The ratio is equivalent to 3:18 is 7:42.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Ratio = 3:18

         = 1: 6

1. 6:21

= 3:7

2. 5:20

= 1:4

3. 7:42

= 1:6

4. 12:2

= 6:1

Hence, the ratio is equivalent to 3:18 is 7:42.

Answer: Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.

Step-by-step explanation: I just got it correct on Edge :)

The true option about the randomized design is (c) Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.

The given parameters are:

[tex]\mathbf{n = 60}[/tex]

[tex]\mathbf{Batches = 4}[/tex]

[tex]\mathbf{Cookies= 15}[/tex] ---- the number of cookies in each batch

[tex]\mathbf{Temperature= 300,325,350,375}[/tex]

To randomly assign the cookies to the given temperatures, all cookies have to be subjected to the same conditions (except the difference in the temperature).

This means that, she can bake all the cookies at once at different temperatures, while noting down the cookies with a given number.

Hence, the true option is (c)

Answer:

4 Hours

Step-by-step explanation:

The original boating fee is $60 then you add $20 per hour so 20 x 4 = 80

80+60=140 $140

Answer: 140=60+20x. He kept the boat for 4 hours

Step-by-step explanation:

x=hours

y=final cost and the final cost is $140

to find x you would use the equation: 140=60+20x

you would first subtract 60 from both sides and you would get:

80=20x

Now you would divide 20 from both sides

So x is 4

Answer:

Step-by-step explanation:

The Pythagorean theorem (see Hint) tells you the length of the hypotenuse (c) is ...

  c² = 1² + 1² = 2

  c = √2 ≈ 1.4142136 . . . units

The estimated value of the length of the hypotenuse is 1.41 units.

__

Of course the shaded square will have an area that is the square of that value:

  area = s² ≈ 1.41² ≈ 1.99 . . . . . rounded to hundredths

The estimated area of the square is 1.99 square units.

__

Additional comment

Of course, we don't have to estimate. We can use the exact value of the side length to determine the shaded square has an area of ...

  area = s² = (√2)² = 2 . . . . exactly

We can also get there by recognizing that the lengths of 1 represent half the length of each of the diagonals of the square. That is, the square's diagonals are both of length 2. The area is half their product, so is (1/2)(2·2) = 2 square units.

Answer:

Infinitely many

Step-by-step explanation:

Equation: 5x + 3(x - 1) = 10x - 2x - 3

1) 5x + 3x - 3 = 10x - 2x - 3

2) 8x - 3 = 8x - 3

3)  8x = 8x

4) x = x

Based on this information, it seems that the best answer would be infinitely many solutions.

Answer:

Step-by-step explanation:

a) Let's [tex]x[/tex] the length of the side of the small square.

Thus,

[tex]x^{2} + (\sqrt{40})^2 = (\sqrt{50})^2[/tex]

[tex]x^{2} + 40 = 50[/tex]

[tex]x^{2} = 50 - 40[/tex]

[tex]x^{2} = 10[/tex]

[tex]x = \sqrt{10}[/tex]

[tex]x=3.16[/tex]

Answer:

for president there are 10, and in vice president there are 9

Answer:

a = 15, b = -14

Step-by-step explanation:

From the question,

a/5 - b/2 = 10

Multiply all through by 10

(a/5)10 - (b/2)10 = 10×10

2a - 5b = 100...................... Equation 1

a - b = 29 ........................ Equation 2

Solving equation(1 ) and equation (2) simultaneously

using elimination  method,

multiply equation (2) by 2.

2a - 2b = 58.................... Equation 3

Substract equation 3 from equation 1

2a - 2a -5b-(-2b) = 100-58

0 - 5b+2b = 42

-3b = 42

b = 42/-3

b = -14.

Substitute the value of b into equation 2

a - (-14) = 29

a +14 = 29

collect like terms

a = 29-14

a = 15.

Hence, a = 15, b =-14

Answer:

The rate of change is -300 meters per minute

Step-by-step explanation:

Here, we want to get the rate of change for the given situation

Firstly, we will need to collate the points

Let us have the points as:

(time, height)

The points are;

(10,4500) and (15,3000)

The formula for the slope m representing the average rate of change is;

m = (y2-y1)/(x2-x1)

m = (3000-4500)/(15-10) = -1500/5 = -300 meters/minutes
