Answer:
Base area is 36 square meters
Step-by-step explanation:
The volume of a rectangular prism is V = (height)(length)(width). We know all of these dimensions except for the area of the base, which is (length)(width).
Solving this equation for (length)(width), we get:
volume 72 m^3
(length)(width) = (area of base) = -------------- = ------------- = 36 m^2
height 2 m

5 less than a number is equivalent to 1 more than three times the number.
The value of the unknown number is calculated as - 3
Let the unknown number = y
5 less than the number is written as = y - 5
1 more than three times the number is written as = 1 + 3y
Since the first statement and the second statement are equal, we can equate the two and solve for y.
y - 5 = 1 + 3y
collect similar terms together
y - 3y = 1 + 5
-2y = 6
y = -6/2
y = -3
Therefore, the number is - 3

What is an equivalent expression in the lowest terms?
a.convert 150 grades into degree
b.find x and y if : (x+3,4) = (6,y)
c.one angle of a right angled triangle is 60 grades. Find the other angles in degree
Answer:
Hope it helps
Step-by-step explanation:
a)= 1 grade = 9/10 degree
150 = 9/10 × 150 degree
= 135 degree
b ) = solution
x+3 = 6
so, x = 3
y = 4
c) = let the unknown angle be x
now,
converting 60 grades into degree
= 60×9/10
= 54°
now
54° + 90° + x = 180°
144°-180° = -x
so, x = 36°

Reorder the terms:
[tex]-9 + 2x = 5 + x[/tex]
Solving
[tex]-9 + 2x = 5 + x[/tex]
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
[tex]-9 + 2x + -1x = 5 + x + -1x[/tex]
Combine like terms: [tex]2x + -1x = 1x[/tex]
[tex]-9 + 1x = 5 + x + -1x[/tex]
Combine like terms: [tex]x + -1x = 0[/tex]
[tex]-9 + 1x = 5 + 0\\-9 + 1x = 5[/tex]
Add '9' to each side of the equation.
[tex]-9 + 9 + 1x = 5 + 9[/tex]
Combine like terms: [tex]-9 + 9 = 0[/tex]
[tex]0 + 1x = 5 + 9\\1x = 5 + 9[/tex]

At Horatio's machining company, it takes 2 minutes to manufacture each part and 10 minutes to pack all the parts for an order. Write an expression that shows how many minutes it will take to complete an order, assuming there are x parts in an order.
Answer:
f(x) = 2x + 10
Step-by-step explanation:
Let's call this function f(x), where f(x) is time to get the order ready and x is the number of parts:
f(x) = 2x + 10 Is the expression of this function.2x is the time to manufacture all parts of the order and 10 min is the time to pack them.
Answer:
2x + 10 is the correct answer :)

The value of x from the trigonometric relation is x = 210°
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin (-θ) = -sin (θ)
csc (-θ) = -csc (θ)
cos (-θ) = cos (θ)
sec (-θ) = sec (θ)
tan (-θ) = -tan (θ)
cot (-θ) = -cot (θ)
In the first quadrant, sin, cos and tan are all positive.
In the second quadrant going anti-clockwise, only sin is positive.
In the third quadrant going anti-clockwise, only tan is positive.
In the fourth quadrant going anti-clockwise, only cos is positive
Given data ,
Let the trigonometric relation be represented as A
Now , the value of A is
sin ( 90° - x ) = -( √3/2 ) be equation (1)
On simplifying the equation , we get
sin 60° = √3/2
Substituting the values in the equation , we get
sin ( 90° - x ) = - sin ( 60° )
And , sin (-θ) = -sin (θ)
Substituting the values in the equation , we get
sin ( 90° - x ) = sin ( - 60° )
On further simplification , we get
( 90° - x ) = ( - 60° )
Adding x on both sides of the equation , we get
x - 60° = 90°
Adding 60° on both sides of the equation , we get
x = 150°
x = π/3 + 90 + 2πn
x = 2π/3 + 90 + 2πn
Therefore , the value of x is 150° or 210°
Hence , the value of x is 210°

Answer:
(4x10^1)(2x10^4)
=40^1 × 20^4
=800^5
Answer:
8 x 10^5
Step-by-step explanation:
We can start by grouping the powers of ten together and the other numbers together, as you can move numbers around when multiplying:
4 x 2 x 10^1 x 10^4
4 multiplied by 2 is 8, so we can put that in:
8 x 10^1 x 10^4
Next, using the product rule, 10^1 x 10^4 would be ten to the power of the sum of the two exponents, or 10^(4 + 1), which is 10^5.
We will be left with
8 x 10^5
This is in scientific notation, so no further modification is needed.
Is 512 is not a perfect square
Answer:
A perfect square is a number that can be expressed as the product of two equal integers.
The only way to accurately calculate if a number is a perfect square is to find the factors. Before we go through the trouble of finding the factors, there is a quick trick you can use to help determine if you need even need to do the extra work.
Try these steps first:
A number that is a perfect square never ends in 2, 3, 7 or 8. If your number ends in any of those numbers, you can stop here because your number is not a perfect square.
Obtain the digital root of the number. The digital root essentially is the sum of all of the digits. If you're lost, don't worry, we'll go over each step in more detail below.
All possible numbers that are a perfect square have a digital root of 1, 4, 7, 9.
Let's try it...
Step 1:
What is the last number of 512? It is this number: 512. The answer is 2. Is 2 in the list of numbers that are never perfect squares (2, 3, 7 or 8)?
Answer: YES, 2 is in the list of numbers that are never perfect squares. The number 512 is NOT a perfect square and we can stop here as there is not need to complete the rest of the steps.

Need help plz on delta math
Answer: The x intercept for Line A is 2 and the x-intercept for line B is -6.
Step-by-step explanation:
Line A uses the equation y = -1/2x + 1 and to find the x intercept y has to be zero so set the equation equal 0 and solve for x.
0 = -1/2x + 1 Subtract one from both sides
- 1 -1
-1 = -1/2x divide both sides by -1/2
x = 2
So the x intercept for A is 2
For Line B it already indicates the x intercept because that is when y is 0. So when y is 0 then x is -6.

list 2 differences between y = sin x and y = cos x
Answer:
- sin(x) is the ratio of the opposite leg to the hypotenuse in a right triangle, while cos(x) is the ratio of the adjacent leg to the hypotenuse in a right triangle.
-The graph of y = sin(x) at x = 0 starts at the origin, and then increases, while the graph of y = cos(x) starts at a max, and then decreases.
Here's a 3rd: sin(x) is the cofunction of cos(x), which means that sin(x) = cos(90-x). This also shows that they are different.
