Answer:
E. The price will be quoted in euros per kilogram because the price is quoted in currency per weight
Step-by-step explanation:
The price will be quoted in euros per kilogram because the price is quoted in currency per weight
Currency in Europe is Euro
Apple have weight
Volume of apple is measured in kilogram
For instance, if the person is buying 10 kilograms of apples for 20 Euro.
Then the price per kilogram = 20/10
=2 Euro per kilogram
O Sr. Lima investiu R$5000,00 em um fundo de ações. No 1º ano as ações do fundo valorizaram-se 35%; no 2º ano, valorizaram-se 20% (em relação ao 1º ano) e no 3º ano desvalorizaram-se 30% (em relação ao 2º ano). Que valor o Sr. Lima terá ao final dos três anos? a) R$ 10.530,00 b) R$ 5.670,00 c) R$ 6.853,00 d) R$ 7.500,20 e) R$ 8.320,40
Responda :
R $ 10.530
Explicação passo a passo:
Investimento inicial = R $ 5.000
Apreciação no primeiro ano = 35%
Apreciação no segundo ano = 20% em relação ao primeiro ano
Valorização no terceiro ano = 30% em relação ao segundo ano
Se o investimento se valorizar em 35% no primeiro ano:
35% do investimento: 0,35 × R $ 5.000 = R $ 1.750
Total após o primeiro ano = R $ (5.000 + 1.750) = R $ 6.750
2º ano:
Valorização de 20% em relação ao primeiro ano:
20% de 6750 = 0,20 * 6750 = R $ 1.350
Total = (6.750 + 1.350) = R $ 8.100
3 º ano:
Valorização de 30% em relação ao segundo ano:
30% de 8100 = 0,30 * 8100 = R $ 2.430
Total = (8.100 + 2.430) = R $ 10.530
No final do terceiro ano:
R $ 10.530

A kid has 8 more quarters than dimes. The total number of coins is 20.
a. 8 quarters 16 dimes
b. 6 dimes and 14 quarters
c. 6 quarters 14 dimes
d. d + (d + 8) = 20
e. 10 quarters and 10 dimes
f. d + 8 = 20
g. 8d = 20
Answer:
b. 6 dimes and 14 quartersd. d + (d + 8) = 20Step-by-step explanation:
If we let d represent the number of dimes, then d+8 represents the number of quarters. The total number of coins is the sum of the numbers of each:
d +(d +8) = 20 . . . . . matches choice d
Collecting terms, we have ...
2d +8 = 20
d +4 = 10 . . . . . divide by 2
d = 6 . . . . . . . . subtract 4
The kid has 6 dimes and 14 quarters. (matches choice b)
a jar has 5 tablespoons of honey in it. One serving of Honey is 3/4 of a tablespoon. how many servings of honey are in the jar.
Servings = total amount / serving size
Servings = 5 / 3/4
When dividing by a fraction, reverse the fraction and multiply:

= 20/3
= 6 2/3 servings
Answer: 6 servings
Step-by-step explanation:
3/4+3/4+3/4+3/4+3/4+3/4=4.5
if you add 3/4 then it will be 5.25 so basically 5 tablespoons
it is 6 full servings
Estelle is raking leaves in her yard. After 1 hour, she has 2 bags of leaves. After 3 hours, she has 6 bags of leaves. Which graph represents Estelle's leaf raking progress? (2 points)
Answer:
You're looking for the graph [tex]y=2x[/tex]
Step-by-step explanation:
If Estelle is raking in leaves at a constant rate, which we usually assume for cases like this, we're looking for a function of the form
[tex]y=kx+m[/tex]
x here is going to be the number of hours, or time.
y is going to be the number of bags she has raked in.
First of all, we know that at time 0, she hasn't raked in any leaves. So when x is 0, we know y is 0. Let's put these values in our function.
[tex]0 = k * 0 + m[/tex]
[tex]0 = 0 + m[/tex]
[tex]m = 0[/tex]
We now know m is 0.
We also know that after 1 hour, Estelle has 2 bags of leaves. So when x is 1, y will be 2. Let's put these values in.
[tex]2 = k*1[/tex]
We're excluding m as we know it's 0.
[tex]k=2[/tex]
So k is 2, and m is 0. Let's put these values in our original function [tex]y=kx+m[/tex]:
[tex]y = 2x + 0[/tex]
[tex]y=2x[/tex]
The equation is y=2x.
Putting this into a graphing calculator, we get this graph (attached).

Why are (1,2) and(2,1) not equal ordered pair?
Answer:
The pairs ( 1 , 2 ) and ( 2 , 1 ) are not equal because their respective elements are not equal.
Step-by-step explanation:
The pair of elements which are in specific order is called an ordered pair. The pair ( 1 , 2 ) is not same as the pair ( 2 , 1 ). In the pair ( 1 , 2 ) 1 is in the first position and 2 is in the second position. In the pair ( 2 , 1 ), 2 is in the first position and 1 is in the second position.
Two ordered pairs ( a , b ) and (c , d ) are said to be equal if a = c and b = d. We write ( a , b ) = ( c , d ).

