The pounds of pork that Hilda bought based on the information illustrated is 10.9 pounds.

From the information, Hilda bought 10 7/20 lb of beef and some pork and she left with 21 1/4 of meat.

The pounds of pork that she bought  using the decimal form will be:

= Total meat - Pounds of beef

= 21 1/4 - 10 7/20

= 21.25 pounds - 10.35 pounds

If the average score in the United States was 21.2 during a recent year. The average score for Vermont students that year was 7.5% higher than the national average. The average ACT score for Vermont students is: 22.80.

Using this formula to determine the average ACT score

Average ACT score  = Average score in the United states  + ( Average score in the United States × Average score for Vermont students)

Let plug in the formula

Average ACT score  = 21.2 + ( 21. 2 × 7.5%)

Average ACT score  = 21.2 + 1.59

Average ACT score = 22.79

Average ACT score = 22.80 (Approximately)

Therefore we can conclude that the average score is 22.80.

It will take you approximately 24 minutes to paint a 8ft x 5ft wall.

Lets find the area of the given wall,

Area of the wall (A)  = 8ft x 5ft

A = 40sq ft.

It takes 45 minutes to paint a 75 square feet wall, i.e.,

45min = 75 sq. ft.

So, in one min we can paint,

1 min = 75/45sq.ft. = 1.67sq.ft.

Therefore, the time taken to paint the given wall,

= 40sq.ft./1.67sq.ft.

This means that function of (x²+ 1) will give 1/(x²+ 1). To  get f(x), we will simply replace x²+ 1 in the function f(x²+ 1) with x to give;

f(x) = 1/x

How do you define a function?

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given h(x) = 1/(x²+ 1) and g(x) = x²+ 1. If h(x) = f(g(x)) then;

1/(x²+ 1) = f(x²+ 1)

f(x²+ 1) = 1/(x²+ 1)

This means that function of (x²+ 1) will give 1/(x²+ 1). To  get f(x), we will simply replace x²+ 1 in the function f(x²+ 1) with x to give output ;

f(x) = 1/x

The x-intercept is at point (30,0) and the y-intercept is at point (0,25). The graph of the equation is attached below.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that Short-sleeved shirts cost $10 each.  

The Long-sleeved shirts cost $12 each.

The total budget is $300.

The given equation is 10x + 12y = 300

where x is the number of short-sleeved shirts and y is the number of long-sleeved shirts.

We have, 10x + 12y = 300

Substitute the value x = 0

10(0) + 12y = 300

12y    = 300

y = 25

So, the y-intercept will be at 0,25).

Substitute y = 0

10x + 12(0) = 300

10x = 300

x = 30

So, the x-intercept is at point (30,0).

The x-intercept is at point (30,0), that means the number of short-sleeved shirts is 30. The y-intercept is at point (0,25), that means the number of long-sleeved shirts is 25.

Answer:

Perimeter = 2(l+b)

Perimeter = 116

width = x

length = 3x

116 = 2(3x+ x)

116 = 6x+2x

116 = 8x

x = 116/8

x = 14.5

You can verify answer by inputing value of x to see if perimeter is = 116 :

perimeter = 2(l+b)

116 = 2(3(14.5) + 14.5)

116 = 2(43.5 + 14.5)

The range of the function N(t) is [20.25, ∞). The correct option is D.

A function's range is the set of possible output values. For example, the range of the function f(x)=x² on the domain of all real numbers (xR) is the non-negative real numbers, which can be written as f(x)0 (or [0,] in interval notation).

In this question, we have been given that an online streaming service that offers TV shows, documentaries, and movies charges an initial fee of $ 20.25 and an additional monthly membership fee of $3.75.

The total cost, N(t), for a member after t months can be expressed with the function N(t) = 3.75t + 20.25

As t is the number of months, t can take values from 0 to infinity.

For t = 0 years,

N(0) = 3.75(0) + 17.25

N(0) = 0 + 17.25

N(0) = $17.25

For x tends to ∞, the value of function would be ∞. The range will be (20.25,∞).

By taking the quotient between the area that one pound covers and the area of the kitchen, we conclude that Alyssa will need 0.29 pounds of grout.

We know that one pound of grout covers a total of 110 square feet.

Alyssa's kitchen is made of two rectangular segments, one that measures 10.3ft by 2.5 ft, then the area of this rectangle is:

10.3ft*2.5ft = 25.75 ft²

The other rectangle has dimensions of 3.1ft by 2ft, so the area is:

3.1ft*2ft = 6.2ft²

The total area is:

25.75 ft² + 6.2ft² = 31.95 ft²

Now, with one pond of grout, they can cover 110 ft², then the number of pounds that Alyssa needs is:

N = 31.95 ft²/110 ft² = 0.29

Alyssa will need 0.29 pounds of grout.

The cost of one small box is $10 and the cost of one large box of grapefruit is equal to $16.

This type of problem can be solved using linear equations.

If we consider x to be the cost of one small box and y to be the cost of one large box of fruit, the linear equations can be given as;

12x + 5y = 200

4x + 10y = 200

Multiplying the second equation by 3

12x + 5y = 200

12x + 30y = 600

Now by subtracting both equations we get;

-25y = -400

y = -400 / -25

y = 16

Now adding this value of y = 16 in the first equation;

12x + 5y = 200

12x + 5(16) = 200

12x + 80 = 200

12x = 200 - 80

12x = 120

x = 120 / 12

x = 10

Therefore, $10 is the cost of one small box and $16 is the cost of one large box of grapefruit.
