Solve the following multiplication and division problems.

algol13

Answer:

a. 22.5 km

b. 267.52 m

c. 95 m

d. $(4.2)(10^{-5})$ km

Step-by-step explanation:

a. You can convert from hectometers to kilometers, and then you can make the multiplication:

$\frac{5hm}{10}=0.5km$

$(3km)(0.5km)(15)=22.5km$

b. You can convert from centimeters to meters, and then you can make the multiplication:

$\frac{44cm}{100}=0.44m\\(19m)(0.44m)(32)=267.52m$

c. You only need to divide 1,140 meters by 12:

$\frac{1,140m}{12})=95m$

d. You can convert from hectometers to kilometers, from decameters to kilometers and from meters to kilometers, and divide this by 15:

$\frac{6hm}{10}=0.6km$

$\frac{7dam}{100}=0.07km$

$\frac{5m}{1000}=0.005km$

$\frac{(3km)(0.6km)(0.07km)(0.005km)}{15}=(4.2)(10^{-5})$ km

What is the equation of the line in the following graph? 1)y=x+2

Levart [38]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (2, 0) and (-2, -4). Substitute:

$m=\dfrac{-4-0}{-2-2}=\dfrac{-4}{-4}=1$

Therefore we have the equation of a line

$y=1x+b\to y=x+b$

Put the coordinates of the point (2, 0) to the equation:

$0=2+b$ subtract 2 from both sides

$-2=b\to b=-2$

Answer: $\boxed{y=x-2}\to\boxed{3)}$
