Joe earns $425 a week for working 40 hours and an additional $20 an hour for each hour over 40. Last week, Joe made $485. Write

Tasya [4]

Answer:

Joe worked 3 hours overtime.

Step-by-step explanation:

Let t = number of hours overworked

425 + 20 × t = 485

425 + 20t = 485

20t = 485 - 425

= 60

$\frac{20t}{20} = \frac{60}{20}$

t = 3

$\therefore$ Joe worked 3 hours over time.

Hope this helps :)

Which expression is equivalent to <img src="https://tex.z-dn.net/?f=-4x%5E%7B-5%7D%20x%5E%7B0%7D" id="TexFormula1" title="-4x^{-

Ber [7]

The expression that is equivalent to the given expression is -4x^-5

<h3>How to determine which expression is equivalent to the given expression?</h3>

The expression is given as:

$-4x^{-5} x^{0}$

Rewrite properly as

-4x^-5x^0

Express as products

-4x^-5 * x^0

The value of x^0 is 1

So, we have:

-4x^-5 * 1

Evaluate the product

-4x^-5

Hence, the expression that is equivalent to the given expression is -4x^-5

A quarter throws a football from a height of 6.5 feet with an initial velocity of 64 feet per second

ohaa [14]

Answer:

0.10s

Step-by-step explanation:

Given data

DIstance= 6.5ft

velocity = 64 feet per second

with the parameters given above, we can find the time taken as

velocity = distance/time

time= distance/velocity

time= 6.5/64

time= 0.10 seconds

Hence the time the ball took is 0.10s

A circle is inscribed in an equilateral triangle. A point in the figure is selected at random. Find the probability that the poi

liubo4ka [24]

Answer:

The correct answer is first option 60%

Step-by-step explanation:

The radius of a circle is inscribed in an equilateral triangle with side a = a/2√3

<u>To find the area of equilateral triangle</u>

Here side be 'a'

Area of equilateral = √3a²/4

<u>To find the area of circle</u>

Here radius = a/2√3

Area = πr²

= π(a/2√3)

= 3.14a²/12

<u>To find the probability</u>

probability = area of circle/area of triangle

= 3.14a²/12/ √3a²/4

= 3.14/3√3

= 0.6043 ≈ 60.43 % 60 %

The correct answer is first option 60%

Reposting because nobody will help me..

Llana [10]

Answer:

Step-by-step explanation:

18 = 2 * 3 * 3 = 2 *3²

$18*3^{(n+2)} = 2*3^{2}*3^{n+2}\\\\$

$= 2*3^{2+n+2}\\\\= 2*3^{n+4}\\\\= 2(3)^{n+4}$

Hint:

$a^{m}*a^{n} = a^{m+n}$
