A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 60 kg of a mix
that will sell for $1.40 per kg?
1. The amount of nuts is ____kg and cereal mixture is ____ kg to obtain 60 kg of a mix that will sell for $1.40 per kg.
Answers
Answer:
44kg of cereal, 16kg of nuts
Step-by-step explanation:
Step 1. We work out how much the party mix would cost if all of it was nuts.
$2.50 x 60kg = $150
Step 2. We work out how much we want the party mix to cost if it had the correct ratio of nuts and cereal.
$1.40 x 60kg = $84
Step 3. We work out the difference between the two above numbers.
$150 - $84 =$66
Step 4. We work out the difference between the nut mix and the cereal mix.
$2.50 - $1 = $1.50
Step 5. We divide the answer to step 3 ($66) by the difference between the nut mix and cereal mix.
$66 ÷ $1.50 = 44
Step 6. The answer to step 5 is the mass of the cereal mix. We then minus 44kg from the total mix mass of 60kg to get the mass of the nut mix.
60kg - 44kg = 16kg
Step 7. We double check.
44kg of cereal = $44 16kg of nuts = $40 $44 + $40 = $84
$84 ÷ 60kg = $1.4 per kg
Hope this helped!

Complete the recursive formula of the arithmetic sequence -17, -8, 1, 10,... a(1)= a(n)=a(n-1)+
Answers
To find a(1), simply look at the first term, which is -17. This gives a starting point for the recursive formula.
Then, we want to write the recursive formula as a(n) = a(n - 1) + c, where c is the number you add to a term to get the next term. You can see from the values given that you are adding 9 to each term to get the next one, so the recursive formula would be a(n) = a(n - 1) + 9.
First term of sequence of arithmetic (a₁) is -17 and aₙ is -17 + 9(n-1)
What is arithmetic sequence?
A arithmetic sequence is defined as an arrangement of numbers which is particular order.
The formula to find the general term of an arithmetic sequence is,
aₙ = a₁ + (n-1)d
What is geometric sequence?The geometric sequence defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Given data :
The arithmetic sequence -17, -8, 1, 10,...
First term of sequence of arithmetic (a₁) = -17
The common difference of arithmetic (d) = difference between the two term
The common difference of arithmetic (d) = -8 - (-17)
The common difference of arithmetic (d) = -8 + 17
The common difference of arithmetic (d) = 9
To determine the n term of arithmetic sequence
The nth term of a arithmetic sequence is expressed as :
aₙ = a₁ + (n-1)d
substitute the values of a₁ and d in the formula,
aₙ = -17 + (n-1)9
Let n = 5
a₅ = -17 + (5 - 1)9
a₅ = -17 + (4)9
a₅ = -17 + 45
a₅ = 28

In the circle below, O is the center and mĞ= 128° What is the measure of angle HIG?
Answers
Answer:
26 degrees.
Step-by-step explanation:
From the figure it is clear that HI is the diameter and [tex]acr(GI)=128^{\circ}[/tex]. So,
[tex]\angle GOI=128^{\circ}[/tex]
[tex]\angle GOI+\angle GOH=180^{\circ}[/tex] (linear pair)
[tex]128^{\circ}+\angle GOH=180^{\circ}[/tex]
[tex]\angle GOH=180^{\circ}-128^{\circ}[/tex]
[tex]\angle GOH=52^{\circ}[/tex]
Using central angle theorem of a circle, we get
[tex]\angle HIG=\dfrac{\angle GOH}{2}[/tex]
[tex]\angle HIG=\dfrac{52^{\circ}}{2}[/tex]
[tex]\angle HIG=26^{\circ}[/tex]
Therefore, the measure of angle HIG is 26 degrees.
Which is the graph of y = [x] - 2?
Answers
Explanation:
The notation [tex]\lfloor x \rfloor[/tex] means "floor of x". Whatever decimal value x is, we just ignore the decimal portion and just focus on the integer part. We round down to the nearest whole number. We always round down.
For something like x = 2.5 or x = 2.7, the value of [tex]\lfloor x \rfloor[/tex] will be 2. It doesn't matter that 2.7 is closer to 3 than it is to 2. The interval [tex]2 \le x < 3[/tex] will be entirely on the x axis since we are taking the result of the flooring operation and subtracting off 2. Notice how x = 3 is not included. This is because x = 3 leads to y = 1 instead of y = 0. So we have an open hole at the end of the interval. The same goes for any other piece as well.

Plug the values
[tex] = 2 \times 4 - 10 + 8 \times 4[/tex]

Answer:
30
Step-by-step explanation:
To solve your question we must first replace y with the given number. In this case, the number given is 4 so,
2 (4) - 10 + 8 (4)
We can now solve by multiplying 2 by 4 and 8 by 4
2 * 4 = 8
8 * 4 = 32
8 - 10 + 32 = 30

divide both sides by 40 to get 7/10
HOPE THIS HELPS!!!:)
Answer:
0.7 or 7/10
Step-by-step explanation:
Step 1: Cross-multiply.
2x+1 / 4 = 12 /20
(2x+1)*(20)=(12)*(4)
40x+20=48
Step 2: Subtract 20 from both sides.
40x+20−20=48−20
40x=28
Step 3: Divide both sides by 40.
40x /40 = 28 /40

pi * 3^2 = pi * 9 = 9pi.
This is a semicircle, so the area will be half of the whole circle.
9pi / 2 = 4.5 * pi = 4.5 * 3.14 = 14.13 units^2.

Answers
Answer:
( x + y )² = 32
Step-by-step explanation:
So far, I can tell that your calculations are incorrect. ( x + y )² is indeed x² + 2xy + y², which you can prove right by expanding the expression ( x + y )( x + y ). You simply swapped the positioning in this second step, and decided that the addition of x² + y² is x²y², but that is incorrect. You can't combine the two terms unless you multiply the two.
We should just be left with the expanded expression x² + y² + 2xy. Given that x² + y² = 17, and xy = 7.5, let's substitute and solve for the value of the expression.
17 + 2( 7.5 ) = 17 + 15 = 32,
( x + y )² = 32

Students in Mr. Taylor's physics class conducted an experiment by dropping a basketball from a height of 40 feet and then recording the ball’s height after each bounce. The ball climbed to a height of 20 feet after the first bounce, and 10 feet after the second bounce. If this pattern continues, how many feet high will the ball climb after the third bounce? Input the answer using numbers only.
Answers
Answer:
The answer would be 5 feet
Step-by-step explanation:
The class dropped the ball from 40 feet than after the ball bounced again it went to 20 feet than after the 2nd bounce it went to 10 feet and the pattern so far goes 40, 20, and 10. We need to find the common pattern of these 3 numbers and find the 4th number or [tex]x[/tex] so to find the 4th number you can see that if you divide every number by 10 than you will get 4, 2, and 1 which you can see when divided by 2 every time goes to the next number so 4 divided by 2 is 2 and 2 divided by 2 is 1 so we can assume 1 divided by 2 will be x divided by 10 so 1/2 is 0.5 so x divided by 10 is equal to 0.5 so the equation would be [tex]\frac{x}{10} =0.5[/tex] so we could multiply by 10 on both sides so we would get x = 5 so the final answer would be 5.
