That all dolphins have different sizes and are mostly different ages
To determine the expression that is equivalent to 8a + 20, all you have to do is find the common denominator and divide the values by it.
8a + 20
8a/4 + 20/4
4(2a + 5).
The correct solution would cue the second option - 4(2a + 5).
Answer:
0.3 units
Step-by-step explanation:
The ratio of the length of the arc to the circumference of the circle is proportional to the ratio of the central angle to the sum of angle in a circle.
This implies that:
This simplifies to: 
Answer:
The probability that a student taking only math will get picked is approximately 29%
Step-by-step explanation: This is because out of the total number of students taking math (95), 52 of such students are also taking science. In order to get the number of students only taking math you have to do 95-52=43 and to put that against the amount of total students the ratio would be 43:147 or 42/147 and if you plug 42/147 into a calculator you will recieve a long decimal that you can then round to 29%.
Answer:
7 feets
Step-by-step explanation:
Volume of shed, V = 357 feet³
Height of shed, H= 8 1/2 fts
Width of shed, W = 6 ft
Using the relation :
Volume = Length * width * height
357 = L * 6 ft * 17/2 feets
357 feets³ = L * 51 feets²
L = 357 feets³ / 51 feets²
Length, L = 7 feets
