Angelina spend $50 on 16 packages of cookies for her club members. sugar cookies cost $2.50 per package and chocolate chip cookies cost $3.50 per package. how many packages of each cookie does Angelina buy?
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!!!
Linda planned to spend 9 hours practicing piano this week. By Tuesday, she had spent 2 1/2 hours practicing. How much longer does she need to practice to reach her goal?
Answer:
[tex]6\frac{1}{2}[/tex] hours more.
Step-by-step explanation:
We have been given that Linda planned to spend 9 hours practicing piano this week. By Tuesday, she had spent 2 1/2 hours practicing.
To find number of hours Linda needs to practice to reach her goal, we will subtract 2 1/2 from 9 as:
[tex]9-2\frac{1}{2}[/tex]
Convert mixed fraction into improper fraction:
[tex]2\frac{1}{2}\Rightarrow \frac{2\times 2+1}{2}=\frac{4+1}{2}=\frac{5}{2}[/tex]
[tex]9-2\frac{1}{2}\Rightarrow 9-\frac{5}{2}[/tex]
[tex]\frac{9*2}{2}-\frac{5}{2}[/tex]
[tex]\frac{18}{2}-\frac{5}{2}[/tex]
Combine numerators:
[tex]\frac{18-5}{2}[/tex]
[tex]\frac{13}{2}[/tex]
[tex]6\frac{1}{2}[/tex]
Therefore, Linda needs to practice [tex]6\frac{1}{2}[/tex] hours more to reach her goal.
Linda needs to practice for 7 hours and 30 minutes more to reach her 9-hour goal. She's already practiced for 2 1/2 hours, so subtracting this from the total planned practice time of 9 hours gives us the remaining time needed.
Explanation:Linda planned to spend a total of 9 hours practicing piano this week. By Tuesday, she had already spent 2 1/2 hours on her practice. To find out how much more time she needs to practice to reach her goal, we subtract the time she has already practiced from the total planned practice time.
Here's the step-by-step calculation:
Write down the total number of hours planned for practice: 9 hours.
Write down the number of hours already practiced: 2 1/2 hours.
Convert the 1/2 hour into minutes to make the subtraction easier: 2 hours + 30 minutes.
Now subtract the hours and minutes separately: (9 hours - 2 hours) = 7 hours. Then subtract the minutes, but since there are no minutes in 9 hours, it remains the same: 30 minutes.
So, Linda needs to practice for 7 hours and 30 minutes more to reach her 9-hour goal.
which is the quotient (3x^2+8x-3)÷(x+3)?
a) 3x+5, r=1
b) 3x-5
c) 3x+1
d) 3x-1
Answer:
d) 3x - 1
Step-by-step explanation:
Since the divisor is in the form of x - c, use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOSITE terms of what it really is, so do not forget it. Anyway, here is how it is done:
-3| 3 8 -3
↓ -9 3
__________________
3 -1 0 → 3x - 1
You start by placing the c in the top left corner, then list all the coefficients of your dividend [3x² + 8x - 3]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is, tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 3 in your quotient can be a 3x, then -1 follows right behind it.

What is7766 rounded to the nearest thousands
7766 rounded ot the nearest thousands would be 8000, since the hundreds place value, 7, is going to be rounded up to 8000.
Hope this helped!

8000
Step-by-step explanation:
|Thousands||Hundreds||Tens||Ones|

5 or more, raise the score (turn the 7 into an 8 and make the three other numbers 0)
4 or less, let it rest (leave the 7 as a 7 and make the other 3 numbers 0).
The number that we are looking at changing will be bold. The number that determines if we change that number will be underlined.
7766
The 5 or more, raise the score rule applies to 7.
So, we will make the 7 thousand (7000) 8 thousand (8000)
We will make the seven hundred sixty six (766) zero (0).
Our final answer is 8000.

So we start out by plugging in the values for x and y which becomes:
-3 + (-3 x 10)
Then we do PEMDAS which tells us to solve the values inside the parentheses first( P in PEMDAS) which becomes:
-3 + -30
A negative number added to another negative number stays negative, giving us the answer:

A farmer sells an average of 15 3/5 bushels of corn each day. What integer represents the change in bushels of corn in his inventory after 6 days.
Answer:
A farmer sells an average of 15 3/5 bushels of corn each day.
In mixed fraction it is ;
[tex]\frac{78}{5}[/tex]
Let us say he has a total of x bushels.
So, after 6 days, he will sell, [tex]6\times\frac{78}{5}[/tex] bushels of corn.
= [tex]\frac{468}{5}[/tex] bushels of corn.
Hence, his left over inventory will have = [tex]x-\frac{468}{5}[/tex] bushels.

If A = (0,0) and B = (8, 2), what is the length of AB?
Answer:
2√17
Step-by-step explanation:
√((8 - 0)² + (2 - 0)²)
√(64 + 4)
√68
2√17
The length of segment AB, where A = (0,0) and B = (8, 2), is calculated using the distance formula, resulting in a length of AB is √68.
To calculate the length of segment AB where A = (0,0) and B = (8, 2), we can use the distance formula derived from the Pythagorean theorem. The distance formula for two points A(x1, y1) and B(x2, y2) in a coordinate plane is the square root of the sum of the squares of differences between corresponding coordinates:
Distance AB = √[(x2 - x1)² + (y2 - y1)²]
Plugging in the coordinates of points A and B, we get:
Distance AB = √[(8 - 0)² + (2 - 0)²] = √[64 + 4] = √68
Therefore, the length of AB is √68, which is the exact length of the segment AB between points A and B.
How can you write 200,000 using a whole number and a power of 10
Hey!
-----------------------------------
Question Explanation:
In other words you can write 200,00 using a whole number and a power 10 using scientific notation!
In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.
-----------------------------------
Solution:
200,000 / 10 = 20,000
20,000 / 10 = 2,000
2,000 / 10 = 200
200 / 10 = 20
20 / 10 = 2
I divided 200,000 by 10 five times to get a number less than 10.
So, 5 is going to be the exponent.
-----------------------------------
Answer:
2 x 10^5
-----------------------------------
Hope This Helped! Good Luck!
200,000 can be expressed as 2 x 10^5 in scientific notation, which helps to simplify handling of large and small numbers by reducing the number of zeros.
Explanation:To express 200,000 using a whole number and a power of 10, we need to move the decimal place. Start by writing the number as 2 followed by five zeros, or 2,00000. The power of 10 is determined by the number of places we move the decimal. In this case, the decimal is moved 5 places to the left, so we use 10 to the power of 5. Thus, 200,000 can be written as 2 x 105.
This method is known as scientific notation or powers-of-ten notation. It simplifies dealing with very large and small numbers by reducing the number of zeros we have to keep track of. It also makes mathematical operations easier. For instance, when multiplying numbers in this notation, we need to multiply the numbers out front and then add the exponents.

prove that 1÷loga ab + 1÷logb ab=1
Answer:
See below.
Step-by-step explanation:
1 ÷ loga ab + 1 ÷ logb ab
= 1 / (loga ab) + 1 / (loga ab / loga b) { change of log base)
= 1 / (loga ab) + loga b / (loga ab)
= (1 + loga b) / loga ab
= (1 + loga b) / (loga a + loga b) Now loga a = 1 so we have:
