Steven earns extra money babysitting. He charges $31.25 for 5 hours and $50 for 8 hours. How much would Steven charge for 3 hours?
please help me out on this!
Answer:
$18.75
Step-by-step explanation:
This is kind of a trick question. Instead of giving you 1 example they give you two.
Basically, this question is trying to test your reading skills.
31.25 is being charged for 5 hours. So, how much is being charged in 1 hour?
well, dividing 31.25 by 5 brings us to the result of 6.25. Meaning 1 hour of babysitting costs $6.25
Now that we know the cost of 1 hour, we need to multiply this by 3.
6.25 x 3 = $18.75
we can also 'test' our answer to make sure it is correct by multiplying 6.25 by 8. (doing so is confirming 8 hours of work is $50 at $6.25 per hour)
hope this helpd!
Jane had 5 candy canes Max had 11 candy canes how many candy canes do they have all together
By adding Jane's 5 candy canes to Max's 11 candy canes, we find that together they have 16 candy canes.
Explanation:To find out how many candy canes Jane and Max have all together, we need to add the number of candy canes that each person has. Jane has 5 candy canes and Max has 11 candy canes. So, we will perform a simple addition: 5 (Jane's candy canes) + 11 (Max's candy canes).
The sum is:
5 + 11 = 16
Therefore, Jane and Max have 16 candy canes all together.
To find the total number of candy canes Jane and Max have all together, you simply need to add the numbers of candy canes they each have. Jane has 5 candy canes and Max has 11 candy canes. Adding these numbers together, 5 + 11 = 16.

Two workers produced 86 parts during their working shift. The first worker produced 15% more parts than the second one. How many parts did each worker produce?
The second worker produced 40 parts and the first worker produced 46 parts.
Explanation:To solve this problem, we can set up a system of equations. Let x represent the number of parts produced by the second worker. Since the first worker produced 15% more parts, the number of parts produced by the first worker can be represented as 1.15x. The total number of parts produced by both workers is 86, so we can set up the equation:
x + 1.15x = 86
Combining like terms, we get 2.15x = 86. Divide both sides of the equation by 2.15 to find x:
x = 40
Substituting this value back into the equation, we find that the second worker produced 40 parts. The first worker produced 15% more, so they produced 40 + 0.15(40) = 46 parts.

jack was planting a tree. he was to dig a hole that was 3.25 feet deep for every 5.7 feet of tree height . how deep should he dig the hole for a tree that is 17 feet high
Jack should dig a hole approximately 9.69 feet deep for a tree that is 17 feet high.
Jack needs to dig a hole for a tree that is 17 feet high, based on a requirement that the hole depth should be 3.25 feet for every 5.7 feet of tree height. To calculate the depth of the hole Jack should dig, we will set up a proportion where the depth of the hole is directly proportional to the tree height.
The proportion is as follows: 3.25 feet depth/5.7 feet height = x feet depth/17 feet height. To solve for x (the depth of the hole for a 17-foot tree), we cross-multiply and divide:
(3.25 feet depth * 17 feet height) / 5.7 feet height = x feet depth.
By calculating this, we get:
x = (3.25 * 17) / 5.7 = 55.25 / 5.7 = 9.69 feet.

The graph shows the distance from the car that Laura is as she hikes on the second day of a 2-day hike. Write the equation for the graph.
Laura’s hike can be described by the equation ( y = 6x ), where ( x ) represents time (in hours) and ( y ) represents distance (in miles).
Graph Description:
The graph depicts a linear relationship between time (in hours) and distance (in miles).
The x-axis represents time, ranging from 0 to 5 hours.
The y-axis represents distance, ranging from 0 to approximately 24 miles.
The line starts from the origin (0,0) and extends to the point (5,24), indicating that Laura covered a distance of approximately 24 miles in five hours.
Each grid square along the x-axis represents one hour, and each grid square along the y-axis represents approximately four miles.
Equation for the Graph:
To find the equation of the line, we’ll calculate the slope (m) and the y-intercept (b).
Let’s use two points on the line: (1,0) and (5,24).
The slope (m) can be calculated as follows: [tex][ m = \frac{{y_2 - y_1}}{{x_2 - x_1}} = \frac{{24 - 0}}{{5 - 1}} = \frac{{24}}{{4}} = 6 ][/tex]
The y-intercept (b) is where the line crosses the y-axis (at point (0,0)). Therefore, ( b = 0 ).
The equation of Laura’s hike on the graph is: [ y = 6x ]
Explanation:
The equation ( y = 6x ) represents Laura’s hiking progress. For every hour she hikes, she covers a distance of 6 miles.
The slope of 6 indicates that her speed is consistent (6 miles per hour).
The y-intercept of 0 means that she started at the origin (0 miles) when the hike began.
In summary, Laura’s hike can be described by the equation ( y = 6x ), where ( x ) represents time (in hours) and ( y ) represents distance (in miles).
There are (713)3 ⋅ 70 strawberries in a field. What is the total number of strawberries in the field?
A. 1

