You are exploring a career in nursing in the state of MA. The average hourly wage for RN is $33.37. You are planning to work 40 regular hours +8 hours overtime at time and a half every week. What were your weekly earnings be?
Answer:
$1,735.24
Step-by-step explanation:
"at time and a half" basically means 1.5
So, the overtime would be 1.5 times the normal hourly wage.
40 regular hours * $33.37 = $1334.8
8 overtime hours * (1.5 * $33.37) = $400.44
$1334.8 + $400.44 = $1735.24
So, the total weekly pay is $1735.24.

If you want to buy an item in a store that cost $43 and is on sale for 40% off, then how much would the item actually cost you after the discount ? round to the nearest cent
Answer:
$25.80
Step-by-step explanation:
40% = 40/ 100 = 4/10 = 0,4
There is a 40% discount, which means that the amount multiplied by more then 1 (for example 1,4) would increase the amount... That isn't right because it is a discount!
So you need to subtract the 40%, so (1 - 0.4 =) 0.6
The amount multiplied by 0.6 will be the correct amount, being $43 * 0.6 = $25.80 (rounded to the nearest cent).
The amount the item actually cost after the discount is $25.80

On a map of a town, a school is located at (–6, 2) and a movie theater is located at (–6, –15). What is the distance from the school to the theater on the map?
Answer:
13 units
Step-by-step explanation:
Since the x-coordinates are the same, you can simply add the absolute value of the y-coordinates.
|2 + (-15)|
or
|2 - 15|
= 13
Therefore, the distance from the school to theater is 14 units.
Answer:
13 units

What are the zeros of (fx) =x^2-10x+25
Answer:
Zero of the function f(x) is x = 5
Step-by-step explanation:
Given function is f(x) = x² - 10x + 25
For zeros or x-intercepts of this function,
Put f(x) = 0
x²- 10x + 25 = 0
x² - 2(5)x + 5² = 0
(x - 5)² = 0 [Since, a² - 2ab + b² = (a - b)²]
x = 5
Therefore, x = 5 will be the zero of the given function.
7) The senior classes at High School A and High School B planned separate trips to
Yellowstone National Park. The senior class at High School A rented and filled 2 vans
and 7 buses with 407 students. High School B rented and filled 1 van and 7 buses with
389 students. Every van had the same number of students in it as did the buses. How
many students can a van carry? How many students can a bus carry?
Answer:
Number of students in each van = 18
Number of students in each bus = 53
Step-by-step explanation:
Given: The senior class at High School A rented and filled 2 vans and 7 buses with 407 students.
High School B rented and filled 1 van and 7 buses with 389 students.
Also, every van and the van had the same number of students in it.
Solution:
Let x denotes number of students in each van and y denotes number of students in each bus.
According to the given information,
[tex]2x+7y=407\,\,\,(i)\\x+7y=389\,\,\, (ii)[/tex]
From (ii), put [tex]x=389-7y[/tex] in (i)
[tex]2(389-7y)+7y=407[/tex]
[tex]778-14y+7y=407\\778-407=7y\\7y=371\\y=\frac{371}{7}=53[/tex]
Put [tex]y=53[/tex] in [tex]x=389-7y[/tex]
[tex]x=389-7(53)\\=389-371\\=18[/tex]
Number of students in each van = 18
Number of students in each bus = 53
A rectangle has a height of 2x^4and a width of x^2+8x+15x
Answer:
2x⁶ + 16x⁵ + 30x⁴
Step-by-step explanation:
area of rectangle with height 2x⁴ and width x²+8x+15
area = height x width
2x⁴( x²+8x+15)
2x⁴( x²) +2x⁴(8x)+ 2x⁴(15)
2x⁴⁺² + 16x⁴⁺¹ + 30x⁴
2x⁶ + 16x⁵ + 30x⁴
the area of the rectangle in polynomial which is in standardised form is 2x⁶ + 16x⁵ + 30x⁴
Question: 5 ( x +20)= 7x +30
Answer:35
Simplifying
5(x + 20) = 7x + 30
Reorder the terms:
5(20 + x) = 7x + 30
(20 * 5 + x * 5) = 7x + 30
(100 + 5x) = 7x + 30
Reorder the terms:
100 + 5x = 30 + 7x
Solving
100 + 5x = 30 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
100 + 5x + -7x = 30 + 7x + -7x
Combine like terms: 5x + -7x = -2x
100 + -2x = 30 + 7x + -7x
Combine like terms: 7x + -7x = 0
100 + -2x = 30 + 0
100 + -2x = 30
Add '-100' to each side of the equation.
100 + -100 + -2x = 30 + -100
Combine like terms: 100 + -100 = 0
0 + -2x = 30 + -100
-2x = 30 + -100
Combine like terms: 30 + -100 = -70
-2x = -70
Divide each side by '-2'.
x = 35
Simplifying
x = 35
Hope it helps. Please tell me if im correct
Answer:
35
Step-by-step explanation:
5 * X= 5x
5* 20=100
these are for the ones inside the pararenthesis
so....
5x + 100= 7x+30
subtract 30 from both sides
5x+100-30= 7x-30-30
5x+70= 7x
now we need the variable on one side
so we subtract 5x on both sides
5x-5x+70= 7x-5x
70= 2x
now we divide by 2 on both to isolate the variable
70/2= 2/2
35=x
that's ur answer
hope this helped :D

