Answer:
79=23+8h
or,79-23=8h
or,56/8=h
or,7=h
therefore the value of h is 7.
Step-by-step explanation:
Hope it helps you!!
first you have to do the 23+ you have to make 23 into a subtraction problem in these expressions. 79-23= 56
Now you have to cancel out the 8in 8h and do the opposite of multiplication and do division on both sides 8h/8 cancels out and 56 divided by 8 = 7
your answer is 7 hope this helps

An exclamation is an emphatic expression of emotion or emphasis. It is often used to express strong feelings such as surprise, joy, excitement, anger, or disbelief. Exclamations are also used to emphasize a point or give an opinion. Exclamations are most commonly used in spoken language, particularly in informal conversations. They can also be used in written language, but they should be used sparingly. Exclamations are often followed by an exclamation point, although they can also be followed by a question mark or an ellipsis. Exclamations can be used to add emphasis or emotion to a statement, making it more powerful and memorable.

(Constant of Proportionality, Graphing Proportional Relationships, Real-World Proportional Problems HC) An ice cream shop serves chocolate milkshakes that are made with ice cream and milk. There is a proportional relationship between the number of scoops of ice cream and the amount of milk needed to make them. For every 1 scoop of ice cream, cup of milk is needed, and for every 5 scoops of ice cream, cups of milk are needed. Part A: Find the constant of proportionality. Show every step of your work. (4 points) Part B: Write an equation that represents the relationship. Show every step of your work. (2 points) Part C: Describe how you would graph the relationship. Use complete sentences. (4 points) Part D: How many cups of milk are needed for 18 scoops of ice cream? (2 points)
The constant of proportionality is 2
The equation of the relationship is s = 2mThe number of cups for 18 scoops is 9 cupsHow to determine the constant of proportionalityFrom the question, we have the following parameters that can be used in our computation:
1 scoop of ice cream = 1/2 cup of milk
5 scoops of ice cream = 2.5 cups of milk
The constant of proportionality (k) is then calculated as
k = Scoop of ice cream/Cup of milk
So, we have
k = 5/2.5
Evaluate
k = 2
The equation of the relationshipIn (a), we have:
k = 2
A proportional relationship is represented as
s = km
Where
s = scoop of ice cream
m = cup of milk
So, we have
s = 2m
How to graph the relationshipIn (b), we have
s = 2m
To graph the relationship, we start by generating a table of values and then plot the points
Number of cups for 18 scoopsRecall that
s = 2m
So, we have
18 = 2m
Divide by 2
m = 9
Hence, the number of cups is 9

The term graph in math is known as a pictorial representation or a diagram that represents data or values in an organized manner and the points on the graph often represent the relationship between two or more things.
Here we have given the expression y = -3.
Now, we have to plot these on the graph, then we get the graph like the following.
While looking into the given graph, we have identified that y = -3 is a horizontal line, and that passes through y-axis, here at a distance of 3 units on the bottom of the origin and is parallel to x-axis.
Therefore, the expression y = -3 makes the horizontal line which crosses the y -axis at (0,−3).

The area of the figure is 51.63 m²
How determine area of the composite figure?
A composite figure is figure that is made up of two or more different shapes.
The composite figure in the given image is made up of a rectangle, semicircle and a triangle. Therefore, the area of the composite figure will be the sum of the areas of the shape it is made of. Thus:
Area of figure = area if rectangle + area of semicircle + area of triangle
Area of figure = LW + 1/2πr² + 1/2bh
Area of figure = (6 × 5) + (1/2 × 3.14 × 3²) + (1/2 × 3 × 5)
Area of figure = 30 + 14.13 + 7.5

Draw a different quadrilateral. Can you guess the sum

The sum of the measures of the four interior angles of a quadrilateral is always 360°
What is a quadrilateral?A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.
Given is, A quadrilateral is a polygon with four sides. Consider the quadrilateral and the dashed segment
If we draw one diagonal to quadrilateral we will get two triangles i.e. △ABC and △ACD and we know that sum of the angles of a triangle is 180°
Sum of angles of quadrilateral ABCD = sum of angles of △ABC + sum of the angles △ACD
= 180° + 180°
= 360°
If we take examples of a square or a rectangle, we know that they are also a quadrilateral and also their each angle is right angle, i.e. 90°
Therefore, the sum of their interior angles will = 90×4 = 360°
Hence, we can say that the sum of the measures of the four interior angles of a quadrilateral is always 360°

The formula for the z-score is
z = (x - μ)/σ
x = standard value
μ = mean
σ = standard deviation
Given that the scored 75 points. The mean score of the student was 83.5 and the standard deviation was 6. 1.

What is random assignment?Random assignment improves the study's internal validity by ensuring that there are no systematic differences between the participants in each group. This allows you to conclude that the outcomes are due to the independent variable.In most cases, participants are randomly assigned to one of two groups: control or experimental. We can assume that the groups are essentially identical with the exception of the manipulation of the independent variable in the experimental group because participants are randomly assigned to either group.Random assignment is important in experimental research because it ensures that the experimental and control groups are comparable and that any differences between them are due to random chance.The complete question:
