The midpoint of AB is M (-2,5). If the coordinates of A are (1,7), what are the coordinates of B?

Answer: 9y-4

Step-by-step explanation:

13y-4y=9y

7-11=-4

Answer:

13y+7-11-4y

13y-4y+7-11

9y-4 ans

Step-by-step explanation:

first combine the like terms along with their front sign

then sbtract 13y by 4y ,after subtract 7 from 11

[ here 7 have (+) and 11 have (-) before itself

according to the rule,(+) + (-) = (-)

hence we have to subtract 7 from 11 and put the (-) before answer]

but put sign (-) before the answer because we should always put that sign before answer which have more value

Three lots with parallel side boundaries extend from the avenue to the boulevard.

x + y + z = 140 meters

According to the proportion theorem,

Solving for x, using cross multiplication:

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40

z = 7x/8

Now, the third proportions,

y/30 = z/35

Solving for y,

y = 30z/35

y = 6z/7

x + y + z = 140

4y/3 + 6z/7 +  7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substituting z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520

Now,

Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,

We know that

y = 3x/4

so,

y = 40

And,

z = 7x/8

Z = 46.66

Step-by-step explanation:

The third angle of the triangle must have a measure of 180° minus the sum of the other two angles, which is 180° - (46° + 73°) = 61°. Therefore, the measure of the missing angle is 61°.

The internal angles of a triangle are measured in degrees and are known as triangle angles. The sum of a triangle's angles is always 180°.

Triangle angles are classified into three types: acute angles, right angles, and obtuse angles.

An acute angle is one that is smaller than 90 degrees. This is the most common form of angle in a triangle and is regarded the most desirable.

A right angle is one that is exactly 90 degrees. This sort of angle is the most stable and sturdy in a triangle, therefore it is usually employed to make a triangle.

An obtuse angle is one that is larger than 90 degrees but less than 180 degrees. This form of angle is common in triangles, however it is less desirable than an acute angle.

The sum of the three angles of a triangle is always 180°. Acute angles are the most desirable and stable, whereas obtuse angles are present in certain triangles but are not as ideal.

In the given question,

The measure of the missing angle is 180° - (46° + 73°).

180° - (46° + 73°) = 180° - 119° = 61°

Therefore, the measure of the missing angle is 61°.

The triangles in this problem are similar using the SSS theorem.

Similar triangles are triangles that share these following two features:

For this problem, we have that the two triangles share two common angle measures.

A triangle is composed by three angles, and the sum of their measures is of 180º, hence the third angle measure will be equal for both triangles.

As the angle measures are equal, the side lengths are going to be proportional, thus the triangles are similar by the SSS theorem.

The constant of proportionality for this variation is 0.174cm/gallon .

Every relationship that always maintains the same ratio is referred to be proportionality. For instance, the average amount of apples per tree determines the proportionality between both the quantity of apples in a crop and the number of trees in the orchard.

Let the amount a tree grows in one month be - x  

The amount of water   given be -  y

If the amount a tree grows in one month is directly proportional to the amount of water given, then

x ∝ y

x = ky

k is defined as the constant of proportionality

k = [tex]\frac{x}{y}[/tex]

Given

x = 4cm

y = 23 gallons

k = [tex]\frac{4}{23}[/tex]

Answer:1.25(400)

Step-by-step explanation:

The expected value of the sample mean of the values obtained in these 300 tosses is 3.5

300 fair throws of a six-sided die are made.

The expected value of the sample mean of the results acquired from these 300 tosses must be determined.

Six sides make up a dice:

Every side of a fair dice has an equal chance of happening.

Now, each side's likelihood of being present is 1/6.

Now, the sample mean of the values collected in these 300 tosses is predicted to be equal to:

E(x) = Σx P(x =x)

= 1*1/6 + 2*1/6 + 3*1/6 + 4*1/6 + 5*1/6 + 6*1/6

= 1/6 + 2/6 + 3/6 + 4/6 + 5/6 + 6/6

= 1/6 (1+2+3+4+5+6)

= 1/6 (21)

= 21/6

E(x) = 3.5

Hence, the expected value of the sample mean of the values obtained in these 300 tosses is 3.5

Step-by-step explanation:

50/3 is the minimum function value.

∇f(x,y,z)=(2x,4y,6z)

∇g(x,y.z)=(1,2,3)

set up the system of equations:

2x=λ

4y=2λ

6z=3λ

x+2y+3z=10-----(1)

solve the first three equations for λ.

2x=λ

2y=λ

2z=λ

From these three equations, we conclude that

x=y=z.

Plug this into the constant equation.

x+2y+3z=10

x+2x+3x=10

6x=10

x=3/5

Therefore, there is one point of interest and it occurs at (5/3,5/3,5/3).

Answer:

x= 4/3

Step-by-step explanation:

Think the negative sign outside the parentheses as -1. Then do distributive property to the numbers inside the parentheses.

-1 x 3x and -1 x -12

That equals to -3x + 12 so now your entire equation is -3x + 12 = 9x - 4. Now lets take away 9x from both sides like this,

9x - 9x and -3x - 9x.

That equation is now -12x + 12 = -4.

Now subtract 12 from both sides like this,

12 - 12 and -4 - 12.

And then you have -12x = -16.

Now you divide both numbers by -12 like this,

-12x/-12 which equals to just x and then do -16/-12 which would equal as 1.3333 and repeating but, it can be put as 4/3 for a clearer answer.

The total number of clients with a BMI of 25.9 or higher is therefore equal to 1 * 2.6 + 3 * 2

The total amount of money she would need to give in discounts next month can be found by calculating the total number of clients with a BMI of 25.9 or higher. To calculate this, the frequencies of each BMI range need to be multiplied by the width of the corresponding bar. The total amount of money she would need to give in discounts is then equal to the total number of clients with a BMI of 25.9 or higher multiplied by $50.

Using the histogram, the number of clients in each BMI range are: 18.1-20.7 (1), 20.7-23.3 (3), 23.3-25.9 (5), 25.9-28.5 (2), 28.5-31.1 (1).
