Answer:
Parts of oil in 42 cups of marinade = 21 cups
Parts of soy sauce in 42 cups of marinade = 14 cups
Parts of orange juice in 42 cups of marinade = 7 cups
Step-by-step explanation:
Given that:
Parts of oil = 3
Parts of soy sauce = 2
Part of orange juice = 1
Total cups of marinade = 42
To find:
How much of each ingredient should be there ?
Solution:
This problem can be solved by taking the ratio of ingredients into account.
The ratio is:
Oil : Soy Sauce : Orange Juice = 3 : 2 : 1
So, we can let the parts of oil = [tex]3x[/tex]
Parts of soy sauce = [tex]2x[/tex]
Parts of orange juice = [tex]x[/tex]
As per the question statement:
[tex]3x+2x+x=42\\\Rightarrow 6x=42\\\Rightarrow x =7[/tex]
So, parts of oil in 42 cups of marinade = 3 [tex]\times[/tex] 7 = 21 cups
Parts of soy sauce in 42 cups of marinade = 2 [tex]\times[/tex] 7 = 14 cups
Parts of orange juice in 42 cups of marinade = 7 cups
You randomly draw A marble from a bag, record it’s color, and then replace it. You draw a blue marble 11 out of 50 times. What is the experimental probability that the next marble will be blue?
Answer:
since you recorded the first marble then replaced it, you drew 10 blue marbles, so therefore we can predict the next marble you drew, was blue.

Tiffany Is Filling Her Daughter's Pool With Water From A Hose. She Can Fill The Pool At A Rate Of 1/10 Gallons/Seconds. How Fast Can She Fill Up A 20 Gallon Pool
Answer:
200 seconds
Step-by-step explanation:
Given rate :
Filling rate = 1/10 gallons per second
How fast can a 20 gallon pool be filled ;
Time = size of pool / filling rate
Time = 20 gallons ÷ 1/10 gallon / second
Time = 20 * 10 / 1
Time = 200 seconds
what is the mass of an object that weighs 7 kg and 50 N?
Answer:
7kg
Step-by-step explanation:
mass: amount of matter in a substance,
SI Unit: kg
It has nothing to do with N (weight) in this case so take the kg value as the mass
Answer:
0.71 kg
Step-by-step explanation:
a common equation in physics is w = mg
we can rearrange this to m = w/g
g is the acceleration of gravity: 9.81 m/s^2
w is the weight of the given equation of the object: 7 kg
so m = 7 kg ÷ 9.81 m/s^2
this gives us: m = 0.71 kg

Inspecting a 7th-degree polynomial of 'n' by taking its derivatives
From the given conditions,
2n7+n6+2n4+2n3+2n2
=(n+1)7+(n+1)5+(n+1)4+2(n+1)3+(n+1)2+2(n+1)+1.

n7-6n6-22n5-39n4-49n3-42n2-26n-9=0 .....[1].
Let A(n)=n7-6n6-22n5-39n4-49n3-42n2-26n-9.
For n>2, A(n)<n7-6n6-22n5.
Since A(n)=0,
0<n7-6n6-22n5.
0<n5(n-3+√31)(n-3-√31).
Since n>2, n>3+√31, which means n≥9 .....[2].
Now, to differentiate A(n),
A'(n)=7n6-36n5-110n4-156n3-147n2-84n-26.
A''(n)=42n5-180n4-440n3-468n2-294n-84.
A'''(n)=210n4-720n3-1320n2-936n-294.
A(4)(n)=840n3-2160n2-2640n-936.
A(5)(n)
=2520n2-4320n-2640
=2520{(n-6/7)2-262/147}.
If A(5)(n)=0, n=6/7±√(262/147).
Therefore, A(5)(n)>0 for n≥3.
Although n≥9 according to [2], I try inspecting A(n) for n≥10.
When n≥10, A(4)(n) increases monotonously.
A(4)(10)=840000-216000-26400-936>0.
Therefore, A(4)(n)>0 for n≥10.
And when n≥10, A'''(n) increases monotonously.
A'''(10)=2100000-720000-132000-9360-294>0.
Therefore, A'''(n)>0 for n≥10.
And when n≥10, A''(n) increases monotonously.
A''(10)=4200000-1800000-440000-46800-2940-84>0.
Therefore, A''(n)>0 for n≥10.
And when n≥10, A'(n) increases monotonously.
A'(10)
=7000000-3600000-1100000-156000-14700-840-26>0.
Therefore, A'(n)>0 for n≥10.
And when n≥10, A(n) increases monotonously.
A(10)
=107-6000000-2200000-390000-49000-4200-260-9>0.
Therefore, A(n)>0 for n≥10 .....[3].
From [2] and [3], A(n)=0 only when 9≤n<10.
In consequence, n=9.

