Which property is illustrated by the following ?
a = 42, then 6a = 252
The required property for the given statement is multiplication property of equality.
Given:
The given statement is "if [tex]a=42[/tex], then [tex]6a=252[/tex]".
To find:
The property for the given statement.
Solution:
Multiplication property of equality: Let [tex]a,b,c[/tex] are real numbers.
If [tex]a=b[/tex], then [tex]ac=bc[/tex].
We have,
[tex]a=42[/tex]
Using the multiplication property of equality, multiplying both sides by 6.

Trey wrote a few steps to describe how carbon circulates between the atmosphere and living organisms. Step 1. Carbon enters the atmosphere as carbon dioxide from respiration and the burning of fossil fuels. Step 2. Plants absorb carbon dioxide in the air and use it to make their own food using photosynthesis. Step 3. Plant-eating animals consume the carbon stored in plants. If step 2 is removed, which statement best describes the effects of this missing step on the carbon cycle?
Answer:
Dead animals are buried and form fossil fuels, which produce carbon dioxide when burned.
When animals and plants are fossilized and buried under sediments, the higher pressure and temperatures turns them to oil, over time, that is mined and combusted for energy by humans. This plays a significant role in the carbon cycle.
The best statement describing the effects of missing step 2 in Trey's description of the circulation of carbon between the atmosphere and living organisms is: there will be too much carbon dioxide in the atmosphere.
Carbon dioxide in the atmosphere is mostly used by plants to create their food through the well-known process of photosynthesis.
Without step 2, carbon dioxide will not be absorbed by plants through photosynthesis. Therefore, the amount of carbon dioxide present in the air will be too much for other living things and animals. The side effects include:
increase in global warming unsavory increase in ozone depletion worsening global environmental disasterslack of fossil fuel.
Thus, step 2 is an indispensable, necessary, important, and life-saving process in the carbon cycle.

Help me quick!! A rancher has a field in the shape of the polygon shown.
9514 1404 393
Answer:
18 sheep
Step-by-step explanation:
The triangle cut from the upper right corner has a height of 200-100=100 m and a width of 200-120=80 m. Its area is given by the triangle area formula ...
A = 1/2bh
A = 1/2(80 m)(100 m) = 4000 m²
__
The area of the square that includes that triangle is ...
A = LW
A = (200 m)(200 m) = 40000 m²
So, the area of the field where the farmer can keep sheep is ...
field area = 40000 m² -4000 m² = 36000 m²
At 2000 m² per sheep, the field will support ...
(36000 m²)/(2000 m²/sheep) = 18 sheep

What is the length of AC⎯⎯⎯⎯⎯?
The length of AC in the given triangle ABC as per the given condition is equal to 4 units.
To find the length of side AC (opposite angle BAC and BCA) in triangle ABC,
Use the triangle's angle-side-angle (ASA) property.
Side length of AB = x + 4,
Side length of BC = 3x - 8,
Side length of AC = x,
and m∠BAC = m∠BCA.
First, let's write down the ASA property:
If in two triangles, two angles and the included side of one triangle are equal to two angles and the included side of the other triangle,
Then the two triangles are congruent.
Here, angle BAC and angle BCA are equal, and their included side AC is common to both triangles.
So, set up the equation,
x + 4 = 3x - 8
Now, solve for x:
This implies,
⇒3x - x = 4 + 8
⇒ 2x = 12
Divide both the side by 2 we get,
⇒ 2x / 2 = 12/2
⇒ x = 6
Now that found the value of x, find the length of AC:
AC = x = 4
Therefore, the length of AC is 4 units.

The manager of a store that specializes in selling tea decides to experiment with a new blend. She will mix some Earl Grey tea that sells for $6 per pound with some Orange Pekoe tea that sells for $4 per pound to get 400 pounds of the new blend. The selling price of the new blend is to be $4.50 per pound, and there is to be no difference in revenue from selling the new blend versus selling the other types. How many pounds of the Earl Grey tea and Orange Pekoe tea are required?
The blend should have _ pounds of Earl Grey and _ pounds of Orange Pekoe.
9514 1404 393
Answer:
100 pounds Earl Grey300 pounds Orange PekoeStep-by-step explanation:
Let x represent the number of pounds of Earl Gray tea in the mix. Then the total cost of the mix is ...
6x +4(400-x)=4.50(400)
2x +1600 = 1800 . . . . . . . simplify
2x = 200 . . . . . . . . . . . subtract 1600
x = 100 . . . . . . . . . . . divide by 2. Pounds of Earl Grey
(400 -x) = 300 . . . . . Pounds of Orange Pekoe
The blend should have 100 pounds of Earl Grey and 300 pounds of Orange Pekoe.
_____
Additional comment
It is easy to show that the relationship between the quantities of high-cost (H) and low-cost (L) items in the mix (M) is ...
fraction of mix that is H is (M -L)/(H -L)
Here, we have H=6, L=4, M=4.5, so the fraction of the mix that is Earl Grey is ...
(4.5 -4)/(6 -4) = 0.5/2 = 0.25
There are 400 pounds of mix, so 0.25(400) = 100 pounds is Earl Grey.
The solution above is essentially 2-step, so using this relation doesn't necessarily save any steps. It just makes it possible to solve the problem in your head.
Given n(J) = 285, n(K) = 197 and n(J ∪ K) = 431, find n(J ∩ K).
By the inclusion/exclusion principle,
n(J ∩ K) = n(J) + n(K) - n(J U K)
n(J ∩ K) = 285 + 197 - 431
n(J ∩ K) = 51

A two observations
B using previously-proven theorems to show that two cats living together will have yellow eyes.
C showing that all cats with yellow eyes live together

A: two observations.
The rest would prove for definite but due to the lack of observations (one case, two observation) this allows us to disprove (most likely) this conclusion.

The volume of water in a vase is proportional to the depth
of the water. When there are 63 mL of water in the vase,
the depth is 7 cm. How much water is in the vase when
the depth is 9 cm?
A: 49 mL
B: 810 mL
C: 108 mL
D: 81 mL
Step-by-step explanation:
[tex]\frac{63}{7}=\frac{l}{9}[/tex]
[tex]l=81\text{ ml}[/tex]
Answer:
D
Step-by-step explanation:
We are given that the volume of water in a vase is proportional to the depth of the water. In other words, we can write that:
[tex]\displaystyle V = kd[/tex]
Where V is the volume, d is the depth of the water, and k is the constant of proportionality.
When there are 63 mL of water in the vase, the depth is 7 cm. Hence, V = 63 when d = 7:
[tex]\displaystyle (63) = k(7)[/tex]
Solve for k:
[tex]\displaystyle k = \frac{63}{7} = 9[/tex]
Hence, our equation is:
[tex]V = 9d[/tex]
Then when the depth of the vase is 9 cm:
[tex]\displaystyle V = 9(9) = 81\text{ mL}[/tex]
There will be 81 mL of water in the vase.
Hence, our answer is D.
