NEED HELP ASAP Marsha and Tian are making table decorations for a party. Marsha made 2/9 of a decoration in half and hour. Tian made 2/3 of a decoration in the same amount of time. How much more of a decoration did Tian make in a half and hour?_______

How much would they make in a half hour if they worked together?______

Answers

Answer:

4/9 and 8/9

Step-by-step explanation:

$(2)/(3)$ and $(2)/(9)$ you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer.

a snail moves at a speed of 2.394 inches per minute. if the snail keeps moving at this rate about how many inches will it travle

Answers

The answer completely depends on how many minutes pass before the snail either gets bored and stops, or else drops in its tracks from starvation. If that number is represented by the symbol ' Q ', then the total number of inches traveled ' T ' will be represented precisely by the function [T=2.394Q].

Answer: I have no idea how this Mr. got something like T or Q. But anyways, the answer is 14 in if you are asking for "about".

Step-by-step explanation:

2.394 = 2

7.489 = 7

So, 2 x 7 = 14 in

Please help!Bill and Ron build towers using blocks. The expression 4b + 2 represents the number of blocks Bill uses. The expression 8b – 5 represents the number of blocks Ron uses.

Complete the expression to represent the total number of blocks Bill and Ron use.

__ b - __

Answers

They use 9 blocks each, a total of 18 blocks.

Bill: 4b + 2
Ron: 8b - 5

To look for the value of b; I assume that both used the same number of blocks.

4b + 2 = 8b - 5
4b - 8b = -5 -2
-4b = -7
-4b/-4 = -7/-4
b = 1.75

Bill: 4b + 2 where b = 1.75 ; then, 4(1.75) + 2 = 7 + 2 = 9
Ron: 8b - 5 where b = 1.75; then, 8(1.75) -5 = 14 - 5 = 9

When you do 288 divided by 30 long division what's the remainder

Answers

$(288)/(30) = (6* 48)/(6* 5) = (48)/(5) = (45+3)/(5) = (45)/(5) +(3)/(5) = 9+(3)/(5) = \boxed{\bf{9(3)/(5)}}$

The divisor is 30.
The dividend is 288.
The quotient is 9.
The remainder is 3.

The remainder is 3.
