students collected 600 cans for the canned food drive that was 80% of their goal how many more cans do they need to collect to reach their goal
Answers
Answer: 150
Step-by-step explanation:
Let x be the total number of cans that was students' goal.
Given : Students collected 600 cans for the canned food drive that was 80% of their goal .
We can write 80% as 0.80
Then, we have
[tex]0.80x=600\\\\\Rightarrow\ x=\dfrac{600}{0.80}=750[/tex]
Thus, The students' goal of collecting cans for the canned food drive = 750 cans
Now, the number of food cans required to collect to reach the goal= 750-600=150

what is the value of x
Answers
Solve for x.
4x + 7 = 5(x - 4)
4x + 7 = 5x - 20 <-- Distribute the 5
4x = 5x - 13 <-- Subtract 7 from each side
-x = -13 <-- Subtract 5x from each side
x = 13 <-- Divide both sides by -1
So, x is equal to 13.

1. Use the graph for Parts A–D.
A. Is the relation a function? Explain.
B. What is the domain of the relation?
C. What is the range of the relation?
D. What is the value of y when x = 2? Explain.
Answers
- The relation is not a function due to multiple y-values for the same x-value.
- Domain: {-4, -3, 2}
- Range: {0, 2, -3}
- Value of y when x = 2: -1
Let's analyze the graph and address each part:
A. Is the relation a function? Explain.
- A function is a relation where each input (x-value) corresponds to exactly one output (y-value).
- Looking at the graph, we see that there are two different y-values for x = -3: (x = -3, y = 2) and (x = -3, y = -3).
- Since there are multiple y-values for the same x-value, the relation is not a function.
B. **What is the domain of the relation?
- The domain consists of all the x-values represented in the graph.
- From the graph, we can identify the following x-values: -4, -3, 2.
- Therefore, the domain of the relation is {-4, -3, 2}.
C. What is the range of the relation?
- The range consists of all the y-values represented in the graph.
- From the graph, we can identify the following y-values: 0, 2, -3.
- Therefore, the range of the relation is {0, 2, -3}.
D. What is the value of y when x = 2? Explain.
- To find the value of y when x = 2, we look at the graph.
- At x = 2, the corresponding y-value is -1.
- Therefore, the value of y when x = 2 is -1.

This means that in 1 hour, Amelia biked 20 miles.
Her distance changed at a unit rate of 20 miles per hour, so that was her speed.
For the second part, take a look at the axis labeled "Time (hours)" and find the notch labeled "1". Notice where its gridline hits that red line, and notice what the corresponding notch is on the axis labeled "Distance (miles)". That notch will give you your distance for the question.
The third answer should have the same result as the second; by finding the distance she traveled in one hour, you've already found her "unit rate" in miles per hour.

Answers
Therefore, the number of absent students can be calculated by multiplying the percentage by the total number of students as follows:
number of absent students = (3.75/100) * 320 = 12 students
This means that the number of present students is:
320 - 12 = 308 students
Scientists were studying bears by catching, tagging, and releasing 24 bears. A month later, the scientists come back and catch 4 bears, of which 2 are tagged. Assuming that the catch is representative, how many bears are there?
Answers
Final answer:
The mark and recapture method is used to estimate the size of a population. In this case, 24 bears were initially tagged and 4 bears were recaptured, 2 of which were tagged. The estimated population size can be calculated using the mark and recapture formula as (24 * 4) / 2 = 48 bears.
Explanation:
The mark and recapture method is used to estimate the size of a population. By catching, tagging, and releasing a known number of individuals and then recapturing a second sample, scientists can calculate an estimate of the total population size. In this case, scientists initially tagged 24 bears and then recaptured 4 bears, 2 of which were tagged. Using the mark and recapture formula, the estimated population size can be calculated as follows:
Number of initial tagged individuals: 24
Total number of individuals in the second sample: 4
Number of tagged individuals recaptured in the second sample: 2
Estimated population size = (Number of initial tagged individuals * Total number of individuals in the second sample) / Number of tagged individuals recaptured in the second sample
Using this formula, the estimated population size of bears in this case would be (24 * 4) / 2 = 48 bears.
Nathaniel's sister has 5/6 as many songs on her MP3 player as he has on his MP3 player. His sister has 35 songs. How many songs does Nathaniel have?
Answers
Answer:
42 songs.
Step-by-step explanation:
Let x represent the number of songs Nathaniel's has.
We have been given that Nathaniel's sister has 5/6 as many songs on her MP3 player as he has on his MP3 player. This means his sister has [tex]\frac{5}{6}x[/tex] songs.
We are also told that his sister has 35 songs. We can represent our given information in an equation as:
[tex]\frac{5}{6}x=35[/tex]
Let us solve for x.
[tex]\frac{6}{5}\cdot \frac{5}{6}x=\frac{6}{5}\cdot35[/tex]
[tex]x=6\cdot 7[/tex]
[tex]x=42[/tex]
Therefore, Nathaniel has 42 songs.

