Answer:
<h3>29 and 32</h3>
Step-by-step explanation:
Let x = number
Let y = second number
We know that there are two true equations from this. Here is shown below the equations.
x + y = 61
x + 3 = y
We could use the substitution method for finding the numbers. After that, we continue on to solve to find the first number.
x + (x+3) = 61
2x + 3 = 61
2x = 58
2x/2 = 58/2
x = 29
Now that we know that the first number is 29, plug it in to the second equation to find the second number.
x + 3 = y
29 + 3 = y
y = 32
Proof that these numbers are the correct answer:
32 + 29 = 61
61 = 61 (Which is true!)
To support me, please give me the brainliest answer. It would be greatly appreciated. Thank you!
Answer:
<h2><u><em>
90</em></u></h2>
Step-by-step explanation:
1000 + 500 = 1500mg (for 1 day)
1500 * 30 = 4500mg (1 month)
4500 : 500 = 90 tablets
<h3>
Answer: 15</h3>
===============================================
Explanation:
Extend the given line out as far as you can. I have done so using a red line in the attached image below.
Then move to "3" on the horizontal x axis. Draw a line straight up until you hit the red line. I use a green arrow to show this. You'll hit the blue point on the diagram. From there, move horizontally until you hit the y axis. You should land on y = 15. This shows the blue points coordinates are (3, 15)
x = 3 means three boxes contain a total of y = 15 chocolates.
note: the slope is 5 which represents the amount of chocolates in one box.
Cos θ = adjacent / hypothenus = 5/13
opposite = sqrt(hypothenus^2 - adjacent^2) = sqrt(13^2 - 5^2) = sqrt(169 - 25) = sqrt(144) = 12
sec θ = 1/cos θ = 1/(adjacent / hypothenus) = hypothenus / adjacent = 13/5
cot θ = 1/tan θ = 1/(opposite/adjacent) = adjacent / opposite = 5/12
sec θ = 13/5
cot θ = 5/12
289 196 248 379 319 276 198 349
(in order) 196, 198, 248, 276, 289, 319, 349, 379 there are eight numbers.
--------------------------------------------------------------------------------------
196, 198, 248, 276
since the median is between 198 and 248, we must add both numbers together and divide them by two:
(198 + 248) ÷ 2
= 446/2
<h2>
= 223 (first quartile)</h2>
--------------------------------------------------------------------------------------
289, 319, 349, 379
since the median is between 319 and 349, we must add both numbers together and divide them by two:
(319 + 349) ÷ 2
= 668/2
<h2>
= 334 (third quartile)</h2>
--------------------------------------------------------------------------------------
Interquartile range:
<h2>
IQR: 334 - 223 = 111 </h2>
