Answer:
D = S x T (Distance = Speed x Time)
S = D / T
T = D / S

When I need to drive to a neighboring state for my job, I look on maps
and find out how far away my destination is, and then use this formula
to calculate how long it will take me to get there, how fast I need to drive
in order to get there in the amount of time I have, how far I can get in the
time I have if I drive only at safe and legal speed, and what time I need to
head back in order to get home in time for dinner..

F = 1.8C + 32
C = 0.55 (F - 32)

These are the formulas to convert between Fahrenheit and Celsius expressions
of temperature. I use them when I'm discussing the weather with my daughter
in Israel, or with my customers almost anywhere outside the USA.

F = M x G
Weight = Mass x Gravity

This formula deals with the relationship between mass and weight. It's
used when you need to calculate the weight of some particular mass on
some particular planet. I use it almost every day, when I'm answering
questions in the Physics department on Brainly, and trying to explain
my answers.

-384

Step-by-step explanation:

(Un) is a geometric sequence

Its first term U1 = -3

Its common ratio q = 2

then U8 = U1×q⁸⁻¹

= (-3)×2⁷

= -384

The following table shows the distance from the bus stop as a function of time:Time (in minutes)
x Distance (in meters)
f(x)
0 45
3 40
6 35
9 30
12 25

Find and interpret the meaning of the x-intercept in this scenario.
(45, 0); the distance away from the bus stop
(27, 0); the time it takes to reach the bus stop
(45, 0); the time it takes to reach the bus stop
(27, 0); the distance away from the bus stop

Answers

Answer: LAST OPTION.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

Find the slope of the line with this formula:

$m=(y_2-y_1)/(x_2-x_1)$

Choose two points from the table and substitute the coordinates into the formula. Then, the slope is:

$m=(40-45)/(3-0)=-(5)/(3)$

By definition, the line intersects the y-axis when the value of "x" is zero ( $x=0$ ).

Based on the table, the y-intercept is:

$b=45$

Then the equation of the line is:

$y=-(5)/(3)x+45$

The line intersects the x-axis when the value of "y" is zero ( $y=0$ ), then you can substitute these value into the equation and solve for "x":

$0=-(5)/(3)x+45\n\nx=27$

So, you get the point:

$(27,0)$

Since the table shows the distance from the bus stop as a function of time, you can conclude that meaning of the x-intercept in this scenario is: "The distance away from the bus stop".

Answer: (27, 0); the distance away from the bus stop

Mrs Smith has 12 times as many markers as color pencils the total number of markers and colored pencils is 78 how many markers does Mrs Smith have

Answers

x = markers
y = colored pencils

12x = y

x= 72
y = 6

Okay, so what I did was divide 78 by 12 (to find the number of colored pencils) which gave me 6.5. You can't have half a colored pencil, so I rounded the number down to get 6. To find the number of markers, I multiplied 12 and 6 (12x = 6) which gave me 72. To check my answer I added the two amounts, 72 + 6, which gave me 78.

Kate made a box to hold her jewelry collection. She used 42 inches of wood to build the sides of the box. If the box was 9 Inches wide, how long was the box?

Answers

Assuming that the sides of the box are square (having 90° angles on all four corners), then it should be relatively easy for us to find the length of the box, given the perimeter and the length of one side.
We know the length of all sides combined is 42 inches, and that the length of one side is 9 inches. With a rectangular prism, the length of one side is the same as the length of the opposite side, so there are two sides that measure 9 inches.
All we need to do to find the measure of both the other sides' lengths is subtract the known lengths from the total length.

9 + 9 = 18

42 - 18 = 24

So the rest of the side lengths added together is 24 inches.
There are two sides left, so all we have to do is divide by 2 to find the length of the box.

24 / 2 = 12

The length of Kate's jewelry box is 12 inches.
Hope that helped =)

there are 118 boys and 121 girls signed up for a volleyball league. The coaches first make teams of 9 players and then assign any remaining players to make some of the teams have 10 players.how many teams of 10 players. how many teams of 9 players

Answers

The number of nine-players team= 21 teams.

The number of ten-players team= 5 teams.

Step-by-step explanation:

step 1: The total players signed up for a volleyball league= 118 boys+121 girls= 239 players.

step 2: The coach first makes a 9 players team= 239-9= 230 members

In this stage, the number of 9 players-team is one.

step 3: The remaining 230 players cannot be divided equally into 9 players, since 230 is not divisible by 9.

step 4: Find the number within 230 that is divisible by 9 as a whole. Check for easy number (9*20= 180 is within 230)

Therefore, 230-180= 50 players are remaining.

In this stage, the number of 9 players-team= 1+20= 21 teams with 9-players.

The number of 10 players-team= 50 players/10= 5 teams with 10-players.

Round 18,300,000 to the nearest tenth

Answers

Answer:

18,300,000

Step-by-step explanation:

the problem here is that there is no tenth, hundreth, or ten thousandth place

they try to confuse you so all you have to do is round the closest number to the tenth place which is 3 and 0 can't do anything so it stays the same.
