Answer:
The Answer is 1 1/8
Step-by-step explanation:
When Stanley ate 3/8 of a pizza and his brother ate 3/4 of a pizza, the amount eaten in all is 1 1/8 of the pizza.
What is a fraction?A fraction simply means a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.
In this case, Stanley ate 3/8 of a pizza and his brother ate 3/4 of a pizza.
Therefore, the amount eaten by both of them will be:
= 3/8 + 3/4
= 3/8 + 6/8
= 9/8
= 1 1/8.
The amount is 1 1/8.

the amount of sales tax paid on a purchase is proportional to the price of the item. suppose the sales tax rate is 6.25%. if p is the price of the item and t is the sales tax, which equation represents this?
The equation which represents the amount is p = 0.0625 t.
When a consumer buys a good or service from a retailer, sales tax, which is estimated as a percentage, is added to the cost of the item.
Sales tax rate = sales tax percent / 100.
Sales tax = list price * sales tax rate.
Total price including tax = list price + sales tax,
Total price including tax = list price + (list price * sales tax rate),
Total price including tax = list price * ( 1 + sales tax rate)
We have been given
sales tax rate = 6.25%.
The price of the item = p
The sales tax = t
We know that the amount of sales tax paid on a purchase is proportional to the price of the item.
p = 6.25% t
p = 6.25/100 t
p = 0.0625 t.
Hence , P = 0.0625 t is the equation used to represent the amount.

(3+√c) (2√c - 3) = 1 + k√c
where c and k are prime numbers.
(a) Find the value of c and the value of k.
Answer:
c = 5
k = 3
Step-by-step explanation:
We have the expression:
(3+√c) (2√c - 3) = 1 + k √c
Expanding the LHS using the FOIL method =>
(3 + √c) (2√c -3)
= (3)(2√c) + 3(-3) + (√c)(2√c) -√c(3)
= 6√c -9 + 2(√c)² -3√c
= 3√c + 2c - 9 [(√c)² = c]
Setting this equal to the RHS of 1 + k√c gives us
3√c + 2c - 9 = 1 + k √c
Since c and k are prime numbers, √c is irrational.
Therefore we match the irrational terms to get
3√c = k√c
=> k = 3 [divide both sides by √c]
Substitute k = 3 into 3√c + 2c - 9 = 1 + k √c
=> 3√c + 2c - 9 = 1 + 3√c
Add 9 to both sides
=> 3√c + 2c - 9 + 9 = 1 + 9 + 3√c
=> 3√c + 2c - 0 = 10 + 3√c
Subtract 3√c from both sides to eliminate this term on both sides
=> 3√c - 3√c + 2c - 0 = 10 + 3√c 3√c
=> 0 + 2c = 10 + 0
=> 2c = 10
Dividing by 2 on both sides gives us
c = 5
Answer: c = 5, k = 3
A skateboard in a
store in Charlottetown, PEI, costs
$39.99. It is on sale for 30% off.
The taxes are 16%. What is the sale
price of the skateboard including taxes?
A student says, “$39.99 – 30% discount
+ 16% taxes is the same as calculating
$39.99 – 14%.”
Is the student’s reasoning correct?
Answer:
No, the reasoning is not correct.
Step-by-step explanation:
39.99 x .14 = 5.5986 Does it make sense that the sales price plus the tax would be $5.60? Doesn't that seem really low?
39.99 x .3 = 11.997 is the amount that we are taking off of the original price.
39.99 - 12 (Rounded to the nearest cent) is 27.99.
Now we pay the tax on the discounted amount of the item.
27.99 x .16 = 4.4784 or 4.48 rounded to the nearest cent.
The out the door cost of the item
is 27.99 + 4.48 = 32.48

What is the mathematical operation?An operation, often known as "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by number of operands.
Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are operations that are most frequently studied. A constant is operation with arity zero, often known as a nullary operation. An example of an operation of arity 3, sometimes known as ternary operation, is the mixed product.
The arity typically assumed to be limited. The "typical" operations of finite dimensionality are referred to finiteary operations when infinitary operations are taken into consideration.
Similar to an operation, but with partial function in place of a function, is the definition of a partial operation.

