mark's soup recipe makes 6 servings and uses 4 carrots and 2 potatoes. Drag carrots and potatoes into the box to show how many Mark needs for 15 servings.
Answer:
10 carrots and 5 potatoes
Step-by-step explanation:
If 6 servings uses 4 carrots and 2 potatoes we can determine how many carrots and potatoes must be used per serving.
Lets look at the carrots:
[tex]=4/6=0.67[/tex]
Therefore for 15 servings:
[tex]=0.67×15=10.05≈10[/tex]
Lets look at potatoes:
[tex]=2/6=0.33[/tex]
Therefore for 15 servings:
[tex]=0.33×15=4.95≈[/tex]
Lan pays a semiannual premium of $700 for automobile insurance, a monthly premium of $145 for health insurance, and an annual premium of $450 for life insurance.
the monthly expense is $
Answer:
$300
Step-by-step explanation:
1.automobile insurance : $700 semiannual premium
Annual premium = $700×2=$1400
2.
Health insurance :$145 per month
Annual premium= $145×12=$1740
3. Life insurance: $450 annual
Total annual premium
$1400+$1740+$450=$3590
Hence his monthly expenses on premium =
[tex]\frac{3590}{12}[/tex]

Nancy has nine books and she has read 8 total books Sally has two times more books the Nancy how many books does Sally have
Sally has 18 books, as she has two times more books than Nancy, who has 9 books. The equation used is Sally's books = 2 × Nancy's books. Therefore, 2 × 9 = 18.
To determine how many books Sally has, we need to understand that she has two times more books than Nancy. Nancy has a total of 9 books.
The equation we use here is:
Sally's books = 2 × Nancy's booksGiven Nancy's books = 9:
Sally's books = 2 × 9 = 18Therefore, Sally has 18 books.
the sum of two integers is 9 and the sum of their squares is 53. Find the integers.
A set of scores ranges from a high of x = 96 to a low of x = 11. if these scores were placed in a grouped frequency distribution table, what is the best value for the interval width?
The best value for the interval width is 17
The highest and the lowest data elements are given as:
x = 96
x = 11
Start by calculating the range
Range = High - Low
So, we have:
Range = 96 - 11
Range = 85
The interval width depends on the number of classes.
Assume that the number of classes is 5,
Then the width is calculated as:
Width = Range / Class
So, we have:
Width = 85/5
Width = 17
Hence, the number of interval width is 17

A triangle has side lengths of 14 cm, 48 cm, and 55 cm.
Using synthetic division, find (x4 − 2) ÷ (x + 1).
Answer:
Step-by-step explanation:
We have given:
x^4-2/x+1
Put x+1 = 0
x= 0-1
x= -1
-1 | 1 0 0 0 -2
| -1 1 -1 1
_______________
1 -1 1 -1 -1
Thus it makes the expression:
x^3-x^2+x-1 - 1/x+1
You can further confirm this expression by solving the expression:
(x4 − 2) ÷ (x + 1).
x^4 - 1 -1/x+1
x^4-1/x+1 - 1/x+1
(x^2-1) (x^2+1)/x+1 - 1/x+1
(x-1)(x+1) (x^2+1)/x+1 - 1/x+1
x+1 n the numerator will be cancelled out by x+1 in the denominator.
(x-1) (x^2+1) - 1/x+1
Multiply (x^2+1) by x-1
x(x^2+1) -1(x^2+1) - 1/x+1
x^3+x-x^2-1 - 1/x+1
x^3-x^2+x-1 - 1/x+1 ....

