How much punch did Susan make altogether? 3 cups seltzer water 1 gallon apple juice 4 pints lemonade
Answer:
Susan makes [tex]13\frac{1}{2}[/tex] pints of punch.
Step-by-step explanation:
Consider the provided information.
We know that:
2 cups (c) = 1 pint (pt)
4 cups (c) = 1 quart (qt)
16 cups (c) = 1 gallon (gal)
So 3 cups = [tex]1\frac{1}{2}[/tex] pint
1 gallon = 16 cups = 8 pint
The three mixed together would make [tex]1\frac{1}{2}+8+4=13\frac{1}{2}[/tex] pints of punch.
Hence, Susan makes [tex]13\frac{1}{2}[/tex] pints of punch.

Solve for x. √10x+50=x+5
x = 5 or x = 10
x = 0 or x = 5
x = 0 or x=−5
x = 5 or x=−5
Answer:
x = 5 or x = -5
Step-by-step explanation:
I took the k12 quiz
The solutions are x = 5 and x = -5 for the given equation √10x+50=x+5.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To solve for x in the equation √(10x+50) = x+5, we can first isolate the radical term by squaring both sides:
(√(10x+50))²= (x+5)²
Simplifying the left side gives:
10x+50 = x² + 10x + 25
Combining like terms and moving all terms to one side, we get:
x² - 25 = 0
This is a quadratic equation that can be factored as:
(x-5)(x+5) = 0
Therefore, the solutions are x = 5 and x = -5 for the given equation √10x+50=x+5.

In this number tree, the integers greater than or equal to 0 are written out in increasing order, with the top row containing one integer and every row after containing twice as many integers as the row above it. If row 1 contains the integer 0, what is the fifth number in row 10?
Answer:
The fifth integer in row 10 using the number tree pattern is 515.
Step-by-step explanation:
The attached picture is instrumental to understanding the solution to this. There are different methods to approach this problem. But we will use observations to solve the problem.
Looking at the tree diagram, we see that the first row has 1 integer, the second has 2, the third has 4 and the fourth has 8. From here, we can see that a row has 2^n numbers where n = 0, 1, 2, 3, 4, . . .
Row 1 = 2^0 = 1 number
Row 2 = 2^1 = 2 numbers
Row 3 = 2^2 = 4 numbers
Row 4 = 2^3 = 8 numbers. And so on.
Also we notice that the last number in row 4 is 14. This can be gotten by adding the total number of numbers from row 1 to row 4 which is
1 + 2 + 4 + 8 = 15 but the first number on the chart is 0 which means we have to take out the first integer to get the last integer on row 4. Doing this, we have 14.
Since our aim is to know the fifth number in row 10, then we need to know the last number in row 9 then count from the first number in row 10 to the fifth. Using 2^n to get the number of numbers in each row like we've done above we can add the number of numbers to know the total numbers we have from row 1 to row 9 as follows:
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 = 511
As we've said previously, 0 is the first integer in the tree and should be removed to know the last number in row 9. This would be 510.
If 510 is the last number in row 9 is 510, then the first number in row 10 would be 511. Counting to the fifth number we get to 515. Thus the fifth number in row 10 using the number tree pattern is 515.
On Friday, an art museum sold 720 adult tickets. The number of adult ticket sold was 9 times the number of children's ticket sold. On Saturday, the museum sold 6 times as many children's ticket as on Friday How many children ticket sold on saturday
Answer: 480 children's tickets
Step-by-step explanation:
On the Friday, 720 adult tickets were sold.
This number was 9 times the number of children's tickets sold. Number of adult tickets sold was therefore:
= 720/9
= 80 children's tickets.
On the Saturday, 6 times the above amount was sold:
= 6 * 80
= 480 children's tickets
You are on a treasure-diving ship that is hunting for gold and silver coins. You reel in a wire basket that contains gold and silver coins, among other things. The basket holds no more than 50 pounds of material. Each gold coin weighs about 0.5 ounce, and each silver coin weighs about 0.25 ounce. You want to know the different numbers of each type of coin that could be in the basket.
Answer:
Inequality equation:
0.03125x + 0.015625y ≤ 50 pounds
Step-by-step explanation:
We convert the ounces to pounds
1 ounce = 0.0625 pound
For the gold coin = 0.5 ounce
1 ounce = 0.0625 pounds
0.5 ounce = x
x = 0.5 × 0.00625 pounds
x = 0.03125 pounds
For the Silver coin = 0.25 ounce
1 ounce = 0.0625 pounds
0.25 ounce = x
x = 0.25 × 0.00625 pounds
x = 0.015625 pounds
The basket holds no more than 50 pounds of material.
Let the number of gold coins = x
The number of silver coins = y
Hence: our inequality equation:
0.03125x + 0.015625y ≤ 50 pounds

