Sheila is a manager at the Adam's Mark hotel and has a yearly salary of $65,500. If Sheila pays
21% in taxes and gets paid on the 15th and last day of the month, how much is each paycheck?
Show your work.
Answer:
$2139.58
Step-by-step explanation:
First, you find how much each paycheck is worth with taxes excluded, since she is only keeping 79% of the money you multiply 65,000 by 0.79=51350. Since she is getting paid twice a month, she is getting 24 paychecks a year. So you diving 51350 by 24 to get 2139.58333 but round down to 2139.58
On a certain hot summer's day, 435 people used the public swimming pool. The daily prices are 1.25 for children and 2.00 for adults. The receipts for admission totaled 818.25 How many children and how many adults swam at the public pool that day?
The number of children and the number of adults that swam in the swimming pool that day are 69 and 366 respectively.
Given that:-
Total number of people that swam in the swimming pool = 435
Price for children = 1.25
Price for adults = 2
Total receipts = 818.25
We have to find the number of children and the number of adults that swam in the swimming pool that day.
Let the number of children that swam that day be x and,
the number of adults that swam that day be y.
Hence, we can write,
1.25x + 2y = 818.25 ...(1)
x + y = 435 ... (2)
Solving the linear equation in two variable by elimination method
Multiplying (2) by 2 , we get
2x + 2y = 870 ... (3)
(3) - (1)
0.75x = 870 - 818.25
0.75x = 51.75
x = 51.75/0.75
x = 69
From (2), we can write,
69 + y = 435
y = 435 - 69
y= 366
Hence, the number of children and the number of adults that swam that day are 69 and 366 respectively.

A number written as a superscript over another number is known as an exponent. In other words, it means that the base has been elevated to a particular level of power. Other names for the exponent are index and power. The way to express huge numbers in terms of powers is to multiply them by themselves n times, or mn, if m is a positive number and n is its exponent. An exponent is a sign that is printed above and to the right of a mathematical expression to indicate the action of raising to a power. Exponent, then, is the number of times a number has been multiplied by itself. For instance, the number 6 is multiplied by itself four times, yielding 6 6 6 6. This might be the number 64.

Find the unknown measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.
The unknown measures of the right angle triangle are m∠V = 69° , RV = 12.85 and m∠R = 21°
How to find the angles and side of a right triangle?A right triangle is a triangle that has one of its angles as 90 degrees.
Therefore, the side and angles of a right triangle can be found using trigonometric ratios.
Hence,
tan v = opposite / adjacent
opposite side = 12
adjacent side = 4.6
Therefore,
tan V = 12 / 4.6
v = tan⁻¹ 2.60869565217
v = 69.0265065627
m∠V = 69°
Let's find m∠R
m∠R = 180 - 69 - 90
m∠R = 21°
Let's find RV
sin 69° = opposite / hypotenuse
sin 69 = 12 / h
cross multiply
h = 12 / sin 69
h = 12 / 0.93358042649
h = 12.8537402885

a nursery decides to make a grass-seed blend by mixing rye seed that sells for $6.50 per pound with bluegrass seed that sells for $3.50 per pound. the final mix is 180 pounds and sells for $5.33 per pound. how much of each type was used?
The amount of rye seed and bluegrass seed used in the mixture is 109.8 and 70.2 pounds respective.
What exactly is the substitution method?The substitution method is an algebraic approach to solving simultaneous linear equations.As the name implies, the value with one variable from one equation is replaced in the other equation.In response to the given question;
Let's say the amount of rye seed is 'x.'
The cost of rye seed = $6.50 per pound
Let's say the amount of bluegrass seed is 'y.'
The cost of bluegrass seed = $3.50 per pound.
The total seeds are 180 pounds.
Thus,
x + y = 180
x = 180 - y .......eq 1.
The other equation for the total cost of $5.33 per pound is;
6.50x + 3.50y = 5.33×180
Put the value of x from eq 1.
6.50(180 - y) + 3.50y = 959.4
1170 - 6.50y + 3.50y = 959.4
3y = 210.6
y = 70.2
x = 180 - 70.2 = 109.8
Thus, the amount of rye seed and bluegrass seed used in the mixture is 109.8 and 70.2 pounds respectively.
