What is: Q=1/2P+15, solve for P?
Answer:
2 ( Q - 15 ) = P
Step-by-step explanation:
[tex]Q =\frac{1P}{2} + 15[/tex]
First, take 15 to the left side.
[tex]Q -15=\frac{1P}{2}[/tex]
Multiply both sides by 2.
2 ( Q - 15 ) = 1P
Divide both sides by 1.
2 ( Q - 15 ) = P

Brian irons 2/9 of a shirt in 3 3/5 minutes. How long will it take him to iron one shirt? At this rate, how long will it take to iron 5 shirts?
Brian takes 16.2 minutes to iron one shirt and 81 minutes to iron five shirts at the rate of ironing 2/9 of a shirt in 3 3/5 minutes.
Brian irons 2/9 of a shirt in 3 3/5 minutes. To determine how long it takes to iron one full shirt, we can set up a proportion. Since 2/9 of a shirt takes 3 3/5 minutes, we can find the time for 1 shirt by multiplying 3 3/5 by 9/2.
First, we convert 3 3/5 to an improper fraction: (3 * 5) + 3 = 18/5. Now, multiply this by 9/2:
(18/5) * (9/2) = 81/5 = 16.2 minutes. Therefore, it takes 16.2 minutes to iron one shirt.
To find the time for 5 shirts, since the rate of ironing is constant, we multiply the time for one shirt by 5:
16.2 minutes * 5 = 81 minutes.
Brian will take 16.2 minutes per shirt, and 81 minutes for 5 shirts, at the given rate.

If country a has 163,950 million more computers than country b and the total number of computers for both countries is 314,250 million, find the number of computers for each country
Answer:
Country A has 239100 million computers and country B has 75150 computers.
Step-by-step explanation:
Let country A has number of computers = x
and the number of computers in country B = y
By the statement " Country A has 163950 million more computers than country B"
x = y + 163950 ------(1)
Another statement states " Total number of computers in both the countries is 314250 million"
x + y = 314250 --------(2)
Now we place the value of x from equation (1) to equation (2)
y + y + 163950 = 314250
2y = 314250 - 163950
2y = 150300
y = [tex]\frac{150300}{2}[/tex]
= 75150
From equation 1
x = 75150 + 163950
= 239100
Therefore, country A has 239100 million computers and country B has 75150 computers.

Marshall bought some pet supplies for $15. The sales tax was 6%. He wrote the expression 1.06(15) to find his total cost.
Which equivalent expression could he also use to find the total cost?
A (1+0.06)15
B 1+0.06(15)
C15+0.6(15)
D15 + 0.06
Answer:
A is correct
Step-by-step explanation:
Marshall bought some pet supplies for $15
The sales tax was 6%
Expression: 1.06(15)
Cost of pet = $15
Sale tax = 6% of 15
= 0.06×15
Total cost after sale tax = 15 + 0.06×15
Take out 15 common = (1+0.06)15
The given expression is equivalent to (1+0.06)15
1.06(15) = (1+0.06)15
Using (1+0.06)15 to find total cost.

The length of a rectangle is 9 inches more than twice it's with if the perimeter of the rectangle is 90 inches find its length and width
perimeter = 2L + 2W
L = 2w+9
90 = 2(2w+9) + 2W
90 = 4W+18 +2W
90 = 6W +18
72 = 6w
w = 72/6 = 12
l = 2*12+9 = 33
2x12 = 24, 2x33 = 66, 66+24 = 90
Length = 33 inches
Width = 12 inches
A chicken soup recipe calls for 9 cups of chicken stock. How much is this in quarts? Write your answer as a whole number or a mixed number in simplest form. Include the correct unit in your answer.
There are 2.25 quarts in 9 cups of chicken stock.
Here's how we can convert cups to quarts:
Since "quarts" are commonly used as whole numbers or mixed numbers, we don't usually express them in decimals.
Conversion factor: Remember that there are 4 cups in 1 quart. This is the conversion factor we'll use.
Calculation: To find the equivalent amount in quarts, we can multiply the number of cups by the conversion factor:
9 cups * (1 quart / 4 cups) = 2.25 quarts
Therefore, 9 cups of chicken stock is equivalent to 2.25 quarts.
Final answer:
To convert 9 cups to quarts, we can use the conversion factor 4 cups = 1 quart. Therefore, 9 cups of chicken stock is equal to 2 1/4 quarts.
Explanation:
To convert cups to quarts, we can use the conversion factor 4 cups = 1 quart.
Given that the recipe calls for 9 cups of chicken stock, we need to determine how many quarts this is.
Using the conversion factor, we can set up the following proportion: 4 cups / 1 quart = 9 cups / x quarts.
Cross-multiplying, we get 4 * x = 1 * 9, which simplifies to x = 9/4 or 2 1/4 quarts.
Therefore, 9 cups of chicken stock is equal to 2 1/4 quarts.

