Answer:
8000
Step-by-step explanation:
The number will be ...
(400 m^2)/(500 cm^2) = 0.8 (m/cm)^2 = 0.8 ((100 cm)/(1 cm))^2
= 0.8·100^2 = 8000
Fiona can cut 8000 rectangles from the plastic sheeting she bought.
In the middle there are 13 units away.
Answer: You will have points plotted at +3 on the y axis, and +3 on the x axis.
The attachment shows what your graph should look like.
Step-by-step explanation:
The intercept is where the graphed line crosses an axis.
To find the y-intercept, substitute 0 for x and solve for y:
0 + y = 3. Subtracting 0, you have y = 3
So you can plot a point at +3 on the y axis.
To find the x- intercept, substitute 0 for y, and solve for x
x + 0 = 3 Again, subtracting 0, x = 3
So plot a point on the x-axis at +3
Use the line tool to connect the two points.
Answer: $16.60
Step-by-step explanation:
5.80+ 3.60= 9.40+ 3.60= 13.00+ 3.60= 16.60
So after 4 weeks he earned $16.60
Answer:
dx/dt= 0.2608 at h= 3.1 m
Step-by-step explanation:
a is the length of the ladder. a=5
by pythagorus theorem
differentiating with respect to t we get
......1
The variable h is the height of the ladder's top at time t, and x is the distance from the wall to the ladder's bottom
At h= 3.1
x^2= 6^2-3.1^2 = 9.1×2.9
x= 5.1371 m
given
putting values in 1 to get dx/dt
.
dx/dt= 0.2608 at h= 3.1 m
