AleksandrR [38]3 years ago

Answer:

a) 1 in : 6 in

b)  P=32 inches

    A =60 inches ^2

c) P=  16 ft

    A = 15 ft ^2

Step-by-step explanation:

The drawing is 6 inches tall, while the real flag is 3 ft tall

Change ft to inches

3 ft * 12 inches/1ft = 36 inches

drawing : real life

  6                 36

 Divide each by 6

  1                    6

The scale is 1 to 6

So for every 1 inch on the drawing, there is 6 inches in real life


b)  P= 2(l+w) = 2(10+6) = 2(16) = 32 inches

    A = l*w = 10*6 =60 inches ^2

C)

The drawing is 10 inches by 6 inches

Multiply by the scale factor of 6

Real life is     60 inches by 36 inches

Divide by 12 to get back to ft

                            5ft    by 3 ft

P= 2(l+w) = 2(5+3) = 2(8) = 16 ft

    A = l*w = 5*3 =15 ft ^2

Identify the values a, b, and c is the first step in using the quadratic formula to find the solution(s) to a quadratic equation
zlopas [31]

The values are a = 7, b = -9, c = -18.

<u>Step-by-step explanation:</u>

The given quadratic equation is 7x^{2} - 9x = 18

The general form of the quadratic equation is ax^{2} + bx + c = 0

where,

  • a is the coefficient of x².
  • b is the coefficient of x.
  • c is the constant term.

Now, you have to modify the given quadratic equation similar to the general form of quadratic equation.

So, bring the constant term 18 to the left side of the equation for equating it to zero.

⇒ 7x^{2} - 9x - 18 = 0

Compare the above equation with general form ax^{2} + bx + c = 0

⇒ a = 7

⇒ b = -9

⇒ c = -18

Therefore, the values of a, b, and c are 7, -9 and -18.

Please help confused with half life /compound interest problems
jekas [21]
Half life means only half of matter is left, which means half is decayed/radiated. 
Formula for half life is
t/2 = [(elapsed time)*(log2)]/[log(beginning amount/ending amount)]
1. t/2 = [(10)*(log2)]/[log(100/76.1)] = 25.378 minutes.
 t/2 = [10 * 0.301]/[log 1.314] = [3.01]/[0.1186] = 25.378
2. 53.12 = [(T)*(log2)]/[log(15/4)], on solving we get, T = 101.29 days
 53.12 = [T * 0.301]/[log 3.75] = [0.301 * T]/[0.574],
 T = [53.12 * 0.574]/[0.301] = [30.49]/[0.301] = 101.29<span />

Vesna [10]

Answer:

Step-by-step explanation:

The point estimate is the sample proportion.

Considering the sample,

Sample proportion, p = x/n

Where

x = number of success = 137

n = number of samples = 200

p = 137/200 = 0.685

From the information given,

Population proportion = 62% = 62/100 = 0.62

The correct options are

A) Yes, the sample size is greater than 30.

B) Yes, there are at least 10 adults saying they get their news from social media and at least 10 that do not.
