6 0

Step-by-step explanation:

1. Ratio(White to black) = 12 / [52 - 12]

Ratio(White to black) = 12 / [40]

Ratio(White to black) = 3 / 10 = 3:10

2. Ratio(Blue triangle to all) = 5 / [5+80]

Ratio(Blue triangle to all) = 5 / [85]

Ratio(Blue triangle to all) = 1 / 17 = 1:17

3. Ratio(Circle to all) = 76 / [22+76]

Ratio(Blue triangle to all) = 76 / [98]

Ratio(Blue triangle to all) = 38 / 49 = 38:49

4. Ratio(Yellow triangle to blue) = 18 / 14

Ratio(Yellow triangle to blue) = 9 / 7 = 9:7

5. Ratio(Yellow triangle to blue) = 42 / 6

Ratio(Yellow triangle to blue) = 7 / 1 = 7:1

6.Ratio(Boys to all) = 63 / [27 + 63]

Ratio(Boys to all) = 63 / 90

Ratio(Boys to all) = 7 / 9 = 7:9

ryan can build 4 desks in one day and larry can build 4 desks in 2 days. if larry starts work one day before ryan, how long will
MissTica
You can make an equation with this information using a variable for the number of days and solve for that variable. Here we can use d to represent days.

Ryan can build 4 desks in a day, so you could express his production as 4d.

Larry can build 4 desks in 2 days, so you could say he makes 2 desks in 1 day, expressed as 2d.

If Larry starts work one day before Ryan, he's made an extra 2 desks. To get 32 desks, you need to add together those 2 desks Larry made, however many desks Larry can make, and however many desks Ryan can make:

2 + 4d + 2d = 32.

Then just simplify and solve:

6d = 30
d = 5.

It'll take 5 days for them to make 32 desks. Hope this helps! Please rate this answer as brainliest if you liked it!! thank you!!!
