this is an accurate equation because the square root of 3•3•5•5•7•7 is 105 & 3•5•7 is also 105, making them equal! i’m sorry i also don’t understand what the question is asking, but i hope this helped :/

Answer:

Step-by-step explanation:

take 42 degree as reference angle

using sin rule

sin 42=opposite/hypotenuse

0.66=6.4/x

x=6.4/0.66

x=9.69

x=9.7

Answer:

The answer is [tex]y=3x-10[/tex]

Step-by-step explanation:

You use the formula [tex]y_{2} -y_{1} /x_{2} -x_{1}[/tex]

Which will give you 3. So the slope is 3/

Then you continue with the equation-  [tex]y=mx+b[/tex] (m represents the slope which is 3) We use then use any point but I used (4,2) to plug into the equation.

After using that equation, you get the y-intercept as -10. So, the equation is [tex]y=3x-10[/tex]

The liquid which has passed through the filter is called the filtrate. Filtration is a physical or chemical separation process that separates solid matter and fluid from a mixture using a filter medium that has a complex structure through which only the fluid can pass.

Answer:

10,404/334,084

Step-by-step explanation:

Given the polynomial

289r^2 - 102r + c

We are to find the value of c that will make it a perfect square

Divide through by 289

289r²/289 - 102r/289 + c/289

Half of the coefficient of r is 1/2(102/289)

Half of the coefficient of r = 102/578

Square the result

r² = (102/578)²

r² = 10,404/334,084

Hence the required constant is 10,404/334,084

Answer:

x = 2 , y = 4.

(2,4)

Step-by-step explanation:

Simultaneous equation:

2x - y = 10    E1

y = [tex]-\frac{1}{2}x[/tex] + 5    E2

Substitute equation 2 into equation 1 for the y value.

2x -  [tex]-\frac{1}{2}x[/tex] + 5  = 10

2x -  [tex]-\frac{1}{2}x[/tex] = 5

2x +  [tex]\frac{1}{2}x[/tex] = 5

[tex]\frac{5}{2} x[/tex] = 5

x = 2

Substitute the x value  into  equation 2.

y = [tex]-\frac{1}{2}2[/tex] + 5

y = -1 + 5

y = 4

Answer:

95 ft²

Step-by-step explanation:

A = 1/4 x pi x diameter

A = 1/4 x 3.14 x 11²

A = 0.785 x 121

A = 94.985 ft²

Answer:

  B.  66 m

Step-by-step explanation:

Map and ground distances are proportional:

  ground/map = ground/(12 cm) = (11 m)/(2 cm)

  ground = (12 cm)(11 m/(2 cm)) = 66 m

The distance from A to B is 66 m.

Answer:

a =55

b =16

c = 25

d = 9

Step-by-step explanation:

of means multiply  is means equals

20% of a is 11

.20 a = 11

Divide by .20

a = 11/.20

a=55

75% of b is 12

.75 b =12

Divide by .75

b = 12/.75

b = 16

80% of c  is 20

.80 c =20

Divide by .80

c = 20/.80

c =25

200% of d is 18

2.00 d = 18

Divide by 2.0

d = 18/2

d =9

Step-by-step explanation:

d = √(15-10)²+(-6-3)²

=√5²+(-9)²

= √25+81

=√106

10.3 units

Answer:

12

Step-by-step explanation:

Answer:

<ADB = 75 degrees

Step-by-step explanation:

We know, a straight line has an angle of 180 degrees.

A = (180-143) = 37 degrees.

A + C = (37 + 38) = 75 degrees.

The angles of a triangle will always add up to 180 degrees.

<ADC = (180-75) = 105 degrees.

So,

<ADB = (180-105) = 75 degrees.

Answer:

2.36 miles

Step-by-step explanation:

radius, r = 3 miles

∅ = 45°

Length of an arc = ∅/360 * 2πr

= 45/360 * 2 * 3.14 * 3

= 2.36 miles

Hope this answer helps you :)

Have a great day

Answer:

We are 95% confident that the proportion of all Money magazine subscribers that made money in the previous year from their investments is between 0.6904 and 0.8218

Step-by-step explanation:

The confidence interval gives a range of values for which a population proportion will fall based on a given level of confidence, in this case it is 95%. This interval is calculated using the sample proportion. The sample proportion in this case is based on a number of samples examined. The interval we obtain in this case (0.6904; 0.8218) is the estimated range which we expect the population proportion to fall ; with a 95% confidence.

Answer:

  $2,210.16

Step-by-step explanation:

The applicable formula for the account balance is ...

  A = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years. Here, we have P=2000, r=0.02, n=12, t=5. The balance is ...

  A = $2000(1 +0.02/12)^(12·5) = $2210.16

Answer:

ok so so here are the numbers equal to 6

1,5

5,1

2,4

4,2

3,3

so five options and there are 36 possible outcomes(6*6)

so 5/36 or 0.14

Hope This Helps!!!

The solution is,  the probability that the sum of the two dice is greater than or equal to six is 0.14.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we get,

You roll two six-sided dice numbered from one through six.

so here are the numbers equal to 6

1,5

5,1

2,4

4,2

3,3

so five options and there are 36 possible outcomes(6*6)

we get, sample space = 36

favorable outcome = 5

probability = 5/36

so 5/36 or 0.14