Find the zeros of the function. Write the smaller solution first, and the larger solution second f(x)=(x+2)2-16 smaller x larger x
Answer:
The solutions are x = -6 or x = +2
Step-by-step explanation:
In this question, we are asked to get the series of the equation given. we can find this by equating what we have to zero
Mathematically, we proceed as follows;
(x +2)^2 -16 = 0
This can be rewritten as;
(x + 2)^2 - 4^2 = 0
we can then proceed to use the difference of two squares to finish this off
Thus, we have
(x + 2 + 4)(x + 2 - 4) = 0
(x + 6)(x-2) = 0
X + 6 = 0 or x-2 = 0
x = -6 or x = +2
At a summer camp,the ratio of campers to adults is kept equivalent to 7:1 use equivalent ratios to complete the table
Answer:
Campers: 7, 14, 28, 42
Adults: 1,2,5,30
Step-by-step explanation:
The tabular representation of the ratio of campers to adults in the summer camp is given as follows -
CAMPERS : 7 14 21 28 . . . . 7n
ADULTS : 1 2 3 4 . . . . n
We have a summer camp in which the ratio of campers to adults is kept equivalent to 7:1 .
We have to complete the table using the equivalent ratios.
How can you find out the equivalent ratios of the ratio a : b ?To find the equivalent ratios of a : b, follow the simple rule -
[tex]a:b=\frac{a}{b}=\frac{a\times2}{b\times2} =\frac{a\times3}{b\times3} =\frac{a\times4}{b\times4} = ... =\frac{a\times n}{b\times n}[/tex]
In the question given -
[tex]a:b=\frac{7}{1}=\frac{7\times2}{1\times2} =\frac{7\times3}{1\times3} =\frac{7\times4}{1\times4} = ... =\frac{7\times n}{n\times n}[/tex]
Hence, we can write the equivalent ratios in the form of tables -
CAMPERS : 7 14 21 28 . . . . 7n
ADULTS : 1 2 3 4 . . . . n

At their family's pizzeria, Dave makes 6 pizzas in the first hour it is open and 3 pizzas each hour after that. Lauren makes 11 pizzas in the first hour and 3 pizzas each hour after that. If the pizzeria is open for 6 hours, how many pizzas will they make in all?
Answer:
47 pizzas
Step-by-step explanation:
Dave makes 6 pizzas in the first hour it is open and 3 pizzas each hour after that.
If the number of hours after the first hour is represented as x, then the number of pizzas he makes after x hours is:
6 + 3x
Lauren makes 11 pizzas in the first hour and 3 pizzas each hour after that. Then:
11 + 3x
The pizzeria is open for 6 hours in all, that is, 5 hours after the first hour.
This means that:
x = 5
The total amount of pizzas that Dave and Lauren make is:
6 + 3x + 11 + 3x
=> 17 + 6x
Therefore, the total amount of pizza they make 5 hours after the first hour is:
17 + 6(5) = 17 + 30 = 47 pizzas
