10) 1 gallon of water for every inch of the fish's body length.
a) 2 1/2 inches long fish needs 2 1/2 gallon of water.
b) tank: l = 7 inches ; w = 5 inches; h = 7 ; volume = 7in * 5in * 7in = 245 in³
c) no. her fish tank is not large enough for the fish.
volume of 1 gallon of water is 231 in³, water needed is 2 1/2 gallon, so 5/2 * 231 in³ = 577.50 in³ volume.

11) volume = 7in * 3.5in * 1.75 in = 42.875 in³
weight of the brick = 0.1 pound per cubic inch ⇒ 42.875 in³ * 0.1 lb = 4.2875 pounds
weight of the gold bar = 0.7 pound per cubic inch ⇒ 42.875 in³ * 0.7 lb = 30.0125 pounds

12) l = 55cm ; w = 40cm ; h = 30 cm
volume = 55cm * 40cm * 30cm = 66,000 cm³

Select the choice that translates the following verbal phrase correctly to algebra: y less than 21

Answers

y (y) less than (minus) 21 (21
y-21

21-y
This is because it says "less than" which is a way to say subtraction. So if you want y less than 21 it would be written as 21-y.

y = 1 over 3. x − 1
y = 3x − 1
y = −x + 1 over 3.
y = 3x + 1

Answers

it's y-intercept (0,-1) and (1,2)
so
slope = (2+1)/(1-0) = 3

equation should be y = 3x − 1

answer: y = 3x − 1

Answer:

y = 3x − 1

Show how to multiply 46.93×1.8

Answers

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.

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

What is the value of P for the following triangular prism?

Answers

If P stands for perimeter:

Perimeter of 1 triangle = 4 cm + 4 cm + 2.8 cm = 10.8 cm
28 mm is converted to cm to make all units similar.
1cm = 10 mm so, 28mm * 1cm/10mm = 28cm/10 = 2.8cm

There are 2 triangles: 10.8cm x 2 = 21.6 cm

We add up the length of 5cm, there are 3 lengths. 5 cm x 3 = 15cm

Perimeter = 21.6cm + 15 cm = 36.6cm

Among the choices, only the 1st option is closest to the answer at 36cm.

The 2nd choice is irrelevant because its unit of measure is in mm.
