Answer:
5.5lb of strawberries cost $10.78
Step-by-step explanation:
We can use ratios to solve this problem.
lb : $$$
0.5 : 0.98
5 : 9.8
5.5 : 10.78
5.5lb of strawberries cost $10.78
You can also divide 5.5 by 0.5 (pounds) and multiply the quotient by how much a 0.5 pound of strawberries cost.
To find the total cost of 5.5 pounds of strawberries, determine the cost of one pound by doubling the cost for a half-pound. Then multiply the cost of one pound by the quantity of pounds purchased to get the total cost, which is $10.78.
Explanation:The question asks us to calculate the total cost of 5.5 pounds of strawberries when given the price for a half-pound. The first step is to determine the cost of one pound of strawberries by doubling the cost of the half-pound.
If a 1/2 pound of strawberries costs $0.98, then one pound would cost $1.96 (since 0.98 x 2 = 1.96).
Next, to find out how much 5.5 pounds would cost, multiply the cost of one pound by 5.5:
5.5 pounds of strawberries x $1.96 per pound = $10.78.
Therefore, if you bought 5.5 pounds of strawberries, you would have spent $10.78.

When Belinda asked him to what pages his book was opened, he replied that the product of the facing pages was 87,912. To what pages did Theo open his textbook?
Final answer:
To determine the page numbers, the product of two consecutive page numbers (n and n+1) was calculated to match 87,912, leading to the solution that Theo's textbook was opened to pages 296 and 297.
Explanation:
To find out to which pages Theo opened his textbook, when the product of the facing pages was 87,912, we should realize that facing pages in books have consecutive numbers. Therefore, if one page is n, the facing page would be n+1. The product of these two pages is n(n+1)= 87,912. We are solving a quadratic equation here.
Starting with an approximation, square roots of numbers near 87,912 can help identify potential page numbers. The square root of 87,912 is a bit less than 300 (since 300² = 90,000). Therefore, one of the page numbers will be just under 300, and the other just above.
Attempting a few calculations, we notice that 296² = 87,616 and 297² = 88,209. Between these two, 296 × 297 = 87,912, giving us the page numbers Theo's book is open to: 296 and 297.

What are the solutions to the quadratic equation (5y+6)2=24?
Answer:
You chose the right answer
y = [ -6 + 2 root(6)]/5 or y = [-6 - 2 root(6)]/5
Step-by-step explanation:
from (5y + 6)^2 = 24
we can take the square root of both sides
(5y + 6) = + root(24) or (5y + 6) = -root(24)
5y + 6 = 2*root(6) or 5y + 6 = - 2 root(6)
y = [ -6 + 2 root(6)]/5 or y = [-6 - 2 root(6)]/5

A group of 5 families at Baileys Middle School sold magazine subscriptions to raise money for the school. $6.00, $7.00, $4.00, $5.00, $3.00 What was the median amount of money raised?
Answer:
The median amount of money raised is $5.00
Step-by-step explanation:
To find the median amount of money raised, we will follow the steps below:
First, arrange the data giving in ascending order. That is
$6.00, $7.00, $4.00, $5.00, $3.00
We will arrange it in ascending order, hence
$3.00, $4.00, $5.00, $6.00, $7.00
The median is the middle number, we will now proceed to take the middle number.
The middle number is $5.00
Therefore, the median amount of money raised is $5.00
The median amount of money raised by the 5 families is $5.00.
To find the median amount of money raised by the 5 families, we first need to arrange the amounts in ascending order:
$3.00$4.00$5.00$6.00$7.00The median is the middle number in a sorted, ascending or descending, list of numbers. Since there are 5 numbers, the median is the third number in this ordered list. Therefore, the median amount of money raised is $5.00.

Wanahton purified a portion of water with 900 grams of contaminants. Each hour, a third of the contaminants was filtered out.
Let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? Then, write an explicit formula for the sequence, g(n)=?
The sequence g(n) is a geometric sequence with an explicit formula of g(n) = (2/3)^n * 900 grams.
Explanation:The sequence g(n) represents the amount of contaminants (in grams) that remains at the beginning of the nth hour. Each hour, a third of the contaminants is filtered out. To determine whether g(n) is an arithmetic or geometric sequence, we need to examine the change in the amount of contaminants from one hour to the next.
Let's look at the first few terms of the sequence:
g(1) = 900 grams (initial amount)g(2) = 2/3 * g(1) = 2/3 * 900 gramsg(3) = 2/3 * g(2) = 2/3 * (2/3 * 900 grams)From the pattern, we can see that each term of g(n) is obtained by multiplying the previous term by 2/3. Therefore, g(n) is a geometric sequence.
The explicit formula for the sequence g(n) can be written as g(n) = (2/3)^n * 900 grams.

