Twice a number increased by twenty is at least eighty-five. Select all possible values of the number.

The sum will be 46 which is the nearest combinational value that could be deduced from the digits 1, 2, 3, and 4.

Let's check all the combinations which can be possibly used,

34 + 21 = 46, which is 4 numbers less than 50 so far the nearest.

43 + 12 = 55, which is 5 numbers more than 50.

32 + 41 = 73, which is 23 numbers more than 50.

32 + 14 = 46, which is 4 numbers less than 50 so far the nearest.

23 + 41 = 64, which is 14 numbers more than 50.

So the two combinations are deduced after permutation and a combination of numbers that are 3 and 4 + 2 and 1 and another is 3 and 2 + 1 and 4.

When two parallel lines are intersected by a transversal 8 angles are formed.

Alternate exterior angles: These angles are located outside the parallel lines but on the opposite side of the transversal.

Alternate interior angles:

These angles are located inside the parallel lines but on the opposite side of the transversal.

Corresponding angles: These angles are located at the same relative position on the same side of the transversal.

The measurement deviates from the mean by more than 100 standard deviations.

It's a way to gauge how widely apart each data point is from the mean. The standard deviation formula comes in two different forms: Standard deviation for the population When you can measure the entire population or the entire collection of data, you use the population version of the formula. Experts in statistics have determined that measurements that fall within a 2 SD range of the true value are more accurate than those that do not..

b) yes, it is a rational number

Grayce has 0.825 g of diamonds and Morgan has 0.824 g of diamonds. Grayce has more grams of diamonds

From the question, we are to determine the person that has more grams of diamonds

From the given information,

"Grayce has three diamonds that weigh 0.275 g each"

and

"Morgan has two diamonds that weigh 0.412 g each"

Thus,

The total mass of Grayce's diamonds is 3 × 0.275 g

3 × 0.275 g = 0.825 g

Also,

The total mass of Morgan's diamonds is 2 × 0.412 g

2 × 0.412 g = 0.824 g

Since 0.825 is greater than 0.824,

Then,

Grayce has more grams of diamonds.

The result of the function n(x)= [tex]-1-\frac{1}{3}x+1\frac{2}{3}[/tex] when x = -2,0 and 5

n(-2) = 4/3

n(0) = 2/3

n(5)  = -1

The function is n(x)= [tex]-1-\frac{1}{3}x+1\frac{2}{3}[/tex]

The function is an equation which expression the relationship between one variable and another variable. If one variable is independent variable then another variable will be dependent variable.

The function is n(x)= [tex]-1-\frac{1}{3}x+1\frac{2}{3}[/tex]  when x= -2,0 and 5

Here we have to substitute the value of x in the given function

n(-2) = -1-(1/3)(-2)+5/3

= -1+(2/3)+5/3

= 4/3

n(0) = -1-(1/3)(0)+5/3

= -1+(5/3)

= 2/3

n(5) = -1-(1/3)(5)+5/3

=  -1-(5/3)+(5/3)

= -1

Hence, the result of the function n(x)= [tex]-1-\frac{1}{3}x+1\frac{2}{3}[/tex] when x = -2,0 and 5

n(-2) = 4/3

n(0) = 2/3

a. Expression for length L in terms of x is  L = 1040 - 2x

b. Expression for the area of the pasture in terms of L and x, A = Lx

c. Expression for the area of the pasture in terms of x only = x (1040 - 2x)

d. The area of the pasture will enclose greater than or equal to 60 square feet

Given data

length of fence = 1040 ft

length if the pasture = L

width of the pasture = x

Expression for length L in terms of x

from the figure we can see that the fenced part is 3 sides which include 2 widths and 1 length. So we represent this with the expression below

L + x + x = 1040

L + 2x = 1040

L = 1040 - 2x

Expression for the area of the pasture in terms of L and x

Area of the pasture,  A = L * x

A = Lx

Expression for the area of the pasture in terms of x only

= L * x

and L = 1040 - 2x

= x (1040 - 2x)

A sentence that makes the area to enclose at least 60 000 square feet.

total cost of metal in the pattern is £24.6

To compare two values is to use a ratio. A proportion is formed when two ratios have the same value. Choose whether the ratio is part-to-part or part-to-whole before you write it.

20 straight line cost £12

12 ÷ 20 = 0.6 per straight line

straight line : cost of one arc = 2:3

arc = 0.6 x (3/2) = 0.9

The solution set for the inequality is p > -9.4. See attachment below for the graph.

An open circle is used when the inequality sign involved is ">" or "<". That is, it is used for numbers that are less than or greater than.

An arrow shaded to the right means the solution set is greater than a given value, while an arrow shaded to the left means the solution set includes all values that are less than a given value.

Given the inequality, p + 3.6 > −5.8, solve for p:

p + 3.6 > −5.8

Subtract 3.6 from both sides

p + 3.6 - 3.6 > -5.8 - 3.6

p > -9.4

Thus, the solution set would be all the values that are greater than -9.4. The graph is shown below.

99th term of the given arithmetic sequence 7, 3, -1, -5, ... is -385.

We are provided with the arithmetic sequence mentioned below;

7, 3, -1, -5, ................. -385

[tex]a_{n}[/tex] =  [tex]a_{1}[/tex] + (n−1)d

where [tex]a_{1}[/tex] is the first term, [tex]a_{n}[/tex] is the nth term and d is the difference between a term and its previous term.

With the help of provided arithmetic sequence we can write;

[tex]a_{n}[/tex] = -385

[tex]a_{1}[/tex] = 7

d = difference between a term and its previous term = 3 - 7 = -4

Put these values in equation 1 , we will get

-385 = 7 + (n-1) (-4)

392 = 4n -4

4n = 396

The dimensions of the region which enclose the maximum area is a side of 162 feet and vertical segment of 108 feet

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

Let x represent the side parallel to the vertical segment and y represent the other side. If the farmer has 648 feet of fencing, hence:

x + x + y + y + x = 648

3x + 2y = 648

y = 324 - 1.5x

Area (A) = xy

A = xy

A = x(324 - 1.5x)

A = 324x - 1.5x²

The maximum area is at A' = 0, hence:

A' = 324 - 3x

324 - 3x = 0

3x = 324

x = 108 feet