What is y=-9/2x-11 in standard form?
The standard form of the equation y = - 9/2x - 11 is 9x + 2y = - 22.
Given that,
The equation of a line is,
y = - 9/2x - 11
Now we can change the equation into standard form as,
y = - 9/2x - 11
Multiply both sides by 2;
2y = - 9x - 22
Add 9x on both sides,
2y + 9x = - 22
Arrange the equation,
9x + 2y = - 22
Therefore, the standard form is 9x + 2y = -22.

Sweet T has 2 orange picks for every 5 green. If there are 21 picks in all, how many picks are orange?
Answer:
The number of picks which are orange is:
6
Step-by-step explanation:
Sweet T has 2 orange picks for every 5 green.
i.e. if orange picks=2x then green picks=5x
There are 21 picks in all
i.e. 2x+5x=21
⇒ 7x=21
Dividing both sides by 7
⇒ x=3
So, number of orange picks=2×3=6
The number of picks which are orange is:
6

A house has increased in value by
29%
since it was purchased. If the current value is
$387,000
, what was the value when it was purchased?
Final answer:
The original value of the house before the 29% increase was approximately $300,000, calculated by dividing the current value of $387,000 by the total percentage value of 129%.
Explanation:
The student's question revolves around the concept of percentage increase in Mathematics. To find the original value of the house before the increase, we need to consider the current value as 129% of the original value (since there was a 29% increase). Let's denote the original value as P.
So, we can set up the equation: 1.29 * P = $387,000. To solve for P, we divide both sides by 1.29: P = $387,000 / 1.29. Upon performing this division, we find that P, or the original purchase price of the house was approximately $300,000.
Final answer:
To find the value when the house was purchased, we set up an equation using the given information and solved for the original value. The value of the house when it was purchased was approximately $300,775.19.
Explanation:
To find the value of the house when it was purchased, we need to determine the original value before the 29% increase.
Let's assume the original value is x. The current value is $387,000, which is 29% higher than x.
We can express this as an equation: x + 0.29x = $387,000.
Combining like terms, we get 1.29x = $387,000.
Dividing both sides by 1.29, we find that x = $300,775.19.
Therefore, the value of the house when it was purchased was approximately $300,775.19.

How many liters of milk are in 334 gal (1 gal = 4 qt)? enter your answer in scientific notation?
1.2643275×10³ litres of milk are in 334 gals.
We need to find out how many litres of milk are in 334 gals (1 gal = 4 qt).
What is scientific notation?The scientific notation helps us to represent the numbers that are very huge or very tiny in a form of multiplication of single-digit numbers and 10 raised to the power of the respective exponent. The exponent is positive if the number is very large and it is negative if the number is very small.
We know that, 1 gallon=3.785411784 litre
Now, 334 gallon=334×3.785411784
=1,264.3275 litres
=1.2643275×10³
Therefore, 1.2643275×10³ litres of milk are in 334 gals.

What is the recursive formula for the geometric sequence with this explicit formula?
Final answer:
To write a recursive formula for a geometric sequence, you need to know the first term and the common ratio. The recursive formula is expressed as each term being a multiple of its preceding term.
Explanation:
The question asks us to find a recursive formula for a geometric sequence when its explicit formula is already known. A recursive formula for a geometric sequence defines each term of the sequence as a multiple of the previous term, typically expressed as an = r × an-1, where r is the common ratio and an is the nth term. The first term, often denoted by a1, must be provided to start the sequence. To obtain a recursive formula, you need to know the first term and the common ratio. The explicit formula normally has the form an = a1 × rn-1. Using this explicit formula, you would need to solve for a1 and r to write the recursive formula.