Let us say that:
T = numbers from 2-9
Z = numbers from 0-9
X = all except 1 (0, 2-9)
If a number begins with 1:
1 _ _
Then we can have
1 1 Z (10 numbers)
1 X 1 (9 numbers)
So a total of 19.
Now if a number starts with 2-9
T _ _
The second digit must be 1
T 1 _
but the third can be anything so
T 1 Z = 8 * 1 * 10 = 90 numbers
Total = 99

where do young tigers swim
Answers
Young tigers, also known as tiger cubs, typically swim in bodies of water such as rivers, streams, lakes, and ponds found within their natural habitat.
Tigers are known to be excellent swimmers and are generally comfortable in water.
They use swimming as a means to cool off, explore their surroundings, and sometimes to hunt or catch prey.
Swimming also helps tiger cubs develop their physical abilities and gain confidence in the water.
Thus, it's important to note that tigers are found in various habitats across Asia, including mangrove swamps, grasslands, and forests, so the specific locations where tiger cubs swim may vary depending on their environment.

Cynthia Besch wants to buy a rug for a room that is 20 ft wide and 31 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 350 square feet of carpeting. What dimensions should the rug have?
Answers
620/2=310
20/2=10
31/2=15.5
The dimensions should be 10*15.5
Final answer:
Cynthia should calculate the dimensions of the rug by solving the quadratic equation derived from the area she can afford and the dimensions of her room, taking into consideration the width of the uniform strip she wants to leave around the rug.After finding [tex]\( w \), the dimensions of the rug will be \( (20 - 2w) \) ft by \( (31 - 2w) \) ft.[/tex]
Explanation:
To find the dimensions of the rug, we need to subtract the width of the strip left around the rug from the width and length of the room.
The area of the room is given by [tex]\( A_{\text{room}} = W \times L \).[/tex]
Cynthia wants to leave a uniform strip of floor around the rug. This means that the dimensions of the rug will be reduced by twice the width of the strip. So, the dimensions of the rug will be [tex]\( (W - 2w) \times (L - 2w) \).[/tex]
Given that she can afford to buy 350 square feet of carpeting, the area of the rug must be equal to 350 square feet.
So, we have the equation:
[tex]\[ (W - 2w) \times (L - 2w) = 350 \][/tex]
Substituting the given values:
[tex]\[ (20 - 2w) \times (31 - 2w) = 350 \][/tex]
Expanding the equation:
[tex]\[ 620 - 82w - 40w + 4w^2 = 350 \][/tex]
Simplifying:
[tex]\[ 4w^2 - 122w + 620 = 350 \][/tex]
[tex]\[ 4w^2 - 122w + 270 = 0 \][/tex]
Now, we can solve this quadratic equation for w . Once we find the value of w , we can calculate the dimensions of the rug.
After finding [tex]\( w \), the dimensions of the rug will be \( (20 - 2w) \) ft by \( (31 - 2w) \) ft.[/tex]

A teacher deposits $3,000 in a retirement fund. If she doesn't add any more money to the fund, which earns an annual interest rate of 6%, how much money would she have in 1 year?
Answers
Take 6% of 3000 and add it to 3000. So basically turn the 6% into a decimal which would be 0.06, and multiply the 3000 by it. So, 3000 x 0.06 which equals 3,180. I hope this time it helped :) message me if you need further instructions.
After one year, the teacher would have $3,180 in the retirement fund without adding any more money to it.
To calculate the amount in the retirement fund after one year, we need to take into account the principal amount deposited and the interest earned over that period. The formula to calculate the total amount after one year is:
Total Amount = Principal Amount + (Principal Amount * Interest Rate)
Where:
Principal Amount = $3,000 (the initial deposit)
Interest Rate = 6% (expressed as a decimal, which is 0.06)
Now, we can plug the values into the formula:
Total Amount = $3,000 + ($3,000 * 0.06)
Total Amount = $3,000 + $180
Total Amount = $3,180

To find the number of sculptures in the museum, we add the number of modern and antique train paintings and then subtract 76 from the total because there are 76 more paintings than sculptures. The museum has 2,134 sculptures.
The student asked how many sculptures are in the museum, given the number of modern train paintings and antique train paintings, and also knowing there are 76 more paintings than sculptures. To find out the number of sculptures, we first add the number of modern and antique paintings together: 1,763 + 447 = 2,210 paintings in total. Since there are 76 more paintings than sculptures, we subtract 76 from the total number of paintings to find the number of sculptures: 2,210 - 76 = 2,134 sculptures.

A seafood restaurant claims an increase of $1,750.00 over its average profit during a week where it introduced a special of baked clams
a. If this is true, how much extra profit did it receive per day?
b. if it had, instead, lost $150 per day, how much money would it have lost for the week?
c. If it's total loss was $490 for the week, what was its average daily change?
Answers
a. 1,750 is the amount gained over 1 week. Let’s divide. 1,750/7 is 250. If that is true, then the seafood restaurant received $250 of extra profit each day.
b. This is the loss of $150 per day. To find the answer to this problem, all you have to do is 150 * 7. When you do that, you get 1,050. The restaurant would’ve lost $1,050 for the week.
c. This is the lost of $490 in one week. Again, to find the answer to this, divide. 490/7 = 70. The average daily change was $70.
