Jen dug 42 dandelions out of the lawn and was paid 5 cents per plant. The preius satuarday she dug 60 plants and the satuarday before she dug 33 dandelions. On average how many plants did she dig each week.
Answer:
On average, she digs 45 plants per week
Step-by-step explanation:
Here, we have the number of plants dug in every saturday for three weeks
we now want to get the average of the three weeks
We proceed to add up all what has been dug in the three weeks and divide by 3
Mathematically, that would be;
(42 + 60 + 33)/3 = 135/3 = 45

Jordan uses 1/4 of the 31/2 yards of fabric she has to make a top. How many yards did she use?
The fabric left is 2 1/4 yards which is calculated using subtraction.
Total fabric = 3 1/2 = 7 / 2 yards
Used fabric = 1 / 4 yards
Fabric left will be calculated using subtraction.
So, we get that:
Left fabric = 7 / 2 - 1 / 4
= 14 / 4 - 1 / 4
= 13 / 4
= 2 1/4 yards.
Therefore, we get that, the fabric left is 2 1/4 yards which is calculated using subtraction.

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 100 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run? Round your answer to the nearest cm
Answer:
Chubby ran a distance of 6,283 m
Step-by-step explanation:
The length of one run is simply equal to the circumference of the circle
Mathematically, C = pi * d
C = 22/7 * 20 = 62.83 cm
So if one rotation is a distance of 62.83 cm, then 100 rotations will be a distance of;
62.83 * 100 = 6,283 m

Answer: 718.38 units³
Step-by-step explanation:
Formula for volume of a cone:
V = πr²•h/3
You have the following information given:
r = 7
h = 14
Plug your values in:
V = π(7)²•(14)/3
V = 718.38 units³
BUT since your instructions say to enter only the number, your answer is just 718.38 with no units after it.
Hope this helps! :)

The morning announcements said that two out of every seven sixth-grade students in the school have an overdue library book. Jasmine said, “That would mean 24 of us have overdue books!” Grace argued, “No way. That is way too high.”
How can you determine who is right?
Answer:
We need to know how many students are in sixth grade and compare the real number with the 84 sixth graders that Jasmine claims to be.
Step-by-step explanation:
We would need to know how many students are in sixth grade to determine who is right. If two students out of seven have an overdue library book and grace claims that 24 of them are overdue by that means, what we would need to do is divide the allegedly 24 students between 2. Now we have 12 pairs of students that have overdue books. For every pair of students in sixth grade that have overdue books, seven students don’t have overdue books, so now we multiply 12 pairs of students with overdue books times 7 students who don’t have overdue books. By Jasmine calculation then, sixth grade have 84 students.
If sixth grade have indeed 84 students, Jasmine is right. If there are not 84 students in sixth grade, she is wrong. Grace is right if there are fewer students than 84 in sixth grade.

use the fact that 2 1/2 divide 1/8 =20 to find 2 1/2 divide 5/8
Answer:
4
Step-by-step explanation:
Given that [tex]2\frac 1 2 \div \frac 1 8 =20[/tex]
[tex]\Rightarrow \frac 5 2 \div \frac 1 8 =20[/tex]
[tex]\Rightarrow \frac 5 2 \times 8 1 =20 \cdots(i)[/tex]
Now, [tex]2\frac 1 2 \div \frac 5 8[/tex] [tex]= \frac 5 2 \div \frac 5 8[/tex][tex]=\frac 5 2 \times \frac 8 5[/tex]
This can be written as
[tex]\frac 5 2 \times \frac 8 5=\frac 5 2 \times \left( \frac 8 1 \times \frac 1 5\right)[/tex] [as [tex]\frac 8 5=\frac 8 1 \times \frac 1 5[/tex]]
[tex]=\left(\frac 5 2 \times \frac 8 1 \right)\times \frac 1 5[/tex]
[tex]=20 \times \frac 1 5[/tex] [ by using equation (i)]
=4
Hence, [tex]2\frac 1 2 \div \frac 5 8=4[/tex]

The given set ℤ can be written as {..., -3, -2, -1, 0, 1, 2, 3, ...}.
The given set ℤ can be written as { x | x is an integer, -∞ < x < ∞}.
Disclaimer:
I assume that ℤ in the question indicates the set of all integers.
Sets are the basis of mathematics. One can write sets in different ways and form smaller sets of elements from a larger set.
Any set can be written in two forms.
Roster formSet-builder notationRoster form:
Roster form is one way to write sets. The roster form lists the elements of a set within braces, { }. Let's see a few examples for the roster form.
We write the set containing the elements 5, 6, 7, and 8 as {5, 6, 7, 8}We write the set of multiples of 5 as {5, 10, 15, 20, 25, 30,...}.So, the given set ℤ can be written as {..., -3, -2, -1, 0, 1, 2, 3, ...}
Set-builder notation:
Set-builder notation is another way to write sets. Set-builder notation describes by enumerating its elements or stating the properties that its elements must satisfy. Let's see a few examples for the set-builder notation.
We write the set containing the elements 5, 6, 7, and 8 as { x | x is a natural number, 4 < x < 9}We can write the set of multiples of 5 as { x | x is a multiple of 5}. This is read as "the set of all real numbers x, such that x is a multiple of 5".So, the given set ℤ can be written as { x | x is an integer, -∞ < x < ∞}. This is read as "the set of all real numbers x, such that x is an integer".

Step-by-step explanation:
75x + -300 = 25x + 200
Reorder the terms:
-300 + 75x = 25x + 200
Reorder the terms:
-300 + 75x = 200 + 25x
Solving
-300 + 75x = 200 + 25x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-25x' to each side of the equation.
-300 + 75x + -25x = 200 + 25x + -25x
Combine like terms: 75x + -25x = 50x
-300 + 50x = 200 + 25x + -25x
Combine like terms: 25x + -25x = 0
-300 + 50x = 200 + 0
-300 + 50x = 200
Add '300' to each side of the equation.
-300 + 300 + 50x = 200 + 300
Combine like terms: -300 + 300 = 0
0 + 50x = 200 + 300
50x = 200 + 300
Combine like terms: 200 + 300 = 500
50x = 500
Divide each side by '50'.
x = 10

How to write the expression as a number in scientific notation?The expression is given as:
quantity 7 times 10 cubed end quantity times quantity 5.4 times 10 to the fourth power end quantity all divided by quantity 9 times 10 squared
Rewrite properly as:
[7 * 10^3 * 5.4 * 10^4]/[9 * 10^2]
Evaluate the product of 7 and 5.4
So, we have:
[37.8* 10^3 * 10^4]/[9 * 10^2]
Evaluate the product of 10^3 and 10^4
So, we have:
[37.8* 10^7]/[9 * 10^2]
Evaluate the quotient of 37.8 and 9
So, we have:
[4.2 * 10^7]/[10^2]
Evaluate the quotient of 10^7 and 10^2
So, we have:
