Carol has 1\frac{5}{8} cups of yogurt to make smoothies. Each smoothie uses \frac{1}{3} cup of yogurt.
What is the maximum number of smoothies that Carol can make with yogurt?
Carol can make a maximum of 4 smoothies with the available yoghurt
Cups of yoghurt Carol has for making smoothies = 1 5/8 cups
Yoghurt Carol has in improper fractions = 13/8 cups
Cup of yoghurt used to make smoothie = 1/3 cups
Fractions: A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.
Number of smoothies Carol can make = Total available yoghurt with Carol/Yoghurt used to make a smoothie
= (13/8)/(1/3)
= 39/8
Converting the fraction into a mixed fraction we get: 4 7/8 smoothies
So, she can make 4 cups of smoothie

The integer is 5 and the next consecutive odd integer will be 7.
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
let the integer be x
then, next consecutive odd integer will be x + 2
Now, according to the question :

From the tape diagram, your allowance and your friends' allowance is $48 and $32 respectively.
What is tape diagram?
A tape diagram is a visual representation that looks like a piece of tape and is used to help with ratio calculations, addition, subtraction, and most frequently multiplication. A divided bar model, fraction strip, length model, or strip diagram are other names for it. It is employed in mathematics education to help elementary school-aged children solve word problems. Students can use a tape diagram as a pictorial model to represent a mathematical relationship or to better understand a mathematical concept. Although they are frequently used with word problems, tape diagrams are helpful for solving many different kinds of math problems.
Let the ratio is given by 3:2 and total is 5
hence, 5 parts represent $80, so each part represents= 80/5= 16

recall that the perimeter of a square is 4 times as large as the length of one of the sides of the square. let x represent the length of one side of a square (in inches), and let y represent the perimeter of that square (in inches). y is a function of x , so we can define a function f to represent this relationship (e.g., f ( x )
The function which represents the relation between the perimeter and the length of the square is; y = 4x.
What is described as the function?A function is described as the connection between a collection of inputs that each have one output. A function is a relationship between inputs in which each input is connected to exactly one output. Every function does have a domain and a codomain, as well as a range. In general, a function is denoted by f(x), in which x is the input. A function's general representation is y = f. (x).For the given question;
Let x be the side of the square.
Let y be the perimeter of the square.
Perimeter is 4 times the side of the square.
Then,
Perimeter = 4×side
y = 4x.
Thus, the function which describes the relation between the perimeter and the side of square is y = 4x.

When an integer is subtracted from 3 times the next consecutive integer, the difference is 23. Find the value of the lesser integer.
Answer:
10
Step-by-step explanation:
To find the value of the smaller integer, start by letting a variable be that integer. This helps us to refer to the integer with greater ease in our working.
Let the smaller integer be x.
Consecutive numbers refers to numbers coming after one another, such as 1, 2 and 3.
The next integer coming after the integer x would thus be (x +1). Three times the next consecutive integer would then be 3(x +1).
Subtract refers to a minus sign, thus the equation would be:
3(x +1) -x= 23
Expand:
3x +3 -x= 23
Simplify:
2x= 23 -3
2x= 20
Divide both sides by 2:
x= 20 ÷2
x= 10
Thus, the smaller integer is 10.

TheThe number of miles that a signal sent from Station 1 to the satellite and then to Station 2 will have to travel is; 48,135 miles.
Number of milesDistance from Station 1 to satellite:
tan8.7 = length of longest leg / length of longest leg
tan8.7 = 3963/length of shortest leg
Length of longest leg=3963/tan8.7°
Length of longest leg=3963/0.15302150298
Length of longest leg =25,898 miles
Distance from Station 2 to satellite:
sin 8.7 = length of longest leg / length of hypotenuse
sin 8.7 = 3963/length of hypotenuse
Length of hypotenuse =3963/ sin 8.7
Length of hypotenuse =3963/0.1526082024
Length of hypotenuse=26, 200 miles

What are relations in Math?In mathematics, a relation is a group of ordered pairs that expresses the relationship between two sets. In arithmetic, a relation is called a function if it connects each element of the domain to a single element of the codomain. A relation could be a function or it could not. Relations are all functions.Eg :- The Association between Height and Age
This is a relation since you would get various heights if you entered a specific age and checked all the persons of that age. Nevertheless, if you were to look at a person's height over time, it would depend on their age.

Under certain conditions the pressure of a gas varies directly with the temperature. When the - pressure is 800 psi, the temperature is 400°. What is the temperature when the pressure is 450
The temperature when the pressure is 450 is 225°.
What is Direct Variation?In the case of an increase or decrease in both quantities by the same factor, two quantities are said to follow a direct variation. As a result, when one quantity rises, the other follows suit, and vice versa when one quantity falls. In other words, if the ratio of the first quantity to the second quantity is a constant term, the quantities are said to be directly proportional to one another. The term "coefficient or constant of proportionality" refers to this constant number.Given:
The pressure of a gas varies directly with the temperature.
So, P ∝ T
P = kT , here k is the constant of proportionality
Pressure(P) = 800psi
Temperature(T) = 400°
Putting the values to get the value of k,
P = kT
800 = 400k
k = 2
We need to find the temperature when the pressure is 450.
P = kT
450 = 2T
T = 450/2
T = 225°
Therefore, the required temperature is 225°.

A circular pond has a diameter of 15 feet which expression can be used to find the circumference in feet 
The expression used for finding the circumference of the circular pond is; C = 2π(d/2) feet.
What is defined as the circumference?The circumference of the circle, also known as the perimeter of the circle, is the measurement of the circle's boundary. The area of a circle, on the other hand, defines the region it occupies. If we expand a circle and draw a straight line through it, the length of the line is the circumference. It is typically measured in units such as centimeters or meters.For the given question;
Let 'd' be the diameter of the circular pond.
The diameter of the pond = 15 feet.
Let 'C' be the circumference of the circle;
The, the formula for finding the circumference of the circle is;
C = 2π(d/2) feet
For, d = 15 feet
C = 2π(15/2) feet
Take π = 3.14
C = 2×3.14×(15/2) feet
C = 47.1 feet

What is the domain of g?
If the domain of f is ( -1, 1), then the function g defined by g(x) = f((x + 1)/(x - 1)) has a domain of; (-2, 0)
What is the domain of the function?The domain of a function refers to the set of all possible intput values that make the function possible.
Now, we are given the function;
g(x) = f((x + 1)/(x - 1))
The domain would be a set of real numbers excluding 1 because at x = 1, the function is undefined.
Since the domain of f(x) is -1 < x < 1 ,
Then the domain of f(x + 1) is -1 < x + 1 < 1 .
domain of -1 < x + 1 < 1 will simplify to -2 < x < 0
Thus, we can say that the domain of f(x + 1) is (-2, 0).
