Answer:

Speed = 3.75 miles per hour.

Step-by-step explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

$Speed = \frac{distance}{time}$

$S = \frac{d}{t}$

Given the following data;

Distance, d = 3/4 miles

Time, t = 1/5 hour

Substituting into the equation, we have;

$Speed, S= \frac{3/4}{1/5}$

$Speed, S = \frac{3}{4}*5$

$Speed, S = \frac{15}{4}$

Speed, S = 3.75mph.

Therefore, Josie's speed is 3.75 miles per hour.

IRINA_888 [86]

Step-by-step explanation:

1 Remove parentheses.

8{y}^{2}\times -3{x}^{2}{y}^{2}\times \frac{2}{3}x{y}^{4}

×−3x

2 Use this rule: \frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}

\frac{8{y}^{2}\times -3{x}^{2}{y}^{2}\times 2x{y}^{4}}{3}

×−3x

×2xy

3 Take out the constants.

\frac{(8\times -3\times 2){y}^{2}{y}^{2}{y}^{4}{x}^{2}x}{3}

(8×−3×2)y

4 Simplify 8\times -38×−3 to -24−24.

\frac{(-24\times 2){y}^{2}{y}^{2}{y}^{4}{x}^{2}x}{3}

(−24×2)y

5 Simplify -24\times 2−24×2 to -48−48.

\frac{-48{y}^{2}{y}^{2}{y}^{4}{x}^{2}x}{3}

−48y

6 Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}x

a+b

\frac{-48{y}^{2+2+4}{x}^{2+1}}{3}

−48y

2+2+4

2+1

7 Simplify 2+22+2 to 44.

\frac{-48{y}^{4+4}{x}^{2+1}}{3}

−48y

4+4

2+1

8 Simplify 4+44+4 to 88.

\frac{-48{y}^{8}{x}^{2+1}}{3}

−48y

2+1

9 Simplify 2+12+1 to 33.

\frac{-48{y}^{8}{x}^{3}}{3}

−48y

10 Move the negative sign to the left.

-\frac{48{y}^{8}{x}^{3}}{3}

−

48y

11 Simplify \frac{48{y}^{8}{x}^{3}}{3}

48y

to 16{y}^{8}{x}^{3}16y

During a fundraiser, Ms. Dawson’s class raised $560, which is 25% more than Mr. Casey’s class raised. How much money did Mr. Cas

evablogger [386]

Answer:

$420

Step-by-step explanation:

To work this out you would need to find the 25% decrease of 560. To do this you would first divide 25 by 100, which gives you 0.25. Then you would minus 0.25 from 1, which gives you 0.75. This is because when finding percentage decreases you would first have to convert it into a decimal. Then you would have to minus it from 1 , to make sure that it will be a 25% decrease not a 75% decrease. Then you would multiply 560 by 0.75, which gives you 420.

1) Divide 25 by 100.

$25/100=0.25$
