Answer:

$m=0.8$

Step-by-step explanation:

Slope m can be calculated using following formula

$m=\frac{y_2-y_1}{x_2-x_1}$ --------------(1)

Here $(x_1, y_1)=(4, 1.2) \ \ and \ \ (x_2, y_2)= (10, 6)$

Substitute values in equation (1)

$m=\frac{6-1.2}{10-4}$

$m=\frac{4.8}{6}\\m = 0.8$

Josie deposited $450 at the beginning of the month. A payment of $35.20 is automatically deducted each month for her gym members

Alinara [238K]

Answer:

You have told us that there is $450 in Josie's bank account, and she does not make any later deposits or withdraws. You have also told us that the gym deducts $35.20 every one month in fees.

Explanation:

The answer is really easy to find. All you have to do is subtract 35.20 from 450. The problem asks for the amount of money that Josie has in her account at the end of the month - the same month that she put $450 into her account.

Solve:

450 - 35.20

= 414.80

Josie has $414.80 in her bank account at the end of the month.

Tyler can rake 1/3 of a yard in 1/5 of an hour.How many yards can he rake in one hour?

zzz [600]

Answer:

5/3 yards

Step-by-step explanation:

Write a proportion:

(1/3 yard) / (1/5 hour) = x / (1 hour)

Cross multiply:

1/5 x = 1/3

Solve for x:

x = 5/3

Find the uncertainty in a calculated average speed from the measurements of distance and time. Average speed depends on distance

zzz [600]

Answer:

$\frac{\Delta v}{v}=0.426$

Step-by-step explanation:

you have that the average sped is given by the following formula:

$v(x,t)=\frac{x}{t}$

The uncertainty formula for a division is given by:

$\frac{\Delta v}{v}=\sqrt{(\frac{\Delta x}{x})^2+(\frac{\Delta t}{t})^2}$ (1)

Δv: uncertainty in speed

Δx: uncertainty in the distance = 0.9m

Δt: uncertainty in time = 0.7s

x: distance = 8.1m

t: time = 1.7s

You replace the values of all parameters in the equation (1):

$\frac{\Delta v}{v}=\sqrt{(\frac{0.9}{8.1})^2+(\frac{0.7}{1.7})^2}\\\\\frac{\Delta v}{v}=0.426$

Hence, the relation between the uncertainty in the average velocity is 0.426

List a positive and negative number whose absolute value is greater than 3. Justify your answer using the number line.

tino4ka555 [31]

Answer:

|5|, |-6|, |4|, |-3.5|...

Step-by-step explanation:

The absolute value is related with the distance between the number and the zero of the number line, then each number greater than 3 will have an absolute value greater than 3, as we can see in the picture, the numbers positive or negative will have a positive distance to the origin of the number line.
