On Sunday, Sheldon bought 4 1/2 kg of plant food. He used 1 2/3 kg on his strawberry plants and used 1/4 kg for his tomato plants. How many kilograms of plant food did Sheldon have left? Which number sentence matches the problem? *
1 point
Answer:
[tex]2\frac{7}{12}[/tex] kg of plant food
Step-by-step explanation:
The second question doesn't have choices, so I'll answer the first question only.
In order to know how much plant food Sheldon has, you have to subtract [tex]1\frac{2}{3}[/tex] kg of plant food used for the strawberry plants from [tex]4\frac{1}{2}[/tex] kg of plant food. Then, [tex]\frac{1}{4}[/tex] kg will be subtracted from the difference.
[tex]4\frac{1}{2}[/tex] - [tex]1\frac{2}{3}[/tex] = ?Let's convert both fractions into improper fractions first, so it will be easier to subtract.
[tex]4\frac{1}{2}[/tex] = [tex]\frac{9}{2}[/tex][tex]1\frac{2}{3}[/tex] = [tex]\frac{5}{3}[/tex]Now, let's subtract.
[tex]\frac{9}{2}[/tex] - [tex]\frac{5}{3}[/tex] = [tex]\frac{17}{6}[/tex] or [tex]2\frac{5}{6}[/tex] kg of plant foodNext, you have to subtract [tex]\frac{1}{4}[/tex] kg of plant food used for the tomato plants from the remaining plant food of [tex]\frac{17}{6}[/tex] kg.
Let's subtract again.
[tex]\frac{17}{6}[/tex] - [tex]\frac{1}{4}[/tex] = [tex]2\frac{7}{12}[/tex] kg of plant foodTherefore, Sheldon has [tex]2\frac{7}{12}[/tex] kg of plant food left.
A rectangle or field is 62 m long and 48 m wide Diana estimate the length of the field to be 60 m and the ways to be 45 m what is the percent error of Dianas estimated area measurement round your answer to the nearest whole percent
Answer:
To make estimates, we usually round the numbers the nearest integer.
Since 1.9 is closest to 2 than it is to 1, the nearest integer of 1.9 is 2.
Similarly, since 4.4 is closest to 4 than it is to 5, the nearest integer of 4.4 is 4.
Now, to estimate the area of the farm, we are going to multiply our two integers:
Estimated Area of the Farm= x
Since 8 is between 4 and 10, we can conclude that the best estimate of the area of the farm is: between 4 and 10
Step-by-step explanation:
factor 15x + 30y plz show work
Answer:
60
Step-by-step explanation: Simplifying
15x + 30y = 60
Solving
15x + 30y = 60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-30y' to each side of the equation.
15x + 30y + -30y = 60 + -30y
Combine like terms: 30y + -30y = 0
15x + 0 = 60 + -30y
15x = 60 + -30y
Divide each side by '15'.
x = 4 + -2y
Simplifying
x = 4 + -2y
Answer:
15 ( x + 2y)
Step-by-step explanation:
First 15x + 30y
(3x5)x + (2 x 3 x 5)y
3 x 5 (3x5x/3x5 + 2 x 3 x 5y/3x5)
3 x 5 (x + 2y)
15 (x + 2y)

