FIRST TO ANSWER CORRECTLY GETS 22 POINTS AND BRAINIEST

Answer:

181.7m

Step-by-step explanation:

The set up is a right angled triangle with;

Height of the light house = 25m = opposite side

The distance of the boat from the base = 180m = Adjacent

The distance of the light beam from the house = Hypotenuse = x

Using pythagoras theorem;

x² = 25²+180²

x² = 625+32400

x² = 33025

x = √33,025

x = 181.7m

Hence distance of the light beam from the top of the lighthouse to the ground is 181.7m to the nearest tenth

Answer:

3. the numbers between -5 and 5

Step-by-step explanation:

Let set A= [tex]\{x| x>-5\}[/tex] and set [tex]B=\{x | x<5\}[/tex].

The solution set of A and B is the solution set of A∩B

The solution set of A is all the real number x which is greater than -5.

The solution set of B is all the real number x which is less than 5.

Therefore, the solution set of A∩B is all the real numbers between -5 and 5.

Hence, option (3) is correct.

Well on Christmas I just made chocolates and ate them-

As for New Years, Happy New Year! :D

Answer: I got a kitty headphones, and this games board and also a letter of my name :)

Step-by-step explanation:

Given:

The graph of cost of taxi with respect to number of miles.

To find:

The formula for C in terms of n.

Solution:

In the given graph x axis represents the number of miles (n) and y-axis represents the cost of taxi (C).

From the given graph it is clear that, the line passes through the points (0,3) and (5,6). So, the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-3=\dfrac{6-3}{5-0}(x-0)[/tex]

[tex]y-3=\dfrac{3}{5}(x)[/tex]

Adding 3 on both sides, we get

[tex]y=\dfrac{3}{5}x+3[/tex]

Putting y=C and x=n, we get

[tex]C=\dfrac{3}{5}n+3[/tex]

Therefore, the required formula is [tex]C=\dfrac{3}{5}n+3[/tex].

Answer:

c=3/5n+3

Step-by-step explanation:

Answer:

19 - 2^(7/4)√3  or

13.174 to nearest thousandth.

Step-by-step explanation:

I am interpreting this as x^2 - 2√(2x) + 1

p(3√2) = (3√2)^2 - 2√(2*3√2) + 1

= 18 - 2√(6√2) + 1

= 19 - 2* √6 * 2^1/4

= 19 - 2*√2*√3*2^1/4

= 19 - 2^(7/4)√3.

=  13.174 to the nearest thousandth.

Answer:

The fraction is 41/99.

Step-by-step explanation:

The steps are :

[tex]let \: x \: be \: fraction,[/tex]

[tex]x = 0.414141.....[/tex]

[tex]100x = 41.414141.....[/tex]

[tex]100x - x = 41.414141..... \: - \: 0.414141.....[/tex]

[tex]99x = 41[/tex]

[tex]x = \frac{41}{99} [/tex]

Answer:

its 9.2

Step-by-step explanation:

Well i counted 7 units (x-axis) and 6 units (y axis). 6 squared is 36 and 7 squared is 49. Add them together and get 85. Square root 85 and youll get 9.21954445729. Round it to the nearest tenths and get 9.2

Answer:

B. 4/3

Step-by-step explanation:

[tex] \frac{ {4}^{ - 3} . {3}^{4} . {4}^{2} }{ {3}^{5} . {4}^{ - 2} } \\ \\ = \frac{ {4}^{ - 3} . {4}^{2 + 2} }{ {3}^{5 - 4}} \\ \\ = \frac{ {4}^{ - 3} . {4}^{4} }{ {3}^{1}} \\ \\ = \frac{ {4}^{4 - 3} }{ {3}^{1}} \\ \\ = \frac{ {4}^{1} }{ {3}^{1}} \\ \\ = \frac{4}{3} [/tex]

Answer:

B. 4/3

Step-by-step explanation:

Answer:

D. Prime

I just took the test

Step-by-step explanation:

Answer:

1) 4

2) 2

3) 5

4) 8

Step-by-step explanation:

All you have to do in this question is to substitute what they are telling you.

First blank:

They told us that m is 0 so if we plug that into the equation we can get s.

[tex]2m+4s=16\\2(0)+4s=16\\4s=16\\s=4[/tex]

In this one if m is 0, s will have to be 4.

Second blank:

They told us that s is 3 so if we plug in that into the equation we can get m.

[tex]2m+4s=16\\2m+4(3)=16\\2m+12=16\\2m=4\\m=2[/tex]

In this one if s is 3, m will have to be 2.

Third blank:

They told us that m is -2 so if we plug that into the equation we can get s.

[tex]2m+4s=16\\2(-2)+4s=16\\-4+4s=16\\4s=20\\s=5[/tex]

In this one if m is -2, s will be 5.

Fourth blank:

They told us that s is 0 so if we plug into the equation we can get m.

[tex]2m+4s=16\\2m+4(0)=16\\2m=16\\m=8[/tex]

In this one if s is 0, then m will be 8.

Answer:

S=smaller number; L=larger number=3S

.

4S+5L=133

4S+5(3S)=133

4S+15S=133

19S=133

S=7 ANSWER 1: The smaller number is 7.

L=3S=3(7)=21 ANSWER 2: The larger number is 21.

.

CHECK:

4S+5L=133

4(7)+5(21)=133

28+105=133

133=133

Answer:

The larger number is 98

Step-by-step explanation:

Let the numbers be a and b

a/b= 2/4

4a = 2b ------- 1

a + b = 147 -----2

a= 147 - b -------3

Substitute equation 3 into 1

4(147 -b) = 2b

588 - 4b = 2b

588= 2b + 4b

588 = 6b

b= 588/6

b= 98

Substituting b= 98 into 1

4a = 2(98)

4a = 196

a= 49

The larger number is 98

Answer: -1/3x - 6

Step-by-step explanation: perpendicular lines have opposite reciprocal slopes

original slope of 3 —-> -1/3

then our point is (0, -6) let’s plug that into y=-1/3x+b

-6 = -1/3(0)+b

b= -6

put it all together: y = -1/3x -6

Step-by-step explanation:

Answer:

a + b

Step-by-step explanation:

ax + ay + bx + by

a(x +y) +b(x + y)

(a + b) ( x + y)

therefore (a + b) ( x + y) divide x+y

x + y is canceled out both in the denominator and numerator

= a+b
