Answer: 
Step-by-step explanation:
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
Based on the information given in the exercise, you can draw the fish tank attached, where the dimensions are: 18 inches high (
), 14 inches deep (
), and 30 inches long (
).
The area that was convered will be the sum of the areas of all the faces, but the top of the tank.
Therefore, the area that was convered is the following:
Answer:
3 people
Step-by-step explanation:
$51/$17 = 3 people
- We know to start with $51 dollars because that is the total price of the meal.
- We also know each meal costs $17.
- Next, ask youself what we are trying to find? We are trying to find how many people are eating.
- Therefore to find that we need to take our starting amount $51 divided by $17 because that is the cost of 1 meal.
- $51/$17 = 3 people (whole cost/individual cost = # of people)
- To check this take 3 x 17 = 51 (Now we know it is correct)
- If you would like a further explanation please let me know.
Answer:
55600
Step-by-step explanation:
5.56*10^4
By definition we have to:
Acute triangle - It is a triangle that has all acute angles. An acute angle is one whose degree of measurement is less than 90.
Therefore, Charlene's definition is correct.
Charlene said:
triangle is a triangle whose three interior angles have measures less than 90 °
Answer:
C.Yes, because this definition fits all acute triangles and does not fit triangles that are not acute.
If there are real roots to be found for this polynomial, the Rational Root Theorem and synthetic division are the best way to find them. I teach from a book that uses c and d for the possible roots of the polynomial. C is our constant, 2, and d is the leading coefficient, 1. The factors of 2 are +/- 1 and +/-2. The factors for 1 are +/-1 only. Meaning, in all, there are 4 possibilities as roots for this polynomial. But there are only 3 total (because our polynomial is a third degree), so we have to find the first one, at least, from our possibilities above. Let's try x = -1, factor form (x + 1). If there is no remainder when we do the synthetic division, then -1 is a root. Put -1 outside the "box" and the coefficients from the polynomial inside: -1 (1 2 -1 -2). Bring down the first coefficient of 1 and multiply it by the -1 outside to get -1. Put that -1 up under the 2 and add to get 1. Multiply 1 times the -1 to get -1 and put that -1 up under the -1 and add to get -2. -1 times -2 is 2, and -2 + 2 = 0. So we have our first root of (x+1). The numbers we get when we do the addition along the way are the coefficients of our new polynomial, the depressed polynomial (NOT a sad one cuz it hates math, but a new polynomial that is one degree less than that of which we started!). The new polynomial is
. That can also be factored to find the remaining 2 roots. Use standard factoring to find that the other 2 solutions are (x+2) and (x-1). Our solutions then are x = -2, -1, 1, choice B from above.
