Find the volume of a pyramid with a square base, where the perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm. Round your answer to the nearest tenth of a cubic centimeter.
Answer:
V=2.8cm^3
Step-by-step explanation:
The volume of a pyramid with a square base should be considered as the 2.8 cubic centimeter.
Calculation of the pyramid:Since
perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm.
So, here
we know that
volume of a pyramid = [tex]1/3(length * width * height)[/tex]
And,
perimeter of a square = [tex]4 * length[/tex]
6.9 = 4 x length
So,
length = 1.725
Now the volume is
[tex]= 1/3 * (1.725 * 1.725 * 2.8)[/tex]
= 2.8

Stefan sells Jin a bicycle for $125 and a helmet for $18. The total cost for Jin is 130% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
PLEASE TELL ME AN ANSWER, THIS TEST IS DUE IN 5 MINUTES.
Answer: The selling cost for Stefan bicycle = $114 and
the selling cost of a helmet = $18.
The total cost for Jin is 120% of the money spent.
Let us assume purchasing cost of a bicycle = $x.
Purchasing cost of a halmet = $y.
For bicycle
120% of x is $114
=> 1.20 × x = 114
Dividing both sides by 1.20, we get
x=$95.
For helmet.
120% of y is $18.
=> 1.20 × y = 18.
Dividing both sides by 1.20, we get
y = $15.
Therefore, Stefan spent originally to buy a bike $95 and $15 to buy a helmet.
$114 - 95 = $19
$18 - 15 = $3.
Therefore, he made $19 by selling the bicycle and $3 by selling the helmet to Jin.

Answer:
The y-intercept is 2 and the slope is 1/2. So the equation is y = 1/2x + 2
Step-by-step explanation:
The y-intercept is where the line starts on the y-axis. For the slope to the next point on the line you have to move 2 units to the right and 1 unit up. When writing the slope as a fraction, you always put how far you move up or down above how far you move to the right or left.

Find the equation of the line that passes through the points (1, 6) and (2, 8).
By substitution in this equation, show that (3, 10) also lies on this line.
Answer:
y = 2x + 4
Step-by-step explanation:
y2 - y1/ x2- x1
= 8 - 6 / 2 - 1
= 2
So now our equation is y = 2x + b (from y = mx+b). Now plug in the coordinates to find the y-intercept.
y = 2x + b
8 = 2(2) + b
8 = 4 + b
4 = b
The y-intercept is 4.
If we put one of the values like the x in the equation, we should get the y value.
y = 2x + 4
y = 2 (3) + 4
y = 6 + 4
y = 10

tell me if the statement below is sometimes, always, or never true. justify your reasoning, (the Expressions x - 3 + y -3 represent the same value.)
Answer:
Sometimes true. It may be true at times if x or y equal each other, but if they do not equal each other it is not true
Step-by-step explanation:
We are given two expressions: x -3 and y - 3
Here x and y are two different variables.
These expressions are equal, when the value of x and the value of y are equal.
x - 3 = y -3 if x = y.
Therefore, the two expressions have the same value in sometimes.
That is, when x = y, then the value of two expressions are the same.
Example.
If x = 2 and y = 2, then
x - 3 = y - 3
2 - 3 = 2 - 3
-1 = -1
If they have different values, for x = 2 and y = 3
x - 3 = y - 3
2 - 3 = 3 -3
-1 = 0
Which is not true.
Therefore, the answer is sometimes.
The measures of the angles of Triangular garden are in the ratio 2:5:5. What are the measures of the angles? Classify the triangle based on its sides
Answer:
We know that the sum of all the interior angles of a triangle is always equal to 180°.
And we know that the angles are in a ratio of:
2:5:5
So if we have an angle (unknown) θ, the angles of this triangle will be written as:
2*θ
5*θ
5*θ
Now remember that the sum of the 3 angles is equal to 180°, this leads to:
2*θ + 5*θ + 5*θ = 180°
Now we can solve this for θ
(2 + 5 + 5)*θ = 180°
12*θ = 180°
θ = 180°/12 = 15°
This means that the angles of this triangle are:
2*θ = 2*15° = 30°
5*θ = 5*15° = 75°
5*θ = 5*15° = 75°
Now we want to classify this triangle based on this, we have two equal angles, which implies that we must have two equal sides and another different side.
Then this is an isosceles triangle.

The price of a book, which regularly sells for $24, was marked down by 25%. A coupon reduced the price by another 10%. What was the final selling price?
Answer:
$16.20
Step-by-step explanation:
24.00 × 25%= 6.00
24.00 - 6.00 = 18.00
18.00 × 10%=1.80
18.00 - 1.80 = 16.20
A percentage is a way to describe a part of a whole. The final cost of the book will be $16.2.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given the cost of the book is $24. Therefore, the cost of the book after a 25% discount is,
Cost of book after discount = $24×(100%-25%) = $18
Now, the cost after the 10% counpon will be,
Cost after the 10% counpon = $18×(100%-10%) = $16.2
Hence, the final cost of the book will be $16.2.

Given figures are neither congruent nor similar.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
We must compare the equivalent sides and angles of two figures in order to determine if they are congruent or comparable.
As congruent figures are the same in size and shape, their corresponding sides and angles are also identical in size. We simply need to identify one set of related sides or angles that are not equal to demonstrate that two figures are not congruent.
Comparable figures have the same form but different sizes, therefore their corresponding sides are proportionate even though their corresponding angles are equal in size. Finding one pair of matching angles that are not equal or a pair of corresponding sides that are not proportional will demonstrate that two figures are not similar.
