It’s really simple once you know how to solve. I’ll use problem c to show you how.

Multiply by the reciprocal. (Just flip 3/4 upside down and change the sign)

5/8 x 4/3

Multiply:

20/24

Simplify:

5/6 (answer to c)

Let me know if this helped. I can help with the other problems if you need it!

PLEASE HELPPPPPP!!!!! You are performing an experiment to determine how well plants grow under different light sources. Of the 3
PIT_PIT [208]

The probability that a plant in the experiment receives visible or ultraviolet light is 7/10.

<u>Step-by-step explanation</u>:

The total number of plants in the experiment = 30 plants

Plants that receive visible light alone = 12 plants

Plants that receive ultraviolet light alone = 15 plants

Plants that receive both visible and ultraviolet light = 6 plants

<u>step 1</u> :

<em>Probability = No. of required events / Total number</em>

<u>step 2</u> :

P(visible) = 12 / 30

P(ultraviolet) = 15 / 30

P(both) = 6 / 30

<u>step 3</u> :

P(visible  or ultraviolet) = P(visible)  + P(ultraviolet) - P(both)

                                         = 12/30 + 15/30 - 6/30

                                         = 21/30

P(visible  or ultraviolet) = 7/10

here are 3 red candies in a pack, 6 blue candies in a pack, and 14 pink candies in a pack. If your wonderful math teacher wants
Naily [24]
Given:
3 red candies
6 blue candies
14 pink candies

Condition:
Split into bags where candies have an equal number of red, blue, and pink candies.

There can only be 3 bags. Each containing 1 red candy, 2 blue candies, and 4 pink candies. There will be an excess of 2 pink candies. 

This division is solely reliant on the number of red candies available because it is the color that has the smallest number of candies.

Jessica received a 90$ gift card for a coffee store. She used it in buying some coffee that cost 8.58per pound. After buying the
irga5000 [103]

Answer:

5 pounds / Make sure to read the explanation so you know how to solve it

Step-by-step explanation:

First thing to do is:

Subtract 90 by 47.10 to find the amount of money she spent

90 - 47.10 = 42.90

She spent $42.90 on coffee and we know that it costs $8.58 per pound so that means that we should divide 42.90 by the cost per pound:

42.90 / 8.58 = 5

She bought 5 pounds of coffee

Hope I helped :]
