Jada volunteers at an animal shelter that holds picnics to introduce people to animals. For the first picnic, she brought 36 clementines for 16 people, which was the right amount. For the next picnic, there will be 40 people!
How many clementines should Jada bring for all those people? Explain or show your reasoning.
Jada would have brought 90 clementines for all those people.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
For 40 people number of clementines be x,
So, as for the proportional relationship.
16 / 36 = 40 / x
x = 40 [36/16]
x = 10[9]
x = 90
Thus, Jada would have brought 90 clementines for all those people.

It is recommended that adults consume at least 1,000 mg of calcium every day. One ounce of whole milk contains about 25 mg of calcium, and one ounce of cheddar cheese contains 200 mg of calcium. If a person meets the recommendation by consuming x ounces of whole milk and y ounces of cheddar cheese, then 25x + 200y ≥ 1,000.Give three different amounts of milk and cheese that a person could consume to meet the recommendation.
Answer:
20 ounces of milk and 3 ounces of cheddar cheese
30 ounces of milk and 4 ounces of cheddar cheese
40 ounces of milk and 5 ounces of cheddar cheese
Step-by-step explanation:
Consider the inequality [tex]25x+200y\geq 1000[/tex]
Here, x denotes ounces of whole milk and y denotes ounces of cheddar cheese.
To write: three different amounts of milk and cheese that a person could consume to meet the recommendation
Solution:
Take [tex]x=20,y=3[/tex]
[tex]25(20)+200(3)\geq 1000\\500+600\geq 1000\\1100\geq 1000[/tex]
So, [tex]x=20,y=3[/tex] satisfy the inequality [tex]25x+200y\geq 1000[/tex]
Take [tex]x=30,y=4[/tex]
[tex]25(30)+200(4)\geq 1000\\750+800\geq 1000\\1550\geq 1000[/tex]
So, [tex]x=30,y=4[/tex] satisfy the inequality [tex]25x+200y\geq 1000[/tex]
Take [tex]x=40,y=5[/tex]
[tex]25(40)+200(5)\geq 1000\\1000+1000\geq 1000\\2000\geq 1000[/tex]
So, [tex]x=40,y=5[/tex] satisfy the inequality [tex]25x+200y\geq 1000[/tex]
Therefore,
three different amounts of milk and cheese that a person could consume to meet the recommendation are as follows:
20 ounces of milk and 3 ounces of cheddar cheese
30 ounces of milk and 4 ounces of cheddar cheese
40 ounces of milk and 5 ounces of cheddar cheese

Josh took his girlfriend out to dinner for her birthday. Dinner was $74.96. Tax on the meal was 7.5% of the price of the meal. They left a tip that was 18% of the meal and tax. What is the total cost of the meal?
Answer:
$97.07
Step-by-step explanation:
7.5% of 74.96 is 5.62
18% of 74.96 is 13.49
74.96+5.62+13.49=97.07
Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,029 feet. The lowest feature on Earth is the Challenger Deep with an elevation -35,797 feet. What elevation does sea level represent in this scenario? Which feature is farther from sea level?
Answer:
[tex]Sea\ Level = 0\ ft[/tex]
The farthest point is the Challenger Deep
Step-by-step explanation:
Given
[tex]Highest = +29029ft[/tex]
[tex]Least = -35,797ft[/tex]
Solving (a): The sea level
Both elevations had signs in front of them.
The sea level is the point at the neutral level, neither positive nor negative.
Hence:
[tex]Sea\ Level = 0\ ft[/tex]
Solving (b): Farthest Point.
The farthest point is the one with the highest magnitude.
Comparing
[tex]Highest = +29029ft[/tex] to [tex]Least = -35,797ft[/tex]
-35,797 ft has the highest magnitude.
Hence:
The farthest point is the Challenger Deep

To manage a rental property, a property manager charges $65 per month plus 6% of the rent.
If Jack pays the property manager $164 each month, what is the monthly rent on his property?
Given parameters:
Charge per month = $65
Percentage on rent= 6%
Amount paid by Jack per month = $164
Unknown:
Monthly rent on his property = ?
Solution:
Monthly rent on his property can be found by;
Amount paid by Jack per month = Charge per month + 6% of monthly rent
Let the monthly rent = x ;
So;
164 = 65 + [tex]\frac{6}{100} x[/tex] x
164 - 65 = [tex]\frac{6x}{100}[/tex]
99 = [tex]\frac{6x}{100}[/tex]
6x = 9900
x = 1650
Monthly rent on his property is $1650

brainlllyy i need an answer what’s the slope of this line
Answer:
4/5
Step-by-step explanation:
The slope of the line is 4/5.
To find out the slope of a line, you must remember rise over run. Using that, you count up from whenever the line meets an actual whole number, which in this case it is -2, and then count up 4, and then you start counting right to meet the point (3, 4). The number of spaces you go to the right is 5, making the slope 4/5.
Hope this isn't too confusing and that it helps :)

4 (3q-2) = 4q + 2q
Show your work
Answer:
8/6 or 1 1/3
Step-by-step explanation:
Step 1:
4 ( 3q - 2 ) = 4q + 2q Equation
Step 2:
12q - 8 = 4q + 2q Multiply
Step 3:
12q - 8 = 6q Combine Like Terms
Step 4:
12q = 6q + 8 Add 8 on both sides
Step 5:
6q = 8 Subtract 6q on both sides
Step 6:
q = 8 ÷ 6 Divide
Answer:
q = 8/6 or 1 1/3
Hope This Helps :)
Answer:
Hi there! The answer is q=4/3.
Step-by-step explanation:
First—Distrubute the 4 on each side of 3q-2. You should get 12q-8 on the left side of the equation.
Second— Combine like terms. You should see the 4q+2q obviously. Since they have the same letters, they should be combined Into 6q.
as a result you should have 12q-8 on the left side and 6q on the right side.
Switch 6q’s place with -8. But make sure you change the signs of negative and positives as you switch.
Now you should have 12q-6q=8.
Combine like terms again which will be 12q-6q Which will become 6q.
Now you should have 6q=8. divide 6 to both sides of the equation.
Since 6/6 = 1, there should be no coefficients stuck on the q.
when 8 is divided by 6, you should get 8/6.
WAIT YOU ARE NOT FINISHED YET!! YOU HAVE ONE MORE STEP AND YOU WILL HAVE ANSWER.
simplify 8/6 top and bottom divided by 2 each, then you should have 4/3.

y = 9
y = 4x
y = 3x + 1
ILL MAKE MOST BRAINLIEST!!!
Given:
There exist a proportional relationship between x and y.
To find:
The equation which represents a proportional relationship between x and y.
Solution:
If there exist a proportional relationship between x and y, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
We know that, proportional relationship passes through the origin because (0,0) satisfy [tex]y=kx[/tex].
For x=0, check which equation has y=0.
In option A, [tex]y=-3(0)-2=-2[/tex].
In option B, [tex]y=9[/tex].
In option C, [tex]y=4(0)=0[/tex].
In option D, [tex]y=3(0)+1=1[/tex]
Only in option C, we have a equation of the form [tex]y=kx[/tex] with 4 as constant of proportionality and it passes through (0,0).
Therefore, the correct option is C.
