Using percentage error, the error factor is ± 2.15 inches and the smallest size is 40.85 inches and largest size is 45.15 inches.
Percentage ErrorPercent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage. In other words, the percent error is the relative error multiplied by 100.
The formula of percentage error is given as
P.E = [(actual value - estimated value) / actual value] × 100
Since we know the percentage error and actual value, we can find the difference or actual error by;
5 / 100 = x / 43
0.05 = x / 43
x = 2.15
The increase of decrease in size is by a factor of ± 2.15
The smallest size = 43 - 2.15 = 40.85 in
The largest size = 43 + 2.15 = 45.15 in
The smallest and largest size are 45.15 and 40.85 inches respectively

Lines h and j are parallel and cut by transversal k. What is the measure of angle x ?
A. 109°
B. 119°
C. 161°
D. 171°
The value of angle x is 161 degree. So the option B is correct.
In the given question, lines h and j are parallel and cut by transversal k.
We have to find the measure of angle x and choose the correct option.
The diagram of the given question is given below:
From the given diagram using the corresponding angle theorem
x = y
As we know that the angle of straight line is 180 degree.
So x+19 = 180
Subtract 19 on both side, we get;
x = 161 degree
Hence, the value of angle x is 161 degree. So the option B is correct.

Khalid has 2 bags of cornmeal that each contain 25 servings. One serving is 3/4 cup. Khalid is making muffins that require 2.5 cups of cornmeal per batch. What is the maximum number of batches of muffins that Khalid can make using cornmeal?
Using ratios and proportions, he can make 15 batch of muffins from 2 bags of cornmeal
What are Ratios and ProportionsRatio is used for comparing two quantities of the same kind. The ratio formula for two numbers, a and b is expressed as a : b or a/b. When two or more ratios are equal, they are said to be in proportion. The concept of ratio and proportion is based on fractions.
Proportion refers to the equality of two ratios. Two equivalent ratios are always in proportion. Proportions are denoted by the symbol (: :) and they help us to solve for unknown quantities. In other words, proportion is an equation or statement that is used to depict that the two ratios or fractions are equivalent.
In this problem, we know that he has 2 bags of cornmeal
1 bag of cornmeal = 25 serving
2 bags = x
x = 2 * 25 = 50 servings
When making muffins, he needs 2.5 cups in a batch
But 3/4 cup = 1 serving
x cups = 50 serving
x = 50 * 3/4
x = 37.5 cups
1 batch = 2.5 cups
x batch = 37.5 cups
x = 37.5 / 2.5
x = 15 batch
He can make a 15 batches

−36+x<8 whats is the x
Answer:
Therefore, the possible values of x are all numbers less than 8.
Step-by-step explanation:
To find the value of x, we need to isolate the variable on one side of the inequality.
To do this, we can subtract 36 from both sides of the inequality to get -36 + x < 8 - 36.
This simplifies to -36 + x < -28.
Next, we can add 36 to both sides to get x < -28 + 36, which simplifies to x < 8.
Therefore, the possible values of x are all numbers less than 8.
Answer:
Inequality Form:
x<44
Interval Notation:

How do i prove that .......... if F, G, and H are scalar fields?
The cross product or the curl of F, G, and H are zero so they are scaler fields.
What are dot products and cross products?The cosine of the angle between the vectors and their magnitude are combined to form the dot product.
The dot product is represented by A.B = ABCos θ.
The sine of the angle between the vectors and their magnitude are combined to form the cross-product.
The cross product is represented by A×B = ABSin θ.
Given, F × (G × H) = (F . H)G - H(F .G).

Compare the investment below to an investment of the same principal at the same rate compounded annually.
principal: $6,000, annual interest: 6%, interest periods: 6, number of years: 18
The investment compounded annually has a higher final value than the investment you described because the annual compound interest rate is higher.
What is compound interest?
Compound interest is a type of interest that is calculated on the initial principal of an investment as well as any accumulated interest. In other words, compound interest is interest that is earned on both the original principal and on the accumulated interest from previous periods.
To compare the investment you described to an investment of the same principal at the same rate compounded annually, we need to calculate the final value of each investment after 18 years.
For the investment you described, the final value can be calculated using the formula:
FV = P(1 + r/n)^(nt)
Where FV is the final value, P is the principal, r is the annual interest rate, n is the number of interest periods per year, and t is the number of years.
Plugging in the values given in the problem, we get:
FV = $6,000(1 + 0.06/6)^(6*18) = $6,000(1.01)^108 = $12,688.80
For the investment compounded annually, the final value can be calculated using the same formula, but with n = 1:
FV = $6,000(1 + 0.06/1)^(1*18) = $6,000(1.06)^18 = $15,848.75
Hence, the investment compounded annually has a higher final value than the investment you described because the annual compound interest rate is higher. The difference in final value between the two investments is $15,848.75 - $12,688.80 = $3,159.95.

(99,69)
The translated coordinates of B is B'(97,69).
What is translation?A translation is a geometric change in Euclidean geometry that involves moving each point in a figure, shape, or space by the same amount in one direction. A translation may alternatively be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.
Given, point B with coordinates (95, 71) is mapped onto B' through a translation by vector (2,-4).
That means, the translation is 2 units right and 4 units down.
A positive number means moving to the right and a negative number means moving to the left.
The number at the second term represents up and down movement. A positive number means moving up, and a negative number means moving down.
So, B (95, 71) → B' (95 + 2, 73 -4)
B (95, 71) → B' (97, 69)

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We know that the product of slopes of perpendicular lines is -1.

A TPN solution contains 8.25 % amino acids it. If the patient needs 75 grams of protein per day, how much of the TPN solution should the patient receive per day?
The patient should receive 909 mL of the TPN solution per day.
To determine the amount of the TPN solution the patient should receive per day, we need to use the following formula:
amount of TPN solution = (grams of protein needed / percentage of amino acids in TPN solution) × 100
In this case, we are given that the TPN solution contains 8.25% amino acids and that the patient needs 75 grams of protein per day. Substituting these values into the formula, we get:
amount of TPN solution = (75 / 8.25) × 100
amount of TPN solution = 9.09 × 100
amount of TPN solution = 909 mL
Therefore, the patient should receive 909 mL of the TPN solution per day.

Tom wants to know whether a new chest of drawers will fit next to his bed. The chest of drawers would like to buy is 70 centimeters wide.He knows that the room is 86 inches wide. The bed is 67
inches wide. Will the chest fit next to bed?
Answer:
no
Step-by-step explanation:
Tom wants to know if a 70 cm chest will fit in the space left by a 67 in bed in a room 86 in wide.
Available spaceThe space available is 86 in -67 in = 19 in.
Space neededAn approximate conversion between cm and inches is that 10 cm corresponds to about 4 in. Then 70 cm will correspond to 7×4 = 28 inches, much too wide for a 19-inch space.
The chest will not fit next to the bed.
