Which of the following steps could be used as a shortcut method to multiply 12 by 50?A. Divide 12 by 2, then multiply that result by 50
B. Add 12 and 50, then multiply that result by 10
C. Multiply 12 by 100, then divide that result by 2
D. Multiply 12 by 5 and then multiply that result by 100

Answers

Answer 1

Answer: We must remember that 50 x 2 = 100. Multiplying numbers by 100 would be easier since all we have to do is add two zeros after. For example, 62 x100 = 6200. Since we multiplied a number by 2, we must divide it by 2 after getting the product. To make this more clearer, for 12 x 50, for example, we have 12 x 50 = (12 x 100)/2 = 1200/2 = 600 Thus, the answer is C.

Answer 2

Answer: The answer is C. Multiply 12 by 100, then divide that result by 2.

How many packages will 5 1/2 pounds of raisins fill if each package holds 9 ounces

Answers

well there are 16 ounces in a pound... so u need to have 16 x 5 = 80 and 16 x 1/2 = 8 so 80 + 8 = 88. then u need to do 88 ÷ 9 which would equal less than 10 but greater than nine, so u need to round it to the next whole number so it would be 10 because its okay if one container isn't completely full

Priya is playing a game where she earns online badges for scoring higher than the mean score on a level. After the tenth level, she scores 3,540 points, which is 2 standard deviations above the mean score of 3,110 points.What is the standard deviation of scores for the tenth level?

a.)215
b.)311
c.)354
d.)430

Answers

If score of 3,540 points is 2 standard deviations above the mean score of 3,110, then:
3,110 + 2 s= 3,540
2 s = 3,540 - 3,110 = 430
s = 430 : 2
s = 215
Answer: A) The standard deviation is 215.

The standard deviation of scores for the tenthlevel is 215 and is denoted as option A.

What is Standard deviation?

This is defined as the measure of the amount of variation or dispersion of a set of values.

We were told that score of 3,540 points is 2 standard deviations above the mean score of 3,110 therefore,

3,110 + 2 s= 3,540

2 s = 3,540 - 3,110

2s = 430

s = 430/2

s = 215

Find the greatest common polynomial. 8r³-6r²

Answers

0,3/4 GCP=3/4 is the answer give brainliest!

Final answer:

The greatest common polynomial of 8r³-6r² is 2r². The expression when factored using the greatest common polynomial becomes 2r²(4r-3).

Explanation:

To find the greatest common polynomial of the expression 8r³-6r², we must look for the greatest common factor or polynomial. In this case, we observe that both terms, 8r³ and 6r², have a common factor of 2r².

To factorize the expression, we simply divide each term by the greatest common factor we identified. The factored expression is 2r²(4r-3).

So, the greatest common polynomial in the given expression is 2r².

Mr. Chong deposits RM5 000 into a fixed deposit account with 4% interest rate compounded every 3 months for a period of 3 years. Calculate the amount of interest accrued after the third year。 fast please tq

Answers

Answer:

The interest is 634.13.

Step-by-step explanation:

Amount deposit , P = 5000

Interest, R = 4 % so, R = 4/4 = 1 %

Time, T = 3 years quarterly

n = 3 x 4 = 12

Let the amount is A.

Use the formula of the compound interest

$A = P \left ( 1 + (R)/(100) \right )^n\n\nA = 5000 \left ( 1 + (1)/(100) \right )^(12)\n\nA = 5634.13$

So, the interest is

I = A - P = 5634.13 - 5000 = 634.13
