Answer:

3 boxes

Step-by-step explanation:

First, we find how many cubes are in each box, then we find how many boxes you need for 140 cubes.

<u>To find the number of cubes in a box we need to find the volume of the figure</u>

the top is 2 wide and 4 long so there are 8 cubes on each layer. Sense it is 8 cubes tall with 8 cubes on each layer the model has 8×8=64 cubes in each box.

<u>Now we divide then round up to find how many full boxes she needs to get 140 cubes or more.</u>

If 1 box has 64 cubes and she needs 140 cubes 140/64=2.187. Now we round up sense he can't buy a fraction of a box and the answer is: She needs 3 boxes

Identify the equation that translates y=ln(x) five units down.
kari74 [83]

We are given equation: y=ln(x) .

And translation is 5 units down.

We know the rule of transformation f(x) = y + k, if k is greater than 0 it would move up or if k is less than 0, it would move down.

For the given translation 5 unit down, 5 should be less than 0.

Number less than 0 are negative numbers.

So, we need to add -5 in the given function to ln(x).

So, we would get the final equation for five units down as

y =ln(x) - 5.

Kylie jarred 12 liters of jam after 2 days. How many days does Kylie need to spend making
atroni [7]
Since it requires 2 days to jar 12 liters of jam, if we want to find out how many days it takes to jar 48 liters, we divide 48 by 12 and get 4.
Then we multiply 4 by 2 and get 8 days. It took 8 days to fill 48 liters of jam.
12/2 = 48/x

12x = 96

x = 8

Round your answer to the nearest tenth.
Kruka [31]

Answer:

The value of MB = 8.4

Step-by-step explanation:

We know that the point of intersection of the Medians of a triangle is called the centroid of a triangle.

Thus,

For the given triangle ΔJKL,

  • The point M is the centroid of the triangle.

We also know that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.

Also, each Median is split into two parts such that the longer part is 2 times the length of the smaller part.

In our case,

The median KB is split into two parts such that the longer part KM is 2 times the length of the smaller part MB.

i.e.

KM = 2 MB

Given KM = 16.8

so substitute KM = 16.8 in the equation KM = 2 MB

16.8 = 2 MB

MB = 16.8/2

MB = 8.4

Therefore, the value of MB = 8.4
