Peter is making green paint by mixing blue and yellow paint in a cuboid container, shown below. The container has width of 30cm
dusya [7]

Answer: height = 17.5cm

Step-by-step explanation: Peter mixes blue and yellow paint in the ratio 2:3, which means:

\frac{2}{3} = \frac{8.4}{x}

x = \frac{8.4*3}{2}

x = 12.6L

The container is full with the two paints, so total volume:

V = 12.6 + 8.4

V = 21L

Knowing that 1L = 1dm³ and sides of cuboid is measure in cm:

V = 21dm³ = 21000cm³

Volume of a cuboid is calculated as:

V = width*length*height

Height of the container is

height = \frac{V}{width*length}

height = \frac{21000}{30*40}

height = 17.5cm

The height of the container is 17.5cm.

3. Paula commutes 60 km each day for work, five days a week, nine months of the year. She travels 720
bezimeni [28]

Answer:

16,080 km.

Step-by-step explanation:

We want the total number of kilometers in one year.

so

4 weeks /month.

for Work:   9 months in the year  60 km/day  5 days/week

Family Visit :  720 km for 4 times a year

Personal:  200 km / month

Work total = 60 km/day * 5 days/week * 4week/month * 9 months

WorkTotal= 60*5*4*9 = 10,800 km

FamilyTotal= 4*720 = 2880 km

Personal = 200*12 = 2400 km

Total = 10,800 + 2880 + 2400 = 16,080 km

What is the distance of the line?<br> Remember the distance formula is (23 - 23) + (42 -
vivado [14]

Answer:

<em>The distance of the line is 10.82</em>

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The graph clearly shows the points (-5,4) (4,-2), thus the distance is:

d=\sqrt{(4-(-5))^2+(-2-4)^2}=\sqrt{9^2+(-6)^2}

d=\sqrt{81+36}=\sqrt{117}=10.82

The distance of the line is 10.82
