16 cups of water using 1/2 cup of measuring cup will fill a gallon of water.

To find the number of 1/2 cups that will fill a gallon, we simply need to know how many cups are in one gallon.

[tex]1cup = 0.0625 gallon[/tex]

This implies that

[tex]\frac{1}{2} cup = 0.03125 gallon[/tex]

Let's equate this and find how many cups are in one gallon.

[tex]\frac{1}{2} cup = 0.03125 gallon\\x cup = 1 gallon\\[/tex]

cross multiply both sides and make x the subject of formula

[tex]x = \frac{0.5}{0.03125}\\x = 16 cups[/tex]

The number of 1/2 cups that will fill 1 gallon will be 16 cups.

Solution of the given algebraic expression (f-g)(x) is equal to 4x³+6x²-7x-1

Algebraic equations are defined as mathematical statements in which two algebraic expressions are set equal to each other. An algebraic expression usually consists of  variables,  coefficients and  constants. Algebraic equations can be of many types, such as monomial algebraic equations, binomial algebraic equations, quadratic algebraic equations, polynomial equations.  

Given in the question that the value of f(x) is equal to 4x³+6x²-3x-4

and the value of g(x) is equal to 4x-3.

Subtracting g(x) from f(x) we get,

(f-g)(x)= 4x³+6x²-3x-4-4x+3

4x³+6x²-7x-1

The actual closet has a length of 6 feet

The scale of the drawing is given as

Scale = 8 inches : 3 feet.

Also, we have the length of the closet to be

Length = 16 inches

So, we have

16 inches : Actual length = 8 inches : 3 feet.

Multiply the ratio by 2

So, we have

16 inches : Actual length = 16 inches : 6 feet.

By comparison, we have

Actual length = 6 feet

Hence, the length of the actual closet is 6 feet

From the information, Rowena buys cashmere wool in 20g balls. Each ball of cashmere wool costs her £1.42 and she pays her sister £8 to knit each pair of socks. The cost will be:

= (£1.42 × (20 + 135) + (40 × £8)

= £220.1 + £320

= £540.1

The selling price will be:

= £18.95 × 40

= £758

Therefore, the percentage profit will be:

= Profit / Cost price × 100

= (758 - 540.1) / 540.1 × 100

Parallel lines are coplanar straight lines that do not intersect at any point in geometry. Parallel planes are planes that never meet in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance.

Parallels, paralleling, and paralleled are all word forms. a countable noun A parallel is something that is similar to something else but exists or occurs in a different place or at a different time.

Parallel lines are lines that are always the same distance apart in a plane. Parallel lines never cross. Perpendicular lines are those that intersect at a right angle (90 degrees).

Two different interior angles.

Leah can run 320 yards in 2 minutes at the same rate as she can run 720 yards in 4.5 minutes. The correct option is B. 320.

To find out how many yards Leah can run in 2 minutes at the same rate, we can use the concept of proportionality.

Let's set up a proportion based on the information given:

720 yards / 4.5 minutes = x yards / 2 minutes

To find the value of x, we can cross-multiply:

4.5 minutes × x yards = 720 yards × 2 minutes

Now, divide both sides by 4.5 to solve for x:

x yards = (720 yards × 2 minutes) / 4.5 minutes

x yards = 320 yards

So, Leah can run 320 yards in 2 minutes at the same rate.

The correct answer is B. 320.

We have to find ow many transistors could fit on a microchip [tex]19[/tex] years later.

From the question total years are [tex]19[/tex].

Since the number of transistors is increased every year so number of transistors of previous year added. So we can see that  the number of transistors that can be fit on a microchip is increased compound. We can find the total number of transistors by multiplying number of transistors with the rate assembled by one. So we can use the formula

So the number of transistors could fit on a microchip 19 years later.

Number of transistor = Microchips from a given year could hold about transistors(1 + increment rate)^total years

Number of transistor [tex]=922,200(1+\frac{40}{100})^{19}[/tex]

The covariance value between two variables says, days to 230 lbs and backfat thickness, is 0.48..

The covariance value between any two variables is used to determine whether the variables are changing in the same direction. It relates the two variables if they are from different data sets.

Let X and Y be two data sets with different values. Then the covariance between X and Y is given by

Cov ( X,Y) = ∑ ( X ᵢ– u) ( Yⱼ-v ) /n

Where are Xᵢ's elements in the X data set

Yⱼ→ elements of the Y set

μ → mean of X data set

ν→ mean of Y set

n→ total number of observations

As we have given two sets of data, let days to 230 lbs and backfat thickness be sets X and Y, respectively.

Now, we shall calculate the mean value for X and Y sets.

Mean of X set = (164+158+180 + +160+198+172+186+178+178+186)/10= 176

The mean of Y set =

 (1.0+ 1.1+ 1.2+ 1.4+1.2+1.3++1.1+1.3+1.4+1.0)/10 = 1.2

Xᵢ– μ - 12 -18 4 -16 22 -4 10 2 2 10

Yⱼ– ν -.2 - .1 0 .2 0 .1 -.1 .1 .2 -.2

(Xᵢ - μ)(Yⱼ- ν) 2.4 1.8 0 - 3.2. 0 0.4 1 4.4 -2

∑ (Xᵢ - μ ) ( Yⱼ - ν) = 4.8

put all the values of variables in above formula we get,. Cov( X, Y) = 4.8 / 10 = 0.48 ..

To get the x-intercept, we can equate the function to zero

f(x) = (x -g)(x - h) = 0

so (x - g) = 0

which gives x = g

And (x - h) = 0

which gives x = h

Since we have been told that g and h are positive, then it follows that both intercepts are positive
