What is the name of the common ancestor of the bobcat and the cheetah?

Nookie1986 [14]

The sample columns have two missing layers as follows:

Column 1: Layers 3 and 8 are missing.
Column 2: Layers 1 and 7 are missing.
Column 3: Layers 1 and 5 are missing.

<h3>What is geology? </h3>

Geology is a term to refer to the specialized science that focuses on the study of the composition and internal and external structure of the surface of the planet Earth, and the processes by which it has evolved throughout geological time.

In the image 3 columns are shown showing various layers of the Earth, however, each of it has 2 missing layers. To know which layers were missing from each one, we must analyze them to establish what a column with complete layers would look like and then compare the 3 samples with the model to know which layers are missing.

According to the previous process, it can be inferred that the missing layers in each column are:

Column 1: Layers 3 and 8 are missing.
Column 2: Layers 1 and 7 are missing.
Column 3: Layers 1 and 5 are missing.

Note: This question is incomplete because the graph is missing. Here is the graph.

Bob, a nutritionist who works for the university medical center, has been asked to prepare special diets for two patients, susan

abruzzese [7]

Answer and Explanation:

Possibly, you forgot to attach the table with the contents of each food. Therefore, I calculated the task with similar values.

1. Assume you have Food A, B, and C. Each has certain amount of Calcium, Iron, and Vit C.

Let's designate: Calcium → X oz , Iron → Y oz, vit C → Z oz

2. Assume you have following amount of Calcium in each food:

Food A = 30 mg/oz
Food B = 25 mg/oz
Food C = 20 mg/oz

3. Assume you have following amount of Iron in each food:

Food A = 1 mg/oz
Food B = 1 mg/oz
Food C = 2 mg/oz

4. Assume you have following amount of vit C in each food:

Food A = 2 mg/oz
Food B = 5 mg/oz
Food C = 4 mg/oz

Calculations:

→ You have 3 different food and each has Calcium in it. You need exactly 320mg of Calcium per day. Therefore, each food would comprise certain proportion of daily Calcium intake. We can come up with equation: 30X+25Y+20Z = 390 mg

Similarly, for iron and vitamin C, the next equations could be used:

X+Y+2Z=17 - Iron

2X+5Y+4Z=42 - Vit C

→ Now you have a system of equations:

30X+25Y+20Z = 390 (1)

X+Y+2Z=17 (2)

2X+5Y+4Z=42 (3)

→ Look for similarities! (1) and (3) seem to be similar. We can multiply the (3) by -5 to obtain: -10X-25Y-20Z=-210. We add the (1) and modified (3) equations.

30X+25Y+20Z = 390

-10X-25Y-20Z=-210

__________________

20X+0+0=180

20X=180

→ X=9 (oz of Calcium)

→ Now, we can put x=9 into equations above to ease our job:

270+25Y+20Z=390 → 25Y+20Z=390-270=120

9+Y+Z=17 → Y+2Z=17-9=8

18+5Y+4Z=42 → 5Y+4Z=42-18=24

→ Similarly, we can use Eq-s (2) and (3). We can multiply the (2) by -5 to obtain: -5Y-10Z=-40. We add the (3) and modified (2) equations.

-5Y-10Z=-40

5Y+4Z=24

__________________

-6Z=-24

Z=4

→ Z=4 (oz of vit C)

→ Now, we can take X+Y+Z=17 (2) and just put in known values(X=9 and Z=4) to obtain Y:

9+Y+4=17

→ Y=17-9-4=4 (oz of Iron)

That's all! So, if you have table values, you can just re-write the equations and doing it stepwise, as it is shown here, you can manage to calculate every value you need :)
