Answer:
[tex]\sf y = 3.17[/tex]
explanation:
[tex]\sf y * y * y = 32[/tex]apply rule: a * a * a = a³
[tex]\sf y^3= 2^5[/tex]changing sides, changes cubic to cubic root
[tex]\sf y = \sqrt[3]{2^5}[/tex]simplify
[tex]\mathrm \huge {y = 2^{\frac{5}{3} }}[/tex]In decimals
[tex]\sf y = 3.174802104[/tex]In two decimal places
[tex]\sf y = 3.17[/tex]Solution:
Note that:
y × y × y = y³ = 32Taking a cube root both sides.
y³ = 32=> ∛y³ = ∛32Writing the prime factors of 32.
=> y = ∛2 x 2 x 2 x 2 x 2Simplifying ∛32
=> y = 2 x ∛2 x 2 = 2 x ∛4PLEASE HELP AND SHOW WORK

Over a 14-day period, Jamal went to the store 4 times. Based on this
information, which statement best describes how many times Jamal will go
to the store in a 5-week period?
Answer:
He will go to the store 10 times in a 5-week period.
Step-by-step explanation:
We can assume that in one week, Jamal went to the store 2 times, considering he went to the store 4 times in 2 weeks. Next, we can assume that he will go to the store 10 times in 5 weeks, since 2×5=10.
The area of a parallelogram is 91.2cm2, base is l2cm. Find its height.
Answer:
7.6 cm
Step-by-step explanation:
The formula to find the area of the parallelogram is :
Area = Base × Height
They have already given,
Area = 91.2 cm²
Base = 12 cm
Height =?
To find the height, let the height be h.
Let us solve it now.
Area = Base × Height
91.2 cm² = 12 cm × h
Divide both sides by 12.
7.6 cm = h
Therefore, the height is 7.6 cm.

Here , We have to create a real life problem which is based on the similar traingle.
Before creating a real life problem . It is important that you should know the basics of the theorem related to similar triangle .Triangles are similar when their corresponding angles are equal and corresponding sides are in proportion.There are three conditions that proves the given triangles are similar :-
If the corresponding angles of the both the triangles are equal . Then the two triangles are similar to each other known as AA or AAA criterionIf the two sides and one angle of both the triangle are equal to each other . Then the two triangles are similar to each other known as SAS criterion If all the three sides of both the triangle are equal or having same ratios then both the triangle are similar to each other known as SSS criterion. Let's Come to the real life problemSuppose your teacher told you that the two apple trees in a school garden are similar to each other. Now, you are curious to know why both the trees are similar to each other. you have asked the same question to your teacher, She told you to work on the similar traingles theorem .
Solution :-Let consider both the apple trees as tree 1 and tree 2
Given :-The height of the tree 1 is 20 m and height of the tree 2 is 40 mThe shadow casted by both the trees, Tree 1 = 12 m and tree 2 = 24 mThe distance between the height and shadow of both the trees, Tree 1 = 30 m and Tree 2 = 60 mBy using similarity theorem
It states that two triangles are similar when the corresponding sides of both the triangles are in proportion or the corresponding angles of both the triangles are equalThat is,
[tex]\sf{\dfrac{ 20}{40}}{\sf{ = }}{\sf{\dfrac{12}{24}}}{\sf{=}}{\sf{\dfrac{ 30}{60}}}[/tex]
[tex]\sf{\dfrac{ 1}{2}}{\sf{ = }}{\sf{\dfrac{1}{2}}}{\sf{=}}{\sf{\dfrac{ 1}{2}}}[/tex]
From above we can conclude that,
Both the apple trees are similar to each other because all the three sides of both the apple trees are in proportion.
The conclusion is that both of the Orange trees are similar to each other because all the three sides of both the Orange trees are in proportion.
How to Solve Similarity Theorem?Let consider both the Orange trees as tree 1 and tree 2
If we have:-
Height of the tree 1 = 20 m
Height of the tree 2 = 40 m
The shadow casted by Tree 1 = 12 m
The shadow casted by tree 2 = 24 m
The distance between the height and shadow of Tree 1 = 30 m.
The distance between the height and shadow of Tree 2 = 60 m
By using triangle similarity theorem, we have;
20/40 = 12/24 = 30/60 = 1/2

Sally can paint a room in 5 hours while it takes Steve 7 hours to paint the same room. How long will it take them to paint the room if they work together?
(Type an integer or decimal rounded to one decimal place as needed)
=====================================================
Explanation:
Let's say the room has walls and ceiling of 350 sq ft in total area.
Sally can paint this area in 5 hours when working alone, so her unit rate is 350/5 = 70 sq ft per hour.
Steve needs 7 hours to do the same job when working alone, so his unit rate is 350/7 = 50 sq ft per hour.
Assuming the two people can work together without hindering each other (i.e. without getting in each other's way), then the two unit rates combine to 70+50 = 120 sq ft per hour.
Divide the total area over this combined unit rate
350/120 = 2.91667 approximately
This rounds to 2.9
--------------
Alternatively, you can solve the equation
[tex]\frac{1}{5} + \frac{1}{7} = \frac{1}{x}[/tex]
And you should get roughly x = 2.9

What is the perimeter of a square if it has an area of 10 sq. cm.
Answer: [tex]4\sqrt{10}[/tex] cm
Step-by-step explanation:
The area of the square is equal to the side length^2.
We can let s be the length of the side.
Therefore, s^2 = 10 cm^2
Square root both sides:
s = [tex]\sqrt{10}[/tex] cm
The perimeter of a square is 4 multiplied by the side length.
Therefore, the perimeter of the square is 4s = [tex]4\sqrt{10}[/tex] cm

Which of the following values for x and y make the equation 4x + 2y + 3 = 19 true?
x=5, y = 3
x = 4, y = 5
x = 3, y = 2
x = 2, y = 5
Solution:
Option A
4x + 2y + 3 = 19=> 4(5) + 2(3) + 3 = 19=> 20 + 6 + 3 = 19=> 29 = 19 (False)Option B
4x + 2y + 3 = 19=> 4(4) + 2(5) + 3 = 19=> 16 + 10 + 3 = 19=> 29 = 19 (False)Option C
4x + 2y + 3 = 19=> 4(3) + 2(2) + 3 = 19=> 12 + 4 + 3 = 19=> 19 = 19 (True)Option D
4x + 2y + 3 = 19=> 4(2) + 2(5) + 3 = 19=> 8 + 10 + 3 = 19=> 21 = 19 (False)Option C is correct.
Answer:
5
Step-by-step explanation:
Part A: 4 x 6 = 24 - 5 = 19 = 19, and v= is equal to or less than. Because 19 is the same as 19, saying it is larger than is false.
Part B (of two):
The answer is incorrect: 4 x 4 = 16 + 3 = 19 = 23.
20 + 3 = 23 = 23 = 4 x 5 = 20 x 5 = 20 x 5 = 20 x 5 = 20 x True, but we should also consider the other possibilities.
Incorrect: 4 x 6 = 24 + 3 = 27 = 23
Incorrect: 4 x 7 = 28 + 3 = 31 = 23
Incorrect: 4 x 8 = 32 + 3 = 35 = 23
As a result, 5 is the correct response!
