A grocery store sells a bag of 4 lemons for $0.79. Which pricing option would result in the same unit price for each lemon?
O A. twelve lemons for $2.37
O B. three lemons for $0.65
O C. six lemons for $1.20
OD two lemons for $0.35
Plz help for 20 points
Answer:
.79/4= .197. Or 20 cents each
The cost per unit of lemon in Option A is same as given per unit cost of lemon in grocery store that is $0.1975
What is cost per unit?Cost of per unit is cost of one unit. Cost per unit can be calculated simply by dividing the total cost of all items by the quantity of given item.
Given Cost of 4 lemons in a grocery store = $ 0.79
Cost of 1 lemon in the grocery store = total cost / 4 = $ 0.79÷ 4 = $0.1975
To check pricing option for same pricing check per unit price of each option.
A. Given twelve lemons for $2.37
Given Cost of 12 lemons = $ 2.37
Cost of 1 lemon = total cost / 12 = $ 2.37 ÷ 12 = $0.1975
B. Given three lemons for $0.65
Given Cost of 3 lemons = $ 0.65
Cost of 1 lemon = total cost / 3 = $ 0.65 ÷ 3 = $0.2167
C. Given six lemons for $1.20
Given Cost of 6 lemons = $1.20
Cost of 1 lemon = total cost / 6 = $ 1.20 ÷ 6 = $0.2
D. Given two lemons for $0.35
Given Cost of 2 lemons = $0.35
Cost of 1 lemon = total cost / 2 = $ 0.35 ÷ 2 = $0.175
Therefore , option A has same per unit cost $0.1975 as given pricing of the grocery store.

The value of x is 37.36
Step-by-step explanation:
The given triangle is a right-angled triangle where
Base = 25
Angle = 48°
Hypotenuse = x
As the triangle is a right angled triangle, trigonometric ratios can be used to find the missing value. We can use a ratio which uses base and hypotenuse.
[tex]cos\ 48 = \frac{base}{hypotenuse}\\cos\ 48 = \frac{25}{x}\\0.6691 = \frac{25}{x}\\x = \frac{25}{0.6691}\\x = 37.36[/tex]
Hence ,
The value of x is 37.36

Step-by-step explanation:
Water makes up about 71% of Earth's surface, while the other 29% consists of continents
and islands. 96% of all Earth's water is contained within the oceans as salt water, while the
remaining 4% is fresh water located in lakes, rivers, glaciers, and the polar ice caps.
If the total volume of water on Earth is 1,386 million cubic kilometers, what is the volume
of salt water? What is the volume of fresh water?
Answer:
1330.56
Step-by-step explanation:
96 percent of 1386 is 1330.56
Answer:
Step-by-step explanation:
The question gives you numbers that you don't need to answer the question.
Salt water = 96/100 * 1,386 * 10^6 million km = 0.96 * 1386 * 10^6 = 1330560000 = 1.33056 * 10^9
You can find the fresh water amount by subtracting from 1385 * 10^6 which gives 1386 * 10^6 - 1.33056 * 10^9 = 55 440 000 cubic km

The base of a triangle is 4 cm greater than the height the area is 30 cm² find the height and the length of the base
Answer:
answer is 15 cm²
plz give me the brainliest
Answer:
height = 6 cm
Base = 10 cm
Step-by-step explanation:
Let height = h cm
Base = h + 4
Area of triangle = 30 cm²
[tex]\frac{1}{2}bh = 30\\\\\frac{1}{2}*( h + 4) *h = 30\\[/tex]
Multiply the equation by 2
(h + 4) * h = 30*2
h*h + 4*h = 60
h² + 4h = 60
h² + 4h - 60 = 0
Product = -60
Sum = 4
Factors = 10, (-6)
h² + 10h - 6h - 6 * 10 = 0
h(h + 10) - 6(h + 10) = 0
(h +10)(h - 6) = 0
{Ignore h + 10 = 0 because measurements will not be in negative}
h - 6 = 0
h = 6 cm
b = 6 + 4 = 10 cm

If you can walk 5.3 miles in 2.5 hours, how many minutes does it take to walk 3.18 miles? Round to 1 decimal.
Answer:
90min
Step-by-step explanation:
we can solve the first part by means of the rule of three:
5.3miles ----2.5 hour
3.18miles----x
then
[tex]x=\frac{3.18*2.5}{5.3} \\x=\frac{7.95}{5.3} \\x=1.5 hours[/tex]
Now we must convert hours to minutes:
1.5 hours = 1.5hours (1)
1.5 hours =1.5 hours [tex]\frac{60min}{1 hours}[/tex]
1.5 hours =(1.5)(60) min
1,.5 hours =90min

Step-by-step explanation:
Maclaurin series is:
∑ₙ₌₀°° f⁽ⁿ⁾(0) xⁿ / n!
Find the nth derivative and evaluate at x=0:
f(x) = e⁻³ˣ
f⁽ⁿ⁾(x) = (-3)ⁿ e⁻³ˣ
f⁽ⁿ⁾(0) = (-3)ⁿ
The Maclaurin series is therefore:
∑ₙ₌₀°° (-3)ⁿ xⁿ / n!
∑ₙ₌₀°° (-3x)ⁿ / n!
Use ratio test to find the radius of convergence.
lim(n→∞)│aₙ₊₁ / aₙ│< 1
lim(n→∞)│[(-3x)ⁿ⁺¹ / (n+1)!] / [(-3x)ⁿ / n!]│< 1
lim(n→∞)│(-3x) n! / (n+1)!│< 1
lim(n→∞)│3x / (n+1)│< 1
0 < 1
The radius of convergence is infinite.

