Answer:

AM=26

Step-by-step explanation:

Since M is the midpoint of the number line, this means that each side is equal to each other. The midpoint evenly splits it up in half, and since each side is equal that means we can set up an equation making x+20 and 5x-4 the same value.

x+20 = 5x-4

Now you simply carry over, so that x is all by itself. I carried the -4 to the other side first. To carry it over you have to add 4 on both sides, leaving this:

x+24=5x

Then I carried the x to the other side by subtracting -x (or if it helps, imagine an invisible one next to the x so it would be -1x) on both sides.

This gives me: 24=4x

Now that all the x's are by themelves, we can divide 24 by 4 to get our x value:

6=x

Now all we need to do is plug that in for the length of AM:

6+20, which equals our final answer 26

I hope you found this helpful :)

Supply and demand are powerful forces in a free market.

maxonik [38]

Answer: Some of the factors that causes a shift in the demand and supply curves are;

(1) Income of the consumers

(2) Change in consumers’ preferences

(3) Price of substitute commodities

(4) Population

Step-by-step explanation: A shift in the demand or the supply curve means a complete movement of the entire curve either to the left or to the right (it must not be confused with a ‘SHIFT ALONG THE DEMAND CURVE’).

One of the factors responsible for this is a change in the income of consumers, because when the consumers’ income increases slightly their purchasing power increases thereby their total quantity demanded would experience an increase.

Also when the taste or preference of the consumers change, it would translate into a different demand entirely. That is, if the consumers begin to have a preference for a brand of a commodity, it simply means they will increase their demand for that commodity and demand less for the one currently being purchased. In other words, the demand curve for the preferred commodity would shift to the right (increase), while the demand curve for the less preferred one would shift to the left (decrease).

Another factor is price of close substitutes. As one commodity is being demanded, another commodity that can satisfy the same purpose is also being demanded. However, the demand for one is usually higher than the other. So if the price for a substitute becomes less, consumers would tend towards that one and the demand for the preferred one would shift to the left. Take detergents for example, if the price of detergent ABC falls low, and consumers have been buying detergent XYZ all along, provided detergent ABC washes clean like XYZ, the demand for ABC would increase and would be depicted as a shift to the right.

Yet another factor is population of the consumers, and this is so because as the population of consumers increases in the market, the total quantity demanded also increases, thereby resulting in a shift in the market demand. It is very important to note that these factors equally apply to the shifts in the supply curves as well.

What is the value of the expression a2 + b3 when a= 1/3 and b= 1/2 ?

Aleksandr-060686 [28]

Answer:

B. $\frac{17}{72}$

Step-by-step explanation:

${a}^{2} + {b}^{3} \\ \\ = \bigg( \frac{1}{3} \bigg)^{2} + \bigg( \frac{1}{2} \bigg)^{3} \\ \\ = \frac{1}{9} + \frac{1}{8} \\ \\ = \frac{8 + 9}{9 \times 8} \\ \\ = \frac{17}{72} \\$

PLEASE HELP WITH GEOMETRY HOMEWORK!! WILL GIVE BRAINLIEST ANSWER TO THE PERSON WHO CAN GIVE ME A ANSWER WILL ALL THE WORK SHOWN

Temka [501]

Answer:

Shaded area = 6^2 * ( pi/3 - sqrt(3)/2 )

= 6.52 square units (to 2 places of decimals)

Step-by-step explanation:

see solution by same author given in

brainly.com/question/17023327?answeringSource=feedPersonal%2FhomePage%2F2

(question 17023327)

Please refer to the diagram for additional letters and measures.

Let

r=radius (OA and PA) of each circle

Area of sector PAOB

= (60+60)/360 * pi * r^2

=pi*(r^2)/3

Area of triangle PAB

= 2* (r cos(60) * r sin(60) /2)

= 2* ((r/2) * r (sqrt(3)/2) /2)

= sqrt(3) * r^2 / 4

= r^2 * sqrt(3)/4

Area of segment AOB

= area of segment PAOB - area of triangle PAB

= r^2 * ( pi/3 - sqrt(3)/4 )

By symmetry, area of shaded area

= area of segment AOB - area of triangle AOB

= area of segment AOB - area of triangle PAB

= r^2 * ( pi/3 - sqrt(3)/4 ) - r^2 * ( sqrt(3)/4)

= r^2 * ( pi/3 - 2*sqrt(3)/4 )

= r^2 * ( pi/3 - sqrt(3)/2 )

Since r = b, we substitute

Shaded area

= b^2 * ( pi/3 - sqrt(3)/2 )

Substitute b=6

area

= 6^2 * ( pi/3 - sqrt(3)/2 )

= 6.522197 square units
