Answer:

  9, the sum of the numbers given in the ratio

Step-by-step explanation:

The reduced ratio 2 : 7 means that two parts correspond to one length and 7 parts correspond to the other length. That is, there are a total of 2+7 = 9 parts in the full length of the segment.

It is convenient to think of the line segment as being divided into 9 equal parts.

_____

Additional comments

It is often helpful to consider the total number of "ratio units" in a given ratio. For example, in this problem, the shorter segment is 2/9 of the whole, and the longer one is 7/9 of the whole.

It can also be useful to consider what a "ratio unit" represents. If the whole segment is 27 inches long, then each of the 9 ratio units will represent 3 inches, for example. This means the division 2:7 is 2(3 in):7(3 in) = 6 in : 21 in.

Answer: 72 ft

Step-by-step explanation:

Given

The width of a post is [tex]w=6\ in.[/tex]

Posts are separated by [tex]5\ ft[/tex] chain

for 2 posts, length is [tex]6+5+6=17\ ft[/tex]

for 3 posts, length is [tex]6+5+6+5+6=28\ ft[/tex]

for 4 posts, it is [tex]28+5+6=39[/tex]

i.e. 11 ft is adding on the addition of another post

for 7 posts it is [tex]17+11\times 5=72\ ft[/tex]

Thus, the total length of the fence is [tex]72\ ft[/tex]

Answer:

[tex]y = 18 * 1.15^x[/tex]

Step-by-step explanation:

Given

[tex]a = 18[/tex] --- initial

[tex]r =15\%[/tex] -- rate

Value after a year = $20.70

Required

Expression to calculate its value after y years

This is calculated using:

[tex]y = ab^x[/tex]

Where

[tex]b=1 +r[/tex]

Substitute [tex]r =15\%[/tex] in [tex]b=1 +r[/tex]

[tex]b = 1 + 15\%[/tex]

[tex]b = 1 + 0.15[/tex]

[tex]b = 1.15[/tex]

Substitute [tex]b = 1.15[/tex] and [tex]a = 18[/tex] in [tex]y = ab^x[/tex]

[tex]y = 18 * 1.15^x[/tex]

Answer:

H and K in the equations of a circle represents the coordinates of it's center point.

Step-by-step explanation:

The variables h and k represent the coordinates of the center of the circle

In the equations of a circle in standard form, [tex](x - h)^2 + (y - k)^2 = r^2[/tex].

The value of h corresponds to the x-coordinate of the center, while the value of k represents the y-coordinate of the center. The center of the circle is denoted as (h, k).

By specifying the values of h and k, we can determine the exact location of the center of the circle on the coordinate plane. These coordinates help identify the position of the circle in relation to the x and y axes.

For example, if the equation of a circle is [tex](x - 2)^2 + (y + 3)^2 = 16[/tex], the center of the circle is located at the point (2, -3), with h = 2 and k = -3.

Understanding the significance of h and k allows us to identify the center of a circle and provides valuable information for analyzing and graphing circles in the coordinate plane.

Therefore, the variables h and k represent the coordinates of the center of the circle

Answer:

(5,6)

Step-by-step explanation:

Generally, is the coordinate (x,y) is translated right by a units and up by b units, the resulting coordinate wil be;

g(X, Y)  = (x+a, y+b)

To the right is along the positive x axis while up is along the positive y axis

Given a = 3 and b = 4

g(X,Y) = (2 + 3, 2 + 4)

g(X, Y) = (5, 6)

Hence the resulting coordinate of g is (5,6)

Answer:

your answer is A chemical weathering

Step-by-step explanation:

as when volcanic gasses and atmospheric gasses mix it can become a sort of acidic rain in some cases I hope this answer helps I apologize for any wrong answers this is not my best subject but I wanted to attempt this as I k ow a small amount about it!

The process described in the question is known as acid rain, which is a type of chemical weathering. The correct answer would be option (A) chemical weathering.

When atmospheric and volcanic gases mix with water in the atmosphere, they can form acids such as sulfuric acid and nitric acid. These acids can then drop to the earth as acid rain. In rare situations, the mixing of volcanic and atmospheric gases can result in acidic rain.

Acid rain can cause chemical reactions with minerals in rocks and soil, dissolving them over time. This can lead to the breakdown of the rock or soil, which is an example of chemical weathering.

Thus, the process described in the question is known as acid rain, which is a type of chemical weathering.

Hence, the correct answer would be option (A) chemical weathering.

Answer:

They will both blink again at 3:12 pm.

Step-by-step explanation:

As indicated by the question, the way to solve is to find the Lowest (or Least) Common Multiple of both numbers.

As such:

[tex]\text{List the factors of 12 and 44:}\\12=2*2*3\\44=2*2*11\\\\\text{Take the common factors only once and multiply them by the non-common factors:}\\2*2*3*11=132 \text{ (LCM)}[/tex]

Now knowing the LCM is 132, we convert those minutes into hours and minutes:

[tex]\frac{132}{60}=2\frac{12}{60} \text{ (2 hours and 12 minutes)}[/tex]

Add this to the original time:

[tex]1:00\text{ pm } + \text{ }2:12 \text{ }= \text{ }3:12\text{ pm}[/tex]

Answer:

choice 1) 2x + 40 = 180

Step-by-step explanation:

(x + 10) + (x + 30) = 180

2x+ 40 = 180

Answer:

X+30+x+10=180

combine like terms

2x+40=180

subtract 40 from both sides

2x=140

divide by 2

x=70

but for you it is 2x+40=180
