A can of orange and a chocolate bar cost £1.30 together. Two cans of orange and a chocolate bar cost £2.15 together. How much would three cans of orange and four chocolate bars cost?
Solving the system of linear equations provided, we find that the cost of a can of orange is £0.85 and a chocolate bar costs £0.45. Therefore, three cans of orange and four chocolate bars would cost £4.35.
The student's question involves solving a system of linear equations to find the individual prices of a can of orange and a chocolate bar. Once the individual prices are determined, the student wants to know the total cost of three cans of orange and four chocolate bars. Here's a step-by-step approach to solve this problem:
Let the price of a can of orange be 'O' and the price of a chocolate bar be 'C'.
The first equation from the given information would be O + C = £1.30.
The second equation would be 2O + C = £2.15.
Subtract the first equation from the second to find the price of an additional can of orange, which gives us O = £0.85.
Substitute the value of O in the first equation to find C, which yields C = £0.45.
Now, calculate the cost of three cans of orange and four chocolate bars: 3O + 4C = 3(£0.85) + 4(£0.45) = £2.55 + £1.80 = £4.35.
So, three cans of orange and four chocolate bars would cost £4.35 together.

Loudness, or the intensity of sound, is measured in decibels. The sound level of a television is about 70 decibels, which is considered a safe hearing level. A food blender runs at 20 decibels higher than a TV, and a jet engine's decibel reading is 40 less than twice that of a blender. At this level, exposure can cause hearing loss. Find the intensity of the sound of a jet engine.

Daniel is completing a home project. He needs 13 pieces of wood, each 1 1/2 feet long, to complete the project. How much wood does Daniel need to complete his home project?
8 2/3 ft
11 1/2 ft
14 1/2 ft
19 1/2 ft
Answer:
Daniel will need [tex]19\frac{1}{2}[/tex] feet wood to complete his home project.
Step-by-step explanation:
We are told that Daniel needs 13 pieces of wood, each [tex]1\frac{1}{2}[/tex] feet long, to complete his home project.
To find total amount of wood needed we will multiply number of wood pieces by length of each wooden piece.
First of all we will convert our mixed fraction to improper fraction as: [tex]1 \frac{1}{2} =\frac{3}{2}[/tex]
Now let us multiply our values.
[tex]13*\frac{3}{2} =\frac{39}{2}[/tex]
Now we will convert this improper fraction to mixed fraction to find our final answer.
[tex]\frac{39}{2}=19\frac{1}{2}[/tex]
Therefore, Daniel needs [tex]19\frac{1}{2}[/tex] feet wood to complete his home project.

Who is the manager of the pharmacy?
Where is the pharmacy located in the store?
How many pharmacists are there in the pharmacy?
How many hours do you spend at the pharmacy each month?
Answer:
How many hours do you spend at the pharmacy each month?
Step-by-step explanation:
A statistical question is a question that will have variable answers. It will not have a single answer. Like - How tall are the students in your class?
So, here the answer is -
How many hours do you spend at the pharmacy each month?
As here, the answer can be variable. Some days it can be 8 hours, some days it can be 12 hours.
There are two sizes of trucks available: larger truck with a 2.5-ton payload, and smaller trucks with 1.5-ton payload. To unload a freight train 21 larger trucks are needed . How many smaller trucks would be needed for the same job?
Answer:
35 smaller trucks.
Step-by-step explanation:
Given:
i) The larger truck with a 2.5-ton payload, and smaller trucks with 1.5-ton payload.
ii) To unload a freight train 21 larger trucks are needed .
Total load of the freight train = 21 times 2.5 tons
= 21 × 2.5
= 52.5 tons
To find the number of small trucks needed, we need to divide 52.5 by 1.5
= 52.5 ÷ 1.5
= 35 small trucks needed.
So, to unload the freight, we need 35 smaller trucks.
Martin had 7 pounds of grapes left, and he gave away 2/5 of them. Explain how to use compatible numbers to estimate the amount of grapes he gave away.
Answer:
Step-by-step explanation:
The amount of grapes that he gave away is 3.5 pounds.
Number of grapes with Martin = 7 pounds
Fraction given away = 2/5
In this case, to use compatible numbers, we have to find a fraction that's close to 2/5 which will be 1/2.
Then, we have to multiply 1/2 by 7 and this will be:
= 1/2 × 7
= 3.5
In conclusion, the amount of grapes that he gave away is 3.5 pounds.

rosa, roberto, andrea, and inno find an estamate for the square root of ten who has proposed the best solution
Rosa, use the square root of 9 and the square root of 25
Roberto, use the square root of 4 and the square root of 90
Andrea, use the square root of 11 and the square root of 12
Inno, use the square root of 9 and the square root of 16
Final answer:
Inno's solution of using the square root of 9 and 16 is the best estimate for the square root of ten, as it provides a narrower and more accurate range for the estimate.
Explanation:
To estimate a square root that is not a perfect square, one strategy is to find integers that the number falls between, and then those integers' respective square roots give us a range within which the square root of the number will fall.
Rosa and Inno's approaches are similar and most appropriate because they both use 9 and another square number that is close to 10.
Rosa uses the square roots of 9 and 25. Since the square root of 9 is 3, and the square root of 25 is 5, we know that √10 is a little more than 3, because 10 is closer to 9 than it is to 25. Inno uses the square roots of 9 and 16. Since the square root of 16 is 4, √10 is closer to 3 than 4 because 10 is closer to 9.
Therefore, Inno's solution gives a closer estimate of the square root of 10, as it falls between 3 and 4 (and closer to 3), and this is the best solution among those proposed.
