Answer:
40.5
Step-by-step explanation:
diameter^2 = (3 +6)^2 + (5+4)^2
or, d^2 = 9^2 + 9^2
or, d^2 = 81 +81
or,d^2 =162
or d=√ 162
• d= 81
then radius = d/2
r = 81/2
•r= 40.5 ans

Step-by-step explanation:
X always comes first in ordered pairs
<h3>Answer: Choice B)
</h3>
===========================
Explanation:
n = first number
n+2 = second number
Consecutive odd integers are odd numbers that follow one after another. Eg: {3, 5, 7, 9}
Note how I add 2 each time to get the next number. So that explains the "n+2"
Add up n and n+2, then set that sum equal to or larger than 84 like so
We could simplify or solve for n, but I'll stop here since this is what answer choice B is saying.
side note: "at least" means "that value or more". So if I said "at least 10", then I mean "10 or more".
<u><em>Answer:</em></u>
Density of jam = 11.35 kg/m³
<u><em>Explanation:</em></u>
<u>1- Getting the mass of the jam:</u>
<u>We are given that:</u>
Jam is put in 6 jars
the weight of one empty jar = 200 grams
<u>Therefore: </u>
weight of 6 empty jars = 6 * 200 = 1200 grams
<u>We are also given that:</u>
Weight of all jars filled with jam is 5400 grams
<u>Therefore:</u>
mass of jam = total mass of jam and jars - mass of 6 empty jars
mass of jam = 5400 - 1200
mass of jam = 4200 grams
<u>2- Getting the volume of the jam:</u>
We are given that the 6 jars had a total volume of 0.37 m³ and that they were completely filled with jam
<u>This means that:</u>
Volume of jam = 0.37 m³
<u>3- Getting the density of jam:</u>
<u>Density can be calculated using the following rule:</u>
<u>We have:</u>
Mass of jam = 4200 grams = 4.2 Kg
Volume of jam = 0.37 m³
<u>Therefore:</u>
Hope this helps :)
