Answer:
$28.95
Step-by-step explanation:
Sam started out with x dollars.
We represent this situation with the following formula:
x - ($4.85 + $7.95 + $7.95) = $8.20.
Then:
x - $20.75 = $8.20.
To isolate x, we add $20.75 to both sides of this equation, obtaining:
x = $28.95.
Sam started out with $28.95.
<u>Given</u>:
Given that an aquarium is being filled with water.
The given graph shows the height of the water over time as the aquarium is being filled.
We need to determine the slope of the graph.
<u>Slope</u>:
The slope of the given graph can be determined using the formula,
Since, the slope is same for all the points on the straight line, then let us consider the points (2,5) and (4,10)
Substituting these points in the above formula, we get;
Simplifying, we get;
Thus, the slope of the given graph is 2.5
We are given a parallelogram with sides:
3 1/8 and 2 3/16.
Let us convert each into improper fraction.
3 1/8 = 25/8
2 3/16 = 35/16
Now perimeter of parallelogram is given by:
Now we have to find lcd of 8 and 16.
lcd of 8 and 16 is 16.
Perimeter = 85/8 km
Answer : Perimeter of parallelogram is given by 85/8 km.
Answer:
the fourth one
Step-by-step explanation:
Answer:
B: 21.99
Step-by-step explanation:
recall that for a circle, circumference is given by:
circumference = 2π x radius
= π x diameter
we are given taht the diameter is 7 cm and π = 3.14
simply substitute these values into the formula for circumference:
circumference
= π x diameter
= 3.14 x 7
= 21.98
(the closest answer to this is B: 21.99)
