Answer:
6 packs of sugar cookies and 10 packs of chocolate chip cookies.
Step-by-step explanation:
Let the quantity of sugar cookies be x packs and the quantity of chocolate chip cookies be y packs. Total packs are 16. Therefore: x + y = 16. This implies y = 16 - x (Equation 1).
It is given that a pack of sugar cookies is priced at $2.5 and a pack of chocolate chip cookies is priced at $3.5. It is also given that the student spends a total of $50 on the cookies. Since x packs of sugar cookies and y packs of chocolate chip cookies are to be bought, therefore:
2.5x + 3.5y = 50 (Equation 2).
Put equation 1 in equation 2.
2.5x + 3.5(16 - x) = 50.
2.5x + 56- 3.5x = 50.
-x = -6.
x = 6.
Put x = 6 in equation 1.
y = 16 - 6.
y = 10.
Therefore, Angelina will buy 6 packs of sugar cookies and 10 packs of chocolate chip cookies!!!
A dog is standing on a cliff 20 feet above sea level. A dolphin is swimming 6 feet below sea level. An octopus is moving along the seabed, 30 feet below sea level. What is the elevation of the dog, dolphin and octopus?
Plz help!!!!
Answer:
Dog: 20
Dolphin: -6
Octopus: -30
Step-by-step explanation:
The dog is at 20 because it is above sea level meaning it is above the zero, meaning it is plus +
The dolphin is at -6 because it is below sea level meaning it is below zero meaning its a negative -
The octopus is at -30 because it is below sea level meaning it is below zero meaning its a negative -
(Any Thing Below Zero is a Negative & Anything Above Zero is a Positive)
The elevation of the dog is 20 feet.
The elevation of the dolphin is -6 feet.
The elevation of the octopus is -30 feet.
Given,
A dog is standing on a cliff 20 feet above sea level.
A dolphin is swimming 6 feet below sea level.
An octopus is moving along the seabed, 30 feet below sea level.
We need to find out what is the elevation of the dog, dolphin, and octopus.
How do we describe elevation?When we measure the distance we always measure it from the sea level.
The distance measured below the sea level is always described as a negative value.
The distance measured above sea level is always described as a positive value.
We have,
A dog is standing on a cliff 20 feet above sea level.
This is above sea level so we can describe it as:
The elevation of the dog is 20 feet.
A dolphin is swimming 6 feet below sea level.
This is below sea level so we can describe it as:
The elevation of the dolphin is -6 feet.
An octopus is moving along the seabed, 30 feet below sea level.
This is below sea level so we can describe it as:
The elevation of the octopus is -30 feet.
Thus,
The elevation of the dog is 20 feet.
The elevation of the dolphin is -6 feet.
The elevation of the octopus is -30 feet.

0.7 dividee by 0.35
Answer:
2
Step-by-step explanation:
We can find this because it's asking how many times 0.35 goes into 0.7.
Here's an easier example without decimals:
10 / 2 = 5
This is asking how many times 2 goes into 10. The second number in the equation is asking how many times it can go into the first number. In this case, 2 goes into 10 five times.
So in this case, 0.35 goes into 0.7 2 times. To make it easier, you can also do 70 / 35, which makes it easier without the decimals.

What is the volume of the box pictured below?
Answer:
The volume of the box is 3/4 cubic meters.
Step-by-step explanation:
We know that volume = length * width * height. We have length, width, and height already, so all we have to do is multiply.
5/6 * 1 1/8 * 4/5. First we convert 1 1/8 from a mixed fraction, to give us 9/8, as 8/8 = 1.
5/6 * 9/8 * 4/5. 5 * 9 = 45, and 6 * 8 = 48. 45/48 reduces to 15/16.
15/16 * 4/5. 15 * 4 = 60, and 16 * 5 = 80. 60/80 reduces to 6/8, which reduces to 3/4.
15. Explain how you can calculate each square
root mentally.
a) 31 x 31
b) 431 X 431
c) 17 squared
d) 432 squared
Final answer:
Mentally calculating square roots for perfect squares like 31 x 31 or 17 squared is identifying the number that was squared, for instance, 31 or 17 respectively. Larger numbers may require a calculator.
Explanation:
The question is asking how to mentally calculate the square roots of certain numbers. For perfect squares, such as 31 x 31 or 17 squared (which is 17 x 17), the process is straightforward because the square root of a perfect square is the number that was squared.
For instance, the square root of 31 x 31 is 31, and the square root of 17 squared is 17. However, for large numbers like 431 x 431 or 432 squared, while they are also perfect squares, mental calculation might be impractical due to their magnitude, and a calculator would typically be used.

