dimensions definition
Final answer:
Dimensions in physics are the measurable extents that define an object or quantity, such as length for one-dimensional measures and volume for three-dimensional space. Length is typically measured in meters, while volume is a product of lengths and measured in cubic meters. Dimensional analysis is used for unit conversion and to ensure equations are dimensionally consistent.
Explanation:
The term dimensions in the context of physics refers to the measurable extents of any object or physical quantity, which are necessary for defining that quantity. Length is a one-dimensional measure, representing the extent of an object along its greatest dimension, typically measured in meters or its derived units such as kilometers (km) or micrometers (μm). On the other hand, volume is a three-dimensional measure of the space occupied by a sample of matter, represented as the product of lengths in each dimension and has the dimension L3. Dimensional analysis is a method in physics for converting between units using conversion factors to ensure that equations and calculations are dimensionally consistent. Physical quantities must align in dimension in any mathematically correct equation, otherwise known as having dimensional consistency, meaning each term within an equation must have the same dimensional expression.

There are 26.2 miles in a marathon. Enter the number of miles using a mixed number in simplest form.
Answer:
[tex]26\frac{1}{5}[/tex] miles.
Step-by-step explanation:
We have been given that there are 26.2 miles in a marathon. We are asked to find the number of miles using a mixed number in simplest form.
First of all, we will convert our given number as a fraction by multiplying and dividing by 10 as:
[tex]26.2\times\frac{10}{10}=\frac{262}{10}[/tex]
[tex]\frac{262}{10}=26\frac{2}{10}[/tex]
[tex]26\frac{2*1}{2*5}[/tex]
[tex]26\frac{1}{5}[/tex]
Therefore, the number of miles in mixed number would be [tex]26\frac{1}{5}[/tex] miles.
On the track team, 3/5 of the members are boys. Of these boys, 4/7 are sixth graders. Of the sixth-grade boys on the team, 1/3 are runners. What fraction of the track team are sixth-grade boy runners?
By multiplying the fractions 3/5, 4/7, and 1/3, which represent the boys, sixth graders, and runners respectively, we find that 4/35 of the track team are sixth-grade boy runners.
To find the fraction of the track team that consists of sixth-grade boy runners, we'll need to multiply three fractions that represent different parts of the team:
The fraction of the team that are boys: 3/5
The fraction of these boys that are sixth graders: 4/7
The fraction of the sixth-grade boys that are runners: 1/3
Now, multiplying these numbers expressing common fractions gives us:
(3/5) × (4/7) × (1/3) = 12/105 = 4/35.
So, 4/35 of the track team are sixth-grade boy runners.

Karita had 138.72 in her checking account. She wrote checks for 45.23 and 18.00. Then she made a deposit of 75.85 into her account. What's the best estimate for how much money is in karitas account now?
Answer:
The best estimates is $150
Step-by-step explanation:
The initial value in her account was 138.72
She wrote checks, so this are debits. So, you have to substract the values of the checks from the initial number.
[tex]138.72-45.23-18=75.49[/tex]
Then she made a deposit of 75.85, a deposit is credit value, so you have to add this number to the account value.
[tex]75.49+75.85=151.34[/tex]
Estimated ammount of money on karitas account is $150.

is 3x-5+y=2y-4 linear if so write the equation in standard form and give the values of A B and C
Final answer:
The given equation is linear and can be written in standard form as 3x - y = 1, where the coefficients are A = 3, B = -1, and C = 1.
Explanation:
The equation 3x - 5 + y = 2y - 4 is indeed linear. To write it in standard form, we combine like terms and move all terms involving variables to one side of the equation and the constant terms to the other side. Subtracting y from both sides and adding 5 we get 3x - y = 1. Here, A is 3, B is -1, and C is 1.
A pitcher contains 2/3 quart of water. If an equal amount of water is poured into 6 glasses how much water will each glass contain?
Answer:
1/ 9 quart of water or 0.11 quart
Step-by-step explanation:
A pitcher contains= [tex]\frac{2}{3}[/tex] quarts of water
An equal amount of water is to be poured into 6 glasses
We have to find the amount of water in each glass
Hence, amount of water in each glass = [tex]\frac{amount of water }{number of glasses}[/tex]
Hence, amount of water in each glass = [tex]\frac{[tex]\frac{2}{3}[/tex] }{6}[/tex]
Amount of water in each glass = [tex]\frac{2 }{18}[/tex]
Amount of water in each glass = [tex]\frac{1 }{9}[/tex]
Hence, amount of water in each glass = 0.111 quart
Write an expression that represents the sum of b and 5 times 2
The mathematical expression for the sum of b and 5 times 2 is b + (5 × 2).
The expression that represents the sum of b and 5 times 2 is written as b + (5 × 2). The parentheses indicate that the multiplication should be done first, resulting in 5 times 2, which equals 10. Then, you add the value of b to this result. Therefore, the complete expression evaluates to b + 10.
It is important to understand the role of parentheses in mathematical expressions. Parentheses define the order of operations, ensuring that operations inside them are carried out first. Without the proper use of parentheses, expressions can yield different results.