A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost, C, after h hours of service. What will be the total cost for 8 hours of work?
Answer:
C(h) = 50h + 25
$425
Step-by-step explanation:
Et the plumber works for h hours.
Cost of one hour = $50
Therefore, cost of h hours = $50h
Total cost = cost of h hours + plumber service call charge
C(h) = 50h + 25 (required equation)
Plug h = 8
C(8) = 50* 8 + 25 = 400 + 25 = $425

Answer:
Plant B
Step-by-step explanation:
The only measure of variation we really need to check is the mean, or average, of tomatoes that each plant produced. This is because if Kathryn was a farmer, she would want a plant that on average, produces more tomatoes. For that reason, in this context, the mode, median and range are irrelevant. To find the mean of a data set, you simply divide the sum of all of the data by the number of data in the set. Therefore:
Mean of Plant A: (4 + 6 + 7 + 3 + 6 + 2 + 1 + 3 + 6 + 5) / 10 = 43 / 10 = 4.3
Mean of Plant B: (5 + 6 + 7 + 6 + 8 + 9 + 6 + 7 + 8 + 9) / 10 = 71 / 10 = 7.1
As you can see, the mean tomatoes Plant B produces is larger than that of Plant A, therefore, Kathryn should choose Plant B if she was a farmer.

a recipe for chocolate chip cookies calls for 1 1/4 cups of flour. if you are making 2 1/3 recipes, how many cups of flour are needed?
Answer:
2 11/12 cups of flour
Step-by-step explanation:

How do you graph y = √ 5 - x? How do I find the coordinates by hand?
Each point is of the form (x,y). We replace x with some number to get a paired y value.
For instance, if x = 1, then,
[tex]y = \sqrt{5-x}\\\\y = \sqrt{5-1}\\\\y = \sqrt{4}\\\\y = 2[/tex]
Meaning x = 1 and y = 2 pair up. The point (x,y) = (1,2) is on the curve.
Then let's try x = 4
[tex]y = \sqrt{5-x}\\\\y = \sqrt{5-4}\\\\y = \sqrt{1}\\\\y = 1[/tex]
Showing (4,1) is also on the curve.
The point (5,0) is also on the curve too because of the steps below
[tex]y = \sqrt{5-x}\\\\y = \sqrt{5-5}\\\\y = \sqrt{0}\\\\y = 0[/tex]
We can't go any higher than x = 5 or else the expression 5-x will be negative. Eg: if x = 7, then 5-x = 5-7 = -2. We cannot take the square root of a negative and get some real number output.
So let's go in the opposite direction. Let's try x = -4
[tex]y = \sqrt{5-x}\\\\y = \sqrt{5-(-4)}\\\\y=\sqrt{5+4}\\\\y = \sqrt{9}\\\\y = 3[/tex]
Showing (-4,3) is also on the curve.
The x values I'm picking are such that the y value is an integer. For the majority of the x values, you'll get some decimal value which is a bit tricky to graph on paper. So effectively you'll have to use trial and error to find the right x values to pick. The goal is to get the stuff under the square root to simplify to some perfect square (0,1,4,9,...etc)
After generating enough points, you draw a curve through them all. The more points, the more accurate the graph.

An object is moving at a speed of 95 kilometers every 7.5 weeks. Express this speed in
feet per day
Answer:
5,936.76 feet/dayStep-by-step explanation:
Formula to use to get the speed is expressed as speed = Distance/Time
Given parameters
Distance = 94km
Time = 7.5weeks
Since we are to express the answer in feet per day, we will convert the distance to feet and time to days.
For the distance:
Given the conversion
1 km = 3280.84 feet
95km = (95*3280.84)feet
95km = 311,679.8 feet
For the time:
If 1 week = 7 days
7.5weeks = (7.5 * 7)
7.5weeks = 52.5 days
Speed In ft/day = 311,679.8 feet/ 52.5 days
Speed in ft/day = 5,936.76 feet/day
Hence the speed in feet per day is 5,936.76 feet/day

Prime Factor of 84:
84
84 divides by 2 84 = 42 x 2
84 = 2 x 42
42 divides by 2 42 = 21 x 2
42 = 2 x 2 x 21
21 divides by 3 21 = 7 x 3
21 = 2 x 2 x 3 x 7
2, 3, 7 is a prime number, therefore no further factorization is possible = 2 x 2 x 3 x 7

What is h-(-5)=2? And how do you solve it?
Answer:
It is an equation, and the answer is [tex]h = -3[/tex]
Step-by-step explanation:
We have a variable that's equal to a term, so this is an equation.
To solve this, we want to isolate h on one side.
[tex]h - (-5) = 2[/tex]
Subtracting a negative is the same thing as adding a positive:
[tex]h + 5 = 2[/tex]
Now we can subtract 5 from both sides to isolate h.
[tex]h + 5 - 5 = 2-5\\\\h = -3[/tex]
