Answer:

v = 0.0229 km/h

Step-by-step explanation:

Given that,

Distance, d = 68,732 milometers = 0.0687 km

Time, t = 3 hours

We need to find the speed of the rocket. The speed of an object is given by :

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{0.0687}{3}[/tex]

v = 0.0229 km/h

So, the speed of the rocket is 0.0229 km/h.

Step-by-step explanation:

let the integer be x.

-7(x+3)=84

Step-by-step explanation:

let the integer be x

(x+3) -7 =84

-7x-21=84

-7x=84+21

-7x=105

divide both sides by -7

x= -15

Answer:

Using the distance formula, we can find the distance between them as a function of time t:

Answer:

37°C

Step-by-step explanation:

The normal body temperature of a human is 98°F. To convert it into Celsius we know the realtion between Celsius and Farenheight as ,

Equivalents: -12/10, -18/15, -24/20, - 30/25, -36/30

[tex](2)\ -\frac{8}{10}[/tex]

Equivalents: -4/5, 16/20, -24/30, -32/40, -80/100

Step-by-step explanation:

Given

[tex](1)\ -\frac{6}{5}[/tex]

[tex](2)\ -\frac{8}{10}[/tex]

Required

5 equivalent numbers for each

To do this, we carry out the same operation on the numerator and the denominator of the fraction

[tex](1)\ -\frac{6}{5}[/tex]

Multiply by 2/2

[tex]-\frac{6}{5} * \frac{2}{2} = -\frac{12}{10}[/tex]

by 3/3

[tex]-\frac{6}{5} * \frac{3}{3} = -\frac{18}{15}[/tex]

by 4/4

[tex]-\frac{6}{5} * \frac{4}{4} = -\frac{24}{20}[/tex]

by 5/5

[tex]-\frac{6}{5} * \frac{5}{5} = -\frac{30}{25}[/tex]

by 6/6

[tex]-\frac{6}{5} * \frac{6}{6} = -\frac{36}{30}[/tex]

[tex](2)\ -\frac{8}{10}[/tex]

Divide by 2/2

[tex]-\frac{8}{10}= -\frac{8/2}{10/2}[/tex]

[tex]-\frac{8}{10}= -\frac{4}{5}[/tex]

Multiply by 2/2

[tex]-\frac{8}{10} =-\frac{8*2}{10*2}[/tex]

[tex]-\frac{8}{10}= -\frac{16}{20}[/tex]

Multiply by 3/3

[tex]-\frac{8}{10}= -\frac{8*3}{10*3}[/tex]

[tex]-\frac{8}{10} =-\frac{24}{30}[/tex]

Multiply by 4/4

[tex]-\frac{8}{10} = -\frac{8*4}{10*4}[/tex]

[tex]-\frac{8}{10}= -\frac{32}{40}[/tex]

Multiply by 10/10

[tex]-\frac{8}{10}= -\frac{8}{10} * \frac{10}{10}[/tex]

[tex]-\frac{8}{10}= -\frac{80}{100}[/tex]

the equation of the graph in slope intercept form.

[tex]y=2x+9[/tex]

Given :

We are given with the graph of a line

Slope intercept form of a line is y=mx+b

where m is the slope and b is the y intercept .

To find out slope m we use slope formula

Lets pick any two points from the graph

[tex](0,9) and (1,11)[/tex]

Apply slope formula

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{11-9}{1-0} =2[/tex]

Slope is 2

Y intercept is the point where the graph crosses y axis

Graph crosses y axis at (0,9)

y intercept b=9

Now we frame equation of line using slope and y intercept

[tex]y=mx+b\\y=2x+9[/tex]

Answer:

110

Step-by-step explanation:

took the same test 1 week ago

Answer:

110 words

Step-by-step explanation:

What we know:

- Snigdha can type 550 words in 30 minutes

1) Find how many words they can type in 1 minute

To do this, divide 550 words by 30 minutes:

550÷30=18.3333... words

Therefore, Snigdha can type approximately 18 words in one minute.

2) Multiply 18 words by 6 minutes

18.3333...×6=110

Therefore, Snigdha can type 110 words in 6 minutes.

Answer:The Answer is C

Step-by-step explanation:

The value of the constant in the equation below is 100. So, the correct option is (C).

Height also known as elevation is defined as the vertical distance either between the top and bottom of something or between a base and something above it. It refers to something measured vertically high or low.

Height is body measurement usually measured in feet (feet) + inch (in) and centimeter (cm) where these are length measurements, so the SI unit will be meter.

Height equation: H= C/W

where, H is the height, C is the constant and W is the width.

We choose a point given in the graphic, I will choose (4,25), which means that when W=4  and H=25 . We use this to find the constant. So

25=C/3

C= 100

Thus, the value of the constant in the equation below is 100. So, the correct option is (C).

Step-by-step explanation:

Answer:

the maximum amount of people would be 288, 500 and the minimum would be 271,500

Step-by-step explanation:

basically if the average number is 280,000 all we have to do is add and subtract 8,500 to find the maximum and minimum

There could be up to 288.500 persons present, with a minimum of 271,500.

Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

The average number is 280,000 all we have to do is add and subtract 8,500 to find the maximum and minimum.

Maximum = 2800000 + 8500 = 288,500

Minimum = 271,500 - 8500 = 263000

Therefore, there could be up to 288.500 persons present, with a minimum of 271,500.