Marta's dog just had six puppies. Four are female (F), and two are male (M). One of the males is brown. Two of the females are brown. All puppies are either brown or white. If Marta randomly gives away puppies to her friends, what is the probability of a friend getting a puppy that is male, brown, or both?
Answer:
Step-by-step explanation:
No of total brown = 2 + 1 = 3 .
probability = 3 / 6
= 1 /2 .
no of males = 2
probability
= 2 / 6
= 1 /3
no of person who is both male and brown = 1
probability = 1 /6
Required probability
= probability of being brown + probability of being male - probability of being both
= 1 / 2 + 1 / 3 - 1 /6
= 4 / 6
= 2 / 3 .
Final answer:
The probability of a friend getting a puppy that is male, brown, or both is 2/3, which is calculated by adding the probability of getting a male puppy and a brown puppy, then subtracting the probability of the overlap (brown male).
Explanation:
The student's question concerns the probability of a friend receiving a puppy that is male, brown, or both, given the conditions of the puppies provided. To calculate this probability, we consider all possible favorable outcomes divided by the total number of outcomes. There are 2 males (1 brown, 1 white) and 4 females (2 brown, 4 total), making a total of 6 puppies. A friend can receive either a male puppy (2 out of 6) or a brown puppy (3 out of 6, since we do not count the brown male twice). Thus, the probabilities need to be added together and the intersection (the brown male counted in both categories) subtracted to avoid overcounting.
We calculate the probability as P(Male) + P(Brown) - P(Brown and Male) = 2/6 + 3/6 - 1/6 = 4/6 or 2/3. Therefore, the probability of a friend getting a puppy that is male, brown, or both is 2/3.

The amount of aluminum varies inversely as the amount of tin. When there are 600 grams of aluminum there are 40 grams of tin. How many grams of aluminum will there be if there is 120 grams of tin
Answer:
There will be 200g of aluminium.
Step-by-step explanation:
We use a rule of three to solve this question.
However, the relationship between the variables are inverse, which means that we use an inverse rule of three. This means that we are going to multiply the values laterally, instead of diagonally(cross multiplication).
We have these following relationships:
600g aluminum - 40g tim
xg aluminium - 120g tin
Multiplying laterally:
[tex]120x = 600*40[/tex]
[tex]x = \frac{600*40}{120}[/tex]
[tex]x = 200[/tex]
There will be 200g of aluminium.
Final Answer:
When there is 120 grams of tin, there will be 200 grams of aluminum.
Explanation:
In problems involving inverse variation, the formula that describes the relationship between two variables (in this case, aluminum and tin) is as follows:
k = xy
where:
- k is the constant of variation,
- x is the amount of aluminum, and
- y is the amount of tin.
Given that there are 600 grams of aluminum when there are 40 grams of tin, we can use these values to find the constant of variation (k). We can set up the equation and solve for k with the given values.
[tex]\[ k = 600 \text{ grams of aluminum} \times 40 \text{ grams of tin} \\\\\[ k = 24000 \text{ (constant of variation)} \][/tex]
Now that we have the constant of variation, we know this constant remains the same even when the amounts of aluminum and tin change, providing the inverse relationship is maintained.
Now we want to find out how many grams of aluminum there will be when there is 120 grams of tin. We set up the inverse variation formula and solve for x now that y is given as 120 grams:
k = xy
Given that k = 24000 from our previous calculation, we find x:
[tex]\[ x = \frac{k}{y} \\\\\[ x = \frac{24000}{120} \\\\\[ x = 200 \text{ grams of aluminum} \][/tex]
Therefore, when there is 120 grams of tin, there will be 200 grams of aluminum.

The wages w (in £) Gordon earns is the number of hours he works n multiplied by his hourly rate r (in £ per hour). Enter a formula for Gordon's wages and enter the wage he would earn if he worked 5 hours at a rate of £10.40 per hou
Answer:
1. w = nr
2. His wage is £52.00
Step-by-step explanation:
1. Given that wages is a function of number of hours worked multiplied by hourly rate
Where n represents hours and r represents rate.
Wage formula is as follows;
Wage (w) = hours (n) * rate (r)
w = n * r
w = nr
2. If he worked 5 hours at a rate of £10.40 per hour
This means
n = 5
r = 10.40
His wage is as follows;
w = nr
w = 5 * £10.40
w = £52.00
Hence, his wage is £52.00
Final answer:
Explanation of Gordon's wages formula and a calculation example for working 5 hours at a specific rate.
Explanation:
The formula for calculating Gordon's wages, w, is given by multiplying the number of hours he works, n, by his hourly rate, r.
A formula for Gordon's wages: w = n * r
Wages earned by Gordon working 5 hours at a rate of £10.40 per hour:
Substitute n = 5 and r = £10.40 into the formula:
w = 5 * £10.40
= £52
The wage Gordon would earn if he worked 5 hours at a rate of £10.40 per hour is £52.

A recipe requires ¾ cup of nuts for 1 batch of muffins. Write the number of batches of muffins that can be made using 7 ½ cups of nuts.
Answer:
10 batches
Step-by-step explanation:
3/4 cups = 1 muffins
15/2 cups = x muffins
For x muffins,
3/4 × X = 15/2 × 1
3x × 2 = 15×4
6x = 60
Divide both sides by 6
6x/6 = 60/6
X = 10
Hence 10 batches of muffins will be made from 15/2 cups of nuts.

The number of hot dogs is 75 while the number of snacks is 100.
The linear equation to solve the question will be:
h + s = 175 ........ i
2.50h + 0.75s = 262.50 ........ ii
From equation i, s = 175 - h ..... iii
Put equation iii into ii
2.50h + 0.75s = 262.50
2.50h + 0.75(175 - h) = 262.50
2.50h + 131.25 - 0.75h = 262.50
Collect like terms
2.50h - 0.75h = 262.50 - 131.25
1.75h = 131.25
h = 131.25/1.75
h = 75
The number of hot dogs is 75 while the number of snacks is 100.

Answer:
4.55%
Step-by-step explanation:
To find the percentage of deaths in relation to the number of cases confirmed, we just need to divide the number of deaths by the number of cases confirmed.
So we have that:
Percentage = Deaths / Cases
Percentage = 170 / 3739
Percentage = 0.0455 = 4.55%
The percentage of deaths in relation to the number of cases is 4.55%