Hence, the mid-point of side EF is located at:
(-0.5,4.5)
Step-by-step explanation:We know that the coordinates of a mid-point C(e,f) of a line segment AB with vertices A(a,b) and B(c,d) is given by:
[tex]e=\dfrac{a+c}{2},\ f=\dfrac{b+d}{2}[/tex]
Here we have to find the mid-point of side EF.
E(-2,3) i.e. (a,b)=(2,3)
and F(1,6) i.e. (c,d)=(1,6)
Hence, the coordinate of midpoint of EF is:
[tex]e=\dfrac{-2+1}{2}\ ,\ f=\dfrac{3+6}{2}\\\\\\e=\dfrac{-1}{2}\ ,\ f=\dfrac{9}{2}\\\\\\e=-0.5\ ,\ f=4.5[/tex]
Hence, the mid-point of side EF is:

What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
We have to given that;
Sandra used benchmark fractions to describe some insects she collected she said the ladybug is about 1/4 inch long and the cricket is about 2/3 inch long.
Here, The length of ladybug = 1/4 inch
And, The length of cricket = 2/3 inch
Now, By comparing we get;
⇒ 1/4 and 2/3
⇒ 3/12 and 8/12
⇒ 3/12 < 8/12
Hence, The length of cricket is longer than ladybug.

The sum of two numbers is 67. The smaller number is 21 less than the larger number. What are the numbers?
The equations are x + y = 67 and x = y + 21. Then the two numbers are 44 and 23.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The sum of the two numbers is 67. The smaller number is 21 less than the larger number.
Let the two numbers be 'x' and 'y' and x > y. Then the equations are given as,
x + y = 67 ...1
x = y + 21 ...2
From equations 1 and 2, then we have
y + 21 + y = 67
2y = 46
y = 23
Then the value of 'x' is given as,
x = 23 + 21
x = 44
The equations are x + y = 67 and x = y + 21. Then the two numbers are 44 and 23.

Find all the zeros of the equation.
-3x^4+27x^2+1200=0
I don't really understand this. Please show me the steps! Thanks!
Final answer:
The zeros of the equation -3x^4+27x^2+1200=0 are x = 16 and x = -25.
Explanation:
To find the zeros of the equation -3x^4+27x^2+1200=0, we can use the quadratic formula. Let's set our equation equal to zero:
-3x^4+27x^2+1200=0
Now, we can use the quadratic formula, which states that for an equation in the form ax^2+bx+c=0, the solutions are given by:
x = (-b ± sqrt(b^2-4ac))/(2a)
Applying this formula to our equation, we get:
x = (-27 ± sqrt(27^2-4(-3)(1200)))/(2(-3))
Simplifying further, we have:
x = (-27 ± sqrt(729+14400))/(-6)
x = (-27 ± sqrt(15129))/(-6)
x = (-27 ± 123)/(-6)
So the two solutions are:
x = (-27 + 123)/(-6) = 16
x = (-27 - 123)/(-6) = -25
If 5/9 of a tank can be filled in 2 minutes, how many minutes will it take to fill the whole tank ?
If 5/9 of a tank can be filled in 2 minutes, it would take 3.6 minutes to fill the whole tank by setting up a proportion and solving for the time.
Explanation:If 5/9 of a tank can be filled in 2 minutes, then to find the time it takes to fill the whole tank, we can set up a proportion. Since time is directly proportional to the amount of the tank filled, we have the following relationship:
Fraction of tank filled / Time to fill that fraction = 1 (whole tank) / x minutes
So, 5/9 of the tank is to 2 minutes as 1 whole tank is to x minutes:
(5/9) / 2 = 1 / x
Cross-multiplying gives us:
5x = 18
Dividing both sides by 5:
x = 18/5
x = 3.6 minutes
Therefore, it would take 3.6 minutes to fill the whole tank.
Final answer:
To find out how long it takes to fill the entire tank, set up the proportion of (5/9) of the tank in 2 minutes to (9/9) of the tank in x minutes, which gives x = 3.6 minutes for the whole tank to be filled.
Explanation:
If 5/9 of a tank can be filled in 2 minutes, we can set up a direct proportion to find out how long it would take to fill the entire tank. We are trying to find the time required to fill 9/9 (or the whole tank) if 5/9 takes 2 minutes. To solve this, we calculate:
Set up the proportion where the fraction of the tank filled is directly proportional to the time taken: (5/9) / 2 = (9/9) / x minutes.
Now we solve for x, which represents the total time to fill the tank: x = (2 minutes * 9/9) / (5/9).
Simplify the right side: x = 2 minutes * (9/5).
Calculate the value of x: x = 3.6 minutes.
Therefore, it will take 3.6 minutes to fill the entire tank.
