The bases of the prism below are right triangles. If the prism's height measures 8 units and its volume is 60 units³, solve for x.
Answer:
3
Step-by-step explanation:
Volume of prism = 0.5 times height times length times width
60 = (0.5)(8)(5)(x)
120 = 8(5)(x)
120 = 40x
x = 3
Let me know if its right
Length of another side of base x = 3 unit
What is prism?A prism has a solid shape consisting of two identical ends (such as triangle, square, rectangle, etc.), flat faces or surfaces and uniform cross-section across its length. The cross-section looks like a triangle hence called triangular prism. The shape of the prism does not have any curve. Therefore, a prism can have square, rectangular, pentagonal and other polygon shapes but not the circular shape.
Height of the prism = 8units
Length of one side of base = 5 units
Length of another side of Base = x
Base is a right angle
Base Area = 5x/2
Volume of prism = 60 unit³
Volume of Prism = Base Area × Height
60 = (5x/2) × 8
60/8 = 5x/2
x = 120/40
x = 3 unit.
Hence, x = 3 unit which is length of another side of base.

Question 15 of 26
AABC has side lengths that measure 10 centimeters, 10 centimeters, and 15
centimeters. Which of the following best describes this type of triangle?
Answer:
isosceles
Step-by-step explanation:
▪︎ Isosceles triangle is a triangle that has two sides of equal length.
the lenth of a rectangle is twice the width if the permeter is 20 cm find the width
L = 2W
perimeter = 2( L + W ) = 20 .
2 ( 2W + W ) = 20
6 W = 20
W = 20/6
= 10/3
L = 20/3
Answer:
10/3
Step-by-step explanation:
Given properties of the rectangle:
The length is twice the width ( So we can say l = 2w ) The perimeter is 20cmGiven this we want to find the width of the perimeter.
Creating a system of equation:
First off we know that perimeter = 2L + 2W
We also know that the perimeter of this rectangle is 20 cm
So we can say that 20 = 2L + 2W
We also know that the length of this rectangle is twice the width or in other words l = 2w
So we have the two equations, 20 = 2l + 2w and l = 2w
Solving the system:
We are going to use the substitution method to solve this system.
The substitution method works when you have two equations, one can be just a plain equation but the other must have one of the variables defined ( by itself on either side of the equal sign )
If you have one of the variables defined, you can plug it in ( substitute ) into the other equation and solve for the other variable.
Plugging in the defined variable into the other equation
Equation : 20 = 2l + 2w
Defined variable : l = 2w
==> plug in l = 2w
20 = 2(2w) + 2w ( now we solve )
==> multiply 2 and 2w
20 = 4w + 2w
==> combine like terms
20 = 6w
==> divide both sides by 6
20/6 = w
==> simplify fraction
10/3 = w
The width = 10/3
Checking our work:
First we must solve for length as well
Solving for length by plugging in width into either equation
l = 2w
==> plug in w = 10/3
l = 2(10/3)
==> multiply 2 and 10/3
l = 20/3
Now to check our we we plug in the length and width into both equations, if both are true then our answer is correct
Equation 1 : 2l + 2w = 20
==> plug in l = 20/3 and w = 10/3
2(20/3) + 2(10/3) = 20
==> simplify multiplication
40/3 + 20/3 = 20
==> add fractions
20 = 20
Equation 2 : l = 2w
==> plug in l = 20/3 and w = 10/3
20/3 = 2(10/3)
==> multiply 2 and 10/3
20/3 = 20/3
Both are correct so our final answer is correct as well! :)

Which line is parallel to line r?
Oline p
O line q
O line s
Oline t
Answer:
Line s
Step-by-step explanation:
They are the same distance apart, so this makes them parallel.
By the definition of parallel lines, the line r is parallel to line s.
What is Coordinate System?Arrangement of reference lines or curves used to identify the location of points in space is called as Coordinate System.
We have to find the line which is parallel to line r.
Parallel lines are the lines that do not intersect or meet each other at any point in a plane.
They are always parallel and are at equidistant from each other.
Parallel lines are non-intersecting lines.
We can also say Parallel lines meet at infinity.
As we observe the figure line s is parallel to line r and it is equidistant from r.
Hence, line s is parallel to line r.

Answer:
x = - 1
Step-by-step explanation:
3(x + 1) = - 2(x - 1) - 4 ← distribute parenthesis on both sides
3x + 3 = - 2x + 2 - 4
3x + 3 = - 2x - 2 ( add 2x to both sides )

5x = - 5 ( divide both sides by 5 )

Answer:
[tex]5^{10} \cdot 5^{-7} = 5^3[/tex]
[tex]\frac{5^{10}}{5^{-7}} = 5^{17}[/tex]
Step-by-step explanation:
You have two equations:
[tex]5^a \cdot 5^b = 5^3[/tex]
[tex]\frac{5^a}{5^b} = 5^{17}[/tex]
But since
[tex]x^a \cdot x^b = x^{a+b}[/tex]
you only need to solve a+b = 3 and a-b=17
Rewrite the second as a = 17+b and plug it into the first:
17+b + b = 3, then you find, 2b = -14, so b = -7.
Then a=3-b, so a = 10.
Part A: In your own words, describe the steps that are necessary to determine whether angles are coterminal.
Part B: Explain why coterminal angles have a difference that is a multiple of 360° degrees, such as 720° or 1080°.
Part C: Find three angles that are coterminal with an angle measuring 75°. Show all work.
Answer:
Part A:
In order to find a coterminal angle, or angles of the given angle, simply add or subtract 360 degrees of the terminal angle as many times as possible.
Part B:Simply put, coterminal angles start at 0° and end at the same place, though in different directions and multiple times around (you're probably going to want to make that sound a little more formal). Since each time around is 360°, boom
Part C: 75° is in Quadrant II, right? If I go one more time around, 75 + 360 = 435°. I can also go "backward. Starting at 0 and going clockwise, I'm going 75 fewer degrees than all the way around, so 360-75 = 285° but since I'm going "backward" 75 - 360 = -285°. One more is on you.
Step-by-step explanation:
a rectangle has an area of 7.5m2. one of the sides is 0.3m in length. what is the perimeter of the rectangle?
Step-by-step explanation:
the area of a rectangular is
length × width
we know the area and one side, let's say it's the width (it does not matter, as multiplication are commutative, and a×b = b×a).
so,
7.5 = length × 0.3
length = 7.5 / 0.3 = 25 m
the perimeter of a rectangle is
2×length + 2×width = 2×25 + 2×0.3 = 50 + 0.6 = 50.6 m

How to solve the difference?
Here we want to solve:
[tex](5*10^{-7}}) - (7*10^{-9})[/tex]
To solve this, we should have the same exponent in both sides, to get that, we can rewrite the first number as:
[tex]5*10^{-7} = 500*10^{-9}[/tex]
Replacing that, we will get:
[tex](500*10^{-9}) - (7*10^{-9}}) = 493*10^{-9}[/tex]
To write it in standard form, we need to move the decimal point 9 times to the left, so we get:
