Answer:
2.8 in
Step-by-step explanation:
The volume of any shape is given as the product of base area and height. Therefore, V=Ah
Where A is cross sectional area, h is height
For a triangular, the cross sectional area is given by ½lw where l is length and w is width.
Now v=½lwh
Given that v=4 in³
4=½lwh
8=lwh
Considering the given choices, l can be 2.8 in
Answer:
Cost of 5 yards of fabric = $5
Step-by-step explanation:
Cost of one foot fabric = $3
John needs fabric = 5 yards
Since, 1 yard = 3 foot
Therefore, 5 yards = 3 × 5
= 15 foot
Total cost of fabric = total length of fabric × Cost of 1 foot fabric
= 15 × 3
= $45
5 yards of fabric will cost $45.
The number of cells of strain A follow the linear model
, where
denotes the number of cells of that strain and
is time in hours. Meanwhile, strain B follows
. The time
when both strains have the same number of cells is the intersection of these two lines, or the solution to
You have
so after 5 hours, both strains should have the same number of cells.
