Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.
600 / 6 = 100
10 x 10 = 100

Answer:
9.y=Mx+b
Y= 2/5x+4
10. y=Mx+b
Y=4x-5
Step-by-step explanation:
Answer:
9) [tex]y=\frac{2}{5} x+4[/tex]
10) [tex]y=4x-5[/tex]
Step-by-step explanation:
Slope-intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept, or the value of y when the line crosses the y-axis.
Question 9
[tex]y=mx+b[/tex]
The question tells us that the slope of the line is [tex]\frac{2}{5}[/tex]. Because the slope is [tex]m[/tex], plug [tex]\frac{2}{5}[/tex] into the equation as [tex]m[/tex].
[tex]y=\frac{2}{5} x+b[/tex]
Then, it tells us that the y-intercept is (0,4). Recall that the y-intercept is the value of y when the line crosses the y-axis. The value of y in the point (0,4) is 4. Because the y-intercept is [tex]b[/tex], plug 4 into the equation as [tex]b[/tex].
[tex]y=\frac{2}{5} x+4[/tex]
Question 10
[tex]y=mx+b[/tex]
First, we must calculate the slope using the slope equation:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
The given points are (0,-5) and (2,3). Plug those into the equation.
[tex]\frac{3-(-5)}{2-0}[/tex]
Two negatives make a positive
[tex]= \frac{3+5}{2-0}\\= \frac{8}{2} \\= 4[/tex]
Therefore, the slope of the line is 4. Plug 4 into the original equation as [tex]m[/tex].
[tex]y=4x+b[/tex]
Now, we can find the y-intercept by simply looking at the graph. The line crosses the y-axis at the point (0,-5). Therefore, the y-intercept is -5. Plug -5 into the equation as [tex]b[/tex].
[tex]y=4x+(-5)\\y=4x-5[/tex]
I hope this helps!

A bus travels 6/8 of a mile in 12 of a minute. How far will it travel in one minute?
Find the unit rate and simplify. Show all work.
Answer:
1/16 of a mile in one minute.
Step-by-step explanation:
1. you know that 3/4 mile = 12 mins and x mile = 1 min
2. To get 12 mins to 1 you divide the mins by 12
3. So you do the same for miles!
4. 3/4 miles divided by 12
5. which turns into 3/4 * 1/12
6. so your final answer would be 1/16 of a mile in one minute

Avril cycles 10 km at x km/h and then 14 km at y km/h. Express the time for the journey as a single fraction
Step-by-step explanation:
It is given that,
Avril cycles 10 km at x km/h and then 14 km at y km/h.
We need to express the time for the journey as a single fraction.
We know that,
Speed = distance/time
or
time = distance/speed
Here, total distance = 10 +14 = 24 km/h
Total speed = x+y
So,
[tex]t=\dfrac{24}{x+y}[/tex]
Hence, this is the required solution.
