per hour for the first 5 minutes, then at N miles per hour for the last 15 minutes
Now, total distance travelled = distance travelled with M mph + distance travelled with N mph



Hence, a) D = 4.34 miles, b) D = 4.25 miles and c) 12D = M + 3N miles.

A rectangle has a perimeter of 6x^3+ 9x^2 - 10x + 5 and a length of x. Find the width of the rectangle when
the length is 21 inches.

Answers

Answer:

59330 feet

Step-by-step explanation:

If length is equal to 21 feet, then x=21

Width will be f(21)=6*(21)^3+9*(21)^2-210+5=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.

What is the perimeter of a rectangle?

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.

9. x is directly proportional to y. When x = 4, y = 9. Write an equation
for y in terms of x.

Answers

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
