There are 3 ways to express a ratio, but my favorite is a fraction so my explanation will use those.

Red to blue is 8:10 expressed as a fraction is 8/10 we then can simplify it to 4:5 or 4/5

Black to red would be 3:8 NOT 8:3.

Blue to all is 10:15 or 10/15 which we can simplify to 2/3 or 2:3.

I don’t know about the last one, depends on whether you include the amount of black bikes in the “all ratio” I think it’s correct.

Hope I helped ^u^

An online furniture store sells chairs for $150 each and tables for $400 each. Every day, the store can ship no more than 30 pie
ivolga24 [154]

Answer:

minimum of 13 chairs must be sold to reach a target of $6500

and a max of 20 chairs can be solved.

Step-by-step explanation:

Given that:

Price of chair = $150

Price of table = $400

Let the number of chairs be denoted by c and tables by t,

According to given condition:

t + c = 30 ----------- eq1

t(150) + c(400) = 6500 ------ eq2

Given that:

10 tables were sold so:

t = 10

Putting in eq1

c = 20 (max)

As the minimum target is $6500 so from eq2

10(150) + 400c = 6500

400c = 6500 - 1500

400c = 5000

c = 5000/400

c = 12.5

by rounding off

c = 13

So a minimum of 13 chairs must be sold to reach a target of $6500

i hope it will help you!

Help! I need help with finding the value of x.
Dmitry_Shevchenko [17]

Answer:

x = 18.64

Step-by-step explanation:

use tan:

⇒ tan = \frac{opposite}{adjacent}

⇒ tan 46 = \frac{18}{x}

tan of 46 is 1.0355

⇒ 1.0356 = \frac{18}{x}

multiply 18 on both sides

⇒ 1.0355 x 18 = \frac{18}{x} x 18

⇒ 18.64 = x