Point E on the diagonal of the rectangle ABCD, AE:EC=3:1, and AB:BC=5:4. Find the ratio of DE to BE
Answer:
3.88 : 3.25 ≈ 13 : 11
Step-by-step explanation:
I don't know what are you in, geometry or algebra? I'll post my way of solution. It may need some calculator calculation that I can't give detail of steps here. I just like to explore something, wish it help.
suppose D is the origin, DA = 4 and AB = 5
A (0,4) B(5,4) C(5,0) D(0,0)
AE/AC = 3/4 (i.e. AE/EC = 3/1)
parallel of EF with DC and EG with BC
CF/BC = CE/AC = 1/4
CF = BC x 1/4 = 4 x 1/4 = 1
DG/DC = AE/AC = 3/4
DG = DC x 1/4 = 5 x 3/4 = 15/4
coordinator of E (3.75 , 1)
length of DE = √3.75² + 1² = 3.88
length of BE = √1.25² + 3² = 3.25
DE : BE = 3.88 : 3.25 ≈ 13: 11 (3.88/13 ≈ 0.29, 3.25/11 ≈ 0.29)
The nth term of a quadratic sequence is an² + bn where a and b are integers. The second term of the sequence is 8, and the fifth term is 65. What is the value of the tenth term in the sequence?
Step-by-step explanation:
When n = 2,
(2)²a + (2)b = 8.
=> 4a + 2b = 8.
When n = 5,
(5)²a + (5)b = 65.
=> 25a + 5b = 65.
4a + 2b = 8. => 10a + 5b = 20
25a + 5b = 65
- (10a + 5b = 20)
=> 15a = 45, a = 3.
Therefore 4(3) + 2b = 8, 2b = -4, b = -2.
We have a = 3 and b = -2.
Hence when n = 10,
an² + bn
= (10)²(3) + (10)(-2)
= 300 - 20
= 280.
The 10th term of the sequence is 280.
Answer:
The 10th term of the sequence is 280
Step-by-step explanation:
When n = 2,
(2)²a + (2)b = 8.
=> 4a + 2b = 8.
When n = 5,
(5)²a + (5)b = 65.
=> 25a + 5b = 65.
4a + 2b = 8. => 10a + 5b = 20
25a + 5b = 65
- (10a + 5b = 20)
=> 15a = 45, a = 3.
Therefore 4(3) + 2b = 8, 2b = -4, b = -2.
We have a = 3 and b = -2.
Hence when n = 10,
an² + bn
= (10)²(3) + (10)(-2)
= 300 - 20
= 280.

An angle measures 8.2° more than the measure of its complementary angle. What is the
measure of each angle?
9514 1404 393
Answer:
49.1°, 40.9°
Step-by-step explanation:
Let x represent the smaller angle. Then the larger is x+8.2 and the total of the two angles is ...
x + (x +8.2) = 90
2x +8.2 = 90 . . . . . collect terms
x + 4.1 = 45 . . . . . . .divide by 2
x = 40.9
x +8.2 = 49.1
The two angles are 49.1° and 40.9°.
Sara sold 461 tickets for a school play. Student tickets cost $3 and adult tickets cost $4. Sara’s sales totaled $1624.How many adult tickets and how many student tickets did Sara sell?
Answer:
220 student and 241 adults
Step-by-step explanation:
x+y=461
3x+4y=1624
y=-x+461-----> 3x+4(-x+461)=1624
-x+1844=1624
+x -1624
x=220
3(220)+4y=1624
660+4y=1624
4y=964
y=241
There are 241 adult tickets and 220 student tickets did Sara sell.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Sara sold 461 tickets for a school play.
And, Student tickets cost $3 and adult tickets cost $4. Sara’s sales totaled $1624.
Let number of adult tickets = x
And, Number of student tickets = y
Hence, We get;
⇒ x + y = 461 .. (i)
And, 4x + 3y = 1624 .. (i)
Multiply by 3 in (i);
⇒ 3x + 3y = 1383 .. (iii)
Subtract form (ii);
⇒ x = 241
And, From (i);
⇒ x + y = 461
⇒ 241 + y = 461
⇒ y = 461 - 241
⇒ y = 220
Thus, There are 241 adult tickets and 220 student tickets did Sara sell.
