Step-by-step explanation:
If 20 labourers=10 days
x labourers = 25 days
10x= 25×20
[tex] \frac{10x}{10} = \frac{25 \times 20}{10}[/tex]
Cancelling out by 10 on both sides
[tex]x = \frac{25 \times 2}{1} \\ x = 50 [/tex]
Therefore, it takes 50 labourers to complete the work at the same rate in 25 days.

Can you answer
-162= 8 - 5(4p + 2)
Answer: p = 8
Step-by-step explanation:
Given expression
-162 = 8 - 5 (4p + 2)
Expand parentheses and apply the distributive property
-162 = 8 - 20p - 10
Combine like terms
-162 = (8 - 10) - 20p
-162 = -2 - 20p
Add 2 on both sides
-162 + 2 = -2 - 20p + 2
-160 = -20p
Divide -20 on both sides
-160 / -20 = -20p / -20
[tex]\boxed{p=8}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
p= 8
Step-by-step explanation:
-162= 8 -5(4p +2)
Expand:
-162= 8 -5(4p) -5(2)
-162= 8 -20p -10
Simplify:
-162= -2 -20p
Bring p terms to one side, constants to the other:
20p= 162 -2
Simplify:
20p= 160
Divide both sides by 20:
p= 160 ÷20
p= 8

The triangle inequality Theorem states that the sum of the lengths of any two sides of the triangle is greater than the length of the third slide. The lengths of two sides of a triangle are 14ft and 27ft. Find the possible lengths of the third side
The third slide must have a length greater than __ft and less than _ft
Answer:
12 < x < 42 or x | ( 12,42 ) ft.
Step-by-step explanation:
15 + 27 = 42; 27 − 15 = 12 . Therefore the third side must be
less than 42 ft ant greater that 12 ft. Therefore possible length
of third side of size x is 12 < x < 42 or x | ( 12,42 ) ft [Ans]

Part C
How could you determine the coordinates of the vertices of a translated image without using a graph?
Using translation concepts, it is found that:
a) For a translation 6 units horizontally, 6 is either added or subtracted to the x-coordinate of the ordered pairs.
b) For a translation 3 units vertically, 3 is either added or subtracted to the y-coordinate of the ordered pairs.
c) The coordinates of the vertices of the translated image will be given according to the following rule: (x,y) -> (x ± 6, y ± 3).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For a translation 6 units horizontally, we have that:
If it is left, x -> x - 6.If it is right, x -> x + 6.Hence 6 is either added or subtracted to the x-coordinate of the ordered pairs.
For a translation 3 units vertically, we have that:
If it is down, y -> y - 3.If it is up, y -> y + 3.Hence 3 is either added or subtracted to the y-coordinate of the ordered pairs.
The coordinates of the vertices of the translated image will be given according to the following rule: (x,y) -> (x ± 6, y ± 3).

Select three involuntary muscles:
stomach
intestinal
heart
biceps
brain
I'll give Brainliest! :D
Answers:
A) stomachB) intestinalC) heart=============================================
Explanation:
The stomach muscle helps digest food. The muscle isn't something a person can control at will. Instead, the body handles it automatically. This is why choice A is one of the answers.
The intestinal muscles work in a similar fashion to help pass nutrients into the blood stream and also pass waste out of the body. All of these processes are done automatically and you don't have to think about them. They just happen. Therefore, choice B is another answer.
Another example of an automatic or involuntary muscle doing its own thing is the heart muscle. It continuously pumps blood to help distribute nutrients and oxygen, and also dump waste byproducts (eg: carbon dioxide) out of the body. So choice C is the third and final answer.
An example of a muscle that's voluntary are the biceps. You can flex these muscles, and move them around at will. For example, when you pick up an item. So this allows us to rule out choice D.
I'm not sure why your teacher listed "brain". It has properties related to muscles such as the idea of practicing a topic to help retain it (similar to exercising to stay in shape); however, the brain itself isn't a muscle on a technical biological level.
--------------------
Extra info:
Some more involuntary muscles are:
The diaphragm muscle to help the lungs expand and contract (to breathe in oxygen or exhale carbon dioxide).The muscles that allow your eyes to blink. The technical name for them isn't coming to mind at the moment. These muscles blink at some fairly random yet consistent rate, and also blink whenever something like dust particles enter the eye (or threaten to).At some level, you could argue that the biceps are involuntary in some way. What I mean by this is that there's a reflex action to them that is automatically controlled. However, for the most part, the biceps are voluntary muscles.Explanation needed with the answer

A rectangle prism with a higher of 1.8 inches and a length of 4.2 inches has a volume of 26.46 cubic inches. What is the width of the prism?
9514 1404 393
Answer:
3.5 inches
Step-by-step explanation:
The volume is given by the formula ...
V = LWH
Filling in the given values, we can solve for the remaining dimension.
26.46 in³ = (4.2 in)(W)(1.8 in)
W = 26.46 in²/(7.56 in²) = 3.5 in
The width of the prism is 3.5 inches.

Find the point on the y-axis that is 7 units from the point
(−7, −4).
(x, y) =
Answer:
-7,3
Step-by-step explanation:
The point on y - axis has coordinates = (0, -4)
We have a point whose coordinates are - P(-7, -4)
We have to find the point on the y-axis that is 7 units from the point.
What is the formula to find the distance between the two points on Cartesian plane ?The distance between two points -
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
According to the question, we have -
Coordinates of Point : P(-7, -4)
Since the other point is on y - axis, therefore its x - coordinate will be 0.
Let the point on y - axis have coordinates as - (0, k).
Using the formula discussed above -
7 = [tex]\sqrt {\left( {-7- 0} \right)^2 + \left( {-4 - k } \right)^2 }[/tex]
49 = [tex](-7)^{2}[/tex] + [tex](-4-k)^{2}[/tex]
[tex](-4-k)^{2}[/tex] = 0
[tex](k + 4)^{2}[/tex] = 0
Solve the quadratic equation, you will get -
k = -4
Hence, the point on y - axis has coordinates = (0, -4)