sorry to bother but it's mr. Mac purchase the kitchen table that was on sale for 20% off the original price of the table was 700 what would be the total amount he saved?
Step-by-step explanation:
Given parameters:
Amount of discount on goods= 20%
Original price of the good = 700
Unknown:
Total amount he saved = ?
Solution:
The total amount he saved will be the value of the discount charged on the original price.
Amount of discount = Percentage discount x original price of goods
Amount of discount = [tex]\frac{20}{100}[/tex] x 700
Amount of discount = 140
The amount saved is 140
A jar has 32 marbles. Some are blue and the rest are green. There are three times as many green marbles as blue. How many green marbles are in the jar
Answer: 24
Step-by-step explanation:
Number of marbles in jar = 32
Let blue marbles be represented by b.
Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b
We then add them together. This will be:
3b + b = 32
4b = 32
b = 32/4
b = 8
There are 8 blue marbles
Since green is 3× blue. Therefore,
Green = 8 × 3 = 24 marbles

Answer:
21.068 rounded to the nearest 10th is 21.1
Step-by-step explanation:
To round a number to the nearest tenth , look at the next place value to the right . If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
An electrician charges $35 per hour, h, plus a $20 fee for driving to your house. Which equation represents to total cost, T, for the electrician to do a job?
Answer:
T= 20 + 35h
Step-by-step explanation:
Giving the following information:
An electrician charges $35 per hour, h, plus a $20 fee for driving to your house.
The $20 fee is a fixed cost. It will remain constant.
The $35 fee acts as a variable cost. It varies with the number of hours required to do the job.
To calculate the total cost (T), we need to use the following formula:
T= 20 + 35h
h= number of hours.

Which is the best estimate of the distance between the point (-25, 10) and the origin?
O 8 units
w
O 15 units
O 23 units
O 27 units
The best estimate of distance between the point and the origin is 15 units. this is your answer.
The distance between the point (-25, 10) and the origin is 27units
Distance between two pointsThe formula for calculating the distance between two points is expressed as:
D = √x² + y² (since the other coordinate is an origin)
Given the coordinate points (-25, 10) and (0, 0)
Substitute
D = √(-25)² + 10²
D = √625 + 100
D = √725
D = 27unts
Hence the distance between the point (-25, 10) and the origin is 27units

Ok but fr help.. Assuming only the lengths of the sides of a triangle are given, how can you determine if the triangle has a right angle?
Answer:
If you take the 2 smallest sides and put it in the pythagreon theorem to get the other side length.
Step-by-step explanation:
So if you have a triangle with side lengths, 3, 4, and 5, you can use the exact equation below.
[tex] {3}^{2} + {4}^{2} = {5}^{2} [/tex]
Because this is true, then the triangle does have a right angle.
P(-,3) , Q(7,-3) and R (4,1) are three points. show that PQ=2QR using distance formula. (please show the steps too :)
Answer:
PQ is 10.
QR is 5.
Hence, PQ=2QR
Step-by-step explanation:
We have the three points P(-1, 3); Q(7, -3); and R(4, 1).
And we want to show that PQ=2QR.
In other words, we want to show that PQ/QR=2.
So, let's find PQ and QR. We will need to use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
To find PQ:
P is (-1, 3) and Q is (7, -3).
So, we will let P(-1, 3) be (x₁, y₁) and Q(7, -3) be (x₂, y₂).
Substitute the values into the distance formula. This yields:
[tex]d=\sqrt{(7-(-1))^2+(-3-3)^2[/tex]
Evaluate:
[tex]d=\sqrt{(8)^2+(-6)^2[/tex]
Evaluate:
[tex]d=\sqrt{64+36}=\sqrt{100}=10[/tex]
So, the distance of PQ is 10.
And to find QR:
Q is (7, -3) and R is (4, 1).
Again, we will let Q(7, -3) be (x₁, y₁) and R(4, 1) be (x₂, y₂).
Substitute appropriately. So:
[tex]d=\sqrt{(4-7)^2+(1-(-3))^2[/tex]
Evaluate:
[tex]d=\sqrt{(-3)^2+(4)^2[/tex]
Evaluate:
[tex]d=\sqrt{9+16}=\sqrt{25}=5[/tex]
So, the distance of QR is 5.
Therefore, it follows that:
[tex]\displaystyle PQ=2QR\Rightarrow \frac{PQ}{QR}=2\Rightarrow\frac{10}{5}\stackrel{\checmark}{=}2[/tex]
And we have shown that PQ=2QR.
310= -6.2f
I’m just struggling on this question;—;
Answer:
Step-by-step explanation:
sup. so what you're going to do is divide -6.2 on both sides to get f by itself
310/-6.2= -6.2f/-6.2
f=-50
Answer:
-50.
Step-by-step explanation:
310 = -6.2f
To solve for f we divide both sides of the equation by -6.2
310 / -6.2 = -6.2f / -6.2
f = -310/-6.2 = -50.

A group of 5 friends decide to set up a lemonade stand. They sell 48 cups of lemonade for $1.35 each. If they split the amount of money they made evenly, how much does each friend take home?
Answer:
Step-by-step explanation:
There are a couple of ways you could do this. The first and most obvious way is just to find out what the total amount is and divide by 5
48 cups * $1.35 / cup = $64.80 total
Now divide by 5
$64.80 / 5 = 12.96 for each person.
The other way to do it is just to divide 1.35 by 5 = 0.27
Now multiply by 48 to get each person's share.
0.27 * 48 = 12.96
Take your pick. The answer is the same either way.
