Step-by-step explanation:
they way it is written, she has one of the best paying jobs in the world : $1470 per hour ...
but I guess it is really $14.70 per hour, right ?
that is then her basic wage : $14.70 per hour for 40 hours = 14.7 × 40 = $588.
her overtime rate is then 14.7×1.25 (one time and a quarter) = 18.375 ≈ $18.38
and she gets that rate for all hours beyond the basic 40 hours, so, 52-40 = 12 hours.
12×18.38 = $220.56
or if you need it totally precise
12×18.375 = $220.50
in total, her gross wage for that week is then
588 + 220.56 = $808.56
or totally precise with unrounded hourly rates
588 + 220.5 = $808.50
which would create a mean hourly rate
808.56/52 = $15.54923077... per hour ≈ $15.55 per hour
or
808.5/52 = $15.54807692... per hour ≈ $15.55 per hour
many payroll systems do the rounding of the hourly rates and then calculate the total amount (as the first option here). some others keep the full decimal positions in the calculation and then only round the total (as the second option here).
so, it is the question what your teacher expects here. I cannot tell from the description.

Answer:
x = 9
Step-by-step explanation:
10 + x/3 = 13
x/3 = 13 -10
x/3 = 3
x = 3*3 = 9
Answer:
9
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions
~
First, subtract 10 from both sides of the equation:
[tex]\frac{x}{3} + 10 = 13\\\\\frac{x}{3} + 10 (-10) = 13 (-10)\\\\\\\frac{x}{3} = 13 - 10\\\\\\\frac{x}{3} = 3[/tex]
Next, isolate the variable, x, by multiplying 3 to both sides of the equations:
[tex](\frac{x}{3}) * 3= (3) * 3\\\\x = 3 * 3\\\\x = 9[/tex]

Sarah has 150 marbles. Of the marbles, 2/5 are blue, 3/10 are clear, and the rest are green. What is the ratio of blue marbles to clear marbles to Green marbles in simplest form?
Answer:
4 : 3 : 3
Step-by-step explanation:
2/5 of 150 = 300/5 or 60; therefore, there are 60 blue marbles
3/10 of 150 = 450/10 or 45; therefore, there are 45 clear marbles
150 - (60 + 45) = number of green marbles; there are 45 green marbles
Blue : Clear : Green ratio is 60 : 45 : 45 or 4 : 3 : 3

how much is 75 decreased by 8% ???
Answer:
69
Step-by-step explanation:
The number 75 decreased by 8% means that you are looking for 92% of 75. To find a percent of the number you can multiply a number by the percent in decimal form. So, to find 92% of 75, multiply 75*0.92. This gives you 69. Doing this is the same as finding 8% of 75 and then subtracting.

You want to save at least $180 to buy a new phone. You already have $65 in your account, and you can save $23 a week from your after-school job. Which inequality can be used to find the minimum number of weeks you need to save before you can purchase the phone?
Answer: 180≤23x+65
Step-by-step explanation:
p = phone
w = weeks
65 + 23w ≥ 180
If you need it to be solved, the minimum number of weeks goes as shown:
65 + 23w ≥ 180
-65 -65
23w ≥ 115
/23 /23
w ≥ 5
So, the minimum number of weeks that is required is 5.

Solve the pair of simultaneous equations
x = 4 - y
x = y + 2
(3,1)
x=3; y=1
Step-by-step explanation:
Algebraic
Answer:
The solution to this system of linear equations is (3, 1).
Step-by-step explanation:
Here we have two equations for x. We can eliminate x by setting these two equations equal to one another, obtaining 4 - y = y + 2, or 2 = 2y
Then y must be 1. Substituting this into the first equation, we get x = 4 - 1 = 3.
The solution to this system of linear equations is (3, 1).

