Noah mows 1/2 of his property and leaves the rest wild. He decides to use 1/5 of the weld area for a vegetable garden. What fraction of the property is used for the garden ?
Solving the Question
We're given:
[tex]\dfrac{1}{2}[/tex] of the property was mowed[tex]\dfrac{1}{5}[/tex] of the unmowed property was used for a vegetable gardenWe must first find how much of the property was unmowed.
If [tex]\dfrac{1}{2}[/tex] of the property was mowed, then that leaves [tex]\dfrac{1}{2}[/tex] of the property unmowed.
⇒ [tex]1-\dfrac{1}2}=\dfrac{1}2[/tex]Now, we can find the fraction of the property used for the garden.
[tex]\dfrac{1}5}[/tex] of the [tex]\dfrac{1}2[/tex] of the property was used for the garden. To find this as a fraction, multiply [tex]\dfrac{1}5}[/tex] by [tex]\dfrac{1}2[/tex]:
[tex]\dfrac{1}5*\dfrac{1}2=\dfrac{1}{10}[/tex]
AnswerTherefore, [tex]\dfrac{1}{10}[/tex] of the property was used for the garden.

Francisca has 40 paperbacks in her bookcase. This is 32% of the books in the bookcase. How many books are in Francisca's bookcase? Use an equation with a variable. Show your work
The total number of books that are in Francisca's bookcase is 125 books.
Let the total number of books be B.
Given the following data:
Number of paperbacks = 40.
Percentage = 32%.
How to calculate the total number of books.In this exercise, you're required to determine the total number of books that are in Francisca's bookcase if there she has 40 paperbacks in her bookcase. Thus, we would write a mathematical expression for the word problem.
Translating the word problem into an algebraic expression, we have;
[tex]\frac{32}{100} \times T=40\\\\0.32T=40\\\\T=\frac{40}{0.32}[/tex]

Which is a solution to x + 3 = 2x - 8? 10 11 12
Answer:
x=11
Step-by-step explanation:
Subtract 3 from both sides
x+3=2x-8
x+3-3 =2x-8-3
Then simplify it
x=2x-11
Again, subtract 3 from both sides
x-2x=2x-11-2x
Simplify
-x=-11
Divide both sides and simplify and then you get x=11

How many tiles to cover a floor measuring 24m x 20m if the measure of the tile is 12 cm x 10 cm
Answer:
4 tiles
Step-by-step explanation:
12 * 10 = 120 for each tile
24 * 20 = 480 for entire floor
480/120 = 4
4 tiles
Answer: Below
Step-by-step explanation:
This is a pretty simple problem, so hopefully you catch on to it quickly.
Since we have two measurements for two sides of a rectangle, we know they are referring to square centimeters for both the floor and the tiles. Since the units match up, we can divide.
24 * 20 = 480 cm squared
12 * 10 = 120 cm square.
480/120 = 4 tiles.
Our answer is 4 tiles.
Three hundred high school seniors were surveyed about their intended college majors. The results are displayed in the Venn Diagram below: A Venn Diagram titled College Majors with two circles labeled Math and Science. In the math portion is 120. In the intersection is ??. In the Science portion is 50. The area outside the two circles is labeled 100. If a student is randomly selected from the group, what is the probability that they are majoring in both math and science? Round your answer to the nearest whole percent. 10% 17% 33% 40%.
The probability of selecting one student who is both from math and science is 1/10
There are the total number of student = 300
Out of which,the number of students who are only in Maths = 120
The number of students who are only in Science = 50 and the students who are not from any subject = 100
What is the formula for the total students?
Total no of students=science student+math students +none
Therefore,the number of student who are from both math and science = Total student - Math student (only) - science student (only) - None
= 300 - 120 - 50 - 100
= 30
That is, there are 30 students who are both from science and math,
Thus, the probability of selecting one student who is both from math and science = 30/300 = 1/10

If 3 over 4 ton of pebbles covers 4 over 5 of a garden, how many tons of pebbles are required to cover the entire garden?
3 over 5 ton
15 over 16 ton
1 and 1 over 3 tons
1 and 11 over 20 tons
I am in middle school, I just clicked the wrong button.
Answer:
[tex]\frac{15}{16}[/tex] ton of pebbles will cover the whole garden.
Step-by-step explanation:
So [tex]\frac{3}{4}[/tex] ton covers [tex]\frac{4}{5}[/tex] of the garden.
Let x be pebbles required to cover the entire garden, we can set up a proportion:
[tex]\frac{\frac{3}{4} }{\frac{4}{5} } =\frac{x}{1}[/tex]
[tex]\frac{3}{4}[/tex] / [tex]\frac{4}{5}[/tex] = x
[tex]\frac{3}{4}[/tex] * [tex]\frac{5}{4}[/tex] = x
[tex]\frac{15}{16}[/tex] = x
[tex]\frac{15}{16}[/tex] ton of pebbles will cover the whole garden.
