Answer:

69.115

Step-by-step explanation:

Answer:

The perimeters are in the same ratio as the corresponding sides.

Step-by-step explanation:

There is no diagram given in your question, so imagine an example in which the ratio of two corresponding sides is, say,  7:4  (or 7/4).  Then the perimeters are in the same ratio,  7:4.

Note: The areas are in the ratio which is the square of the ratio of sides, so 49:16 in the example.

Answer:

Step-by-step explanation:

1.5x - 8 = 7

=> 1.5x = 7 + 8

=> 1.5x = 15

[tex] = > \frac{15x}{10} = 15[/tex]

[tex] = > x = 15 \times \frac{10}{15} [/tex]

=> x = 10 (Ans)

Answer:

x=10

Step-by-step explanation:

Simplifying

1.5x + -8 = 7

Reorder the terms:

-8 + 1.5x = 7

Solving

-8 + 1.5x = 7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 1.5x = 7 + 8

Combine like terms: -8 + 8 = 0

0 + 1.5x = 7 + 8

1.5x = 7 + 8

Combine like terms: 7 + 8 = 15

1.5x = 15

Divide each side by '1.5'.

x = 10

Simplifying

x = 10

Answer:

Step-by-step explanation:

here x1=9  y1=8  x2=3  y2=5

midpoint=(x2+x1/2   ,   y2+y1/2)

=(3+9/2  ,    5+8/2)

=(12/2    ,     13/2)

=(6   ,    13/2)            

Answer:

Step-by-step explanation:

(-5,4)=since x coordinate is negative and y coordinate is positive it lies on 2 nd quadrant.

(4,-2)=x coordinate is positive and y coordinate is negative so it lies on 4 th quadrant

(7,2)=both x coordinate and y coordinate are positive so they lie in 1 st quadrant.

(-3,-7) =both x and y coordinate are negative so they lie on 3 nd quadrant

Answer:

She kayaked for 6 hours.

Step-by-step explanation:

If $10 is the initial fee, subtract $22 - $10 = $12.

If it charges $2 per hour, divide $12 by $2 which equals 6 hours.

Answer:

6 hours

Step-by-step explanation:

Cost = fee + charge per hour * number of hours

22 = 10 +2h

Subtract 10 from each side

22-10 = 10+2h-10

12 = 2h

Divide

12/2 = 2h/2

6 = h

Answer:

[tex]h_{max} = 14.2m[/tex]

[tex]t = 1.2[/tex]

The height of the diver is 7m

Step-by-step explanation:

Given

[tex]h(t) =-5t^2 + 12t + 7[/tex]

Solving (a): The maximum height reached

First, we calculate the time to reach the maximum height using:

[tex]t = - \frac{b}{2a}[/tex] --- maximum of a function

Where

[tex]a = -5; b = 12; c = 7[/tex]

So, we have:

[tex]t = -\frac{12}{-2 * 5}[/tex]

[tex]t = \frac{12}{10}[/tex]

[tex]t = 1.2[/tex]

So, the maximum height is:

[tex]h(t) =-5t^2 + 12t + 7[/tex]

[tex]h(1.2)=-5 * 1.2^2 + 12 * 1.2 + 7[/tex]

[tex]h(1.2)=14.2[/tex]

Hence:

[tex]h_{max} = 14.2m[/tex]

Solving (b): Time to reach maximum height

This has been calculated in (a)

[tex]t = 1.2[/tex]

Solving (c): Height of the board.

This can be calculated by setting [tex]t =0[/tex] --- i.e. the height of the diver before diving

So, we have:

[tex]h(t) =-5t^2 + 12t + 7[/tex]

[tex]h(0) = -5 * 0^2 + 12 * 0 + 7[/tex]

[tex]h(0) = 7[/tex]

Answer:

see below

Step-by-step explanation:

The steps are +2 then *4 then -8 then ÷2

Input  is 5

5 +2 =7 *4 = 28-8 = 20 ÷2 = 10     Output is 10

Input  is 9

9 +2 =11 *4 = 44-8 = 36 ÷2 = 18     Output is 18

Input  is 14

14 +2 =16 *4 = 64-8 = 56 ÷2 = 28     Output is 28

Input  is 18

18 +2 =20 *4 = 80-8 = 72 ÷2 = 36     Output is 36

Input  is 23

23 +2 =25 *4 = 100-8 = 92 ÷2 = 46     Output is 46

Input  is 7.5

7.5 +2 =9.5 *4 = 38-8 = 30 ÷2 = 20     Output is 20

Input  is 11.54

11.54 +2 =13.54 *4 = 54.16-8 = 46.16 ÷2 = 23.08     Output is 23.08

Answer:

Output:

5 + 2 x 4 - 8 ÷ 2 = 9

9 + 2 x 4 - 8 ÷ 2 = 13

14 + 2 x 4 - 8 ÷ 2 = 18

18 + 2 x 4 - 8 ÷ 2 = 22

23 + 2 x 4 - 8 ÷ 2 = 27

7.5 + 2 x 4 - 8 ÷ 2 = 11.5

11.54 + 2 x 4 - 8 ÷ 2 = 14.54

Answer:

i think its 4

Step-by-step explanation:

Answer:

3rd option

Step-by-step explanation:

The sum to infinity of a geometric sequence is

S = [tex]\frac{a}{1-r}[/tex]

where a is the first term and r the common ratio

The expression inside the summation is

6 [tex](\frac{1}{3}) ^{n-1}[/tex]

which is in the form of the nth term of a geometric sequence

with a = 6 and r = [tex]\frac{1}{3}[/tex] , then

S = [tex]\frac{6}{1-\frac{1}{3} }[/tex] ← expression required

  = [tex]\frac{6}{\frac{2}{3} }[/tex]

  = 9

C I took the quiz

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

24/18 OR 4/3 OR 1.3333...

Step-by-step explanation:

18y - 17 = 7

Add 17 from both sides.

18y = 24

Divide 18 from both sides to leave the y alone.

y = 24/18 ≈ 1.3333...

Answer:

2x + y - 6 = 0

Step-by-step explanation:

Here, C represents a constant value. So the only thing we really need to do here is subtract 6 because 6 is a constant value and because we would get 0 on the right side. I know this isn't a very good explanation so feel free to ask me any questions that you may have.

The person above this should have the answer. It seems like nobody else is answering.
