Answer:

Order from least degree to highest degree

15xy - 89y², 7x³ + 5y, 2x³y + 5x²

Step-by-step explanation:

For polynomials, the degree a polynomial has can be defined as the highest number of power a variable in that polynomial carries.

From the above question, we are asked to arrange this polynomials from least to highest

Hence:

7x³ + 5y , -2x³y + 5x², 15xy - 89y²

Order from least degree to highest degree

15xy - 89y², 7x³ + 5y, 2x³y + 5x²

∠A and angle B∠ are complementary angles. if m∠A=(4x+6)

miss Akunina [59]

Answer:

m∡A = 50°

Step-by-step explanation:

since they are complementary they must equal 90°

4x+6 + 4x-4 = 90

8x + 2 = 90

8x = 88

x = 11

∡A = 4(11)+6 = 44+6 = 50

10. The perimeter of a regular nonagon is 162 inches. The apothem is 97.8 inches. Find the area.

Katen [24]

Answer:

The area of the regular nonagon is 7921.8 square inches.

Step-by-step explanation:

Geometrically speaking, the area of a regular polygon is determined by following area formula:

$A = \frac{p\cdot a}{2}$ (1)

Where:

$A$ - Area of the regular polygon, in square inches.

$p$ - Perimeter, in inches.

$a$ - Apothem, in inches.

If we know that $p = 162\,in$ and $a = 97.8\,in$ , then the area of the regular nonagon is:

$A = 7921.8\,in^{2}$

The area of the regular nonagon is 7921.8 square inches.

Monica paid sales tax of $3.20 when she bought a new bike helmet. If the sales tax rate was 8%, how much did the store charge fo

ICE Princess25 [194]

Answer: the store charged $40 for the bike helmet before tax.

Step-by-step explanation:

Let x represent the amount that the store charge for the bike helmet before tax.

If the sales tax rate was 8%, it means that the amount of tax that was charge is

8/100 × x = 0.08 × x = 0.08x

Monica paid sales tax of $3.20 when she bought a new bike helmet. This means that

0.08x = 3.2

Dividing the left hand side and the right hand side of the equation by 0.08, it becomes

0.08x/0.08 = 3.2/0.08

x = 40
