Tyrese wants to buy baseball cards. They cost $5.00 per pack. There is a 25% discount before tax if 10 or more packs are purchased. Sales tax is 7%. If Tyrese buys 15 packs of cards, how much does he pay?
Answer:
72.225 $
Step-by-step explanation:
The price per pack: 5.00 $
When the amount of packs is > 10 :
90 % * 5 $ = 4.50 $ before tax.
The price of 15 packs:
4.50 $ * 15 = 45 + 22.5 = 67.5 $ before tax.
After tax:
107 % * 67.5 $ = 72.225 $ after tax.
The product of
two integers is – 24. The difference
between the two integers is 14. The sum of
the two integers is 10. What are the two
integers?
Answer:
a= 12
b=-2
Step-by-step explanation:
12 x -2 = -24
12 - (-2) = 14
12 + (-2) = 10
The two integers are 12 and -2.
What are simultaneous equation?In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Let x and y be the two integers.
So it is given that,
Product of two integers = – 24
⇒ xy = - 24 ....(i)
The difference between the two integers = 14
⇒ x - y = 14 ...(ii)
The sum of the two integers = 10
⇒ x + y = 10 ....(iii)
Now adding equation (ii) and (iii) we get,
2x = 24
⇒ x = 12
Putting the value of x in equation (i) we get,
12y = - 24
⇒ y = - 2
So the required integers are 12 and - 2.

Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.
- 8 < x , thus
x > - 8
Answer:

You rent an apartment that costs $1400 per month during the first year, but the rent
is set to go up $180 per year. What would be the monthly rent during the 5th year of
living in the apartment?
The rent in the 5th year is $2120.
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. We can find the amount regularly increasing by using arithmetic.
As per the given data:
Cost of the apartment per month during the first year is given, also the increase in rent every year is given.
We have to find out the monthly rent during the 5th year of living in the apartment.
For finding out the monthly rent during the 5th year of living in the apartment:
Rent in first year + Increase in rent in each year × (5 - 1)
= 1400 + 180 × 4
= 1400 + 720
= $2120
The rent in the 5th year is $2120.
Hence, The rent in the 5th year is $2120.

Use a product of two binomials to find a polynomial that represents the area of Roberto's plot.
Answer:
First, we know that the area of a rectangle of width W and length L is:
A = W*L
In the case of Roberto's plan, we can see that the length of the whole rectangle is:
L = 1.5ft + x + 1.5ft = 3 ft + x
And the width is:
W = 3ft + x + 3ft = 6ft + x
Then the area of the whole thing is:
A = (3ft + x)*(6ft + x)
This is what we wanted, a product of two polynomials that represents the area of Roberto's plot.
Now if we subtract the white square (is a square of sidelength x, then its area is A = x*x) we will get the area of the border;
The total area of Roberto's borders is:
Area of the border = (3ft + x)*(6ft + x) - x*x
= 3ft*6ft + 3ft*x + x*6ft + x^2 - x^2
= x*9ft + 18ft^2

Y=
Answer:
y = 210,000(1.055)^t
Step-by-step explanation:
Initial population: p = 210,000
Annual growth rate: 5.5% = 0.055
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 210,000(1 + 0.055)^t
y = 210,000(1.055)^t
Please help!!! The function d= 16t2 models the distance d, in feet, that an object falls in t seconds.
Find the inverse function and use the inverse function to estimate the time it takes an
object to fall 100 feet.
The inverse function is t = d/4
The time the object falls is 5 seconds.
The inverse function is t = d/16
The time the object falls is 0.625 seconds.
The inverse function is t = d/4
The time the object falls is 2.5 seconds.
The inverse function is t = d/16
The time the object falls is 6.67 seconds.

Answer:
24ft²
Step-by-step explanation:
divide up the shape:
big triangle:
(looking for base)
9.8²= 4² + b²
b = 8.95ft
(finding area)
0.5*8.95*4 = 17.9ft²
small triangle:
(looking for base)
12-8.95=3.05ft

0.5*3.05*4 = 6.1ft²
Whole Shape:
17.9+6.1 = 24ft²
A bag contains 40 red and green marbles. The number of green marbles, g, is 9 times the number of red mapples, . How many red marbles are in the bag? O 4 O 6 O 34 O 36
Answer:
4
Step-by-step explanation:
You need to try out all the numbers.
lets start with 4
if there where 4 red marbles then there would be 9 times as many marbles
so 4 x 9 = 36
Now we add and see if the sum is 40
36 + 4 = 40
We got it on the first try

A 45-45-90 triangle has a leg of length 5.38. What is the length of the other leg?
Answer:
5.38 units
Step-by-step explanation:
Because of the base angle theorem converse, This triangle is an isosceles triangle.
Because this is an isosceles triangle, because the leg of the triangle is 5.38 units, that means the other leg has to be 5.38 units
You may be asking, how do I know it's the other leg that's congruent.
Well, the angle opposite to the 90° angle is the hypotenuse, and we want the line segment opposite of the 45° angle. And both the legs are opposite to the 45° angles.