A quadrilateral is plotted on a coordinate plane. Each of the vertices of the quadrilateral undergoes the same transformation.Which transformation does not preserve the lengths of the sides of the quadrilateral?
Explanations :
(a) (x;y) →(x-3 ; -y+2 ) ; this preserves the lengths of the side, with a reflection across the x -axis .
(b) (x;y) →(2x +1 ; y-5 ); this does not preserve the length of sides, because the 2 multiply by x will change the length by factor of 2 .
(c) (x;y) → (-x+6 ;-y -8 ), preserves the lengths of sides, with reflection of y = -x .
(d) (x;y) →(-x -5 ; y+10 ) preserves the lenghts of the sides , with a reflection in the y -axis .
Two hikers are 33 miles apart and walking toward each other. They meet in 5 hours. Find the rate of each hiker if one hiker walks 2.2 mph faster than the other.
The rate of the slow hike is 2.2 mph and the rate of the faster hiker is 4.4 mph.
Here in this issue, we are managing linear equations which is a condition of one variable regularly composed within the form ax+b=0 , where a and b are real numbers and x is an unknown variable. Solutions to linear equations allude to a linear equation that can have zero, one, or infinitely various solutions. A linear equation with no solutions simplifies to an untrue statement such as 1=0. A linear equation with one solution rearranges to a solution of the form x=n where n may be a real number. A Linear equation with infinitely various solutions simplifies to a true statement without a variable such as 1=1.
Here we considering the rate of the slow hiker to be x, so the rate for the fast hiker will be x+2.2
Since we know that distance = speed * time
therefore, the Distance covered in 5 hours by a slow hiker is 5x , wheras for fast hiker it will be 5(x+2.2)=5x+11 km
As we are given the condition that it i they are 33 miles apart, So
=>5x + 5x+11 = 33
=>10x = 33-11
=>10x = 22
x =22/10 => 2.2
So the rate of a slow hiker is 2.2 mph and the rate of a fast hiker is x+4.4= 4.4 mph.

Every radical can be rewritten has an exponent .
Extraneous Solutions occur because squaring both sides of a square root equation results in 2 solutions (the positive and negative number).
1. Exponents that are written as fractions are referred to as rational exponents.
The top of the rational exponent is the new exponent on the radical, and the bottom of the rational exponent is the root, therefore a rational power can be reinterpreted as a radical in this fashion.
2. Separate the radical expression from the equal sign on one side. Put every every clause over there on the other side. Square both sides of the equation if the radical is a square root. Raise both sides of the equation to the third power if it is a cube root. Write an expression as a radical if the expression has a logical exponent. By examining the exponent's numerator, you may determine the power. By examining the exponent's denominator, you can get the root. Raise the radicand to the power while using the base as the radicand, and use the root as the index.
3. Extraneous Solutions appear because there are two solutions when you square the two sides of a square root equation (the positive and negative number). As a result, one of those figures will represent an extra solution, or a solution that is added but does not satisfy the initial equation.

if the semi annual compound interest on rupees 8000 for 3/2 years is rupees 2648, what is the simple interest of the sum at the same rate and time?
The simple interest of the sum at the same rate and time is 2400
What is compound interest ?The interest that is paid on the principal and interest at regular intervals is known as compound interest.The difference between compound interest and simple interest starts to show after the first year, though.Beginning with the second year, interest is computed on both the principal amount and the interest from the prior year. As a result, interest on interest is another name for it.
Given that : Sum =8000 and time = [tex]\frac{3}{2} years[/tex] and rate is 20 %
When rate is calculate half yearly
R becomes [tex]\frac{R}{2}[/tex]
T becomes 2T
A = [tex]P(1+\frac{R}{100} )^{T}[/tex]
C.I = A-P
R = [tex]\frac{20}{2} = 10%[/tex]%
T = 2× [tex]\frac{3}{2} years[/tex] = 3years
A = [tex]P(1+\frac{R}{100} )^{T}[/tex]
A = 8000[tex]\frac{11}{10} ^{3}[/tex]
A = 8 ×1331
A = 10648
Now ,
C.I = A - P
C.I =10648 - 8000
C.I = 2468
The compound interest is 2468
Simple interest
A = P(1+rt)
A = 8000(1+0.2×1.5)
A =10400
S.I =A- P
= 10400 - 8000
=2400
