How do u square a scale factor?

Answers

You multiply the area by the scale factor twice. Here is an example: if we have a rectangle that has a length 3 and a height of 4 and the scale drawing with a scale factor of 2, how many times bigger is the scale drawings area? The original shape is 3 by 4 so we multiply those to find the area of 12 square units.

hope it helps!!!

Answer:

The scale factor for area is found by squaring the scale factor for length. Thus the scale factor for area is s2. If this is reversed, a method is provided for solving the problem being investigated. The scale factor for area is 2.

The first three terms of an arithmetic sequence are as follows.

Answers

the next two would be 11 and 7 because it goes down by 4 every time

Answer:

11 and 7

Step-by-step explanation:

To determine the answer, you must find the pattern in the first three numbers. It appears that each number is 4 less than the previous number, such as 15 is 4 less than 19 and 19 is 4 less than 23.

So, follwing this patern, subtract 4 from 15 to get the next number. 15-4=11

Next, subtract 4 from 11 to get the last number. 11-4=7

Answers

Answer:

39 degrees.

Step-by-step explanation:

the line is 180 degrees. one of the angles is 51 degrees and another is 90 degrees because it shows us a square. 51 + 90 is 141. 180 - 141 is 39. so 39 degrees is your answer.

Step-by-step explanation:

c + 51° + 90° = 180°

c + 141° = 180°

c = 180° - 141°

c = 39°

An account is opened with an initial balance of $950 and a simple annual interest rate of 1.6%. What is the balance after 5 years

Answers

the answer is $1,026.

Solving: Use Simple interest formula, I=Prt.

Make the rate into a decimal (1.6% -> 0.016)

plug in the numbers into the formula. 950 x 0.016 x 5 = 76$.

76$ will be our interest, now to find the balance we would have to add the the starting money (950) with our interest (76$), resulting in our answer of $1,026 after 5 years.

$1,026. This is because $950 multiplied by 1.6% is equal to $15.20. This multiplied by 5 years is equal to $76. $950 multiplied by $76 is equal to $1,026.

estimate the value Square Root 48 to your best judegment and explain why.

Answers

Answer:

Step-by-step explanation:

Square Root of 48: √48 = 6.928Square of 48: 482 = 2304

Answer:

6.8 or 6.9 (Estimation).

Step-by-step explanation:

The number 48 is not a perfect square. Using the approximation approach, we can get the square root of 48. We may utilize the long division approach to get an exact result. We discover square numbers close to 48 using the approximation approach. We can see that 36 and 49 are perfect square numbers that are close to 48. 36 has a square root of 6 while 49 has a square root of 7. As a result, the square root of 48 must be between 6 and 7, and preferably closer to 7 because 48 is closer to 49. This approach simply provides an approximation. We may use the long division approach to determine a more precise decimal number for 48.

South Pole Expedition

Your Outdoor Adventures class is providing guidance to a group that is on an expedition to the South Pole. There are 5 people on the expedition.

Due to the extreme climate and conditions, each person in the group needs to consume 5600 calories per day. The table shows the three foods that will make up their total daily calories, along with the number of calories per unit and the daily needs by percentage.

[ attached image ]

The map shows the current location of the group, as well as the location of the South Pole and the base camp. Each unit on the grid represents 5 miles.

[ attached image ]

The group thought there was enough food for all 5 group members to complete the trip, with each person getting the required 5600 calories per day. They discover that 2 of the crates they brought are missing.

Each crate contains:
• 80 biscuits
• 50 packages of pemmican
• 10 packages of butter and cocoa

Using the map, create a plan for the rest of the trip that includes taking as many group members as possible to the South Pole, and back to base camp, passing through the groups current location, while sending the rest of the group members directly back to base camp. Remember that each person must have 5600 calories of food per day until he or she gets back to base camp.

Be sure to explain how you came up with your plan. Include all work necessary to support your answer.

Answers

Answer: the answer is that each 80 calories is worth 40 daily calories

Step-by-step explanation:

To be able to pal the calories consumption, one can total the amount of people together (5people x 5groups = 25) and then begin to share the food using 5600 calories per day.

What is calorie?

This is known to be a form of a measurement, as it is the the amount of energy that is often given off when the human body breaks down food.

Since there are 25 people that needs 5600 calories per day.

The numbers of crate were not given so answer will be limited to 2 crate.

2 crate has:

160 biscuit100 pemmican20 butter and cocoa

From the table, having one single biscuit, pemmican and butter and cocoa gives 100% of the daily calories needs.

Therefore each person should have a single biscuit, pemmican and butter and cocoa.

Please find two expressions that are equivalent to 2(3j + 4 + 9j)

Answers

Answer:

Heyo! I could help you, but I have a question!

Step-by-step explanation:

Is this a multiple choice question, or would you like me to solve it on my own?

to solve this, distribute the 2 amongst 3j+4+9j

2(3j)+2(4)+2(9j)

this would end up being 6j+8+18j, which could be a possible solution to the equation, but it’s not reduced

reduced it by combining like terms to get 24j+8

or, you can make the equation even simpler by combining like terms in the parentheses in the initial 2(3j+4+9j)

that would end up being 2(12j+4)

so, i would say the two equations would be 2(12j+4) and 24j+8
