Which shows 54^2 − 46^2 being evaluated using the difference of squares method

Answers

Answer 1

Answer: We use the formula: a^2 - b^2 = (a - b )(a + b);
54^2 − 46^2 = (54 - 46)(54 + 46) = 8 x 100 = 800;

The GDP is $11,465.2 billion. The population is 249,793,675. Find the per capita GDP.

Answers

Answer: $ 45898.68

Step-by-step explanation:

Given: Population = $249,793,675$

GDP = $11,465.2 billion

Since we know that 1 billion = 1,000,000,000

Therefore, GDP = $11,465,200,000,000

Also, the per capita GDP is calculated by :-

$\text{per capita GDP}=\frac{\text{GDP}}{\text{Population}}\n\n=(11,465,200,000,000)/(249,793,675)\n\n=45898.6801808\approx\$45898.68$

Hence, the per capita GDP = $ 45898.68

it would be 45898.68 $ for the capital gdp

Brents pick up truck can carry 1/5 ton. Ninas pick up truck can carry 500 lb whose pick up truck can carry more weight?

Answers

Nina can pick up more weight.

1 ton = 2,000 pounds, so 2000 ÷ 5 = 400 and 500 > 400

the suntracker grows at a rate of 2.5 CM per day after the first 60 days.If this sunflower is 195 cm tall when it is 60 days old witer a expression to represent suntrackers height after 22 days or when it is 82 days old exspain how you found your answer, other sunflower is 235 cm

Answers

Given:
height at 60 days old - 195cm
height after 60 days old - 2.5cm per day

total height = 195 cm + 2.5cm(x - 60)
x = day measured

22 days old

total height = 195cm + 2.5cm(22-60)
t.h = 195cm + 2.5cm(-38)
t.h = 195cm - 95cm
t.h = 100 cm

82 days old

total height = 195cm + 2.5cm(x-60)
t.h = 195cm + 2.5cm(82-60)
t.h = 195cm + 2.5cm(22)
t.h = 195cm + 55cm
t.h = 250cm

Ms. Howard wrote a test. Part A had true/false questions, each worth points. Part B had multiple choice questions, each worth points. She made the number of points for Part A equal the number of points for Part B. It was the least number of points for which this was possible.

Answers

Full question attached

Answer and explanation:

Since x = number of true or false questions correct

And y = number of multiple choice questions correct

And each question for x =2 points

each question for y=3 points

since she then needs a total score of more than 93 to pass, we add up total correct questions and

Inequality equation = 2x +3y >93

Final answer:

To find the least number of points for which the number of points for Part A is equal to the number of points for Part B, we need to find the least common multiple (LCM) of the values of points for true/false questions and multiple choice questions.

Explanation:

To find the least number of points for which the number of points for Part A is equal to the number of points for Part B, we need to find a common multiple of the values of points for true/false questions and multiple choice questions. Let's assume the number of points for true/false questions is x and the number of points for multiple choice questions is y. We need to find the least common multiple (LCM) of x and y. Once we find the LCM, that will be the minimum number of points for which the number of points in Part A is equal to the number of points in Part B.

For example, if the number of points for true/false questions is 4 and the number of points for multiple choice questions is 6, we can find the LCM as follows:

List the multiples of 4: 4, 8, 12, 16, 20, 24, ...
List the multiples of 6: 6, 12, 18, 24, 30, ...
Find the smallest number that appears in both lists: 12

Therefore, the least number of points for which the number of points in Part A is equal to the number of points in Part B is 12.
