The bases of the prism below are right triangles. The volume of the prism is 360
units. Find the height of the prism.
Answer:
15
Step-by-step explanation:
The surface of one of the triangles making the base of the prism is [tex]\frac 12 \cdot 6 \cdot 8 = 24[/tex].
At this point we can express the volume in terms of base surface and height as in [tex]360 = 24\cdot h[/tex] from which we can get the height by dividing by 24 both sides:
[tex]h= \frac{360}{24} = 15[/tex]

If a polygon has four right angles, then it is either a square or a rectangle.
Answer:
No because squares and rectangles are a type of polygon.
Step-by-step explanation:
A polygon is any shape with straight sides.
Polygon of having four right angles, then it is either a square or a rectangle.
What is polygon?A polygon is a closed object made of line segments rather than curves on a two-dimensional plane. Combining the terms poly, which means multiple, and gon, which means sides, creates the word polygon.
Given that,
A polygon has four right angles.
Since, A polygon of four right angles, then there will be four sides of polygon.
Four sides which are right angle can frame either a square or a rectangle.
A polygon is either a square or a rectangle.
This condition is true, because if all sides of polygon are equal then it will be a square and if all sides are not equal, then it will be a rectangle.
So, polygon with four right angles is either square or rectangle.

Can someone please help me figure out what’s 18 3/4 as a decimal
Solution:
We know that:
Given fraction: [tex]18\frac{3}{4}[/tex]Since the denominator is divisible by 100, we can solve this using an alternate way.
Step-1: Let's convert the mixed fraction into improper fraction.
Converting the mixed fraction to improper fraction:
[tex]18\frac{3}{4} \\\\= \frac{(18 \times4) + 3}{4} \\\\= \frac{72 + 3}{4} \\\\= \frac{75}{4}[/tex]
Step-2: Somehow, let's change the denominator to a 100.
Changing the denominator to a 100 using a proportion:
[tex]\frac{75x}{4x} = \frac{75x}{100} \\\\ 4x = 100 \\\\ x = 25 \\\\ \bold{Check:} \\\\\frac{75 \times25}{4 \times 25} = \frac{75 \times 25}{100} \\\\ \frac{1875}{100} = \frac{1875}{100} \bold{(True)}[/tex]
Step-3: Adjust the decimal to the right place.
Adjusting the decimal to the right place:
[tex]\frac{1875}{100} = 1875 \div 100 = 18.75[/tex]
Since 100 has 2 zeros, the decimal shifted 2 places to the left.
Thus, [tex]18\frac{3}{4}[/tex] in decimal form is [tex]18.75[/tex].
In decimal, mixed number [tex]18\dfrac{ 3}{4}[/tex] Can be written as 18.75.
To convert the mixed number [tex]18\dfrac{ 3}{4}[/tex] to a decimal, we can first convert the fraction part [tex]\dfrac {3}{4}[/tex] To its decimal equivalent, and then add it to the whole number part 18.
To convert 3/4 to a decimal:
Divide the numerator (3) by the denominator (4):
3 ÷ 4 = 0.75.
The fraction 3/4 is equivalent to 0.75 as a decimal.
Next, add the decimal equivalent of the fraction (0.75) to the whole number (18):
18 + 0.75 = 18.75.
Therefore, [tex]18\dfrac{ 3}{4}[/tex] As a decimal, is 18.75.

Solve the following system of Equations in any method you choose.
3x - y = 7
2x + y = 8
Answer:
x=3 and y=2
Step-by-step explanation:
Rewrite equations:
3x−y=7;2x+y=8
Step: Solve3x−y=7for y:
3x−y=7
3x−y+−3x=7+−3x(Add -3x to both sides)
−y=−3x+7
−y
−1
=
−3x+7
−1
(Divide both sides by -1)
y=3x−7
Step: Substitute 3x−7 for y in 2x+y=8:
2x+y=8
2x+3x−7=8
5x−7=8 (Simplify both sides of the equation)
5x−7+7=8+7 (Add 7 to both sides)
5x=15
5x5
=
15/5
(Divide both sides by 5)
x=3
Step: Substitute 3 for x in y=3x−7:
y=3x−7
y=(3)(3)−7
y=2(Simplify both sides of the equation)

A. Yes, because it has two straight lines.
B. Yes, because it passes the vertical line test.
O C. No, because it is not a curve.
D. No, because it fails the vertical line test.
Answer:
D. No, because it fails the vertical line test
Step-by-step explanation:
A function can only have 1 output for each input. If you are able to draw a vertical line and it touches the graph twice, then it has failed the vertical line test and is therefore not a function.

What are coordinates of points A, B, C, and D?
Answer:
See below.
Step-by-step explanation:
A = (-2/3, 0)
B = (-1/6, 0)
C = (1/2, 0)
D = (4/3, 0)
Step-by-step explanation:
the interval between 0 and 1 shows us, that on that scale the distance between 2 full numbers is split into 6 parts.
so, every little marker represents 1/6.
A goes 4 markers below 0 (left of 0) and is -4/6 = -2/3.
B goes 1 marker below 0 and is -1/6.
C goes 3 markers above 0 (right of 0) and is 3/6 = 1/2.
D goes 2 markers above 1 and is
1 + 2/6 = 6/6 + 2/6 = 8/6 = 4/3 = 1 1/3
please pick the format your teacher wants you to use to write the result.
if you actually need decimals instead of fractions :
-2/3 = -0.666666666...
-1/6 = -0.166666666...
1/2 = 0.5
4/3 = 1.333333333...

Alma borrows money from her mom to buy a $150 bike. She gives her mom $40 at the time of purchase and continues to pay her $10 each month until the bike is paid for in full. Alma wrote this equation to represent the amount y that she will have paid her mom after x months.Equation:y 5 40x 1 10Is her equation correct? How did she get that equation? If it is not correct, write a correct equation.
Given:
Total amount of bike = $150
Alma gives her mom $40 at the time of purchase and continues to pay her $10 each month until the bike is paid for in full.
Alma's equation: [tex]y=40x+10[/tex]
To find:
Whether her equation is correct or not.
Solution:
Let y be the amount that she will have paid her mom after x months.
She pays $10 each month.
She will $10x in x months.
Initially she gives $40 to her mom at the time of purchase. So, total amount she pays after x months is
Total amount [tex]=40+10x[/tex]
Since, y represents the amount that she will have paid her mom after x months, therefore
[tex]y=40+10x[/tex]
Alma multiply the variable x with 40 instead of 10.
Hence, Alma is incorrect and the correct equation is [tex]y=40+10x[/tex].
