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 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).

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:

Answer:

Area of triangle = (base x height)/2

There are all together 4 triangles and 1 square.

Therefore, surface area = area of square + 4 x area of triangle

height = 5.8 in, base = 6 in. area of square = 6x6 = 36 in^2.

area of 1 triangle = (5.8x6)/2

area of 4 triangles = 2x5.8x6 = 69.6 in^2

surface area = 69.6 + 36 = 105.6 in^2

Step-by-step explanation:

Chef should prepare 4 cakes and 5 batches of pastry in order to achieve maximum profits and his maximum profit or revenue by solving through inequality is $260.

Given Chef uses 5 cups of cake batter for 1 cake and 4 cups of batter for 1 batch of cupcakes. Chef wants to make at least 4 cakes. Profit on 1 cake is $35 and $30 for 1 batch of cupcake.

let the number of cakes be x and the number of batches of cupcakes be y such that

5x+4y<=40--------1

x>=4---------------2

Maximize Profit=35x+30y

Inequalities contains different signs so we have to change one inequality.

5x+4y<=40

-x<=-4

Now assume them equalities

5x+4y=40-------3

-x=-4

multiply second equations by 5

-5x=-20-----------4

now  add 3 and 4

5x+4y-5x=40-20

4y=20

y=5

now put the value of y in 5x+4y=40

5x+4*5=40

5x+20=40

5x=20

x=4.

Maximum Profit=35x+30y

=35*4+30*5

=$260

Hence chef should make 4 cakes and 5 batches of pastry and maximum profit of $260.

The value of c is 3

The complete question is in the attached image

The function definition is given as:

g(x) = f(x) - c

From the graph of functions f(x) and g(x), we can see that:

f(x) is shifted down by 3 units to get to g(x)

This means that:

g(x) = f(x) - 3

By comparing g(x) = f(x) - 3 and g(x) = f(x) - c,

We have:

c = 3

Hence, the value of c is 3

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.

[tex]A=6.1\cdot2.6[/tex]

Multiply.

[tex]A=\boxed{15.86}[/tex]

Note that the answer is given in square miles ([tex]\text{mi}^2[/tex]) since both of the measurements used are in miles.

Considering the given information in the question, the value of x is [tex]12^{o}[/tex], and that of y is [tex]7.5^{o}[/tex].

A transversal is a line that cuts through two given parallel lines. Thus it intersects each parallel line at a point, forming four angles each.

From the given information in the question, it can be inferred that:

the given bottom right angle of the first intersection and the bottom right angle with the second intersection are congruent (corresponding angle property).

So that,

[tex](5x+4y)^{o}[/tex] = [tex](12y)^{o}[/tex]

[tex]5x^{o}[/tex] = [tex]12y^{o}[/tex] - [tex]4y^{o}[/tex]

[tex]5x^{o}[/tex] = [tex]8y^{o}[/tex]............ 1

Also given that the top right angle at the second intersection is a right angle, then;

    [tex]12y^{o}[/tex] + [tex]90^{o}[/tex] = [tex]180^{o}[/tex] (sum of angles on a straight line)

This implies that;

    [tex]12y^{o}[/tex] = [tex]180^{o}[/tex] -    [tex]90^{o}[/tex]

       [tex]12y^{o}[/tex]  =     [tex]90^{o}[/tex]

So that,

y = [tex]\frac{90}{12}[/tex]

y = [tex]7.5^{o}[/tex]

Thus substituting the value of y in equation 1, we have;

[tex]5x^{o}[/tex] = [tex]8y^{o}[/tex]........ 1

     = 8(7.5)

5x = 60

x = [tex]\frac{60}{5}[/tex]

x = [tex]12^{o}[/tex]

Therefore, x = [tex]12^{o}[/tex] and y = [tex]7.5^{o}[/tex]

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°.
