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
How would you "remove the discontinuity" of f ? In other words, how would you define f(5) in order to make f continuous at 5? f(x) = x2 − 3x − 10 x − 5
Divide 5 on each side. Then that would be the answer,f=-8
How do you know when a function is continuous?Saying a characteristic f is continuous whilst x=c is the same as announcing that the characteristic's two-side restrict at x=c exists and is identical to f(c).
How many are continuous variables?Continuous variables are numeric variables that have a limitless quantity of values among any two values. A non-stop variable may be numeric or date/time. For example, the length of a part of the date and time a payment is acquired.

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.

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.
an appliance store sells a washer dryer combination for $1500 if the washer costs $200 more than the dryer find the cost of each appliance.
To find the cost of the washer and the dryer when the total cost is known along with the difference in their costs, we used a simple algebraic method of solving equations to determine that the dryer costs $650 and the washer costs $850.
Explanation:The question involves solving a system of linear equations to find the cost of two items whose total and difference in cost are known. To find the cost of each appliance, let's denote the cost of the dryer as x dollars. According to the problem, the washer costs $200 more than the dryer, so the washer's cost would be x + $200. The total cost of both appliances is $1500.
We can set up the following system of equations:
x + (x + 200) = 1500Solving the equations, we combine like terms:
2x + 200 = 15002x = 1300x = 650Now we know the dryer costs $650 and the washer costs $650 + $200 = $850.

The sum of two consecutive even integers is 218. What are the integers
The required two consecutive even integers that add up to 218 are 108 and 110.
What are integers?Integers are numbers that can be written without a fractional or decimal component, such as -3, -2, -1, 0, 1, 2, 3, and so on. They include the positive whole numbers (1, 2, 3, etc.), the negative whole numbers (-1, -2, -3, etc.), and zero.
To find the two consecutive even integers that add up to 218, we can use algebra.
Let's represent the first integer "x".
Since it is even, we know that it can be divided by 2 with no remainder.
Since it is also consecutive to the second integer, we can say that the second integer is "x + 2".
We can set up the equation:
x + (x + 2) = 218
Simplifying, we get:
2x + 2 = 218
2x = 216
x = 108
So the two consecutive even integers that add up to 218 are 108 and 110.

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.

Step-by-step explanation:
current rules for telephone area codes allow the use of digits 2-9 for the first digit and 0-9 for the second and third digits. how many different area codes are possible with this rules? That same rule applies to the exchange number. which are the three digits immediately preceding the last four digits of a phone number. Given both of those rules, how many 10- digit phone numbers are possible? given that rules apply to the United States and Canada and a few islands, are there enough possible phone numbers? (assume that the combined population is about 400,000,000.
Final answer:
There are 800 possible area codes and exchange numbers each, following the given digit restrictions. The total number of unique 10-digit phone numbers given these rules is 6,400,000,000, which is sufficient considering a population of about 400,000,000.
Explanation:
The question addresses how many different area codes and phone numbers are possible given certain digit restrictions for both the United States and Canada. For the area code, the first digit can be any from 2 to 9, which gives us 8 possibilities, and the second and third digits can be any from 0 to 9, which provides 10 possibilities each. Therefore, the number of different area codes is 8 × 10 × 10 = 800.
Applying the same rules to the exchange number, which also has three digits, we have another 800 possibilities. Considering there are 10,000 combinations for the last four digits (from 0000 to 9999), we can calculate the total number of unique 10-digit phone numbers by multiplying the possibilities for the area code, exchange number, and the last four digits: 800 × 800 × 10,000 = 6,400,000,000 possible phone numbers.
Since the combined population of the United States, Canada, and a few islands is about 400,000,000, this amount of possible phone numbers is more than sufficient to provide a unique phone number for every individual.