Minimize F = 3a + 4m if ma = 12. Assume a > 0, m > 0.

Answer:
Min value of F = 24
It happens when m = 3 and a = 4.
==========================================================
Explanation:
Start with ma = 12 and Solve for 'a' to get a = 12/m
Plug it into the other equation to get
F = 3a + 4m
F = 3(12/m) + 4m
F = 36/m + 4m
F = 36/m + (4m^2)/m
F = (36+4m^2)/m
The equation above is in the form F = a/b where a = 36+4m^2 and b = m
Applying derivatives to each piece gives a' = 8m and b' = 1
So,
F = a/b
F ' = (a/b)'
F ' = (a' * b - a * b')/(b^2) .... quotient rule
F ' ( 8m*m - (36+4m^2)*1 )/(m^2)
F ' = (8m^2 - 36 - 4m^2)/(m^2)
F ' = (4m^2 - 36)/(m^2)
---------------------
The minimum of F occurs when F ' = 0
F ' = 0
(4m^2 - 36)/(m^2) = 0
4m^2 - 36 = 0*m^2
4m^2 - 36 = 0
4m^2 = 36
m^2 = 36/4
m^2 = 9
m = sqrt(9) or m = -sqrt(9)
m = 3 or m = -3
Keep in mind that m > 0, so we ignore m = -3
---------------------
Next we'll use the first derivative test. I find it's easier compared to the second derivative test because we don't have to do another derivative.
The function F(m) = (36+4m^2)/m has a potential min point at m = 3.
To see if we have an actual min point or not, we need to check the sign of F ' (m) when m = 2 and m = 4; that way we see if F ' (m) changes sign as we pass through m = 3.
First compute the derivative when m = 2
F ' (m) = (4m^2 - 36)/(m^2)
F ' (2) = (4(2)^2 - 36)/(2^2)
F ' (2) = (4*4-36)/(4)
F ' (2) = (16-36)/(4)
F ' (2) = -20/4
F ' (2) = -5
The actual value doesn't matter. All we're after is the sign of it. So we see that F ' (2) is negative which means we know that F(m) is decreasing when 0 < m < 3
Now let's try m = 4
F ' (m) = (4m^2 - 36)/(m^2)
F ' (4) = (4(4)^2 - 36)/(4^2)
F ' (4) = (4*16-36)/(16)
F ' (4) = (64-36)/(16)
F ' (4) = 28/4
F ' (4) = 7
This value is positive, so F(m) is increasing on the interval 0 < m < infinity
F(m) decreases on 0 < m < 3 and increases on 3 < m < infinity
So the F function goes downhill and then goes back uphill, and this lowest valley point is when m = 3
So we've confirmed that F(m) does indeed have a min value at m = 3.
Making a sign chart or interval might help visualize it.
---------------------
Now onto the last part.
Plug m = 3 into F(m) to find the min value of F
F = (36+4m^2)/m
F = (36+4*3^2)/3
F = (36 + 4*9)/3
F = (36 + 36)/3
F = 72/3
F = 24
The smallest F can get is 24 and it happens when m = 3 and a = 12/m = 12/3 = 4.
------------------------------
Side note: A non-calculus approach would have you graphing y = (36+4x^2)/x, and then using the graphing calculator to find the lowest point in the first quadrant. We're in this quadrant since a, m and F are all positive.

in jacks class 18 of the students are tall and 10 are short. in Michaels class 54 students are tall and 30 students are short. which lass has a higher ratio of tall to short students
Answer:
uhh what kinda class is that big- anyways
Step-by-step explanation:
jacks class
18:10
If you divide 18 by 10 you get 1.8
Micheals class
54:30
If you divide 54 by 30 you get 1.8
therefore neither. They are both equivalent
the Ratio of tall to short students in the Michels and jacks class is equal which is 1.8.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, in jacks class 18 of the students are tall and 10 are short. in Michaels's class, 54 students are tall and 30 students are short.
The ratio of tall to short students in jacks class = 18/10 = 1.8
The ratio of tall to short students in Micheals's class = 54/30
The ratio of tall to short students in Micheals's class = 1.8
Therefore, the Ratio of tall to short students in the Michels and jacks class is equal which is 1.8.