With water from one hose, a swimming pool can be filled in 9 hours. A second, larger hose used alone can fill the pool in 2 hours. How long would it take to fill the pool if both hoses were used simultaneously?
1/9 + 1/2 = 1/x
Let x = length of time it will take both hoses to work together
Multiply both sides by 18x.
2x + 9x = 18
10x = 18
x = 18/10
x = 9/5
x = 1.8 hours
In other words, if both hoses work together, the pool can be filled in 1 hour and 48 minutes.

What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have an angle PQR is dilated by a scale factor of 3 using the origin as the centre.
Here the point P is not given, so we are assuming the point P is (6, 2)
After dilated by a scale factor of 3 using the origin as the centre:
P' = (6×3, 2×3)
P' = (18, 6)

SV is an angle bisector of ∠RST. If m∠RSV = (2x + 8)° and m∠RST = (6x − 26)°, find x.
Answer:
x = 21
Step-by-step explanation:
Given that SV is the angle bisector of ∠RST, then
∠RSV = ∠TSV, thus
∠RSV + ∠TSV = ∠RST ← substitute values
2x + 8 + 2x + 8 = 6x - 26, that is
4x + 16 = 6x - 26 ( subtract 6x from both sides )
- 2x + 16 = - 26 ( subtract 16 from both sides )
- 2x = - 42 ( divide both sides by - 2 )
x = 21
- In your opinion, should Cromwell have treated
the rebels so harshly? (Explain with evidence)
Answer:
yes they were rebels
Step-by-step explanation:
respect is earned, if you act a certain way you will be treated like that
Cromwell's harsh treatment of rebels during the English Civil War can be seen as a pragmatic approach to maintain discipline and discourage uprisings, but also as excessively cruel and counterproductive, particularly in the case of his actions in Ireland. It's worth noting that historical judgments depend heavily on the values and perspectives applied to the past.
Explanation:Whether Oliver Cromwell should have treated the rebels so harshly during the English Civil War is a matter of perspective and is heavily debated among historians. Cromwell is known for his decisive, and yes, often harsh measures against those who rebelled against the Parliamentarian cause during the war. From a pragmatic viewpoint, one might argue that his harsh treatment of the rebels was necessary to maintain discipline and to discourage other potential uprisings. This included the crushing of the Levellers in the New Model Army and his later actions in Ireland.
However, there is also a compelling argument that his actions were excessively cruel and counterproductive to his stated goals. Numerous historical accounts indicate that his actions in Ireland, including the infamous massacre at Drogheda, served to perpetuate animosity towards English rule, contributing to centuries of tension and conflict.
The difficulty with questions like these is that they often involve value judgements. History, as a discipline, attempts to understand the past 'as it really was', acknowledging that people of the past operated according to different sets of values and contexts.

Answer: 40$
Step-by-step explanation: before the mowing 20$ if half is on the game before game would be 40
Answer:
He had $ 40 before bought the game.
Step-by-step explanation:
Let x be the original amount ( in dollars ) contained by Ken,
His spending on game = half of his money = [tex]\frac{x}{2}[/tex]
So, the remaining money = [tex]x-\frac{x}{2}[/tex] = [tex]\frac{x}{2}[/tex]
Now, his earning = $ 12,
Thus, final amount he has = remaining amount + earning
[tex]\frac{x}{2}+12[/tex]
According to the question,
[tex]\frac{x}{2}+12=32[/tex]
[tex]\frac{x}{12}=20[/tex]
[tex]\implies x= 40[/tex]
Hence, he had $ 40 before bought the game .

The great factory makes 6,793 toys each day. It makes 257 more toys than the super toy factory. How many toys does the super toy factory make each day?
Final answer:
The super toy factory makes 6,536 toys each day, which is calculated by subtracting the 257 additional toys made by the great factory from its total production of 6,793 toys.
Explanation:
To determine how many toys the super toy factory makes each day, we need to subtract the number of additional toys made by the great factory from its total daily production. The great factory makes 6,793 toys each day and it makes 257 more toys than the super toy factory. So:
Number of toys made by the super toy factory = Number of toys made by the great factory - Extra toys made by the great factory
Number of toys made by the super toy factory = 6,793 - 257
After performing the subtraction:
Number of toys made by the super toy factory = 6,536
Therefore, the super toy factory makes 6,536 toys each day.
