Answer: 1380 g
Step-by-step explanation: volume of cube is 8 ·8 · 8 cm³ = 512 cm³.
Weight m = density × volume = 2.7 g/cm³ x 512 cm³= 1382.4 g
use mathematical induction to prove the statement is true for all positive integers n. 6 + 12 + 18 + ... + 6n = 3n(n + 1)
Answer:
Step-by-step explanation:
6+12+18+....6n=3n(n+1)
Proof by induction
True for n = 1
6 = 3(1)(1+1)
Assume true for n = k
6+12+18+....6k=3k(k+1)
Then show that
6+12+18+....6(k+1)= 3(k+1)(k+1+1)
We add 6(k+1) to both sides of
6+12+18+....6k=3k(k+1)
6+12+18+....6k +6(k+1) =3k(k+1) + 6(k+1)
= 3(k+1)(k + 2)
= 3(k+1)(k+1+1)
So true for n = k+1
Since true for n=1 it is true for n=2,3,...
Thus true for all natural numbers n by mathematical induction

Jenny left her house at 8:00 AM and went to school at a speed of 2 2/3 mph her brother Jim left the house 4 minutes later and went to the same school. What must his speed be if he wants to keep the same distance between his sister and himself?
Answer:
2 and 2/3 mph
Step-by-step explanation:
The computation of the speed when he wants to keep the same distance is shown below:
Given that
Jenny left her house at 8:00AM
Went for a school at a speed of 2 and 2/3 mph
And, her brother left the house minutes later
So here the speed would be the same i.e. 2 and 2/3 mph

Step-by-step explanation:
Hello There!
The shown figure is a trapezoid with the following dimensions:
Height - 11m
Base 1 - 41m
Base 2 - 19m
Given this information we need to find the area
Remember the formula for the area of a trapezoid is
[tex]A=\frac{a+b}{2} h[/tex]
where a and b are bases and h is the height
Because we are given all of the information needed to calculate the area all we have to do is plug in the values into the formula
So...
[tex]A=\frac{19+41}{2} 11\\19+41=60\\\frac{60}{2} =30\\30*11=330\\A=330[/tex]
In conclusion the area of the figure is 330 square units

Answer:
C x>3
Step-by-step explanation:
Answer:
The answer is (C) x>3
Step-by-step explanation:
Well first just solve it normally like an equation, ignore the sign for now.
-5x+20<5
Isolate the x so we subtract 20 on both sides
-5x<-15
Now divide by -5 to isolate 5 from X
x>3
You switch the sign because whenever you divide or multiply a negative number to isolate x, the sign reverses.
You want to frost a 13 in. by 9 in. cake that you just baked when you notice your little brother ate a piece right out of the middle. What area of cake is left to be frosted if he ate a 2 in. by 2 in. piece? no links pls :) thanks will give brainliest
Answer:
113 inches
Step-by-step explanation:
13 times 9 is 117 inches (this is the area for the whole cake)
2 times 2 is 4 (this is just the middle)
But since the brother ate the middle you will have to subtract the area of the middle piece from the whole area.
117-4 is 113 so the area now is 113 inches

Answer:
x=2
Step-by-step explanation:
1. AB=AC (The triangle is isosceles. This means that at least two of its sides are equal in length. Looking at the triangle in the picture, sides AB and AC look the same, so we will assume that they are equal. Note that as you get more advanced, assuming isn't the best strategy. You should always try to look for hints if you are ever unsure. For example, if there are two angles that are the same measure in a triangle, the two sides that are only touching one of these angles are equal in length. This is called the base angles theorem converse.)
2. 9x-3=6x+3 (Rewrite sides AB and AC as the values given in the picture. This is called substitution.)
3. 9x=6x+6 (Add 3 to each side)
4. 3x=6 (Subtract 6x from each side)
5. x=2 (Divide each side by 3)

Answer:
B.) y - 6 = -8/5(x + 2)
Step-by-step explanation:
Remember in order to find the slope intercept form on 2 points, you need these equations: [tex]\frac{x_2 -x_1}{y_2 -y_1}[/tex] and [tex]y-y_1=m(x-x_1)[/tex]
To find the slope, you will need to use the first equation. In this case the equation will look like this: [tex]\frac{(-2)-6}{3-(-2)}=-\frac{8}{5}[/tex]
Then use the second equation, plug in the numbers, and you will get B as your answer

Answer:
y = 10
x = 17
Step-by-step explanation:
4y - 3 = 37
4y = 37 + 3
4y = 40
y = 40 / 4
y = 10
3x - 9 = 42
3x = 42 + 9
3x = 51
x = 51 / 3
x = 17
Hope that helps!
Answer:
x = 17
y = 10
Step-by-step explanation:
Parallel sides are equal in length, so set them equal to each other.
3x - 9 = 42 --> Add 9 to both sides.
3x = 51 --> Divide both sides by 3.
x = 17
4y - 3 = 37 --> Add 3 to both sides.
4y = 40 --> Divide both sides by 4.
y = 10

The afternoon crew at Yummy Yummy Subbys can make a submarine sandwich once every 45 seconds. The evening crew can only make a submarine sandwich once every 50 seconds. If both crews work together, how many seconds will it take them to make 38 submarine sandwiches?
Answer: 900
Step-by-step explanation:
The number of seconds it will take both the crew together to make 38 sandwiches is 900.
What is LCM?The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.
The time taken by the afternoon crew to make a sandwich is 45 seconds. The time taken by the evening crew to make a sandwich is 50 seconds. Taking the LCM of the timing of the two crew, to know at what time they both will finish making a sandwich together.
LCM of 45 and 50 is 450.
Therefore, the number of sandwiches made by the afternoon crew in 450 seconds is 10, while the number of sandwiches that will be made by the evening crew is 9. Thus, in a time period of 450 seconds, both crews together will make 19 sandwiches.
Now, since it takes 450 seconds to make 19 sandwiches the time it will take to make double the number of sandwiches therefore, 38 sandwiches will also be double.
Hence, the number of seconds it will take both the crew together to make 38 sandwiches is 900.
