If a 42-inch string is to be cut so that one piece is 7 inches longer than the other, then the shorter piece has a length of 17.5 inches

The length of the shorter piece can be determined by using an algebraic expression.

Any expression consisting of both numbers and letters is considered to be an algebraic expression.

Considering, x to be the length of the shorter piece

As the longer piece is 7 inches longer than the shorter piece, an algebraic expression can be given as,

x + (x + 7) = 42

x + x + 7 = 42

2x + 7 = 42

2x = 42 - 7

2x = 35

x = 35 ÷ 2

x = 17.5

Hence, the length of the shorter piece is calculated to be 17.5 inches.

The function rule after the given transformation is g(x) = -3x

A function is defined as a relation between a set of inputs having one output each.

We have,

f(x) = 9x

Vertical compression = 1/3

Reflection in x-axis.

We know that when we compress a function f(x) by scale factor m

The new compress function is represented:

F(x) = m(f(x))

Reflection across the x-axis changes the sign of the new function.

Now,

With the vertical compression:

F(x) = 1/3 (f(x))

F(x) = 1/3(9x) = 3x

With the reflection in the x-axis:

g(x) = - F(x)

g(x) = -3x

Step-by-step explanation:

a) Imagine folding the net into the shape. In this case, Net A can have both triangles fold up, and both rectangles fold in to make the above shape.

b) Side AB on this net is the height of the triangle, 3 inches.

   Side BC is the same as the hypotenuse (diagonal) on the triangle, which       .   is 5 inches.

   Side CD is the same as the length of the shape, which is 8.6 inches.

c) Surface area = area of all sides

Triangle = 1/2 bh

              = 2*3

              = 6 inches squared

There are two triangles, so that adds to 12 inches squared.

Now all of the rectangles:

Left most = 3*8.6

                = 25.8 inches squared

Middle = 4*8.6

            = 34.4

Right most = 5*8.6

                  = 43

Now we can add all of this:

43 + 34.4 + 25.8 + 12

= 115.2 inches squared.

This is the surface area of the prism.

If two quantities are proportional, the true statements about the graph showing the relationship between them are-

D. The points of the graph form a straight line.

E. The points of the graph must include the origin.

F. The points must all form equivalent ratios.

In mathematics, two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.

Now let us suppose there are two quantities x and y.

A graph between two quantities is plotted.

Suppose x is directly proportional to y.

Thus, these Two variable quantities have a constant ratio

So, we can write

y ∝ x

Applying constant of proportionality,

y = kx

Where k is the constant of proportionality.

It represents a straight line.

Now,the value of x = 0 then the value of y must be equal zero, then the line which represented the direct variation must be passes through the origin

Now  If two variable quantities have a constant ratio and since y = kx is a straight line and passes through origin therefore from the given options the correct answer are-

D. The points of the graph form a straight line.

E. The points of the graph must include the origin.

F. The points must all form equivalent ratios.

Histograms are a very common method of visualizing data, and that means that understanding how to interpret histograms is a valuable and important skill in virtually any career. There are a number of things to pay particular attention to when reading a histogram.

Bell-Shaped: A histogram with a prominent ‘mound’ in the center and similar tapering to the left and right. One indication of this shape is that the data is unimodal – meaning that the data has a single mode, identified by the ‘peak’ of the curve.

Uniform: A uniform-shaped histogram indicates data that is very consistent; the frequency of each class is very similar to that of the others.

Right-Skewed: A right-skewed histogram has a peak that is left of the center and a more gradual tapering to the right side of the graph.

Left-Skewed: A left-skewed histogram has a peak to the right of the center, more gradually tapering to the left side. It is unimodal, with the mode closer to the right and greater than either mean or median.

Undefined Bimodal: This shape is not specifically defined, but we can note regardless that it is bi-modal, having two separate classes or intervals equally representing the maximum frequency of the distribution.

The amount in a continuously compounded account is $ 565.2 .

If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach.

The amount in the continuously compounded account is given as:

[tex]A=Pe^{rt}[/tex]

Where P is the principal amount, r is the interest rate, and t is the time period in years.

Now, we have

The principal amount, P = $500

Colin pays $95.36 more monthly than he would annually.

