Answers

Answer:

Quadrant 2

Shawn uses 45N of force to stop the cart 1 meter from running his foot over. How much work does he do?​

Answers

Answer:

[tex]\boxed {\boxed {\sf 45 \ Joules}}[/tex]

Step-by-step explanation:

Work can be found by multiplying the force by the distance traveled in the direction of the force.

[tex]W=F*d[/tex]

The force is 45 Newtons.

The distance traveled is 1 meter.

[tex]F=45 \ N \\d= 1 \ m[/tex]

Substitute the values into the formula.

[tex]W=45 \ N * 1 \ m[/tex]

Multiply.

[tex]W=45 \ N*m[/tex]

1 Newton meter is equal to 1 Joules.

Therefore our answer of 45 Newton meters is equal to 45 Joules.

[tex]W= 45 \ J[/tex]

The work done is 45 Joules.

Step-by-step explanation:

[tex]\sf Required\:Answer\begin{cases} \sf Force_(f)=45N \\ \sf Distance_(d)=1m \\ \sf As\:we\:know\:that \\ {\boxed{\sf Work_(w)=Force_(f)\times Distance_(d)}} \\ \sf W=45 \times 1Nm \\ \sf =45Nm \\ \longrightarrow {\underline{\boxed{\bf W=45Joule}}}\end {array}[/tex]

5) Ziegler is using paper for an art project
thatis 0.025 mm thick. If she glues a layer
of thepaper onto a construction board with
athickness of 7 * 10^-2 mm, what will the
total thickness of the paper and the
construction
board be? Write your ansicer
in scientific notation

Answers

Answer:

9.5 * 10^-2 mm

Step-by-step explanation:

To find the total thickness, we proceed to add the two thickness that we have

Mathematically, this will be;

0.025 mm + 7 * 10^-2 mm

7 * 10^-2 mm = 0.07

So we have;

0.025 mm + 0.07 mm = 0.095

In scientific notation, this is 9.5 * 10^-2 mm

Three drivers competed in the same fifteen drag races. The mean and standard deviation for the race times of each of the drivers are given.


- Driver A had a mean race time of 4.01 seconds and a standard deviation of 0.05 seconds.

- Driver B had a mean race time of 3.96 seconds and a standard deviation of 0.12 seconds.

- Driver C had a mean race time of 3.99 seconds and a standard deviation of 0.19 seconds.


Which driver do you predict will win the next drag race? Support your prediction using the mean and standard deviation.

Answers

Answer:

Driver B

Step-by-step explanation:

From the given options, Driver B will win the next race because the previous result shows that Driver B has the fastest race time due to the fact that it recorded the lowest mean race time.

Similarly, the standard deviation of 0.12 seconds illustrates that the driver keep-up with the bearest minimum time frame all through the entire race time.

Answer:

It is B and the other one is Driver C if you have that question

Find BA
CB + BA = CA
7x-2 + 5x+1 = 23

Answers

Answer:

BA = 11

Step-by-step explanation:

CB + BA = CA , substitute values

7x - 2 + 5x + 1 = 23, that is

12x - 1 = 23 ( add 1 to both sides )

12x = 24 ( divide both sides by 12 )

x = 2

Thus

BA = 5x + 1 = 5(2) + 1 = 10 + 1 = 11

since CB + BA = CA,
sub. in all the values :
7x - 2 + 5x + 1 = 23

find the value of x :
7x + 5x = 23 + 2 - 1
12x = 24
x = 2

sub. in the value of x into (5x + 1),
BA = 5(2) + 1
BA = 10 + 1
BA = 11

i think it is 10 and 11

The smallest possible values for the integers will be 11 and 12.

What exactly is simplification?

Simplifying means making something easier to do or comprehend, as well as making something less difficult.

Let the two consecutive integers will be x and y.

From the given conditions the sum of two consecutive integers is greater than 21;

x+y>21

11 and 12 are the only two consecutive digits has the sum of 21.

11+12>21
