What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that Laura has bought a skirt and a blouse for 66 euros, both had the same price but they have given her a 20% discount on the skirt and only 15% on the blouse.
The cost skirt would be -
${x} = 66 - {20% of 66}
${x} = 66 - {20/100 x 66}
${x} = 66 - {66/5}
${x} = 66 - 13.2
${x} = 52.8
The cost of blouse would be -
${y} = 66 - {15% of 66}
${y} = 66 - {15/100 x 66}
${y} = 66 - {3/20 x 66}
${y} = 66 - 9.9
${y} = 56.1
Therefore, the cost of the skirt and blouse after the discount would be -
$52.8 and $56.1 respectively.

a sandwich shop purchases a used pizza oven for $955. after 5 years, the oven will have to be discarded and replaced. write a linear equation giving the value v of the equipment during the 5 years it will be in use. (use t to represent the year.)
A linear equation giving the value v of the equipment during the 5 years it will be in use is v = 955 - 191t
A linear equation models a linear relationship between two variables, where the rate of change between the two variables is constant. In this case, we can model the value of the equipment as it depreciates over time using a linear equation.
Since the value of the equipment decreases linearly over time, we can write an equation in the form:
v = a - bt
where v is the value of the equipment in year t, a is the initial value of the equipment, and b is the constant rate of depreciation.
Since the initial value of the equipment is $955, we can set a equal to 955. To find the constant rate of depreciation, we need to find the change in value over the 5 years it will be in use and divide by the number of years. Assuming after 5 years the value is 0,
constant rate of depreciation = 955/ 5
= 191
So, with a = 955 and b = $191 per year, the linear equation that models the value of the equipment over time is:
v = 955 - 191t
This equation gives the value of the equipment in year t based on the initial value and the constant rate of depreciation.

jokes are listed in a magazine, where one is written by a female author. If the order in which these jokes are told makes a difference in terms of how they are received, how many ways can they be delivered if a joke by a man is told first?
Answer: Let's assume that there are "m" jokes written by male authors and "f" jokes written by female authors, such that m + f = total number of jokes in the magazine.
If a joke by a man is told first, there are (m - 1)! ways to arrange the remaining m - 1 jokes written by male authors and f! ways to arrange the jokes written by the female author. The total number of ways the jokes can be delivered is (m - 1)! * f!.
So, the answer is (m - 1)! * f! ways to deliver the jokes if a joke by a man is told first.

A rocket is launched in the air. Its height in feet is given by h(t)= -16t^2+88t where t represents the time in seconds after launch. How long is the rocket in the air?
Answer: ___ seconds
A rocket is launched with height function h(t)= -16t²+88t for time 't' in seconds the rocket is in the air for the time t = 5.5 seconds.
A rocket launched with height function :
h(t)= -16t²+88t
't' represents the time in seconds
'h' is the height of rocket.
Time for which rocket is in the air given by :
When h(t) = 0
Substitute the value we get,
⇒ -16t²+88t = 0
⇒ -16t ( t - 5.5 ) = 0
⇒ -16 ≠ 0 or t ≠ 0 or ( t - 5.5 ) = 0
Time can never be zero.
hence,
( t - 5.5 ) = 0
⇒ t = 5.5 seconds
Therefore, the time of the rocket when it is in the air is equal to 5.5 seconds.

A cedar canoe has a mass of 40 kilograms and a density of 400 kilograms per cubic meter. Calculate its volume.
The volume of the cedar canoe with a mass of 40 kilograms and a density of 400 kilograms per cubic meter is 0.1 cubic meters.
What is the volume of the cedar canoe?Density is expressed mathematically as;
p = m / v
Where m is mass and v is volume.
Given that;
Mass of the canoe m = 40kgDensity p = 400 kg/m³Volume v = ?To determine the volume, plug the given values into the above formula and solve for v.
p = m / v
v = m / p
v = 40kg / 400 kg/m³
v = 40kgm³ / 400 kg
v = 40m³ / 400
v = 0.1 m³

solid shapes are regular when all the faces are eaqual which 3d shapes is regular?
a) cylinder
b) cube
c) cuboid
A regular solid shape is defined as a three-dimensional object that has all its faces congruent and all its vertices congruent. In other words, all faces have the same shape and size and all vertices have the same angle measures.
Among the options provided, only the cube is a regular solid shape. A cube is a three-dimensional object that has six equal square faces. Each face is a square and each vertex has the same angle measure. The edges of a cube are congruent and the shape is highly symmetrical.
The cylinder is not a regular solid shape because it has two congruent circular faces and one curved surface, which is not congruent to the other two faces. The vertices of a cylinder also have different angle measures.
The cuboid is not a regular solid shape because it has six rectangular faces, and the shape is not highly symmetrical. The vertices of a cuboid also have different angle measures.
In conclusion, a regular solid shape must have congruent faces and congruent vertices, and only a cube satisfies these conditions. It is important to note that not all regular shapes are regular solid shapes, for example, a sphere is a regular shape, but it is not a regular solid shape because it has no faces, vertices or edges.

what is the probability of having no defectives in a sample of size 3 from a lot of 24 items with 5 known defectives.
The probability of having no defectives in a sample of size 3 from a lot of 24 items with 5 known defectives is 0.0403 or approximately 4%.
The probability of having no defectives in a sample of size 3 from a lot of 24 items with 5 known defectives can be calculated using the binomial probability formula. The formula is given by:
P(X=k) = (n choose k) * p^k * (1-p) ^(n-k)
where:
n = sample size (3)
k = number of successful trials (0)
p = probability of success (probability of an item being non-defective)
Since there are 24 items in the lot and 5 of them are known to be defective, the probability of success (p) is equal to 19/24.
Plugging in the values, we get:
P(X=0) = (3 choose 0) * (19/24) ^0 * (5/24) ^3
= 1 * 1 * (5/24) ^3
= (5/24) ^3

Answer:

Step-by-step explanation:
Rounding to 2 decimal places means keeping only 2 digits after the decimal point and adjusting the third digit, based on the rules of rounding. In this case, the number 0.4277 would be rounded to 0.43. This is because the third digit after the decimal point (7) is 5 or greater, so we round up the second digit (2) to 3. This gives us the rounded number 0.43, which has only 2 decimal places.
