Answer:
a=
15
b=1/3
Step-by-step explanation:
- key rule: see the graph carefully to get the following identified points.
- from the given graph, it can be seen that, the curve passes through (0,15)
- by substituting this point in y=a*(b)^x,
15=a*(b)^0
15=a
- it can also be seen that the curve passes through (1,5)
- by substituting this point in y=a*(b)^x,
5=a*b
5=15*b ( since, we have found that a=15 from the before steps)
- dividing both the sides by 15,
5/15=b=1/3
a=
15
b=1/3.
Answer:
62 cubic yards
Step-by-step explanation:
<em>This is conversion from feet to yards.</em>
<u>Step 1: Write the ratio of yards to feet.</u>
Yard : Feet
1 : 3
<u>Step 2: Find out the volume of mould</u>
1 : 3
x : 186
<em>Cross multiply</em>
3x = 186
x = 62 yards
Therefore, 62 cubic yards of concrete is needed in order to fill the mould.

Answer:
Step-by-step explanation:
Since we are given all of the necessary information we simply need to divide the total number of crayons by the total number of students that are getting crayons. This will give use the number of crayons that each student will get which will be represented by the variable x. Therefore, the equation would look like the following...
x = 48 / 6
