Toni is at a dock on a bank of a straight river that is 1 mile wide and wants toreach the barge toll gate on the other side, so he can warn the guards about the stolengoods on an approaching barge. The toll gate is 4 miles downstream on the opposite bank,and Toni want to get there by first rowing his boat to somewhere (call it point P) on theopposite bank and then walking the remaining distance × to the toll gate. He can row at 4mph and walk at 2 mph. Express the total time 7, in terms of x, that he takes to go from thedock to the toll gate.

Given the expression:

a - 5 - b

we want to evaluate it when a = 10 and b = 4. To do it, we have to replace these values into the equation as follows:

10 - 5 - 4 = 1

Answer:

Step-by-step explanation:

the absolute value function always delivers only the positive value of anything inside the absolute function.

therefore, x is 9 and only 9.

Ice is colder than water due to its more heat absorbing capacity then water and steam is hotter than water due to high heat transfer rate then water.

What is specific heat capacity ?

In scientific terms, a specific heat capacity is the quantity of heat (J) absorbed by a material every time its temperature goes up 1 K (or 1 °C), given in J/(kg K) or J/(kg °C) per unit mass. formulae for specific heat capacity is given by :

Q = mCΔT

Here the given statement is :

If the temperature of water is between the temperatures of ice and steam, then ice is colder than water and steam is hotter than water.

The above statement is justified below :

The steam exhibit more energy than water at the same temperature that is 100° C. The steam uses the latent heat of vaporization so as to get vaporized and water do not exhibit energy and also, The arrangement of molecules in substances is widely influenced by the state of the matter of the substance. In this way, in solids the molecules have a fix organization and are closely packed due to this, solids have both a defined shape and volume; in liquids the molecules are still close to each other but there is no a defined structure and therefore liquids have a defined volume but not a defined shape; finally, in gases molecules do not follow an orderly arrangement and there is more space between them which makes them not have a define volume or shape.

According to this, we can say that Ice is colder than water due to its more heat absorbing capacity then water and steam is hotter than water due to high heat transfer rate then water.

The following statement "A supply shock is a sudden shortage of a good" is true.

A supply shock is an unexpected incident that abruptly affects the supply of a product or commodity, resulting in an unanticipated change in price. Supply shocks can be negative, resulting in a fall in supply, or positive, resulting in an increase in supply.

Assuming that aggregate demand remains constant, a negative (or unfavorable) supply shock causes a product's price to rise, whereas a positive supply shock causes the price to fall.

The slope-intercept form equation for a line that contains point (0, 5) and has a slope of 5/4 is y = (5/4)x + 5

In this question, we have been given a point (0, 5) and a slope 5/4

We need to write the slope-intercept form equation for a line that contains point (0, 5) and has a slope of 5/4

Using the formula for the point-slope form equation of a line:

(y - y1) = m(x - x1)

y - 5 = (5/4)(x - 0)

y - 5 = (5/4)x

y = (5/4)x + 5

which is slope-intercept form of line.

here slope = 5/4 and y-intercept = 5

Therefore, the slope-intercept form equation for a line that contains point (0, 5) and has a slope of 5/4 is y = (5/4)x + 5

Answer:

y = x-13

Step-by-step explanation:

So this question asks for two numbers. Let's call them x and y.

Since we know that x is larger than y, and the difference between them is 13, x must be greater than y by 13. So, x = y + 13
x = y + 13 isn't what the question is asking for though, so we have to isolate y to make one side contain only x and numbers. To do that, subtract both sides by 13 to get:
x - 13 = y

rearrange:

y = x - 13

The given line equation is y=1.

The general form of the line equation is

Comparing this equation with y=1, we get

Compare coefficient of x and constant term, we get

Here m=0 is the slope of the line y=1.

Hence the slope of the line y = 1 is zero.

The angle of elevation reduces. The distance between points A and B is roughly 1,269.9 ft.

The distance between point A and the lighthouse is 968 feet.

The angle of elevation from point A to the lighthouse is 7 degrees.

Elevation angle from point B to the lighthouse = 3°

The distance between points A and B.

tan 7° = Height of the sea /  968 feet

tan(7°) 968 feet 118.86 feet = height to the lighthouse

We have from point B;

tan 3° = 118.86 / Horizontal distance from B to HL

Therefore;

Horizontal distance from LH to boat = 118.6 / tan 30° = 2237.9 = feet

Therefore;

D is the distance between A and B.

D = Horizontal distance between B and LH - Horizontal distance between A and LH

A to B distance = 2237.9 feet − 968 feet 1269.9 feet

The distance between points A and B is 1,269.9 ft.

The sum of the length around a square is known as the perimeter thus the possible length of each side of the chicken pen assuming it to be square is 12.5 feet.

Perimeter is the addition of an external measure of sides it will always positive.

A perimeter is a length and has a degree of the unit as one.

Perimeter of square = side + side + side + side

Let's assume the chicken pen to the square in order to find the length of each side.

Now since fencing is fitted around the sides so it will be the same as the perimeter of the square.

Perimeter of square = 4 × side

4 × side = 50

Side = 50/4 = 12.5 feet.

Answer:

  SSA is not a valid congruence theorem

Step-by-step explanation:

Given a figure with opposite sides the same length, and their ends joined by a line through the midpoint of the segment joining their other ends, you want to know why the shape is not a parallelogram.

The recognized congruence theorems are ...

  AAS, ASA, SAS, SSS

The "would be" SSA theorem is not included, because the case where the angle is opposite the shortest of the two sides does not uniquely specify the triangle.

In this diagram, the sides marked with 2 and 1 hash marks are sequential with the vertical angle where the diagonals cross. Hence the only basis for claiming the triangles congruent is SSA.

The basis for claiming congruence is not a recognized congruence theorem, so we cannot conclude the triangles are congruent. (CPCTC does not apply.)

__

Additional comment

As we noted, the SSA criterion for congruence fails if the given angle cannot be demonstrated to be opposite the longest side. The attachment shows the case where the single-hash segment is longer than the double-hash segment, so there are two ways to draw the figure. One is a parallelogram, the other is not.

The HL congruence theorem is essentially SSA, where the A is the right angle. If the angle can be demonstrated to be the largest in the triangle, then the SSA theorem can be used (as for right- or obtuse triangles).

As the attachment shows, there is nothing in this geometry that requires the vertical angle(s) opposite the double hash be the largest.
