For the regular hexagon below, if BC = 9 m and AP = 8 m, find it's area.

The required scale factor for the dialed triangle is given by SF= 6.28

A triangle with vertices at A(0,0), B(0,4), and C(6,0) is dilated to yield a triangle with vertices at A(0,0), (B(0,10), and C (C(15,0).

The scale factor is defined as the ratio of modified change in length to the original length.

Since, the height and base of the triangle is y coordinate of B and x coordinate of c is given by 4, 6
Area of triangle =1/2(base x height)
                         = 1/2 (4 x 6)
                         =   4.8
Similarly, for dilated triangle
Area of dilated triangle =  30

Now, scale factor(SF) = area of dilated triangle \ area of triangle
SF = 30/4.8
SF = 6.25

Thus, the required scale factor is SF = 6.25

The new amount of neon gas when the temperature drops is 2.30L.

Charles's law

Charles's law states, "The volume occupied by a particular amount of gas is directly proportional to its absolute temperature.

Initial temperature of gas T₁ = 50 ° C = 323.15K

Initial volume of gas V₁ = 2.5L

Final temperature T₂ = 25 ° C = 298.15K

Final capacity V₂ =? Neon gas, substitute the given value into the above equation:

V₁ / T₁ = V₂ / T₂

V₂ = V₁T₂ / T₁

V₂ = (2.5L × 298.15K) ) / 323.15K

V₂ = 2.30 l

Therefore, the new volume when the temperature of the neon gas drops is 2.30l.

Answer:

A. 2.3

Step-by-step explanation:

The area of a parallelogram is simply its base (6.1 miles) multiplied by its height (2.6 miles).

Substitute the values into the formula for area.

Step-by-step explanation:

The measure of an angle formed by a Secant and a tangent drawn from the outside point of a circle is half the difference of the intercepted arcs.

   [tex]\sf \angle E =\dfrac{arc \ CF - arc \ DF}{2}[/tex]

        [tex]\sf53 =\dfrac{arc \ CF-41}{2}[/tex]

  53*2  = arc CF - 41

   106    = arc CF - 41

106 + 41 = arc CF

   [tex]\sf \boxed{\bf \ arc \ CF = 147^\circ}[/tex]

9)  If two secants inside a circle, then the angle formed is equal to the half of the sum of intercepted arcs.

The proportion of people who preferred foreign cars than domestic cars is 0.24 and the confidence interval  for the population proportion of new cars over domestic cars of 98% confidence interval is (641.955,642.045).

Given sample size of 2676 and number of people preferred foreign cars than domestic cars is 642.

We have to calculate the proportion of people who preferred foreign cars than domestic cars and the confidence interval which shows the confidence interval of 98%.

Number of people prefer foreign cars than domestic cars=642

Sample size=2676

Proportion=642/2676

=0.2399

=0.24   (After rounding off)

Now we will find confidence interval.

X=642

n=2676

z value for the confidence interval 98% is 2.33

Confidence interval =X± z*s/[tex]\sqrt{n}[/tex]

Upper =642+2.33*1/[tex]\sqrt{2676}[/tex]   (we have taken s=1)

=642+0.045

=642.045

Lower=642-2.33*1/[tex]\sqrt{2676}[/tex]

642-0.045      (putting values in formula given above)

=641.955

Hence the proportion of people preferred foreign cars than domestic cars is 0.24 and the confidence interval is (641.955,642.045).

Answer:

7.5 cm

Step-by-step explanation:

The perimeter of a rectangle is the sum of the length of all its sides.

Perimeter of rectangle= 2(length +breadth)

Given: perimeter= 24 cm, breadth= 4.5 cm

Substitute the given information into the formula:

24= 2(length +4.5)

Divide both sides by 2:

length +4.5= 12

Subtract 4.5 from both sides:

length

= 12 -4.5

= 7.5

Thus, the rectangle is 7.5 cm long.

Answer:

C. About 50 percent is soccer, 25 percent is baseball, 25 percent is basketball.

Step-by-step explanation:

400 students at a sports camp.

200 play soccer, which is 50% or half of the students at the sports camp.

100 play baseball, which is 25% or a quarter of the students at the camp.

100 play basketball, which is also 25% or a quarter of the students at the camp.

So, the circle graph that shows soccer 50%, baseball 25%, and basketball 25%, is the answer.

Answer:

Other answer is wrong. The answer is this choice

The table C correctly shows the marginal frequencies.

A two-way table is a way to display frequencies or relative frequencies for two variables.

One of the variables is represented using rows and the other one using columns.

They are used to see if there is any relationship between the two variables.

Given that, the ages and grades of some of the 19 girls on a club soccer team are shown in the given table.

We need to select the table showing the correct marginal frequencies.

So, we see that,  

Table A and Table D add up to a total of 21 girls.

The question says there are 19 girls, so those two are eliminated.

Table B's data doesn't even add properly so that is eliminated too.

This leaves Table C.

The equation which represents the measure of the unknown angles is x + x + 10 =130. Hence, option C is correct.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the data given in the question,

As per the rules, the sum of the three sides of a triangle is 180°.

The angles are x, x+10, and 50.

Now,

x + x + 10 + 50 = 180

x + x + 10 = 180 - 50

x + x + 10 = 130°.
