Show how to multiply 46.93×1.8

Answers

Answer 1

Answer: To start off this is multiplication and not addition nor subtraction where you have to line up your numbers like 46.93+ 1.98No, instead you put them in any order such as46.93x. 1.98---------------37544421370+ 469300------------------92.9214 ------> This is your answer!1)Multiply the 3 in 46.93 to the 8 in 1.98 which is 24. 2) Then you multiply the 9 in 46.93 to the 8 in 1.98 which gives you 72 and don't forget to add the 2 from 24. You get 74. 4)You then multiply the 6 in 46.93 to the 8 in 1.98 and you get 48, add the 7 from 74, and you get 55. 5) You multiply the 4 in 46.93 to the 8 in 1.98 and you get 32, plus the 5 from 55 and you get 37. Your first answer should be 37544.6) After you get this answer, you add a zero underneath the 4 in the one's place from your previous answer. 7) This step might be a little hard to remember, but you do the same procedure as you were doing in steps 1-6. This time on the other hand, you multiply each value in 46.93 to the 9 in1.98. 8)After completing those exact steps, your secondary answer should be 421370. 9) Once having this answer, you multiply 46.93 to the 1 in 1.98 and your third answer should be 469300. 10) The next step is to add up all three of your answers together and you get the final answer. You should be getting 929214. 11) The last and final step is to count the spaces of decimals your multiples' have which are 4, and you move 4 spaces to the left and you get 92.9214.

Answer 2

Answer:

Final answer:

To multiply 46.93 and 1.8, you treat 1.8 as 18, perform the multiplication, and then reinsert the decimal in the right spot. After carrying out these steps, you'll arrive at the result of 84.474.

Explanation:

To multiply the numbers 46.93 and 1.8, you can use the standard multiplication algorithm. Start by thinking of 1.8 as 18, but remember to put the decimal back in the result. Here are the steps:

Multiply 18 by 3 (the number in the hundredths place of 46.93). The result is 54. Write down 54.
Multiply 18 by 9 (the number in the tenths place of 46.93) and add the carried over 5 from the last step. The result is 167. Write down 167, but shift it one place to the left.
Multiply 18 by 6 (the number in the ones place of 46.93). Write this down, shifted two places to the left.
Multiply 18 by 4 (the number in the tens place of 46.93). Write this down, shifted three places to the left.
Add up all the lines. The result should be 84474.
Count how many decimal places are in the numbers you are multiplying. In this case there are two (46.93 has two, 1.8 has one). So put a decimal in your result two places from the right. The final answer is 84.474

Answers

The coach can select the captain in 20 ways (i.e. from all the available 20 players), and he can select the co-captain in 19 ways (i.e. after selecting the captain, there will be 19 people left).
Therefore, the coach can select the captain and the co-captain in 20 x 19 = 380 ways.

Answer:

Step-by-step explanation:

1. Number of peoples available to choose from = 20

$\text{Ways of selecting the captain from 20 people = }_(1)^(20)\textrm {C}=20$

After selecting the captain number of people left among which co captain can be selected = 20 - 1 = 19

$\text{Ways of selecting the co captain from 19 people = }_(1)^(19)\textrm {C}=19$

Hence, Number of ways a coach select the captain and co-captain of a team from a group of 20 people = 20 × 19 = 380

Therefore, The correct option is C. 380

2. Total number of players = 7

Number of players to be selected = 5

$\text{So, number of ways of selecting 5 players out of 7 = }_(5)^(7)\textrm {C}=21$

Therefore, The correct option is A. 21

3. Total number of outcomes = 20

The digits 1, 2, 3, 4, 5, 6 represent the student who make a C

x= $\frac{-4+/- \sqrt{4^(2)-4(1)(-7)} }{2(1)}$
x= $(-4+/- √(16+28) )/(2)$
x= $(-4+/- √(44) )/(2)$
x= $(-4+/- 2√(11) )/(2)$
x= $-2+/- √(11)$

x= $-2+ √(11)$ or $-2- √(11)$

Armando scoops out a bowl of 32 nuts. About how many should he expect to be cashews? A. 5 B. 6 C. 9 D. 18

Answers

1) A. Biased because the population could be uneven. Too many of one ethnicity, too many of one gender, etc.

2) I believe this one is C. because there are not enough people. You need to survey the majority of parents instead of a selected few.

3) There are 80 green marbles per 500, therefore calculate the percentage. $(80)/(500)=0.16$ or $16$ percent. Multiply $16$ percent or $0.16$ times 25. It gives you $4$ .

4) This one is a probability thing too. For every 500 batteries, there are 3 that are defective, therefore, $(3)/(500)= 0.006$ .

$0.006*12000 = 72$

5) Yet another one. Add up all the nuts and you get $48$ . The chance of getting a cashew from these $48$ is: $(9)/(48)=0.1875$ .

Therefore: $0.1875*32=6$
