One number is 9 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 848, find the numbers
The three numbers are needed
Answer:
[tex]first \: no \: 9x \\ second \: numberx \\ third \: no9x + 100 \\ 9x + x + 9x + 100 = 848 \\ 19x + 100 = 848 \\ 19x = 848 - 100 \\ \\ 19x = 748 \\ \\ x = 39.4[/tex]
Step-by-step explanation:
9×+×+100+9×=848
19×+100=848
19×=848-100
19×=748
×=39.4
9×=354.6
9×+100=354.6+100=454.6

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.

Find the distance between X (-3,8) and Z (-5,1). Round to the nearest tenth if necessary.
9514 1404 393
Answer:
7.3
Step-by-step explanation:
The distance formula is used for this purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-5-(-3))² +(1 -8)²) = √((-2)² +(-7)²) = √(4+49) = √53
d ≈ 7.28011 ≈ 7.3 . . . units
XZ ≈ 7.3

4+ |2-3x| =7
solve for all values of x in simplest form
Answer:
x = 1/12
1/12 = 0.833
Step-by-step explanation:
to find the value of x
4+ |2-3x| =7
8 - 12x = 7
-12x = 7-8
-12x = -1
x = 1/12
if we write 1/12 in simplest form so
1/12 = 0.833

Answer:
Number one is only a function
Step-by-step explanation:
A function has all different x values, but if there are two of the same x values with different y values, that is not a function. It’s okay if there are two do the same x values- they just have to have the same y values.
Number one has all different x values
Number two has an x value with two different y values, therefore it is not a function
Number 3 has two of the same x values but with different y values, so it’s not a function
Number four is not a function because of the vertical line test. You pick a point on the line and draw a vertical line all the way through the line. If that point passes through any other points, that it is not a function. Number four doesn’t pass the vertical line test, so it’s not a function.

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.
[tex]6\cdot a=6\cdot 42[/tex]
On simplification, we get
[tex]6a=252[/tex]
Therefore, the required property for the given statement is multiplication property of equality.

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.