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 2, and the given zeros. -4,0,2,4
Answer:
A least degree polynomial, having rational coefficients and a leading coefficient of 2, with,-4, 0, 2, and 4 as the zeros of the polynomial is;
f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x
Step-by-step explanation:
The given parameters of the polynomial are;
The leading coefficient of the polynomial = 2
The zeros of the polynomial = -4, 0, 2, 4
We note that zeros of -4, and 4 gives a factor of the form, (x² - 4²)
For a zero of the polynomial equal to 0, one of the factors of the polynomial is equal to 'x'
To have a leading coefficient of 2, we can add '2' as a factor of the polynomial
Therefore, we can have the factors of the polynomial as follows;
(x² - 4²)·2·x×(x - 2) = 0
From the above equation, using a graphing calculator, we get the following possible polynomial;
(x² - 4²)·2·x×(x - 2) = 2·x⁴ - 4·x³ - 32·x² + 64·x = 0
Therefore, a polynomial, function of least degree that has rational coefficients, a leading coefficient of 2,and the zeros, -4, 0, 2, and 4 is f(x) = 2·x⁴ - 4·x³ - 32·x² + 64·x.
Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,077 was collected on the
sale of 1,201 tickets. How many of each type of ticket were sold?
The basketball game sold
adult tickets and
student tickets.
Answer:
Your problem will require you setting up 2 algebraic equations. First, you should.
Let A represent the number of adult tickets
Let S represent the number of student tickets
The first equation will be:
A+S = 1,215 tickets
The number of adult tickets plus the number of student tickets equals 1,215 tickets
The second equation will be:
5.00A+1.00S=$2,591
The price and number of adult tickets plus the price and number of student tickets equals $2,591.
I hope this has made the problem easier to understand. I hope you are able to solve the problem from here. If you can not solve the problem from here, I will be more than happy to further assist you.
Step-by-step explanation:
You have two unknowns, two variables, therefore you need to have at least two equations in this word problem in order to find a solution. Let's review the info you are given:
The price of an Adult ticket: $5
The price of a Student ticket: $1
The two variables are: the number of Adult tickets sold (you can use variable "A"), and the number of Student tickets sold (use variable "S").
The other info you are given is the total number of tickets sold: 1,215 tickets. Use this to make your first equation: the number of adult tickets plus the number of student tickets equals 1,215.
You are also told how much money was collected: $2,591. That means, $5 from every Adult ticket and $1 from every student ticket. We don't know how many of each ticket, but we assigned variables A and S to stand in for this unknown info. The money made from all the adult tickets would be the price of the adult ticket times how many adult tickets sold (5 times A), and the money made from all the student tickets would be the price of the student ticket times how many student tickets sold (1 times S). Use this to make your second equation, which says that all the money collected from all the tickets (5 times A in addition to 1 times S) is (=) 2,591.
Now you have two equations, each equation has two variables. To solve, go back to the easiest equation (the first one) and isolate one of the variables. By isolate I mean get it on one side of the equation by itself. Since in this case these variables are being added together, you have to do the opposite of addition, which is of course subtraction. To do this, you will have to subtract the other variable ON BOTH SIDES of the equation. So, say we want to isolate the variable A, we will subtract S from both sides. Well, S minus S is zero, so now A is isolated, meaning the left side of the equation is just A = ... Now you want to subtract the S on the other side. Remember that whatever you do to one side you must do to the other.
Now that you have your equation re-worked to show A = ..., you need to "plug it into" the second equation. What I mean is, you need to substitute instead of A, put in this equation. Then you will have one equation with one variable which you can solve! Remember the rules of equations, to do work in parenthesis first, the multiply or divide, then add or subtract. You will be able to solve for S.
Once you have found S (the number of student tickets sold), you can easily find A (the number of adult tickets sold) by going back to that first equation and subtracting your value of S from 1215.

The depth, d , of a lake is 57 m, rounded to the nearest integer. Write the error interval for d in the form a ≤ d < b .
Given:
The depth, d , of a lake is 57 m, rounded to the nearest integer.
To find:
The error interval for d in the form a ≤ d < b.
Solution:
The depth, d , of a lake is 57 m, rounded to the nearest integer.
If the depths of the lake is 56.5m or greater than this up to 57 m, then the depth, d , of a lake is 57 m, rounded to the nearest integer.
[tex]56.5\leq d\leq 57[/tex] ...(i)
If the depths of the lake is 57m or greater than this up to 57.5 m but not 57.5 m, then the depth, d , of a lake is 57 m, rounded to the nearest integer.
[tex]57\leq d<57.5[/tex] ...(ii)
Using (i) and (ii), we get
[tex]56.5\leq d<57.5[/tex]
Therefore, the error interval for d is [tex]56.5\leq d<57.5[/tex].

Two points in the (x, y) plane are a distance of 5 units apart. After a certain transformation is applied to both points, the two new points are 10 units apart. What was the transformation?
Answer:
translation
Step-by-step explanation:
Based on the information provided the type of transformation would have been a translation of one or both points. This means that either one or both points were moved. If only one point was moved it would have moved 5 units. If both were moved equally then they would have moved 2.5 units apart. Since we are not told the initial and end values of each point we cannot tell if the translation was a vertical or horizontal translation.