Colin pays (to the nearest percent) 8.99 % more by paying monthly premium than he would paying annually.

Premium is the amount of money one has to pay to insurance companies so that they provide us coverage at the time of need.

If we make payments monthly, the the premium is monthly.

If we pay the amount at the end of the year, then the premium is annual.

Given that Edmond has a $60,000 term life policy. The annual premium is $1,060. Colin pays $96.28 monthly.

Monthly premium of Edmond = $96.28

If he pays monthly, then total payment at the end of 12 months

= 12 *$96.28 = $1155.36

Then total payment at the end of 12 months is greater than the annual premium by = 1,156.36 - 1,060 = 95.36

Percentage of extra amount paid  when colin paid monthly

    = (extra payment made/ annual payment ) *100 = (95.36/1,060)*100             =8.99 %

Using the law of cosines, the measures of the angles are given as follows:

The law of cosines states that we can find one of the sides or the angle C of a triangle according to the following equation:

c² = a² + b² - 2abcos(C)

In which:

For this problem, the parameters for the triangle are given as follows:

a = b = 12, c = 3.

We want to solve for the smallest angle C, hence:

c² = a² + b² - 2abcos(C)

9 = 288 - 288cos(C)

288cos(C) = 279

cos(C) = 279/288

C = arccos(279/288)

C = 14.36º.

The other two angles are congruent, and the sum of the internal angles of a triangle is of 180º, hence:

14.36 + x + x = 180

the common number of 4 and 8 is 8. You multiply 1/4 by 2 and it is equal to 2/8. 2/8+ 5/8= 7/8. 8-7=1. 1/8 of the houses are gray.

Reason:

The counting numbers, aka the set of natural numbers, is the set {1, 2, 3, 4, 5, ...} which is the set of positive integers

A value like 5 is the same as 5/1, which shows it is rational.

A rational number is any fraction of two whole numbers (eg: 2/3 and 4/7). The denominator cannot be zero.

Since we can rewrite the 5 as 5/1, it can be done with any counting number to show the natural numbers is a subset of the rational numbers.

Any counting number is rational, but not the other way around.

Answer:

[tex]y = \frac{3}{4}x - 8[/tex]

Step-by-step explanation:

We know that the slope of a line perpendicular to a line with a given slope is the negative reciprocal of that given slope.  We are given that we want a line perpendicular to that of 4x + 3y = 3.  To find the slope of this given line, we put it into slope intercept form y = mx + b where m is the slope:

[tex]4x + 3y = 3[/tex]

[tex]3y = 3 - 4x[/tex]

[tex]y = 1 - \frac{4}{3}x[/tex]

So we have that the slope of our given line is -4/3. The negative reciprocal of this is 3/4. We thus have that the slope of the line we are looking for is 3/4.

We then know that the equation of the line we want fits the form [tex]y=\frac{3}{4} x + b[/tex], which we know through point slope form. We are then given that (8, -2) is a point on this line. Plugging in:

[tex]-2 = \frac{3}{4}(8) + b[/tex]

[tex]-2 = 6 + b[/tex]

[tex]b = -8[/tex]

We then get the equation of the line we are looking for as [tex]y = \frac{3}{4}x - 8[/tex].

Let x represent the ticket for a crab meal and y represent the ticket for a vegetarian meal

From the given information,

"One troop member sold tickets for 23 crab meals and 34 vegetarian meals, with total receipts of $1,930"

That is,

23x + 34y = 1930            -------------- (1)

Also,

"Another sold tickets for 20 crab meals and 38 vegetarian meals, bringing in a total of $1,906"

20x + 38y = 1906           -------------- (2)

Now, solve the equations simultaneously

Multiply equation (1) 20 and equation (2) by 23

20 × [23x + 34y = 1930

23 × [20x + 38y = 1906

460x + 680y = 38600

460x + 874y = 43838

Subtracting the resulting equations, we get

-194y = -5238

y = -5238/-194

y = 27

Substitute the value of y into equation (1)

23x + 34y = 1930

23x + 34(27) = 1930

23x + 918 = 1930

23x = 1930 - 918

23x = 1012