D. 7 ^39
Answer:
[tex]7^{39}[/tex]
Step-by-step explanation:
We have been given that there are [tex](7^{13})^3\cdot 7^0[/tex] strawberries in a field.
Using exponent property [tex]a^0=1[/tex], we will get:
[tex](7^{13})^3\cdot 1[/tex]
[tex](7^{13})^3[/tex]
Using exponent property [tex](a^b)^c=a^{b*c}[/tex], we will get:
[tex]7^{13*3}[/tex]
[tex]7^{39}[/tex]
Therefore, the total number of strawberries in the field is [tex]7^{39}[/tex].

Lisa's pet shop has 2 fish tanks. Tank A contains smaller fish who are fed 1 gram of food each per day. Tank B contains larger fish who are fed 2 grams of food each per day. If Tank B contains 2/3 the number of fish that Tank A contains, will Lisa ever feed both tanks the same amount of food? How many of each type of fish of fish would she need to have?
Answer:
in tank A, we need 1 gram of food per fish.
In tank B, we need 2 gramms of food per fish.
If Na is the number of fish in tank A and Nb is the number of fish in tank B.
Then, the amount of food that the tank A needs is:
Na*1g of food
The tank B needs:
Nb*2g of food
And we know that Nb = 2/3*Na
we can replace it and get:
2/3*Na*2g
Then if both tanks need the same amount of food, we should have that both of these equations are equal:
food of tank A = food of tank B
Na*1g = (2/3)*Na*2g
we solve this for Na
Na = (2/3)*Na*2g/1g = (2/3)*Na*2 = (4/3)*Na
Na = (4/3)*Na
This equation has no solution, and from here we can conclude that if Nb = 2/3*Na, she will never give the same amount of food to both tanks.
b) knowing that the amount of food neded in tank A is half the amount for tank B, then we need the doulbe of fish in the tank A than in the tank B
Na = 2*Nb
Lisa cannot feed both tanks the same amount of food under the given conditions. If Tank A has 'a' smaller fish and Tank B has 2/3 of the number of fish in Tank A, then Tank A would require 'a' grams of food while Tank B would require 4/3 'a' grams, which are not the same.
The student is asking whether Lisa can ever feed the same amount of food to both Tank A and Tank B, given that the larger fish in Tank B eat 2 grams of food per day and there are 2/3 the number of fish in Tank B compared to Tank A, which contains smaller fish that eat 1 gram of food per day. To determine if there is a scenario where Lisa can feed both tanks the same amount of food, we will need to set up an algebraic equation.
Step-by-step calculation:
Let the number of smaller fish in Tank A be represented by the variable a.The number of larger fish in Tank B would then be 2/3a as Tank B contains 2/3 the number of fish that Tank A contains.Calculate the total food for Tank A: a fish × 1 gram/fish = grams.Calculate the total food for Tank B: 2/3a fish × 2 grams/fish = 4/3a grams.Set the total food for both tanks equal to each other to find the condition when Lisa feeds the same amount to both tanks: a = 4/3a.Solve for a: This equation has no solution because Tank A cannot contain the same number of grams of food as 4/3 times itself.Therefore, Lisa can never feed both tanks the same amount of food unless one of the conditions changes, like the amount of food fed to the fish or the ratio of fish between the tanks.

A blueprint of a house shows a wall that is 5 inches long. If the blueprint is drawn to a scale of 1:60, what is the actual length of the wall in the house?
Using a scale of 1:60, the actual length of a wall in the house, depicted as 5 inches on the blueprint, is 25 feet.
The correct option is c) 25 feet
To find the actual length of the wall in the house, we need to use the scale factor provided by the blueprint, which is 1:60. This means that 1 unit on the blueprint represents 60 units in reality.
Since the wall on the blueprint is 5 inches long, we can calculate the actual length of the wall by multiplying the length on the blueprint by the scale factor:
Actual length = Length on blueprint × Scale factor
= 5 inches × 60
= 300 inches
To convert inches to feet, we divide by 12 (since 12 inches = 1 foot):
Actual length (in feet) = [tex]\frac{300 inches}{12}[/tex]
= 25 feet
Therefore the correct answer is option C) 25 feet.
The question probable may be:
A blueprint of a house shows a wall that is 5 inches long. If the blueprint is drawn to a scale of 1:60, what is the actual length of the wall in the house?
A) 5/60 feet
B) 12 feet
C) 25 feet
D) 36 feet
