A copy machine makes 36 copies in a minute (1).
Multiply 36 copies by 3.75 (3 min and 45 sec) to find how many copies it can make within that time.
(36)(3.75) = 135
The copy machine can make 135 copies in 3 minutes and 45 seconds.
Answer:
$420
Step-by-step explanation:
130x12=1560
165x12=1980
1980-1560=420
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
Answer:
B. They must bisect each other
Step-by-step explanation:
Found the answer on quizziz
A^2 + B^2 = C^2.
so 49 + 576 = C^2
625 = C^2
Now find the square root of 625.
25 = C (in your case r)