it's AAS is my opinion
Step-by-step explanation:
Answer:
AAS
Step-by-step explanation:
we can eliminate two of the answer choices from the start. AA and SSA do not prove triangle congruence. we are then left with SAS and AAS. we can see that there is one pair of sides and one pair of angles marked congruent on the triangles. the triangles are formed by intersecting lines which form vertical angles. according to the vertical angles theorem, those two angles will be congruent. therefore, these triangles are proven congruent by AAS. hope this helps!
Work out m and c for the line:3x + 2y−1 =0
please help quickly
Answer:
m=-1.5 and c=0.5
Step-by-step explanation:
3x+2y-1=0
divide everything by 2, to get y.
3x/2=1.5x, -1/2=-0.5.
then separate 1.5x and -0.5 from y (put them on the other side)
there, y=-1.5x+0.5
m=-1.5, and c=0.5
23% of a snack mix is almonds. How much snack mix would you need to get 230g of almonds?
Answer:
230/p = 23/100 You would need 1,000 g of snack mix.
Step-by-step explanation:
There are 1000 snack mix would be needed to get 230g of almonds.
Given that;
23% of a snack mix is almonds.
And, there are 230g of almonds.
Let us assume that;
The number of snacks = x
Hence, it can be written as,
23% of x = 230
23/100 × x = 230
23x = 23000
x = 23000/23
x = 1000
Therefore, The number of snacks = 1000 g

Two cars A and B 250 km apart are traveling towards each other on the same road. Car A travels at 55 km/h
while car B travels at 70 km/h.
(a) When will they meet on the road?
(b) Find the distance each car travels before they meet.
Answer:
At 2 hours they will meet on the road
Car A: 110 km; Car B: 140 km
Step-by-step explanation:
Since the total distance is 250 km, we know that when the sum of the miles driven by each car adds to 250, they will meet.
Let x be the time, in hours.
Miles Travelled
Car A (55km/h)x
Car B (70 km/h)x
(55km/h)x + (70 km/h)x = 250
55x + 70x = 250
125x = 250
x = 2 hours At 2 hours they will meet on the road
Distance Travelled
Car A (55km/h)2 = 110 km
Car B (70 km/h)2 = 140 km
Prove the following:

Answer:
a. 3/10
b. 1/10
c. 4/10 or 2/5
Step-by-step explanation:
There is 4 brown, 3 green, 2 red, and 1 purple if you add those all up you get 10. Since there is a total of 10 marbles in the bag and 3 of those are green 3/10 of the marbles are green. Same goes with purple, 1 of the 10 marbles in the bag is purple.
To solve for green and purple you must add them. Since there is 3 green and 1 purple that gives you 4. 4 out of 10 marbles are green or purple. 4/10 can also be simplified to 2/5
Given h(x)=-3x-4h(x)=−3x−4, find h(0)
Answer:
h(0) = -4
Step-by-step explanation:
Put the value where the variable is and do the arithmetic.
h(x) = -3x -4
h(0) = -3·0 -4 = 0 -4
h(0) = -4
_____
Additional comment
In general, a polynomial function evaluated when the variable is zero will have the value of any added constant. All of the variable terms will be zero. Since the constant in this function is -4, we know immediately that h(0) = -4.

Jane wrote all the natural numbers from 5 to k. including 5 and k
how many numbers did Jane write?
need help!!!
Given that "Jane wrote all the natural numbers from 5 to k. Including 1 and k"
So Jane wrote k numbers.
lets take an example
if k = 10 , then natural numbers between 1 and 10 are 10 numbers that are 1 , 2 , 3 ,4 ,5 ,6 , 7 , 8 ,9 and 10.
Hence she write k numbers.
Jane wrote k - 4 natural numbers for the given condition.
What are natural numbers?Natural numbers are defined as which range from 1 to infinity and are the most fundamental sort of numbers. Commonly known as positive numbers or counting numbers, these numbers. Natural Numbers are represented by the symbol N.
Jane wrote all the natural numbers from 5 to k, including 5 and k.
So, she wrote the numbers as 5, 6, 7, 8, 9, ..., k.
To find out how many numbers Jane wrote, we have to subtract 4 from each of these numbers because 4 numbers (1, 2, 3, 4) come before 5.
1, 2, 3, 4, 5, ..., k-1
So, there are k-1 - 4 + 1 = k - 4 natural numbers between 5 and k, inclusive.
Therefore, she wrote k - 4 natural numbers.
