Answer:99.2

Step-by-step explanation:

Speed = distance÷time

496÷5=99.2

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

Answer:

19/28 or about 68%

Step-by-step explanation:

7 + 12 + 9 = 28

7 + 12/28

19/28

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

BTW what is meant by point in the last blank?

Answer:

equation y = 3x-1

slope = 3

about the point blank I'm not sure what it is asking for

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:

[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:

x = 7cm

Step-by-step explanation:

[tex]\frac{36}{6} = \frac{42}{x}\\\\6 = \frac{42}{x}\\\\x = \frac{42}{6} = 7[/tex]

Answer:

A : 146

Step-by-step explanation:

Since the lines AB and CD are parallel, we know that the angle opposite to BDC is also 34. To find ABD we can do 180-34 , which gives us 146

Answer:

=(3+9/2  ,    5+8/2)

=(12/2    ,     13/2)

=(6   ,    13/2)            

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

Answer:

The answer is most likely C.

Step-by-step explanation:

Using the Pythagoras' Theorem, c^2 = a^2 + b^2

I'm not sure if 242 and 262 were 24^2 and 26^2 respectively but I'm using 24^2 and 26^2 for this answer.

The c^2 is in fact x^2 where x is the hypotenuse.

However, the answer could be A if x has to be whole number. In this case, x^2 + 24^2 = 26^2

x^2 = 26^2 - 24^2 = 100

x = sqrt (100) = 10

all real numbers are greater than or equal to 2

Answer:

B, 90

Step-by-step explanation:

a right angle is exactly 90 degrees

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:

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.

Answer:

number of people work in service jobs

[tex]949 \: 200 \times \frac{20}{100} \\ 189 840[/tex]

answer is option C

533/100 then simplify

5 and 33/100

But that isn't an option and none of those options convert into 5.33, and I haven't been able to solve 3.75 repeating yet nor think it would convert into 5.33 anyhow. Please correct me if I'm solving this wrong.

Answer:

Use the distributive property to multiply 3 by x−2.

y=(3x−6)(x+1)(x−4)

Use the distributive property to multiply 3x−6 by x+1 and combine like terms.  y=(3x  2  −3x−6)(x−4)

Use the distributive property to multiply 3x  2 −3x−6 by x−4 and combine like terms. y =3x  3 −15x  2  +6x+24
