Answer:

[tex]\frac{25}{15}[/tex] is greater.

Step-by-step explanation:

25÷15=1.67

2÷3=0.67

1.67 is greater than 0.67, so [tex]\frac{25}{15}[/tex] is greater.

Also,  [tex]\frac{25}{15}[/tex] is an improper fraction, and  [tex]\frac{2}{3}[/tex] is a proper fraction. Improper fraction mast be greater than a proper fraction.

Answer:

the point is (1.73, 3)

Step-by-step explanation:

Given a vector on an xy plot, the magnitude is the hypotinuse of the triangle formed, and the direction is the angle with x axis. So we have a right angle triangle that must be a 30-60-90 (sum = 180).

Then from the lower angle

sin(60) = opposite/hypotinuse = y/(2*3**(1/2))

0.866 = y/(2*1.732)

0.866 = y/3.464

0.866 * 3.464 = y

3 = y

Then from the top angle

sin(30) = opposite/hypotinuse = x/(2*3**(1/2))

sin(30) = x/(2*3**(1/2))

0.5 = x/(2*3**(1/2))

0.5 = x/3.464

0.5 * 3.464 = x

1.73 = x

Answer: First Choice. 5ft

Step-by-step explanation:

Here we need to know the idea of the Pythagorean theorem.

Since a building is straight, the base angle is a right angle, thus it would be a right triangle.

Pythagorean Theorem: a² + b² = c²

**NOTE** Please refer to the attachment below for the figure. (I drew it, so if it was not clear and understandable for you, please tell me.)

Solve:

Given information

a = 12 ft

c = 13 ft

b = unknow base length

Given formula for Pythagorean Theorem

a² + b² = c²

Substitute values into the formula

12² + b² = 13²

Simplify exponents

144 + b² = 169

Subtract 144 on both sides

144 + b² - 144= 169 - 144

b² = 25

Square root both sides

√b² = √25

Answer:

10

Step-by-step explanation:

Given: 20 yards of ribbon in total. Need to make 2 yards each.

To find out how many yards you need to cut, divide:

20 / 2 = 10

So, you need to make 10 cuts for the 20 yards.

Hope this helped.

Answer:

Step-by-step explanation:

2^6  = 64 and the only power of 64 that gives us 1 is 64^0 = 1. S0 x = 1.

Now 5^0 is already 1. Then (5^0)^x =1^x is equal to 1 for any value of x.

by using the pythagoras theorem,

the height of the ladder touching the wall =

√(20²- 4²)

=√ (400-16)

The polynomial in standard form is as follows;

8x⁵  - 5y⁴ - 2xy⁵ + x²y

A polynomial can have constants, variables and exponents, but never division by a variable. example of a polynomial is as follows:

4xy² + 2y + 5

Polynomial can be named base on the number of terms. For example monomial, binomial and trinomial.

The standard form of a polynomial is expressed by writing the highest degree of terms first then the next degree and so on.

Therefore, the polynomial in standard form is as follows;

8x⁵  - 5y⁴ - 2xy⁵ + x²y

Answer and Step-by-step explanation:

When multiplying exponents:

- Product of Powers: When the base of the exponents are the same, and the bases are being multiplied to each other, the exponents are added together.

- Different bases Same Exponents: When the bases of the exponents are different, but the exponents are the same, the bases multiply together (within a parenthesis) with the exponent on the parenthesis.

- Quotient of Powers: When the base of the exponents are the same, and they are being divided by each other, the exponents will subtract from each other.

- Power of a Power: When a base has an exponent, and that entire term has and exponent, the exponents multiply together.

- Power of a Product: The opposite of Different bases Same Exponents. Distribute the exponent onto the different bases.

- Power of a Quotient: The opposite of Quotient of Powers. Distribute the exponent to the dividing bases.

- Zero Power: Any number raised to the 0 power equals 1.

- Negative Exponent: Any number raised by a negative number goes to the denominator of a fraction (if not already in the denominator), and vise versa (goes to the numerator if not already in the numerator).  

- Power of One: Any number raised to the power of 1 is the same number.

..........m.........

Answer:

x=37

Step-by-step explanation:

here,

143+x=180

x=180-143

x=37

3(2x - 1) + 2(x + 5) = 47

6x - 3 + 2x + 10 = 47

6x + 2x = 47 + 3 - 10

8x = 40 / : 8

x = 5 ← the end

Answer:

x = 5
