Answer:

28 feet

Step-by-step explanation:

20 + 10 = 30 - 2 = 28 feet

The dolphin is 20 feet below the surface, goes down another 10 feet, so 30 feet below the surface, and raises two feet, so 28 feet below the surface.

Answer:

Multiplication comes before division.

Step-by-step explanation:

This abbreviation can be used to easily remember the order of operations: PEMDAS

P - Parenthesis (Bracket)

E - Exponent (^)

M - Multiplication (×)

D - Division (÷)

A - Addition (+)

S - Subtraction (-)

This order should be followed accordingly when solving a mathematical problem so as to find the correct answer.

Answer:

Multiplication comes before division.

Answer:

Move all terms to the left side of the equation and simplify.

4x²+7x−2=0

Use the quadratic formula to find the solutions.

(−b±√b2−4(ac))/2a Substitute the values a=4 , b=7, and c=−2 into the quadratic formula and solve for x.

(−7±√72−4⋅(4⋅−2))/2⋅4 Simplify.

x=−(7±9)/8 .The final answer is the combination of both solutions.

x=1/4,−2

Answer:

The area of the plate is 47.78

Step-by-step explanation:

Given:

Circumference of a circular plate = 24.5 inches.

To FInd:

Area of the circular plate

Solution:

By the formula of circumference

Circumference of a circular plate = 2πr

Where 'r' = radius of the plate

24.5 = 2[tex]\pi r[/tex]

r = [tex]\frac{24.5}{3.14 * 2}[/tex]  [Since π = 3.14]

r = 3.90 inches

We know the formula of a circular plate is,

Area =  πr²

Therefore, A = (3.14)(3.90)²

A = 47.79 square inches

Therefore, area of the circular plate is 47.79 inches.

Answer:

the answer is -1 1/8

Answer:

Zeroes: x=4, x=-1/2, and x=6

Step-by-step explanation:

Use Synthetic Division where x-4=0 to find another factor:

4 | 2 -19 +38 +24

  ___8_-44_-24

    2 -11  -6  |   0

So far, your two factors are x-4 and 2x^2-11x-6.

We can actually factor 2x^2-11x-6 into (2x+1)(x-6), so we have three factors which are (x-4), (2x+1), and (x-6)!

By the Zero Product Property, x=4, x=-1/2, and x=6 are your zeroes.

Answer:

[tex]\sqrt{360}[/tex]

Step-by-step explanation:

Use Pythagorean Theorem:

[tex]a^2+b^2=c^2[/tex]

Plug in a=18 and b=6

[tex]18^2+6^2=c^2[/tex]

Simplify

[tex]360=c^2[/tex]

Thus when you square root both sides, you will get:

[tex]c=\sqrt{360}[/tex]  which is also equivalent to 18.97 or [tex]6\sqrt{10}[/tex]
